Many believe that the ultimate goal for electric transportation is the hydrogen fuel cell vehicle (FCV), with battery electric vehicles being just a step along the way. Hyundai is skipping this step and concentrating on developing and marketing FCVs. The automaker notes that affordable electric vehicle technology is best suited to smaller urban vehicles, not to larger family and utility vehicles that many families require to meet all of their needs.
To that end, Hyundai is poised to offer its next-generation Tucson Fuel Cell vehicle in Southern California Hyundai dealers starting sometime this spring. Production is taking place at the automaker’s Ulsan plant in Korea. Hyundai already began production of the ix35 Fuel Cell, the Tucson’s equivalent in Europe, at Ulsan in January 2013. Since the Ulsan plant builds the gasoline-powered Tucson CUV, this allows Hyundai to take advantage of both the high quality and cost-efficiency of its popular gasoline-powered Tucson platform.
Hyundai’s third-generation fuel cell vehicle features significant improvements over its predecessor, including a 50 percent increase in driving range and 15 percent better fuel efficiency. The Tucson and ix35 Fuel Cell are equipped with a 100 kilowatt electric motor, allowing a top speed just shy of 100 mph. Instantaneous 221 lb-ft torque from the electric motor means spritely acceleration.
Sufficient hydrogen for an approximate 370 mile range is stored in two hydrogen tanks. Refueling is accomplished in less than 10 minutes, providing daily utility comparable with its gasoline counterpart. Electrical energy is stored in a 24 kilowatt-hour lithium-ion polymer battery that’s been jointly developed with LG Chemical. The fuel cell reliably starts in temperatures as low as -20 degrees C (-4 degrees F). Unlike battery electric vehicles there is minimal capacity decrease at very low temperatures.
Hyundai’s fuel cell fleet has completed over two million durability test miles since 2000. Extensive crash, fire, and leak testing have been successfully completed. Hyundai says that high reliability and long-term durability come as a matter of course with the power-generating fuel cell stack, which has no internal moving parts.
The Hyundai Fuel Cell will be leased for $499 per month on a 36 month term, with $2,999 down. This includes unlimited free hydrogen refueling and At Your Service Valet Maintenance at no extra cost. Hyundai will initially offer the Tucson Fuel Cell in the Los Angeles/Orange County areas at four dealerships that will have hydrogen refueling capability. The automaker says that availability will expand to other regions of the country consistent with the accelerating deployment of hydrogen refueling stations.
Hyundai is also partnering with Enterprise Rent-A-Car to rent the Tucson Fuel Cell at select locations in the initial lease regions. This will allow interested consumers to evaluate the Tucson Fuel Cell for their lifestyles on a multi-day basis. Rentals are also planned sometime this spring.
The evolution of the auto industry has been no less than amazing. I have witnessed this first-hand while documenting the advent of ‘green’ cars over two decades at Green Car Journal and at Motor Trend before that. We had electric cars back in the 1990s as we do now, battling for acceptance, with other alternative fuels also jockeying for position amid an expansive field of conventional vehicles. Things change, things stay the same…although the numbers have improved for electrics.
While not particularly ‘green’ in earlier years, the automotive field did show early inclinations toward efficiency, particularly after the Arab oil embargo of the 1970s and oil disruptions of the 1980s. That was short lived as gasoline disruptions eased and gas was again plentiful and cheap. It was the 1990s, though, when industry and consumer interest in ‘green’ kicked into high gear.
The advancement of ‘green’ vehicles has largely been driven by the State of California, which has long required new vehicles to run cleaner than those meeting federal standards, a nod to the state’s epic half-century battle with urban smog. California has led the way in recent times with its milestone low emission vehicle program and its requirements for ever-cleaner running cars meeting seemingly impossible emissions goals. All this led to more stringent federal standards and, along the way, internal combustion vehicles with near-zero tailpipe emissions. It also hastened the introduction of hybrids and battery electric cars.
Early on, interest in greener cars was primarily driven by concerns such as tailpipe emissions, air quality, and petroleum dependence, the latter focused on resource depletion, the environmental cost of petroleum production, and significant dependence on imported oil. But that has evolved. The release of multiple studies singling out CO2 emissions as a major contributor to climate change added yet another reason to demand cleaner cars, with carbon emissions now a focal point. New regulations requiring much higher fuel economy in the years ahead – accomplishing the multiple goals of reducing petroleum use and lowering CO2 emissions through higher efficiency – have helped change the dynamic as well, as have the shockingly high gas prices seen late last decade. Together, they created the perfect storm for ‘green’ cars.
The cumulative result of regulations and incentives – plus an auto industry increasingly looking at ‘green’ not only as a requirement but as a market advantage – is a field of greener choices at new car showrooms. We now have internal combustion vehicles with near-zero emissions. A growing number of vehicle models are hybrids, plug-in hybrids, and battery electric cars with a few gaseous fuel models as well. The vast majority, however, are conventional vehicles that are worlds better than those of the past – gasoline and clean diesel models that achieve 35, 40, and 45 mpg or better with 50+ mpg clearly on the horizon.
While electric vehicles are often the topic du jour, it’s evident that new car buyers want the ability to pick their path to a greener driving future, choosing the vehicle, powertrain, and fuel that make them comfortable in their daily journeys. It has been satisfying to witness the auto industry’s decades-long evolution that’s now enabling consumers to do just that.
It has not been an easy road for Fisker Automotive, manufacturer of the stunning Karma extended range electric car. A series of misfortunes led to this automaker suspending production and ultimately filing for bankruptcy. Now it appears this model is poised for reemergence through China’s Wanxiang Group, the company that just won a bidding war to acquire the assets of Fisker Automotive, including its sought-after patents and its Wilmington, Delaware plant that’s valued at up to $50 million.
After 19 rounds of bidding, Wanxiang won out over another Chinese company, Hybrid Tech Holdings, with a bid valued at $149.2 million. This reportedly represents $126.2 million in cash, $8 million of assumed liabilities, and a contribution of common equity in an affiliate designated by Wanxiang to acquire the assets of Fisker Automotive. The winning bid is subject to bankruptcy court approval.
It is not yet clear whether Wanxiang will actually be able to use the name ‘Fisker’ or the Fisker logo, which apparently were licensed to Fisker Automotive through Fisker Coachbuild, a separate company co-founded by Bernie Koehler and Henrik Fisker.
In his 2011 State of the Union address, President Obama set a goal of having one million electric vehicles on the road by 2015. The million EVs would include plug-in hybrids, extended range electric vehicles, and all-electric vehicles. Now that we’re roughly at the halfway point for the 2015 goal, what is the scorecard?
It’s important to note that the goal was rather naively – or perhaps intentionally – based on manufacturer- and media-supplied data on how many electric cars could be built and not from projections of how many people would actually buy them. Unless we’re talking very hot-selling items like the latest Apple iPhone or iPad, sales projections are usually based on projected sales and not made on potential production.
The estimate actually projected 1,222,200 EV units produced including 13,000 commercial vehicles (Ford Transit Connect, Navistar eStar EV, and Newton EV). Another 252,000 included Fisker Karma and Nina models and the Think EV). Think is no longer producing cars and Fisker Automotive has ceased production, although it should reappear because of it's just-announced bankruptcy sale to China's Wanxiang Group..
Sales of the four EVs and PHEVs to date have been far lower than their target numbers, with the Tesla S a lone exception. The million EV goal looks far from being achievable by 2015.
Electric vehicle models not included in President Obama’s estimates, but now on sale, are the Mitsubishi i-MiEV, Honda Fit EV, Fiat 500e, Chevrolet Spark EV, Toyota RAV4 EV, and smart electric drive. Of these, only the i-MiEV is available everywhere in the country. Some others can be considered ‘compliance vehicles’ since they are only offered in very limited ways with the intent to comply with California’s ZEV mandate, which aims at putting over 1.4 million zero emission vehicles on the road by 2025.
Part of the government’s strategy to reach this goal is to offer substantial tax credits to encourage sales. Typically, this includes a federal credit of $7,500 plus state incentives. As of November 2013, 40 states and the District of Columbia have monetary incentives including electric vehicle tax credits and registration fee reductions ranging from $1,000 in Maryland to $6,000 in Colorado. Even with incentives, though, electric sales are not keeping pace with President Obama’s ambitious goals.

The electric hub motor has been around for a long time. Ferdinand Porsche’s first automobile in 1898 was the Lohner-Porsche with two electric motors in the front wheel hubs. Initially, electricity was supplied from batteries and later by batteries and a gasoline engine-driven generator, in what is considered the first hybrid electric vehicle. While there has been on-and-off interest in hub drive systems, there are currently two programs underway that could lead to production vehicles within a couple of years.
One of the big challenges has been the substantial unsprung weight that can degrade ride quality and handling. This can be overcome by lighter weight motors and other components that are now available. For example, Ford has shown its Fiesta eWheelDrive prototype developed with Schaeffler Technologies in Germany. The two Schaeffler eWheelDrives are housed within the 16-inch rear wheel rims. Each highly-integrated wheel hub drive contains an electric motor, power electronics, controller, brake system, and liquid cooling system.
Each motor supplies a peak 54 horsepower or 44 horsepower continuous output to a rear wheel. The motor produces 516 lb-ft of torque. The highly-integrated wheel hub drive has a total weight of 117 pounds, only 17.6 pounds more than a conventional wheel including its wheel bearing and brake components.
The Fiesta eWheelDrive installation is just a technology demonstrator. Ford and Schaeffler feel the ideal application is in city cars for use in crowded urban areas with limited parking. Everything, with the exception of batteries, needed to propel and brake the car is located in the wheel. Thus, the space now needed for the engine and transmission or electric motor in an EV can be used for passengers and luggage. Indeed, it could mean a four-person car that takes up no more parking space than a current two-person car. The eWheel- Drive steering system could even allow moving sideways into parking spaces.
Despite its somewhat higher wheel-sprung masses, extensive testing has shown the Fiesta eWheelDrive exhibiting driving behavior equal to a conventional Fiesta in terms of comfort and safety. The two wheel hub drive motors also allow torque vectoring for enhanced maneuverability in tight spaces. Ford, Schaeffler, and other partners plan on producing two more drivable vehicles by 2015.
Protean Electric, based in Britain, has been developing hub drive motors for years and plans volume production of its Protean Drive system in China this year. It showed its in-wheel electric drive system on a BRABUS hybrid vehicle at Auto Shanghai 2013. The BRABUS Hybrid, based on the Mercedes-Benz E-Class, is powered by an internal combustion engine driving a generator and two Protean electric drive motors, one in each of the rear wheels. Protean had also demonstrated Protean Drive in a Vauxhall Vivaro cargo van, Guangzhou Trumpchi sedan, Ford F150 pick-up, and a BRABUS full electric vehicle also based on the Mercedes-Benz E-Class.
The Protean PD18, designed to fit inside an 18 x 18 inch wheel rim, provides 735 lb-ft torque and 100 horsepower. This is a 25 percent increase in peak torque compared with the previous generation design. Thus, it is powerful enough to be the only source of traction drive in electric vehicles. The unit only weighs 68 pounds per motor.
Each Protean Drive has a built-in inverter, control electronics, and software. The design can be used in small- to full-size vehicles including application in current vehicle platforms, retrofits to existing vehicles, or in all new vehicles. Protean says it recoups up to 85 percent of the available kinetic energy during regenerative braking. Compared to other electric vehicle drive systems, in-wheel motors apply regenerative braking directly at each wheel independently, similar to standard friction brakes.
Opportunity charging can be a pretty big deal to electric car owners. Topping off at public charging stations, or for that matter at chargers available at the workplace, can considerably extend electric driving range. This can help relieve range anxiety or simply deliver the additional battery power needed for longer drives. But this strategy depends on a charger being available.
For years, EV owners have expressed frustration whenever drivers of internal combustion engine (ICE) vehicles park in an EV charging spot, thus blocking access to a charge. There’s even a term for it – being ‘ICEed.’ Now there’s a new twist. With the number of electrics on the road far surpassing the number of public or workplace chargers, EV owners are now squabbling among themselves as they jockey for their position at an available charger. Enter a new term – ‘charge rage.’
That’s what’s happening when an EV owner sees another EV at a charger and believes it has already topped off and is now simply hogging the charging opportunity. Or charge rage could also occur when an EV driver really needs a charge to get to where they need to go, and other EVs are simply plugged in and an obstacle to their mobility. What’s happening is frustration, unkind words, and often enough one EV owner unplugging another’s car so they have access to a charge.
There’s no easy to answer to this other than a huge infusion of new chargers. There’s movement by some charging manufacturers to institute a charge reservation program. Some companies are also taking reservations for workplace charging, encouraging EV owners to unplug and move out of a charging space once they’re adequately topped off. There is no instant answer. What there is, simply, is a challenge that has not been adequately considered. It will be interesting to watch this unfold.
VW’s e-Golf is coming to U.S. highways at the end of this year and will be available in select states. Powered by a 115 horsepower permanent magnet AC electric motor developing 199 lb-ft torque, the e-Golf is said to accelerate from 0-62 mpg (0-100 km/h) in about 10.4 seconds and offer an electronically limited 87 mph top speed. Driving range should vary between 70 to 90 miles depending on driving habits and environmental conditions.
The e-Golf’s lithium-ion battery is integrated in the center tunnel and within a space-saving frame in the vehicle floor beneath the front and rear seats. The battery accounts for 700 pounds of the e-Golf’s 3090 pound curb weight. Charging with a 120 volt outlet is accomplished in about 20 hours, although a 220 volt garage or public charger will bring the batteries to a full state of charge in less than four hours. Rapid charging at a fast-charge station could bring the e-Golf to 80-percent of charge in 30 minutes.
We are all enamored by the advanced technologies at work in vehicles today. And why wouldn’t we be? The incredibly efficient cars we have today, and the even more efficient models coming in the years ahead, are testament to a process that combines ingenuity, market competitiveness, and government mandate in bringing ever more efficient vehicles to our highways.
It’s been a long and evolutionary process. I remember clearly when PZEV (Partial Zero Emission Vehicle) technology was first introduced in the early 1990s, a breakthrough that brought near-zero tailpipe emissions from gasoline internal combustion engine vehicles. That move was led by Honda and Nissan, with others quickly following. Then there were the first hybrids – Honda’s Insight and Toyota’s Prius – that arrived on our shores at the end of that decade. Both technologies brought incredible operating efficiencies that drastically reduced a vehicle’s emissions, increased fuel economy to unexpected levels, or both.
Of course, there were first-generation battery electric vehicles in the mid-1990s that foretold what would become possible years later. That first foray into EV marketing was deemed by many a failure, yet it set the stage for the advanced and truly impressive EVs we have today. Those vehicles may not yet be cost-competitive with conventionally powered vehicles due to very high battery costs, but that doesn’t diminish the genius engineering that’s brought them to today’s highways.
Even conventionally-powered cars today are achieving fuel efficiency levels approaching that of more technologically complex hybrids. Who would have imagined popular cars getting 40 mpg or better, like the Dodge Dart, Chevy Cruze, Mazda3, Ford Fiesta, and many more in a field that’s growing ever larger each year?
VW and Audi have proven that clean diesel technology can also achieve 40+ mpg fuel efficiency while providing press-you-back-in-your-seat performance, and importantly, doing this while meeting 50 state emissions criteria. That’s saying something considering diesel has historically had a tough go of it meeting increasingly stringent emissions standards in California and elsewhere. Yet, with elegant engineering by these automakers and their diesel technology supplier Bosch – plus this country’s move to low-sulfur diesel fuel late last decade – ‘clean’ diesel was born.
I would be remiss if I didn’t mention natural gas vehicles. There was a time when quite a few automakers were exploring natural gas power in the U.S., but that faded and left Honda as the lone player in this market with its Civic Natural Gas sedan. Now others are joining in with dual-fuel natural gas pickups and vans, benefitting from advanced engine technologies, better natural gas tanks, and a sense that with increasing natural gas reserves in the U.S., demand for natural gas vehicles will grow. As Honda has shown with its Civic, it’s possible to operate on this alternative fuel while also netting admirable fuel efficiency.
All this advanced powertrain technology is important. It makes air quality and petroleum reduction goals achievable, even ones like the ethereal 54.5 mpg fleet fuel economy average requirement that looms for automakers by 2025. There’s no doubt that advanced technologies come at a cost and reaching a 54.5 mpg average will require the full range of efficiency technologies available, from better powerplants and transmissions to greater use of lightweight materials, aerodynamic design, and answers not yet apparent. But I’m betting we’ll get there in the most efficient way possible.

Batteries remain the electric car’s most pervasive challenge. After decades of research and development plus billions of dollars of investment, an energy-dense and affordable electric car battery remains elusive. Automakers are acutely aware of this as high battery costs can mean significant losses on every unit sold.
Ford is aiming to meet the challenge head-on with a new $8 million battery lab that’s now operating at the University of Michigan. The goal is to develop smaller and lighter batteries that are also less expensive to produce, resulting in more efficient and affordable battery electric vehicles with greater driving range.
The automaker’s existing battery labs focus on testing and validating production-ready batteries. This new effort will address batteries earlier in the development process, serving as a stepping-stone between the research lab and the production environment. The new lab includes a battery manufacturing facility supporting pilot projects, testing, and state-of-the-art manufacturing to make test batteries that replicates the performance of full-scale batteries.
Battery development is in its infancy and this kind of research is critical, says Ford, as is the need for new chemistries to be assessed in small-scale battery cells that can be tested in place of full-scale production batteries, without compromising test results. The automaker points out that in the span of 15 years, the industry has gone from lead-acid to nickel-metal-hydride to lithium-ion batteries, and it’s too early in the battery race to commit to one type of battery chemistry.
The long-awaited 2014 Cadillac ELR will emerge early in 2014 at a cost of $75,995, appropriate for high-end luxury cars but no doubt a bit steep for many looking forward to a step up from Chevy’s Volt. Still, there’s a lot here to justify the cost. Featuring a dramatic design and luxury touches throughout, this extended range electric coupe surrounds driver and passengers with handcrafted leather, authentic wood grain, and chrome trim. A Cadillac driving experience is promised as a matter of course.
Powering the ELR is electric drive energized with a T-shaped, 16.5 kWh lithium-ion battery pack. All-electric drive is good for about 35 highway miles, although that’s dependent on driving conditions. After that the ELR’s 1.4-liter gasoline engine-generator produces electricity to power the car over 300 total electrically-driven miles. When operating on battery power the car is expected to offer 82 MPGe fuel efficiency.
Among its many standard features are Cadillac CUE with Navigation displayed via an eight-inch capacitive-touch screen, LED exterior lighting, Lane Departure Warning, Safety Alert Seat, and Forward Collision Alert. A driver can temporarily generate electrical energy from the ELR’s forward momentum via a Regen on Demand feature controlled with steering-wheel paddles.
Four driving modes include Tour, Sport, Mountain, and Hold. Tour is the default mode while Sport offers a more responsive driving experience. Mountain mode maintains battery charge in hilly terrain. Hold mode allows selecting when to use battery power or the ELR’s gas-powered generator.
Lithium is a key component of lithium-ion battery packs that power electric vehicles (EVs) and hybrid vehicles. A recent report from Pike Research forecast global sales of EV charging equipment will grow from 200,000 units sold in 2012 to nearly 2.4 million in 2020, representing a compound annual growth rate of 37%. With lithium a key component to the electric vehicle market, it is crucial that North America has adequate access to this critical element minus any geopolitical conflicts.
Credit Suisse has forecast a 10.3 percent annual growth in demand for lithium between 2009 and 2020. Global lithium demand has tripled over the past decade, and the global market price of lithium carbonate has tripled since 2001 to its current level of around $6,500 per ton.
An industrial research report by David & Company forecasts that the global market for lithium-ion batteries will increase to $43 billion by 2020 compared to an $11 billion level in 2010 with the primary catalyst the increased demand for electric cars.
Most lithium today is mined in Australia, Argentina, and Chile. The largest known deposit is in Bolivia but political turmoil has hampered production. In the United States, there is a Nevada mine with geo-thermal powerplants that extracts lithium as a by-product near the Salton Sea in Southern California. China remains the leading importer of lithium minerals and compounds and the leading producer of value-added lithium materials. My company’s 100 percent-owned Rose Tantalum-Lithium Project, in the James Bay region in Quebec, is slated to start production by 2014 and is free of any geopolitical turmoil. We will be a valued global source for conflict-free Tantalum.
High purity lithium is required for a variety of electrical storage needs – from batteries that power electric and hybrid vehicles or provide large scale storage of renewable and conventionally produced power, to the batteries that power electronics including those found in smart phones, laptops, and gaming systems. Having proven a purity of 99.9 percent for our lithium makes our Rose Tantalum-Lithium project one of only five deposits globally that meet the rigorous specifications for lithium-ion batteries.
It is clear we have to ensure that North America does not lose the global war on being the leader in green energy solutions, which includes access to high quality conflict-free lithium. The war of the new millennium is being fought on a monetary and labor scale across the globe, with China the market leader for rare earth metals with about 97% of the world’s supply.
Next on China’s plate is renewable energy integration. Ironically, as environmental pollution in the People’s Republic of China runs rampant, the country has steadfastly focused on securing leadership status in the renewable industry. The Chinese government has set a goal of China securing 11.4 percent of its energy from non-fossil sources by the end of 2015, up from 8 percent today.
The U.S. government’s commitment to supporting both the renewable energy and electric vehicle industries underlines the need for the rapid development of rechargeable batteries, and this has thrown the spotlight on domestic lithium supplies.
It is critical that North Americans understand the importance of assuming a leader stake in the alternative energy market. As my company possesses the key critical elements crucial to the electric battery sector, we are committed to being an active and valued voice in implementing change.

BMW is planning to offer the i series of electric, plug-in hybrid, and range-extended electric vehicles beginning in late 2013. This entirely new model line will offer BMW’s usual focus on premium engineering and style, but critically, it will also feature a consistent focus on eco sustainability and urban living. BMW is serious enough about this to have worked with New York University to develop a report, ‘Urban Mobility in the 21st Century.’ The report finds that 80 percent of us drive less than 50 miles per day, and that by 2050 the world’s urban population will grow by 80 percent, from 3.5 billion to 6.3 billion. In short, BMW thinks we need cars that work in megacities and also don’t pollute.
The large volume, five-door i3 hatchback will be constructed of lightweight carbon-fiber reinforced plastic containing the i series ‘life’ passenger cell and ‘drive’ electric propulsion cell, powered by a 170 hp electric motor driving the rear wheels. A range-extender engine will be optional. In a departure for BMW, the i3 will have rear ‘coach doors’ hinged at the rear of the doors rather than the front, plus bench seats to make city living (and parking) easier.
The seductive, two seat i8 coupe/cabriolet combines the same lightweight engineering with a 131 hp electric motor driving the front wheels and a 223 hp, 1.5-liter 3-cylinder turbo gas engine at the rear. These powerplants can be used together or separately. The car’s combined 354 horsepower accelerates the i8 from 0 to 60 mph in under six seconds. The i8 also features an electric-only range of 20 miles, a top speed of 155 mph, and up to 80 mpg.
BMW’s long-term mobility plan seems a good one. It integrates lessons learned from data gleaned from its extensive Mini-E and ActiveE electric vehicle field trials and focuses on sustainable manufacturing, practicality, and pollution reduction in an entirely new series of vehicles. BMW’s new i series could be poised to make a huge impact on how electric vehicles are designed and built.
Automotive supplier Visteon is among many companies that clearly understand the importance of advanced electronics in future automobiles. The firm recently illustrated this with its e-Bee concept car that envisions mobility in the year 2020.
The eBee concept aims to explore new and alternative ways of using a vehicle from private ownership to car sharing and short-term rentals. It’s set up to take advantage of diverse powertrains including electric and hybrid power, using such innovations as an HVAC (heating/ventilation/air conditioning) system integrating smart energy technology to conserve energy. The system includes an electric compressor, interior pre-conditioning to conserve on-board battery power, and a cooled shopping box in the trunk.
The car’s sustainably-designed interior uses bio-based resin, hybrid natural fiber, and recyclable expanded polypropylene materials that address environmental performance and reduce weight.
The real story of the e-Bee is its advanced electronics…and there’s loads of it on board. Its driver interface includes a main display for journey information with two smaller touch screens on either side of the steering wheel, the latter providing vehicle controls and interaction with social connections. A projected head-down display provides driving information. Images from a 180-degree rear-view camera are shown in lieu of a rear view mirror.
Each occupant has a personal headrest-mounted audio system, door-mounted wireless charging bays for their electronics, and door-mounted control modules to adjust individual climate zones. User preferences stored in the Cloud set a driver’s preferences upon entry, defining the look and layout of the car’s displays and interior colors.
Clip-on modules like cup holders, cameras, and wireless charging devices – known as 'physical apps' – can be added by users to fit their needs and style sensibilities as desired.
How to extend the range of battery electric vehicles? A start-up company in Stuttgart, Germany has developed an answer in the form of the ‘ebuggy,’ a trailer carrying a lithium-ion battery designed to be towed behind an EV.
The ebuggy is viewed as an ‘on-demand’ solution since an EV would drive on urban trips without the trailer most of the time. Then, for longer trips, the EV would be driven to a service station where the ebuggy would be hooked up to provide extended range. It would be returned to the same service station or dropped off at another station at the destination.
The ebuggy can be towed at speeds up to 62 mph (100 km/hr) and has a four-hour battery capacity, which provides a range extension of about 240 miles for most electric cars. Add the standard range of the EV itself and trips of 300 miles on electricity alone are quite possible.
Envisioning franchised stations that could be co-located with gas stations, garages, or at highway rest stops, ebuggy GMBH says its system requires a much smaller initial investment compared to other range extension ideas like battery exchange stations. Battery recharging can be done using the same equipment used to recharge batteries in EVs. When an electric car owner signs up for ebuggy service, the user gets a kit for upgrading their car to the ebuggy system. This includes a tow hitch, power socket, and in-car display.
General Motor has debuted its first all-electric car since the sporty EV1 that was sold for a time in the 1990s. The Chevrolet Spark EV is basically a Korean-built, five-door Spark subcompact sedan converted into an electric vehicle. However, the drive unit and motor will be assembled at GM’s White Marsh, Maryland manufacturing facility using parts sourced from U.S. and global suppliers.
The Spark EV is powered by a GM-designed, coaxial drive unit and electric motor. Rated at 130 horsepower and 400 lb-ft torque, this motor can accelerate the four passenger EV to 60 mph in under eight seconds. Electric energy is stored in the 20 kilowatt-hour lithium-ion battery. The 560 pound battery pack consists of 336 prismatic cells. It’s warranted for eight years or 100,000 miles. GM has not provided range estimates for the Spark EV, but it is expected to match or exceed that of competitive EVs like the Nissan LEAF and Ford Focus EV, or about 80 miles under real world conditions.
SAE Combo DC Fast Charging will be optional. This will allow the Spark EV to reach 80 percent of full battery charge in as little as 20 minutes in fast-charge mode. A common on-board charging receptacle accommodates all three charging systems – DC Fast Charge, AC 240V, and AC 120V. Using a dedicated 240V outlet, the Spark EV recharges in less than seven hours.
Owners can control charging according to their expected departure time or when electric rates are lowest. Managing and monitoring the vehicle is also possible remotely via computer at OnStar.com, or with a special Chevrolet Mobile App powered by OnStar Remote Link. Drivers can view critical vehicle functions on one of two reconfigurable, high-resolution, seven-inch color LCD screens. Information includes a confidence gauge showing expected driving range based on driving habits and other conditions.
Many external changes are made from the regular Spark to improve aerodynamic efficiency and reduce range-killing drag. The result is a drag coefficient of 0.325 Cd and 2.5 additional miles of range. Low rolling resistance tires add another five to seven miles.
GM says the Spark EV will go on sale in summer 2014. It will initially be sold in California and Oregon, thus at least for now it is considered a ‘compliance’ EV that is being marketed mainly to meet California’s ZEV mandate. The mandate will require 15 percent of cars sold in this state by 2025 to be zero emission vehicles. It will also be available in Canada, Korea, and other global markets. The Spark EV will list for just under $32,500 and qualify for a $7,500 federal tax credit. Even with this incentive, the electric version is nearly double the base price of Chevy’s gasoline-powered Spark. Californians could get an additional $2,000 to $2,500 rebate to help soften the price differential.
BMW’s i3 will roll off the assembly line in late 2013. This will be this automaker’s first production electric vehicle, the culmination of 40 years of development that started with a BMW 1602 that was converted to electric power in 1972. Since then, BMW has developed many electric prototypes and tested several EV fleets under real world conditions. Its electric-specific BMW i brand includes the i3, i8 Coupe, and the i8 Concept Spyder that’s also planned for production.
The latest BMW variant unveiled is the i3 Concept Coupe, a three-door model based on the five-door BMW i3. While riding on the same wheelbase, the coupe has a broader, lower-slung look. It has two individual rears seats and rear windows that are exceptionally large for great visibility. The elimination of the B-pillar makes for easier access to the rear seats as well. According to BMW, the interior illustrates how the i3 cockpit has evolved as it is readied for series production,
Like the i3, the BMW i3 Concept Coupe uses the automaker’s LifeDrive architecture with its Life and Drive modules. The passenger cell forms the core of the Life module and is built from light and strong carbon fiber-reinforced plastic (CFRP). The drive system, chassis, and battery, along with structural and crash functions, are found in the Drive module made mainly of aluminum.
The coupe uses the pure electric version of BMW’s eDrive technology, like the production-ready i3. This means an electric motor developed by BMW that makes 170 horsepower and 184 lb-ft peak torque delivered to the rear wheels via a single-speed transmission. Lithium-ion batteries are located beneath the floor.
A driver can chose between COMFORT, ECO PRO, and ECO PRO+ modes. Sportiness and comfort are best experienced in the standard COMFORT setting. ECO PRO modifies accelerator mapping so the same pedal travel delivers less power, providing more economical energy management and up to 20 percent better driving range. Heating and air conditioning are also switched to a more energy-efficient mode.
Maximum efficiency and range comes in the ECO PRO+ mode. Besides revised accelerator mapping, top speed is limited to 56 mph (90 km/h) and heating and air conditioning are run at minimum levels. Seat heating, mirror heating, and non-essential components of the daytime running lights are switched off. The BMW i3 Concept Coupe has a nominal range of 100 miles (160 kilometers).
The i3 Coupe navigation system features BMW i ConnectedDrive services tailored specifically for EVs. For example, battery charge status, driving style, electric comfort functions, and the selected driving mode – ECO PRO or ECO PRO+ – are taken into account along with the route’s topography and current traffic conditions. The system can make allowances for the extra energy needed for upcoming hills, stop/start traffic, or traffic jams. The most efficient route is shown as an alternative to the fastest. If necessary, the Range Assistant will recommend changing to ECO PRO or ECO PRO+ mode to increase range.
A driver is informed if his destination is within the vehicle’s range and is advised where to recharge. Shortly before arrival at the destination, charging stations in the vicinity are displayed and the driver can reserve one of them. The system presents charging time required before commencing the return trip or driving to the next destination. A smartphone app with an eRemote function developed by BMW ConnectedDrive for the BMW i also offers this information away from the vehicle.
Mitsubishi’s recently-unveiled Outlander plug-in hybrid electric vehicle (PHEV) is a first for this automaker, combining mainstream sport-utility appeal with advanced, plug-in hybrid efficiency. The Outlander PHEV promises drivers the flexibility of an affordable and spacious sport utility that can run in quiet, zero-emission electric mode for commuting, then turn around and handle weekend getaways for five with the cruising range of a conventional SUV. It builds upon the electric drive technology developed for the automaker’s all-electric i-MiEV.
The model’s all-new drivetrain includes a 2.0 liter gasoline engine-generator up front and 80 horsepower electric motors front and rear, with both motors connected to Mitsubishi’s Super All-Wheel Drive Control system. Motors are powered by a 12 kWh lithium-ion battery pack that can be charged in four hours with a conventional 240 volt charging station or just 30 minutes with a quick charger.
What’s most interesting about the Outlander PHEV is how it seamlessly combines smart fuel efficiency and utility. Mitsubishi offers Eco, Normal and Battery Charge driver selectable modes, which focus on maximizing EV time, normal driving, or having the gasoline engine function mainly as a generator to keep the battery charged.
Depending on the state of battery charge, drive mode, and conditions, the integrated management system will automatically choose electric-only, series hybrid, or parallel hybrid mode. In series mode the gasoline engine charges the battery and the vehicle runs on the electric motors, but in parallel mode, like normal hybrids, the gas engine powers the car directly with help from the electric motors. As with other hybrids and EV’s the Outlander generates electricity from both its electric motors during deceleration and regenerative braking.
This new plug-in crossover/SUV offers minimum fuel consumption without sacrificing the four-wheel drive stability or the same dimensions and large 72.6 cubic feet of space that current Outlander owners enjoy (36.2 sq. ft with second row seats up). Gas prices probably aren’t going to be $2.00 any time soon, and customers will always need room to grow. The Outlander PHEV combines real utility with real efficiency. It could be the change that SUVs need.
Based on the Japanese JC08 driving cycle, an electric-only range of 34 miles is estimated with 547 miles achieved on combined gas and electric power. Coming to Japan in early 2013, Outlander PHEV sales will expand to Europe and then the U.S. and elsewhere.
Toyota is now selling its all-new RAV4 EV at select California dealerships. This all-electric SUV was jointly developed by Toyota and Tesla Motors, combining a Tesla designed and produced battery and electric powertrain with Toyota’s most popular SUV model. No interior space was lost due to EV components
Our editors who have driven the RAV4 EV have found it to be an excellent small SUV that performs seamlessly, with an intelligent approach to electric motoring. You’re not left wanting for power, comfort, or the kind of driving experience expected of a Toyota product…it’s all there, but without the inherent drawbacks of burning gasoline. At nearly fifty grand, though, it’s likely not for everyone.
The RAV4 EV’s 154-horsepower AC induction motor drives the front wheels via a fixed-gear, open-differential transaxle. There are two drive modes, ‘Sport’ and ‘Normal.’ In the Sport mode with 273 lb-ft of peak torque brought to bear, the vehicle reaches 0-60 mph in 7.0 seconds and has a top speed of 100 mph. In the Normal mode with 218 lb-ft at the ready, acceleration to 60 mph takes 8.6 seconds and top speed is 85 mph.
Its liquid-cooled lithium-ion battery is a first for Toyota. Battery thermal management systems provide consistent performance in a variety of climates. The battery pack is mounted low and to the center of the vehicle, contributing to a more sedan-like ride. Two charge modes are available, with a Standard Mode charging up to 35 kilowatt-hours for an EPA-estimated range rating of 92 miles, optimizing battery life over range. An Extended Mode charges the battery to its full capacity of 41.8 kilowatt-hours to provide an anticipated range of 113 miles. The battery is warranted for eight years or 100,000 miles.
A drag coefficient of 0.30, the lowest of any SUV in the world, is an improvement over the conventional gas powered RAV4’s Cd of 0.35. To achieve this, Toyota restyled the front bumper, upper and lower grill, side mirrors, rear spoiler, and underbody design to optimize air flow. The Toyota/Tesla designed regenerative braking system increases driving range by up to 20 percent. A tire repair kit replaces the spare to reduce weight.
An innovative climate control system offers three modes. In the NORMAL mode, it operates just like that of a conventional vehicle for maximum comfort, drawing the most power and resulting in the least range. The ECO LO mode balances comfort with improved range through reduced power consumption by the blower, air conditioning compressor, or electric heater. In cold weather, ECO LO automatically activates and controls seat heaters to optimal levels. ECO HI further reduces blower, compressor, and heater levels and also automatically activates the seat heaters as necessary. Efficiency achievements are notable. ECO LO can reduce power consumption by up to 18 percent compared with NORMAL, while ECO HI offers up to a 40 percent reduction. Remote Climate Control – set by a timer, by the navigation display, or by using a smart phone – pre-cools or pre-heats the interior while the vehicle is plugged into the grid to save on-board battery power.
Driving efficiently is assisted with an all-new instrument cluster that includes a power meter, driving range display, battery gauge, speedometer, shift indicator, and multi-information display. The latter has six screens that provide information on driving range, efficiency, trip efficiency, CO2 reduction, and ECO coach and AUX power functions. Trip efficiency displays the average power consumption in intervals of five minutes. Eco coach evaluates the level of eco-sensitive driving according to acceleration, speed, and braking and displays an overall score. CO2 reduction, displayed graphically via a growing tree, is compared to a conventional gasoline vehicle.
Premium Intellitouch Navigation features EV system screens that help maximize driving range. The EV Charging schedule lets customers schedule when the vehicle will charge and activates pre-climate conditioning based on departure time. A Range Map shows how far the car can travel on available battery charge. A Charging Station app displays nearby charging stations.
For the shortest charge time of about six hours, Leviton offers a custom 240 volt, Level 2 charger with 40 amp / 9.6 kilowatt output. The RAV4 EV comes equipped with a 120 volt Level 1 charging cable operating at 12 amps for use when the recommended Level 2 charging is not available.
The RAV4 EV comes standard with the STAR Safety System that includes enhanced vehicle stability control, traction control, anti-lock brake system, electronic brake-force distribution, brake assist, and smart stop technology. While the RAV4 EV is pricy at $49,800, that price decreases a bit since it qualifies for a $2,500 rebate through California’s Clean Vehicle Rebate Program as well as a $7,500 federal tax credit. Toyota plans to sell about 2,600 units through 2014.
