It seems we’re well past the tipping point for electric cars now, 25 years after GM’s groundbreaking but short-lived EV1 electric car made its way to the highway. Back then, after daily life with an EV1 during a year-long test and then watching it sadly leave on a flatbed for parts unknown, I knew well the future potential that modern electric vehicles would hold. In the decades since then, automakers have committed to huge investments in expanding their electric vehicle offerings, suppliers have stepped up with new innovations, and consumers are now interested like never before. Plus, of course, some serious government regulation and incentives are driving the electric car field ahead in ways that only government can.
But there are challenges ahead. It isn’t enough that far better electric cars are being built today with compelling features, attractive designs, and desirable performance and range. Many other elements must fall into place for electric vehicles to become the success story we all hope will come to pass, so addressing key inhibitors of an electric feature is crucial. Let’s take a look at the top 5 reality checks that are top-of-mind.
Back in the 1990s when there was great excitement at the prospect of electric cars, there were also big questions. There was no battery front-runner, though there were many technologies and chemistries at play including advanced lead-acid, nickel cadmium, nickel-metal-hydride, sodium-sulfur, sodium-bromine, zinc-air, lithium-ion, and more. Still, choices had to be made so EV programs could move forward. Ultimately, advanced lead-acid won out for small vehicle programs and the first generation of GM EV1s, followed by better and more energy-dense electric car batteries like nickel-metal-hydride and lithium-ion.
Today, nickel-metal-hydride and lithium-ion batteries are primarily used for hybrid, plug-in hybrid, and battery electric vehicles. Lithium-ion, or one of its cousins like lithium-polymer, is used for electric vehicles due to its greater energy density and thus longer driving range. However, lithium batteries are costly and additional challenges remain.
Of great concern are instances of thermal runaway issues and a limited number of spontaneous vehicle fires caused by lithium-ion batteries. Some Teslas have suffered from such battery fires, and GM can certainly attest to this unexpected challenge since it has been involved in a recall of all Chevy Bolt EVs made due to potential fire issues, to the tune of about $1.8 billion. Hyundai went through its own recall with the Kona EV for similar issues with its batteries.
Battery technology continues to improve and costs have gravitated downward in recent years, making the cost of building electric vehicles more reasonable, though still considerably higher than building internal combustion vehicles. Yes, there are substantial cost savings realized by owning and driving an electric vehicle. But to truly be a success, at some point there must be truly affordable electric vehicles for everyone to buy, and battery safety issues must be fully resolved.
The ideal location for electric vehicle charging is at home with a 220-volt Level 2 wall charger. All mainstream electric vehicles support this type of charging, plus significantly slower charging with a portable ‘convenience’ charger plugged in a standard 110-volt household outlet.
Charging up with a 220-volt wall charger is convenient and efficient, with a full charge typically coming in about 2 to 10 hours, depending on the vehicle being charged and the battery’s energy level when you plug in. Simply, if your battery shows 40 miles of range left, it will take considerably longer to fully charge than if 140 miles of range is shown. For convenience, electric vehicle owners typically plug in at home during the evening so there’s a fully-charged EV waiting for them in the morning.
EV owners living in apartments, condos, and elsewhere – including dense urban areas where there may be no garage – need other solutions. To a limited degree, this is being addressed with pay-for-use chargers in common areas or even dedicated outside chargers at assigned parking spaces. Public chargers are also being installed in increasing numbers in urban developments as part of a growing public charging network. In addition, the number of chargers provided at the workplace is seeing greater interest, allowing EV owners to energize their batteries while parked at work.
Charging away from home is becoming easier with a significant expansion of a public charging network by companies like Electrify America, ChargePoint, Blink Charging, EVgo, SemaCharge, Volta, and Tesla. Still, this is a relatively nascent effort with charging opportunities far eclipsed by the abundant and convenient opportunities to refuel gasoline vehicles. Plus, to offer the kind of charging most meaningful to drivers, public chargers must ultimately offer fast-charge capability that enables gaining an additional 80 or 100 miles of range in just 20 to 30 minutes, if an EV is fast-charge capable. This network is growing but far from adequate, especially if it’s to keep pace with the large number of electric vehicles coming to our highways. Building out a nationwide network of fast chargers is costly since the investment for each is in the neighborhood of $100,000.
Many electric vehicle enthusiasts and electric utilities are quick to point out that our existing electrical grid can adequately handle the charging needs of millions of EVs on the road. We’re not so sure. Plus, if the aspirations of EV enthusiasts come to fruition, there will be many more than just a few million EVs on the road in the future.
For years, certain areas of the country have experienced power outages as electricity demand outpaced grid capacity. Heat waves exacerbate this as air conditioning use soars, something made even worse in recent times with record-setting temperatures attributed to climate change. Given the trends pointed out by climate experts, these extraordinary heat waves are likely to increase.
To this point, the California Independent System Operator, which manages electricity delivered through California’s long-distance power lines, issued multiple Flex Alerts last summer. The Flex Alerts included a request for EV owners to charge in the morning and early daytime hours to avoid placing additional load on an already-overtaxed grid. While that request is counterintuitive to the long-held notion that charging EVs overnight is ideal since electrical demand lessens during overnight hours, it may make sense in a state like California that increasingly relies on renewable power as an important, zero-emission component of electrical generation. Simply, renewables like solar and wind-generated power wane at night.
Another challenge to a future of large-scale electric vehicle charging is the increasing frequency and scope that wildfires pose to the reliable delivery of electricity. In California, a long-time leader in encouraging electric vehicles, this could become a particularly vexing issue as the state continues to battle historic wildfires. Because downed powerlines have sparked numerous catastrophic fires here, the state’s electric utilities can – and have – preemptively initiated Public Safety Power Shutoffs that cut power to regions expected to experience high winds that could cause trees to damage electrical lines. No power, no charging.
Still, this doesn’t mean that an increasingly ‘smart’ grid can’t support large numbers of electric vehicles or that strategic, system-wide upgrades can’t be made to allow the grid to effectively deal with the challenges of wind, wildfires, and climate change. It does mean we should be aware of the potential for problems and make no assumptions, but rather plan far in advance to ensure that electric vehicle charging can be done consistently and won’t overwhelm the nation’s electrical grid in any way.
Electric vehicles remain a very small part of today’s new vehicle market – perhaps 3% or so and growing – for a multitude of reasons. Among these are cost, the perception that a battery electric vehicle may not fulfill a driver’s varying needs, and a general hesitation to embrace what many perceive as an unfamiliar and unproved propulsion technology. When enough of your friends and neighbors are driving electric and others see how well EVs fit their driving needs, that’s all likely to change. But we have a long way to go.
There are more people today than ever who have a decent grasp of electric cars and how they work because of the much greater exposure these vehicles have in the general media. That said, there is a greater percentage that really have no clue. That must change if electric cars are to increase market share to the degree that people want and expect. EV education must happen at all levels, and fast.
New car dealers have a unique opportunity to share knowledge of electric cars with would-be buyers, especially if a dealership is committed to the cause and there’s a knowledgeable EV specialist on hand. While a new generation of automakers aiming to exclusively sell EVs have their educational and outreach strategy down, legacy automakers largely do not. Those coming to dealerships are generally prospecting for a new car purchase or lease, now or later. They want to compare models and features, sit behind the wheel, and take a test drive.
While more electric vehicle product is being offered than in previous years, most buyers will not gravitate toward them naturally. What better opportunity than to encourage a first drive of a new electric model? The experience will be enlightening for those who have never been behind the wheel of an electric, with the seamless driving experience and unexpected performance a likely surprise. Leaving a dealership with a greater understanding of electric vehicles and how they work will return rewards, whether in the short- or long-term.
If you bet everything on a decision that may drive you past the point of no return, is it the right choice? That depends on the outcome, of course. It worked for Kevin Costner’s character Ray Kinsella in the film Field of Dreams, as he literally bet the farm on blind faith that forces beyond understanding would beckon folks to the baseball diamond in his Iowa cornfield. The movie was compelling and its emotional attraction undeniable. So, too, is the prospect of millions of zero-emission electric vehicles plying our nation’s highways.
We were able to relive Field of Dreams in 2021 as the Yankees and White Sox played a real-life game at a Major League Baseball stadium amid the cornfields, next to the Dyersville, Iowa diamond seen in Field of Dreams. And now we’re living with the very real prospect of an electric vehicle future, with many dedicated people, companies, and institutions focused on making it happen. Still, will that brand of faith work for electric cars?
Amid all the challenges, automakers new and old are betting their future – and possibly ours – that it will.
There’s something almost magical about plugging your car into an outlet at night and waking up to a full ‘tank’ in the morning. There’s no need for a stop at the gas station, ever. Plus, there’s no nagging guilt that the miles metered out by the odometer are counting off one’s contribution toward any societal and environmental ills attendant with fossil fuel use.
This is a feeling experienced during the year Green Car Journal editors drove GM’s remarkable EV1 electric car in the late 1990s. Daily drives in the EV1 were a joy. The car was sleek, high-tech, distinctive, and with the electric motor’s torque coming on from zero rpm, decidedly fast. That’s a potent combination.
The EV1 is long gone, not because people or companies ‘killed’ it as the so-called documentary Who Killed the Electric Car suggested, but rather because extraordinarily high costs and a challenging business case were its demise. GM lost many tens of thousands of dollars on every EV1 it built, as did other automakers complying with California’s Zero Emissions Vehicle (ZEV) mandate in the 1990s.
Even today, Fiat Chrysler CEO Sergio Marchionne says his company loses $14,000 for every Fiat 500e electric car sold. Combine that with today’s need for an additional $7,500 federal tax credit and up to $6,000 in subsidies from some states to encourage EV purchases, and it’s easy to see why the electric car remains such a challenge.
This isn’t to say that electric cars are the wrong idea. On the contrary, they are perceived as important to our driving future, so much so that government, automakers, and their suppliers see electrification as key to meeting mandated 2025 fleet-wide fuel economy requirements and CO2 reduction goals. The problem is that there’s no singular, defined roadmap for getting there because costs, market penetration, and all-important political support are future unknowns.
The advantages of battery electric vehicles are well known – extremely low per-mile operating costs on electricity, less maintenance, at-home fueling, and of course no petroleum use. Add in the many societal incentives available such as solo driving in carpool lanes, preferential parking, and free public charging, and the case for electrics gets even more compelling. If a homeowner’s solar array is offsetting the electricity used to energize a car’s batteries for daily drives, then all the better. This is the ideal scenario for a battery electric car. Of course, things are never this simple, otherwise we would all be driving electric.
There remain some very real challenges. Government regulation, not market forces, has largely been driving the development of the modern electric car. This is a good thing or bad, depending upon one’s perspective. The goal is admirable and to some, crucial – to enable driving with zero localized emissions, eliminate CO2 emissions, reduce oil dependence, and drive on an energy source created from diverse resources that can be sustainable. Where’s the downside in that?
Still, new car buyers have not stepped up to buy battery electric cars in expected, or perhaps hoped-for, numbers, especially the million electric vehicles that Washington had set out as its goal by 2015. This is surprising to many since electric vehicle choices have expanded in recent years. However, there are reasons for this.
Electric cars are often quite expensive in comparison to their gasoline-powered counterparts, although government and manufacturer subsidies can bring these costs down. Importantly, EVs offer less functionality than conventional cars because of limited driving range that averages about 70 to 100 miles before requiring a charge. While this zero-emission range can fit the commuting needs of many two-vehicle households and bring substantial fuel savings, there’s a catch. Factoring future fuel savings into a vehicle purchase decision is simply not intuitive to new car buyers today.
Many drivers who would potentially step up to electric vehicle ownership can’t do so because most electric models are sold only in California or a select number of ‘green’ states where required zero emission vehicle credits are earned. These states also tend to have at least a modest charging infrastructure in place. Manufacturers selling exclusively in these limited markets typically commit to only small build numbers, making these EVs fairly insignificant in influencing electric vehicle market penetration.
Battery electric vehicles available today include the BMW i3, BMW i8, Chevrolet Spark EV, Fiat 500e, Ford Focus Electric, Honda Fit EV, Kia Soul EV, Mercedes-Benz B-Class Electric Drive, Mitsubishi i-MiEV, Nissan LEAF, Smart ForTwo Electric Drive, Tesla Model S, Toyota RAV4 EV, and VW e-Golf. While most aim at limited sales, some like BMW, Nissan, and Tesla market their EVs nationwide. The Honda Fit EV and Toyota RAV4 EV are being phased out. Fleet-focused EVs are also being offered by a small number of independent companies. Other battery electrics are coming.
BMW’s i3 offers buyers an optional two-cylinder gasoline range extender that generates on-board electricity to double this electric car’s battery electric driving range. A growing number of electrified models like the current generation Prius Plug-In and Chevy Volt can also run exclusively on battery power for a more limited number of miles (10-15 for the Prius and up to 40 miles in the Volt), and then drive farther with the aid of a combustion engine or engine-generator. Both will offer greater all-electric driving range when they emerge as all-new 2016 models. Many extended range electric vehicles and plug-in hybrids like these are coming soon from a surprising number of auto manufacturers.
It has been an especially tough road for independent or would-be automakers intent on introducing electric vehicles to the market. Well-funded efforts like Coda Automotive failed, as have many lesser ones over the years. Often enough, inventors of electric cars have been innovative and visionary, only to discover that becoming an auto manufacturer is hugely expensive and more challenging than imagined. In many cases their timeline from concept and investment to production and sales becomes so long that before their first cars are produced, mainstream automakers have introduced models far beyond what they were offering, and at lesser cost with an established sales and service network to support them.
A high profile exception is Tesla Motors, the well-funded Silicon Valley automaker that successfully built and sold its $112,000 electric Tesla Roadster, continued its success with the acclaimed $70,000-$100,000+ Model S electric sedan, and will soon deliver its first Tesla Model X electric crossovers. While Tesla has said it would offer the Model X at a price similar to that of the Model S, initial deliveries of the limited Model X Signature Series will cost a reported $132,000-$144,000. It has not yet been announced when lower cost 'standard' Model X examples will begin deliveries to Tesla's sizable customer pre-order list.
Tesla’s challenge is not to prove it can produce compelling battery electric cars, provide remarkable all-electric driving range, or build a wildly enthusiastic – some would say fanatical – customer base. It has done all this. Its challenge is to continue this momentum by developing a full model lineup that includes a promised affordable model for the masses, its Model 3, at a targeted $35,000 price tag. It will be interesting to see if the Model 3 ultimately comes to market at that price point.
This is no easy thing. Battery costs remain very high and, in fact, Tesla previously shared that the Tesla Roadster’s battery pack cost in the vicinity of $30,000. While you can bury the cost of an expensive battery pack in a high-end electric car that costs $70,000 to over $100,000, you can’t do that today in a $35,000 model, at least not one that isn’t manufacturer subsidized and provides the 200+ mile range expected of a Tesla.
The company’s answer is a $5 billion ‘Gigafactory’ being built in Nevada that it claims will produce more lithium-ion batteries by 2020 than were produced worldwide in 2013. The company’s publicized goal is to trim battery costs by at least 30 percent to make its $35,000 electric car a reality and support its growing electric car manufacturing. Tesla has said it’s essential that the Gigafactory is in production as the Model 3 begins manufacturing. The billion dollar question is…can they really achieve the ambitious battery and production cost targets to do this over the next few years, or will this path lead to the delays that Tesla previously experienced with the Tesla Roadster, Model S, and Model X?
Tesla is well-underway with its goal of building out a national infrastructure of SuperCharger fast-charge stations along major transportation corridors to enable extended all-electric driving. These allow Tesla vehicles the ability to gain a 50 percent charge in about 20 minutes, although they are not compatible with other EVs. For all others, Bosch is undertaking a limited deployment of its sub-$10,000 DC fast charger that provides an 80 percent charge in 30 minutes. A joint effort by ChargePoint, BMW, and VW also aims to create express charging corridors with fast-charge capability on major routes along both coasts in the U.S.
The past 25 years have not secured a future for the battery electric car, but things are looking up. The next 10 years are crucial as cost, infrastructure, and consumer acceptance challenges are tackled and hopefully overcome to make affordable, unsubsidized electric cars a mass-market reality. It is a considerable challenge. Clearly, a lot of people are counting on it.
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.
