Electrification has not been a primary interest at Mazda. Efficiency? Yes, SKYACTIV technology. Family friendliness? Yep, with four crossover/SUVs of varying stripes. Performance? Well, yeah, Mazdas are fun to drive and the MX-5 Miata is a perennial sports car favorite, plus the brand is competitive in all sorts of racing.

There clearly hasn’t been any urgency to embrace electrification at Mazda, even as most of its competitors have done so. The brand has dabbled, though. There was a Miata EV concept in the 1990s and a short-lived Demio EV demonstration project in Japan back in 2012, but little else. Now things have changed.

Enter the 2022 Mazda MX-30, a model representing the first step in this automaker’s journey toward electrification. Aimed initially at the California market this fall with a likelihood of expanding to other ‘green’ states, the electrified crossover is powered by a 144 horsepower electric motor with 200 lb-ft torque driving the front wheels. Energy is provided by a 35.5 kWh lithium-ion battery. Mazda has not provided U.S. range estimates for its new electric, though the MX-30 is rated at delivering 124 miles of single-charge driving range on the European WLTP testing cycle. Translating that to the more conservative EPA testing cycle is not a science, but you could reasonably conclude that a full battery would deliver about 100 miles of driving on U.S. roads.

Yes, that’s pretty limited range given the direction of new electric vehicle offerings in the U.S., which skew toward 200 miles of driving range or better, courtesy of larger battery packs. Charging via a standard 220-volt wall charger is convenient and assures that when you’re home for the night, just plug in and you’ll have a full charge in the morning. If you’re on the road or just want to pick up additional range while out, plugging into a rapid-charger will bring the battery from 20 to 80 percent charge in about 36 minutes.

Mazda has more in store for the MX-30 beyond this initial all-electric version. Coming later is a range-extended variant featuring the addition of Mazda’s signature rotary engine, with this powerplant operating exclusively as a rotary generator that creates electricity to augment battery power. This, in effect, creates a series-hybrid electric MX-30 with the ability to motor on long after battery power is gone.

Inside the handsome cabin is a floating center console with an electronic shifter and command knob. A 7-inch display is provided and flanked by controls. Adding to the new model’s innovations are rear doors that are hinged at the rear and swing outward at the front.

A handy MyMazda app allows locking doors, monitoring state-of-charge, and adjusting climate controls via a user’s cellphone. A full suite of the automaker’s i-Activsense safety and driver assist systems will be offered, though details about this and the model’s suggested retail price have not yet been revealed.

The MX-30 represents the first of Mazda’s electrification thrust, with a hybrid crossover option coming and a plug-in hybrid variant to be offered in a new large-platform SUV. All promise expected Mazda driving dynamics courtesy of an enhanced SKYACTIVE vehicle architecture. Base price of the MX-30 is $34,645 plus destination charge.

The driving range of electric vehicles is becoming less of an issue as they surpass 200 miles or greater, approaching the distance between fill-ups of some internal combustion engine vehicles…or maybe the bladder capacity of their drivers. However, the time it takes to recharge an EV is still a negative attribute.

Generally, EVs charge at a fairly slow rate. A 240-volt Level 2 home or public charger will charge a Chevy Bolt from depleted to full in about 4 1/2 hours, providing a range of about 238 miles. That’s a far cry from 5 minutes to fill a gas tank. It’s significantly slower when charging a Bolt with a Level 1 charger using a household’s standard 120-volt power since this adds only about 4 miles an hour!

Of course, charging companies and automakers are working together to expand the small-but-growing network of fast chargers in key areas of the country, allowing EVs to gain up to 90 miles of charge in around 30 minutes. Tesla claims that its Supercharger stations being upgraded to Version 3 can charge a Tesla Model 3 Long Range at the rate of about 15 miles a minute, or 225 miles in just over 15 minutes under best conditions.

If current technology EVs become popular for mid- to long-range travel, gasoline stations, truck stops, and public charging stations equipped with Level 2 and even somewhat faster chargers run the very real risk of becoming parking lots.

When it comes to charging EVs, charging times come down to kilowatts available. The best Tesla V3 charger is rated at 250 kilowatts peak charge rate. Now, much research is being done here and in other countries on what is called Extreme Fast Charging (XFC) involving charge rates of 350-400 kilowatts or more. The U.S. Department of Energy is sponsoring several projects aimed at reducing battery pack costs, increasing range, and reducing charging times.

There are several challenges for XFCs. First, when lithium-ion (Li-ion) batteries are fast charged, they can deteriorate and overheat. Tesla already limits the number of fast charges by its standard Superchargers because of battery degradation, and that’s only at 120-150 kilowatts. Also, when kilowatt charging rates increase voltage and/or amperage increases, which can have a detrimental effect on cables and electronics.

This begs the question: Is the current electrical infrastructure capable of supporting widespread use of EVs? Then, the larger question is whether the infrastructure is capable of handling XFC with charging rates of 350 kilowatts or more. This is most critical in urban areas with large numbers of EVs and in rural areas with limited electric infrastructure.

The answer is no. Modern grid infrastructures are not designed to supply electricity at a 350+ kilowatt rate, so costly grid upgrades would be required. Additionally, communities would be disrupted when new cables and substations have to be installed. There would be a need for costly and time-consuming environmental studies.

One approach being is XFC technology being developed by Zap&Go in the UK and Charlotte, North Carolina. The heart of Zap&Go's XFC is carbon-ion (C-Ion) energy storage cells using nanostructured carbons and ionic liquid-based electrolytes. C-Ion cells provide higher energy densities than conventional supercapacitors with charging rates 10 times faster than current superchargers. Supercapacitors and superchargers are several technologies being considered for XFCs.

According to Zap&Go, the C-Ion cells do not overheat and since they do not use lithium, cobalt, or any materials that can catch fire, there is no fire danger. Plus, they can be recycled at the end of their life, which is about 30 years. Zap&Go's business model would use its chargers to store electric energy at night and at off-peak times, so the current grid could still be used. Electrical energy would be stored in underground reservoirs similar to how gasoline and diesel fuels are now stored at filling stations. EVs would then be charged from the stored energy, not directly from the grid, in about the same time it takes to refuel with gasoline.

The fastest charging would work best if C-Ion cell batteries are installed in an EV, replacing Li-ion batteries. EVs with Li-ion batteries could also be charged, but not as quickly. Alternatively, on-board XFC cells could be charged in about five minutes, then they would charge an EV’s Li-ion batteries at a slower rate while the vehicle is driven, thereby preserving the life of the Li-ion battery. The downside is that this would add weight, consume more room, and add complexity. Zap&Go plans to set up a network of 500 ultrafast-charge charging points at filling stations across the UK.

General Motors is partnering with Delta Electronics, DOE, and others to develop XFSs using solid-state transformer technology. Providing up to 400 kilowatts of power, the system would let properly equipped electric vehicles add 180 miles of range in about 10 minutes. Since the average American drives less than 30 miles a day, a single charge could provide a week’s worth of driving.

The extreme charging time issue might be partly solved by something already available: Plug-in hybrid electric vehicles (PHEVs). As governments around the world consider banning or restricting new gasoline vehicles in favor of electric vehicles, they should not exclude PHEVs. Perhaps PHEVs could be designed so their internal combustion engines could not operate until their batteries were depleted, or their navigation system determines where they could legally operate on electric or combustion power.

It’s looking like Tesla doesn’t have a lock on the fast-charging that encourages longer-distance electric vehicle journeys. While clearly in catch-up mode, a number of automakers are partnering with charging providers to install fast-charge stations at key points along major transportation routes. The latest is a partnership between Nissan and EVgo that will enable rapid charging at strategically located stops between Boston and Washington DC.

The 'I95 Fast-Charge ARC' (Advanced Recharging Corridor) will include nine charging sites along 500 miles of Interstate 95 with a total of 50 DC fast-chargers, each offering two fast-charge plugs each. Since technology marches on, the stations will have a capability of charging four or more EVs simultaneously at a power output of 50kW, with pre-wiring to enable easy upgrades for charging at up to 150kW once the technology is available consumer stations.

The Boston-DC project follows a similar project in California. With construction already underway, completion is expected in time for the launch of the all-new Nissan LEAF.

Expanding the driving range capabilities of electric cars through fast charging is of growing interest. Tesla has keyed in on this with its high-profile Supercharger network of fast chargers along major transportation corridors. While this is great for Tesla owners, it’s not a comfort to drivers of other EVs since the SuperCharger network is not compatible with their cars.

Enter ChargePoint, VW, and BMW, which have joined together to offer similar capabilities for other electric vehicle models. The three are developing express electric vehicle charging corridors with fast charging stations that allow EV drivers to recapture up to an 80 percent charge in just 20 minutes. Fast charging sites will be strategically spaced no more than 50 miles apart to make longer trips possible for EVs that incorporate a DC fast charging capability.

Initial efforts will focus on heavily-traveled routes on the East and West Coasts, providing 100 DC fast chargers at existing ChargePoint sites. The aim is to expand fast charging capabilities to other sites within the ChargePoint network, which already offers more than 20,000 charging spots in North America. EV drivers can access the network with a ChargePoint or ChargeNow card or with the ChargePoint mobile app.
