Nissan considering 200-mile Leaf to take on Chevy Bolt?

With 30,200 units sold, the Nissan Leaf posted its best year ever in the US in 2014. However, Nissan needs to keep looking over its shoulder because the Chevrolet Bolt Concept from the 2015 Detroit Auto Show clearly has success EV in its sights. Chevy claims that for roughly the same price (after incentives) as a Leaf, the future Bolt could offer a 200-mile range. Although, evidence continues to mount that the Japanese brand is hard at work on its next-gen electric hatchback capable of significantly longer driving distances. According to TheDetroitBureau.com, the next Leaf will reportedly debut in about two years and will be offered in a high-output version with 200 miles or more of range. It will all be possible thanks to new lithium-ion batteries with lower weight and higher power density. If accurate, the changes would more than double the model's current EPA-estimated 84-mile range and put the hatchback on sale at roughly the same time as the Bolt's debut, if it happens. "We want to be competitive," said Nissan CEO Carlos Ghosn to TheDetroitBureau.com during the Detroit Auto Show. "It may have even more range." In another speech, he also predicted that the company's EVs would become even more affordable. The statements are hardly a surprise from the company boss. Ghosn is a big proponent of electric power over other zero-emissions alternatives because it is cheaper overall, among other reasons. The latest speculation about battery innovations from the next Leaf actually echoes earlier leaks about the car. Ghosn suggested during a Japanese TV interview that the range could double for the new generation, and an unnamed engineer believed that 250 miles of driving was at least possible.

DC fast charging not as damaging to EV batteries as expected

As convenient as DC fast charging is, there have been lots of warnings that repeated dumping of so many electrons into an electric vehicle's battery pack in such a short time would reduce the battery's life. While everyone agrees that DC fast charging does have some effect on battery life, it may not be as bad as previously expected. Over on SimanaitisSays, Dennis Simanaitis, writes about a recent presentation by Matt Shirk of the Idaho National Laboratory (INL) called DC Fast, Wireless, And Conductive Charging Evaluation Projects (PDF) that describes an ongoing test of four 2012 Nissan Leaf EVs that are being charged in two pairs of two. One pair only recharges from 50-kW DC fast chargers, which the other two sip from 3.3-kW Level 2 chargers exclusively. Otherwise, the cars are operated pretty much the same: climate is automatically set to 72 degrees, are driven on public roads around Phoenix, AZ and have the same set of dedicated drivers is rotated through the four cars. "Degradation depends more on the miles traveled than on the nature of recharging." What's most interesting are the charts on page seven of Shirk's presentation (click the image above to enlarge), which show the energy capacity of each of the four vehicles. When they were new, the four batteries were each tested to measure their energy capacity and given a 0 capacity loss baseline. They were then tested at 10,000, 20,000, 30,000 and 40,000 miles, and at each point, the DC-only EVs had roughly the same amount of battery loss as the Level 2 test subjects. The DC cars did lose a bit more at each test, but only around a 25-percent overall loss after 40k, compared to 23 percent for the Level 2 cars. Simanaitis' takeaway is that, "INL data suggest that the amount of degradation depends more on the miles traveled than on the nature of recharging." The tests are part of the INLs' Advanced Vehicle Testing Activity work and a final report is forthcoming. These initial numbers from IPL do mesh with other research into DC fast charging, though. Mitsubishi said daily fast charging wouldn't really hurt the battery in the i-MiEV and MIT tests of a Fisker Karma battery showed just 10-percent loss over 1,500 rapid charge-discharge cycles.

Car technology I'm thankful and unthankful for

The past few years have seen a surge of tech features in new vehicles — everything from cloud-based content to semi-autonomous driving. While some of it makes the driving experience better, not all tech is useful or well thought out. Automakers who are adept at drivetrains, ride quality and in-cabin comforts often fail at infotainment interfaces and connectivity. From testing dozens of vehicles each year and in the spirit of gratitude, here are three car tech features I'm thankful — and a trio I could live without. Thanks Connected search: This seems like a no-brainer since everyone already has it on their smartphones, but not all automakers include it in the dashboard and as part of their nav systems. The best ones, such as Toyota Entune, leverage a driver's connected device to search for a range of services and don't charge a subscription or require a separate data plan for the car. I also like how systems like Chrysler Uconnect use Yelp or other apps to find everything from coffee to gas stations and allow searching via voice recognition. Apple CarPlay and Android Auto: It took two of the largest tech companies to get in-dash infotainment right. While they have their disadvantages (you're forced to use Apple Maps with CarPlay, for example), the two smartphone-integration platforms make it easier and safer to use their respective native apps for phoning, messaging, music and more behind the wheel by transferring a familiar UI to the dashboard — with no subscription required. Heated seats and steering wheels: I really appreciate these simple but pleasant features come wintertime. It's easy to get spoiled by bun-warmers on frosty mornings and using a heated steering wheel to warm the cold hands. I recently tested a 2018 Mercedes-Benz E400 Coupe that also had heated armrest that added to a cozy luxury experience. Bonus points for brands like Buick that allow setting seat heaters to turn on when the engine is remotely started. No thanks Automaker infotainment systems: Automakers have probably poured millions into creating their own infotainment systems, with the result largely being frustration on the part of most car owners. And Apple CarPlay and Android Auto coming along to make them obsolete. While some automaker systems, such as Toyota Entune and FCA's Uconnect, are easy and intuitive to use, it seems that high-end systems (I'm looking at you BMW iDrive and Mercedes-Benz COMAND) are the most difficult.
