Mitsubishi, Nissan will build mini EV together

That minicar project that erstwhile competitors Nissan and Mitsubishi launched about four years ago is about to go a little more maxi. NMKV Co., the joint venture established in June 2011 by the two Japanese automakers to make minicars, is going to get more resources specifically to ease a move into the electric-vehicle sector. Specifically, Nissan, which makes the all-electric Leaf, is going to have a bigger role in the testing, design, and development of the partnership's mini EVs. A memorandum of understand between Nissan and Mitsubishi, maker of the i-MiEV, is in the works. So far, the joint-venture has sold about 500,000 gas-powered three-cylinder compact vehicles under the two automotive brands, so it must be doing something right. The first Nissan Dayz and the Mitsubishi eK Wagon models started production in 2013. Sales of the Nissan Dayz Roox and Mitsubishi eK Space, which went the higher-roof route, began early last year. Nissan and Mitsubishi started making noise about this last summer, when word came out that the little EV may be priced at less than $15,000 in Japan, quite a bit cheaper than either the Leaf or the i-MiEV over there. As with the current models, the future minicar variants will be produced at Mitsubishi's Mizushima factory in Japan. So far, the partnership would only say that details about NMKV's next-generation mini EV will be released "at a later time," so specifics like range and other performance measures will have to wait. Until then, you can take a look at NMKV's press release below. Nissan, Mitsubishi Motors and NMKV reach agreement on planning and development of next-generation minicars Nissan Motor Co., Ltd., Mitsubishi Motors Corporation, and their joint venture NMKV Co., Ltd. today reached an agreement to continue their joint project regarding development of the next generation of current minicar models. The three companies will soon sign a memorandum of understanding. The companies aim to develop more competitive products by optimizing resource allocation and their respective roles and responsibilities. Nissan will be more deeply involved in development operations, such as design development and testing. In addition to its product planning and project development roles, NMKV will strengthen its management capabilities by adding a new department to enhance collaboration with engineering and manufacturing functions. Vehicle production is planned to continue at Mitsubishi's Mizushima Plant.

Recharge Wrap-up: drifting Nissan Leaf video, BMW i sponsors Formula E Berlin ePrix

Watch a Nissan Leaf drift. The folks at Autocar got their hands on Nissan's otherwise tame electric vehicle with a set of plastic rear tires, and got it sideways at the British Drift Championship. If that sounds ridiculous, well, it is, but it's also enormously entertaining. If it sounds particularly tricky to pull off in the front-drive EV, yeah, it's that, too. Check it out the drifting Leaf in the video above, and read more commentary at Hybrid Cars. BMW's i division is the title sponsor of the 2016 Formula E Berlin ePrix. The German automaker, which has already put the i8 and i3 to work as safety and medical cars for the electric racing series, is "delighted to be prominently represented with BMW i at the race weekend in the German capital," according to Joerg Reimann, BMW's Vice President of Brand Experience. The 2016 FIA Formula E BMW i Berlin ePrix - as it is now officially titled - takes place on May 21. Read more from Formula E. A Hawaiian biodiesel plant is the first in the US to be certified as sustainable. Pacific Biodiesel's Big Island Biodiesel plant gets its certification from the Sustainable Biodiesel Alliance, covering both the plant's production and distribution of the alternative fuel. The facility uses waste oil, including used cooking oil, to produce its fuel. The certification system is designed to help worthy biofuel producers show that their processes and products are more than just greenwashing. Read more at Utility Dive, or from The New York Times. India's KPIT Technologies has earned the Promising Innovation in Transport Award at the 2016 Summit of the International Transport Forum in Leipzig, Germany. KPIT earned the special recognition for its system to convert diesel buses to all-electric power. The company's retrofits can be applied to a wide variety of bus platforms.

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.
