Nissan edges out Tesla for most ZEV credits sold in California

When it comes to California zero-emissions vehicle (ZEV) credits last year, Nissan was selling and Mercedes-Benz was buying. The California Air Resources Board (CARB) put out its ZEV-credits numbers for the year that ended September 30, which is why we now know that Nissan, maker of the battery-electric Leaf, transferred 663.6 ZEV credits out of its account last year. That just edged out the 650.195 credits that Tesla sold. Chrysler's Fiat affiliate was a distant third, but its limited-production Fiat 500E was still able to generate some ZEV credits and then transfer out 235.2 of them. We don't know how much the buyers paid for these credits, since those details are kept private. It's an ever-changing rulebook over at CARB, anyway. On the flip side, Mercedes-Benz had to buy 663.6 ZEV credits in order to comply with clean vehicle-sales mandates in the most populous US state, indicative of the German automaker's gas-guzzling tendencies. Honda has cars that get better fuel economy than your average Benz, but its plug-in vehicles represent just a fraction of total sales and so it had to shell out for 542.5 ZEV credits. Chrysler-Fiat basically tread water, since the 237.8 ZEV credits it required for compliance canceled out gains on the other side of the ledger. Those Dodge Ram pickup trucks don't exactly help matters. Last year, Tesla sold the most ZEV credits while GM purchased the most. Overall, Californians bought about 3.5 million vehicles for the year that ended September 30, including 38,000 battery-electric vehicles, 30,000 plug-in hybrids and 570,000 conventional hybrids. The longstanding ZEV program means that California now has more than 100,000 ZEVs on its roads. Read this for more details on ZEV credit transfers in California.

Nissan will expand free* charging incentive to 25 Leaf markets

Nissan has proof that giving away a bit of electricity makes buying a new Leaf all the more enticing. Thanks to a deal that offers free charging to some Leaf owners in Texas, one dealer there claims his Leaf sales have tripled. We don't see national sales climbing quite that high starting July 1 2014, but an announcement made today at the New York Auto Show will likely give the EV a boost. New Leaf buyers will get to charge for free at public chargers for two years. Within limits: a max of 30 minutes at CHAdeMO and an hour at Level 2 stations. Nissan will expand its "No Charge to Charge" promotion to at least 25 markets across the US. The deal means that new Leaf buyers will get to charge for free at public chargers that accept the new EZ-Charge card, within limits. That means a maximum of 30 minutes at CHAdeMO DC fast chargers and just one hour at Level 2 stations, Brendan Jones, director of Nissan EV infrastructure strategy and development, told AutoblogGreen. This should be plenty of time, Jones said, since the average Leaf driver comes to a CHAdeMO station with 35-40 percent state-of-charge on the battery and the average time they stay is around 16-17 minutes. A half hour is fine at a fast charger, since the battery will get to 80 percent full within that time, but we're less impressed with the one-hour limit at a Level 2 station, since that will only put maybe 20 miles into the battery. The EZ-Charge card is compatible with four of "the leading EV charging networks," which here means ChargePoint, Blink, AeroVironment and NRG eVgo. Nissan says the 25 markets make up over 80 percent of all the US Leaf sales. Anyone who buys a new Leaf in one of the specified markets - or bought one on or after April 1 of this year - will get the free-to-use EZ-Charge card (others can still get the card, which means only carrying one charger company fob instead of four). The promotion starts July 1 in 10 markets (San Francisco, Sacramento, San Diego, Seattle, Portland, Nashville, Phoenix, Dallas-Fort Worth, Houston and Washington, DC) and then expands to the next 15 by the end of June, 2015. Nissan would not specify which markets these will be, but they will be where the Leaf is selling well and there are DC fast chargers. That means, we suspect, places like Chicago, St. Louis, Philadelphia and Atlanta.

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.
