EZ-Charge program will get rolled out for all vehicles [UPDATE]

UPDATE: It appears that Chargepoint has pulled out of the program. It looks like a myriad of vehicles will be eligible for the single-card recharging program under NRG Energy's NRG eVgo division. The EZ-Charge platform that Nissan said last month would allow Leaf owners to use multiple vehicle recharging networks with a single card will soon be offered to other plug-in vehicles. eVgo will start sending out EZ-Charge cards this summer to various markets in Northern and Southern California and Texas as well as the Pacific Northwest, Phoenix, Nashville and Washington, DC. EZ-Charge uses a single card that is good for eVgo stations as well as stations within the ChargePoint, Blink and AeroVironment networks. It will debut in 10 EZ-Charge markets on July 1. By mid-2015, 15 more markets will be added. Nissan announced the 'No Charge to Charge' program last month at the New York Auto Show. Nissan said at the time that Leaf buyers would get two years of free charging, but individual charging sessions were limited to 30 minutes at CHAdeMO stations and an hour at the more-common Level 2 stations. The automaker also estimated that the 25 markets included by next year account for more than 80 percent of US Leaf sales. Take a look at NRG's press release below. NRG eVgo Introduces New Convenience to Electric Vehicle Charging First-of-Its-Kind EZ-Charge All-Access Card gives EV drivers convenience to use chargers from multiple charging providers PRINCETON, N.J.--(BUSINESS WIRE)--This summer, NRG eVgo, a subsidiary of NRG Energy, Inc. (NYSE:NRG), will roll out the EZ-Charge (SM) platform, a first-of-its-kind initiative that will offer electric vehicle (EV) drivers the ability to access multiple EV charging networks with a single all-access card. "For too long, EV drivers have been limited to only the chargers that were in their network meaning they might drive past a number of charging stations in other company's networks before they could get to one they could use with their current provider" The EZ-Charge platform will enable drivers of any electric car make or model to carry a single access card for charging on multiple networks, much like consumers today carry a single credit card to access multiple retailers.

Nissan wants an American driver for its Le Mans team

"We'll use every driver development tool we have to take them to the next level, but they will also have to step up." - Darren Cox
Nissan is aiming to put an American behind the wheel of one of its LMP1 racecars in 2016 as part of plans to grow its motorsports program in the United States.

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.
