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.

UAW calls on US State Department to help with Nissan plant

The United Auto Workers is calling for reinforcements in its ongoing battle with Nissan at the manufacturer's Canton, MS factory, where the Altima, Armada, Titan and NV (and eventually, the next Murano) are built. The union has been attempting to organize the employees at the factory for several years, but it's been largely unsuccessful.
Now, Reuters is reporting that the UAW is teaming with the IndustriALL Global Union and requesting intervention by the US State Department, with both groups accusing Nissan of using "threats, intimidation and fear" to keep the 5,600 workers at the facility from organizing. The two unions say this violates the guidelines of the Organization for Economic Cooperation and Development, an international organization dedicated to stimulating economic growth.
The UAW and IndustriALL are asking the State Department's National Contact Point to serve as mediator with Nissan, to make sure things play out fairly. Speaking to Reuters, though, there's at least one Michigan-based labor adviser that's skeptical of the move.

Nissan's 'No Charge to Charge' is what incentives look like in the EV age [UPDATE]

Nissan knows that offering free charging can increase Leaf sales, so it only makes sense for them to expand the "No Charge to Charge" program. And that's exactly what happened yesterday. As previewed during the New York Auto Show, No Charge To Charge gives new Leaf buyers free charging at participating public charging stations – which is pretty much any public station – for two years. That's the kind of thing that simplifies the EV buying process, which can move units, Brendan Jones, director of Nissan EV sales and infrastructure, told AutoblogGreen. "There is an expectation that we'll get a sales increase out of this," Jones said. "All the dealer has to say is that we have one card that accesses all chargers and we have a promotion where you can get free charging. The more complexity we reduce, the more sales we get." "The more complexity we reduce, the more sales we get." – Nissan's Brendan Jones That all-access angle is important for the broader EV market, Jones said, calling the program, "The first valid step towards interoperability." Jones said there will be more surprise announcements soon. "The infrastructure companies really came together to support Nissan on this," he said, but added that, "What's good for the industry and EVs in general is good for Nissan." "Leaf customers are not shy about their ability to provide constructive criticism," Jones said, " and interoperability has always been a big concern." Now that many of the early adopters drive an EV, the next target audience are the people who are telling EV companies to "Make this easy for me and I will adopt," Jones said. "[Interoperability] is a necessity for the industry now. We know the experience is great once they drive it. This just takes away a barrier, that confusion at the dealership." And, in some areas in the US, No Charge To Charge is now live. There are 2,600 public stations (200 of them fast chargers) in the initial 10 markets, Nissan says. Those include: San Francisco, Sacramento, San Diego, Seattle, Portland (OR), Nashville, Phoenix, Dallas-Fort Worth, Houston and Washington, DC. Nissan hasn't announced where the next 15 markets will be, but we know that they will likely be wherever the Leaf is selling well and there are a fair number of DC fast chargers. As we reported in April, each charging session in the No Charge To Charge program is limited to 30 minutes if you're plugged into a CHAdeMO fast charge station and to an hour at a Level 2 station.
