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.

These EVs are the worst when it comes to depreciation

The Renault Fluence Z.E. tops the list of the worst depreciating cars according to a ranking compiled by Glass' Information Services, holding just 27.21 percent of its value after a year of ownership and 12,000 miles on the clock. Just as well that you can't buy the sedan anymore in either electric or ICE versions, since it was discontinued last year. This car took a particularly rough hit when Better Place declared bankrutpcy, since the electric Fluence was a specific fit for the aspirations of the battery-swapping company. The Citroen C-Zero hits the list at number four, the Nissan Leaf E at number five, both holding onto just a third of their value after a year. The C-Zero is a rebadged Mitsubishi i-MiEV, and if you bought one stock for the full UK on-the-road price of 26,766 pounds, you'd have a car worth 8,583.86 pounds twelve months later, according to Glass. We're not sure about the wording of the press release, though - it states that those three cars "lost more than three-quarters of their value." Yet the Fluence E Z.E. is the worst offender, and it doesn't dip below 25 percent of its original value. As with those electrics, the rest of the list is made up of aged or barebones ICE models, some of them touted elsewhere for their popularity. You can find the full list and the valuations in the press release below. ELECTRIC CARS AMONG WORST FIRST YEAR DEPRECIATORS Fluence, C-Zero and LEAF all lose more than three-quarters of their value 15/07/15 - Three electric cars are among the worst first year depreciators in a "Bottom 10" released by motor trade valuation market leaders Glass's. The Renault Fluence, Citroen C-Zero and Nissan LEAF E have all lost more than three-quarters of their value after covering 12,000 miles during the last 12 months. Rupert Pontin, head of valuations at Glass, said: "The motor trade and the used car buying public remain interested in electric cars but are still reticent to actually buy them in numbers – and these depreciation figures reflect that fact. "To be fair, these three EVs are among some of the least attractive on the market – the Fluence and C-Zero both have a 'last generation' feel while the LEAF E is on the bottom rung of the LEAF range – but their presence does reflect the fact that the EV sector remains sluggish." Other models in the list include the lowest-powered, entry level versions of some generally popular but aging models such as the Vauxhall Insignia and Renault Megane.

Sebastien Vettel testing Infiniti's production Etherea?

It sounds like Sebastian Vettel has had his hands full recently, juggling his Formula One racing career while moonlighting as the newly appointed director of performance at Infiniti. On that latter note, Autocar is reporting that Vettel has been testing a production version of the Etherea Concept at France's Circuit Paul Ricard.
There is still no word as to when we could see this car go into production or what it will be called (possibly the Q30), but it will likely share a platform with the Mercedes-Benz A-Class as a part of the Daimler/Renault-Nissan collaboration. The article also said that this future entry-level Infiniti would be produced at Nissan's Sunderland, UK plant.
