Automakers drop support for Trump effort against California emissions

WASHINGTON — Toyota, Fiat Chrysler (now known as Stellantis following its merger with Peugeot) and other major automakers said on Tuesday they were joining General Motors in abandoning support for former President Donald Trump's effort to bar California from setting its own zero emission vehicle rules. The automakers, which also included Hyundai, Kia, Mitsubishi, Mazda and Subaru, said in a joint statement they were withdrawing from an ongoing legal challenge to California's emission-setting powers, "in a gesture of good faith and to find a constructive path forward" with President Joe Biden. The automakers, along with the National Automobile Dealers Association, said they were aligned "with the Biden administrationÂ’s goals to achieve year-over-year improvements in fuel economy standards." Nissan in December withdrew from the challenge after GM's decision in November shocked the industry and won praise from Biden. On Monday, the Justice Department asked the U.S. Appeals Court for the District of Columbia to put the California emissions litigation on hold to "ensure due respect for the prerogative of the executive branch to reconsider the policy decisions of a prior administration." Biden has directed agencies to quickly reconsider TrumpÂ’s 2019 decision to revoke CaliforniaÂ’s authority to set its own auto tailpipe emissions standards and require rising numbers of zero-emission vehicles, as well as Trump's national fuel economy rollback. Asked to respond to the automakers' action, White House climate adviser Gina McCarthy said in a statement that "after four years of putting us in reverse, it is time to restart and build a sustainable future, grow domestic manufacturing, and deliver clean cars for America." California Governor Gavin Newsom praised the automakers on Twitter for "dropping your climate-denying, air-polluting, Trump-era lawsuit against CA" and urged them to join the voluntary framework. TALKS WITH BIDEN Separately, an industry trade group on Tuesday proposed to start talks with Biden on revised fuel economy standards that would be higher than Trump-era standards but lower than ones set during the prior Democratic administration. The Trump administration in March finalized a rollback of U.S. Corporate Average Fuel Economy standards to require 1.5% annual increases in efficiency through 2026, well below the 5% yearly boosts under the Obama administration rules it discarded.

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.

Renault to Nissan: Stop trying to contact our board members

TOKYO/PARIS — Renault told alliance partner Nissan to stop contacting the French company's directors ahead of a Thursday board meeting as the Japanese automaker tried to share evidence of wrongdoing by its ousted chairman, Carlos Ghosn, two sources said. Ever since Ghosn's Nov. 19 arrest in Japan, Renault and the French government, the automaker's biggest shareholder, have demanded to see the findings of a Nissan internal investigation that include allegations of financial misconduct by the 64-year-old executive. Ghosn was charged on Monday in Japan for failing to declare deferred income he had agreed to receive for the five years ending March 2015. While Nissan fired him as chairman days after his arrest, he remains chairman and CEO of its French partner. Renault's board meets on Dec. 13, and the findings of Nissan's investigation will be shared at the meeting where Ghosn's future could be also debated, one of the sources with knowledge of the matter said. The French firm told Nissan not to contact its directors ahead of the meeting, because such contact was outside the agreed channels for communication of the sensitive findings, the source said. Nissan offered last week to brief Renault's board about findings on what it considers proof of wrongdoing by Ghosn, said a second source who has knowledge of the matter but declined to be identified as it was confidential. But Renault advised Nissan to brief its lawyers instead, which led to a meeting between the Japanese firm's officials and Renault's legal teams early this week in Paris, the person said. The Japanese automaker later invited Thierry Bollore, who was named Renault's deputy CEO with the same powers as Ghosn a day after his arrest, as well as board members, to examine the contents of the findings, said the source. Bollore, though, told Nissan on Tuesday to "refrain from contacting the board," the source said. The exchange between Renault and Nissan is another example of the testy relationship between the two automakers, despite assurances by executives on both sides to preserve the alliance. The alliance, of which Ghosn has been the driving force, is widely seen as vital for the members' long-term survival. Board members invited to see the evidence included Martin Vial, who heads the French state shareholdings agency, interim Chairman Philippe Lagayette and independent director Patrick Thomas, the second source said. A Renault spokesperson declined to comment.
