VW decides against active-cooling system for e-Golf lithium battery

When the 2015 VW e-Golf was introduced at the LA Auto Show last year, VW said it would come with a water-cooled battery. During the Detroit Auto Show, when the car was trotted out again, VW released a new press release that stripped out the "water-cooled" language, but this change went unnoticed. During a recent VW event in Germany, a friend from Green Car Reports realized that the battery on display did not seem to have any water-cooling mechanisms. That set us off on a bit of a sleuthing and we have now learned that VW is not going to include any active cooling in the upcoming e-Golf. In fact, the company is entirely confident that this car - because of what it's designed to do - doesn't need it. "The need for a cooling system wasn't there" - VW's Darryll Harrison VW has been working on an electrified Golf for ages now, and so changes to the plan are to be expected. But battery cooling is vitally important not just to keep the car operating properly but because when things get too hot, there can be serious public relations problems. Nissan began testing a new battery chemistry for the Leaf in 2013 after an uproar from warm-weather EV drivers in Arizona who were experiencing worse-than-expected battery performance. The Leaf has always used an air-cooled battery, which is another way to say that there is no active cooling system (more details here). Tesla CEO Elon Musk once said this approach is "primitive." So, why is VW following the same path? We asked Darryll Harrison, VW US's manager of brand public relations west, for more information, and he told AutoblogGreen that VW engineers discovered through a lot of testing of the Golf Mk6 EV prototypes, that battery performance was not impacted by temperatures when using the right battery chemistry. That chemistry, it turns out, is lithium nickel manganese cobalt oxide (NMC) in cells from Panasonic. These cells had "the lowest self-warming tendency and the lowest memory effect of all cells tested," Harrison said. He added that VW engineers tested the NMC cells in places like Death Valley and Arizona and found they didn't warm very quickly either through operation, charging (including during fast charging) or through high ambient temps. "The need for a cooling system wasn't there," Harrison said.

Former chairman Piech opposing his nieces' VW board nominations

Someone needs to option the rights to the Ferdinand Piech story for an HBO series, because it perfectly mixes the corporate intrigue of Mad Men with the family drama of The Sopranos. Plus there are some cool cars. In the latest episode, Piech isn't happy with Volkswagen's appointment of two of his nieces – Julia Kuhn-Piech and Dr. Louise Kiesling – to replace he and his wife on the automaker's supervisory board. The recently ousted chairman could try to stop them. According to German publication Bild, Piech thinks his two relatives lack the necessary automotive experience to serve on the board. Therefore, he suggests one-time Ford Premier Automotive Group boss Wolfgang Reitzle and former Siemens manager Brigitte Ederer to take the seats. However, a VW spokesperson told Automotive News Europe that there were no objections to the women's appointment, except for this story from Germany. Piech's nieces are already officially appointed to the VW supervisory board, and it's approved by the Braunschweig Local Court in Germany. His only real option to challenge them would be to file a lawsuit, according to Automotive News Europe. While the new appointees don't have their uncle's decades of history in the auto industry, they do have business experience. Dr. Kiesling has a degree in vehicle design from the Royal College of Art in London and is the managing director of an Austrian textile maker. Kuhn-Piech works in real estate sits on the supervisory board of German truck maker Man.

German judge 'inclined to dismiss' hedge fund lawsuit against Porsche

Last year, around two dozen investors, including hedge funds, leveled a 1.4 billion euro ($1.95 billion at the time) lawsuit against Porsche in connection with the automaker's attempted takeover of Volkswagen in 2008. The Stuttgart Regional Court dismissed the case. Around 19 of those plaintiffs are heading back to court to appeal the ruling and still hope to get 1.2 billion euros ($1.4 billion). However, according to one German judge, the chances for success aren't any better this time around. "On balance it's our view that we consider the lawsuit, or the appeal, to be unpromising for several reasons," Gerhard Ruf, a judge in Stuttgart, said to Reuters. "We are inclined to dismiss the case." The court's ruling on the appeal will be announced on March 26. The investors' case hinges on Porsche's strategy surrounding the botched takeover. The sports car maker said that it wasn't trying to control VW, when in fact it was. These hedge funds had bet against Volkswagen stock, but the share price surged when Porsche's plan inevitably came to light. Investors have sued the sports car company multiple times since then in attempts to recoup billions of dollars. However, none of the lawsuits have been successful, whether attempted in the US or Germany. Former Porsche CEO Wendelin Wiedeking and and CFO Holger Haerter might still stand trial for the alleged stock manipulation, though.
