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.

TN politicians may push to end VW incentives if plant goes union

Volkswagen's Chattanooga Assembly Plant is scheduled to vote on whether to unionize in the coming days, but Tennessee state lawmakers are threatening to deny future tax subsidies to the factory, if the vote is successful. The factory is currently the only Volkswagen plant worldwide that is not unionized.
The states's Republican lawmakers have been particularly vocal against the union vote. Tennessee state senator Bo Watson said during a press conference that VW would have a "very tough time" with future incentives if the vote were successful, according to Automotive News. Tennessee House Majority Leader Gerald McCormick said the "heavy hand" of the UAW is not welcome there. VW has drawn criticism from both sides because it has allowed both pro- and anti-union groups to speak to workers and hand out leaflets.
Roughly 1,500 factory employees will vote on whether to unionize from February 12-14. If successful, the Chattanooga factory would be the first in the US organized under a German-style works council system where white- and blue-collar workers directly negotiate factory issues with the company's management.

Winterkorn will leave remaining VW posts by end of the month

After stepping down as chief executive of the Volkswagen Group last month, Martin Winterkorn still retains a few key positions within and related to the German automaker. According to the latest reports, he's set to resign from those positions as well in the coming days. Aside from his former position as chairman of VW's executive board, Winterkorn has also served (and continues to serve at present) as chairman of the supervisory boards of Audi, truck manufacturer Scania (which is owned by VW), and the group's Truck & Bus division (of which Scania is part alongside Man). He's also the chief executive of Volkswagen's largest stakeholder Porsche SE, having taken up the position after the Porsche/Piech family enterprise acquired its majority stake in the group that also subsumed the sports car manufacturer. In what could prove a strong indicator of things to come, and according to the report from Reuters, Winterkorn was not present at a recent meeting of Audi's board. In his place, the meeting was presided over by deputy chairman Berthold Huber. The former labor leader also served as interim chairman of the VW board after Ferdinand Piech's departure but before CFO Hans Dieter Potsch was named to the post. The companies in question have yet to make any announcements regarding Winterkorn's remaining positions, or confirm the reports regarding his future. However parties close to the automaker and its owners reportedly expect the resignations from those positions to come as well before the end of the month, if not before the week is out.
