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.

Porsche CEO Oliver Blume will be installed as head of the VW brand

Volkswagen Chief Executive Herbert Diess is planning to promote Porsche CEO Oliver Blume to take over as the head of the VW brand, according to a report from Auto Motor und Sport. Citing company sources, the German site said Bernhard Maier, who currently sits at the head of VW's Skoda brand, will lead Porsche in Blume's place. A shuffle at VW isn't surprising. The last thing Volkswagen needs as it transitions away from its long-running "clean diesel" TDI fiasco and into a clean electric ID future is negative press surrounding its burgeoning electrified lineup. Unfortunately, the ID.3 launch has been marred by software issues, with Manager magazine citing company engineers saying "the basic architecture was developed too hastily." Because of that underlying issue, various modules "often do not understand each other" and suffer dropouts. The brand-new eighth-generation Golf launch was also troubled and pushed back due to software problems. And more recently, Volkswagen was forced to pull an advertisement after admitting it was racist and insulting. That marketing misstep, according to the report, will lead to the firing of Chief Marketing Officer Jochen Sengpiehl. Related Video:

Anti-UAW VW workers move to form own union

The struggle over unionization at the Volkswagen factory in Chattanooga, TN, continues to get more complicated. There's now a second union fighting to organize at the plant; although this one is staunchly against the actions of the United Auto Workers. At the same time, the UAW is still signing up voluntary members to its recently created Local 42 at the facility and is reportedly near having a majority of the hourly employees on its side.
The new, anti-UAW union campaign is being spearheaded by employee Mike Burton, according to Reuters, and he calls his group the American Council of Employees. He claims to already have 108 signatures in support of his organization. Burton believes that the UAW is harmful to businesses, and his goal is to force another vote to determine a preferred union among workers.
The UAW was initially defeated (712 to 626) when it attempted a union vote at the Tennessee plant in February. However, UAW secretary-treasurer Gary Casteel told Reuters that Local 42 has already signed up over 700 members. If it can reach a majority of the roughly 1,500 employees, the group hopes VW might consider recognizing it as the factory's union.
