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 board members facing another ˆ1.8B lawsuit over VW takeover bid

Back in 2008, Porsche got the bright idea that it could take over Volkswagen in the midst of the worst economic slump since the Great Depression. Ignoring that this was a catastrophic move for the Stuttgart sports car manufacturer that that eventually resulted in it nearly going bankrupt and eventually being taken over by the same company it sought to control, the aftermath has left Porsche Chairman Wolfgang Porsche and board member Ferdinand Piëch in the crosshairs of seven hedge funds that lost out during the takeover and are now seeking €1.8 billion - $2.43 billion US - in damages from the two execs, according to the BBC.
See, investors bet on Volkswagen's share price going down, partially because Porsche said it wasn't going to attempt a takeover. But Porsche was attempting to take over VW, having bought up nearly 75-percent of VW's publicly traded shares. When word broke that Porsche owned nearly three-quarters of VW (which indicated an imminent takeover attempt), rather than go down like the hedge funds bet it would, VW's share price skyrocketed to over 1,000 euros per share, according to Reuters.
Naturally, when you bet that a company's share price is going to drop and it in turn (temporarily) becomes the world's most valuable company, you lose a lot of money, unless you're able to buy up shares before prices jump too much. This led to a squeeze on the stock, which the hedge funds accuse Porsche and Piëch (who are both members of the Porsche family and supervisory board) of organizing.

VW pondering low-cost sub-brand for China?

More detail is being sketched into the Volkswagen Group's plan to launch a low-cost brand for emerging markets. Late last year a German report quoted a VW rep saying that the brand has been interested in building a no-frills car, the kind that would challenge Dacia and Datsun, for a while. With both Proton and Suzuki effectively out of the partnership picture, a report in Reuters suggests VW could go straight to China, developing a car with its joint venture partners and building and selling it there.
Officially, company CEO Martin Winterkorn said the issue of a model for emerging markets would be decided this year but VW isn't any closer to confirming any kind of plan for a car in its portfolio underneath the Up!, remarking to Reuters about the China possibility, "That's an issue we're currently looking at."
