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.

VW's Winterkorn tells 20,000 staffers of big cost-cutting plans

During a gathering of 20,000 Volkswagen Group employees at company headquarters in Wolfsburg, Germany on Wednesday, CEO Martin Winterkorn dropped a bombshell. The boss stated that the automaker isn't operating efficiently enough and admitted the company needs to radically start cutting back to raise its profit margins. To right the ship, Winterkorn has proposed killing off less profitable models and spending less on research and development.
According to Reuters, Winterkorn wants to raise the VW brand's profit margin from about 2.9 percent in 2013 to a target of 6 percent. To make that possible, his plan amounts to increasing cost cutting until Volkswagen reaches about 5 billion euros ($6.7 billion) per year to get things back in order. "Over the short-term, we urgently need more efficiency and higher profit," the CEO said during his speech, according to Reuters.
However, Winterkorn can't make these decisions unilaterally. Volkswagen's works council also has a seat on the supervisory board to represent laborers, and it isn't likely to take the proposed cuts sitting down.

Touring the Volkswagen Museum in Wolfsburg

Forgive the ribbon up top - this isn't so much of a Read This as a Look At This. Ran When Parked took a tour of the sprawling Volkswagen Museum in Wolfsburg, and while there's a spot of text about the different and unique vehicles on display in the rotating exhibits, it's largely the collection of pictures of odd, one-off VW-badged cars and vans that excites. If you're a fan of the weird and wild, this is a post you'll want to look at.
As RWP points out, this is the larger, but less busy, museum targeted purely at Volkswagen products. The smaller AutoStadt museum, meanwhile, covers a much broader swath, with products from other Volkswagen Group members.
