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.

Auto execs surveyed say VW, BMW most likely to grow

A new survey of top global automotive executives indicates both Volkswagen and BMW are the most likely to grow their market share over the next five years.
Tax advisory firm KPMG LLP has released its 14th annual Global Automotive Executive Survey, which includes responses from over 200 executives. A total of 81 percent of respondents said they expect to see Volkswagen make gains, compared to 70 percent last year. BMW, meanwhile, saw 70 percent of those surveyed say they believe the company will increase its market share. That's a jump of 7 percentage points over last year. This is the first time in the history of the survey that BMW has claimed the second-place spot.
Meanwhile, Hyundai has seen its perceived market share potential slacken for the third year in a row. Around 61 percent of those surveyed predicted gains for Hyundai, down from 63 in 2012. Toyota also has a surprising year, but for just the opposite reason. While the manufacturer had slipped in ranking since 2011, it enjoyed the largest increase of any company in the 2013 survey, jumping to 68 percent from 44 percent last year.
