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.

Elon Musk says VW scandal proves limits of fossil fuel cars

Tesla Motors chief Elon Musk didn't appear to mince words when commenting on Volkswagen's diesel-emissions scandal when making comments at the Federal Ministry for Economic Affairs and Energy conference in Berlin this week, according to Bloomberg News. Musk called the news of scandal "obviously bad." He also used the opportunity to note that he thought the German automotive industry may be lacking when it came to getting its powertrains to cut emissions. Pretty tough talk in Berlin. Musk did note that, when it came to clean electricity generation, Germany was ahead of many countries. But he also used the occasion to note that global industries could do a better job addressing "the chemical constituency" of the world's air and oceans. Musk also spoke to the Belgian press about the VW scandal this week. Asked if people might lose their faith in green technology, Musk said that what the scandal shows is that "we've reached the limit of what's possible with diesel and gasoline. And so, the time, I think, has come to move to a new generation of technology." You can see his comments in the video above, starting at 1:12. Musk made these comments as the automotive industry reacts to news that Volkswagen tried to game the system by manipulating its diesel-powered vehicles to meet worldwide emissions regulations. VW has set aside $7.3 billion to address the issue, and has estimated that at least 11 million vehicles may have been programmed to cheat emissions mandates. As a result of the scandal, VW CEO Martin Winterkorn has stepped down and Porsche chief executive officer Matthias Muller has taken over. For those keeping track, VW sold almost 51,000 diesel vehicles in the US through the first eight months of the year. That is about eight percent less than a year earlier but is probably about three times the number of Tesla Model S electric vehicles Musk sold in the US (we say probably because Tesla discloses neither monthly nor country-specific sales). So, while this may not be a case of diesel envy, Musk did have a pretty wide-open shot to tweak VW and its reliance on diesel technology.

Volkswagen e-Co-Motion concept poised for delivery to Geneva

With Nissan getting ready to launch the e-NV200, it appears Volkswagen is looking to go after the same zero-emission commercial vehicle market with the all-electric 2013 e-Co-Motion Concept. Debuting next week at the Geneva Motor Show, the e-Co-Motion Concept might be small in size, but VW says it has cargo and payload capacities that should be perfect for small businesses.
Measuring 179 inches long, 75 inches wide and 77 inches tall, the e-Co-Motion Concept has about the same footprint as the current Golf, and it has a cargo capacity of 162 cubic feet and a maximum payload of more than 1,700 pounds. There isn't too much information on the e-Co-Motion just yet - such as what electric components and platform are used - but the press release posted below states while the concept is shown as a cargo van, future body styles could include a passenger wagon or a refrigerated box van.
