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.

Mercedes, Nissan and VW slammed by China's CCTV

Several automakers in China, including joint ventures with Nissan, Volkswagen and Mercedes-Benz, are in hot water because their dealers are allegedly overcharging customers for repairs. China Central Television, the country's state broadcaster, leveled the claims during its annual Consumer Day expose. CCTV runs these reports each year on March 15 and often takes aim at foreign companies operating within China. This year the focus fell on automakers, according to the Financial Times, and no domestic car companies were targeted. The network also accused dealers of overselling parts, and it took aim at Jaguar Land Rover specifically for problems surrounding transmission repairs, according to Reuters. The yearly stories are often criticized for focusing on outside businesses. "It panders to a certain type of nationalism as it tends to target foreign companies and rarely touches large state groups or monopolies," Qiao Mu, a journalism professor at Beijing Foreign Studies University, said to the Financial Times. Foreign automakers seem to face tighter scrutiny when doing business in China than their domestic counterparts, in general. The government there investigated several luxury brands, including Audi and BMW, last year for how they supplied spare parts and whether the components were overpriced. Some incurred fines, and Lexus decided to lower its prices. Volkswagen also experienced protests when owners felt the company wasn't handling a recall properly. The CCTV report also comes as many auto dealers in China are feeling a pinch due to high mandated sales targets from automakers. The situation was so dire in early 2015 several brands cut back sales targets and in some cases even paid the sellers to offset poor profits.

Vahland leaving VW over dispute on how to run NA region

On November 1, Winfried Vahland was supposed to take over Volkswagen Group's recently created North American region that combines Canada, the US, and Mexico. But the longtime exec has instead decided to leave the automaker after a dispute over how to manage the new combined region. Vahland is currently the boss at Skoda, and in a statement about his departure the Czech company said: "Differing views on the organization of the new Group region have led to this decision; this decision is expressly not related to current events on the issue of diesel engines." Vahland is leaving at his own request, the announcement says. Vahland was appointed to run to North American region during VW's massive corporate shakeup on September 25. The decision was part of the automaker's plan to put a greater emphasis on regions and brands, rather than on centralized authority. According to Automotive News Europe citing a report from Germany's Auto Bild, Vahland was passed over for the CEO job, with Matthias Muller taking that position. Amidst the changes, Michael Horn remained at the helm of Volkswagen Group of America, reporting to the new regional boss. Vahland joined the automaker in 1990 and started running VW's operations in China in 2005. He became boss at Skoda in 2010. "In the last 25 years, Prof. Vahland made a great contribution to the company. We respect his decision and thank him for his exceptional performance," Muller said in the departure announcement. Prof. Dr. Winfried Vahland leaves Volkswagen Group 14.10.2015 Prof. Dr. Winfried Vahland leaves Volkswagen Group Mlada Boleslav, 14 October 2015 – After 25 years of successful work in Volkswagen Group, most recently as Chairman of SKODA, Prof. Dr. Winfried Vahland is leaving the company at his own request. Prof. Vahland will therefore not be taking up the position of overall responsibility for the North American Region (NAR). Differing views on the organisation of the new Group region have led to this decision; this decision is expressly not related to current events on the issue of diesel engines. Prof. Vahland began his work in Volkswagen Group in 1990. After holding several key positions at home and abroad, he took over Group responsibility as President and CEO of Volkswagen in China in 2005 and contributed significantly to the successful new direction of Volkswagen in China. He was appointed Chairman of the Board of Management of SKODA in 2010.
