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 builds 250,000th Passat in Chattanooga in just two years

It hasn't been without incident or union organizing drive, but the Volkswagen plant in Chattanooga, TN has built its 250,000 Passat in just a little over two years. The Night Blue Passat TDI with black leather has come just two years and five weeks after the first customer car came off the line on April 18, 2011.
In the last year the plant operated at the 150,000-unit capacity that it was intended for, but the downturn in Passat sales and subsequent worker layoffs mean it will be a challenge to repeat the feat. The plant does have the world's largest solar park, though, and you can't take that away from them.

VW and partner SAIC start building $2.5B Audi plant in China

BEIJING — Volkswagen AG's China joint venture with SAIC Motor Corp has started building a $2.5 billion new energy vehicle (NEV) plant in Shanghai, which will make VW's luxury Audi brand cars, a possible first for the venture. The new plant is a key step for Audi to diversify production of its cars in the world's largest car market from its long-standing local partner, China FAW Group Corp. This shift has been delayed amid resistance from local dealers. SAIC Volkswagen said the new plant would have an annual capacity to make 300,000 cars and begin production from 2020. Audi sold 481,387 vehicles in China from January to September this year. The announcement comes the same week Tesla secured a Shanghai location for a Gigafactory battery plant to serve the Chinese market. Audi unveiled the plan to bolster ties with SAIC in late 2016. Earlier this year, the Germany luxury carmaker bought a 1 percent stake in the SAIC Volkswagen venture, paving the way for the joint venture to produce and sell Audi cars. Volkswagen currently gets a larger proportion of the proceeds from the 50-50 tie-up with SAIC than from its 40 percent stake in the venture with FAW. SAIC Volkswagen said in a statement on Friday the plant would cost 17 billion yuan ($2.5 billion) and would make VW and Skoda models as well as Audi cars. It will help VW tap China's fast-growing market for NEVs, a category comprising electric battery cars and plug-in electric hybrid vehicles.
