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.

China sticking to its guns on EVs for the future

Automakers are obviously free to develop whatever next-gen, zero-emissions tech that they want. However, if a company wants to get on the good side of the Chinese government, that strategy better include some plug-in vehicles. The authorities there are lending major support to plug-ins at the moment, and its forcing the auto industry to play along. According to Bloomberg, Toyota, Volkswagen, Hyundai, and BMW are all launching dedicated EV brands with their joint venture partners, and as many as 40 electric models could hit the Chinese market this year alone. However, analysts don't think the vehicles are going to sell well. Instead, the launches are essentially a way for companies to play nice with the government and help get the approval to build factories in the country. Take Toyota as an example. The company is pushing the future of hydrogen hard with promotional films for the Mirai and engineers talking down fast-charging EVs. Still, the Japanese automaker is getting ready to launch two EV brands in China with its joint venture partners, according to Bloomberg. China's push for alternative fuels has been happening for a while, but it really kicked into high gear last year. The government has set a goal to improve fleet-wide economy by 40 percent by the end of the decade in order to spend less importing oil and for the population's health. The plan has shown some success so far with hybrid and EV sales growing early in 2015.

Bentley Bentayga bodies to be built in Bratislava

Volkswagen's plant in Bratislava, Slovakia, has come a long way. After getting its start in 1971 by subcontracting the production of Skoda-branded vehicles, the plant was purchased by VW in 1991, where it was quickly put to further good use as it began producing Volkswagen Passat models for export. More recently, Bratislava has become a bastion for SUVs, assembling the Audi Q7 and Porsche Cayenne, in addition to the VW Touareg. Color us unsurprised, then, to learn that the Bentley Bentayga, which will be built atop the same large SUV platform as its cousins from Audi, Porsche and VW, will also be used for at least part of the production of Bentley's first SUV. Surely, though, one of the hallmarks of the Bentley brand is that its cars are handmade in England. Won't the Bentley-buying populace feel slighted by production in Slovakia? Not to worry. As is the case with the Porsche Cayenne, all that will be produced in Slovakia is the Bentayga's body. According to a report from Automotive News, bodies for the Bentayga will be shipped from Bratislava to Crewe, England, where they will be finished into fully operational vehicles. In order to accommodate the additional work, VW will reportedly invest 500 million euros into the plant in Slovakia and hire hundreds of workers.
