U.S. opens probe into whether VW vehicles infringe Jaguar Land Rover patents

WASHINGTON — The U.S. International Trade Commission (ITC) said on Monday it is opening in investigation into whether Volkswagen AG infringed on patents held by Jaguar Land Rover for a system used for off-road driving. In November, Jaguar Land Rover, a unit of Tata Motors, filed a complaint with the ITC seeking to prevent the import of some VW Porsche, Lamborghini and Audi models with "certain vehicle control systems" that allegedly infringe on it patents held for its Terrain Response system. The models include the Lamborghini Urus, Porsche Cayenne and AudiÂ’s Q8, Q7, Q5, A6 Allroad, and E-Tron vehicles and the VW Tiguan. The ITC said it has made no decision on the merits. VW said in a statement it was examining the action and determining its next steps. "We will of course cooperate with investigating authorities. While we cannot comment on any details of the proceedings, we strongly believe that the claims have no merit and will robustly defend our position," VW said. Many automakers offer a suite of off-road powertrain controls, but JLR claims Volkswagen's tech is more than just similar.  Jaguar Land Rover (JLR) said the vehicles "have used JLRÂ’s patented inventions without payment or permission" notably a patent for an "improved system for driving a vehicle on different driving surfaces, in particular off-road." JLR says its Terrain Response technology uses the patented technology to maximize performance on off-road driving surfaces, including grass, snow, mud, sand and rocks.

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.
