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.

Jaguar Land Rover seeks to block U.S. imports of Porsche, Audi, Lamborghini, VW SUVs

You wouldn’t know it was about Jags and Lambos, to judge by its rather dry name: In the Matter of Certain Vehicle Control Systems. But thatÂ’s the complaint Jaguar Land Rover Automotive Plc filed on Thursday to block U.S. imports of Porsche, Lamborghini, Audi and Volkswagen sport utility vehicles it says are using its patented Terrain Response technology without permission. Jaguar Land Rover, a British carmaker owned by IndiaÂ’s Tata Motors Ltd., said in its filing with the U.S. International Trade Commission that the technology helps negotiate a “broad range of surfaces” and is a key feature in JaguarÂ’s F-Pace and Land Rover Discovery vehicles. “JLR seeks to protect itself and its United States operations from companies that have injected infringing products into the U.S. market that incorporate, without any license from JLR, technology developed by JLR and protected by its patent,” JaguarÂ’s lawyer, Matthew Moore, said in the filing. Representatives of Volkswagen didnÂ’t immediately respond to emails seeking comment on the complaint. Jaguar wants to block imports of PorscheÂ’s Cayenne; LamborghiniÂ’s Urus; AudiÂ’s Q8, Q7, Q5, A6 Allroad and e-tron vehicles; and VWÂ’s Tiguan vehicles. It said there are plenty of other luxury midsize SUV and compact crossover vehicles to meet consumer demand if the SUVs are banned from the U.S. Still, the premium Porsche and Audi lines provide much of the profit VW is using to fund its investments in technology for electric vehicles, autonomous vehicles and further innovations. In addition to the four brands, Volkswagen Group owns other upscale nameplates, including Bentley and Bugatti. The International Trade Commission is an independent, quasi-judicial agency that investigates complaints of unfair trade practices, like patent infringement. It canÂ’t award damages but does have the power to block products from entering the U.S. Owners of patents and trade secrets like it because it can work faster than the federal district courts -- the typical investigation is completed in 15 to 18 months. But Jaguar also filed patent lawsuits against the companies in federal courts in Delaware and New Jersey, seeking cash compensation for the use of the technology. Those cases are likely to be put on hold once the trade commission launches its investigation. The case is In the Matter of Certain Vehicle Control Systems, 337-3508, U.S. International Trade Commission (Washington).

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.
