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.

Regulators consider adding more carmakers to Takata recall

Volkswagen's diesel emissions scandal has been getting a lot of press recently, but the Takata airbag inflator affair could be grabbing headlines again soon. According to Bloomberg, the National Highway Traffic Safety Administration is contemplating an expansion to the campaign that could add seven automakers to the 12 already affected. They are Jaguar Land Rover, Mercedes-Benz, Spartan Motors, Suzuki, Tesla, Volvo Trucks, and VW Group. To be clear, there's no recall for any of these automakers, yet. The government is simply asking for a full list of vehicles that each of them have with Takata-supplied inflators containing ammonium nitrate propellant. The agency is concerned this substance could play a roll in the ruptures. "NHTSA is considering not only whether to issue an administrative order that would coordinate the remedy programs associated with the current Takata recalls, but also whether such an order should include expansion of the current recalls," the letters say. All seven can be viewed, here. From a report supplied by Takata, the government already knows that the company supplied 887,055 inflators with ammonium-nitrate propellant to VW and 184,926 of them to Tesla. In an incident during the summer, a side airbag allegedly burst in a 2015 VW Tiguan. In early September, NHTSA put out a revised report that there were 23.4 million inflators to be replaced in 19.2 million vehicles in the US. An earlier accounting from the agency had about 34 million of the parts in 30 million cars. High humidity is still believed to be among the biggest risk factors for the ruptures. Although, if ammonium nitrate also gets the blame, some already recalled models might need to be repaired again. Related Video:

VW previews huge screens, gesture control with Golf R Touch Concept at CES

Volkswagen is showing off the future of infotainment and connected driving at CES 2015 with a fleet of concepts that highlight its latest technology. According to its displays, the coming years might mean gesture-based vehicle controls and electric cars that drive themselves to find their own charging locations. VW's biggest debut at CES is its next-gen infotainment system, dubbed MIB II. The setup supports a wide array of smartphone integration standards, including MirrorLink, Apple CarPlay and Google Android Auto, to make sure that practically every smartphone user can pair the device's interface with the vehicle. Beyond just keeping occupants entertained, MIB II offers a system called Regular Routes that detects traffic along the driver's regular commute to work and suggests alternatives. The Parking Guide also helps find parking spots that are likely open. If MIB II represents the near future of VW infotainment, then the technology on the Golf R Touch Concept is the next step from there. It takes the brand's hot hatch and adds support for gesture controls inside, plus a trio of massive infotainment screens. This R features a 12.8-inch central infotainment screen, an 8-inch screen below it for things like the climate control and switching media and a customizable 12.3-inch display that digitizes the instrument panel. A camera in front of the central display waits for the driver's hands to make specific movements that activate various vehicle functions. Despite all of the potentially distracting screens, VW says the system offers control without requiring a look away from the road. VW hopes the technology reduces driver distraction and creates a closer relationship with the car. Another of the German automaker's big tech showcases is an e-Golf that demonstrates the potential future of both electric and semi-autonomous driving. This version can be charged inductively, rather than through a traditional power cord, and the exterior lights show when the vehicle is fully recharged. It's also equipped with the e-Station Guide that helps drivers find a charging location and tells them about the payment options there. This e-Golf's other major innovation is VW's Trained Parking system. A camera at the front scans the route to a parking space, and if the driver returns later, then the process can be done semi-automatically.
