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.

NA auto output to reach 11-year peak

According to Automotive News, automakers are expected to manufacture 16 million light vehicles in North America in 2013. That's up 500,000 units from last year and marks the largest number since 2002. The prediction comes courtesy of LMC Automotive and IHS Automotive, which point to the improving US economy as a bellwether for total production. LMC Automotive says North America will produce 16 million vehicles while IHS has a slightly more optimistic forecast of 16.1 million units. A total of seven automakers are slated to increase production on the continent this year. Nissan is set to see the largest jump at 20 percent over last year.
Volkswagen, meanwhile, is one of the only manufacturers predicted to scale back production. Analysts expect the German company's output to fall by 23 percent to 170,000 units, thanks in part to slow demand for the Volkswagen Passat and Jetta.

Volkswagen bringing driver assistance systems to its 2016 lineup

Chevrolet isn't the only manufacturer rolling out luxury safety technologies on a 2016 mass-market lineup. Volkswagen has just announced that next year it will begin adding driver assistance systems to its lineup here in the States – stuff that was previously only available on Audi and Porsche models here, or Volkswagens in Europe. Adaptive cruise control, forward collision warning, and autonomous braking will be standard on the CC V6 4Motion, optional on certain trims of the Golf and Jetta. Blind spot monitoring will be standard on the Beetle, and top CC and Jetta trims, but optional on the Golf and lower Jetta variants. Automated parking will be available on Golf models, including the e-Golf. Blind spot assistance with rear traffic alert, lane departure warning, park distance control, and an automatic post-collision braking system also come in the technology kitty, all of which will be packaged at prices between $695 and $1,495. Infotainment options take a bit step up, too, with every VW model but the Touareg being fitted with touchscreens. The new MIB II head unit comes in four sizes, the Beetle, Jetta, and Tiguan getting the smallest, five-inch screen as standard but upgradeable to a 6.5-inch screen. Android Auto, Apple CarPlay, and MirrorLink are integrated into that larger screen. The interface is improved by a faster processor, higher resolution, and better graphics, and some will come with swiping and pinch-to-zoom functionality. The two press releases below lay it all out in detail. VOLKSWAGEN DEMOCRATIZES HIGH-END DRIVER ASSISTANCE FEATURES FOR THE 2016 MODEL YEAR Many models in the 2016 Volkswagen lineup offer new driver assistance systems that used to be the sole preserve of premium and luxury vehicles Herndon, VA Jul 29, 2015 — For the 2016 model year, Volkswagen is offering a host of driver assistance features that were only previously available on the premium Touareg SUV—and adding some new ones that truly democratize driver assistance for the compact sedan and compact hatchback classes. These available features include: Forward Collision Warning and Autonomous Emergency Braking (Front Assist); Adaptive Cruise Control (ACC); the Parking Steering Assistant (Park Assist); and an active Lane Departure Warning (Lane Assist) system. The Beetle, CC, e-Golf, Golf, Golf GTI, Golf R, Golf SportWagen, and Jetta offer these available features, depending on model and trim line.
