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.

Audi CVT suit settlement given green light, 64,000 cars covered

Audi drivers, listen up. If you bought or leased a 2002-06 model-year A4 or A6 with a factory-installed Continuously Variable Transmission (CVT) that failed, you may be entitled to reimbursement under a recently settled class-action lawsuit with corporate parent Volkswagen.
According to Automotive News, the settlement covers about 64,000 vehicles and alleges that "manufacturing and design problems caused the transmissions to fail and left owners stuck with repair costs." While the suit also argues Audi was aware of these issues (going so far as to hide that knowledge from consumers), the settlement stops short of acknowledging any wrongdoing by the German automaker.
Audi drivers are eligible for a cash reimbursement if their CVT repairs occurred within 10 years or 100,000 miles of the date they bought or leased the vehicle before June 19, 2013. To be eligible for compensation, drivers must submit a claim form (found here) with supporting documents by November 18.

Recharge Wrap-up: Volkswagen adopts CCS Combo plug, Tesla adds Trip Energy Prediction

Volkswagen plans to use CCS Combo plugs as standard for all future plug-in vehicles. The CCS fast-charging allows cars to charge to 80-percent capacity in as little as 15 minutes for cars like the Cross Coupe GTE. This could be a boon to prospective customers, as studies have found plug-in hybrid drivers plug in more frequently than originally expected. Plug-in drivers seem to want to perform as much driving as possible using electricity alone, and VW's plan to adopt the CCS Combo plug could help drivers achieve that. Read more at Green Car Reports. Tesla's 6.1 Firmware update for the Model S includes a Trip Energy Prediction feature. The new feature takes into account things like elevation, speed and predicted driving behavior to estimate the amount of energy used and how much range will be left in the battery after a route is programmed into the navigation system. It can let the driver know if a round trip can be made, and if the driver will need to charge before heading out. The feature updates itself in realtime throughout the drive as well, responding to how much energy is actually being used. Read a rundown of Trip Energy Prediction at Teslarati. The dates for National Drive Electric Week have been set for Saturday, September 12 through Sunday, September 20, 2015. The grassroots celebration of EVs is organized by Plug In America, The Electric Auto Association and the Sierra Club. "We're revved up for National Drive Electric Week 2015, which will offer the public, the media, and policymakers a great opportunity to come check out many of the 20-plus plug-in vehicles on the market," says Sierra Club EV Initiative Director Gina Coplon-Newfield. Last year, more than 90,000 people participated in 152 cities worldwide. Read more in the press release below. National Drive Electric Week 2015-DATES ARE SET SAN FRANCISCO, Calif., Jan., 20, 2015-Dates have been set for the fifth annual National Drive Electric Week: Sat., Sept. 12 through Sun., Sept. 20, 2015. Events will encompass two weekends to give planners maximum flexibility and consumers plenty of opportunity to attend. "This promises to be an exciting year for plug-in vehicles," said Tom Saxton, Plug In America's chief science officer. "The BMW i3 will be on the road for the first full year, we expect deliveries of the Tesla Model X, an updated Chevy Volt, and greater overall sales growth than we saw last year.
