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.

Translogic 168: CES 2015 Roundup

Translogic and the yearly CES glorious gadget geekout go together like digital peanut butter and high-def jelly. At this year's show, surrounded by an egg-shaped Mercedes-Benz concept and the re-introduction of, of all things, the Sony Walkman, we had some fun. Between talking with Volkswagen about its new gesture-control tech and flying some video drones, we squeezed in some time to shred on ZBoard's new electric skateboard. The future is now.

VW Super Bowl teaser with Jimmy Cliff is like a less-mean Tosh.0 Web Redemption

Reggae super-duper-star and Rock and Roll Hall of Famer Jimmy Cliff has been using music to send positive vibes out into the universe for decades now, so its no surprise that his message on behalf of Volkswagen is one of redemption.
Dubbed Sunny Side, this web-spot is VW's warmup of sorts for what promises to be another blockbuster year in the world of Super Bowl commercials. Without giving away the game, the euphonious commercial sees Cliff opening his arms and his heart to some YouTube 'celebrities' that might see courser treatment from the likes of Tosh.0, for instance. We can't help but be reminded of Coca-Cola's legendary 1971 Hilltop spot with the "I'd like to buy the world a Coke" lyric, too.
Enjoy the pre-Super Bowl VW spot below, and don't forget to pay it forward... your karma will thank you. For those of you that just can't get enough of commercial-making magic, we've included a "making-of" video, as well.
