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.

The Volkswagen Group switches official language to English

The Volkswagen Group can't be fairly thought of as entirely German anymore, so the news that the company is switching its official language to English to help attract managers and executives is a rational, if surprising, decision. While many VW Group companies are still staidly German in character and culture, consider the other companies that it controls: Bentley (British), Bugatti (French), Ducati and Lamborghini (Italian), Skoda (Czech), Scania trucks (Swedish), and SEAT (Spanish). Not to mention the large Volkswagen Group of America operation, which constructs cars in Chattanooga, TN. Volkswagen's explicit motivation is to improve management recruitment – making sure the company isn't losing out on candidates for important positions because they can't speak German – and that's inherently sensible in a globalized economy. Particularly considering, like it or lump it, that English is the lingua franca of said global economy. It also should make it inherently easier to communicate between its world-wide subsidiaries and coordinate operations. It's hard to say for sure if this will have any impact on the consumer, although it's easy to see the benefits if, say, VW Group hires some American product planners or engineers and they push for features and designs that more closely suit American needs. After all, the US is a hugely important market for any manufacturer, and so the switch to English almost certainly has something to do with the outsized influence of the US in the global economy. And there doesn't seem to be a downside from a purely rational perspective, although it could mean that the Group's corporate culture becomes less German. Whether that's a good or a bad thing depends on your perspective.

Volkswagen Group CEO Martin Winterkorn told European regulators that more stringent emissions standards too soon will be a major problem for automakers. He says that such moves could prove "fatal" for an auto industry that is still working to develop cleaner vehicles. "Every gram of CO2 that we save in our European fleet costs our group almost 100 million euros," says Winterkorn, "100 million that we have to invest in advance, without knowing when these investments pay off." He says that already creating emissions targets beyond those set for 2020 could harm European automakers competing globally. Read more at Automotive News Europe. When a Detroit Chevrolet dealership lost its Internet connection, it turned to one of its Chevy Volts for a temporary fix. After the regular connection at Buff Whelan Chevrolet went down, it plugged in a Volt showroom model equipped with 4G LTE, and used its connection to resume business. The car can handle up to seven connected devices, so the team used a Malibu to connect the rest of its computers. When a customer asked why the Volt was on, the team explained the whole situation, leading to one impressed customer. Read more at Automotive News.
