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.

Volkswagen feuds with thriving stablemate Skoda

BERLIN, Oct 4 (Reuters) - Volkswagen managers and unions are seeking to curb competition from lower-cost stablemate Skoda, move some of its production to Germany and make the Czech brand pay more for shared technology, company sources told Reuters. As VW struggles to cut jobs and spending at German factories and turn the page on dieselgate, Skoda's superior car reviews and profitability have intensified the brands' rivalry within the Volkswagen empire. VW now wants to reduce what it sees as Skoda's unfair advantages - combining German technology with cheaper labor - and reaffirm the top-selling brand's primacy ahead of a wave of new electric car launches, the sources said. The tussle between VW and Skoda is reviving tensions at the heart of the Volkswagen group between profits and jobs, and between central control and autonomy for its 12 vehicle brands. "Instead of devoting our efforts to beating Tesla, we may just be setting up a futile internal conflict," said one manager. Once the butt of jokes, Skoda has blossomed under 26 years of VW group ownership into a successful mid-market carmaker, steadily winning business from rivals - including VW - and surpassing even Audi's operating profit margin last year. At the same time, VW is facing thousands of job cuts as management moves to trim excess capacity at German factories. Its powerful domestic unions see Skoda's success as both a threat and a potential lifeline. VW workers' representatives are now demanding the transfer of some Skoda production to their underused German plants, a source close to the supervisory board told Reuters. The proposal aims to offset declining output of the VW Passat and aging Golf that could otherwise threaten more jobs. They are also making the case that Skoda should pay higher royalties to use VW's main common vehicle platform. The so-called MQB architecture also underpins mid-sized models from the group's Audi and SEAT brands. Responding to the news, Czech Prime Minister Bohuslav Sobotka said he would meet Skoda management and unions to ask for clarification. The government will seek to ensure that VW investment plans are followed through and that "production is not moved outside the country," a statement released by Sobotka's office said. Skoda's main union warned that a production shift could cost as many as 2,000 jobs. VW's works council declined to comment.

Auction for first US VW e-Golf raises $41,400 for Global Green charity

Would having Jay Leno on hand have changed the outcome? That's what executives at Volkswagen might be asking after the German automaker auctioned off the company's first electric car in the US for around $6,000 over MSRP. VW auctioned off the first Volkswagen e-Golf in the US to raise money for the environmental non-profit Global Green USA. Bruce Oberg, an EV enthusiast and previous VW owner, proudly cut a $41,400 check for the car, which has a 116 miles per gallon-equivalent rating and is said to be able to go about 80 miles on a single charge. At your local dealer (depending on where you live), the e-Golf starts at $35,445. Sales start later this month in 11 states: California, Massachusetts, New York, Vermont, Oregon, Maine, Maryland, New Jersey, Connecticut, Rhode Island and Washington, DC. The $6,000 premium for first-dib rights for the e-Golf is nice, but it doesn't compare to what BMW worked out this summer. In August, the first i8 plug-in hybrid in the US was auctioned off at California's Pebble Beach Concours d'Elegance for $825,000 (to an unidentified buyer). That's about six times the car's sticker price, but this special edition came with Louis Vuitton luggage and was presented by noted car buff Leno. VW's press release below.
