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.

Cost-cutting measures put VW Beetle in jeopardy

Volkswagen is on a mission to cut costs. That means producing more models across its various brands based on the same platforms and powertrains, but the latest word from Germany has it that it will also mean cutting some of the VW brand's less successful models. First on the chopping block, according to German publication Der Spiegel, is the three-door version of the Polo, which will reportedly cede its place to the five-door version exclusively. The elimination of that model alone is said to save VW a good 200 million euros, putting it on its way towards reducing the brand's costs by a targeted five billion euros. The Polo isn't the only one in danger, though. The Eos, as we know, is not due to be replaced, but the future of the Beetle could be in jeopardy as well. The Beetle may be one of VW's most iconic models, but is hardly its most successful in terms of sales. With the 2014 annual report due to be released shortly, the last full-year sales figures had Volkswagen selling 109,517 Beetles in 2013. That may be more than four times the number of Scirocco models it sold, but hardly puts a dent in the 871,413 Jettas, 824,629 Golfs and 725,291 Polos it sold during the same year.

VW Chattanooga plant very close to UAW representation

After months of fighting from both sides, it looks like the Volkswagen factory in Chattanooga, TN, might unionize under the United Auto Workers after all. According to a letter acquired by The Associated Press, VW and the UAW reportedly struck a deal last spring where the union agreed to stop its challenge of the organization vote with the National Labor Relations Board to help clear the way for the CrossBlue to be produced in Tennessee. In exchange, the automaker would recognize the UAW at the plant. Leaders of the Local 42 at the facility reportedly signed the letter.
It seems that such an agreement would clear the way for the factory to unionize after months of dispute. According to The Detroit News, under Tennessee law, workers aren't required to join the organization. Although, that might not be a problem. As of a few months ago, Local 42 already claimed to have signed around 700 of the plant's roughly 1,500 workers.
Controversy has constantly swirled around the possible unionization at the Chattanooga plant. The UAW held its official decision in February and lost 712 to 626. However, there were allegations of intense political pressure to make sure the ballot failed. A later report also found that VW was offered $300 million in incentives well before the vote to make sure things progressed to the "satisfaction of the State of Tennessee," but the deal was later retracted. In July, the UAW opened Local 42 on the campus in hopes of signing up a majority of the workforce by volunteering to be a part of it.
