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 planning Up! hybrid model using XL1 powertrain

Even though we've finally gotten a look at the production version of the 261-mile per gallon Volkswagen XL1, this aero-shaped two-seater was never intended for high-volume sales. Fortunately, it sounds like the same isn't true for the car's diesel plug-in hybrid powertrain, which, according to a report from AutoCar, could make its way under the hood of another Volkswagen model: the Up! minicar (shown above).
A potential Up! Hybrid would likely be able to return some of the same impressive fuel economy numbers as the XL1, but it would be a more realistic car with more passenger space and greater production capacity. The hand-built XL1 will use a 47-horsepower, two-cylinder TDI engine paired to a seven-speed dual-clutch transmission, and the 27-hp electric motor and lithium-ion battery helps deliver an all-electric driving range of 31 miles.
One of the core pillars of the XL1's design is its lightweight construction with a 1752-pound curb weight, which makes the Up! a perfect recipient for using this powertrain since it weighs just 300 pounds more. The report says that the Up! Hybrid is still in the developmental phase, so a production version isn't expected for at least another 18 months.

Volkswagen officially grants access to UAW in Tennessee

An audit at the Volkswagen factory in Chattanooga, TN has revealed that at least 45 percent of the facility's workers support unionization, leading the German company to grant access rights to the United Auto Workers. This is a tremendous step in the UAW's long-running and at times contentious pursuit of the workforce at Chattanooga. With this latest move, "local leadership is ready to move forward with additional conversations with the company," the union said in a statement obtained by The Detroit News. "As a starting point, UAW Local 42 will take advantage of the company's offer to establish bi-weekly meetings with Volkswagen Human Resources and the Volkswagen Chattanooga Executive Committee." The News reports that UAW Secretary-Treasurer Gary Casteel, shown above speaking at the Chattanooga plant last summer, claimed these meetings "will remind Human Resources and the Chattanooga Executive Committee of the mutually agreed-upon commitments that were made by Volkswagen and the UAW last spring in Germany. Among those commitments: Volkswagen will recognize the UAW as the representative of our members. We believe Volkswagen made this commitment in good faith and we believe the company will honor this commitment." It's important to note that despite Casteel's remarks, this is not a collective-bargaining agreement, Harley Shaiken, a labor professor at University of California, Berkeley, told The News. "But it is a step in the direction of recognition, which ultimately could lead to collective bargaining. This is not the end point," Shaiken said. "We don't know what's next. We're in unchartered territory."
