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.

VW consumer site finally gets configurator tool back

The traditional vehicle configurator is back on the Volkswagen US consumer website, and it works very well. The company now lets visitors create a virtual model to their own specs and then search for a match among dealer inventories, as is the norm from most automakers. Last summer, Volkswagen tried to break the mold with its thoroughly redesigned consumer website in the US. It sported a slick design but made the highly controversial change of removing the configurator. Instead, visitors were narrowing their selection from a searchable database of models already at dealers. While the streamlined approach immediately told users if their desired car was available, the system also largely hid the prices for options and packages. The newly tweaked design retains the previous tablet-oriented layout, but after clicking a model, the site immediately offers "Build Yours." From there, visitors select a trim, and then the vehicle pops up with options to choose things like colors and packages. The whole layout is clean, features large buttons and works quickly. At the summary page, there's still the opportunity to search for the user's choice in dealer inventories. This is definitely a major improvement.

Audi buys Ballard fuel cell patents for $80 million

While some auto companies (e.g., Toyota and Hyundai) are giving away some hydrogen fuel cell patents, others are paying a pretty penny to gain access to the H2 tech. Audi announced today that it has purchased a suite of fuel-cell patent from Ballard Power Systems. The deal between Volkswagen Group and the Canadian fuel cell pioneer is worth over $80 million US. Unsurprisingly, the value of Ballard's stock shot up about a dollar (to $2.61 as of this writing) on the announcement. VW and Ballard will also extend their development agreement, originally scheduled to end in 2017, to March 2019, and possibly another two years after that. Thus far, the deal – which revolves around the "design and manufacture of next-generation fuel cell stacks" for VW's H2 demonstration program – and Ballard says it is a leader in "critical areas of fuel cell product design – including the membrane electrode assembly (MEA), plate and stack components – along with certain testing and integration work." At the LA Auto Show last fall, VW showed off a Golf SportWagen and a Passat with a hydrogen hybrid HyMotion powertrain as well as a Audi A7 Sportback H-Tron Quattro. Audi buys fuel-cell patents from Ballard Power Systems Development agreement with Ballard extended until 2019 Audi's Head of Development Prof. Hackenberg: "The entire VW Group will use these patents." Ingolstadt/Burnaby, February 11, 2015 – AUDI AG has acquired a package of patents relating to fuel-cell technology from Ballard Power Systems Inc. In addition, the Volkswagen Group has extended its cooperation with the Canadian clean energy company until 2019. The purchase of these patents will provide new impetus for the development of fuel-cell drive systems at Audi, VW and the Volkswagen Group. As explained by Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at AUDI AG and responsible for the steering of the development departments of all brands in the VW Group: "Audi is acquiring these strategically important patents for the entire group and will make them available to all the brands. In this way, we are securing crucial expertise that will provide new impetus for the further development of this technology." Ballard Power Systems Inc. is based in Burnaby, Canada, and is one of the world's leading companies in the technology of proton exchange membrane fuel cells.
