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.

Child cobalt miners: Automakers pledge ethical minerals sourcing for EVs

BERLIN - Leading carmakers including Volkswagen and Toyota pledged on Wednesday to uphold ethical and socially responsible standards in their purchases of minerals for an expected boom in electric vehicle production. Demand for minerals such as cobalt, graphite and lithium is forecast to soar in the coming years as governments crack down on vehicle pollution and carmakers step up their investments in electric models. To cover its plans for more than 80 new models by 2025, Volkswagen alone is looking for partners in China, Europe and North America to provide battery cells and related technology worth more than 50 billion euros ($59 billion). Talks with major cobalt producers, including Glencore, at VW's Wolfsburg headquarters last week ended without a deal. More than half of the world's cobalt comes from the Democratic Republic of Congo, a country racked by political instability and legal opacity, and where child labor is used in mines. On Wednesday, a group of 10 leading passenger-car and truck manufacturers announced an initiative to jointly identify and address ethical, environmental, human and labor rights issues in raw materials sourcing. The partnership dubbed "Drive Sustainability" consists of VW, Toyota Motor Europe, Ford, Daimler, BMW, Honda, Jaguar Land Rover, Volvo Cars and truckmakers Scania and Volvo. The alliance "will assess the risks posed by the top raw materials (such as mica, cobalt, rubber and leather) in the automotive sector," said Stefan Crets of the CSR Europe business network. "This will allow Drive Sustainability to identify the most impactful activities to pursue" to address issues within the supply chain.Reporting by Andreas Cremer.Related Video: Image Credit: Michael Robinson Chavez/The Washington Post via Getty Images Green BMW Ford Honda Jaguar Land Rover Mercedes-Benz Automakers Toyota Volkswagen Volvo Green Automakers Green Culture Electric Scania ethics mining

Recharge Wrap-up: Jaguar Land Rover talks EVs, Batteries should be modular

A new study out of Germany suggests adopting a modular approach to battery offerings in plug-in hybrid and extended range electric vehicles. Automakers could offer the same car with different battery sizes (and different costs, accordingly) to drivers depending on their driving ranges. This would optimize the total cost of ownership for various drivers better than the current approach. Developing a modular battery design and offering appropriate batteries for different customers "is the key for electric powertrains to meet customer expectations and become cost competitive against conventional technologies," according to the report from the Institute of Vehicle Concepts, German Aerospace Center. Learn more at Green Car Congress. Jaguar and Land Rover are looking to offer more electric driving from their vehicles. Wolfgang Ziebart, head of product development for Jaguar Land Rover, said in an interview that its hybrid system is being tweaked for more electric power and "downsized" combustion. He also said the likely target market for EVs would be second and third vehicles, rather than primary vehicles for urban driving. Within that market, Europeans look for something smaller, while American drivers lean toward larger luxury vehicles for their second car. Ziebart uses the Tesla Model S as an example of American tastes, and compares its size to that of the Jaguar XJ. Read more at Automotive News Europe. Thailand will likely approve a Volkswagen factory as early as next week. A German newspaper suggests that Thailand's Board of Investment is set to greenlight the plant, which is planned for a site near the Port of Bangkok. Thailand is a relatively large and growing auto manufacturing country, which seeks to be a major producer of eco-friendly vehicles. The country's "Eco2" program would provide incentives to Volkswagen if it builds clean cars and meets certain production targets. Read more at Reuters. Formula E has chosen Sky Deutschland for broadcasting rights in the German market. The deal includes television rights, as well as online broadcasting. Sky Deutschland has 3.8 million subscribers in Germany and Austria. Showing the races on Germany's largest pay television provider should help generate interest for the series, particularly the Berlin ePrix - the inaugural season's penultimate race - scheduled for May 30, 2015.
