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.

Recharge Wrap-up: meet the '66 ZelectricBug, DOE announces home-scale H2 refueling competition

The US Department of Energy has launched the $1 million H2 Refuel H-Prize competition to create small- to medium-scale hydrogen refueling systems. The systems could be home-scale systems that produce hydrogen using utilities at home for refueling, or medium-scale systems to supply locations such as retail centers, apartment complexes or small fleets. The DOE sees hydrogen fueling infrastructure as the biggest obstacle to fuel-cell vehicle adoption and putting the production and refueling in the hands of the consumer could be a way around that obstacle. Read more at Energy.gov and at Green Car Congress. Hyundai has announced a new six-speed automatic transmission with integrated electric motor for new hybrid models. The new configuration puts most of the hybrid powertrain components within the transmission, and the torque converter has been eliminated. The new engine clutch reduces drag with fewer clutch discs, and the mechanical oil pump has been replaced with an electric one. The result is fewer energy losses, improved efficiency and greater mileage. Read more at Hybrid Cars in Reuters or in the press release from Hyundai below. Zelectric Motors has completed its electric 1966 Volkswagen Beetle rebuild, and has put it up for sale. The '66 ZelectricBug, as it's called, is powered by a 50-kW electric motor and 20-kWh battery pack, and offers 120 pound-feet of torque. It has a range of 80 miles, and is capable of at least 100 mph. The stock transmission has been rebuilt. It also has some new goodies like high-performance sway bars, custom shocks, and LED lighting. The '66 ZelectricBug is priced at $45,000. Check it out in the video below and read more at Hybrid Cars. A startup called Alevo says it will build a billion-dollar factory in North Carolina to make longer-lasting lithium iron phosphate batteries. Alevo has purchased an old cigarette factory in Concord for $68.5 million, but it's unclear whether or not the company has secured the $1 billion investment to begin producing batteries. The company plans to create 2,500 to 6,000 jobs and produce several gigawatts worth of batteries per year, which is a tall order for a relatively unknown company. Read more at Gigaom, or in Alevo's press release below. Tesla owners in Shanghai will be exempt from the city's $12,000 registration fee. About 400 people have already received the free license plates in Shanghai, where the government wants to encourage alternative fuel vehicles.
