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.

Toyota reclaims global sales crown, GM and VW not far behind

TheDetroitBureau.com reports Toyota has retaken the global sales crown. The Japanese automaker turned out 9.75 million vehicles last year, putting it just ahead of General Motors, with 9.29 million vehicles. Volkswagen, meanwhile, filled out the podium by building 9.1 million units in 2012.
Still, Toyota numbers fell just below projections the automaker made earlier in the year, due largely to a fierce territorial dispute between Japan and China that has seen mainland buyers shun Japanese goods. But the news marks a substantial comeback for Toyota. The company fell to third place in the global production race in 2011 after tragic earthquake and tsunami caused several plant closures.
In Japan, Toyota enjoyed a sales increase of 35 percent over the previous year, while the company's worldwide sales jumped by 23 percent thanks in part to new additions to the Prius line. The automaker is forecasting yet another increase for 2013, with the company projecting to reach 9.91 million units this year. Neither Volkswagen nor GM have released their own projections just yet.

Volkswagen E-Co-Motion Concept brings electric mobility to the commercial set

Volkswagen sees a future where the bulk of the world's freight is moved into city centers by train, then offloaded onto a fleet of smaller, light-duty commercial vehicles for final delivery. Those vehicles could wind up looking something like the company's E-Co-Motion Concept that debuted at the 2013 Geneva Motor Show. The EV features a modular underfloor drive unit comprised of a battery, motor and gearbox that can be paired with any number of cab and body configurations to suit a buyer's needs, from a refrigerated box to a standard flat bed.
The E-Co-Motion Concept features a rear-mounted electric motor with 113 horsepower and 199 pound-feet of torque. A standard 20 kWh battery pack provides a driving range of up to 62 miles, while 30 kWh and 40 kWh packs could deliver 93 and 124 miles of travel, respectively.
