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: VW CEO mulls battery factory, voters approve $201B in transportation funding

Volkswagen Group CEO Matthias Muller says that it would "make sense" for the automaker to begin producing its own batteries. As the company moves toward electrification, Muller says it would be a smart move to build a battery factory. "If more than a quarter of our cars are to be electronic vehicles in the foreseeable future then we are going to need approximately 3 million batteries a year," he says. Volkswagen has agreed to cut 30,000 jobs in its restructuring, while committing to creating 9,000 jobs in Germany through battery manufacturing and mobility services.

Earlier this month, voters in 22 states approved ballot measures adding up to $201 billion in funding for transportation projects, according to the American Road & Transportation Builders Association. California passed 15 transportation measures, including one in Los Angeles worth $120 billion for roads, bridges, and transit. The state of Washington secured $54 billion for light rail and buses. Atlanta approved about $4 billion for road and transit projects. Illinois and New Jersey passed measures to prevent the diversion of transportation user fee revenue to other industries.

A Delaware federal judge ordered the DOE to give the documents – which concern a presentation by Fisker to the DOE in which it falsely claimed to meet milestones set forth in a government loan – to lawyers in a case in which investors claim Fisker lied to them about financial troubles. While the DOE has given over documents already, they were incomplete and heavily redacted. "I understand that such disclosures may have a negative impact on future DOE analyses," says US District Judge Sue Robinson. "but conclude nonetheless that under the circumstances at bar – the public money at stake, the Congressional hearings, and the fact that Fisker Automotive is now a defunct company – the balance of interests favors plaintiffs."

2015 VW e-Golf gets cheaper Limited Editon, starts at $33,450*

Typically when an automaker announces a new limited edition of one of its models, it comes at a premium. Maybe the extra cost turns out to be worth it due to bundled options, but there's almost always a cost. But not with the new Volkswagen e-Golf Limited Edition. For this model, VW has gone the opposite direction by cutting equipment out of the electric hatchback and charging less for it. Compared to the SEL Premium model, the Limited Edition of the e-Golf drops the alloys in favor of 16-inch steel wheels, halogen headlights in place of LEDs, cloth upholstery instead of leatherette, and drops the heat-pump system. As a result, the e-Golf costs $2,000 less, priced at $33,450 (*before delivery) and available to lease for $229 per month. For that, you still get the electric motor with 199 pound-feet of torque, 24.2 kWh lithium-ion battery and 7.2 kW onboard charger and class-leading energy consumption. VOLKSWAGEN ANNOUNCES A NEW TRIM LINE FOR THE FULLY-ELECTRIC 2015 e-GOLF - e-Golf Limited Edition model goes on sale with a starting price of $33,450 - Drivetrain consists of 24.2 kWh lithium-ion battery and an electric motor with 199 pound-feet of torque; 7.2 kW onboard charger is standard - Standard fast charging capability allows up to 80 percent battery charge in 30 minutes - EPA estimated fuel economy rating of 116 combined MPGe puts e-Golf at top of the 2015 EPA Compact Size Class - A great value, with a host of features that include KESSY® Keyless access with push-button start, navigation system, LED Daytime Running Lights (DRL) with C-shaped light signature, and more Herndon, VA – Volkswagen of America, Inc., today, announced that a lower-priced version of the fully-electric 2015 Volkswagen e-Golf will go on sale at participating dealerships. The 2015 e-Golf Limited Edition is priced nearly $2,000 less than its SEL counterpart at $33,450, without compromising performance, quality, or versatility. The e-Golf Limited Edition is also available at a monthly lease price of $229, plus applicable fees. The e-Golf Limited Edition is built on the same sporty Modular Transverse Matrix (MQB) platform as the rest of the award-winning Golf family. It is powered by a compact electric motor and a 24.2 kWh lithium-ion battery (built in-house at the Volkswagen facility in Braunschweig, Germany), and offers 115 horsepower and class-leading torque of 199 pound feet.
