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 using other manufacturing locations as leverage in battle with TN [w/video]

We've reached a new step in the ongoing drama at Volkswagen's factory in Chattanooga, TN. The United Auto Workers recently dropped its opposition to the union vote and agreed that it wouldn't hold another ballot for at least a year. Now, the new question becomes where VW is going to build its forthcoming midsize SUV.
Earlier, it had been considered all but certain that the SUV, likely a production version of the CrossBlue concept (pictured above), would be built in Tennessee. However, it seems the Chattanooga factory might have competition to produce it. In emails obtained by The Detroit News, VW's lawyer wrote to the Tennessee economic development department in January saying, "While we understand there are some 'non-deal' issues that are causing a delay in the TN solution, VW has been successful in reaching agreement on terms at the alternative locations."
As previously reported, the state of Tennessee allegedly offered VW about $300 million in incentives to build the vehicle there and create an estimated 1,350 jobs, but it later rescinded the deal. Newly leaked documents from NewsChannel 5 (WTVF-TV) in Nashville allegedly show just how close that offer was to being completed. It appears that VW actually sent the government the first draft of a memorandum of understanding agreeing to the incentives, but the state removed the offer in late January.

Recharge Wrap-up: First VW e-Golf in US up for auction, meet Project Ain't Fuelin'

Volkswagen is auctioning the first e-Golf in the US to raise money for Global Green USA. The auction is live now, and bidding goes until 3:30 pm Eastern on October 29. Global Green USA will use the proceeds to help find solutions to climate change, and the winner will get to enjoy emissions-free driving before the car e-Golf goes on sale in November. If you don't live in or near California, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island, Vermont or Washington DC, you might want to sit this one out, as the car will only be available to pick up at dealers in those initial launch states. Go bid now, or learn more in the press release below. Berlin, Germany will use Solaris electric buses for a complete bus line in 2015. The downtown line will run 3.8 miles between Zoologischer Garten Station and Sudkreuz. The transport operator Berliner Verkehrsbetriebe (BVG) will use four of the Solaris e-buses for the test, each about 39 feet long. The buses use a 200-kilowatt inductive charging system at the ends of the line to recharge in just a few minutes. The government-funded test runs through 2016, but BVG pans to use the electric buses beyond that timeline. Read more at Green Car Congress. The American Petroleum Institute (API) is worried that the Obama administration will use ethanol requirements to influence a Senate race in Iowa. In the midst of a close race against Republican Joni Ernst, Representative Bruce Braley, the Democratic candidate, is urging Obama to reject a cut in the Renewable Fuel Standard. The November election approaches, meanwhile the EPA continues to delay issuing an ethanol requirement for the year, with or without its proposed 16-percent reduction. Rejecting the cut could help get farmers and ethanol producers on the side of Braley. "We are very concerned that the signals we are seeing from the administration is that the political calculations are outweighing sound fuels policy," says API's Bob Greco. Read more at Businessweek. Project Ain't Fuelin' aims to fix up old cars to return them to original fuel economy, and then surpass it. Episode 3 of Valvoline's Under The Hood video series features Daniel Gray of MPGomatic, who is doing just that to a 1999 Honda Civic HX Coupe. He aims to get 50 mpg out of the old Civic by tuning it up, tinkering with the aerodynamics, switching to more efficient tires and other modifications.
