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.

EVs still burning aboard ship carrying luxury cars near Azores

LISBON — Heavy tug boats on Tuesday sprayed water on a burning ship carrying thousands of Porsches and Bentleys adrift off the coast of Portugal's Azores islands, the ship's manager said in a statement. The Felicity Ace, carrying around 4,000 vehicles including Porsches, Audis and Bentleys, some with lithium-ion batteries, caught fire on Wednesday last week. The 22 crew members on board were evacuated the same day. Ship manager Mitsui O.S.K. Lines Ltd (MOL) said in a statement the vessel was still on fire but stable, and that no oil leak had been reported so far. It also said the ship was drifting further from the Azores islands in the Atlantic Ocean. Two large tug boats equipped with firefighting gear arrived from Gibraltar on Monday, and were working with another patrol boat to spray water at the Felicity Ace and cool it down, MOL said. The arrival of two other tug boats with more firefighting equipment is scheduled for Feb. 23 and Feb. 26. "Together with the all relevant parties, MOL is making every effort to contain the damage and resolve the situation as soon as possible," MOL said. Joao Mendes Cabecas, the captain of the nearest port on the Azorean island of Faial, said on Sunday the fire had lost its intensity, probably because there was little left to burn. Cabecas said as the fire subsides and the structure cools down, firefighting teams and technicians might be able to board the vessel to prepare to tow it either to Europe or the Bahamas. "When conditions are safe the salvage team will board the Felicity Ace for an initial assessment," MOL added. Cabecas told Reuters over the weekend the lithium-ion batteries in the electric vehicles were "keeping the fire alive." It was not clear whether the batteries had caused the fire. MOL did not immediately respond to a Reuters request for comment on the cause of the fire. Volkswagen, which owns the car brands, said on Monday it did not have any further information to share.
