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: AutoNation CEO calls anti-Tesla laws unnecessary, Common Pence donates subway money

Volkswagen has presented a list of near-term technologies to improve fuel economy and decrease emissions. The list includes an addition to a coasting function in its stop-start system, a 10-speed DSG transmission and a more power-dense four-cylinder TDI engine. Volkswagen aims to be the world's most sustainable automaker by 2018 through electric mobility, improved design and increased environmental performance from internal combustion vehicles. Volkswagen also announced other technologies for increased interactivity and connectivity in its vehicles. Read more at Green Car Congress. Commence Pence is a system that allows subway riders in London to donate their unused transit money to charity. People visiting the city often load up enough on their subway card (called Oyster Card) to get them through their trip and end up with unused funds leftover. Zander Whitehurst, a British designer, has created a device that can use the card's RFID to accept leftover funds, which then get diverted to charity rather than reverting back to the agency in charge of running the subway fare system. See the video below or read more at Wired. Mike Jackson, CEO of AutoNation has called Michigan's efforts to ban Tesla's direct sales in the state "unnecessary protectionism." The statement comes as a bit of a surprise, as it dissents from the majority of auto dealers who support a franchise model, as well as laws that forbid automakers selling directly to the consumer. "If Elon Musk wants to make a mistake and go with an inefficient distribution system, that's his right as an American," says Jackson, showing he feels he has little to fear from the electric automaker. Jackson has more to say on the matter, which you can read over at Green Car Reports. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

VW ID.4, the new Buick Envision and crossing Hyundai's N Line | Autoblog Podcast #668

In this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd. It's a review-packed episode this week, but it kicks off with a discussion of Volvo's plans to electrify by 2030 and move their EV sales online. From there, they get into Greg's time with VW's game-changing new ID.4 electric crossover. Byron then talks about his time with two very different new vehicles: the 2021 Buick Envision luxury crossover and the 2021 Hyundai Sonata N Line, which may or may not be a sport sedan. Finally, they tackle a fascinatingly complex twitter question: What is the best 'economy' muscle car?
