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.

Car Club USA: CleanMPG Northwest Rally

Car Club USA heads to Los Angeles for the CleanMPG Northwest Rally, where a group of like-minded hypermiling enthusiasts led by Wayne Gerdes attempts to drive from Los Angeles, CA, to Bend, OR, on one tank of fuel. For this challenge, Wayne tapped some of the most accomplished hypermilers in the world, including Guinness World Record holder Bob Winger and Mike Sefton, "the most fuel efficient driver in all of Canada." It doesn't take long for the competition to get heated. "They're not aggressive enough, and it's not going to save them anything by being soft right now," says Gerdes as the group attempts to navigate the Interstate traffic. "Driving in Los Angeles is a hyper miler's nightmare," says Winger. The trip will challenge both car and driver, while putting the latest fuel-efficient tech to the test. Wayne is piloting the Volkswagen Golf Sportwagen TDI, Sefton drives the Audi A3 TDI, and Winger attempts the trek in a Honda Accord Hybrid. It's diesel versus hybrid tech on this fuel-efficient trip of a lifetime. Each Car Club USA episode features a different car club or event from across the US, where passionate owner communities gather to share automotive experiences and embark on incredible adventures.

Fully Charged rolls into season 3 with VW XL1 and electric Land Rover

It's been some time since last we visited with British actor and electric car proponent Robert Llewellyn and his web-based video series, Fully Charged. The show, now sponsored by Ecotricity, has started rolling out its third season and now has available two episodes featuring a pair of truly unique – and diametrically opposed – vehicles. The first installment starts with some interesting numbers involving the host's Nissan Leaf and its energy consumption over the past 36,000 miles, but soon moves on to the ultra-aero, ultra-expensive Volkswagen XL1. Now, if you've already seen the footage from our own XL1 first drive review, there's not a lot new here except, perhaps, more enthusiasm and a better listen of the two-cylinder diesel kicking in. Still, it's a great reminder of a truly unique vehicle and we enjoyed the segment. The second episode features an electrified Land Rover Defender 110. This is a vehicle you'd more likely see on an African safari than at the local mall. It's not a home-built conversion either, but rather, something the company has put together "for the boffins to create the ideas and see if they work." Boasting a 50-mile range, it's certainly something we like to take on an off-road adventure. Llewellyn is given the chance to do just that, and though the course is somewhat milder than what we might attempt, it does feature a stretch of river and some rough, rutted tracks.
