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: Smart Fortwo engine fires, Tesla finalist for Extole Advocacy and Customer Experience award

NHTSA has launched a preliminary investigation into complaints of Smart Fortwo engine fires. So far, the agency has received eight complaints about the rear engine compartment catching fire in model year 2008 and 2009 Fortwos and quickly engulfing the car. Six of the fires occurred while driving and were preceded by a check engine light. "The safety of our customers is our primary concern, and we are cooperating with NHTSA in its inquiry," says parent company Mercedes-Benz. "We are not aware of any injuries related to this inquiry."

The funds will be used to fix or buy back some 105,000 affected cars, compensate owners between $3,815 and $4,451 above the buyback price, and pay a $11.2 million civil fine. So far, VW has agreed to spend over $18 billion in North America in connection with its diesel emissions cheating, and is expected to settle on a resolution of its 3.0-liter diesel vehicles in the US soon.

The award recognizes companies that turn customers into brand advocates through referral programs. In Tesla's current program, customers who buy a car using a referral link get $1,000 off the price of their car, while referring owners are awarded prizes including a signed Powerwall 2 and invitations to unveiling events. Referring owners are also entered into a drawing to win a Model S or Model X. "With a disdain for paid advertising, Tesla Motors is leading the trend of reaching new customers through existing ones," says Extole. The other finalists are Hanna Andersson and Ulta Beauty.

Hyundai tops VW and Buick in China, survey says

You may be aware of the long-time competition in China between Volkswagen and Buick, but another brand apparently should be in that conversation too: Hyundai. In a recently published annual consumer survey, the Korean company actually took the top spot to beat out its German and American rivals in second and third, respectively. The results were part of the China Brand Power Index that interviewed 11,500 people around the nation and was paid for by the country's Ministry of Industry and Information Technology. While Hyundai proved popular with voters, its sales haven't necessarily shown that yet. According to Bloomberg, the brand had falling numbers in China for the first quarter of the year. Even Ford outsold the South Korean automaker in the same period, despite scoring lower on the survey. Meanwhile, Audi ranked as the populace's favorite luxury brand, which is hardly a surprise given the Four Rings' strong sales in China. In January alone the automaker saw a 15-percent boost in volume there. Parent company VW's strong performance was somewhat more surprising, though. State media severely criticized the German automaker in March, and customers protested last year for the allegedly poor handling of a recall.
