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.

New investor allows Suzuki to fend off VW

After years of legal wrangling, the long-soured partnership between Volkswagen and Suzuki looks finally to be coming out of arbitration, according to Bloomberg. As a sign of the Japanese brand's improved fortunes, hedge fund Third Point LLC recently bought an undisclosed stake in the company. The investor reported seeing a major opportunity in the successful Maruti Suzuki business in India. As an investment, the only major problem that Third Point found with Suzuki was its legal battle with VW. "The company's greatest asset is its low-cost manufacturing process for vehicles for the emerging market consumer," the fund said in a letter, according to Bloomberg. Third Point reportedly also wants a seat on Suzuki's board, despite being a minority shareholder. The alliance between Suzuki and VW goes back to late 2009. In the deal, the Japanese brand was meant to get access to cutting-edge tech, and the German firm got a helping hand towards better establishing itself in India and Southeast Asia. Things didn't go as planned, though. Less than two years later, Suzuki's boss publicly derided the deal. Eventually, the allegations started going back and forth, and the two have been working out a way to untangle practically ever since. Among the biggest issue has been how to get back the 19.9 percent stake that VW purchased. According to Bloomberg, the arbitration is now technically over. With the divorce nearly final, the two sides are just waiting on a decision on how to split things up. Suzuki may even just buy VW's stake to get the shares back.

Will Audi's e-tron SUV's range match the Tesla Model X?

Tesla may soon get some competition from across the Pond when it comes to battery-electric SUV supremacy. Volkswagen's Audi division is preparing an SUV sized between its Q5 and Q7. And the company is suggesting that the model's single-charge range may challenge that of the Model X. Audi's battery-electric SUV, which was first shown off in a concept version at the Frankfort Auto Show in 2015, may start sales as soon as next year. More importantly, the model could have a single-charge range of more than 300 miles, UK's Autocar says, citing an interview with Audi executive Dietmar Voggenreiter. Granted, that estimate is likely for Europe's more generous NEDC cycle, which would put the range at closer to 250 miles by US Environmental Protection Agency (EPA) standards. Still, 250 miles would beat the 200-mile range of the base-model Tesla Model X and would be in spitting distance of the 100D model's 295 miles. What that means for US customers - price, on-sale date, and range - is unclear. Audi spokesperson Amelia Fine-Morrison, in an e-mail to Autoblog, said it was "too soon to confirm the details," and that the automaker would disclose more information closer to the official launch date. Still, Audi has said it looks to have as much of 25 percent of its global offerings be electrified by 2025, so this will likely be a big step towards that goal. Then there's the question of how big the domestic market will be (not to mention how much the Audi SUV EV will cost). During the three months ended Dec. 31, 2016, Tesla delivered a quarterly-record 9,500 Model X vehicles, so there will obviously be high-end demand for an electric SUV from an established brand like Audi.
