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.

Toyota holds onto crown of World's Largest Automaker

Although there were hints and allegations that the Volkswagen Group might have taken the global sales crown for 2014, the final tally puts Toyota at the top with 10.23 million sales in 2014. We should really say it keeps Toyota at the top, since that makes three years in a row the Japanese company has been No. 1. Volkswagen Group came in second with 10.14 million units sold, General Motors in third with 9.92 million units sold. This the first time for both Toyota and Volkswagen to pass 10 million sales in a single year. Toyota, including its Hino and Daihatsu divisions, did it with a three-percent increase in company-wide sales on the back of strong demand in Japan and the US. Its strength in developed markets might be the reason it loses the title this year, though; Toyota forecasts a two-percent gain in sales outside of Japan, but a nine-percent drop in its home market because of a new consumption tax that encouraged buyers to purchase before the end of last year. On top of that, turmoil in Southeast Asian economies like Thailand and Indonesia depressed sales in 2014 and they're facing more headwinds. The company envisions 10.15 million sales in 2015. Volkswagen, on the other hand, "has a jet engine strapped to its back called 'China,'" where Toyota is out-of-sorts. Volkswagen Group sales fell 2.9 percent in the US last year, while Toyota gained 6.2 percent here. But Volkswagen roped in 3.7 million sales in China, a 12-percent increase. Toyota enjoyed a huge bump of 12.5 percent in China, but that only got it to 1.03 million units, missing its yearly target and leading to trouble with its Chinese dealers over unsold inventory. With Toyota on the Chinese sidelines while Volkswagen guns for No. 1 status and pledges more production capacity in China – sales there are expected to top 25 million units this year – it looks like this could be the year the VW Group takes over the lead. That would be three years ahead of its original target of 2018. An analyst in Japan said Toyota is more focused on "keeping profitability than chasing numbers" – profitability is an issue for VW right now – so Toyota might not be back at the top "for [the] coming years."

VW bringing fuel cell concept to LA Auto Show

Amid the flurry of hydrogen announcements from Toyota and Honda last night, Volkwagen has something to add: a new hydrogen fuel cell concept vehicle. This will be the first VW hydrogen fuel cell vehicle in many years – remember the Tiguan Hy-Motion back in 2008? – and it comes as a bit of a surprise. First written up by the German publication Wirtschaft Woche, VW is going to have the prototype car (not pictured) available at the ride and drive at the Los Angeles Auto Show later this week. We don't yet know what kind of vehicle will sport the hydrogen powertrain, but our money's on a Golf variant. We'll see soon enough when we get to Los Angeles. What's interesting is that there have been a number of not-so-mixed messages out of the VW executive ranks when it comes to hydrogen vehicles. VW's Japanese president, Shigeru Shoji, said in September that, hydrogen fuel cells, "may fly within Japan, but not globally." Last year, VW's electrification head Rudolf Krebs said that "hydrogen mobility only makes sense if you use green energy." Also last year, VW CEO Martin Winterkorn said it's basically impossible to build hydrogen vehicles at a "reasonable cost." Nonetheless, we're going to see a new VW H2 concept soon. Thoughts?
