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.

Volkswagen loses thousands of vehicles in Chinese explosion

Yesterday, a blazing, explosive fireball erupted from a port in the city of Tianjin, in China, lighting up the night sky and shattering windows with the force of 21 tons of TNT. Hundreds were injured and the death toll continues to rise, with the most recent reports claiming 50 were killed. While the human cost of this tragedy simply can't be overstated, it hasn't taken long for corporations to look into what the enormous explosion cost them. And for Volkswagen, the answer is quite a lot. According to our friends at Jalopnik, a Chinese source claims the German giant, which remains one of the PRC's most popular brands, lost thousands of vehicles. The automotive casualty sheet lists 1,065 Touaregs, 391 Beetles, 257 Tiguans, 114 Golfs, 84 Up! minicars, 39 SportVans, and 28 Magotans (a locally built version of the Passat). While those are the only vehicles listed, the Chinese source said over 2,700 vehicles were destroyed. For example, both Land Rover and Renault lost an unspecified number of Discovery SUVs and Koleos CUVs, respectively. The explosion also affected Toyota. Its research and design facility with joint-venture partner Sichuan FAW also suffered an unspecified amount of damage. You can check out the translated source article here. As Google Translate jobs go, though, this one is particularly bad, but it still offers some details of the automotive cost of this disaster.

Winterkorn not under official investigation in Germany

Prosecutors for the state of Lower Saxony in Braunschweig, Germany, are now saying that former Volkswagen CEO Martin Winterkorn is no longer specifically under investigation for his role in alleged fraud related to the automaker's diesel emissions scandal. The lawyers are clarifying that there's no formal inquiry into the exec because there's not yet enough evidence to establish a suspicion of wrongdoing, Bloomberg reports. However, they are still looking into VW's actions. Earlier this week, the prosecutors announced they had begun an initial investigation into Winterkorn for alleged fraud in the emissions regulation evasion. At that time, there were reportedly 12 complaints asking the lawyers to look into the case, including one from VW. Under German law, only a person could be charged for the potential crimes, rather than a whole company. "An initial suspicion must be based on facts, and you must begin an investigation before you can establish the facts," Christoph Schalast, a professor at the Frankfurt School of Finance, said to Bloomberg. Meanwhile in the US, the investigation continues into VW. The Department of Justice has the support from at least two senators to pursue criminal and civil charges against the company. The attorneys general in at least 29 states are also looking into things. Meanwhile, lawyers are building a class-action lawsuit, as well. To help in its defense, the automaker is employing the help of the same firm that defended BP during the Deepwater Horizon oil spill. Related Video:
