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.

Meet ZelectricBug, the amazing '63 VW Bug converted to EV power

No word a lie, we here at AutoblogGreen are fans of classic cars. What we are not fond of, however, is the pollution that their inefficient engines create, and so it's great to see our old favorites lovingly up-cycled with electric drivetrains. The ZelectricBug is a beautiful example of how new, cleaner life can be breathed into an old Volkswagen Beetle. Now, we first came across this particular automobile during the Refuel event last summer and we were struck by its cleanly done conversion then. Aside from a few snaps in our gallery, though, we didn't give it the kind of attention it deserves. Fortunately, the good folks over at Roads and Rides have rectified this by turning their pro video camera skills onto the 1963 V-Dub and producing a nice little segment to accompany their write up. Scroll below to see the finished footage and head over to their website for some stills. If all this gives you a hankering for your own Zelectric, the company does have plans to sell to the public starting this summer. If you don't want to wait, EV West, the guys who did the drivetrain work on this car, have conversion kits available for Beetles, as well as a number of other vehicles.

VW execs didn't think diesel problem would be so serious

Volkswagen Group has admitted that former chairman Martin Winterkorn received two memos about the diesel scandal in 2014. Top execs ignored the problem because they didn't think it was a serious issue. VW disclosed these details to counter allegations in a German shareholder lawsuit that alleged the automaker violated the law by withholding the info from investors. A memo on May 23, 2014 first advised Winterkorn about emissions cheating. A memo on May 23, 2014, first advised Winterkorn about the study from the International Council on Clean Transportation, which identified the emissions cheating. According to VW, the document was part of the exec's weekend mail, and the company's investigation didn't discover whether Winterkorn actually read it. A rumor last month alleged this memo existed. Another memo for Winterkorn on November 14, 2014 was about several defects, including the diesel engines. The document estimated it would cost 20 million euros ($22 million US at current rates) to fix the problem. The chairman learned about the issue again on July 27, 2015, during a meeting on product issues. "Mr. Winterkorn asked for further clarification of the issue," according to VW's statement. Things got serious at the end of August 2015. Things got serious at the end of August 2015 when technicians explained the diesel issue to the legal department. VW came clean to the California Air Resources Board and the Environmental Protection Agency on September 3. A memo told Winterkorn the next day, which was also previously alleged. According to this investigation, management didn't believe the diesel problem would affect the stock price, and they estimated the cheating might cost at most a few hundred million dollars in fines. The execs were clearly wrong. The share price dropped after the scandal broke last September, and the problems have started to affect its divisions. According to Reuters, Audi reported it suffered 228 million euros ($249 million) in costs in 2015 from the emissions issue and repairing Takata's faulty airbag inflators. Volkswagen still doesn't know the exact costs of the scandal, but the automaker's law firm, Jones Day, plans to release a report in the second half of April to explain the whole affair. By that time, we might also know how VW plans to fix the problem because a judge recently gave the company until March 24 to outline a fix for the 2.0-liter TDI. CARB started evaluating a repair plan for the 3.0-liter TDI in early February.
