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 finds CO2 'irregularities' for 800k vehicles

The latest issue for Volkswagen affects another 800,000 vehicles, and this time its for irregularities in CO2 emissions certifications. VW estimates this issue could cost the company $2.2 billion to fix. The company officially makes no specific mention of which engines are covered, the models they are in, or even where they are located. VW discovered the situation during its ongoing internal investigation, and, according to the automaker, "it was established that the CO2 levels and thus the fuel consumption figures for some models were set too low during the CO2 certification process." Most of the affected vehicles are diesels, and the company is now reaching out to "the responsible type approval agencies" to figure out the next step. While VW isn't officially confirming which models and engines are involved, Automotive News reports that it affects some 2012 and later VW, Audi, Seat, and Skoda models with the company's 1.4-, 1.6-, and 2.0-liter diesel engines, as well as the 1.4-liter ACT gasoline engine. The issue mainly affects vehicles sold in Europe. "The Board of Management of Volkswagen AG deeply regrets this situation and wishes to underscore its determination to systematically continue along the present path of clarification and transparency," CEO Matthias Muller said in the announcement. Volkswagen Group of America spokesperson Jeannine Ginivan was able to provide some further clarification to Autoblog. "This is not related to US-certified vehicles," she said. Clarification moving forward: internal investigations at Volkswagen identify irregularities in CO2 levels Matthias Muller: "Relentless and comprehensive clarification is our only alternative." Around 800,000 Group vehicles could be affected Initial estimate puts economic risks at approximately 2 billion euros The Volkswagen Group is moving forward with the clarification of the diesel issue: during the course of internal investigations irregularities were found when determining type approval CO2 levels. Based on present knowledge around 800,000 vehicles from the Volkswagen Group could be affected. An initial estimate puts the economic risks at approximately two billion euros. The Board of Management of Volkswagen AG will immediately start a dialog with the responsible type approval agencies regarding the consequences of these findings. This should lead to a reliable assessment of the legal, and the subsequent economic consequences of this not yet fully explained issue.

Suzuki and VW finalize their divorce

The rocky divorce between Suzuki and Volkswagen is finally over after working its way through the International Court of Arbitration since 2011, according to the Japan Times. In the final settlement to end the companies' disputes, Suzuki agreed to pay VW an undisclosed amount for not living up to the agreement to use the German automaker's diesel engines. While they won't disclose the exact sum, Suzuki said in a statement that the money "will not have any significant impact" on its 2015 fiscal year results, which will end in March. The arbitration court took the biggest step to end this transcontinental partnership in August 2015 when the body ruled VW needed sell its 19.9-percent stake in Suzuki. However, the Japanese company wasn't entirely off the hook because VW was still allowed to sue for damages over the diesel engine issue. This latest decision finally clears up that dispute. Like most marriages, the union between VW and Suzuki began with stars in both parties' eyes. The Germans paid $2.8 billion to buy 19.9 percent of the Japanese company in December 2009. VW was supposed to get greater access to the auto market in India, and Suzuki hoped to capitalize on access to its partner's advanced technology. By 2011, rumors started percolating that things were contentious behind closed doors. VW allegedly tried to assert control over Suzuki's operations, and the Japanese company reportedly wasn't happy with its access to the German tech. Suzuki even bought diesel engines from Fiat, rather than VW. Later that year, company CEO Osamu Suzuki announced he would end the alliance, and they started working through arbitration. Notification Concerning Resolution of Arbitration by Settlement As Suzuki has reached a settlement regarding the arbitration that Suzuki filed with the International Court of Arbitration of the International Chamber of Commerce on 24 November 2011, Suzuki informs you of the following: 1. History from the Request for Arbitration to the Settlement As announced in the "Notification Concerning Arbitration Award" dated 30 August 2015, the Tribunal indicated that it would address the issue of alleged damages arising from Suzuki's breach of the agreement claimed by Volkswagen AG ("VW") in a further stage of the arbitration proceedings. Suzuki reached a settlement with VW in regard to such arbitration proceedings on 10 February 2016. Accordingly, the arbitration proceedings have been concluded. 2.
