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.

$1.4B hedge fund suit against Porsche dismissed

Investors have canvassed courts in Europe and the US to repeatedly sue Porsche over its failed attempt to take over Volkswagen in 2008 (see here, and here and here), and they have repeatedly failed to win any cases. You can add another big loss to the tally, with Bloomberg reporting that the Stuttgart Regional Court has dismissed a 1.4-billion euro ($1.95B US) lawsuit, the decision explained by the court's assertion that the investors would have lost on their short bets even if Porsche hadn't misled them.
Examining the hedge funds' motives for stock purchases and the bets that VW share prices would fall, judge Carola Wittig said that the funds didn't base their decisions on the key bits of "misinformation," and instead were participating simply in "highly speculative and naked short selling," only to get caught out.
With other cases still pending, the continued streak of victories bodes well for Porsche's courtroom fortunes, since judges will expect new information to consider overturning precedent. If there is any new info, it could come from the potential criminal cases still outstanding against former CEO Wendelin Wiedeking and CFO Holger Härter, who were both indicted on charges of market manipulation.

Recharge Wrap-up: Audi's EV SUV to be built in Brussels, Mercedes-Benz to extend EV range

European Union Industry Commissioner Elzbieta Bienkowska is demanding that Volkswagen compensate owners of cars affected by the diesel emissions scandal. She says European customers should receive the same goodwill compensation as American drivers, whom VW is providing with $1,000 worth of recompense. "The issue of compensation goes beyond the difference in the legal setup between the US and the EU and plays a fundamental role in viewing VW as a responsible and trustworthy company," says Bienkowska in a letter to Volkswagen CEO Matthias Mueller. Bienkowska has also requested detailed data about the vehicles and "corrective measures" VW is planning. Read more from Automotive News Europe. Mercedes-Benz will equip its plug-in vehicles with higher-capacity batteries as it expands its electric model range. While the PHEVs it has released so far have electric driving ranges between 14 and 20 miles, better batteries should extend that range starting around model years 2018 or 2019. After releasing a slew of plug-ins by the end of next year, Mercedes-Benz development director Dr. Thomas Weber says, "The next-generation vehicle will overcome the 30-km to 50-km hurdle and then the next generation after that will be 80-100 km when they run as pure electric cars."

The batteries for the vehicle based on the Audi E-Tron Quattro concept (perhaps to be called the Q6) will also be built at the Brussels plant when production begins in 2018. With this announcement comes news that production of the A1 will shift from Brussels to Martorell, Spain, while Q3 production will move from Spain to Gyor Hungary. Audi says the Brussels facility will "become a key plant for electric mobility at the Volkswagen Group." Read more at Green Car Congress, or in the press release below. Audi production network: ready for electric mobility - Premium manufacturer to produce large series of electric cars in Brussels as of 2018 - New models for Martorell (Spain) and Gyor (Hungary) - Audi CEO Rupert Stadler: "We are increasing our efficiency and bundling key competencies" Audi is preparing its international production network for the mobility of the future. Large series production of the first purely electric driven SUV from Audi will begin at the site in Brussels in 2018. The plant will also produce its own batteries.
