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.

Recharge Wrap-up: VW exec predicts EVs with 375-mile range

Volkswagen says EV ranges over 300 miles aren't too far in the future. Plug-in hybrids are merely a bridge to all-electric mobility becoming more practical for people who need to travel longer distances, according to Dr. Heinz-Jakob Neusser, Volkswagen's head of powertrain development. Energy density is increasing rapidly in new batteries. Speaking about the e-Golf, Neusser says, "I expect the next generation in 2015-17 will increase to around 300 km [186 miles] and the following step will be around 500-600 km [310-372 miles]." Neusser also says he believes that charging infrastructure will improve to catch up with these more advanced batteries. Read more at Motoring. BMW is offering higher incentives for the all-electric i3 than the range-extended version. More buyers are opting for the i3 REx, with its 78 extra miles of range. So, to move the standard i3 (which is already cheaper), BMW is offering $2,000 in incentives for October - double what is offered for the i3 REx. The added incentives help close the price gap between the BMW and other EVs with similar ranges. The deals won't last long, though. According to New Jersey BMW salesman Manny Antunes, BMW's current incentives are "as aggressive as they're going to get" for a while. Read more at Green Car Reports. Honda is changing its research and development process for all cars after a series of Fit Hybrid recalls. The hybrid version, which makes up more than half of all Fit sales in Japan, was the subject of four recalls within nine months. In response, Honda will change the way it develops cars worldwide, with one extra "gate" to pass in the process. Honda will do prototype testing earlier in the research process to see how separately developed components work together before moving onto the car's development phase. It will add time and cost to making cars, but Honda hopes it will help prevent problems - like those that come with a flurry of recalls - down the road. Read more at Automotive News.

Volkswagen rules out more potent Polo R

Volkswagen may be planning ever more powerful versions of its Golf, but don't expect that lust for power to trickle down to the smaller Polo anytime soon as the German automaker has reportedly ruled out the prospect of making a Polo R. This according to Autovisie, the automotive section of Dutch newspaper De Telegraaf, in speaking to VW representatives at the launch of the new Polo GTI. Where the previous Polo GTI offered 177 horsepower, the new one packs 189 and is available with either a six-speed manual or seven-speed dual-clutch transmission. The company briefly offered a Polo WRC Street with 220 horsepower, but that was only for a limited edition that Autovisie says will not be repeated for mainstream production. Which may just be for the best, as far as we're concerned, as no versions of the Polo are offered in the US, and we don't need yet another piece of forbidden fruit we can't get our hands on. The decision may seem at odds with the Polo R WRC rally machine with which Volkswagen has been dominating the World Rally Championship for the past two seasons, but was likely made in order to keep the Polo from infringing on Golf territory. VW currently offers the Golf GTI with 210 horsepower and the Golf R with 292, and showcased an even more powerful version with nearly 400 hp.
