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.

Latest Volkswagen Transporter shows itself as the modern Microbus

With a model history dating back to 1950, the newly unveiled Volkswagen Transporter has a long legacy to uphold as one of elder statesmen of the commercial vehicle world. The sixth generation maintains the classic boxy look, and VW even admits that the shape is "modernized cautiously." Still, the changes show handsome improvements like creases in the hood and a grille that better integrates into the headlights. Rather than styling, economy is more on the minds of many commercial buyers. VW ticks that box with an average 15-percent improvement in fuel consumption across the lineup, thanks in part to standard stop/start. The engine range includes a 2.0-liter diesel four-cylinder available in 83-, 101-, 148- and 201-horsepower variants. There's also a 2.0-liter gasoline-fueled four with either 148 hp or 201 hp. VW is really working to make the Transporter a safer, more comfortable carrier for its new generation. The van is available with features like adjustable shocks, adaptive cruise control, a power tailgate and the company's City Assist Braking system, which is capable of automatically bringing the van to a stop from under 19 mph. The Driver Alert System even monitors behavior behind the wheel and advises when to take a break. VW offers the T6 in many variants, including the Multivan for carrying people and mixed use Caravelle, but the highlight at launch is the fantastic looking Generation Six special edition (pictured above). Based on the Multivan Comfortline, the retro, two-tone paint is optional, but standard features include LED headlights, chrome trim and Alcantara seats. While the latest Transporter isn't coming to the US, European buyers can order one soon with a base price of 23,035 euros ($27,000). Generation SIX: world premiere of the new T series Classic Transporter design is even sharper, more precise, higher end Better fuel economy – new engines with stop/start function as standard Better safety – latest driver assistance systems More comfort and convenience – adaptive chassis, electrically adjustable seats and electric tailgate More information – new radio-navigation system with integrated online services Prices start below level of previous model Hannover/Amsterdam, 15 April 2015 – Today, the Volkswagen Commercial Vehicles brand presents the sixth generation of the successful Transporter model series that is produced in Hannover.

New European charging network will offer speeds up to 350 kW

It's about to get easier to fast-charge your electric vehicle across Europe thanks to four major automakers working together in a new joint venture. BMW, Daimler (Mercedes-Benz), Ford, and the VW Group (Audi and Porsche) have all signed a Memorandum of Understanding to install about 400 DC fast charging sites in Europe. As you may know, there are different types of fast chargers, but the ones that this group is talking about installing will be able to charge an EV in much less time than other stations. That's because these chargers will offer power levels of "up to 350 kW." Compare that to what's generally considered the current gold standard, the Tesla Superchargers, which have rates of up to 145 kW and a statement not that long ago from a Ford exec that suggested that 150 kW chargers would be the new normal. Of course, the Tesla chargers use the company's proprietary connector and the new network the JV is setting up will use the CCS standard. The first new stations will go up in 2017 and those 400 sites are just the beginning. A joint statement by the JV says that EV drivers will "have access to thousands of high-powered charging points" by 2020 along highways and main roads. "The charging experience is expected to evolve to be as convenient as refueling at conventional gas stations," the companies said. While not every electric vehicle will be able to take advantage of the 350 kW charging rate, the companies involved would be silly to build the infrastructure without vehicles that can handle that kind of energy flow. The JV says it would welcome participation from other automakers and will cooperate with interested regional partners.
