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.

Germany says nein to EU ban on new fossil-fuel cars from 2035

BERLIN (Reuters) - Germany's government will not agree to European Union plans to effectively ban the sale of new cars with combustion engines from 2035, Finance Minister Christian Lindner said on Tuesday. In its bid to cut planet-warming emissions by 55% by 2030 from 1990 levels, the European Commission has proposed a 100% reduction in CO2 emissions from new cars by 2035. That means it would be impossible to sell combustion engine cars from then. European Parliament lawmakers backed the proposals this month, before negotiations with EU countries on the final law take place. Speaking at an event hosted by Germany's BDI industry association, Lindner said there would continue to be niches for combustion engines so a ban was wrong and said the government would not agree to this European legislation. Lindner, a member of the pro-business Free Democrats, which shares power with the Social Democrats and Greens, said Germany would still be a leading market for electric vehicles.

BMW, VW partner with ChargePoint for high-speed charging network

To promote their plug-in electric vehicles, a number of electric vehicle makers are working overtime to get a charging infrastructure set up. Tesla is famously setting up a network of Superchargers around the world, and today BMW and VW have announced they are partnering with ChargePoint to install almost 100 DC Fast Chargers up and down the US coasts. Installing additional Level 2 chargers is also part of the plan. The new DC Fast Chargers will offer the SAE Combo connectors, which is available on both the e-Golf and the i3. The fast chargers will have "up to two 50 kW DC Fast chargers, or 24 kW DC Combo Fast chargers," BMW says. They will be installed roughly 50 miles apart between Boston and Washington, DC in the east as well as Portland, San Francisco, Los Angeles and San Diego in the west. The 24-kW DC Fast Chargers will fill up an empty i3 or e-Golf to 80 percent in a half-hour or 3.5-4 hours from the Level 2 cords. Speaking at an announcement ceremony at the Washington Auto Show today, ChargePoint CEO Pasquale Romano said that infrastructure investments like this will get more people to realize that they can use an electric vehicle as their only car, and Jorg Sommer, VP of product marketing and strategy for VW North America, said that it's clear that, "The EV is perfect for the daily driver." BMW, Volkswagen and ChargePoint Join Forces to Create Electric Vehicle Express Charging Corridors on the East and West Coasts. · A goal of nearly 100 DC Fast charging ports will be installed to support long distance and metropolitan electric vehicle travel with the BMW i3, Volkswagen e-Golf and other electric cars, along heavily trafficked corridors on both coasts, supported by Level 2 chargers. · These publicly available charging stations will be added to the existing ChargePoint network and can be easily accessed using a ChargePoint® or ChargeNow card. Washington, D.C., January 22, 2015 – At the 2015 Washington Auto Show, two of the top automakers, BMW of North America and Volkswagen of America, together with ChargePoint, the largest electric vehicle charging network, announced an initiative to create express charging corridors along heavily-traveled routes on the East and West Coasts.
