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.

2015 Volkswagen Touareg [w/video]

The second-generation Volkswagen Touareg has been in production since 2010, and is therefore staring down the last part of its model cycle. To keep buyers interested, the company has undertaken a refresh of its upscale midsize SUV. As is typical of these things, the changes include some exterior and interior rejuvenation, as well as increased content levels and a slight uptick in price. The basics of the styling changes are pretty straightforward. The 2015 Touareg can be pretty easily spotted versus the outgoing model by way of its four-bar chrome grille, a cleaner headlight design, bigger VW badge and a completely new lower front clip. (I got one photo of the old and new models side-by-side for my Twitter followers before we rolled out on the drive.) There's also a thin strip of chrome that runs around the bodywork, standard LED taillights and a selection of three new wheel styles and five new paint colors. Inside, I found it harder to spot the changes, old to new. The Touareg's switchgear has been updated and there's a new frame for the infotainment display, but there's no piece that stands out and says "new model year!" Powertrains and mechanical bits all carryover from the 2014 Touareg, too. But there were a few functional changes to the vehicle, primarily in the new Driver's Assistance Package, for me to take note of as I took a lap of my favorite Ann Arbor, MI driving route. Drive Notes Let me start with the newest news then, the Driver Assistance pack. Volkswagen will sell you this suite of safety gear on either the mid-level Lux or the top-end Executive trims, for $2,500. The package included adaptive cruse cruise control, "Front Assist" for emergency braking situations, lane-keep assist and blind spot monitoring. If the contents of that package don't strike you as revolutionary, you're not alone. Some or all of the technologies that are new to the Touareg have been around other showrooms – and other VW family products – for quite a while. Still, they're nice to have as options. All of the driver assistance features that I was able to test worked as advertised, too. The adaptive cruise uses cameras, radar and ultrasonic sensors, so it isn't likely to be impacted by inclement weather, which is nice. I also appreciate that the lane-keep assist (which offers the driver a haptic buzz to the steering wheel when straying out of the lane) can be turned off, or turned down in terms of intensity and reaction time.

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.
