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.

Porsche tops JD Power APEAL study for 12th time

JD Power's 2016 Automotive Performance, Execution, and Layout (APEAL) study hasn't changed much this time around with Porsche coming in at No.1 for the 12th consecutive year, while BMW was close behind in second. Jaguar and Mercedes-Benz tied for third with Land Rover, Lexus, and Lincoln tied for No.5. The APEAL Study, according to JD Power, measures owners' level of excitement and emotional attachment across 77 parameters. Brands and cars are rated on a 1,000-point scale. The study found that new cars with modern safety features including low speed collision avoidance and blind spot monitoring have higher APEAL scores than vehicles without the features. The overall industry score increased from 798 to 801, which JD Power claims was helped by the launch of a variety of new vehicles. This year, 22 out of 30 new or redesigned cars received a higher score than the vehicle's respective segment average. Porsche is once again at the top of the list as the automaker's score increased by three points to 877. BMW outscored Jaguar to take second place with a score of 859, while the British automaker dropped three points from last year with 852 points. Volkswagen overtook Mini to become the top-ranked non-premium brand with 809 points, while the latter automaker trailed behind by one point. At the end of the scale, Smart came in at the very bottom for the second year in a row with a score of 745 points, which represents an increase of 62 points over last year. Fiat's score increased by six points to 755, but still confined the automaker to second-to-worst place for a consecutive year. Mitsubishi's score increased to 770, up from 755, to become the fourth-worst brand, while Jeep fell to third-worst with a decrease in seven points to 756. General Motors received six segment-level awards, followed by Hyundai with five, and BMW and VW earning four apiece. Surprise segment victories include the Chevrolet Camaro, which outscored the Dodge Challenger, and the Lexus RC which ranked above the BMW 4 and 3 Series.

VW V-Charge is clever automated EV parking, charging tech

Automated parking is another niche that Volkswagen wants to rule, so the German carmaker has teamed up with five technology partners to develop its V-Charge system. In short, V-Charge allows an owner to use a smartphone app to send his car to find a parking space and return when requested. If it's an electric car, it will search for an open inductive charging spot, and when fully charged it won't squat over the charger, but will move to find a conventional parking spot. Valet Charge uses four wide-angle cameras, three stereo cameras, 12 ultrasonic sensors, and car-to-infrastructure protocols to avoid obstacles as it finds its way around, including areas like parking garages where GPS won't work. VW says it's been careful to use off-the-shelf sensors and technologies that are already installed in current cars, since it has an eye on near-term implementation of V-Charge. It's impossible to know what "near-term" means, but the sooner we can avoid the valet and trust our car to fetch a spot and come back to us like a faithful pet, the better. The video above shows it at work, the press release below has all the details. 'V-Charge': Volkswagen pushes development of automated parking and charging of electric vehicles - Parking spaces driven to fully automatically - Electric vehicles charged automatically - V-Charge places only minor demands on car park infrastructure - Intelligent form of valet parking Volkswagen aspires to holding the leading position in the field of automated parking. A look into the near future of automated parking is given by 'V-Charge', an EU research project, in which six national and international partners are jointly developing new technologies. Its focus is on automating the search for a parking space and on the charging of electric vehicles. The best part about it is that the vehicle not only automatically looks for an empty parking space, but that it finds an empty space with charging infrastructure and inductively charges its battery. Once the charging process is finished, it automatically frees up the charging bay for another electric vehicle and looks for a conventional parking space. 'V-Charge' stands for Valet Charge and is pointing the way to the future of automated parking. Wolfsburg, 14 July 2015 - In the USA especially, convenient valet parking is a big hit: you pull up in your car right outside your destination, valet service personnel park it for you and have it brought around again as and when you need it.
