Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.

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.

China sticking to its guns on EVs for the future

Automakers are obviously free to develop whatever next-gen, zero-emissions tech that they want. However, if a company wants to get on the good side of the Chinese government, that strategy better include some plug-in vehicles. The authorities there are lending major support to plug-ins at the moment, and its forcing the auto industry to play along. According to Bloomberg, Toyota, Volkswagen, Hyundai, and BMW are all launching dedicated EV brands with their joint venture partners, and as many as 40 electric models could hit the Chinese market this year alone. However, analysts don't think the vehicles are going to sell well. Instead, the launches are essentially a way for companies to play nice with the government and help get the approval to build factories in the country. Take Toyota as an example. The company is pushing the future of hydrogen hard with promotional films for the Mirai and engineers talking down fast-charging EVs. Still, the Japanese automaker is getting ready to launch two EV brands in China with its joint venture partners, according to Bloomberg. China's push for alternative fuels has been happening for a while, but it really kicked into high gear last year. The government has set a goal to improve fleet-wide economy by 40 percent by the end of the decade in order to spend less importing oil and for the population's health. The plan has shown some success so far with hybrid and EV sales growing early in 2015.
