Norwegian winter proving too much for some Tesla charging cables

Polar vortex 1, Tesla Model S 0? Possibly. Norway is certainly a long way from the sunny California climes where the luxury electric vehicle is made and, while the cars are popular in that country, the country's cold weather is creating problems for car owners, the Norwegian website News in English reports. As winter has set in, a number of Model S owners are reporting charging problems. One driver was stranded with a dead battery on Christmas Eve, while others have said Tesla's recharging cables are having a hard time holding a charge when the temperature gets substantially below freezing levels. Tesla has acknowledged that Norway has a different kind of electric grid than the US (and not just because it's 99 percent hydro-powered) that could be causing the problem. The company has reportedly sent Norwegian owners country-specific updates for the on-board recharging software. Once charged, the Model S works just fine in Norway. In this December video, posted by Norwegian Model S owner Bjorn Nyland, a Model S manages to drive for about 233 miles on a single charge in temperatures that reached only about 21 degrees Fahrenheit, and even then the car had about another 25 miles worth of juice left. Tesla has been well-received in Norway in part because of extensive government incentives as well as perks such as bus-lane access and free parking.

Tesla open-sources all its patents

When Tesla CEO Elon Musk says that he's thinking about something, you definitely need to pay attention because it's likely something big. In an eloquently worded press release (a very rare thing indeed) Musk explains reason after reason why Tesla is opening up all of its patents, effective immediately.
According to the missive, Tesla initially applied for patents on its technology because it was afraid bigger, more powerful automakers would take its ideas and destroy the tiny automaker. However, that hasn't happened. Musk claims that while the company has grown, "electric car programs (or programs for any vehicle that doesn't burn hydrocarbons) at the major manufacturers are small to non-existent." At the same time, the global auto industry continues to grow, and Tesla's main competitors aren't from other electric carmakers, but the traditional internal combustion engine.
Musk claims that if you walk into the company's lobby right now all of its patent forms are gone from the walls. "We believe that Tesla, other companies making electric cars, and the world would all benefit from a common, rapidly-evolving technology platform," he writes.

Nissan edges out Tesla for most ZEV credits sold in California

When it comes to California zero-emissions vehicle (ZEV) credits last year, Nissan was selling and Mercedes-Benz was buying. The California Air Resources Board (CARB) put out its ZEV-credits numbers for the year that ended September 30, which is why we now know that Nissan, maker of the battery-electric Leaf, transferred 663.6 ZEV credits out of its account last year. That just edged out the 650.195 credits that Tesla sold. Chrysler's Fiat affiliate was a distant third, but its limited-production Fiat 500E was still able to generate some ZEV credits and then transfer out 235.2 of them. We don't know how much the buyers paid for these credits, since those details are kept private. It's an ever-changing rulebook over at CARB, anyway. On the flip side, Mercedes-Benz had to buy 663.6 ZEV credits in order to comply with clean vehicle-sales mandates in the most populous US state, indicative of the German automaker's gas-guzzling tendencies. Honda has cars that get better fuel economy than your average Benz, but its plug-in vehicles represent just a fraction of total sales and so it had to shell out for 542.5 ZEV credits. Chrysler-Fiat basically tread water, since the 237.8 ZEV credits it required for compliance canceled out gains on the other side of the ledger. Those Dodge Ram pickup trucks don't exactly help matters. Last year, Tesla sold the most ZEV credits while GM purchased the most. Overall, Californians bought about 3.5 million vehicles for the year that ended September 30, including 38,000 battery-electric vehicles, 30,000 plug-in hybrids and 570,000 conventional hybrids. The longstanding ZEV program means that California now has more than 100,000 ZEVs on its roads. Read this for more details on ZEV credit transfers in California.
