Tesla bucks industry standard with new charging system for Model S
At a time when most EV manufacturers are converging toward charging station conformity, Tesla is still marching to the beat of its own drum. Late last month, the company unveiled a new plug and charger that looks notably different from the J1772 connector -- the SAE International standard you'll find on most electric cars, including the Chevy Volt and Nissan Leaf. The new system, which will be available for the upcoming Model S, consists of a lightweight plug and wall-mounted unit that can supply 240 volts at up to 80 amps. It also features a comparatively thin cable that promises to deliver fast charging at 480 volts, which, according to the company, should give the Model S an extra boost. When connected to a 240 volt outlet, the car will be able to re-juice at a rate of 62 miles of travel per hour of charging. And while its streamlined aesthetics may signal a shift away from the J1772, Tesla's new charger does feature standard connectors for 120 volt and 240 volt outlets, and will ship with an adapter for industry standard plugs. So why did the manufacturer choose to ignore the J1772? CEO Elon Musk certainly has his reasons. Speaking to the New York Times, Musk poetically described the standard connector as "absolutely terrible, extremely ugly and low power." Tesla's system, by contrast, is more like "a beautiful advanced alien artifact that arrived in the middle of the night." He then went on to say how he really feels.

Ford Focus Electric confirmed to not support fast charging, EV fragmentation looms large
Thought that fragmentation was reserved for the mobile OS realm? Think again. With the first (and second) waves of electric vehicles dribbling out to the streets, an obvious problem is becoming even more obvious. The city of Chicago is fixing to install 73 fast-charging EV stations by the end of the year, but two of the most commonly driven ones won't be able to take advantage. Chevy's Volt and Ford's Focus Electric will only support the slower Level 2 charging, leaving those faster ones for Nissan Leaf and Mitsubishi i MiEV owners to enjoy. As if that weren't headache-inducing enough, a slew of other automakers are reportedly planning to "sign on to a new standard for fast charging that would be incompatible with Chicago's infrastructure," and if you think the Windy City is alone in this mess, you're wrong. We've already heard of similar issues in the nation's capitol, and Jack Pokrzywa, manager of global ground vehicle standards for SAE International, still doesn't seem convinced that auto producers are really ready and willing to commit to a single fast-charging standard. HD DVD vs. Blu-ray was one thing, but thousands of vehicle chargers crowding up our cities once they become obsolete in a year? That's so not green.
SAE and Zigbee team up to make plug-in cars charge smarter
We're no strangers to Zigbee around these parts, using the various Alliance-certified devices to monitor our power usage and let our refrigerators talk to our washing machines. Soon our cars might be able to get in on that little conversation with the Zigbee Alliance and SAE International starting to work together. SAE develops standards and certifications in the automotive industry (amongst many others) and it embracing Zigbee Smart Energy means that we should see many more auto manufacturers adopting this tech to enable their cars to talk to the grid straight through their plugs. They'll be able to do things like provide charging status updates and to pull down utility pricing information, ensuring your ride charges when rates are lowest. Many current and most upcoming electric cars can do this sort of thing, but they rely on wireless data connectivity to do so. Zigbee would eliminate that. No word on which manufacturers will jump on first, but given the pull the SAE has we think many will.
