Chevy is betting big on its electric car, which has an EPA rating of 60 miles per gallon. It also boasts 10 million lines of software code and its own IP address. But it’s the little things that count, including OnStar MyLink, the world’s first mobile app for an electric vehicle. Now, from your Blackberry Storm, Droid, or iPhone, you can check information such as battery charge and electric range, and you can even decide what time to commence charging, so you can take advantage of off-peak rates. The OnStar app can also alert you via e-mail or text message to let you know when charging is complete. And if you hate getting into a cold car on a winter’s day, OnStar lets you pre-heat the interior before you get in, drawing power from the grid instead of your battery.
