OpenChargeMap is a neat little service designed to help those with electric cars find places to charge up. With gas prices going the way they are, electrics are becoming a trendy alternative, and with the new Chevy Volt and Nissan Leaf offering good choices for the average consumer, more and more people are going electric. If you're one of those, however, there's always a hitch: finding a place to "fill up". Now you're covered and with the OpenChargeMap API you can integrate the service into other things.
