Whenever I go somewhere unfamiliar, I like to look around plugshare and get an idea of what chargers are near by and what they might cost. A few months ago, I was out in some tiny town in Indiana. There was only one charger that was charging $0.40 per kWh. Ouch! That's just as expensive as gas. Luckily I wasn't driving out there. I figured they could get away with that rate because they're the only game in town. This weekend I was spending some time in DC. I opened up plugshare and looked at what was near by. There were several chargers that cost $0.55 for "non-members" and $0.45 for "members" of whatever screwed up charging network that was. That is pretty insane, and even more expensive than gas. I've never paid for charging outside my own home. If I ever have to, I hope its not at rates like those!
