General Motors just announced today that they’ll be selling a 240-volt home charging unit for its Chevy Volt for $490 (U.S.). The company claims that the unit will let a homeowner charge up the car’s battery in four hours compared to about 10 if you just use a standard 120 volt outlet. Oh, but here’s the catch: It will cost you $1,495 to install. Ouch! That stings.
I’m pretty sure I wouldn’t buy one. I mean, overnight charging gives you plenty of time, and why put stress on your local distribution node by slurping up more than twice as much electricity in a shorter period? I imagine in a couple of years the price of these chargers will also fall significantly. Better to wait.
