We’re slobbering dorks when it comes to cars. We like ‘em an unhealthy amount of course, but when it comes to how things work, we take the British Leyland approach. However, our good buddy Sam at Autoblog Green is an actual engineer that understands math and stuff. Which is how he was able to come up with the following equation, proving that if you were to plug your Telsa into your 110 volt wall socket, it’d take more than a day to fully charge: 53,000W / (110V * 15) = 32.12 hours. Oy vey, as we say. However, Sam provides a solution. Just get an electrician to wire up a 220V/40A circuit. Then your hotshot all electric roadster will be ready to rock in 6-7 hours. [Autoblog Green]
