Aren't US homes running at 120 volts? 22kw at 230 volts would be ~95 amps. 22kw at 120 volts would be ~183 amps. 48kw at 120 volts would be 400 amps.

- proto_lambda 4y agoNo, US homes are typically 240V split-phase: https://en.wikipedia.org/wiki/Split-phase_electric_power https://en.wikipedia.org/wiki/Split-phase_electric_power
- goodcanadian 4y agoAren't US homes running at 120 volts? Yes . . . and no. In North America, homes are actually supplied with 240V. A split-phase system with a centre-tap transformer is then used to create two 120V "phases." So, your typical outlets will be on one of two 120V phases. However, there are usually a couple of 240V outlets as well for things like electric stoves, and clothes dryers. So, in short, single phase 240V is available in essentially every U.S. household. The cars, themselves, usually require 3-phase 240V to do 22kW. You are highly unlikely to have access to that in a U.S. home.
