That seems really weird; I'd expect that the big charging station you install in your garage would convert from home AC into some high-current DC. Batteries don't actually charge on AC, do they?
- tyingq 9y agoNot directly, no. But electric vehicles convert AC since that what consumers have easy access to. And their rectifiers expect nice sine waves.
- camiller 9y agoI think some of the newer one have a high speed DC charging option. I think the Chevy Bolt has a DC option.
- pinkythepig 9y agoJ1772 plug (the one that every EV has) is an AC connection and there is a converter in the car that converts it to DC. The super charge ports (CHAdeMO/CCS/etc) use DC power and are basically direct hookups to the battery. https://en.wikipedia.org/wiki/SAE_J1772 https://en.wikipedia.org/wiki/SAE_J1772 https://en.wikipedia.org/wiki/CHAdeMO https://en.wikipedia.org/wiki/CHAdeMO
