Charging levels - Level 1, Level 2, DC Fast Charging, etc

Charging levels - Level 1, Level 2, DC Fast Charging, etc: "SAE's "Level 1/2/3" Terminology The Society of Automotive Engineers (SAE) is a standards agency overseeing the Automotive Industry. For electric car charging, the SAE convened a committee called "J1772". You may have heard of the "J1772 plug", which some call a "J-Plug", so now you know where the name came from. One thing the J1772 committee developed is this terminology table AC Charging Systems DC Charging Systems AC Level 1: 120 volt single phase AC up to 16 amps, for up to 1.9 kiloWatt charge rate. Typically this is limited to 12 amps. DC Level 1: 200-450 volts DC up to 36 kiloWatts (80A) AC Level 2: 240 volt single phase AC up to 80 amps, for up to 19.2 kiloWatt charge rate. Typically this is 32 amps. DC Level 2: 200-450 volts DC up to 90 kiloWatts (200A) AC Level 3: More than Level 2. A couple car makers make cars supporting three phase AC charging at rates up to 43 kiloWatts. DC Level 3: 200-600 volts DC up to 240 kiloWatts (400A) In AC charging systems, the car has an on-board charger does AC to DC conversion. In DC charging systems, there is instead an off-board AC to DC converter for the AC-DC conversion, and there's a direct connection to battery pack bypassing the on-board AC charging system. This terminology was developed by engineers for talking among engineers. They need this sort of precision. The rest of us don't, really. The phrases above are fairly good, except we do need to distinguish between AC Fast Charging and DC Fast Charging."
