6. Actually all US EVs

can use the J1772 connector for AC charging. It gets problematic when you move up to high power DC quick charging. For that, there are 3 connectors, CHAdeMO, CCS, and Tesla.

CHAdeMO is used with Japanese/Korean cars (Soul, Niro, Kona, Leaf) and currently tops out at 50kW. CCS is used by US cars (Bolt, Mach-E) and EU brands (VW, Volvo, Mercedes, and EU model Teslas). Power is generally in the 100-150kW range, with a few 350kW facilities. CCS is a superset of the J1772 AC standard (1.3kW-11kW). Tesla’s connector is proprietary to Tesla, and there are Level 1 home chargers that will plug into a standard 110v/15A socket. While this works, it would literally take days to recharge a completely depleted Tesla battery. Level 2 charging is 220v/30A-80A. Then there are the Superchargers, which range from 120kW (v1), 150kW (v2) and 250kW (v3). Tesla chargers are fairly common (1,000+ stations in the US), reliable, fast, and reasonably priced.

L1 charging can put about 3 miles per hour back in the battery. L2 depends on the amperage of the circuit. 30A will put about 15 miles per hour, around 25 miles at 60A and 45 miles at 80A.

Quick/Supercharging can restore 80% capacity in 20-45 minutes.

I am running 2 EVs and a PHEV, with a big array and Powerwalls. Please feel free to ask me anything.
