In the US there is J1772 that works on everything and it works with 120v - 240v up to 80 amps (though typically 40 max). The US has settled on CCS type 1 for fast DC charging, most new cars support it. There is CHAdeMO a Japanese standard but that connector is on its way out in the US. And then Tesla does it's own thing but there are adapters available. I think it is a solved problem, if you don't want a Tesla a modern EV will have a CCS plug that fits both CCS and J1772. And if you want a Tesla you either get adapters or use Tesla's chargers.
