Level 2 chargers stop at 7kW for single phase and 22kW for 3 phase. That’s fine for home or destination charging but woefully inadequate for long trips.
Beyond that you need to switch to DC chargers that go directly into the battery pack. This is where it starts to get complicated as different battery architectures need different voltages and max currents.
Incorrect, at least for the US, might be different in different areas. 7kW is very common but not the limit for single-phase. J1772 can handle up to 80A/240V which would be 19.2kW of power. A Tesla Model S has a 17kW charger, so it can pull up to ~70A of power on single-phase 240V. A Mach E has an 11kW charger. A Hyundai Ioniq 5 has a 10.2kW charger on board.
This doesn't change the fact this charging speed for Level 2 charging is inadequate for long road trips. Just wanting to share that level 2 charging on a single phase can be higher than 7kW.
