Commercial fast chargers are more like 25kW to 200+kW. Most common is 25 to 75 but the newest are at the top and going up. Compare to Tesla's largest battery at 100 kWh.
Most normal home charging is about 30 amps at 240v for 7kW. About the same as an electric oven. Most new homes are wired with 200 amp service and could support close to 25kW charging but it is generally pointless for overnight charging. Even 80 or 100 amp service can easily support EV charging as the vehicles will charge slower if power is restricted. Even a 20 amp 240v circuit would be more than enough except for maybe an extreme commuter. I recently installed a 30 amp circuit in a rental house with just 100 amp main panel and easily provides 24 amps to the vehicle.
