If your car has DCFC, then it can take 30 amps at 240 volts (7.2 kW), so a higher amperage station will not improve charging speed. The charger is on board the car. The thing on the wall, the EVSE, will supply what the car requests, up to the EVSE’s maximum output. If you think you may some day have a car that can pull 40 amps, then you could buy a 40 amp station, as they don’t cost much more than a 32 amp station. Also, at home you need to have a properly wired circuit with a breaker at least 1.25x the maximum current the EVSE can deliver (to a car that can take its maximum current output).
