as cars are bigger than the chargers there could be chargers for multiple competing charging standards at the space for one car. If only one charger can be used at a time anyway since only one car can occupy the charging space at a time, then both chargers can share the electric power feed and the overall power delivery to the supercharging station can stay the same despite having double the number of chargers charging the same number of cars.
