Shouldn't be all that much. The total cars on road-trips, where this charging is used, is the same. Individual charges become bigger spikes but the total load of all those road-trips stays the same. For the cases where the total power is not available (e.g., multiple cars plugged in exactly at the same time) the charging station will just throttle the power like it already happens today in chargers that share a supply. What it does help with is a need for fewer chargers in total to support the same number of cars/charges.
