Method and device for controlling charging stations for electrical vehicles. In order to minimize peak power demands in at least two charging stations 10 combined into a group 12, actual charging parameters are exchanged 32 within the charging stations 10 within the group 12, a load prediction for the group 12 is created 34 depending on at least the actual charging parameters, and setpoint charging parameters for the charging stations 10 of the group 12 are determined 38 depending on the load prognosis.
