A charging station includes a plurality of charging sockets, each of which is adapted to be connected to an electric-powered vehicle, and a plurality of switch units, each of which includes a relay switch that interconnects a power supplying circuit and a respective charging socket, and a trigger member connected to the relay switch and controllable so as to control in turn the relay switch to make or break electrical connection between the power supplying circuit and the respective charging socket. A current monitoring unit generates output signals corresponding to amount of current flowing through each of the charging sockets. A processing unit receives the output signals from the current monitoring unit, and controls the trigger members of the switch units to ensure the total amount of current flow through the charging sockets does not exceed a rated current value for the charging station.
