Charge control system, power supply system , charge control method and program

Abstract

The objective of this invention is to control the total amount of electricity supplied to an electric vehicle so that it does not exceed the amount of electricity that can be received from the power source. The charging control system (10) includes an acquisition unit (111), a switching control unit (114), an allocation unit (112), and a selection unit (113). When two or more EV charging devices (3) are assigned a priority, the selection unit (113) selects one or more EV charging devices (3) to be supplied with electricity from the two or more EV charging devices (3) according to each priority, so as to satisfy a predetermined condition. The predetermined condition is that the sum of the rated outputs corresponding to the two or more EV charging devices (3) does not exceed a preset value. The switching control unit (114) controls one or more switches (250) corresponding to the selected one or more EV charging devices (3) to connect them to the power source, and controls other switches (250) to disconnect them from the power source.
