CHARGE/DISCHARGE CONTROL DEVICE, CHARGE/DISCHARGE CONTROL SYSTEM, CHARGE/DISCHARGE CONTROL METHOD, AND PROGRAM

摘要

An external device information acquisition unit (142) acquires charge identification information from an electric power supply source, and acquires discharge identification information from an electric power supply destination. An electric power amount acquisition unit (144) acquires an electric power amount supplied from the electric power supply source to a secondary battery. An electric power storage state DB (161) associates and stores the charge identification information of the electric power supply source and the electric power amount acquired by the electric power amount acquisition unit (144). A charge/discharge setting DB (162) stores discharge permission information indicating the electric power supply source and the electric power supply destination capable of discharging the electric power charged into the secondary battery from the electric power supply source. A discharge permission determination unit (145) determines, on the basis of the discharge permission information, whether or not the electric power supplied from the electric power supply source identified by the charge identification information stored in the electric power storage state DB (161) is dischargeable to the electric power supply destination identified by the discharge identification information.
