Kind Code:
A1
Abstract:
The present invention simplifies the circuit configuration related to a converter. This electric power control system is connected to an electric power supply line between a load and an electric power generation device which generates electric power by utilizing natural energy. This electric power control system is provided with: a power storage unit which comprises a lithium ion capacitor and a lithium ion battery; a DC/DC converter; and a charge/discharge control unit which controls charging and discharging of the power storage unit. The charge/discharge control unit controls charging and discharging of the lithium ion capacitor by connecting the lithium ion capacitor to the electric power supply line via the DC/DC converter, and controls charging and discharging of the lithium ion battery by connecting the lithium ion battery to the electric power supply line via the common DC/DC converter.
