More Information
Summary:LICs are grouped into a plurality of LIC groups. Switches switch a power-feed path to allow charging and discharging to be performed for a combination of the LIC groups. A life diagnostic unit obtains the lives of the LICs. A charge-discharge priority controller sets a priority of each of the LIC groups based on the lives of the respective LICs. A charge-discharge managing unit selects one or more of the LIC groups for which charging and discharging are performed, based on the priority set by the charge-discharge priority controller and supplied power demanded during discharging, and controls the switches to allow charging and discharging to be performed for a combination of the selected one or more of the LIC groups.
