METHOD OF CONTROLLING CHARGING AND DISCHARGING OF POWER STATION EQUIPPED WITH MULTIPLE BATTERY PACKS

A method of controlling charging and discharging of a power station equipped with multiple battery packs, performed by a power station including N (N is a natural number equal to or greater than 2) battery packs mounted to be electrically charged/discharged and including a main controller controlling the charging/discharging, includes charging, by the main controller, the N battery packs in a determined charge order by controlling N input relay units connecting the N battery packs to an external charge source, and when a load is connected from the outside during the charging operation, calculating, by the main controller, an amount of electricity required by the load, controlling N output relay units connecting the N battery packs to the load to connect battery packs by the number corresponding to the calculated amount of electricity to the load and perform a discharging operation, wherein the charging operation and the discharging operation are performed simultaneously.
