SYSTEM AND METHOD FOR CONTROLLING CHARGING AND DISCHARGING OF BATTERY

A system and method are provided for controlling charging and discharging of a group of batteries connected in parallel. A battery charging/discharging control system includes a first battery group comprising one or more first batteries connected in parallel, a second battery group connected in parallel with the first battery group and comprising one or more second batteries connected in parallel, and a charging/discharging controller to generate a first current pulse and a second current pulse, different from the first current pulse. The charging/discharging controller supplies the first current pulse and the second current pulse to the first battery group and the second battery group to control charging/discharging.
