Abstract
A battery control apparatus, a battery control method and an energy storage system including the battery control apparatus are disclosed. The disclosed battery control apparatus includes a first battery pack, a second battery pack, a first switch connected in series to the first battery pack between the first terminal and the second terminal, a second switch connected in series to the second battery pack between the first terminal and the second terminal, and a control unit. The control unit is configured to turn on both the first switch and the second switch when a voltage difference between the first battery pack and the second battery pack at a time point at which both the first switch and the second switch are turned off is less than a threshold voltage.
