Abstract
A battery system includes a first battery pack, a second battery pack, a bidirectional power converter, and a current controller. The first battery pack includes at least one first battery cell. The second battery pack is connected to the first battery pack in parallel and includes at least one second battery cell. The bidirectional power converter is connected between the first battery pack and the second battery pack. The current controller sets a discharge current limit of the first battery pack based on a state of charge of the first battery pack and controls the bidirectional power converter to cause the first battery pack to output a discharge current that is less than or equal to the discharge current limit.
