Abstract:
A control circuit of a battery branch in a battery system is provided. The control circuit includes a relay unit, a switch unit and a control unit. The relay unit is coupled to the battery branch. The switch unit is coupled in parallel with the relay unit. The control unit is coupled to the relay unit and the switch unit, and is arranged for controlling switching of the relay unit and the switch unit in order to selectively conduct a branch current flowing through the battery branch. A control method of a battery branch in a battery system is provided. The control method includes the following steps: coupling a relay unit to the battery branch, and coupling a switch unit in parallel with the relay unit; and controlling switching of the relay unit and the switch unit in order to selectively conduct a branch current flowing through the battery branch.
