BATTERY CONTROL APPARATUS AND METHOD
First Claim
1. A battery control apparatus provided in a vehicle battery pack, for controlling the battery pack, which can be charged in an emergency and equipped with an auxiliary battery, the battery control apparatus comprising:
- an emergency charging unit including an external charging terminal for applying power to a main battery pack, a first voltage measurement unit for measuring the voltage of the external charging terminal, and an emergency charging switch for switching the connection between the external charging terminal and the main battery pack;
an auxiliary battery connection unit including an auxiliary battery connection terminal for applying power to the vehicle through a contactor, a second voltage measurement unit for measuring the voltage of the auxiliary battery connection terminal, and an auxiliary battery switch for switching the connection between the auxiliary battery connection terminal and the contactor; and
an emergency control unit for switching to an emergency charging mode by turning on the emergency charging switch during the voltage measurement of the first voltage measurement unit and switching to an auxiliary connection mode by turning on the auxiliary battery switch during the voltage measurement of the second voltage measurement unit.
