Battery Control Apparatus And Battery Control Method

Abstract: A battery control apparatus and a battery control method are disclosed. The battery control device according to an embodiment of the present invention comprises: a measurement unit for measuring a voltage of a battery to output a voltage measurement value indicating the measured voltage; a memory for storing multi stage charging protocol data comprising a first charging rate, a second charging rate used for another constant current charging procedure subsequent to a constant current charging procedure using the first charging rate, and a first reference SOC associated with the first charging rate; and a processor for identifying an SOC of the battery on the basis of the voltage measurement value. The processor: performs a temporary discharging procedure when the SOC of the battery reaches the first reference SOC while the constant current charging procedure using the first charging rate is performed; determines an adjusted second charging rate different from the second charging rate on the basis of discharging information of the temporary discharging procedure; and performs a constant current charging procedure using the adjusted second charging rate after termination of the temporary discharging procedure.
