Abstract

A battery control apparatus and a battery control method are disclosed. The battery control apparatus according to an embodiment of the present disclosure includes a measuring unit for measuring a voltage of a battery and outputting a voltage measurement value representing the measured voltage, a memory for storing a multi-stage charging protocol data including a first current rate, a second current rate used in another constant current charging procedure following a constant current charging procedure using the first current rate, and a first criterion SOC associated with the first current rate, and a processor for identifying a SOC of the battery based on the voltage measurement value. The processor performs a temporary discharging procedure, when the SOC of the battery reaches the first criterion SOC while the constant current charging procedure using the first current rate is in progress, determines an adjusted second current rate different from the second current rate, based on discharging information of the temporary discharging procedure, and performs a constant current charging procedure using the adjusted second current rate, after the temporary discharging procedure is finished.
