Battery Capacity Recovery Apparatus And Battery Capacity Recovery Method

Abstract: A battery capacity recovery apparatus and a battery capacity recovery method are provided. The battery capacity recovery apparatus comprises: a sensing unit configured to measure a voltage and a current of a battery; and a control unit configured to determine an electrical state of the battery on the basis of time-series data of each of the voltage and the current of the battery. The control unit is configured to sequentially execute a first capacity recovery routine and a second capacity recovery routine upon determining to execute a capacity recovery process on the basis of the electrical state of the battery. The first capacity recovery routine is a procedure for discharging the battery until the SOC of the battery falls to a reference SOC. The second capacity recovery routine is a procedure of resting the battery for more than a reference time from a completion time of the first capacity recovery routine.
