It is intended to prevent degradation of battery cells (cells). A battery control apparatus obtains a cell voltage value of each of the cells (201) (S1), calculates a cell SOC at each of the cells based on the measured cell voltage value (S2), calculates an integrated current value (Ah) by integrating current values of a battery pack (2) configured with a plurality of the cells (201), calculates a cell capacity value of each of the cells (201) based on the integrated current value and the cell SOC (S3), calculates a dischargeable cell capacity value from the cell capacity value and the cell SOC (S4), and controls charging/discharging of the battery pack (2) based on the dischargeable cell capacity value (S5).
