BATTERY CONTROL APPARATUS AND BATTERY CONTROL METHOD

摘要

The objective of the present invention is to prevent deterioration of cells. A battery control method is characterized in that cell voltage values of each of a plurality of cells (201) are obtained (S1), SOCs of each of the cells are calculated (S2) on the basis of the measured cell voltage values, an integrated current value (Ah) is calculated by integrating the current value of a battery pack (2) that is composed of a plurality of cells (201), cell capacity values of each of the cells (201) are calculated (S3) on the basis of the integrated current value and the SOCs of the cells, cell dischargeable-capacity values are calculated (S4) from the cell capacity values and the SOCs of the cells, and charging/discharging of the battery pack (2) are controlled (S5) on the basis of the cell dischargeable-capacity values.
