To provide a battery control device capable of inhibiting deterioration of a battery by properly determining a deteriorated condition of the battery.SOLUTION: A battery control device according to the present invention controls a charging/discharging operation of a battery formed of a nickel hydrogen battery. The battery control device includes control means for, in a case where a temperature of the battery is less than a prescribed temperature and the total voltage of the battery is less than a prescribed voltage, charging the battery until the total voltage of the battery reaches the prescribed voltage, and, in a case where the temperature of the battery is less than the prescribed temperature, the total voltage of the battery is equal to or greater than the prescribed value, and a positive electrode potential of the battery is less than a prescribed potential, charging the battery until the positive electrode potential of the battery reaches the prescribed potential.SELECTED DRAWING: Figure 2 【課題】バッテリの劣化状況を適切に判断してバッテリの劣化を抑制可能なバッテリの制御装置を提供すること。【解決手段】本発明に係るバッテリの制御装置は、ニッケル水素電池により構成されるバッテリの充放電動作を制御するバッテリの制御装置であって、バッテリの温度が所定温度未満であり、且つ、バッテリの総電圧が所定電圧未満である場合、バッテリの総電圧が所定電圧になるまでバッテリを充電し、バッテリの温度が所定温度未満であり、且つ、バッテリの総電圧が所定値以上であり、且つ、バッテリの正極電位が所定電位未満である場合には、バッテリの正極電位が所定電位になるまでバッテリを充電する制御手段を備える。【選択図】図２
