ABSTRACT:
A battery charging-discharging control apparatus includes an estimation circuit, a detection circuit, and a control circuit. The estimation circuit estimates an internal resistance of a battery. The detection circuit detects a charging-discharging current of the battery. The control circuit predicts a behavior of a voltage of the battery based on behaviors of the internal resistance and the charging-discharging current of the battery. The control circuit limits the charging-discharging current or a charging-discharging power of the battery based on the predicted behavior of the battery voltage in such a manner that the battery voltage is within a predetermined voltage range.
