<p>A battery management control section 1 practices detection and calculation of a battery current and a battery voltage. Also, comparison means of the battery management control section 1 individually compares the charging current of a charger 11 calculated by a charger control section 19 and the battery current, and the charging voltage calculated by the charger control section 19 and the battery voltage. The battery management control section 1 practices calculation of a residual capacity of the electric power source 10, detection of an abnormal device condition and so forth based upon a result of the comparison between the currents and a result of the comparison between the voltages. <IMAGE></p> |
