<p>A battery managing control unit (1) detects and computes a battery current and a battery voltage. The comparison means of the battery managing control unit (1) respectively compares the charge current of a charger (11) calculated by a charger control unit (19) with a battery current, and the charge voltage calculated by the charge control unit (19) with a battery voltage. The battery managing control unit (1) calculates the residual capacity of a power supply (10), detects the device for abnormality, and so forth, based on the comparison result of a current and that of a voltage.</p> |
