電池電源装置

Japanese Patent JP4117653

B2

As described above, with the present invention, the temperature, voltage and current are detected at a plurality of locations of the battery pack and the operating condition of the batteries is ascertained by means of the SOC calculated from the detected values. By reporting this operating condition to the device that uses the battery power source device, the battery power source device is controlled to an appropriate charging/discharging power. Also, since a failure of the battery pack can be detected from the detected values, measures to deal with the failure can be rapidly implemented. Consequently, when this battery power source device is used as a power source, it is capable of always supplying stable battery power and can rapidly cope with failures, so the present invention is useful in aiming for stable operation of devices using a battery power source device.
