摘要:
A battery power source comprising a cooling device and a large number of battery modules (9), constituted by a plurality of single cells (7) connected in a row electrically and mechanically in series, arranged parallel to each other and held in a holder casing (10) wherein air is forcibly made to flow in one direction within said holder casing (10) thereby cooling the large number of battery modules (9) in said holder casing (10), the direction of flow of the air is in a direction at right angles to the longitudinal direction of said battery modules (9), and wherein means for flow alignment are arranged within said holder casing (10) such that the flow speed of the air flowing through said holder casing (10) is faster on the downstream side than on the upstream side.

摘要:
A battery power source comprises a plurality of battery modules connected in series and arranged in a case in a three-dimensionally parallel arrangement. A resistance for preventing a rush current is interposed in series between the terminals of the battery power source and an external load. A circuit provided with a relay allows to by-pass the resistance.
摘要:
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.
