Abstract
Provided is a vehicle battery-pack equalization system (), wherein, in a battery pack () to be mounted on a vehicle, and which is comprised of a plurality of unit cells () connected in series, each of the unit cells () are made to be discharged to equalize the voltages thereof, or the remaining capacities (SOC) thereof. The equalization processing time of each of the unit cells () is set to a period of time the result of multiplying the discharging time of the battery pack () starting from just before the equalization processing, and the ratio of the difference between the currents discharged by each of the unit cells () with respect to the equalization discharging current. In such a way, power consumption during equalization processing can be inhibited.
