Abstract
A rotary electric machine () which constitutes a prime bar of a vehicle and an electricity storage device () serving as a main power source of the rotary electric machine () and composed of a plurality of capacitor modules () in which a plurality of capacitor cells make one set are provided. A hybrid control unit () which comprises a means for calculating assigned voltages of the capacitor modules, a means for calculating an average value of the assigned voltages of the capacitor module, and a means for equalizing the assigned voltages of the capacitor modules based on the average value. By restricting a difference among the assigned voltages of the capacitor modules (), it is possible to fully utilize a capacity of the electricity storage device ().
