Abstract
A power controller alleviating change of braking feeling caused by reduced regenerative braking force is provided. Energy generated by regenerative braking is used for charging a capacitor. The charging power P(C) is calculated and whether P(C) has reached a maximum value WMAX of predetermined limit control value WIN(C) or not is determined. If P(C) is determined to have reached WMAX, WIN(C) is regulated to be smaller from that time point.
