An initial output of a secondary battery on an electrically propelled vehicle is set to a value which is at least the sum of an established power output of a motor, an output reduction due to the memory effect of the secondary battery, and an allowable output reduction due to aging of the secondary battery. Since the established power output of the motor is determined taking into account the output reduction due to the memory effect and the output deterioration due to the aging, a minimum power output which the battery has as its capability is prevented ...
