Abstract
A vehicle driven by a motor includes: a secondary battery configured to supply an electric power to the motor; a power regeneration portion configured to supply, to the secondary battery, a regenerative electric power that is recovered at a time of braking the vehicle; a power storage amount detecting portion configured to detect a power storage amount of the secondary battery; and a controlling portion configured to control charging and discharging of the secondary battery. The controlling portion estimates a regenerative electric power, and estimates an expected power-storage increasing amount, so as to calculate a virtual power storage amount from a sum total of the expected power-storage increasing amount and an actual power storage amount. The controlling portion performs charging and discharging on the secondary battery based on the virtual power storage amount.
