A hybrid vehicle comprises a motor driving the vehicle's wheels, multiple batteries supplying electric power to the motor, and a generator driven by an internal combustion engine to generate electric power for charging the batteries. Battery sensors detect terminal voltages of the batteries. An ECU controls a DC/DC converter to distribute electric power to independently charge the batteries through charge lines in accordance with the shortage of charge in respective batteries when excess electrical power is available from the generator even after a required amount of electrical power from the generator is used to rotate wheels.
