[PROBLEM] To improve driving performance of a vehicle on which an assembled battery is mounted. [SOLVING MEANS] A battery system includes a motor serving as a driving source for driving a vehicle, a high capacity type of assembled battery and a high power type of assembled battery each capable of supplying a power to the motor, and a controller controlling charge and discharge of each of the high capacity type of assembled battery and the high power type of assembled battery. The high capacity type of assembled battery has an energy capacity relatively larger than that of the high power type of assembled battery. The high power type of assembled battery can achieve charge and discharge with a current relatively larger than that of the high capacity type of assembled battery. The controller causes the high capacity type of assembled battery to be discharged continuously. The controller controls charge and discharge of the high power type of assembled battery such that the SOC of the high power type of assembled battery is matched with a predetermined value while the high capacity type of assembled battery is discharged continuously. The controller causes the high power type of assembled battery to be discharged continuously such that the SOC of the high power type of assembled battery becomes lower than the predetermined value while the high capacity type of assembled battery is not discharged continuously.
