Abstract:
1. A battery control apparatus for controlling first and second rechargeable batteries, the apparatus comprising: a common bus connecting the first and second rechargeable batteries; a voltage detector configured to detect voltages of the first and second rechargeable batteries; a temperature detector configured to detect a temperature of the first and second rechargeable batteries; a charger/discharger configured to connect to the first and second rechargeable batteries, and charge one of the first and second rechargeable batteries by electric power discharged by the other of the first and second rechargeable batteries; and a controller configured to control the charger/discharger such that charging and discharging are performed between the first and second rechargeable batteries by using the charger/discharger if battery temperature information detected by the temperature detector is lower than a preset threshold temperature, wherein the charging is stopped and switched to discharging or pause if voltage information detected by the voltage detector reaches an upper limit voltage of the one of the first and second rechargeable batteries, and the discharging is stopped and switched to charging or pause if the voltage information detected by the voltage detector reaches a lower limit voltage of the other of first and second rechargeable batteries.
