Abstract:
1. A battery temperature control system that carries out temperature rise control to raise temperature of a battery mounted in a vehicle by internal heating due to charging and/or discharging of the battery, the battery temperature control system comprising: current detecting means for detecting a current of the battery; voltage detecting means for detecting a voltage of the battery; temperature detecting means for detecting a temperature of the battery; maximum chargeable/dischargeable current setting means for setting a maximum chargeable current and a maximum dischargeable current based on the detected current, voltage, and temperature of the battery; and temperature rise controlling means for controlling charging/discharging power so that the current of the battery does not exceed the maximum chargeable current or the maximum dischargeable current thereby to raise the temperature of the battery; wherein the temperature rise controlling means compares the maximum chargeable current and the maximum dischargeable current with each other, selects the current larger in absolute value, and controls the charging/discharging power thereby to attain the selected current.
