ABSTRACT:
There is provided a battery control apparatus that, when the battery temperature is low, repeats the charge and discharge of a battery on a short cycle such that the state of charge (SOC) of the battery lies in the range of 30 to 40% if the present SOC is less than 50%, and repeats the charge and discharge of the battery on a short cycle such that the SOC lies in the range of 50 to 60% if the present SOC is equal to or greater than 50%, thus increasing the temperature of the battery. Therefore, it is possible to increase the battery temperature in an efficient manner, and to prevent the available input-output power of the battery from being reduced due to a decrease in the battery temperature.
