Abstract
The present invention relates a battery control apparatus (,) controls charge/discharge processes of a battery (,) installed in a hybrid vehicle, according to the battery temperature so as to prevent degradation of the battery performance. The vehicle has a combustion engine (,) for providing a driving force, an electric motor (,) for generating a drive assist force for assisting the output of the engine, wherein the battery supplies electrical power to the motor, and, when the drive-assist force is not required by the engine, the motor is used as a generator to charged the battery, the apparatus is comprised by: a residual battery charge computation device (,) for computing a level of residual battery charge in the battery; a battery temperature measuring device for measuring a temperature of the battery; and a charge/discharge controller (,) that operates in such a way that, when a battery temperature measured by the battery temperature measuring device exceeds a threshold temperature, the charge/discharge controller permits only discharging until the residual battery charge is lowered to a level defined by a first specified value.
