A control apparatus for use in a vehicle for controlling an energy storage device
adapted to discharge electric power that varies with a temperature is provided.
The control apparatus includes a temperature sensor that measures a temperature
associated with the energy storage device, and a voltage control unit that sets
a minimum storage voltage of the energy storage device to a relatively high voltage
level when the temperature measured by the temperature sensor is lower than a predetermined
temperature, as compared with a voltage level to which the minimum storage voltage
is set when the temperature is higher than the predetermined temperature.
