1. a kind of battery cooling apparatus, comprising:

  • Rechargeable battery;

    Blowing unit, by the way that outside air is sent to the battery, the cooling battery;

    Battery temperature detection unit is used to detect the temperature of the battery;

    External air temperature detection unit is used to detect the temperature for the outside air that the blowing unit is sent into;

    AndBattery control unit, if the temperature of the battery is below or equal to setting value, the battery control unit makes instituteBlowing unit is stated to stop working, in which;

    The blowing unit has the function of adjusting wanted air-supply air quantity;

    During blowing unit work, if the outside air that the external air temperature detection unit detectsTemperature is higher than the temperature for the battery that the battery temperature detection unit detects, then described in the battery control unit controlBlowing unit, so that the temperature that the air output of the blowing unit is less than the outside air is below or equal to the electricityThe air output when temperature in pond;

    AndPredetermined time, and the battery control unit are set according to engine workload before the engine stop of vehicleThe blowing unit is controlled, so that the blowing unit is after the engine stop by stopping in a period of the predetermined timeIt only works, and the blowing unit is made to start to work as follows, by described after the engine stop of the vehicleAfter predetermined time and the battery by external charging in the case where, judge whether external air temperature is lower than or waitsIn battery temperature, in the case where judging that the external air temperature is higher than the battery temperature, by the blowing unitThe time interval of discontinuous operation is set as the control time interval longer than normal time interval, is judging the outside air temperatureDegree makes the time interval of the discontinuous operation of the blowing unit from the control below or equal in the case where the battery temperatureTime interval processed reverts to the normal time interval.
