The cooling fan control operation performed by the cooling fan control unit 16 will be described. When charging is started, the detected values of the battery temperature sensors 12-1, 12-2, 12-n,... Are compared with a preset low-temperature determination temperature to determine whether the battery temperature is low. It is determined whether or not (S10). If each battery temperature is low, then each battery temperature is compared with the ambient temperature (S12). If the ambient temperature is higher than the temperature of each battery, the battery is not further cooled even if the cooling fan is turned on, so that normal fan control is performed (S14). If the ambient temperature is lower than the temperature of each battery, the process proceeds to S20 in order to avoid unnecessary cooling of each battery.

If each battery temperature is not high, normal fan control is performed (S14). If each battery temperature is high, then
The ambient temperature and each battery temperature are compared (S1).

To prevent each battery from becoming unnecessarily hot,

Are used, the values need not be the respective battery temperatures, and are compared using a representative value such as an average value of the respective battery temperatures. May be performed. Further, the fan control performed in S14 is a fan control for normal battery cooling.
Therefore, the air volume of the cooling fan is an air volume that can sufficiently cool the battery, and can be appropriately determined.

く、適宜決めてよい。Next, in order to perform control for preventing temperature variations among the battery temperatures, it is first determined whether there is a variation between the battery temperatures (S20). If there is a variation, a necessary minimum fan control is performed to eliminate the temperature variation (S22). If there is no variation, the process proceeds to S24. When the battery is abnormal or when the temperature of the battery is high, hydrogen gas may be generated from the battery. Therefore, it is determined in S24 whether there is a possibility that hydrogen gas is generated. If there is a possibility that hydrogen gas is generated, a necessary minimum fan control is performed to prevent the stagnation of hydrogen gas (S22). ). If there is no possibility of hydrogen gas generation, the operation of the fan is stopped (S26). Where S
The minimum necessary fan control of 22 is for preventing battery temperature variations or hydrogen gas stagnation. In the present embodiment, for example, only one of the two cooling fans is operated. Alternatively, any method may be used, such as alternately operating two cooling fans at a low speed. The air flow rate of the cooling fan in S22 may be an amount that prevents the temperature variation of each battery or the retention of hydrogen gas, and may be determined as appropriate.
