When the temperature of the battery pack is higher than a target temperature range, the heat dissipation effect of the fan rotating speed or the compressor power corresponding to the water temperature is insufficient, the heat dissipation requirement of the battery pack can be met by adjusting the fan rotating speed interval/the compressor sub-power interval corresponding to the water temperature, when the temperature of the battery pack is lower than the target temperature range, the heat dissipation effect of the fan rotating speed or the compressor power corresponding to the water temperature is too low, the fan/the compressor can be temporarily turned off, so that energy waste is reduced, and when the temperature of the battery pack is in the target temperature range, the fan/the compressor is turned on again to dissipate heat.

And adjusting the fan rotating speed and/or the compressor power corresponding to the water outlet temperature according to the battery pack temperature in the unit time period, so that the adjusted fan rotating speed and/or the compressor power can meet the heat dissipation requirement of the battery pack, updating the preset first corresponding relation and/or the preset second corresponding relation is finished, the updated preset first corresponding relation and/or the updated preset second corresponding relation is applied to the next unit time period, and the heat dissipation of circulating water flowing through the battery pack by the fan and/or the compressor in the next unit time period can be more accurate.
