Embodiment 1
[0059] figure 1 A schematic flow chart of the cooling method for the battery pack provided by the embodiment of the present invention, as figure 1 As shown, the cooling method of the battery pack in this embodiment may specifically include the following steps:
[0060] 101. Detect the temperature of the battery pack.
[0061] Normally, the battery pack has an optimal temperature range. When the temperature of the battery pack is in the optimal temperature range, the working efficiency is the highest, and it is beneficial to prolong the service life of the battery pack. When the temperature of the battery pack is not in the optimal temperature range , such as in a high temperature environment, the heat generated by the battery pack will dissipate slowly, which will affect the performance of the battery. Therefore, in order to reduce the temperature of the battery pack beyond the optimal temperature range and improve the cooling efficiency, Water cooling will be used to cool d...

[0083] Figure 4 Another schematic flow chart of the battery pack cooling method provided by the embodiment of the present invention, such as Figure 4 As shown, the cooling method of the battery pack in this embodiment may specifically include the following steps:
[0084] 201. Detect the temperature of the battery pack.
[0085] In the embodiment of the present invention, for the specific process of detecting the temperature of the battery pack, refer to the description in step 101 in the above embodiment for details. The principle and implementation process are the same in the embodiment of the present invention, and will not be repeated here.
[0086] 202. Compare the temperature of the battery pack with a preset temperature threshold, and if the temperature of the battery pack is greater than the temperature threshold, determine the target temperature of the coolant according to the temperature of the battery pack.
[0087] In the embodiment of the present invention, th...
