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...

Abstract

The embodiment of the invention provides a battery pack cooling method and system. The battery pack cooling method provided by the embodiment of the invention comprises the following steps: detecting the temperature of a battery pack, comparing the temperature of the battery pack with a preset temperature threshold, if the temperature of the battery pack is greater than the temperature threshold, determining a target temperature of cooling liquid according to the temperature of the battery pack, and cooling the battery pack by the cooling liquid with temperature less than or equal to the target temperature. By adopting the battery pack cooling method provided by the embodiment of the invention, the target temperature of the cooling liquid necessary for cooling the battery pack is determined by the temperature of the battery pack, thereby improving the cooling flexibility of the battery pack, reducing the electric energy consumption in the battery pack, improving the electric energy distribution rationality of the battery pack and effectively prolonging the service life of the battery pack.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a cooling method and system for a battery pack. Background technique [0002] At present, with the rapid development of the new energy industry, the battery application field is more extensive, such as used in automobiles, by using the power battery system to provide electric energy for electric vehicles, making electric energy the power source of electric vehicles and reducing the use of non-renewable resources. [0003] Generally, the battery will generate a certain amount of heat when it is in the discharge state. When the heat is too high and the battery temperature exceeds the normal temperature range value, the performance of the battery will decrease and the cycle life of the battery will be reduced. In this way, it is necessary to cool down the battery system to make it reach an optimal state. [0004] In the prior art, when water cooling is used to cool the battery, t...
