Abstract

The invention belongs to the technical field of thermal management, and discloses a thermal management method, device and equipment of a power battery and a storage medium. The method comprises the following steps: acquiring modeling parameters and target temperature parameters of the power battery; determining a flow distribution proportion according to the modeling parameters; determining a first adjustment strategy according to the modeling parameters and the flow distribution proportion; determining a second adjustment strategy according to the target temperature parameter and the modeling parameter; and performing thermal management on the power battery according to the first adjustment strategy and the second adjustment strategy. Through the mode, the structure of the power battery is adjusted based on the first adjustment strategy and the second adjustment strategy, accurate thermal management on the power battery can be realized, meanwhile, high efficiency of thermal management, temperature homogenization of the power battery and consistency of battery performance are ensured, safety guarantee is provided for subsequent driving safety, and the service life of the power battery is prolonged. And the experience feeling of the user is improved.

Description

technical field [0001] The present invention relates to the technical field of thermal management, and in particular, to a thermal management method, device, device and storage medium of a power battery. Background technique [0002] With the increase in the sales of electric vehicles, the thermal safety of power batteries has attracted increasing attention. Excessive battery temperature will affect the performance of the battery, and in severe cases, it will lead to thermal runaway, which will affect the driving safety of electric vehicles. Therefore, the safety of the power battery is the most important part of electric vehicle management. Under normal circumstances, it is necessary to ensure the uniformity of the temperature of the power battery and the consistency of the battery performance. The efficiency of processing and research is still relatively low. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a thermal management m...
