Abstract

The embodiment of the invention provides a battery equalization function test method and device, equipment and a storage medium. The method comprises the steps of obtaining the real data of equalization parameters of a battery when the equalization of the battery is started; determining a corresponding working scene based on the real data of the equalization parameters; determining change characteristics of each equalization parameter and correlation characteristics among the equalization parameters based on the real data of the equalization parameters; based on the equalization parameters, the change characteristics of the equalization parameters and the correlation characteristics among the equalization parameters, establishing equalization simulation working conditions; simulating the equalization simulation working conditions in the working scene; and determining an equalization effect based on the data of the equalization parameters output after the equalization simulation working condition simulation is finished. According to the technical scheme provided by the embodiment of the invention, relevant parameters of equalization starting can be simulated, so that the equalization function and the equalization effect are verified, and the problems of long test period and relatively single working condition are solved.

Description

technical field [0001] The embodiments of the present invention relate to a balancing function testing technology, in particular to a battery balancing function testing method, device, equipment and storage medium. Background technique [0002] The inconsistency of the battery in the car will have a negative impact on the life of the battery and the use of the battery management system. Therefore, during the use of the battery, it is necessary to perform active or passive equalization to prolong the battery life. In order to ensure the production quality of the battery, it is necessary to test the equalization function of the battery. [0003] The test of the battery equalization function in the related art is to verify the entry and exit conditions of the equalization on the hardware-in-the-loop (HIL) test equipment, and to verify the equalization effect in the bench and real vehicle tests. The test cycle is long and the working conditions are single. Contents of the inv...
