Abstract

The invention belongs to the technical field of automobiles, and discloses a battery pack voltage disorder fault judgment method, device and equipment and a storage medium. The method includes: acquiring parameter information of a vehicle battery pack, and judging whether the vehicle battery pack meets a differential pressure fault condition according to the parameter information; when the vehicle battery pack meets the voltage difference fault condition, determining the voltage disorder level of the vehicle battery pack according to the parameter information; when the voltage disorder grade is the preset grade, judging that the vehicle battery pack has a preliminary voltage disorder fault; when the vehicle battery pack has the initial voltage disorder fault, standing the vehicle battery pack and acquiring second parameter information of the vehicle battery pack; and judging whether the vehicle battery pack has a voltage disorder fault or not according to the second parameter information. Compared with an existing mode that the voltage difference fault phenomenon is judged to be the voltage difference fault, the mode can accurately judge whether the voltage is temporarily disordered or the voltage difference fault actually occurs in the battery pack or not, and the situation that use of a user is affected, and the maintenance cost is increased is avoided.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a battery pack voltage disorder fault judgment method, device, equipment and storage medium. Background technique [0002] The reasons for the uneven temperature distribution of the battery pack are as follows: when the battery pack is used in the whole vehicle, due to the uneven current distribution; the battery pack is naturally cooled, air-cooled, and has no liquid cooling system; Continuously, the battery pack has no rest time, increasing the uneven temperature distribution. Uneven temperature will cause large errors in the acquisition of the voltage in the battery pack, and even temporary voltage disturbances. Voltage disorder means that the voltage of several strings or multiple strings of modules in the battery pack is too low or too high. [0003] Voltage disturbance occurs, that is, there may be a large static or dynamic pressure difference. If the phenomenon of v...
