Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] The solution of the embodiment of the present invention is mainly: the present invention acquires the current working state, current parameter and voltage parameter of the battery pack to be detected; It can improve the accuracy of differential pressure fault judgment. By combining the current working status, current parameters and voltage parameter factors, the comprehensive judgment can increase the accuracy and stability of differential pressure fault judgment. Due to the dynamic changes of current and voltage It can determine the differential pressure fault state of the battery pack to be detected in real time, which improves the efficiency of differential voltage fault judgment of the battery, and solves the problem that the battery differential pressure fault judgment method in the prior art is relatively ...

Abstract

The invention discloses a battery pack drop-out fault judgment method and device and a storage medium. The method comprises the steps of obtaining a current working state, a current parameter and a voltage parameter of a to-be-detected battery pack; and judging a drop-out fault of the to-be-detected battery pack according to the current working state, the current parameter and the voltage parameter. The drop-out fault judgment accuracy can be improved, the accuracy and stability of drop-out fault judgment can be improved by combining the comprehensive judgment of the current working state, thecurrent parameter and the voltage parameter, the drop-out fault state of the to-be-detected battery pack can be determined in real time due to the dynamic change of current and voltage, and the drop-out fault judgment efficiency of the battery is improved.

Description

technical field [0001] The present invention relates to the technical field of battery management, in particular to a battery pack pressure difference fault judgment method, equipment and storage medium. Background technique [0002] At present, pure electric vehicles on the market diagnose the voltage difference between the cells of the battery pack. Different usage conditions, considering the two influencing factors of temperature and SOC, and obtaining the differential pressure fault values ​​at different temperatures will all affect the judgment of differential pressure faults. Contents of the invention [0003] The main purpose of the present invention is to provide a battery pack differential pressure fault judgment method, equipment and storage medium, aiming to solve the problem that the battery differential pressure fault judgment method in the prior art is relatively single, and the influence of environmental factors on the differential pressure fault judgment is...
