Problems solved by technology

[0005] However, due to the differences in structure, material and process of different power batteries, there are also differences in the characteristics of parameters such as temperature and voltage during operation. Therefore, due to these uncertain factors, the fault determined by the BMS may be a false alarm. As a result, the VMS performs wrong fault handling, affecting the normal driving of the vehicle

Abstract

The invention discloses a method for preventing battery failure false alarm and an apparatus thereof. The method comprises the following steps: determining whether a battery is fault or not by monitoring performance parameter of the power battery; when the power battery is fault, whether secondary diagnosis condition is satisfied or not can be determined; when the secondary diagnosis condition is satisfied, a fault power battery monomer is determined in the power battery; a battery module group of the fault power battery monomer is determined; according to the abnormal performance parameter of the fault power battery monomer and the performance parameter of the other power battery monomer in the battery module group of the fault power battery monomer, whether the power battery fault is the false alarm or not can be determined; when the power battery fault is determined as false alarm, false alarm is removed, and the false alarm of the power battery fault is avoided.

Description

technical field [0001] The invention relates to the technical field of automotive power battery management, in particular to a method and device for preventing false alarms of battery failures. Background technique [0002] As a new type of clean energy vehicle, electric vehicles have the characteristics of low noise, no pollution, zero emissions, and high energy conversion efficiency. It is a new trend in future automotive development. With the development of electric drive technology, the technology of pure electric vehicles has become increasingly mature, and has been widely promoted and applied. [0003] The power battery is the core component that provides power for electric vehicles, and the safety and cost of power batteries are the main factors affecting the application of electric vehicles. Therefore, the vehicle's control of power batteries, motors and various system components is an important development direction of electric vehicles. [0004] At present, the m...
