With the development of new energy vehicles, the detection and fault diagnosis of high voltage system of new energy vehicles are becoming more and more important. The leakage of high-voltage system of new energy vehicles will lead to the failure of power on and normal operation of vehicles.
Traditional FDM falls far short of the expected results and cannot meet the requirements. Therefore, the fault diagnosis model based on WOA-LSTM algorithm proposed in the study can improve the safety of the power battery of new energy battery vehicles and reduce the probability of safety accidents during the driving process of new energy vehicles.
The leakage of high-voltage system of new energy vehicles will lead to the failure of power on and normal operation of vehicles. At the same time, it is very important for the safety protection of the whole vehicle.
Composition of high voltage equipment for new energy vehicles 2.1. Power Battery Pack. are connected to the vehicle through high and low voltage plug-ins. The power battery pack provides energy for each system. At the same time, the battery management system extend its service life. 2.2. High Voltage Control Box.
The power battery is one of the important components of New Energy Vehicles (NEVs), which is related to the safe driving of the vehicle (He and Wang 2023). Therefore, accurate diagnosis of power battery faults is an important aspect of battery safety management. At present, FDM still has the problem of inaccurate diagnosis and large errors.
diagnostic instrument. If there is no lea kage, it can be judged that No. 8, No. 9 and No. 10 battery modules may have leakage. However, in actual production modules shall be eliminated, and No. 1-7 battery modules shall be inspected. then switch to the on position, and read the fault with the diagnostic instr ument. have leakage.
