6 FAQs about [New Energy Battery Fault Signage]
Can a fault diagnosis model improve the safety of new energy battery 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.
Why is accurate diagnosis of power battery faults important?
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.
How accurate is a battery safety fault diagnosis model?
In order to monitor the health status and service life of the battery, the team of Samanta designed a battery safety fault diagnosis model based on artificial neural network and support vector machine (Samanta et al. 2021). We compared the model with other models. The results showed that the fault detection accuracy of the model reached 87.6%.
How do you know if a battery has a fault?
When the residual signal detects the fault, if the temperature increases more than the determined threshold, it can be concluded that an internal battery such as short circuit happened. If the temperature is lower than the threshold, it shows that a sensor fault happened.
Does a fault diagnosis scheme consider battery aging effects?
