Moreover, this method can achieve voltage fault diagnosis in advance when the voltage of the faulty cell still within the normal range.
Why do EV batteries fail?
Various faults may occur at each cell or the associated accessories in battery pack due to the natural aging and various (including mechanical, electrical, and thermal) abuse manoeuvres in actual usage of EVs [5 - 7]. Unchecked faults would have great impacts on battery, or even lead to battery thermal runaway under extreme conditions .
Can abnormal battery voltage be used to detect faults in advance?
Therefore, the detection of abnormal changes in battery voltage can be used to detect faults in advance. However, the battery voltage presents nonlinear and time-varying characteristics, so the analysis of the abnormally sharp challenges hidden under the voltage can be challenging.
What are the problems faced by battery fault analysis?
In summary, in practice, the problems faced by battery fault analysis are mainly online use, sensitive characteristics and accurate detection. To overcome the problem of feature sensitivity, a fault diagnosis method based on a wavelet time-frequency diagram and image feature extraction is proposed in this paper.
Why are some batteries misdiagnosed as faulty cells?
Therefore, some normal cells are often misdiagnosed as faulty cells when statistical methods are forced to be used for fault detection, making it difficult to guarantee accuracy [ 19 ]. The measurement signals of faulty cells in the battery pack usually have outlier characteristics.
Is temperature a direct response to battery failure?
