AI Customer ServiceIn this paper, the fault diagnosis of battery systems in new energy vehicles is reviewed in detail. Firstly, the common failures of lithium-ion batteries are classified, and the triggering mechanism of battery cell failure is briefly analyzed. Next, the existing fault diagnosis methods are described and classified in detail.
Table 2 Statistical table of A phase current in normal state From the above analysis, it can be known that the new energy vehicle fault diagnosis system constructed in this paper has a good diagnosis effect, so it can be applied to subsequent practice.
Currently, the methods used for battery system fault diagnosis mainly include model-based, data-driven, knowledge-based, and statistical analysis-based methods, as shown in Figure 3. Furthermore, Table 1 shows the fault diagnosis methods and typical fault diagnosis cases. Figure 3.
Due to road conditions, technology and other reasons, the storage battery, as a weak link of electric vehicles, is a frequent occurrence point of faults and the focus of fault diagnosis (Wang et al. 2017). The purpose of intelligent fault diagnosis of electric vehicles is to detect faults in the system based on actual detection data.
This paper applies the machine learning algorithm to the fault diagnosis of the new energy electric drive system, simulates the current common system fault conditions, and uses the system constructed in this paper to perform system fault diagnosis. The results are shown in Table 1 and Fig. 9.
Management system fault: In the field of new energy vehicles, the function of power BMS mainly contains two aspects, which are monitoring and management. That is a real-time estimation of battery performance parameters and effective control of battery temperature according to the application environment .
