Research on Intelligent Diagnosis Strategy and Treatment Method of ev Charging Fault

With electric cars, large-scale development, in order to reduce the potential safety hazard in the process of electric vehicle charging, in this paper, by analyzing the power battery, charging pile, power supply equipment integration between safety mechanism, puts forward the integration of fault logic judgment business process, established a multistage equipment integration on-line fault diagnosis of the fault tree, making the integration of fault judging module and fault processing module, information mining and integrated warning index pretreatment technology is studied, which can effectively improve the electric car charging security, promote the healthy development of electric vehicles.
