Research on Comprehensive Evaluation of Electric Vehicle Charging Failures

With the large-scale development of electric vehicles, in order to reduce the potential safety hazards in the charging process of electric vehicles, this paper analyzes the charging safety characteristics of electric batteries, charge and discharge equipment, and power supply equipment of electric vehicles, studies the fault correlation between multi-level equipment, and establishes an integrated fault priority comprehensive evaluation model based on comprehensive fuzzy analytic hierarchy process. The data on the interconnected data platform can be used to obtain a quantitative evaluation result of the actual demonstration effect, and the actual effect of the integrated security early warning system. It can effectively improve the charging safety of electric vehicles and promote the healthy development of electric vehicles.
