Quantitative assessment of electric safety protection for electric vehicle charging equipment

By the rapid development of EV industry, electric safety accidents occurred sometimes, charging equipment and power battery are two main aspects. At present, the assessment of electrical safety is still in the level to meet the relevant standards and lack of complete assessment method. In this paper, according to the electric safety protection of electric vehicle charging equipment, a new method based on synthetic weight is proposed. This method quantifies the abstract ability of electrical safety and a real charging equipment is tested in order to verify the validity of the evaluation index.
