RISK ASSESSMENT METHOD FOR OPERATION STATE OF CHARGING STATION

摘要

A risk assessment method for an operation state of a charging station. The method comprises: defining several first-level risk assessment indexes for a charging station, each of the first-level risk assessment indexes containing several second-level risk assessment indexes; using a fuzzy analytical hierarchy process to perform single-hierarchy fuzzy analysis on the first-level risk assessment indexes; using the fuzzy analytical hierarchy process to perform multi-hierarchy fuzzy comprehensive assessment on the second-level risk assessment indexes; and calculating a risk assessment value according to a result of the multi-hierarchy fuzzy comprehensive assessment. In the assessment method, fuzziness and hierarchy between various factors of risk assessment on charging and battery swap stations are taken into account, and the performance of each factor in the assessment is specified via an expert experience marking table, so that the risk assessment is more objective, and the safe operation of charging and battery swap stations for electric vehicles is achieved, thereby reducing danger and loss to the minimum.
