Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0036] Such as figure 1 As shown, a charging station operating state risk assessment method includes the following steps:

[0037] Step 1, define several first-level risk assessment indicators of the charging station, and each first-level risk assessment indicator contains several second-level risk assessment indicators.

[0038] The first-level risk assessment index set is U={U 1 ,...,U i ,...,U n}, U i is the i-th primary risk assessment indicator, 1≤i≤n, n is the total number of defined primary risk assessment indicators, U i ={u i1 ,...,u ij ,...,u im},u ij is the j-th secondary risk assessment indicator in the i-th primary risk assessment indicator, 1≤j≤m, and m is the total numbe...

Abstract

The invention discloses a risk assessment method for a running state of a charging station. The method comprises the steps of defining a plurality of primary risk assessment indexes of the charging station, wherein each primary risk assessment index comprises a plurality of secondary risk assessment indexes; performing single-level fuzzy analysis on the primary risk assessment index by applying a fuzzy analytical hierarchy process; performing multi-level fuzzy comprehensive assessment on the secondary risk assessment indexes by applying the fuzzy analytical hierarchy process; and according to a multi-level fuzzy comprehensive assessment result, calculating a risk assessment value. According to the method, the fuzziness and levelness among risk assessment factors of a charging and battery replacement station are considered, and the performance of each factor in assessment is clearly determined through an expert experience marking table, so that the risk assessment is more objective, safe running of the electric vehicle charging and battery replacement station is realized, and the hazard loss is reduced to minimum.

Description

technical field [0001] The invention relates to a risk assessment method for the operating state of a charging station, and belongs to the technical field of electric vehicle charging safety. Background technique [0002] As one of the main development directions of new energy vehicles, electric vehicles are getting more and more attention. With the large-scale development of electric vehicles and the increase in the number of battery charging stations and charging and swapping stations, higher requirements are placed on their operational reliability. Risk assessment is a qualitative or quantitative analysis of many evaluation factors in the charging and swapping station, and then comprehensively analyzes the risk occurrence degree of each factor. It is an important part of the safety decision-making in the operation and maintenance process of the charging and swapping station. Through the risk assessment of the charging and swapping station, determine the factors with a hi...
