Combined with the fault parameters, the consequence of the charging pile failure event to the user is quantified as system risk. The risk tracking of the charging station is carried out, and the risk level of each station is evaluated with the maintenance sequence determined.
The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
Since the smart charging piles are generally deployed in complex environments and prone to failure, it is significant to perform efficient fault diagnosis and timely maintenance for them.
Considering the actual situation of the operation of the electric vehicle charging pile, that is, with the increase of the operation time of the electric vehicle charging pile, the failure rate is higher and higher, and the maintenance frequency is higher and higher.
Comparison of risk consequences of three models. The risk consequence of preventive maintenance decision of electric vehicle charging pile is actually the load loss value.
Combined with the fault degree, maintenance experience, and expert analysis of the charging pile, the state classification strategy is given. Each indicator of the charging pile is standardized according to the threshold level of the operating state.
During the service life of the electric vehicle charging pile, the cumulative factor of service life will gradually develop toward the state inducement factor (deterioration causes defects). However, before the defects are formed, the failure rate will also gradually increase with the process of cumulative damage.
Combined with the fault parameters, the consequence of the charging pile failure event to the user is quantified as system risk. The risk tracking of the charging station is carried out, and the risk level of each station is evaluated with the maintenance sequence determined.
