AI Customer ServiceComparison of risk consequences of three models. The risk consequence of preventive maintenance decision of electric vehicle charging pile is actually the load loss value.
The severity can be characterized by the state evaluation results of the electric vehicle charging pile. 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).
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.
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.
The aging failure of the equipment and components inside charging piles also affects the safety of charging piles in use.
In terms of communication safety, charging piles face various information safety threats, including natural elements and human elements, which show a changing trend over time .
