Maintenance fault light appears on the energy storage charging pile

Why do smart charging piles need maintenance?

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.

What causes a charging pile to fail?

The failure of the charging pile may be caused by many factors, the most common of which is the external environment and operation and maintenance frequency. Therefore, this paper constructs a potential fault identification model of electric vehicle charging pile from the above two aspects.

What happens during the service life of 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). However, before the defects are formed, the failure rate will also gradually increase with the process of cumulative damage.

Can cost-sensitive logistic regression predict smart charging pile faults?

In this article, a real-time fault prediction method combining cost-sensitive logistic regression (CS-LR) and cost-sensitive support vector machine classification (CS-SVM) is proposed. CS-LR is first used to classify the fault data of smart charging piles, then the CS-SVM is adopted to predict the faults based on the classified data.

What are the risk consequences of preventive maintenance of electric vehicle charging pile?

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.

How is a charging pile classified?

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.
