What happens if fault is not cleared in charging pile?

If a fault is not cleared in a charging pile, it could not work normally after started a second time. After settlement completion, faults are warned and reset, and the charging pile enters a standby state. Only after the fault has been cleared can the charging pile work by restarting.

Can CS-LR predict smart charging pile faults based on classified data?

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. The feasibility of the proposed model is illustrated through the case study on fault prediction of real-world smart charging piles.

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.

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.

Are smart charging piles an important part of the smart grid?

Abstract: With the application of the Internet of Things (IoT), smart charging piles, which are important facilities for new energy electric vehicles (NEVs), have become an important part of the smart grid.

What does the charging station tell the EV?

Among other things, the charging station informs the EV of the maximum charging current available. At the same time, the EV informs the charging station about its status, for example whether the EV is connected or whether it is currently charging. Why is CP line calibration necessary?
