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. One of the key problems to be solved is how to conduct fault prediction based on limited data collected through IoT in the early stage and develop reasonable ...
The importance of maintaining charging piles lies in the fact that influences by the changeable environment and ageing inner parts can cause various faults. Regular examination and maintenance are necessary during both product storage and using processes.
Indoor charging piles should have a protection level of at least IP32 or above, while outdoor charging piles need to have a protection level of at least IP54 to ensure the safety of human bodies and charging equipment in harsh environments with wind, rain, and the need for better insulation and lightning protection.

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.
