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.

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.

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 is a DC charging pile?

DC charging piles are commonly found in public charging stations, where EV owners can quickly recharge their vehicles while on the go. Why is DC charging bad for EVs? While DC charging offers faster charging times, it comes with a few considerations that can be considered disadvantages for certain EVs: 1.

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.

What's wrong with public EV charging?

The short answer is data. Hundreds of things can go wrong in the EV charging process, but the data to figure out why is unavailable. New government rules aim to solve that. This is the second piece in a three-part series exploring the biggest problems with public EV charging — and how to fix them (read Part 1).
