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.
The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
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.
To start the charging pile, click the screen to select the charging mode, choose the charging connector, and begin charging. To stop the charging pile, enter the 'setting interface' -- function setting -- startup mode, and select 'start by button'.
In this paper, the battery energy storage technology is applied to the traditional EV (electric vehicle) charging piles to build a new EV charging pile with integrated charging, discharging, and storage; Multisim software is used to build an EV charging model in order to simulate the charge control guidance module.
In case of a fault, the charging pile will display the related fault code on the charging fault record page, the fault light will be on, and the output of the charging pile will be cut off. Faults in charging piles can be reset by swiping the card. After the settlement is completed, faults will be warned and reset, and the charging pile will enter the standby state.
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.
