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.
This study has good application prospects in improving the preventive maintenance effect of electric vehicle charging piles. In recent years, electric vehicles have been gradually developed and widely used in many countries due to their advantages of cleanliness, environmental protection, and efficiency.
The experimental results show that the accuracy of this method in preventive maintenance decision-making for electric vehicle charging piles can reach 98%, with an average preventive maintenance decision-making time of 1.6 s for load piles. At the same time, the risk probability value and load loss value are effectively controlled.
However, the operation parameter data resources of the charging pile are limited, and cannot be further supplemented and improved according to the actual station operation scenario to obtain a more comprehensive and stable state evaluation or prediction.
Charging model of the DC charging pile. On the left is the off board charger (i.e., DC charging station), and on the right is the electric vehicle, which are connected through vehicle plugs and sockets. We can clearly see that the charging model is mainly composed of three parts: “off board charger,” “vehicle interface,” and “electric vehicle.”
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.
