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.
Each indicator of the charging pile is standardized according to the threshold level of the operating state. According to the advantages and disadvantages of the operating parameters, it can be divided into four risk levels: health, normal, minor failure, and serious failure.
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.”
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.
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.
The traditional charging pile management system usually only focuses on the basic charging function, which has problems such as single system function, poor user experience, and inconvenient management.
