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.
Design of Energy Storage Charging Pile Equipment The main function of the control device of the energy storage charging pile is to facilitate the user to charge the electric vehicle and to charge the energy storage battery as far as possible when the electricity price is at the valley period.
As one of the new infrastructures, charging piles for new energy vehicles are different from the traditional charging piles. The "new" here means new digital technology which is an organic integration between charging piles and communication, cloud computing, intelligent power grid and IoV technology.
Charging piles are of great significance to developing new energy vehicles, and they are also an important part of the emerging digital economy such as intelligent traffic and intelligent energy. The State Grid Corporation of China (SGCC) is taking an active role in the development of new energy vehicles.
Charging piles are mainly installed in shopping malls, shopping centers, residential parking lots, downstairs units and charging and changing stations, which can provide charging services for electric vehicles of different types and voltage levels. Figure 1. Charging pile for electric vehicles.
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.
