Figure 7 shows the waveforms of a DC converter composed of one circuit. The reference current of each circuit is 25A, so the total charging current is 100A. Ib1, Ib2, Ib3 and Ib4 are the output currents of charging unit 1, unit 2, unit 3 and unit 4, respectively. IB is the charging current of the battery. Io1 is the output.

Simulation waveforms of a new energy electric vehicle charging pile composed of four charging units Figure 8 shows the waveforms of a DC converter composed of three interleaved circuits. The reference current of each circuit is 8.33A, and the reference current of each DC converter is 25A, so the total charging current is 100A.
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.
Charging piles are mainly divided into AC charging piles and DC charging piles. AC charging piles have a smaller body, are flexible for installation, and typically take 6-8 hours to fully charge. They are suitable for small electric vehicles and are commonly used in public parking lots, large shopping centers, and community garages.
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.
In this paper, based on the cloud computing platform, the reasonable design of the electric vehicle charging pile can not only effectively solve various problems in the process of electric vehicle charging, but also enable the electric vehicle users to participate in the power management.
