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.
This paper introduces a DC charging pile for new energy electric vehicles. The DC charging pile can expand the charging power through multiple modular charging units in parallel to improve the charging speed. Each charging unit includes Vienna rectifier, DC transformer, and DC converter.
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.
The main components of the charging pile include: controller, man–machine components, lightning protector, contactor, fuse, socket, charging cable, DC charging vehicle plug, emergency stop button, pile, etc. As shown in Fig. 12 a. Experimental waveforms of DC charging pile with electric vehicle battery load
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.
Topology 1 is the topology of a DC charging pile consisting of three parts: Vienna rectifier, DC transformer, and DC converter. Topology 2 is the topology of a DC charging pile consisting of two parts: Vienna rectifier and DC transformer. Table 10 Working efficiency of a DC charging pile with different topologies
