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 feasibility of the DC charging pile and the effectiveness of the control strategies of each component of the charging unit are verified by simulation and experimental results. This DC charging pile and its control technology provide some technical guarantee for the application of new energy electric vehicles.
The advantage of DC charging pile is that the charging voltage and current can be adjusted in real time, and the charging time can be significantly shortened when the charging current are large, which is a more widely used charging method at present.
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 [11, 12, 13], when DC charging piles use non-isolated DC/DC converters, the batteries are not electrically isolated from the grid, which has certain safety hazards.
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
