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 DC charging pile and its control technology provide some technical guarantee for the application of new energy electric vehicles. In the future, the DC charging piles with higher power level, high frequency, high efficiency, and high redundancy features will be studied.
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.
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.
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
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.
