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 eficiency of the DC charging pile with DC transformer structure is lower than that of the DC charging pile without DC transformer structure, but the DC charging pile with DC transformer structure has the function of electrical isolation.
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.
To optimize grid operations, concerning energy storage charging piles connected to the grid, the charging load of energy storage is shifted to nighttime to fill in the valley of the grid's baseline load. During peak electricity consumption periods, priority is given to using stored energy for electric vehicle charging.
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.
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
