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.
According to the average power change of the new public DC charging piles over the years (Fig. 5.6), the high-power charging piles with 120 kW and above are proliferating, and the charging piles are gradually developing towards high power.

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.
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.
Regarding charging methods, new energy private cars mainly rely on slow charging, supplemented by fast charging; other operating vehicles mainly rely on fast charging, supplemented by slow charging.
Zhang Han et al. see the health evaluation, bad working condition evaluation and aging maintenance evaluation as the basic elements of the health state evaluation of a charging pile and predict the health state of a charging pile based on a Markov prediction model.
