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 paper introduces a high power, high eficiency, wide voltage output, and high power factor DC charging pile for new energy electric vehicles, which can be connected in parallel with multiple modular charging units to extend the charging power and thus increase the charging speed.
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.
In order to achieve high power and fast charging function, multiple charging units are operated in parallel. When one or more of the charging units have problems, these problematic charging units can be stopped and the other charging units continue to operate normally.
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. 12a.
