What is a DC charging pile for new energy electric vehicles?
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.
What is a DC charging pile?
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.
How many charging units are in a new energy electric vehicle charging pile?
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.
Do DC charging piles use a non-isolated DC/DC converter?
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.
What is the topology of a DC charging pile?
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
What happens if a DC charging pile is uncontrollable?
In [5, 6], the rectifier of the DC charging pile is an uncontrollable rectifier. When the uncontrollable rectifier works, it will inject large harmonic current into the AC grid, the harmonic current will affect the service life of the input transformer, increase the power grid loss, and cause voltage fluctuation.
