Do new energy electric vehicles need a DC charging pile?
New energy electric vehicles will become a rational choice to achieve clean energy alternatives in the transportation field, and the advantages of new energy electric vehicles rely on high energy storage density batteries and efficient and fast charging technology. This paper introduces a DC charging pile for new energy electric vehicles.
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.
The power of mobile charging piles that we have developed is 7 kW so far. And there is energy loss when using mobile charging. The electricity cost of mobile charging pile for consumers is set as 1.5 yuan/kWh, and users should pay an additional 35-yuan service fee for pile delivery each time. The charging stations in the market vary a lot in size.
