If the growth rate of private charging piles or public charging piles can be maintained, then the ratio of vehicles to piles in an ideal state will be 1:1. It will be realized in 2030, and the charging of new energy vehicles will become easier and easier.
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 research simulation predicts that in the next 10 years, the ratio of vehicles to piles of new energy vehicles in China will become lower and lower. If the growth rate of private charging piles or public charging piles can be maintained, then the ratio of vehicles to piles in an ideal state will be 1:1.
The feasibility of the DC charging pile and the effectiveness of the control strategies of each component of the charging unit are verified by simulation and experimental results. This DC charging pile and its control technology provide some technical guarantee for the application of new energy electric vehicles.
The advantage of DC charging pile is that the charging voltage and current can be adjusted in real time, and the charging time can be significantly shortened when the charging current are large, which is a more widely used charging method at present.
According to the survey statistics of the China Electric Vehicle Charging Infrastructure Promotion Alliance, the construction of private charging piles is mainly affected by factors such as the degree of property cooperation, fixed parking spaces, power connection factors, and dedicated venues (EVCIPA).
