TrendForce''s latest findings report that global public EV charging pile deployment is being constrained by land availability and grid planning, compounded by a slowdown in the growth of the NEV market. The 2024 growth rate is a projected 30%—a sharp drop from the 60% recorded in 2023.
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 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.
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.
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 [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.
In , the rectifier of DC charging pile is three-phase two-level PWM rectifier, and the three-phase two-level PWM rectifier must be connected to an LC or LCL filter for filtering, otherwise the rectifier will inject a large harmonic current into the grid.
