| Abstract: | In order to solve the problem of inaccurate real-time measurement of input voltage and input current in existing electric vehicle charging piles,a method based on STM32 charging pile voltage and current sampling circuit combined with digital filtering for real-time measurement was proposed,and its feasibility was verified by experiments.The experimental results show that the method can effectively solve the problem of inaccurate voltage and current measurement of AC charging pile under random disturbance in the process of real-time data acquisition of input voltage and current. |
