摘　　要：为解决现有电动汽车充电桩中输入电压与输入电流实时测量不准确问题,提出了一种基于STM32的充电桩电压电流采样电路结合数字滤波进行实时测量的方法,并通过实验验证其可行性。实验结果表明,该方法在交流充电桩输入电压与电流实时采集数据过程中,可以有效地解决在随机扰动情况下交流充电桩电压电流测量不准确的问题。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.
