摘　　要：本文研究了CyberC3无人驾驶电动汽车电源管理系统的电磁干扰现象,分析了产生电磁干扰的原因,运用硬件隔离和软件滤波的方法对原有电源管理系统进行了硬件和软件两方面的抗干扰设计。通过对原有常规采样调理电路和基于HCNR200的线性光耦隔离调理电路的抗干扰对比实验,发现隔离电路的结果明显优于常规电路。表明硬件隔离和软件滤波是非常有效的抗干扰方法。This paper studied electro magnetic interference（EMI） phenomenon in CyberC3 intelligent vehicle power BMS, analyzed the causes, realized hardware and software anti-inter-ference design on the original BMS using hardware isolation and software filter methods. Contrast experiments were carried out on common sampling regulating circuit and linear optocoupler isolation regulating circuit based on HCNR200. The result of isolation circuit is evidently better than that of common circuit. Hardware isolation and software filter are proved to be very effective ways of anti-interference.
