摘　　要：为准确获得某款电动汽车车载高压可充电储能系统(REESS)和B级电力系统负载的绝缘电阻,本文分别采用无源接地式和电压注入式两种方法进行测量,并对测量结果进行误差分析。结果表明,被测车辆的绝缘电阻满足GB/T 18384.3-2015的要求,但其测量精度有待提高。To accurately obtain the insulation resistance values of on-board high-voltage REESS and class B electric power system load for an electric vehicle, the authors respectively apply two methods of no-source ground type and voltage injection type to measure, and analyze the relative errors of the measured data. The results show that the insulation resistance values of the measured vehicle could meet the requirements of GB/T 18384.3-2015, but the measurement accuracy needs to be improved.
