当前的汽车电磁排放测量实践是针对装备有传统内燃机的车辆开发的。然而，基于电力和动力电池电源的替代动力系统技术在常规（静态）排放测试条件下不起作用。因此，一个程序的测量进行了一个小的一组代表性的替代动力系统的道路车辆，以量化其排放量，并调查相关的实际测量问题。这项工作还包括在9 kHz至30 MHz的频率下对发射进行调查。它的结论是，需要动态测试条件，以允许更现实的评估水平所产生的电动动力总成部件的排放。
Current automotive electromagnetic emissions measurements practices were developed for vehicles equipped with conventional internal combustion engines. However, alternative powertrain technologies based on electric and power cell power sources are not active under conventional (static) emissions test conditions. A program of measurements has therefore been conducted on a small set of representative alternative powertrain road vehicles in order to quantify their emissions and to investigate the associated practical measurement issues. This work also included investigation of emissions at frequencies from 9 kHz to 30 MHz. It is concluded that dynamic test conditions are needed to permit a more realistic assessment of the level of emissions generated by electric powertrain components.
