标准摘要
[中文适用范围]： 本文件提供了通过直接测量驱动轮轮毂或车轴来评估电动汽车动力总成系统最大功率的测试方法。还专门针对插电式混合动力汽车进行了额外的测试，以测量纯电动推进功率，并针对混合动力汽车进行了测量电力辅助和再生制动。测试需要所有驱动轮的底盘或轮毂测功机。对结果进行处理，以提供不同电气化动力系统设计之间动力能力的公平且一致的比较。如果需要与电动车辆进行精确比较，也可以在传统车辆上进行测试。 [外文原描述]： This SAE Information Report provides test methods and determination options for evaluating the maximum wheel power and rated system power of vehicles with electrified vehicle powertrains. The scope of this document encompasses passenger car and light- and medium-duty (GVW <10000 pounds) hybrid-electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), battery electric vehicles (BEVs), and fuel-cell electric vehicles (FCEVs). These testing methods can also be applied to conventional ICE vehicles, especially when measuring and comparing wheel power among a range of vehicle types.This document version includes a definition and determination methodology for a rated system power that is comparable to traditional internal combustion engine power ratings (e.g., SAE J1349 and UN ECE R85). The general public is most accustomed to “engine power” and/or “motor power” as the rating metric for conventional and electrified vehicles, respectively. Wheel power will always be a lower-power result, owing to losses in the drivetrain that take power away from the power-producing components as it flows to the wheel. The methods in this document for determining rated system power were developed recognizing that no single approach is suitable for all powertrains without some variations specific to the powertrain type (e.g., BEV versus HEV) and the limits of test practicality.Additional power-related tests are included to address unique operational capabilities of electrified vehicles.Cross Reference:
