本SAE推荐实践建立了测试燃料电池和混合燃料电池电动汽车的统一程序，不包括主要设计用于在公共街道、道路和高速公路上运行的低速车辆。该程序针对使用由非车载源供应的压缩氢气或作为车载压缩气体储存和供应的压缩氢气的测试车辆。 本规范提供了标准测试，允许根据美国联邦排放测试程序，使用城市测功机驾驶时间表（UDDS）和高速公路燃油经济性驾驶时间表（HFEDS）确定油耗和续航里程。 本文件规定了底盘测功机测试程序，以消除赛道测试固有的测试间差异，并遵守油耗和里程测试的标准行业惯例。在开始纳入该实践的官方制造商内部和官方政府确认测试时，车辆制造商和管理机构之间的沟通至关重要。

This SAE Recommended Practice establishes uniform procedures for testing fuel cell and hybrid fuel cell electric vehicles, excluding low speed vehicles, designed primarily for operation on the public streets, roads and highways. The procedure addresses those vehicles under test using compressed hydrogen gas supplied by an off-board source or stored and supplied as a compressed gas onboard. This practice provides standard tests that will allow for determination of fuel consumption and range based on the US Federal Emission Test Procedures, using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS). Chassis dynamometer test procedures are specified in this document to eliminate the test-to-test variations inherent with track testing, and to adhere to standard industry practice for fuel consumption and range testing. Communication between vehicle manufacturer and the governing authority is essential when starting official manufacturer in-house and official government confirmatory testing that incorporates this practice.
