This SAE Recommended Practice establishes uniform procedures for testing Battery Electric Vehicles (BEVs) which are capable of being operated on public and private roads. The procedure applies only to vehicles using batteries as their sole source of power. It is the intent of this document to provide standard tests which will allow for the determination of energy consumption and range for light-duty vehicles (LDVs) based on the Federal Emission Test Procedure (FTP) using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS), and provide a flexible testing methodology that is capable of accommodating additional test cycles as needed. Realistic alternatives should be allowed for new technology. Evaluations are based on the total vehicle system's performance and not on subsystems apart from the vehicle. NOTE: The range and energy consumption values specified in this document are the raw, test-derived values.

This SAE Recommended Practice establishes uniform procedures for evaluating conformity between the actual and target drive speeds for chassis dynamometer testing utilizing standard fuel economy and emissions drive schedules.

This SAE Recommended Practice establishes uniform procedures for testing electric battery-powered vehicles which are capable of being operated on public and private roads. It is the intent of this document to provide standard tests which will allow various performance characteristics of electric vehicles to be cross-compared on a common basis in specifications, technical papers, and engineering discussions. The tests concern attributes of the total vehicle system rather than those of its subsystems and components. Tests of components such as batteries are the subject of separate procedures. The road tests specified in this document are recommended for use whenever possible particularly to establish vehicle performance specifications. The dynamometer procedures are included primarily to facilitate development testing. Paragraph 2.2 provides definitions of terminology used in this document.

This SAE Recommended Practice establishes uniform procedures for testing electric battery-powered vehicles which are capable of being operated on public and private roads, and is to replace the range and vehicle energy economy sections SAE J227a. The procedure addresses electric vehicles (EVs) only. It is the intent of this practice to provide standard tests which will allow for determination of energy consumption and range based on the Federal Emission Test Procedure (FTP) and the Highway Fuel Economy Test Procedure (HWFET). Realistic alternatives should be allowed for new technology. Performance is judged on the total vehicle system and the battery. Dynamometer test procedures are specified in this document in order to minimize the test-to-test variations inherent with track testing and to adhere to standard industry practice for energy consumption and range testing. Section 2 provides definitions of terminology used in this document.

This procedure covers measurement of vehicle road load on a straight, level road at speeds less than 70 mph (113 km/h).

This SAE Recommended Practice establishes a procedure for determination of vehicle road load force for speeds between 115 and 15 km/h (71.5 and 9.3 mph). It employs the coastdown method and applies to vehicles designed for on-road operation. The final result is a model of road load force (as a function of speed) during operation on a dry, level road under reference conditions of 20 °C (68 °F), 98.21 kPa (29.00 in-Hg), no wind, no precipitation, and the transmission in neutral.

This SAE Recommended Practice establishes uniform chassis dynamometer test procedures for hybrid-electric vehicles (HEVs) that are designed to be driven on public roads. The procedure provides instructions for measuring and calculating the exhaust emissions and fuel economy of HEV's driven on the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS), as well as the exhaust emissions of HEVs driven on the US06 Driving Schedule (US06) and the SC03 Driving Schedule (SC03). However, the procedures are structured so that other driving schedules may be substituted, provided that the corresponding preparatory procedures, test lengths, and weighting factors are modified accordingly. Furthermore, this document does not specify which emissions constituents to measure (e.g., HC, CO, NOx, CO2); instead, that decision will depend on the objectives of the tester.
