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. Additionally, this SAE Recommended Practice provides five-cycle testing guidelines for vehicles performing supplementary testing on the US06, SC03, and cold FTP procedure. Realistic alternatives should be allowed for new technology.

This SAE Recommended Practice establishes uniform procedures for testing battery electric vehicles (BEV’s) 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 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 is a modification of the urban driving cycles noted in SAE J1082 and which is run on a suitable road or test track. The procedure yields cold start/warm-up fuel economy values indicative of consumer level at the ambient condition of the test. Within referenced limitations, the procedure can be utilized to determine the fuel economy differential among vehicles or between vehicle changes.

This SAE Standard incorporates driving cycles that produce fuel consumption data relating to Urban, Suburban, and Interstate driving patterns and is intended to be used to determine the relative fuel economy among vehicles and driving patterns under warmed-up conditions on test tracks, suitable roads, or chassis dynamometers.1 The urban driving cycle forms the basis of a Cold-Start Test Procedure described in SAE J1256.
