Scope
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. Additional corrections are typically applied to these quantities when used for regulatory purposes (Corporate Average Fuel Economy, vehicle labeling, etc.).
Rationale
Battery Electric Vehicle (BEV) technology has progressed significantly since the original publication of SAE standard J1634. BEV ranges and capabilities made previous test methods of full depletes using repeat UDDS and HFEDS cycles impractical. To reduce lab test burden a Multi-Cycle Test (MCT) was introduced. In addition, specific 5-cycle test procedures have been added to provide clear guidance on one such method of obtaining BEV energy consumption and range in non-ambient conditions.
To provide clearer guidance on BEV 5-cycle testing Appendix B has been added. Appendix B provides one example of how to perform 5-cycle testing and calculate energy consumption and range for BEVs.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
