This SAE Definition Document contains historic voltage regulation methods and test requirements that have not been previously published. The purpose of this document is to recommend a set of definitions and practices for use on current and future 12 V vehicle electric power regulation and control systems in internal combustion engine road vehicles. This document is not intended to include nor exclude regulators used in higher voltage vehicle electrical systems. The term “generator” rather than “alternator” will be used even though these terms may be used interchangeably in practice.

This SAE Information Report is a summary of the initial recommendations of the SAE committee on Dual/Higher Voltage Vehicle Electrical Systems regarding the application of higher voltages in vehicle systems. This document does not attempt to address the technical merits of specific voltages or electrical system architectures.

This SAE Standard specifies test methods and general requirements for the determination of the electrical characteristic data of alternators for road vehicles. It applies to alternators, cooled according to manufacturer’s instructions, mounted on internal combustion engines. This document attempts to follow ISO 8854, dated 1988. ISO 8854 has been modified herein to reflect local market requirements and historical precedent.

This SAE Recommended Practice recommends a common naming convention to be used to designate the terminals on automotive generators found in internal combustion engine road vehicles. The intent is to standardize the terminology in use. This document is not intended to include hybrid and/or electric vehicles.

This SAE Standard contains the industry standard definitions for electrical equipment used in the generation of electric power onboard today's conventional road vehicles. It is intended to complement the electronic terminology that was formerly documented in SAE J1213 (canceled) and/or in other industry glossaries of electrical/electronic devices.
