本SAE定义文件包含以前未发布的历史电压调节方法和试验要求。本文件的目的是推荐一套用于内燃机道路车辆当前和未来12 V车辆电力调节和控制系统的定义和实践。本文件不包括也不排除高压车辆电气系统中使用的调节器。将使用术语“发电机”而不是“交流发电机”，即使这些术语在实践中可以互换使用。本推荐规程旨在减少汽车发电机系统调节方法的全球变化

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 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 recommended practice has been developed to reduce the worldwide variation in regulation methods used on automotive generator systems
