推荐规程描述了一种设计标准，该标准定义了12/24-V起动机系统的起动马达主电路以及控制系统电路的最大推荐电压降。本文件开发中使用的电池技术包括淹没式铅酸、凝胶电池和AGM。本文件中不包括由NiCd、锂离子、NiZn等或Ultracaps支持的启动系统。本文件不打算更新或修改，以包括额定电压高于额定24V电气系统的起动电机。起动机基本上是一个电气-机械功率转换器。如果将可用电池电量增加一倍，则将峰值机械功率增加一倍并使热损失增加一倍。 这意味着，当我们改变电池电压时，我们必须特别注意电池功率的变化，以及它可能对启动系统产生的影响。需要制定一份新的独立文件，以解决额定值高于额定24V系统的启动电机系统的电路性能问题。

The recommended practice describes a design standard that defines the maximum recommended voltage drop of the starting motor main circuits, as well as control system circuits, for 12/24-V starter systems.The battery technologies used in developing this document include the flooded lead acid, gel cell, and AGM. Starting systems supported by NiCd, Lithium Ion, NiZn, etc., or Ultracaps are not included in this document.This document is not intended to be updated or modified to include starter motors rated at voltages above the nominal 24-V electrical system. The starter is basically an electrical-to-mechanical power converter. If you double the available battery power in, you double the peak mechanical power out and double the heat losses. This means that we have to pay special attention to how battery power changes when we change the battery voltage and the effects it may have in overpowering the cranking system. A new stand-alone document would need to be developed to address electrical circuit performance for starter motor systems with ratings above the nominal 24-V system.
