本SAE推荐实施规程包括测功机测试程序，该程序可在地面街道上走走停停的城市骑行和包括高速公路运行在内的城市地区通勤行程中对电动摩托车的行驶里程进行估计。这通常是使用“滑行”方法完成的，方法是断开发动机并假设所有损失都是空气动力学损失。然而，由于电机存在固有损耗，且无法完全脱离电机，另一种方法是对全电动车辆使用“道路上恒速”（附录B）方法来确定测功机系数。

This SAE Recommended Practice incorporates dynamometer test procedures that produce riding range estimates for electric motorcycles during stop-and-go urban riding on surface streets and commuting trips in urban areas that include operation on freeways. This is typically done using a “coastdown” approach by disengaging the engine and assuming all losses are aerodynamic. However, with inherent losses in an electric motor, and no way to fully disengage the motor, another approach is to use a “on-road, constant speed” (Appendix B) method for fully electric vehicles to develop dynamometer coefficients.
