公路电动摩托车行驶里程测试程序

[中文适用范围]： 本 SAE 推荐做法结合了测功机测试程序，该程序可估算电动摩托车在城市街道上走走停停的骑行和在城市地区通勤（包括高速公路）时的行驶里程。这通常使用“滑行”方法完成，即断开发动机并假设所有损失都是空气动力学损失。但是，由于电动机本身存在损失，并且无法完全断开电动机，因此另一种方法是使用“道路上恒速”（附录 B）方法为全电动汽车制定测功机系数。 [外文原描述]： 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.Cross Reference: J1263,J213_201409,J2263_202005
