摘要
针对当前新能源汽车驱动电机能效测评方法复杂、成本高的问题，本研究提出一种简化的测评指标框架。基于《中国汽车能效分级测试评价规程 第 1 部分：纯电动乘用车》，通过优化转速 - 转矩测试点选取规则，将测试点数量减少约30%，并引入线性插值算法补全效率数据。以一款纯电动乘用车电机为案例进行验证，简化方法计算的高效区占比与原标准方法结果的偏差小于 5%，同时测试效率提升约 40%。该方法为电机能效的快速评估与产品优化提供了有效工具，契合行业发展需求。
Abstract
Aiming at the problems of complexity and high cost in the current energy efficiency evaluation methods for new energy vehicle drive motors, this study proposes a simplified evaluation framework. Based on "China Automotive Energy Efficiency Classification Test and Evaluation Procedure Part 1: Battery Electric Passenger Cars", the number of test points is reduced by about 30% by optimizing the selection rules of speed-torque points, and a linear interpolation algorithm is introduced to supplement efficiency data. A case study on a battery electric passenger car motor shows that the deviation of the high-efficiency area ratio calculated by the simplified method from the standard method is less than 5%, while the testing efficiency is improved by about 40%. This method provides an effective tool for rapid motor energy efficiency assessment and product optimization, which is in line with industry development needs.
