纯电动汽车能量回收标定方法研究

Research on Energy Recovery Calibration Method of Pure Electric Vehicle

能量回收是提升纯电动汽车续驶里程的关键技术之一,文章基于某纯电动汽车,介绍了并行能量回收系统的组成部件、工作原理和典型特点,对能量回收的标定策略、方法进行分析研究,特别对能量回收扭矩的标定进行了详细阐述,有效保证了车辆的经济性测试结果满足设计指标要求,同时确保了车辆在能量回收时具有良好的主观感受。

Energy recovery is one of the key technologies to improve the driving range of pure electric vehicles,based on a pure electric vehicle,this paper introduces the components,working principle and typical characteristics of the parallel energy recovery system,analyzes and studies the calibration strategy and method of energy recovery,especially the calibra-tion of energy recovery torque.It effectively ensures that the economic test results of the vehicle meet the requirements of design index,and at the same time ensures that the vehicle has a good subjective feeling during energy recovery.
