摘要
通过分析飞轮储能系统的传动特性,研究能量回收过程中储能飞轮的动态响应过程,提出了一种新型电动式飞轮混合动力系统结构.揭示了配备飞轮储能系统的车辆制动过程中动力传递路线及能量流关系,并确定了飞轮储能装置的能量回收效能评价指标.在此基础上,通过搭建的台架系统完成了能量转换特性试验.试验结果表明:采用小功率的调速电机进行齿圈调速,可降低能量回收过程中传动系统的冲击度,提高储能飞轮能量回收率,净能量回收率趋于稳定值33%,为车用飞轮储能系统的开发提供理论依据.
A novel electrical flywheel hybrid system was proposed through analyzing the dynamic response of energy recovery process and the transmission characteristics of flywheel energy storage system.The power transmission process and energy flow of the vehicle with flywheel energy storage system was elaborated during braking.Energy recovery performance evaluation indexes were put forward,and the energy conversion characteristic test was conducted by experiment rig.The test shows that the use of low-power motor speed control for gear ring can reduce the impact sensitivity of energy recovery during transmission,and improve the energy storage rate.The net energy recovery rate tends to be stable at 33%.The research results can provide the theoretical basis for the research of flywheel energy storage system for vehicular applications.
