摘要:

为解决电机再生制动回收系统中能量回收效率受电池电极“活性物质”化学反应速度影响的问题,利用飞轮储能的高瞬时功率、高效率、长循环寿命及快速响应等特点提出了一种电磁耦合式飞轮能量回收系统。分析了汽车加速、减速工况下该系统的能量转换路线。借助Simulink软件定量分析了电机再生制动能量回收系统和电磁耦合式飞轮能量回收系统在减速-巡航过程中电池回收的能量。搭建模拟运行试验平台,验证了电磁耦合器各端口的能量传递特性。结果表明:电磁耦合式飞轮能量回收系统可以将55.93%的汽车动能直接储存于飞轮中,44.07%的能量经电磁耦合器电气端口储存于电池中,降低了电池参与能量回收过程的程度。

Abstract:

The energy recovery efficiency of motor regenerative braking recovery systems is affected by the chemical reaction speed of the battery electrode "active substance.?" To address this issue, an electromagnetic coupling flywheel energy recovery system (ECFESS) is proposed herein owing to the high instantaneous power, high efficiency, long cycle life, and fast response of flywheels. The energy conversion route of the system under vehicle acceleration and deceleration was analyzed. Simulink was employed to analyze the energy recovered from batteries in the deceleration-cruise process of the motor energy recovery system and ECFESS. Through the simulation test platform, the energy transfer characteristics of each port of the electromagnetic coupler were confirmed. The result of ECFESS shows that 55.93% of the vehicle kinetic energy is directly stored in the flywheel, and 44.07% in the battery through the electrical port of the electromagnetic coupler, reducing the degree of the battery participating in the energy recovery process.

Key words: hybrid powertrain, flywheel energy storage, structural characteristics, energy recovery
