【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.更多还原
