Abstract

A new type of flywheel energy storage structure-electromagnetic coupling flywheel energy storage system (EC-FESS) was proposed by considering the advantages of zero friction，none impact and adjustable speed of elec-tromagnetic slip clutch (ESC)． Power transmission route in vehicle deceleration state (braking or sliding) with EC-FESS was analyzed． Double closed-loop controller was designed to achieve the rapid response of magnetic pole shaft． Ｒecovery efficiency and its influencing factors of EC-FESS were quantitatively analyzed based on Simulink software． Through simulated test in platform，the influence of ESC stepless speed regulation on the energy recovery efficiency was verified． The results show that the stable value of energy recovery efficiency of EC-FESS is 33. 6% under different initial braking speeds，and EC-FESS and controller in Simulink are reasonable． In addition，energy recovery efficiency is the highest when ESC is adjusted．

Key words： flywheel energy storage; electromagnetic slip clutch; double closed loop controller; energy recovery efficiency
