基于超级电容的超微型电动车制动能量回收系统研究

hetraditional braking energy recovery system with battery asenergy storage, Due to frequent charge-discharge affecting the service life of motor and low energy recovery efficiency at low speed cannot be directly used in the SuperMicro-electric vehicles. This paper presents a methodof using super capacitor as the energy storage component to overcome this defectand improve the efficiency of braking energy recovery.Test bench is builded and braking energy recovery detection system is designed.This paper is verified by research of braking energy recovery system in the energy recovery efficiency under different working conditions.Braking energy recovery efficiency can reach 13.7%.Tests showed that this method has a certain practical value.
