摘要

This paper contains supercapacitor-battery hybrid energy storage management strategies used in electric vehicles (EV). Supercapacitor is suitable for sustaining high charging or discharging current peaks and can provide peak power as demand. Using these two combinations battery pack durability is increased and extends the life of the battery. The battery is an important component of EV hence, the thermal management system is required to reduce the operating temperature to ambient temperature. Using a combination of supercapacitor-battery, a sudden load on battery shifted towards to capacitor and battery heating reduces. This reduces the charging time and increases vehicle performance. Moreover, the supercapacitor can store a large amount of energy in less time and also give high power to load without any degradation of life span. Further, the supercapacitor is capable to absorb energy more reliably than a battery during regenerative braking to store energy. In this paper, we combine the properties of the battery and supercapacitor pack for better energy management to improve vehicle driving range. The energy management is carried out concerning the case study of a hybrid energy storage system which consists of two energy storage systems which are lithium-ion battery and supercapacitor pack.
