EMS Investigation of Compound Power Supply for PEV

It is still much to be desired for battery to power alone as energy storage system in pure electric vehicles (PEV). A compound power supply made up by batteries and ultracapacitors (UCs) is proposed and a rule-based energy management strategy (EMS) is designed in order to improve the working efficiency and extend the cycle-life of the battery. Simulation results from ADVISOR show that PEV with compound power supply is more energy efficient and dynamic performance is better compared with PEV with battery only. In addition, the battery current drops greatly, which will help extend the cycle-life of the battery.
