Abstract :
Due to the short cycle life and small power density of battery in energy storage system for Hybrid electric vehicles (HEV), introduce the ultracapacitor as a solution, and design a hybrid energy storage system (HES) which combines the battery and ultracapacitor, so the HES made the best of characteristics of high energy density of battery and high power density of ultracapacitor. Firstly, study on discharging experiment of battery and ultracapacitor. Secondly, use the battery and HES as the power source respectively to carry out the experiment. Finally, compare and summary the results. The results show that ultracapacitor can absorb the peak power of load so as to protect the battery.
