【 摘 要 】

According to the characteristics of ultracapacitor (UC) and lead-acid battery, a novel and simple circuit of hybrid power system (HPS), which is consisted of UC group and battery set, is designed to realize the basic strategy: to use the UC group to process all solar energy and most of the peak current. However, since the battery set has a much higher energy density than the UC group, it is used to supply power when vehicle run on cruise speed. Both UC group and battery set supply the driving power for vehicle start-up, acceleration and climbing. The results of simulation show that the proposed novel and simple circuit, which is composed of UC group and battery set in parallel, can realize the reasonable energy use of vehicle.
