Ultracapacitor-battery hybrid power supply can effectively bring the excellence of high energy density of battery, and long cycle life and quick chargedischarge of ultracapacitor, which can significantly increase the peak output power of the power supply. The mathematical model of the ultracapacitor-battery hybrid power supply was set up. The factors which affected the peak output power of the ultracapacitor-battery hybrid power supply were systematically analyzed and through experiments the peak output power performance of ultracapacitor-battery hybrid power supply was verified. The analysis and experimental results show that the peak output power of ultracapacitor-battery hybrid power supply is related to the pulse duty cycle of the load, pulsating load cycle, the internal resistance of ultracapacitor and battery, the capacity of ultracapacitors,and the parallel branch number of ultracapacitor. The peak output power of ultracapacitor-battery hybrid power supply is significantly improved comparing with battery.
