摘要
超级电容器与蓄电池混合使用,可以充分发挥蓄电池比能量大和超级电容器比功率大、循环寿命长的优点,大大提升混合电源的性能。建立了蓄电池超级电容器并联的数学模型,定量地分析了混合电源性能的改善及其影响因素。对直接并联、通过电感器并联和通过功率变换器并联三种结构进行了研究和实验验证。实验表明,混合电源的功率输出能力大大提高了,蓄电池的放电过程得到了优化;通过功率变换器的并联结构具有较好的效果和实用性。
Sound performance can be attained through ultracapacitor/battery hybrid system, which makes the best of the characteristics of high energy density of battery and high power density and long cycle life of ultracapacitor. The mathematical model of the ultracapacitor/battery hybrid system was set up. The characters of it such as peak power enhancement were studied and the correlative factors were analyzed in the paper. Three main structures including directly connection, connection via inductance and power convertor were put forward and analyzed in experiments. Experiments show that the power capacity of the hybrid system was enhanced greatly and the discharging process of the battery was optimized. The conclusion that the connection via power convertor has sound performance and practicability is also gliven.
