【摘要】：作为化学储能的主要方式,蓄电池在功率密度、充电速度、能量转换效率、寿命等方面存在着严重的不足,致使许多以蓄电池为主动力的新型产业存在着技术瓶颈。而超级电容作为一种新型的储能方式,恰恰在这些方面具有优良的特性,与蓄电池形成了良好的性能互补。通过分析这两种电池的基本性能,设计了以蓄电池为主动力系统,以超级电容器为辅助动力系统的复合电源,阐述了复合电源的拓扑结构及功率分配控制方法。研究结果表明:采用复合电源工作的电源设备,相比于单一蓄电池电源的情况,具有更好的动力性和可靠性,同时还具有蓄电池的保护作用,有效地提高了系统的寿命。
[Abstract]:As the main way of chemical energy storage, batteries have serious shortcomings in power density, charging speed, energy conversion efficiency, life span and so on. As a result, there are technical bottlenecks in many new industries which are mainly powered by batteries. As a new type of energy storage method, super capacitor has excellent characteristics in these aspects, and it is complementary to battery. By analyzing the basic performance of the two kinds of batteries, a composite power supply with battery as the main power system and supercapacitor as the auxiliary power system is designed, and the topology structure and power distribution control method of the composite power supply are expounded. The research results show that the power supply equipment with compound power supply has better power performance and reliability than the single battery power supply, and it also has the function of battery protection, which effectively improves the life of the system.
