蓄电池与超级电容复合电源功率控制研究

Research on power control of hybrid power of battery and ultra-capacitor

蓄电池高比能量与超级电容的高功率密度特性可优势互补构成蓄电池(B)+超级电容(UC)型复合电源。由于子电源性能不同,对此复合双电源进行瞬时功率研究,提出对蓄电池瞬时功率进行高频响应抑制而对超级电容功率输出不予限制的控制方案。系统采用分级管理解决方案并利用CAN通讯交互信息,进行功率分配以及标准工况实验以证明控制方案正确、可靠。此解决方案计算开销小易于工程化实现。

Battery （B） and ultra-capacitor （UC） can complement each other to constitute a hybrid power supply system due to high special energy of battery and high power density of ultra-capacitor. For the different properties of the two powers, instantaneous power of the dual power was studied, and a scheme was put forward that the battery＇s instantaneous power was suppressed but the power output of ultra-capacitor was not be restricted. An upper-lower layer management method was adopted and the two layers communicated through CAN. A series of experiments had been carried on to prove the correctness of the solution. Low computing cost is required with the solution, and the scheme is easy to realize engineering.
