Title of Paper:Fault-tolerant battery power supply for aircraft and its active equalization management

Journal:Hangkong Xuebao

Abstract:In practical use, battery cells will have different problems including performance degradation, different degradation rate of cells, capacity and service life degradation, and even occurrence of serious accidents. To solve the problems of inconsistency of battery and fault isolation requirement, a fault tolerant architecture and hierarchical fault tolerant control strategy for battery power supply are proposed, a method of active equalization management based on dynamic reconfiguration of cells is presented, and a real-time dynamic reconfiguration strategy based on Bubble Sort (BS) for battery cells is given. A prototype of the fault tolerant Ni Cd battery power system for aircraft is developed. The experimental results show that the proposed system scheme is feasible and effective, and fault cells can be isolated quickly to greatly reduce the inconsistency of battery cells and improve the capacity and remaining useful life of the battery power system. © 2018, Press of Chinese Journal of Aeronautics.
