摘要: 航空蓄电池在实际使用中会出现电池性能衰退与退化速率不一致,电池组容量与使用寿命降低,甚至可能出现严重的安全事故。针对电池单体不一致性和故障隔离问题,提出一种蓄电池电源系统容错体系结构和分级容错控制策略,提出基于电池单体动态重构的主动均衡管理新方法,设计基于"冒泡沉底(BS)择优上岗"的电池单体实时动态重构策略。开发容错航空镍镉电池电源原理样机,给出系统实验性能分析,实验结果表明所提出的系统技术方案可行有效,能够快速隔离故障失效电池单体,明显改善电池不一致性,提高了电池组容量利用率和剩余使用寿命。

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.

Key words: aircraft battery power, series battery, fault-tolerant battery system, reconfiguration control, active equalization management
