摘　　要：以现有新能源为主、锂电池组为储能装置的船舶电力系统的锂电池管理系统为研究对象,针对其可靠性不高和不具备冗余特性而不适合船舶应用场合的问题,提出一种由双机主从与三线路传输共同构成的多重冗余方案,并根据马尔科夫过程理论对所设计的系统进行可靠性分析。试验结果表明,采用多重冗余方案的锂电池管理系统,除正常工作时能实时监视电池组状态信息外,故障时仍能选择不同冗余方式确保系统可靠工作,从而验证了所提出的具有高可靠特性的多重冗余方案的正确性与可行性。这种具有多重冗余高可靠性特性的锂电池管理系统,在新能源船舶中具有良好的应用前景。Due to the existing lithium battery management systems（BMS） with none-redundancy and low-reliability in marine power system based on new energy and lithium batteries, a multi-redundancy marine-BMS, which is composed of the master/slave hot-standby redundancy and three transmission line redundancy, is proposed to meet the marine safety applications in the paper. Then, the reliability analysis is established by using the theory of Markov process. The experimental results exhibit that the multi-redundancy marine-BMS can even work well in failure by choosing different redundancy modes, besides real-time monitoring the battery status in normal working mode. The feasibility and reasonability of the proposed multi-redundancy marine-BMS have also been validated by the designed experiment. Moreover, the high reliability multi-redundancy marine-BMS have good prospects for the applications in new energy ship.
