摘要: 为了提高水下航行器的动力可靠性, 从水下航行器用锂离子动力电池组的连接方式入手, 分析了串联和并联复合连接方式的可靠性, 计算出可靠性最高的电池连接方式。研究结果表明, 先并联后串联的连接方式在实际应用中具有更高的可靠性。最后探讨了并联电池组在共载模式下的可靠性, 这种模式的建立对实际应用中水下航行器动力可靠性的提高具有一定的参考价值。Abstract: To improve the reliability of power system of an underwater vehicle(UV), in view of the connection mode of Li-ion battery pack of an electric-power UV, the reliability of composite connection of series and parallel connections is analyzed. Different connection modes are calculated, and the mode with the highest reliability is obtained. It is concluded that the connection mode of first series then parallel connection can achieve higher reliability. In addition, the reliability of parallel battery pack is calculated and analyzed based on the load-sharing mode.
