随着大功率脉冲功率负载在船舶上逐渐增多，采用阀控铅酸蓄电池作为供电动力源时，须研究和明确其供电能力影响因素和边界条件，辅助供电判断和操作。本文分析指出内阻水平和荷电量是影响阀控铅酸蓄电池脉冲负载供电能力的主要因素；通过建立阀控铅酸蓄电池对脉冲功率负载供电仿真模型，仿真研究了阀控铅酸蓄电池在不同内阻水平、不同荷电量以及单次和连续供电情形下的边界，并据此给出在工程应用时须合理确定蓄电池内阻水平、荷电量范围以及须实时动态监测蓄电池内阻水平和荷电量的建议。
With the increase of pulse power loads on ships, when they′re supplied by VRLA batteries, the influencing factors and supply boundaries have to be considered to help for power supply decision. In this paper, the internal resistance and state of charges of VRLA batteries are discovered as the main influencing factors for the power supplication ability of VRLA batteries. By considering and building the pulse power load supply simulation model of VRLA batteries, the power supply boundaries of VRLA batteries are researched when VRLA batteries are in different internal resistances and state of charges under one single time and several times. What′s more, the suggestion of appropriate controlling and monitoring of VRLA battery′s internal resistance and state of charge are made when in engineering practice.
