中文摘要:
      在燃料电池与蓄电池混合动力载人潜水器中,蓄电池的类型及容量是影响混合动力系统的响应特性、安全性、体积、重量的重要因素。首先分析影响蓄电池容量的各个因素,然后找出影响辅助蓄电池组功率及容量的主要因素,从而指导蓄电池的选型及容量配置。为了验证估算容量值是否满足系统要求,开展了铅酸蓄电池放电电流与容量的建模,提出了基于状态的燃料电池与铅酸蓄电池的功率分配方法及铅酸蓄电池SOC的估算方法,最后基于MATLAB GUI搭建了铅酸电池容量验证系统,通过该容量验证系统,不仅可对混合动力系统中辅助蓄电池配置方案进行校核并优化设计,还可为系统是否设置重载询问提供依据。
英文摘要:
      The response characteristics, safety, volume and weight of the hybrid power system are affected by the capacity and types of the battery if the Fuel cell and battery hybrid system is used by the manned submersible. First, the factors affected the battery capacity are analyzed. Second, the power and energy of the battery is determined and the specification of the battery can be chosen. In order to verify whether the capacity of the lead-acid battery satisfy the system"s requirements, the relation model of lead-acid battery discharge current and capacity is made. The power allocation method of the Fuel cell and lead-acid battery is designed. At last, the capacity verification system of the lead-acid battery is made based on the MATLAB GUI. Through the capacity verification system the working time of the battery can be calculated in a given situation.
