| 摘 要： | 基于空间用单一压力容器镍氢电池的传热传质以及电化学反应机理,建立三维、非稳态的电池传热模型.这个三维、非稳态电池传热模型包括压力容器在内的全部区域.采用有限容积法对单一压力容器镍氢电池的温度场进行数值模拟,模拟得到的结果与试验结果吻合良好.基于这个模型,提供电池的两种结构设计方案,并根据模拟的温度场结果评价这两种方案.在不改变电池输出功率的情况下,电池极堆位于电池中部时温度场的最大温差最小,尽量大的内径可以获得更小的最大温差.该三维、非稳态电池传热模型可用于镍氢电池的工程设计和参数优化.

| Abstract: | Based on the mechanisms of heat and mass transfer,electrochemical reaction in a single space-use pressure vessel nickel-hydrogen battery,a three-dimensional,non-steady state heat transfer model of the battery is developed.This model includes all the parts of a battery including the pressure vessel.The temperature field of the battery is simulated by using the finite volume method and the simulation results tally with the experimental data.Based on this model,two kinds of battery design scheme are provided a... |
