摘　　要：氢镍电池内部压力可以直接反映电池的荷电状态,因此压力作为氢镍电池的充电控制方式在国外卫星中广泛应用。介绍了压力模块的原理与设计,对比了氢镍电池的充电控制方法,对压力充电控制中压力与荷电状态、温度和循环寿命关系等方面进行了研究,探讨了国内外压力充电控制方式。压力模块在氢镍电池充电控制中的应用表明,压力充电控制为氢镍电池的充电控制提供了一种有效的方法。Nickel-hydrogen cell pressure can reflect state of charge directly, thus pressure as charge control method of nickel-hydrogen cell is used widely in international satellites. The principle and design of pressure module was introduced, three kinds of charge control methods were compared. The aspects such as relations between pressure and state of charge, temperature and cycles in charge control were studied. International pressure charge control methods were also discussed. The application of pressure module indicates that pressure charge control provides the effective method to nickel-hydrogen cell.
