摘要
嫦娥二号卫星经历8个月的环月飞行,完成了对着陆点"虹湾"区域的详查等工程目标,在成功绕飞拉格朗日L2点后,又完成与小行星"图塔蒂斯"交会的再拓展任务。嫦娥二号卫星装备了氢镍电池,按设计用于协助发射、地月转移、环月飞行和月食过程的辅助供电。对于氢镍电池的要求包括在环月轨道上至少供电6个月并支持大电流脉冲,例如点火过程。为了确定氢镍电池设计能够符合这些要求,对嫦娥二号卫星任务中使用的氢镍电池组进行了地面测试,该电池组由17节48Ah的单体电池构成,用于地面测试的电池部件与当前装配在嫦娥二号卫星上的电池组相同,通过地面测试,氢镍电池被证明满足这项任务的要求,并对支持按计划延长期的任务留有空间。
After 8 months＇ lunar orbiting flight for detailed exploration of ＂Sinus Iridum＂ area, the CE-2 satellite had fronted to L2 point and completed the observation of L2 point, then completed the stretch assignment for rendezvous with the small planet Toutatis. The CE-2 satellite was equipped with nickel-hydrogen battery, which supplied necessary power supply auxiliary during the phases of launching, transferring, lunar orbiting, and eclipse period. The nickel-hydrogen battery was required to work for at least 6 months and supported the large pulse discharge current. To determine the battery design would meet the use requirement, large amount of ground tests were done to the nickel-hydrogen battery of CE-2 satellite. The ground test battery was composed by 17 cells 48 Ah, which were the same as those assembled to CE-2 satellite. Through ground test, the nickel-hydrogen battery design was proved to meet the mission requirement, and had adequate space for further expanded missions.
