摘要
为了解决高轨卫星锂电池地面充电问题,从充电需求着手,提出一种基于恒流和恒压方式的阶梯式降电流充电方法,并设计了自主充电软件。该软件已在某高轨卫星测试中应用,135 Ah电池组充满耗时约10 h,温升小于8℃。应用结果表明,采用阶梯式降电流充电方法能安全有效实现卫星用锂电池地面充电,并可推广应用。
To solve the problem of GEO satellite Li-ion test, analyzing satellite Li-ion battery charging demand on the ground, a charging method in step-current based on constant-current/constant-voltage was put forward, and a set of auto-recharging software was designed. The proposed software was used in GEO satellite testing, the charging time of the battery(SAFT, 135 Ah) is 10 h, and the temperature rise to less than 8 ℃. The results show that above charging strategy can safely and efficiently complete the test for satellite Li-ion battery. The charging strategy has now been popularized in multi-satellite testing.
