摘要
75 Ah锂离子蓄电池作为IGSO卫星储能电池得到在轨应用,数据表明两组蓄电池在轨性能一致性高,单翼蓄电池组内22串电池的电压离散度小于20 m V,蓄电池温度梯度小于3.5℃,一个长光照期内,蓄电池荷电态保持在70%~80%,进行补充充电3次。蓄电池在轨实践表明蓄电池设计合理,性能稳定可靠,在轨管理方法合理有效。
The 75 Ah lithium ion batteries as the IGSO satellite storage battery were working on the orbit. The dataindicates that the parameter of the batteries is conformal to each other. The difference of voltage between the 22 cellpacks in one module was less than 18 mV. The temperature gradient in the battery was less than 3.5 ℃. The SoC ofthe battery during the solstice season was 70%~80% and the battery needed to be supplemental charged3 times.The application of the battery on orbit indicates that the performance is stable and reliable, and the managementmethod is convenient.
