Lithium-ions Battery Pack
Product introduction
Based on industrial single-cell batteries, No.18650 and No.21700 Cylindrical Battery as well as the Square Battery with a large capacity, Li-ion battery packs for satellites are assembled by the mass production line after strict screening of these industrial components. Mature industrial off-the-shelf products, along with the leading space environmental adaptability design and sufficient tests in the lab, contribute to a diversified product line, which can meet different demands by customization. Now it covers a bus voltage selection of 16V/28V/42V and a power capacity ranging from 20Ah to 110Ah.
Being upgraded by three generations, a dozen sets of solar arrays have served in orbit with good performance, among which the earliest one has worked properly for nearly 8 years.
