Application and Verification of ultra-high Rate Battery Packs for Micro-nano SAR Satellites

Abstract

Driven by the restrictions of Low-cost, high load ratio and the multi-functional developments of SAR load, customers proposed higher requirements for light and miniaturized energy storage packs with high power characteristics. This paper introduces a light-weight and ultra-high power lithium-ion battery pack suitable for micro-nano SAR satellites, Which integrates an ultra-high-power battery module and a power charger. This battery pack can support continuous high power supply of 20C/minutes-discharge, besides automatically shutdown and unlock for power charge functions, which have been demonstrated successfully onboard for some certain small SAR satellites.
