本研究設計一個完整的回收艙電源系統，使用可重複使用的二次鋰電池當作回收艙之電源，利用充電模組可快速補充電力，並提供回收艙主控電腦及科學酬載所需使用的電源。 於太空中心探空六號計畫-回收艙酬載，實作並驗證電源系統可在任務期間內克服所需經歷的惡劣環境，可以完全正常工作。並量測各模組在不同環境下的效能，將其作比較，用以估算系統所需的電源。 The main purpose of this thesis is to develop a power system of the recovery system for sounding rocket. Using the reusable lithium battery as the power source of the recovery system, and, using the recharging module which can recharge the battery efficiently for time-saving. The reusable lithium battery supports power to the main controller of the recovery system and space instrument. In the Sounding Rocket VI mission of National Space Organization, the system has been implemented and proved that after the rocket lunching progress, this system can overcome wicked environment and still work normally. Also, we estimate the power that the system needs by using the measured data of efficiency under different environments.
