A Low-Cost Supercapacitor Battery Design for Cube Satellite Application
摘要
The reliable operation of satellites and their payloads hinges on a robust power system and an efficient energy storage unit capable of consistently meeting energy demands throughout a satellite’s lifecycle. This paper explores the development of an economical supercapacitor-based battery system tailored for CubeSat applications. It presents a highly efficient design that leverages readily available commercial off the-shelf (COTS) supercapacitors. In recent years, small satellites, particularly CubeSats, have demonstrated impressive performance levels akin to their larger counterparts. They have become instrumental in pioneering new technologies, clean energy solutions, and environmentally friendly materials for sustainable energy storage systems, particularly in the realm of power systems, energy storage, and high-power consumption requirements. As a result, there is a growing interest in storage systems that rely either entirely on supercapacitors or incorporate them in a hybrid fashion. Supercapacitors are favoured for their ability to deliver high power rapidly, quick recharge capabilities, and compact form factors. The designed supercapacitor-based battery system employs a series connection of two 2.7 V 500 F supercapacitors, equipped with a DC–DC converter, charge and discharge control system, as well as mechanisms for balancing and overvoltage protection. This innovative configuration empowers the CubeSat with a tailored energy supply for specific mission objectives and stands as a potential solution to address power supply interruptions.
