A circulating energy power supply system suitable for high-altitude balloons

Abstract

An embodiment of the present invention provides a cycle energy power supply system suitable for high-altitude balloons, including: a solar array, an energy storage battery pack, an energy manager and a distributor, and the energy storage battery pack includes a main energy storage battery pack and an emergency energy storage battery Group. The solar battery array is used to convert solar energy into electrical energy, and the energy storage battery pack is used to supply power to the load during the period when there is no sunlight; the energy manager is used to track the maximum power of the solar battery array to charge the energy storage battery pack and supply power to the load; the distributor is used for Convert the bus voltage of the solar battery array and the energy storage battery group to different voltages, and automatically switch to the emergency energy storage battery group when the main energy storage battery group fails. The invention utilizes a cycle energy power supply system composed of solar cells and energy storage batteries to realize the energy balance of the high-altitude balloon energy system, effectively prolong the dwell time of the high-altitude balloon, and provide stable and reliable energy supply. The cycle energy power supply system is also applicable to other low-altitude balloons. Dynamic high-altitude long-endurance flight platform.

Description

Technical field [0001] The present invention relates to the field of energy technologies, and in particular, to a circulating energy power supply system suitable for high-air balloons. Background technique [0002] The float refers to an aircraft that utilizes floating medium such as hydrogen or helium. The float can be roughly divided into several categories including balloons, high-altitude balloons and airships. In recent years, the unique resource advantage of approaching space has become a hot spot in various countries. High air balls are generally operated in the middle and lower part of the adjacent space, from the range of 20km-50km of the ground, belonging to the airborne float, using high-altitude balloon to carry a payload to cosmic rays and electromagnetic radiation research, communication, interior observation, and There is a huge application value in terms of remote sensing. [0003] Compared to the exploration rocket, high air ball has a lower flight speed, better ...

Problems solved by technology

[0004] Most of the existing domestic high-altitude balloons are powered by energy storage battery packs, but the energy storage battery pack cannot continue to be used when the power is exhausted, and the long-endurance flight of high-altitude balloons cannot be realized, and long-endurance flight has great impact on the application of high-altitude balloons. greater meaning
