High-altitude power supply system

Abstract

The invention relates to a high-altitude power supply system. The high-altitude power supply system comprises a closed box body, wherein the box body comprises an outer box body and an inner box body which is arranged in the outer box body, wherein multiple series-wound or shunt-wound batteries and a battery management system used for managing the multiple batteries are arranged in the inner box body; the multiple batteries are charged by a solar battery panel which is arranged outside the box body; a heating apparatus capable of keeping the temperature in the box body constant is arranged on the inner box body; and the heating apparatus is powered by the batteries or the solar battery panel. According to the high-altitude power supply system, the inner box body is heated by the heating apparatus to keep the temperature of the box body constant, to enable the battery to be adapted to the high-altitude severe environment condition and to ensure that the battery can work under the optimal temperature condition so as to improve the power supply efficiency and prolong the service life of the battery; the box body adopts a dual-layer structure; the heating apparatus in the inner box body can keep the temperature in the inner box body constant; the heat exchange between the inner box body and the external can be reduced due to the outer box body; and an effect of thermal preservation, thermal insulation, high-altitude resistance and low voltage is achieved.

Description

technical field [0001] The invention relates to a high-altitude power supply, specifically a power supply system for high-altitude flying objects. Background technique [0002] At high altitudes such as 6000 meters to 9600 meters, 8000 meters to 12600 meters or even higher, due to the relatively harsh environmental conditions, flying objects such as sounding balloons must have the ability to adapt to harsh environments during flight, such as cold resistance and heat resistance; The power supply system of these flying objects, as power supply equipment, is an essential and crucial component of high-altitude flying objects. When the flying object is flying under different driving conditions such as high speed, low speed, acceleration, deceleration, etc., the battery will be discharged at different rates, and heat will be generated at different heat generation rates. In addition to the accumulation of time and the influence of space, heat will accumulate, resulting in The temp...

AI Technical Summary

Problems solved by technology

When the flying object is flying under different driving conditions such as high speed, low speed, acceleration, deceleration, etc., the battery will be discharged at different rates, and heat will be generated at different heat generation rates. In addition to the accumulation of time and the influence of space, heat will accumulate, resulting in The temperature of the battery operating environment is complex and changeable

Most of the current high-altitude batteries use simple packaging, which has poor cold resistance, heat insulation and heat dissipation performance. For example, the batteries on the market work at high altitude for a long time, which will affect the service life of the battery and increase the cost of the battery.
