Lithium battery constant-temperature thermal-insulating bag for unmanned aerial vehicle

Abstract

The invention discloses a lithium battery constant-temperature thermal-insulating bag for an unmanned aerial vehicle, and relates to the technical field of the unmanned aerial vehicle. The lithium battery constant-temperature thermal-insulating bag comprises a thermal-insulating bag body, a temperature acquisition system, a heating system and a main control system. According to the thermal-insulating bag provided by the invention, a foldable thermal-insulating structure with a cubic or cuboid-shaped appearance characteristic is prepared by the special thermal-insulating bag and high-efficiency electric heating wires; the data of multiple temperature sensors is collected by a microcontroller; and the temperature of the apparatus is adjusted and maintained at the normal value by controlling the operating state of the electric heating wires.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle lithium battery constant temperature heat preservation bag. Background technique [0002] The current drones cannot normally perform flight missions in low temperature environments. The main bottleneck is that the batteries are abnormally discharged at low temperatures. The industry urgently needs a device to change the status quo. [0003] Chinese patent application number 201410006447.X discloses a lithium battery heat preservation device, which includes a body and a cover, and the cover is set on one end of the body. The body includes a heat conduction layer, a water bag layer, a top insulation layer, a bottom insulation layer and an outer shell. The heat conduction layer has at least one storage cavity for storing lithium batteries. The water bag layer is wrapped around the heat conduction layer. The water bag layer mainly has a fi...

Problems solved by technology

Although this kind of device can play a certain function of heat preservation and heat insulation, it does not have the function of self-heating. The temperature in this kind of heat preservation device will continue to drop. When it reaches a certain level, it will easily cause the operation of the lithium battery to be unstable. And the corrosion resistance of the device is insufficient

[0004] Chinese patent application number 201210492382.5 also discloses a low-temperature heat preservation control device for lithium battery packs, which is developed to address the disadvantages of poor discharge performance of lithium battery packs at low temperatures (below -10°C)

Although the above
