Abstract

The invention discloses an air cooling heat dissipation system of a soft package battery pack for an unmanned aerial vehicle and a control method thereof. The air cooling heat dissipation system comprises a shell, a plurality of battery cell monomers, a plurality of heat conduction silica gel pads, a temperature sensor, an air inlet fan, an air outlet fan and a controller, wherein the battery cellmonomers, the heat conduction silica gel pads and the temperature sensor are arranged in the shell; the air inlet fan and the air outlet fan are arranged outside the shell; and the temperature sensor, the air inlet fan, the air outlet fan and the battery pack are all connected with the controller. The air cooling heat dissipation system is reasonable in structural design and good in heat dissipation effect, the rotating speed of the fan and the output power of the battery pack can be controlled according to the temperature of the battery pack, the battery pack is cooled and located within a temperature suitable range, and normal flight of the unmanned aerial vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of soft-pack battery packs for unmanned aerial vehicles, in particular to an air-cooled heat dissipation system and a control method for the soft-pack battery packs for drones. Background technique [0002] Compared with cylindrical batteries and prismatic batteries, soft-pack battery packs have a lighter casing and a higher proportion of active materials, so it is easier to achieve higher energy density. It is mainly used in some occasions that require a high volume and weight of the battery pack, such as the battery pack of a drone. [0003] However, in the existing pouch battery pack, the cells are generally in close contact, which adversely affects the heat dissipation of the battery. Especially in the case of high rate discharge, the temperature is often too high. [0004] At present, the heat dissipation methods of pouch battery packs generally include air cooling, water cooling, phase change materia...
