Problems solved by technology
Due to the different internal resistance characteristics of different battery packs, charging this type of battery pack directly through the working circuit in reverse is likely to cause uneven current distribution and damage the battery pack.
However, in the current charging method for drones, it is necessary to take out the battery pack and connect it to a charger to charge this type of drone battery pack. The charging process is too cumbersome.

Embodiment Construction
[0037] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
[0038] The power supply used by medium and large multi-rotor drones is generally composed of multiple battery packs connected in series and parallel to meet the voltage and current supply required by the drone. Due to the different internal resistance characteristics of different battery packs, charging such a battery pack directly through the working circuit in reverse is likely to cause uneven current distribution and damage the battery pack. However, in the current charging method for drones, it is necessary to take out the battery pack and connect it to a charger to charge this type of drone battery pack, and the charging process is too cumbersome. Based on this, the inventor of the present application proposes the present application to solve the above-mentioned problems.

Description
technical field [0001] The present application relates to the fields of mechanical structure design and electrical control, in particular, to an automatic switching device and method for multi-battery pack charging circuits of an unmanned aerial vehicle. Background technique [0002] At present, the power supply used by medium and large multi-rotor drones is generally composed of multiple battery packs connected in series and parallel to meet the voltage and current supply required by the drone. Due to the different internal resistance characteristics of different battery packs, charging such a battery pack directly through the working circuit in reverse is likely to cause uneven current distribution and damage the battery pack. However, in the current charging method for drones, it is necessary to take out the battery pack and connect it to a charger to charge this type of drone battery pack, and the charging process is too cumbersome.
