[0001] The present invention belongs to the field of medium and large unmanned aerial vehicles, and in particular, relates to an external power supply and power control module system for medium and large unmanned aerial vehicles. Background Art

[0002] At present, medium and large drones need to open the hatch and disconnect the battery in case of power outage in an emergency. At this time, the equipment will often be burned due to untimely power outage. After the drone is connected to the battery, the battery voltage needs to be checked through the ground station. Usually, the ground station is far away from the drone's take-off position, and the ground station controller often needs to inform the ground crew whether the battery needs to be replaced. During the factory debugging stage, it is often necessary to debug multiple drones, and generally use debugging batteries. When the debugging battery is tight, it will be used in turn. This process requires repeatedly opening and closing the hatch of each drone to plug in and out the battery, which is cumbersome and time-consuming. At present, the power supply of the payload is uncontrollable, that is, as long as the battery is connected, the payload will be powered, which is not conducive to the reasonable distribution of power.
