Embodiment Construction

[0039] At present, the battery terminal adopts the anti-sparking plug of the male cross-shaped elastic structure, except that the resilience performance of the battery terminal is easily deteriorated, and the position of repeated contact with the drone is easy to fall outside the anti-sparking ring. In addition to the spark phenomenon, in the long-term operation process, the anti-spark resistor provided on the battery is affected by the plugging stress and environmental corrosion, causing the metal terminal of the anti-spark plug to burn and turn black, and it will be effective quickly, and then Loss of anti-sparking function.

[0040] Further, the drone uses the ESC to prevent the spark phenomenon, but those skilled in the art can understand that the position where the most capacitors are used inside the drone is the ESC. Due to its own characteristics, the ESC can only start slowly with 1 to 2 large electrolytic capacitors inside. Although the capacitance of other capacitors...

Abstract

A power-on slow start device includes a switch circuit and a processing unit connected with the switch circuit. Among them, the switch circuit and the processing unit are used to connect to the same terminal of the battery and the load, and the initial state of the switch circuit is the disconnected state. When the processing unit compares that the voltage of the same terminal of the battery and the load is less than or equal to the first preset threshold, the control switch circuit is turned on after a delay of a preset time, so as to make the battery supply power to the load. In actual use, the slow start of power supply to the UAV for the load is realized, thereby avoiding the phenomenon of discharge and ignition. It also relates to a battery assembly, an unmanned aerial vehicle and a power-on slow start method.

Description

technical field [0001] The invention relates to the technical field of circuits, and in particular, to a power-on slow-start device, a battery assembly, an unmanned aerial vehicle and a method. Background technique [0002] Most heavy-duty drones (take-off weight greater than or equal to 20kg) mostly use high-voltage and high-capacity batteries, and the discharge current of the battery is huge, generally close to several hundred amperes. Therefore, the battery required by the drone has the characteristics of high voltage and high current, so most of the batteries use non-smart batteries, which cannot perform switching functions, resulting in the battery being charged for a long time, so that when the battery is connected to the drone, it is prone to hot swapping scenarios. . [0003] When the battery terminal is close to the bus terminal of the drone, due to the large amount of capacitance in the internal circuit system of the drone (load end), the impedance of the input te...
