Abstract

The invention belongs to the technical field of unmanned aerial vehicles and discloses a system and method for predicting a remaining electricity quantity of a general lithium battery for a multi-rotor unmanned aerial vehicle. A general lithium battery remaining electricity quantity prediction device is turned on, control parameters are set according to the battery being detected, a lithium battery pack being detected is connected with the general lithium battery remaining electricity quantity prediction device, and operation off the system is started after a detection button is pressed. Via the system and method disclosed in the invention, an accurate remaining electricity quantity of the lithium battery can be obtained; the system is a piece of communication equipment, the remaining electricity quantity can be accurately predicted via detection of a chosen lithium battery pack model, prediction precision can reach as high as over 90% of a measured electricity quantity, and currentlyno such product for predicting the remaining electricity quantity of the battery is available. The system and method can help fill in market gaps, and flight of the unmanned aerial vehicle can be wellensured.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a system and method for predicting the remaining power of a universal lithium battery of a multi-rotor unmanned aerial vehicle. Background technique [0002] A gyroplane is a rotorcraft that utilizes rotor rotation to generate lift, an aircraft between a helicopter and an airplane; it is equipped with different numbers of propellers according to the type of motion, and has vertical take-off and landing, low-speed and low-altitude flight, simple, lightweight, Easy to hide and so on. In recent years, with the maturity of various technologies of rotorcraft, rotorcraft has begun to receive more and more attention. At present, the rotorcraft is mainly composed of a power system, a control system, an execution system, and a fuselage. At present, the power system of the vast majority of rotorcraft uses lithium batteries as the power source. Due to the inc...
