Application of the Battery Management System in a Multi-rotor Unmanned Aerial Vehicle

The state of charge of a battery depends mainly on its capacity and the discharge current. This is an important parameter for the battery that protects it from deep discharges, overcharging and estimates its remaining energy. Thus, the more precise the estimation of the state of charge, the more energy that the battery can provide is better exploited. This can be part of a possible energy optimization of the UAV and the control of its performance. This article presents generalities about the battery and its management system mainly the mathematical methods for SOC estimation, as well as an application on Rotary-wing UAVs with a model of energy consumption.
