Use of the infrared thermography method to develop discharging rules for lithium polymer batteries

Abstract

The results of using the infrared thermography method for studying the discharging process in lithium polymer batteries have been presented in this article. The general rules of discharging a lithium polymer battery are shown in the maximum mode of drone engine operation, namely, regardless of the external temperature, the process of heating the battery has a nonlinear character with a clear maximum temperature. In the course of operation of unmanned aerial vehicles under reduced temperatures, special attention is required before making a decision to connect an additional battery and fulfill the “home” command. Testing the battery temperature during a flight with an autonomous control system can be carried out not by a thermographic camera, but by means of temperature sensors.
