Power supply management system, battery, charger, and unmanned aerial vehicle

Abstract

A power supply management system includes a selection control circuit, a controller, and a communication cable. The controller is connected to the selection control circuit and configured to control the selection control circuit to switch between a temperature measurement mode and an encryption certification mode. One end of the communication cable is configured to be communicatively connected to a battery, and another end of the communication cable is electrically connected to a communication interface and a temperature measurement interface of the controller. When the selection control circuit switches to the temperature measurement mode, the controller is further configured to read a voltage of a temperature measurement resistor of the battery via the communication cable. When the selection control circuit switches to the encryption certification mode, the controller is further configured to communicate with an encryption chip of the battery via the communication cable.
