Title:
REDUNDANT CIRCUIT FOR BATTERY, AND UNMANNED AERIAL VEHICLE AND METHOD FOR CONTROLLING BATTERY POWER SUPPLY THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/223741
Kind Code:
A1
Abstract:
Provided are a redundant circuit for a battery, and an unmanned aerial vehicle and a method for controlling battery power supply therefor. The circuit comprises at least two power supply branches connected in parallel and a power output end. Each power supply branch comprises a battery and a control subcircuit. The control subcircuit comprises a field-effect transistor (Q1) and a control chip (U1). An input end and an output end of the field-effect transistor are respectively connected to an output end of the battery and the power output end (VOUT). The control chip is connected to a control end of the field-effect transistor, and is used to continuously detect a voltage difference between the output end of the battery in the current power supply branch and the power output end, and to control turning on or off of the field-effect transistor according to the voltage difference. The present invention realizes seamless transition of power supply, thereby achieving redundant design for a battery.
