Design and Research of Battery Capacity Detection System for Plant Protection Unmanned Aerial Vehicle
Lithium-ion battery is the main power of small plant protection UAV,affected by the chemical reaction inside the battery,its use for a period of time will appear capacity attenuation,resulting in a decline in the working time of small plant protection UAV,affecting agricultural production efficiency.In order to help users understand the remaining battery capacity in time,this paper designs a battery capacity detection system for planting security UAV based on STM32F103RCT6 single chip computer.The system detects the battery capacity by current integration method.The experiment shows that the system can accurately measure the discharge capacity of the battery.
