UAV Charging Platform for Autonomous Battery Recharging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous cruising unmanned aerial vehicles require manual battery replacement, limiting their autonomous flight duration and increasing labor costs, as they cannot charge without landing and disassembling the battery.
Innovation Solution
A charging platform with a control unit, charging switch, and power supply that connects to the unmanned aerial vehicle's power receiving interface and battery pack, allowing autonomous charging without manual battery replacement by forming a charging loop and using the battery pack to power the control unit for intelligent charging management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If manual battery replacement is used for charging, then the unmanned aerial vehicle can be recharged, but labor costs increase and intelligence decreases
Solution Approach 1:
The unmanned aerial vehicle autonomously completes the charging process by automatically docking with the charging platform and establishing electrical connection through the power receiving interface. The battery pack remains installed in the vehicle throughout charging, eliminating manual intervention and enabling self-service recharging that extends autonomous flight duration without increasing labor costs.
2Duration of action of moving object
If manual battery replacement is used for charging, then the unmanned aerial vehicle can be recharged, but operation time is lost during landing and battery replacement
Solution Approach 1:
The charging process is designed to occur while the unmanned aerial vehicle remains in its operational position without requiring landing or battery removal. The power receiving interface establishes continuous electrical connection with the charging platform, allowing charging to proceed concurrently with minimal disruption to operational readiness, thereby reducing time loss and maintaining continuous useful action.
3Extent of automation
If the control unit is powered by the battery pack during charging, then autonomous charging control is enabled, but the battery pack must supply power during charging
Solution Approach 1:
The battery pack is pre-charged to sufficient capacity before the charging operation begins. During the charging process, the battery pack temporarily supplies power to the control unit to enable autonomous charging control, but this energy consumption is minimal compared to the total battery capacity. The preliminary charging state ensures that the brief energy expenditure for control does not compromise the overall charging objective or extend the charging duration significantly.
