Robot Charging Pile Control Loops for Safe Adaptive Battery Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging piles for robots are unsafe due to uncontrolled charging voltage output, leading to potential short circuits and electric shocks, and they lack adaptability to different robot battery types, resulting in frequent replacements and wastefulness.
Innovation Solution
An intelligent charging pile with a charging loop, a protecting loop, and a communication control loop is designed. The communication control loop acquires battery information from the robot, adjusts charging parameters, and controls the protecting loop to ensure safe charging. This setup allows the charging pile to adapt to various robot battery types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the charging pile is connected with a power supply and outputs charging voltage, then charging function is provided, but safety issues arise causing short loops and electric shocks
Solution Approach 1:
The protecting loop performs preliminary detection of the robot's charging readiness and communication loop verifies battery information before the charging loop activates voltage output. This preliminary action sequence prevents unsafe charging conditions from occurring in the first place
Solution Approach 2:
The protecting loop acts as an intermediary safety layer between the power supply and the robot, detecting charging conditions and controlling the charging loop's activation. The communication control loop serves as another intermediary that verifies battery compatibility before allowing charging parameters to be applied
2Reliability
If one charging pile is equipped for one robot with specific battery type, then charging is achieved, but adaptability to different robot battery types is poor requiring frequent replacements
Solution Approach 1:
The communication control loop is designed to universally recognize and identify different robot battery types through communication protocols. The charging loop can universally adapt its charging parameters based on the detected battery type, making a single charging pile serve multiple robot models without frequent replacements
Solution Approach 2:
The charging parameters are dynamically adjusted based on the robot's battery information acquired through the communication control loop. The system transitions from static fixed parameters to dynamic adaptive parameters that change according to the specific battery type being charged
3Device complexity
If charging parameters are fixed for specific robot battery types, then charging control is simple, but flexibility to adjust for various battery types is lost
Solution Approach 1:
The communication control loop establishes a feedback mechanism that acquires battery information from the robot and automatically adjusts charging parameters accordingly. This feedback loop eliminates the need for manual parameter adjustment while maintaining simplicity in operation
