Battery Swap Authorization via BMS Wireless Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The battery swapping process lacks effective monitoring for abnormal behaviors such as unauthorized and mistaken battery swapping, affecting the reliability of the process.
Innovation Solution
A vehicle control method that establishes a wireless communication connection with a battery management unit using a unique network address to prompt the vehicle to remain at the swapping station if abnormal behavior is detected, ensuring only authorized and correct batteries are swapped.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery swapping is performed without monitoring, then the swapping process is simple and fast, but the reliability and safety are compromised due to unauthorized or mistaken swapping
Solution Approach 1:
The control module establishes a wireless communication connection with the battery management unit before the battery swapping operation is completed. This preliminary connection verification ensures that the correct battery is installed and recognized by the vehicle system before allowing the vehicle to operate, preventing unauthorized or mistaken swapping without requiring complex post-swap monitoring infrastructure
Solution Approach 2:
The system implements a feedback mechanism where the control module continuously monitors the communication status between the battery management unit and the vehicle control system. If the battery management unit fails to respond or sends abnormal signals, the system receives feedback and prevents vehicle operation, thereby ensuring swapping reliability through simple real-time monitoring rather than complex verification procedures
2Reliability
If communication verification is performed between control module and battery management unit, then unauthorized swapping is prevented, but the swapping process time increases
Solution Approach 1:
The wireless communication connection is established and verified during the battery installation process itself, before the vehicle needs to depart. The control module checks the communication status and battery identification in advance, so that when the swapping is complete, the vehicle is already authorized to operate without additional verification delays
Solution Approach 2:
The battery management unit automatically provides identification and status information to the control module through the established wireless communication connection. This self-service mechanism eliminates the need for manual verification or complex external monitoring systems, allowing rapid authorization verification that does not add significant time to the swapping process
