Battery Swap Verification via Wireless BMS Connection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The battery swapping process for electric vehicles 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 and system that involves acquiring the network address of a target battery's management unit, establishing a wireless communication connection, and transmitting a prompt signal to allow the vehicle to leave the swapping area only if the battery is in a normal state, ensuring proper battery swapping and preventing low-quality batteries from being installed.
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 is poor due to unauthorized and mistaken swaps
Solution Approach 1:
The system performs preliminary actions by establishing wireless communication connection and verifying battery identification information before allowing the battery swapping operation to complete. The control module checks whether the target battery matches the vehicle requirements before enabling the vehicle to leave the swapping area, preventing unauthorized or mistaken swaps before they occur.
Solution Approach 2:
The system implements feedback by transmitting prompt signals from the control module to the terminal device or barrier gate based on the verification result. When the battery verification succeeds, the system provides feedback to allow the vehicle to leave; when verification fails, feedback prevents the vehicle from leaving, ensuring reliable battery swapping monitoring.
2Reliability
If wireless communication verification is implemented, then unauthorized swaps are prevented, but the swapping process time increases
Solution Approach 1:
The system replaces mechanical or manual verification methods with wireless communication technology. The control module establishes wireless communication connection with the target battery management unit to automatically verify battery identification information, replacing manual checking processes and reducing the time required for verification while maintaining reliability.
3Reliability
If battery identification monitoring is added, then mistaken swaps are prevented, but the system complexity increases
Solution Approach 1:
The system uses the battery management unit as an intermediary that stores and provides battery identification information. The control module communicates with this intermediary to verify whether the target battery matches the vehicle requirements, simplifying the monitoring system architecture while effectively preventing mistaken swaps.

AI summary
Embodiments of the present application provide a vehicle control method, module, and system, a device and a medium. The method includes: acquiring, under a condition that it is determined to install a target battery provided by a battery swapping station for the vehicle, a network address of a first battery management unit of the target battery; requesting to establish a wireless communication connection between a control module and the first battery management unit, based on the network address of the first battery management unit of the target battery; transmitting, under a condition that the wireless communication connection between the control module and the first battery management unit is successfully established, a first prompt signal to a target object, where the first prompt signal is used to prompt the target object to perform a relevant operation for allowing the vehicle to leave a battery swapping area.
