Battery Module Housing Opening Detection and Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The risk of operating an electric bicycle with a potentially dangerous battery module due to improper repairs or the use of unsuitable components, which can lead to damage and safety hazards.
Innovation Solution
A method for detecting an opening in the battery module's housing using multiple sensors to generate a locking signal that deactivates the battery management system, preventing normal operation, charging, or discharging, and featuring a reset mechanism to ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the housing is opened for repair or component replacement, then maintenance and replacement can be performed, but the risk of improper repair or use of unsuitable components increases
Solution Approach 1:
The patent applies preliminary action by detecting the opening of the housing before any repair or component replacement takes place. Sensors detect when the housing is opened and trigger the battery management system to store locking signals, preventing operation with potentially improper repairs. This proactive detection ensures that even if repair work is performed, the system can identify and prevent unsafe conditions before they lead to failures.
2Reliability
If the battery management system is deactivated by opening the housing, then safety is improved by preventing operation with damaged components, but the loss of information about the opening event occurs
Solution Approach 1:
The patent implements feedback by using sensors to detect when the housing is opened and providing this information back to the battery management system. The system stores locking signals that record the opening event and prevent further operation, while maintaining information about what occurred. This feedback loop ensures both safety through deactivation and preservation of diagnostic information about the housing opening and any subsequent repairs.

AI summary
A method for detecting an opening in the housing (250) of a battery module (100) comprising the steps of: acquiring (310) a first measurement by means of a first sensor (260), wherein the acquired first measurement represents a detected opening of the housing (250); generating (320) a first sensor signal by means of the first sensor (260) depending on the acquired first measurement; activating (330) a battery management system (200) depending on the first sensor signal; generating (340) a locking signal depending on the first sensor signal of the first sensor (260) by means of the battery management system (200); and deactivating (350) the battery management system (200) depending on the generated locking signal.
