Leak detection system for cable assembly
The granted patent (Publication Number: US11919411B2) discloses a leak detection system comprising a leak detection module with a power source generating an input voltage signal applied to a fluid at a first node. A controller monitors an output voltage signal to detect fluid leaks based on voltage drop thresholds. The system can operate in a self-check mode to simulate leaks and includes a test node for this purpose.
Furthermore, the leak detection system can trigger responsive actions upon detecting a leak, such as changing the charging status of an electric vehicle or alerting a user. The system includes switches at a second node to simulate leaks and can detect leaks based on peak-to-peak or maximum voltage drops. The module can operate in normal and self-check modes, with the self-check mode simulating leaks for testing purposes. The system is designed to be located within a cable for efficient leak detection and response, enhancing safety and reliability in various applications.
