Product Overview
The SGX-BLD1 is an automotive-grade Hydrogen and Battery Leakage Detection sensor designed to monitor H2 concentration via CAN communication. It is crucial for ensuring the safe operation of hydrogen storage systems and Li-ion battery enclosures by detecting hydrogen gas generated during leakages or Li-ion battery Thermal Runaway failure modes. The sensor provides early warning signals to Vehicle Management Systems or Battery Management Systems, enabling timely alerts for passengers to evacuate. Its advanced thermal conductivity technology offers high reliability and a fast response time, making it an essential component for passenger safety in electric and hydrogen-powered vehicles.
