The Battery Safety Electrolyte Sensor (BES) is an automotive-grade sensor designed for early detection of venting and thermal runaway in battery systems. Utilizing an advanced and patented rate-of-change algorithm, the BES detects battery electrolyte vapor commonly released during the initial venting phase called First Vent, as well as hydrogen and carbon monoxide gases released during a thermal runaway event.
The ability to detect the First Vent provides an essential early warning for potential thermal runaway incidents in Lithium-Ion battery packs. This proactive early detection facilitates timely and appropriate mitigation measures, significantly reducing the risk of thermal runaway. BES employs a patented advanced rate of change algorithm designed to identify significant changes in the concentration of target gases within a sealed battery pack. This innovative method effectively reduces the occurrence of false negatives that may be seen with conventional ppm-based sensors, which focus on precise target gas threshold monitoring. The algorithm is tuned to prevent false positives, improving the end-user experience. Furthermore, the algorithm is supported by more than 12 years of rigorous research and validated through seven years of practical field deployment.
This extensive experience not only enhances the reliability of the detection algorithm but also underscores its effectiveness in real-world applications. BES enhances the safety and reliability of automotive battery systems.
