The BES Series Battery Safety Electrolyte Sensor from Honeywell brings early-stage detection to battery management. Designed to identify electrolyte vapor leaks during first-vent events, it allows for faster fault response to prevent thermal runaway. Utilizing an advanced and patented rate-of-change algorithm, the BES detects battery electrolyte vapor, as well as hydrogen and carbon monoxide gases released during a thermal runaway event. Optimized for 12V and 24V systems, these sensors simplify integration into electric vehicles (EVs), hybrids, battery energy storage systems (BESS), and industrial batteries. With its robust design and reliable performance, the BES series is an essential component for improving safety and monitoring in automotive applications.
