BES-131-111-001

BES-131-111-001 is a Battery Safety Electrolyte Sensor (BES). It 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.
