Battery detectors prevent thermal runaway

Technology

BES LITE, available in flange and board mount versions, is designed to detect gases typically released in the initial phase of a thermal runaway as well as throughout the thermal runaway. This advanced detection capability enables the rapid identification of imminent hazards or risks, significantly improving safety measures in critical situations. Therefore, the sensor enables the activation of mitigation measures that can prevent the loss of assets and protect lives.

Customer benefit

Improved protection of systems through early detection of thermal events
Reduces false alarms through selective reaction to electrolyte vapors
Reliable in critical environments as it is insensitive to cross interference gases and siloxane poisoning
Easy installation in confined spaces thanks to flat design and mounting flanges (flange-mounted version) or mounting pins (PCB-mounted version); simple integration via three-stage analog output

Most important properties

Early detection: Detects venting events long before a thermal runaway occurs
Timely warning messages: Provides early warnings of impending thermal runaway
Selective sensitivity: selectively detects electrolyte vapors for high accuracy
Space-saving design: compact design can be seamlessly integrated into battery packs
Integrated diagnostics: Enabled by an analog three-stage output
