Vesda Xtralis LT-SEN-R3 Li-ion Tamer Sensor Reference LT Gen 3

The Li-Ion Tamer Reference Sensors are indicated by blue endplates and are mounted near external contaminant entry points to prevent false-positive alarms.

The Li-ion Tamer GEN 3 is a device that detects the venting of battery electrolyte solvent vapours (off-gassing phase) that occurs early in the failure mode of lithium ion batteries (LIB). The early detection of this event allows proper mitigation steps to be taken to avoid a catastrophic thermal runaway failure.

Each sensing node comprises an off-gas sensor with advanced algorithms making it acutely sensitive to detecting battery electrolyte vapours (off-gassing compounds), does not require calibration, is compatible with all LIB form factors and chemistries, and has a lifetime comparable to a typical LIB system. The sensing node also includes temperature and humidity sensors for environmental monitoring.

Sensing nodes are networked by the hubs and switches to the controller, which is the central point for managing and monitoring the entire system. The controller has relays and Modbus TCP/IP outputs that connect to the BMS or other control systems.

The Li-ion Tamer GEN 3 system requires minimal operation and maintenance procedures as the sensors are calibration-free and have comparable lifetime to that of the ESS battery system. The gas sensors response can be easily verified with a simple test. To confirm operation, sensors can be activated with a bottle of battery off-gassing compounds (Diethyl Carbonate, DEC) which is supplied by Xtralis.
