Revolutionise Battery Safety with the Li-ion Tamer GEN 3 Lithium Ion Battery Off-Gas Detection System

The Li-ion Tamer GEN 3 device detects the venting of battery electrolyte solvent vapors (off-gassing phase) that occur early in the failure mode of lithium-ion batteries.

Early detection of battery electrolyte vapours allows for proper mitigation steps to be taken to avoid a catastrophic thermal runaway failure.

The Li-ion Tamer GEN 3 system consists of several components, including sensors, a hub, a power switch, a network switch, and a controller.

The sensing nodes in the Li-ion Tamer GEN 3 system include off-gas sensors with advanced algorithms for detecting battery electrolyte vapors. They do not require calibration, are compatible with all lithium-ion battery form factors and chemistries, and have a lifetime comparable to a typical lithium-ion battery system. The sensing nodes also include temperature and humidity sensors for environmental monitoring.

The sensing nodes are networked by the hubs and switches to the controller, which serves as the central point for managing and monitoring the entire system.

The controller of the Li-ion Tamer GEN 3 system has relays and Modbus TCP/IP outputs that can connect to the Battery Management System (BMS) or other control systems.

The system configuration of the Li-ion Tamer GEN 3 system typically includes monitoring sensors installed at the battery racks to monitor off-gas events, reference sensors to monitor the ambient environment and air inlets, hubs installed in respective sensor zones, and a controller and Ethernet switch for aggregating sensor signals. Optional Power over Ethernet (PoE) switches can also be used for distributing power to the system.

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

It is important to note that the Li-ion Tamer GEN 3 device detects the venting of electrolyte vapors from lithium-ion batteries but does not prevent fires or thermal runaway. It is not a standalone safety device and should be incorporated into a proper safety system. If the device responds, there is a risk of a battery fault that could lead to thermal runaway, and immediate evacuation from the area is advised to avoid injury.
