Battery Fire Protection

How do you prevent lithium-Ion batteries from catching on fire?

Lithium-ion batteries offer high energy density in a small space. That makes them highly suitable for stationary electrical energy storage systems, which, in the wake of the energy transition, are being installed in more and more buildings and infrastructure projects around the world. They deliver large amounts of power within a very short response time.

Lithium-Ion fire risk prevention systems have been designed to prevent thermal runaway in industrial Lithium-Ion Battery Energy Storage Systems (BESS).

One of the early warning signs of a problem is the production of off-gases, and if detected early enough can allow actions to be taken that may prevent such a catastrophic event.

The Lithium-Ion Risk Prevention System is designed to monitor the batteries and detect these off-gases/toxic vapors in order to provide an early warning detection.

There are two Lithium-Ion Risk Prevention Monitoring Sensors used in the system:

A reference sensor and a monitoring sensor.

The reference sensor provides surrounding ambient air data to the controller, while the monitoring sensor is placed within the battery racks or racking system to allow for capturing data relating to the air directly adjacent to the Lithium-Ion batteries. The controller is constantly monitoring both the ambient environment and battery rack air for changes of less than 1 ppm of Lithium-Ion off-gas compounds.

The system is seeking to detect the presence of off-gases, indicating the early stages of battery cell malfunction prior to thermal runaway.

The system will communicate with the battery management system, to shut down the failing batteries and, when combined with the fire detection and Inergen® or SAPPHIRE Fire Suppression Systems, may activate the suppression system to mitigate off-gas ignition and inert the area, while providing local and remote alarms to inform personnel and emergency response teams

The Li-ion Tamer Rack Monitor system requires minimal operation and maintenance procedures as the sensors are designed to be calibration-free and have comparable lifetime to that of the ESS battery system.
