Thermal Runaway Warning Based on Safety Management System of Lithium Iron Phosphate Battery for Energy Storage

Abstract

This paper studies a thermal runaway warning system for the safety management system of lithium iron phosphate battery for energy storage. The entire process of thermal runaway is analyzed and controlled according to the process, including temperature warnings, gas warnings, smoke and infrared warnings. Then, the problem of position and threshold setting of the warning sensors are studied. Finally, a hierarchical warning system is established and a communication architecture diagram of system warning is constructed. It is shown that the system can quickly locate the area where the battery pack is out of control, and quickly perform corresponding disconnection, firefighting and alarm operations to ensure the safe and stable operation of the battery storage power station.
