Fire protection for lithium-ion battery storage systems

siemens fire safety application li-ion battery energy storage protection

Our energy infrastructure is undergoing a radical transformation. An influx of excess energy from renewable sources like wind and solar is causing fluctuations in energy supply and putting grid stability at risk. Energy storage is a key component to balance out supply and demand and absorb the fluctuations. Today, lithium-ion battery storage systems are the most common and effective type and, as a result, installations are growing fast.

Overview

Fire protection for lithium-ion battery storage systems

Li-ion battery storage systems - A manageable fire risk

Lithium-ion storage facilities contain high-energy batteries combined with highly flammable electrolytes. In addition, they are prone to quick ignition and explosion in a worst-case scenario. Such fires can have a significant financial impact on organizations. Rapid detection of electrolyte gas particles and extinguishing are the key to a successful fire protection concept. Since December 2019, Siemens has been offering a VdS-certified fire protection concept for stationary Li-ion battery storage systems.

Our Solution

Earliest possible detection with the FDA241 aspirating smoke detector

The FDA241 detects electrolyte vapor early and reliably thanks to its patented dual-wavelength optical detection technology. In accordance with normative requirements, two independent FDA241s are required to trigger the activation of the automated extinguishing system. The FDA241 is the ideal solution for early detection of electrical fires. In addition to controlling the automated extinguishing system, the fire protection system triggers all other necessary control functions.

Safe and sustainable fire suppression and extinguishing with Sinorix N2

Sinorix N2 extinguishing systems prevent electrical fires, stop the propagation of thermal runaways and reliably prevent the spread of secondary fires. A holding time of 30 minutes not only gives the fire brigade time to react, but also prevents any delayed runaway.

*Our tests have shown that the lower the remaining oxygen concentration, the better the protection against the explosive combustion of electrolyte vapor.
