FIRE SAFETY PRODUCTS AND SYSTEMS protection for Battery Storage Systems performance battery storage brings an elevated risk for fire Our detection suppression technologies help you manage it with confidence protection for Lithium Ion Battery Energy Storage Systems energy infrastructure undergoing a radical overall demand for energy increases in our modern world so does the of renewable sources like wind and solar As the use of these variable of energy grows so does the use of energy storage systems Energy is a key component in balancing out supply and demand fluctuations lithium ion battery energy storage systems BESS have proven to be most effective type and as a result installations are growing fast lithium ion battery energy storage a manageable fire risk storage facilities contain high energy containing highly flammable electrolytes addition they are prone to quick ignition and explosions in a worst case scenario Such can have significant financial impact on and create a deadly hazard for those site Rapid detection of electrolyte gas particles extinguishing are the key to a successful fire concept Since December 2019 Siemens been offering a VdS certified fire detection for stationary lithium ion battery energy systems to the BESS application is early detection of pending event Early detection allows mitigation to be carried out long before a potentially event such as lithium ion battery runaway occurs By leveraging patented detection technology inside FDA241 device Siemens fire protection has the level of protection in modern day facilities Siemens research with multiple lithium ion manufacturers the FDA unit has proven to a pending battery fire event up to 5 times than competitive detection technologies translates into earlier transmission of danger to the resident battery management and fire systems These systems initiate mitigation such as battery charger battery and application specific actions such as activation 5 times faster detection capability Siemens detection products contribute to stationary battery energy storage systems a very manageable risk storage facilities high energy batteries highly flammable FDA241 has a VdS approval no S 619002 and performance verification as an early warning detection device for Lithium ion battery off gas detection VdS approval can be used to meet NFPA 855 requirements through equivalency allowance in NFPA 72 section 1.5 Currently there are no other global performance standards for the detection of Lithium ion battery off gas firealarmresources com protection for Lithium Ion Battery Energy Storage Systems possible detection the FDA241 aspirating smoke Particle OGP detector Solution smoke detectors continuously draw samples from the areas requiring protection evaluate them for the presence of particles of e g smoke etc They ensure reliable detection in demanding application areas earliest possible fire detection is essential business continuity is paramount FDA241 detects lithium ion electrolyte vapor known as lithium ion particles early reliably thanks to its patented dual wavelength detection technology The FDA241 is the solution for early detection of electrical fires addition to controlling the automated system the fire protection system all other necessary battery management control functions cabinet smoke and off gas detection systems its name implies aspirated smoke and off gas detection use an aspirator mounted in a detector unit The connects to a sample pipe network mounted within area or object being protected Using the suction from the air is continuously sampled and transported to the chamber for analysis for particles of combustion lithium ion electrolyte vapor battery cabinet protection the BESS application each sample pipe extends from the detector to monitor specific areas of interest It is key to the pipe sample holes where the smoke and off gas will appear This is largely dependent on battery geometry and HVAC airflow patterns which can be in each application The system designer should these factors as well as location of cabinet exhaust in each cabinet protection design layout firealarmresources com protection for Lithium Ion Battery Energy Storage Systems aspirated smoke and Particle detection patented smoke and particle detection technology which excels smoke and lithium ion battery off gas detection does ASD Particle OGP work a unique aspirator a portion of air is drawn the sample pipe network which mounted on lithium ion battery racks and passed into a chamber The detection chamber is designed to be highly sensitive to smoke off gas particles Typically aspirating smoke can be several hundred times more than traditional point type smoke detectors Siemens Aspirated Off Gas Particle detector uses a patented optical dual wavelength which combines blue and infrared light to discriminate between smoke particles dust steam particles and most importantly battery Particles air inlet of a pipe network bypass flow receiver power LED chamber airflow filter light zone flow light trap power LED chart above illustrates the aerodynamic design of the Siemens aspirated smoke and detection chamber A venturi is forcing only a small portion of air into the detection chamber Smoke and dust particles are detected by a highly optical measurement arrangement An optimized chamber airflow assures no separation of smoke and dust particles prevents surface contamination protection for Lithium Ion Battery Energy Storage Systems Salt Dust Dust Sand Ash Drops Size chart illustrates the array of particles found within an ambient These particles range from on the far left end smallest particles smaller than 0.001 microns to sand on far right largest particles larger than microns particulate matter depicted in the illustration above different types of particles fit within a range of sizes from small to large The blue and red curves graphically represent the distribution across the range of particle sizes demonstrating how the particles detected using dual wavelength technology various particle types can be categorized as large particles greater than 1 micron detected by infrared light scattering and small particles less than 1 micron smoke that are effectively detected by blue light scattering In the patented detection chamber the red and blue light scatter signals are accurately using precision algorithms to detect by products of fire and lithium ion off gas particles These same algorithms reject the effects of deceptive providing resistance to unwanted alarm conditions not found in other detection technologies is important to note that Siemens patented dual wavelength technology is not a detector It leverages infrared and blue light energy to accurately perform particle Targeted lithium ion off gas particles are not pure gases they are by products overheated lithium ion electrolytes These vaporized electrolyte particles fall within blue region making it easily detectable by the FDA241 unit these facts add up to increased value in Siemens FDA smoke and lithium ion off gas technology providing 5 times faster detection for the safety of lithium ion energy storage systems
