Standard requirements for energy storage lithium batteries

What is a battery energy storage system (BESS)?

The solution lies in alternative energy sources like battery energy storage systems (BESS). Battery energy storage is an evolving market, continually adapting and innovating in response to a changing energy landscape and technological advancements.

Does a lithium battery chemistry affect the ESS code threshold?

While it is essential to consider the specific lithium battery chemistry, note that it does not impact this code threshold. IFC 1207.3 requires third-party listings for ESS. The ESS must be listed in accordance with UL 9540, the Standard for Safety of Energy Storage Systems and Equipment.

Are battery energy storage systems safe?

Battery Energy Storage Systems are vital to modern energy infrastructure. However, they introduce various safety challenges that require attention. Mitigating these risks is essential to ensure the reliability, efficiency, and safety of these systems. Thermal runaway is one of the most serious risks in BESS.

What is the hazard threshold for lithium battery chemistry?

Despite the six leading battery chemistry types having varying hazard performances, the code applies a uniform 20 kilowatt-hours (kWh) threshold for compliance. While it is essential to consider the specific lithium battery chemistry, note that it does not impact this code threshold. IFC 1207.3 requires third-party listings for ESS.

Are fire protection requirements not related to battery energy storage system equipment covered?

1.3 Fire protection requirements not related to battery energy storage system equipment are covered by appropriate installation codes. 1.4 See Figure 1.1 for a schematic of the test sequence in this document. See Appendix a which explains: c) Interpretation and application of the results.

Does ul 9540a certify a battery energy storage system?

UL 9540A does not certify products. Instead, it offers important data for designing safer battery energy storage systems (BESS). It also helps with following installation codes like NFPA 855. NFPA 855 is the guideline for installing Battery Energy Storage Systems (BESS).
