Energy storage battery American standard

What is a battery energy storage system?

Battery energy storage systems (BESS) stabilize the electrical grid, ensuring a steady flow of power to homes and businesses regardless of fluctuations from varied energy sources or other disruptions. However, fires at some BESS installations have caused concern in communities considering BESS as a method to support their grids.

Do energy storage systems need to be certified?

U.S. fire and electrical codes require that energy storage systems be listed, meaning the product must be tested by a Nationally Recognized Testing Laboratory (a private-sector organization recognized by the Occupational Safety and Health Administration) and certified to meet consensus-based test standards.

What is the UL 9540 standard for energy storage systems?

For ESS, the standard is UL 9540, Standard for Energy Storage Systems and Equipment. UL 9540 covers the complete ESS, including batery system, power conversion system (PCS), and energy storage man-agement system (ESMS). Each of these components must be qualified to its own standard:

Are batteries the future of energy storage?

Batteries now support efforts to ensure low-cost, domestic energy production. At the U.S. Department of Energy’s (DOE) Argonne National Laboratory, researchers are advancing breakthroughs at every stage in the energy storage lifecycle.

What is a quali-fication standard for ESS bateries?

For example, the quali-fication standard for ESS bateries, UL 1973, Standard for Bateries for Use in Stationary and Motive Auxiliary Power Applications (see Section 3.4), started life in 2013 with the title, ‘Bateries for Use in Light Electric Rail (LER) Applica-tions and Stationary Applications.’

What types of bat-Tery systems are available?

Additional guidance is provided for certain classes of bat-tery systems in a series of subsidiary documents. Published guides are for lithium-based bateries (IEEE Std 1679.1), sodium-beta bateries (IEEE Std 1679.2), and projects are underway for flow bateries (P1679.3) and alkaline and zinc-based technologies (P1679.4).
