6 FAQs about [Energy storage safety standard 9540]

What does ul 9540 mean for energy storage systems & equipment?

The third edition of the UL 9540 Standard for Safety for Energy Storage Systems and Equipment, published in April 2023, introduces replacements, revisions and additions to the requirements for system deployment.

What is an ESS ul 9540?

15.2 Equipment Listings. ESS shall be listed and labeled in accordance with UL 9540. The standard defines electrical, mechanical, fluid containment, environmental performance, and system safety tests for energy storage systems. Note that this is a system-level standard, meaning that all components that make up an ESS must be tested together.

What are energy storage requirements?

1.1 These requirements cover an energy storage system (ESS) that is intended to receive and store energy in some form so that the ESS can provide electrical energy to loads or to the local/area electric power system (EPS) when needed. Electrochemical, chemical, mechanical, and thermal ESS are covered by this Standard.

Do electrochemical ESSs need to be ul 9540?

These codes and standards have one thing in common: they all require electrochemical ESSs to be listed in accordance with UL 9540, the Standard for Safety of Energy Storage Systems and Equipment, which was first introduced in November 2016.

What is STP 9540?

In 2015, STP 9540 was established as the consensus body responsible for UL 9540, the Standard for Safety for Energy Storage Systems and Equipment. It was initially comprised of 28 voting members.

Does an energy storage system need to be UL listed?

If an ESS were comprised of a battery (listed to its component-level standard, UL 1973) and a battery inverter (listed to yet another standard, UL 1741) packaged and designed to work together as an energy storage system, they must be tested and listed as such. This ensures that safety is retained at an integrated system level.
