6 Frequently Asked Questions about “Energy storage equipment related standards”

What is the energy storage standard?

The Standard covers a comprehensive review of energy storage systems, covering charging and discharging, protection, control, communication between devices, fluids movement and other aspects.

What if the energy storage system and component standards are not identified?

Table 3.1. Energy Storage System and Component Standards 2. If relevant testing standards are not identified, it is possible they are under development by an SDO or by a third-party testing entity that plans to use them to conduct tests until a formal standard has been developed and approved by an SDO.

Do energy storage systems need a CSR?

Until existing model codes and standards are updated or new ones developed and then adopted, one seeking to deploy energy storage technologies or needing to verify an installation's safety may be challenged in applying current CSRs to an energy storage system (ESS).

Do electric energy storage systems need to be tested?

It is recognized that electric energy storage equipment or systems can be a single device providing all required functions or an assembly of components, each having limited functions. Components having limited functions shall be tested for those functions in accordance with this standard.

Does ul test large energy storage systems?

Research offerings include: UL can test your large energy storage systems (ESS) based on UL 9540 and provide ESS certification to help identify the safety and performance of your system.

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.
