UL 9540 Second Edition: Understanding the Impacts of Requirement Changes

Over the past several years, a significant effort has been made to address energy storage system (ESS) safety, especially those systems that use batteries as their source of energy. New technologies are now widely deployed in an already established infrastructure. While innovative, these technologies do not come with a long-standing history of use in our current infrastructure. This can cause concern from regulators, fire marshals, electrical inspectors, building owners and other industry stakeholders about the safety of these systems and how to best integrate them into facilities.

The second edition of UL 9540 incorporates both revised requirements and new requirements, all of which will impact multiple stakeholders differently. In the rapidly growing ESS market, key stakeholders may not have sufficient time or resources to review every proposal for changes and understand how the proposed changes could impact their ESS products or their business.
