Technical FAQs 4

What are the UL 9540 standards for energy storage systems?

The following are the most widely recognized benchmarks for system-level safety. UL 9540 is the comprehensive safety standard for energy storage systems (ESS), focusing on the interaction of system components. It evaluates the overall performance, safety features, and design of BESS, ensuring they operate effectively without compromising safety.

Are beyond-Li-ion energy storage technologies safe?

Safety and degradation of beyond-Li-ion technology: Many emerging energy storage technologies are presented as ‘safer’ alternatives to Li-ion systems. Full, rigorous FMEAs still need to be completed for these new technologies to understand their unique safety and degradation profiles.

What are the three pillars of energy storage safety?

A framework is provided for evaluating issues in emerging electrochemical energy storage technologies. The report concludes with the identification of priorities for advancement of the three pillars of energy storage safety: 1) science-based safety validation, 2) incident preparedness and response, 3) codes and standards.

What's new in energy storage safety?

Since the publication of the first Energy Storage Safety Strategic Plan in 2014, there have been introductions of new technologies, new use cases, and new codes, standards, regulations, and testing methods. Additionally, failures in deployed energy storage systems (ESS) have led to new emergency response best practices.
