Jule Leads Industry in Fire Safety by Earning UL9540A Thermal Runaway Standard for its Energy Storage & EV Charging Systems

UL9540A is an internationally recognized industry benchmark specifically designed to assess the risks associated with energy storage systems during thermal runaway events—a critical concern tied to lithium-ion battery failures. Jule’s successful certification under this stringent standard not only validates the robustness of its FSS but also underscores the company’s dedication to pushing the boundaries of energy storage safety.

Exceptional Performance Above and Beyond

What distinguishes Jule is not only meeting the UL9540Astandard but exceeding its stringent requirements. Jule’s FSS is able to rapidly cool the initiating module, drastically reducing temperatures to safe levels in minutes. This level of thermal management is pivotal in preventing the escalation of thermal runaway events. Moreover, Jule’s Battery Module exhibited exceptional resilience during testing, with less than 14% of cells experiencing failure before the FSS successfully mitigated the thermal runaway event. This outcome underscores the robustness and reliability of Jule’s energy storage solution.

Real-World Implications

This has tangible real-world implications for safety and reliability. Rapidly cooling temperatures during thermal runaway events minimizers potential damage to the system and surrounding infrastructure, safeguarding investments and, most crucially, human lives. This means it also enables Jule’s Battery modules to be safely installed indoors and and enclosed locations such as underground parking lots.

A Commitment to Safety and Innovation

Jule’s Director of Mechanical Engineering, Omri Tayyara,Ph.D. commented, “Our dedication to safety extends beyond certifications and standards compliance. It is deeply ingrained in the company’s culture and engineering principles. The pivotal role of energy storage systems in modern society, from supporting renewable energy integration to enhancing grid stability, drives our commitment to pushing the boundaries of performance and safety.”
