UL 9540A Test Method for Battery Energy
The UL 9540A test method is designed to meet stringent fire safety and building code requirements for battery energy storage systems.
A Battery Energy Storage System container is more than a metal shell—it is a frontline safety barrier that shields high-value batteries, power-conversion gear and auxiliary electronics from mechanical shock, fire risk and harsh climates.
Two more battery energy system storage (BESS) providers, including a manufacturer, have detailed successful fire testing.
1. Objective Lithium-ion battery (LIB) energy storage systems (ESS) are an essential component of a sustainable and resilient modern electrical grid. ESS allow for power stability during increasing strain on the grid and a global push toward an increased reliance on intermittent renewable energy sources.
Our Battery Labs have shock and vibration testing systems with a maximum force vector of 120 kN, mounting surfaces of 1.20 x 1.20 m and a maximum load of up to 1,000 kg. Shaker tests are also possible under thermal and climatic superposition with simultaneous loading/unloading.
Our large battery test channels provide voltages up to 1,000 V at maximum powers of 540 kW. Our Battery Labs have shock and vibration testing systems with a maximum force vector of 120 kN, mounting surfaces of 1.20 x 1.20 m and a maximum load of up to 1,000 kg.
These announcements follow a broader trend among battery storage manufacturers to publicly demonstrate safety performance under extreme conditions. In February, Huawei reported that its grid-forming BESS platform delayed fire ignition for seven hours during “extreme” thermal runaway testing, even as the number of failing cells increased.
