What it covers
The North American battery-level safety standard for stationary applications. It evaluates the battery itself — cells, modules, pack, and the management system that protects them — against electrical, mechanical and thermal abuse conditions. It is the component-level evidence that feeds the system-level UL 9540 listing.
