Brief: In recent years, the United States has led the world in the installation and usage of energy storage systems. At the same time, there have been serious fires in the energy storage systems in various states, one of the causes of these events is the thermal runaway of the cell inside the energy storage system. Therefore, state governments are paying more and more attention to the fire safety of energy storage systems, and the UL9540A is a test method to evaluate the spread of large-scale thermal runaway fire of battery energy storage systems. The standard became a national standard in both the United States and Canada in 2019.
DEFINITION OF BATTERY ENERGY STORAGE SYSTEM (BESS)
Stationary equipment that receives electrical energy and then utilizes batteries to store that energy to supply electrical energy at some future time. The BESS, at a minimum consists of one or more modules, a power conditioning system (PCS), battery management system (BMS) and balance of plant components.
Common energy storage systems: photovoltaic energy storage systems, wind farm energy storage systems
REGULATORY FRAMEWORK & TECHNICAL REQUIREMENTS:
Tests are performed at cell level, module level, unit (cabinet) level, and installation level
Cell Level | Module Level | Unit Level | Installation Level | |
Testitems | Thermal runaway test | Thermal runaway test | Thermal runaway test | Thermal runaway test |
Purpose | To determine the thermal runaway method and characteristics of the cell, and to collect and analyze the exhaust of the cell. | To verify the extent of thermal runaway spread in the module | To measure temperature and heat flux in the target unit and surrounding walls. | To evaluate the effectiveness of fire protectionsystem. |
