Test method for safety and performance of thermal barriers for use in batteries and battery based energy storage systems
Scope:
Note: The scope for this NOI (originally published on February 23, 2021) was updated by the responsible SDO on May 14, 2024.
1.1.
This standard provides requirements to properly assess the thermal and mechanical performance of thermal barriers used between cells in battery pack and battery system.
1.2.
The purpose of this standard is to provide testing requirements for thermal barriers used in battery pack and battery system intended to limit the propagation of thermal runaway.
1.3.
This standard provides criteria to categorize thermal barriers based on their performance.
1.4.
Thermal barrier material's property when tested according to this standard may vary based on its use in a battery and battery systems. Test results of this material property will provide thermal barrier property details for comparison with different materials. Testing for propagation of thermal runaway to be conducted to meet the end product requirement.
Project need:
Currently the focus of safety related standard for battery energy storage is on evaluation of the fire safety through evaluating thermal runaway fire propagation. Recent advances in developing special thermal barrier materials and design required dedicated testing method to evaluate safety and performance of these materials for their specific application. Since these design changes make it difficult to initiate thermal runaway, additional testing methods must be used to further investigate safety and performance.
