Codes & Standards for ESS & Repurposed Batteries
» UL 9540
- Standard for Energy Storage Systems and Equipment
- NEC 2017
» UL 9540A
- Test Method for Evaluating Thermal Runaway Fire Propagation in
Battery Energy Storage Systems
- IFC 2018 and NFPA 855
» UL 1974
- Standard for Evaluation for Repurposing Batteries
SLIDE 5
Why worry about Energy Storage System safety?
» Mitsubishi Materials Corporation (Japan 2011)
- 2 MW Sodium Sulfur system, thermal
runaway
» Kahuku Wind Farm (USA, 2012)
- 15 MW, Advanced lead acid battery
» The Landing Mall (USA, 2013)
- 50 kW Li-ion ESS system in a shopping
mall, thermal runaway
» Boeing 787 Dreamliner (USA, 2013)
- Li-ion battery, thermal runaway
» Engie Electrabel (Belgium, 2017)
- 20 MW Li-ion facility, thermal
runaway

Scope
- Safety standard for Energy
Storage Systems intended for connection to a local or utility grid or for a standalone application
- Intended for electrochemical,
chemical, mechanical and thermal types
UL 1973 + UL 1741 = UL 9540

Scope
- Covers the sorting and grading process of battery
cells, packs and modules that were originally configured and used for other purposes and that are intended for a repurposed use application
- The process of sorting and grading devices
- Determining the state of health and other
parameters to identify continued viability
- Rating mechanisms the manufacturer may use
for those that are determined suitable for continued use
