On June 28th 2023, the standard for energy storage battery system ANSI/CAN/UL 9540:2023：Standard for Energy Storage Systems and Equipment issues the third revision. We will analyze the differences in definition, structure and testing.Add definition of AC ESS
Add definition of DC ESS
Add definition of Dwelling Unit
Add definition of Energy Storage Management System (ESMS)
Add definition of External Warning Communication System (EWCS)
Add definition of Flywheel
Add definition of Habitable Space
Add definition of Remote Software Update
For Battery Energy Storage System (BESS), the enclosure should meet UL 9540A Unit Level testing.
Gasket and seals can comply with UL 50E/CSA C22.2 No. 94.2 or comply with UL 157 or ASTM D412
If BESS uses metallic enclosure, that enclosure should be noncombustible materials or comply with UL 9540A unit.
ESS enclosure should have certain strengthen and rigidity. This can be proved by passing test of UL 50, UL 1741, IEC 62477-1, UL 2755, ISO 1496-1 or other standards alike. But for ESS less than 50kWh, the strengthen of enclosure can be evaluated through this standard.
