With extreme weather events occurring more frequently, outdoor Battery Energy Storage Systems (BESS) face growing risks of flooding. Once floodwater enters the battery enclosure, it may lead to:
- Cell short-circuiting
- Triggering thermal runaway
- Battery module explosion
- Power outages and grid instability
- Threats to personnel safety and nearby facilities
These risks make flood protection an essential part of BESS engineering.
FM 2510 International Flood Protection Certification (ANSI/FM Approvals 2510-2020)
The flood door has passed the core FM tests, including:
Hydrostatic Pressure Test
- Simulates long-duration flooding and external water pressure to verify overall sealing performance.
- Ensures extremely low leakage rates to prevent water ingress into battery compartments.
Impact Test
- Simulates floating debris striking the barrier with a fixed energy level to verify structural strength and anchoring reliability.
- Ensures the system remains functional under strong water flow and debris impact.
FM 2510 is the world’s only international standard that conducts complete, system-level testing for flood protection products, and is widely recognized by BESS owners, insurers, and third-party regulatory authorities.
