The indoor layout of batteries should comply with local fire protection laws
and regulations in aspects such as production scenarios and the safe distance
and layout of buildings and materials.
Do not store combustible materials in the battery room. Keep such materials
at least 3 m away from the battery room.
A battery room deployed outdoors should be at least 3.0 m away from the
following places: restricted areas, combustible warehouses, dangerous goods,
high-stacking warehouses, power infrastructure, public roads, and buildings.
The battery room should be isolated from the adjacent area by fire
compartmentation. Holes should be sealed by firestop material. The fire
resistance and thermal insulation capabilities should be the same as that of
the partition wall.
The battery room should be equipped with fire extinguishers filled with
halogenatedane, heptafluoropropane, perfluorohexanone, carbon dioxide, or
dry powder. Each fire protection unit should be equipped with at least two fire
extinguishers, which should be checked and replaced periodically.
The battery room should be equipped with cabinet-level or room-level CO
sensors, smoke sensors, and temperature sensors. It is recommended that H
sensors and open flame sensors be deployed. At least two sensors of each
type should be deployed, and the automatic fire alarm system should be
enabled.
The battery room should be equipped with independent air conditioners and
ventilation ducts, which must be isolated from those for other equipment
areas or office areas. If ventilation ducts are shared, fire dampers must be
installed for the battery room. The ventilation and exhaust system must
interact with the fire alarm system and be able to handle flammable gases
with a concentration lower than 25% lower flammability limit (LFL).
The battery room should be equipped with a halogenatedane or
perfluorohexanone gas fire extinguishing system, which should interwork with
the fire alarm system. After the extinguishing agent is released, the battery
room should meet the requirement on flame extinguishing concentration
within 10 min.
The battery room should be equipped with fire extinguishing facilities such as
a dry-type water spray or water mist pipe network to cope with the risk of
reignition or fire spreading after the battery fire is extinguished.
The battery room should be equipped with pressure relief explosion-proof
devices or pressure relief channels (such as glass windows and magnetic lock
doors) with equivalent areas. According to the NFPA 68 or GB 50016
standard, if side pressure relief is adopted, a protective fence or wall should
be installed outside the pressure relief channels, and the fence or wall should
be at least 12 m away from the pressure relief wall.
The fire alarm system should interact with the ventilation and exhaust system
and automatic fire extinguishing system, able to trigger the energy storage
system to disconnect the charging and discharging circuits.
Fire alarms in the battery room should be automatically reported to the fire
supervision center. If the battery room is unattended, an automatic fire alarm
system must be deployed to report fire alarm signals to the remote
management center.
