– If a battery module is improperly treated, for example, burnt, needle-
pricked, squeezed, overcharged, or subject to other adverse conditions
that may cause battery thermal runaway, the battery may be damaged or
an abnormal chemical reaction may occur inside the battery, resulting in
electrolyte leakage or production of gases such as CO
To prevent fire or corrosion, ensure that flammable gas (such as
hydrogen) is properly exhausted.
Lead-acid battery:
Lead-acid batteries in use emit flammable gas. Ensure that batteries are kept
in a well-ventilated area and take preventive measures against fire.
NO TICE
● Do not use unsealed lead-acid batteries.
● To prevent fire or corrosion, ensure that flammable gas (such as hydrogen)
is properly exhausted for lead-acid batteries.
The battery room must not be located in environments where explosive gases
may exist or released.
The battery room must not be located near or under areas with water
leakage risks, such as water reservoirs, water landscapes, and water towers.
It is recommended that an independent battery room be used. If the total
battery capacity exceeds 600 kWh (for example, more than seven cabinets
each with a battery capacity of 80 kWh are deployed), an independent
battery room must be used.
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.
Combustible materials should not be stored in the battery room and should
be at least 3 m away from it.
A battery room deployed outdoors should be at least 3.0 m away from the
following places: municipal red lines, 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 strength should be the same as that of the
partition wall.
The battery room should be equipped with fire extinguishers that use
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
