Essentials on Containerized BESS Fire Safety
Fire Risks of Energy Storage Containers Lithium batteries (e.g., LiFePO4, NMC) may experience thermal runaway under conditions such as overcharging, short-circuiting, mechanical
4 FAQs about Fire safety distance for energy storage battery compartment
What are the requirements for a battery storage system?
If prefabs and containers are used -with a maximum area of 18.6 m 2 - the compartment must have a radiant energy detector system, a 2 h fire tolerance rating, and an automatic fire suppression system . If metal drums are used, vermiculite can be used to isolate the batteries from each other.
How far should lithium ion batteries be kept?
Lithium-ion batteries and cells must be kept at least 3 m from the exits of the space they are kept in . If prefabs and containers are used -with a maximum area of 18.6 m 2 - the compartment must have a radiant energy detector system, a 2 h fire tolerance rating, and an automatic fire suppression system .
Are battery energy storage systems safe?
Owners of energy storage need to be sure that they can deploy systems safely. Over a recent 18-month period ending in early 2020, over two dozen large-scale battery energy storage sites around the world had experienced failures that resulted in destructive fires. In total, more than 180 MWh were involved in the fires.
How to protect a battery from a fire?
Used and damaged batteries should not be kept in rooms or areas larger than 18.6 m 2 . A fire barrier with a fire-resistance rating of 2 h should be utilized to separate rooms or storage spaces from the rest of the building structure . A radiant energy detector and an automatic sprinkler system are required to protect the compartment .
