Understanding the Fire Risk in BESS
Flammable Gases

Flammable Gases
Hydrogen (H₂) and volatile organic compounds (VOCs), along with other off-gasses, are released before a Thermal Runaway event. These flammable and hazardous gases increase the risk of fire and explosion. BESS manufacturers can implement digital solutions and real-time monitoring strategies that enhance their safety protocols.
Thermal Runaway
Flammable Gases
Flammable Gases
Lithium-ion cells may fail due to defects, aging, or electrical abuse. Overcharging, Overdischarging, Mechanical damage or Internal failure can initiate thermal runaway within the cell. Once thermal runaway begins, it triggers an exothermic chain reaction that is very difficult to control.
Electrical Fire

Electrical Fire
High-current terminations and PVC-insulated cables are common in BESS. It’s crucial to address issues like loose connections, aging insulation, and thermal stress, as these can lead to hot spots. If heat spreads to battery cells, it can trigger thermal runaway, a critical concern that impacts overall system performance.
