The Chicago Fire Department recently released a public service announcement on lithium-ion battery safety, as they respond to an increasing number of fires caused by the batteries. The PSA warns against counterfeit batteries, improper charging, mixing battery types, aging batteries, and battery modifications.
But the Chicago Fire Department says it has seen a spike in the number of fires sparked by lithium batteries, and injuries that have resulted. Lithium-ion batteries can erupt in violent explosions and out-of-control fires, and toxic chemicals can be released rapidly.
Damaged, altered and uncertified lithium-ion batteries pose a growing threat to public safety, and this month the Chicago City Council voted to protect residents, first responders and city workers from the products that can cause uniquely dangerous fires.
In 2023, lithium-ion batteries were the leading cause of fires in New York City, with 268 related incidents that resulted in 18 deaths and 150 injuries. Recent reports from across the country include battery fires in planes, freight trains, cargo ships and intermodal shipping facilities.
To enhance the safety of lithium-ion batteries, manufacturers can employ several strategies: Battery Management Systems (BMS): Implementing advanced BMS in electric vehicles and energy storage systems can monitor battery conditions, including voltage, current, and temperature, to prevent overcharging and thermal runaway.
The CFD also warns of a danger if a lithium battery is leaking, bulging, or has a strange odor. Last year in New York City, 18 deaths were attributed to fires started by the batteries—which were a leading cause of fires. THE CFD said it recently began collecting similar data.
