Traditional methods like water may be ineffective and can even exacerbate the situation by causing short circuits. Specialized extinguishing agents, such as those designed for lithium-ion batteries, are recommended. These agents work by cooling the battery and suppressing the chemical reactions that fuel the fire. Research from the National Renewable Energy Laboratory (NREL) highlights the effectiveness of various extinguishing agents in controlling EV battery fires.

• Cooling and Monitoring: Once the fire is suppressed, it’s essential to continuously cool the battery to prevent reignition. This can be achieved by applying water or other cooling agents directly to the battery pack. Monitoring the battery’s temperature is also crucial, as reignition can occur hours or even days after the initial fire. Thermal imaging cameras can be used to detect hotspots and ensure that the battery is adequately cooled. The Electric Power Research Institute (EPRI) offers resources on post-fire management of EV batteries.

• Safe Disposal: After the fire is extinguished and the battery is cooled, it must be safely disposed of to prevent environmental contamination. Damaged lithium-ion batteries can release hazardous materials, so it’s essential to follow proper handling and disposal procedures. This typically involves transporting the battery to a specialized recycling facility that can safely dismantle and recycle the components. The Environmental Protection Agency (EPA) provides guidance on the proper disposal of EV batteries.
