Battery container fire and explosion in Vastra Frolunda, Gothenburg

A fire broke out in a battery storage container holding around nine tonnes of lithium batteries in the Sisjon industrial area of Vastra Frolunda, Gothenburg. The container, which was on wheels, was moved from indoors to outdoors after smoke was detected. Firefighters used a cutting extinguisher to cool the battery pack, but several minutes later an explosion occurred. A nearby building sustained some damage in the early stages of the fire and was evacuated as a precaution. Police issued a public warning (VMA) due to hazardous smoke, and residents in the area were told to stay indoors. One person was taken to hospital by ambulance due to breathing difficulties. Firefighting continued overnight. The following day, the batteries began smoking again, and the container was eventually submerged in water inside a larger container using a crane.

The source reports the fire originated in a container of lithium batteries (NMC chemistry) and that an explosion occurred after initial cooling efforts; no specific root cause or ignition source was confirmed in the reporting, and police stated a technical investigation would follow.

1. Moving a smoking battery container away from buildings can help limit fire spread but carries a risk of explosion during the process, so exclusion zones should be maintained.
2. Reignition can occur a day or more after apparent extinguishment, so extended monitoring and secondary response plans are needed.
3. Public warning systems and evacuation protocols for nearby buildings should be integrated into emergency response plans for battery storage sites, especially those located near industrial or residential areas.
