Fire tests 2025 in spain
The highlight of the project was the fire tests conducted in October and December 2025. The fire behaviour of lithium-ion batteries was investigated on a scale that is unique worldwide to date.
Existing regulatory requirements for lithium-ion batteries have so far focused only to a limited extent on aspects of battery storage. Battery storage plays a crucial role, for example, in the context of installation in vehicles or recycling. The resulting risks differ significantly from those of conventional fires. Assessing the risks and developing measures to mitigate them requires conducting fire tests such as these.
To implement the project, a rack storage facility for lithium-ion batteries was replicated and fully functional battery modules were stored on pallets. A high-pressure water mist system from FOGTEC was used as part of the firefighting tests. The aim was to prevent the flames from propagating further.
Various measuring instruments were used to determine the fire behavior. The developing temperatures were measured using thermocouples. In addition, optical and infrared cameras were used. The combination of these methods allows for a precise analysis of the fire progression and temperature development. In the event of a battery fire, gases are produced whose properties differ from those of ordinary fire loads. The gas components were determined using various gas measuring devices, including an FTIR.
The goal of limiting the further spread of the fire to the initial shelf compartment by using a firefighting system was fully achieved.The high-pressure water mist system proved highly effective and prevented the fire from spreading.
The data and insights gained are now being used to increase safety in this area. In this context, recommendations are currently being developed, which will then be published and presented to various committees.
