SafeBESS: Technology and building design for safe operation of battery energy storage systems
SafeBESS consortium meeting and workshop on November 18th and 19th 2024
The meeting was also this time organized as a hybrid meeting where most of the participants were physically present, while a few attended via Teams.

The first day of the meeting started with updates of the PhD work which is done in collaboration with the research partners on fire testing of battery cells and modules. Experimental work is done on both NMC-cells and LFP-cells. Module test were performed on batteries provided by Siemens Energy. Later in the day more detailed information on the work done with the development of the numerical models and simulations was provided. These models, when fully developed, should be able to simulate a battery fire and how it propagates in modules and packs. The models are developed based on the experimental data to ensure that the simulations are as close to reality as possible. It is therefore also important to discuss and plan the experiments thoroughly, in which the experience and feedback from the industry partners are vital. In 2025 new experiments are planned, where extinguishing of battery fires will be explored. For these experiments it will also be performed chemical analysis of the water used for extinguishing to investigate the type of chemicals washed away in a battery fire.
Parts of the work which is now done in SafeBESS was presented at the 4th European Symposium on Fire Safety Science which took place in Barcelona in October 2024. The conference paper can be found here:
Day 2 of the consortium meeting started with updates on work package 3, which focuses on construction of battery rooms. Here, initial simulation work on ventilation solutions for battery rooms was presented. The aim of this work is to investigate how different ventilation strategies will affect the fire. Following the presentation, a workshop on ventilation strategies and battery room construction was conducted. The results from this workshop will be utilized in the further work in SafeBESS.
Day 2 was finalized with the steering committee meeting where the work plan for 2025 was discussed.
