Concerns regarding new risks of fires in electric vehicles (EVs) compared to internal combustion engine vehicles (ICEVs) have been raised lately. The concerns primarily relate to fires in enclosed spaces such as parking garages and road tunnels. Consequently, there are indications that some stakeholders want to prohibit EVs from underground parking garages. For the success of electromobility and the transition from fossil-to renewable-fuels, it is important to understand the risks and consequences of fires in EVs and provide technical solutions if necessary, so as not to hinder the widespread adoption. It is also vital that non-fact-based discriminatory treatment of EVs is prevented. This work has investigated the risks and consequences of fires in EVs with a focus on enclosed spaces such as parking garages and tunnels. The overall goal was to identify differences and similarities between fires in EVs and ICEVs and to propose measures to prevent and mitigate fires in enclosed spaces both at infrastructure and vehicle level. The conclusions and proposed measures have been based on all parts of the study, which included a literature study, a risk assessment based on hazard identification workshops (HAZID) as well as a workshop with personnel from fire and rescue services.
