Analisi di rischio per i fenomeni di fuga termica nei veicoli elettrici in spazi confinati (gallerie stradali) = Risk analysis of thermal runaway of electric vehicles in closed spaces

This thesis presents a risk analysis of thermal runaway of electric vehicles in closed spaces. The use of electric vehicles has increased significantly in recent years due to their environmental benefits. However, the lithium-ion batteries used in these vehicles have the potential to cause thermal runaway, resulting in fires that can be difficult to extinguish. This risk is amplified when electric vehicles are stored or charged in closed spaces, such as underground parking garages or warehouses. This thesis investigates the potential risk of thermal runaway events occurring in electric vehicles (EVs) in closed spaces, such as garages or tunnels. Thermal runaway is a phenomenon where the battery cells in an EV rapidly heat up and release flammable gases, leading to a self-sustaining fire. The objective of this research is to provide a comprehensive risk analysis of thermal runaway events in closed spaces, considering various factors such as battery chemistry, charging behaviour, and environmental conditions. The results of this study provide insights into the potential risk of thermal runaway events in closed spaces, and the effectiveness of different mitigation strategies. The findings can be used to inform the development of safety guidelines and regulations for the use of EVs in closed spaces, as well as to guide the design of EVs and associated charging infrastructure to minimize the risk of thermal runaway events.
