With the significant increase of the Electric Vehicles (EV) in the automotive market, the safety standards and regulations for these kinds of products are becoming more restrictive. One of the new problems for the EV is the Thermal Runaway (TR) event management. When this unwanted phenomenon happens, the uncontrolled rise of the temperature in one cell it can spread to the entire pack. The consequence of this chain reaction is the generation of a huge quantity of heat with flames and gasses venting which is very dangerous for the vehicle occupants. To make the Electric Vehicle safer, the Chinese legislation of 2018 establishes that the flame should not penetrate inside the passenger compartment earlier than 5 minutes after the onset of the Thermal Runaway.
