The battery is one of the core factors for the market success of battery electric vehicles (BEV). After mechanical, thermal or electrical abuse, a battery cell can go into thermal runaway. This leads to the rapid emission of hot, combustible gases caused by exothermic reactions of reactive components. Due to the high energy released, solid material from the damaged interior of the battery cell is ejected as particles together with the gas. The hot gas-particle mixture poses a high risk to all surrounding systems and can ignite in the worst case.
In our webinar, Matteo Fritz gives an insight into how the modeling of the battery thermal runaway including the ejected particles in our CFD software simulation tool AVL FIRE™ M looks in detail and what the challenges and criteria for evaluating the risk of ignition are in such a simulation.
Key topics and takeaways:
• 3D thermal runaway simulation
• Particle modeling
• Evaluation of the ignition hazard emanating from particles and gases
In the development of battery electric vehicles (BEVs), safety plays an essential role alongside range and service life, determining customer acceptance and approval. Especially due to ever increasing energy densities, passive safety in case of fire has turned out to be a major challenge for almost all OEMs.
Thermal design is an important component in the battery development process, since temperature has a strong influence on the electrochemical processes in the cell. With AVL eSUITE™ you have the possibility to design the thermal system and to detail it afterwards. We will show you how it is done.
