Modeling/simulation of battery safety applied to aeronautics

Abstract : The need for Li-ion batteries is essential both for the more electric aircraft and for all new forms of all-electric or hybrid-electric propulsion. A common feature of the different aeronautical applications is the important safety need and the absence of catastrophic events linked to the use of such batteries, which are known for their high power density but also for their risk of thermal runaway that can lead to uncontrolled physical phenomena on board. The phenomenon of thermal runaway is globally understood from the physical point of view but very difficult to model because it is a very exothermic phenomenon. We propose in this article to make a complete point on this subject and in particular, to approach the modeling of the safety of the batteries applied to the future aircraft and the phenomena of thermal runaway.
