safety modelling and testing of lithium-ion batteries in electrified vehicles - 18650 battery cell

In order to optimize the safety of the battery, it is important to understand the behavior of the battery when it is subject to abuse.
Most of the early work of battery safety modeling focuses on a battery or an area of interest, such as mechanical or thermal failure.
These efforts may not fully reflect the failure of batteries in automotive applications, where a large number of batteries can perform various physical processes at the same time.
From this perspective, we review the modeling and testing methods for battery safety under abuse conditions.
And then, we came up with a big-scale multi-
Physical modeling and experimental work to solve car battery safety problems
World applications.
In particular, we consider modeling the mechanical, electrical, electro-chemical and thermal behavior of the battery and explore strategies to extend the simulation to the level of the battery module and battery pack.
In addition, we evaluated the safety test methods for the entire automotive hardware suite from battery to packaging.
We also discussed the challenges facing the establishment of this framework and its future direction.
