This example simulates an air-cooled cylindrical 18650 lithium-ion battery during a charge-discharge cycle, followed by a relaxing period. A lumped battery model is used to model the battery cell chemistry, and a two-dimensional axisymmetrical model is used to model the temperature in the battery.
We present a one-dimensional, radial, coupled degradation-electrochemical-thermal (DET) model of a large format cylindrical lithium ion cell. The model consists of reduced order equations that describe the electrochemical phenomena, including that associated with degradation, coupled with an approximate model of thermal behavior.
Conclusions A distributed 3D coupled electro-thermal equivalent circuit network (ECN) model of cylindrical lithium-ion batteries is used to study the effect of cell design and cooling approach on performance. Multiple tab configurations and thermal management approaches are considered for 2170 and 4680 cells.
The demand for large format lithium-ion batteries is increasing, because they can be integrated and controlled easier at a system level. However, increasing the size leads to increased heat generation risking overheating. 1865 and 2170 cylindrical cells can be both base cooled or side cooled with reasonable efficiency.
A lumped battery model is used to model the battery cell chemistry, and a two-dimensional axisymmetrical model is used to model the temperature in the battery. The two models are coupled by the generated heat source and the average temperature using the Electrochemical Heating multiphysics coupling node.
