Electro-thermal coupling model of lithium-ion batteries Firstly, assuming that the whole y – z plane of the battery is divided into M nodes, the electrothermal coupling model of the whole battery is transformed into an electrothermal coupling model with M nodes.
This is because the coupling process is a crucial step for accurate performance and safety of Lithium-ion batteries [142, 143]. Generally, four primary coupling methods are identified in the literature, i.e., direct, sequential, hybrid, and multi-scale.
By coupling the battery’s P2D model with a magnetic field model, a lithium battery-magnetic field coupling model is introduced. This model can calculate the magnetic field distribution around the battery during charge and discharge processes.
