The internal short circuit was triggered by the rupture and deformation of structures within the battery, such as electrodes and separators. The higher the battery SOC, the faster the average temperature rise rate, leading to more severe thermal runaway.
Fig. 16 presents the ESC test results of 6-series battery modules from Groups 6 and 7. Upon triggering the short circuit, the short current rapidly escalates to 150 A, and the module voltage plummets to approximately 0.5 V, as illustrated in Fig. 16 (A) and (B).
They found that the battery capacity had a greater impact on the reaction process of external short circuits. Conte et al. studied the influence of different battery capacities and showed that the external short-circuit current increases with the capacity of the battery.

Thermal Model: This part of the model utilizes a first-order thermal network to simulate the dynamic temperature response of the lithium-ion battery.
By comparing the curves, it is also found that the higher the SOC, the smaller the displacement corresponding to the short circuit, indicating that high SOC batteries are more prone to internal short circuits when subjected to external force and displacement.
