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.
In this paper, the short-circuit fault of DC bus in energy storage power station is analyzed and simulated. The short circuit of DC bus is composed of three parts: short circuit current provided by energy storage battery, short circuit current provided by power grid and short circuit current provided by DC energy storage capacitor.
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).
The short-circuit fault in the series module terminates with the failure of Cell 05, while in the series-parallel module, it terminates after the sequential failure of Cells 07–09. Therefore, the termination of the short circuit in both types of modules depends on the cell with the highest internal resistance.
As shown in Fig. 23 (A) and (B), the short circuit is triggered at 1 s, resulting in a significant voltage drop in both cases, with the voltage of the failed cells dropping the most. Fig. 23 (C) and (D) illustrate the current, showing a significant variation in short-circuit currents among the cells in the series-parallel module.
External short circuit (ESC) faults pose severe safety risks to lithium-ion battery applications. The ESC process presents electric thermal coupling characteristics and becomes more complex when the batteries operate in large group, which often lead to serious consequences.

Moreover, an open circuit fault occurs when the winding is disconnected; likewise, a phase-to-ground fault occurs when some phase is connected to the ground. More critical motor faults are a short circuit between the turns of two phases (phase-to-phase fault) or a short circuit between turns in all phases, although these faults rarely happen [5].
Renewable energy generators (REGs) usually employ power electronic devices for connecting with the grid, which makes their fault characteristics completely different from those of conventional synchronous generators. In the existing …
