6 FAQs about [What is the reaction of short circuit in energy storage charging pile ]

What causes a short circuit in a battery?

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.

What happens if a battery module triggered a short circuit?

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).

What happens if a short circuit is triggered at 1 s?

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.

What happens after a short circuit?

After the internal short circuit, the gaps between the positive electrode material particles of LFP become tighter and only the separator structure is significantly affected.

What is Rp(tesc) when a battery is triggered into ESC?

When the battery is triggered into ESC from a resting state, Rp(tESC) is 0. The empirical formula of battery UOC was obtained in previous studies . As shown in Fig. 15 (A), it was observed that the ohmic resistance at the onset of the ESC increases in tandem with the rise in the short resistance.
