AI Customer ServiceChen et al. found that the higher the state of charge (SOC) during a short circuit leads the battery to heat up more quickly and inflict more damage, and a lower SOC lowers the short circuit current and lessens damage while releasing more short circuit capacity [ 16 ]. Kriston et al. divided the battery short-circuit current into 3 stages.
Zhang et al. performed ESC experiments at 0.6 m and 5.0 m for 1 s, 30 s, and 180 s, respectively, and discovered that the diffusion impedance considerably increased as the short-circuit resistance reduced and the short-circuit time rose, resulting in an acceleration of the loss in battery life [ 19 ].
The risks of external short-circuit of battery modules with different voltage levels are tested for the first time. Two types of typical risk modes and influencing factors of ESC of battery modules are analyzed and proposed. The effectiveness and limitations of weak links for protection in external short circuits of battery modules are verified.
The inconsistent behavior among batteries and heat transfer between them are considered the main reasons why the duration of a short circuit in a module is typically shorter than that of an individual cell. As Fig. 16 (E) and (F) demonstrate, failed cells exhibit higher surface temperatures compared to functioning ones.
This is due to two main reasons: first, a short circuit in a series module can cause some cells to undergo polarity reversal (as shown in Fig. 15 C and D), potentially leading to electrode material damage, electrolyte decomposition, and gas generation, thereby accelerating battery degradation .
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.
