Defining energy storage system objectives. First, the building owner and consulting engineers must define project goals. The following questions can help determine the project''''s objectives,
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.
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.
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).
Chen 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 . Kriston et al. divided the battery short-circuit current into 3 stages.
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.
