ESC test results of 6S battery modules in Groups 6 and 7. (A–B) Module currents and voltages; (C–D) Voltage of cells; (E–F) Temperature of cells. Following a period of discharging, some cells become damaged, thereby terminating the module's discharge.
Too long battery wires will kill your ESC over time! There are two fail mechanisms at work. Voltage spikes higher than battery voltage. The spikes will destroy discrete transistors and integrated circuits through breakdown. Higher current flowing through the standard input capacitors already on ESC (large colourful barrelshaped).
The obtained ESC fault characteristics provide the differentiation of ESCs from other types of battery faults. This research highlights the differences in ESC behavior between individual cells and series-parallel modules, revealing that the weakest cell in a module often determines the duration and severity of an ESC event.
The results show that the peak current of the battery module ESC is close to that of a single cell ESC, however, its peak temperature and released capacity during ESC process are much lower, which are only 79 % and 57 % of that of a single cell ESC, respectively.
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.
SOC levels from 10 % to 100 % were studied, highlighting that higher SOCs lead to more severe short-circuit reactions. These insights underscore the importance of considering cell type, capacity, temperature, and SOC in evaluating battery safety and performance under ESC conditions. Table 1. The experimental studies on ESC faults. Table 2.
