The battery that had undergone an external short circuit reached its critical value of failure at a cycle of about 100 cycles. External short circuit would accelerate the rate of increase in internal resistance of lithium-ion battery. Normally, the internal resistance of the battery doubled at approximately 350 cycles.
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.
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.
Cai et al. studied the experimental simulation of internal short circuit of lithium-ion battery polymer . They found that the risk of thermal runaway during an internal short circuit increases as the battery’s state of charge (SOC) increases.
