The short circuit in a lithium iron phosphate battery pack can be caused by a single factor or the interaction of multiple factors. What Is the “Micro Short Circuit” in the LiFePO4 Battery？
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.
Additionally, for the study of lithium-ion batteries with internal short circuits, we need to pay more attention to the maximum temperature and temperature rise rate of the battery. In this section, experiments and analysis were conducted on cells A and B at 40 % SOC without thermal runaway.
Abstract: External short circuit (ESC) and overcharge are two types of electrical failures in lithium-ion batteries for electric vehicles. Experimental study has been conducted to quickly and accurately diagnose these faults, which is critical to ensure battery safety.
What Is the “Micro Short Circuit” in the LiFePO4 Battery？ A short circuit of a LiFePO4 battery refers to a situation where the separator between the positive and negative electrodes is compromised, either due to dust particles piercing it or low-quality separator materials leading to reduced surface area or damage.
