6 FAQs about [Battery discharge current is too large fault]

What is the most dangerous fault in a battery system?

Electrical fault The electrical fault in the battery system is one of the most dangerous fault types. Meanwhile, it is the most common fault. The electrical fault mainly includes ISC fault, ESC fault, over-charge/over-discharge fault, insulation fault, sensor fault, communication fault, and contactor fault.

What are the main faults of a battery system?

Table 1. Faults performance of the battery system and interrelationships. Mechanical deformation, Over-charge/Over-discharge fault, induction of active materials, thermal fault. It is often accompanied by discharge and exothermic, and the main fault activates BTR. Connection fault, mechanical deformation, aging fault, water immersion.

How is a battery open fault diagnosed?

In addition, Zhou et al. also performed real-time fault diagnosis for battery open faults based on a dual-expansion Kalman filtering method, which uses only the current of the battery pack and the terminal voltages of the parallel battery modules in addition to other sensor data .

What is the progression of battery faults?

Fig. 14 shows the progression of battery faults, including the early development (fault precursor), fault occurrence (fault features), and further deterioration leading to disasters. Current research focuses on pre-warning by studying precursors and diagnosing faults through feature extraction.

What happens if a battery is overcharged?

The severe over-charge fault will result in excessive metal dissolution, material phase change, cathode electrolyte decomposition, and other phenomena, causing an ISC of the battery and eventually triggering BTR [67, 68]. Battery inevitably occurs over-charge during the charge process. Over-charge faults can arise from various sources.

Why does the terminal voltage decrease during an ISC fault?

The abnormal self-discharge current is relatively weak in the initial stage of ISC fault due to the high equivalent ISC resistance. Thus, the terminal voltage of the battery gradually decreases, resembling the behavior observed in aged batteries during the initial stage of an internal short circuit fault .
