Various abusive behaviors and working conditions can lead to battery faults or thermal runaway, posing significant challenges to the safety, durability, and reliability of electric vehicles. This paper investigates battery faults categorized into mechanical, electrical, thermal, inconsistency, and aging faults.
Battery faults represent a broad spectrum of issues that can occur in a battery system, significantly impacting its performance, safety, and longevity. These anomalies, often complex and multifaceted, range from minor deviations in battery operation to severe incidents, leading to catastrophic damage and failure.
Therefore, effective abnormality detection, timely fault diagnosis, and maintenance of LIBs are key to ensuring safe, efficient, and long-life system operation [14, 15]. Battery fault diagnosis can assess battery state of health based on measurable external characteristics, such as voltage and current [16, 17].
They analyze the mechanisms of battery faults, classifying them into mechanical, electrical, thermal, inconsistency, and aging faults, and use model-based, data-driven, and knowledge-based methods for fault diagnosis. Battery faults are primarily indicated by changes in voltage, current, temperature, SOC, and structural deformation stress.
In battery system fault diagnosis, finding a suitable extraction method of fault feature parameters is the basis for battery system fault diagnosis in real-vehicle operation conditions. At present, model-based fault diagnosis methods are still the hot spot of research.
Among battery thermal faults, the most common fault is excessive temperature, which can cause significant damage to the battery unit and the entire system. Thermal faults in battery systems, their consequences, and suggested remedies are outlined in Table 4.

Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
Different lithium chemistries have varying cut-off voltages based on their unique characteristics: Lithium-Ion (Li-ion): Generally has a cut-off voltage of around 2.5V to 3.0V. Lithium Iron Phosphate (LiFePO4): Typically set between 2.0V and 2.5V, allowing for deeper discharge without damage.
