The state of the battery is mainly defined by two parameters: state of charge (SOC) and, state of health (SOH). Both parameters influence performance in the battery and are dependant on each other (Jossen et al., 1999).
For this reason, the safety of the battery pack is also related to the performance of the mechanical parts. By reducing the weight, the efficiency of the battery can be improved in terms of life cycle and range, at the same time, the battery has to preserve high strength and resistance to vibrations (Shui et al., 2018).
The battery pack embraces different systems of interrelated subsystems necessary to meet technical and life requirements according to the applications (Warner, 2015). The expand of the technology depends on the cost, safety, cycle life, energy density and power density.
Uneven temperature distribution leads to different charge and discharge behaviours causing electrical unbalance in the modules which reduces the performance of the battery pack. When a battery pack is integrated with the vehicle, it becomes a more complex system confronting many safety problems (Garg et al., 2016).
The performance relies on the quantity and quality of training data, which limits the practical settings. Complexity hinders real-time applications in some scenarios. The proposed method leads to better battery pack performance and longevity. It broadens the industry adoption of LIBs in various applications. 11.
