The technical challenges and difficulties of the lithium-ion battery management are primarily in three aspects. Firstly, the electro-thermal behavior of lithium-ion batteries is complex, and the behavior of the system is highly non-linear, which makes it difficult to model the system.
Quality management for complex process chains Due to the complexity of the production chain for lithium- ion battery production, classical tools of quality management in production, such as statistical process control (SPC), process capability indices and design of experiments (DoE) soon reach their limits of applicability .
Lithium-ion battery safety is one of the main reasons restricting the development of new energy vehicles and large-scale energy storage applications . In recent years, fires and spontaneous combustion incidents of the lithium-ion battery have occurred frequently, pushing the issue of energy storage risks into the limelight .
A knowledge-based, multi-physics-constrained fast charging strategy for lithium-ion batteries is proposed , which considers the thermal safety and aging problems. A model-based state observer and a deep reinforcement learning-based optimizer are combined to obtain the optimal charging strategy for the battery.
Hence, a control model needs to develop to enhance the protection of battery. Therefore, the key issue of the research is to investigate the performance of Li-ion battery energy management system (BMS) for electrical vehicle applications by monitoring and balancing the cell voltage level of battery banks using Simulink software.
The advantages of lithium-ion batteries are very obvious, such as high energy density and efficiency, fast response speed, etc , . With the reduction of manufacturing costs of the lithium-ion batteries, the demand for electrochemical energy storage is increasing , .

The chemical makeup of lithium-ion batteries makes them susceptible to overheating if not managed properly. Lithium-ion battery fires are typically caused by thermal runaway, where internal temperatures rise uncontrollably. Lithium-ion battery fires can be prevented through careful handling, proper storage and regular monitoring.
Lithium-ion batteries contain volatile electrolytes, and when exposed to high temperatures or physical damage, they can release flammable gases. Ejection. Batteries can be ejected from a battery pack or casing during an incident thereby spreading the fire or creating a cascading incident with secondary ignitions/fire origins. Risk of reignition
