The main structure of a complete BMS for low or medium voltages is commonly made up of three ICs: an analog front-end (AFE), a microcontroller (MCU), and a fuel gauge (see Figure 1). The fuel gauge can be a standalone IC, or it can be embedded in the MCU. The MCU is the central element of the BMS, taking information from both the AFE and fuel gauge and interfacing with
Currently, the main drivers for developing Li-ion batteries for efficient energy applications include energy density, cost, calendar life, and safety.

It would be unwise to assume ''conventional'' lithium-ion batteries are approaching the end of their era and so we discuss current strategies to improve the current and next generation systems
Lithium-ion batteries are one of the most popular energy storage systems today, for their high-power density, low self-discharge rate and absence of memory effects. However, some challenges such as flammability, high cost, degradation, and poor electrochemical performances of different components such as cathode, anode, collectors, electrolyte
The manufacturing data of lithium-ion batteries comprises the process parameters for each manufacturing step, the detection data collected at various stages of production, and the performance parameters of the battery [25, 26].
The products produced during this time are sorted according to the severity of the error. In summary, the quality of the production of a lithium-ion battery cell is ensured by monitoring numerous parameters along the process chain.
With the rapid development of new energy vehicles and electrochemical energy storage, the demand for lithium-ion batteries has witnessed a significant surge. The expansion of the battery manufacturing scale necessitates an increased focus on manufacturing quality and efficiency.
It begins with a preparation stage that sorts the various Li-ion battery types, discharges the batteries, and then dismantles the batteries ready for the pretreatment stage. The subsequent pretreatment stage is designed to separate high-value metals from nonrecoverable materials.
The benefit of the process is that typical lithium-ion battery manufacturing speed (target: 80 m/min) can be achieved, and the amount of lithium deposited can be well controlled. Additionally, as the lithium powder is stabilized via a slurry, its reactivity is reduced.
