In addition to improving individual LIB cells, several researches were focused on strategies to obtain better battery packs. Every single cell in the battery pack needs a contact for its cell terminals, which raises the necessity of an automated contacting process with low joint resistances to reduce the energy loss in the cell transitions.
One effective method to improve the reliability of lithium-ion battery packs (LIBPs) is through the use of fault-tolerant technology based on redundant design [4, 5]. However, it's important to note that this approach is often accompanied by changes in the structure and layout, which can also impact the reliability of the battery packs.
However, a battery pack with such a design typically encounter charge imbalance among its cells, which restricts the charging and discharging process . Positively, a lithium-ion pack can be outfitted with a battery management system (BMS) that supervises the batteries' smooth work and optimizes their operation .
Moreover, a lithium-ion battery pack must not be overcharged, therefore requires monitoring during charging and necessitates a controller to perform efficient charging protocols [13, 23, 32, 143 - 147].
The second scenario for the reuse of lithium-ion battery packs examines the problem of assembling a pack for less-demanding applications from a set of aged cells, which exhibit more variation in capacity and impedance than their new counterparts.
The expanding use of lithium-ion batteries in electric vehicles and other industries has accelerated the need for new efficient charging strategies to enhance the speed and reliability of the charging process without decaying battery performance indices.
