Up to 40 % of the components of a conventional battery pack can be saved by eliminating the module level [1]. As a result, the costs for the passive materials in the battery decrease, and at the same time, the development effort can be reduced. The high degree of integration also reduces system complexity and minimizes the need for interfaces.
High efficiency of battery packs can be achieved by effectively charging, discharging and resting the battery cells at the right time. Unbalanced cells in a pack degrade the pack's performance and also the SOH of other cells. Till now, the SOH as a driving factor for reconfiguration has been least explored, except for the work done in .

The approach effectively allows each cell to live its best – and longest – life. According to Stanford professor and senior study author Simona Onori, initial simulations suggest batteries managed with the new technology could handle at least 20% more charge-discharge cycles, even with frequent fast charging, which puts extra strain on the battery.
Running simulations with the model suggested that a modern battery pack can be optimized and controlled by embracing differences among its constituent cells. Onori and colleagues envision their model being used to guide development of battery management systems in the coming years that can be easily deployed in existing vehicle designs.
Battery pack inconsistency is the main limiting factor for improving battery pack capacity utilization, and poses major safety hazards to energy storage systems. To solve this problem, a maximum capacity utilization scheme based on a path planning algorithm is proposed.
Increasing the operating time as well as slowing down the health degradation of battery has been one of the greatest challenges. Earlier, different kinds of algorithms or methods for discharging has been proposed. In most of the cases, the recovery effect and rate capacity effect of the batteries were exploited to increase the operating time.
