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 .

Conclusions This study developed a model-based methodology for use in the design of battery packs for automotive applications. This methodology is based on a multi-domain simulation approach to allow electric, thermal and geometric evaluations of different battery pack configurations, with particular reference to Li-NMC technology.
R-BMS must supply the desired power at any point of time without any breaks. In case of dynamically reconfigurable battery packs, there are two challenges hindering the system from delivering an uninterrupted supply of desired power: One is the Re-configuration time (R-time) delay and other is the transient load supply .
A multi-domain model-based methodology is proposed to support the design of new battery packs. Electro-thermal models of Li-NMC storage cells have been investigated and validated by means of laboratory testing campaigns. Thermal effects of forced air Battery Thermal Management Systems have been evaluated.
Battery pack with air cooling scheme. In each duct, the air flow stream is a fraction of the total mass flow provided by the fan, depending on the position of the pipe in the layout. In this configuration, all the rectangular pipes start from the same inlet and are divided during the heat exchange with battery cells.
