This study shows a novel online approach for characterizing battery cells or modules in any type of reconfigurable battery system (RBS) for electric driving applications, which allows neighboring cells or modules to switch in parallel. Also, the different representations (time and frequency domain) of conventional battery modeling based on equivalent circuit models (ECM) are described. Finally, it is shown that the balancing current of neighboring cells can be used to characterize the batteries’ dynamic parameters and, as a result, estimate the state of health (SoH) and remaining useful life (RUL) of each cell individually.
