2021 World Electric Vehicle Journal  
This article presents an innovative self-reconfigurable battery (SRB) architecture, which is able to generate directly at its output any waveform signals. Thanks to that specific characteristic of the proposed system, it is even possible to dispense with any AC charger. Although the individual ability of each cell in the battery pack to perform an efficient active cell balancing has been already studied in the literature, the system presented in this article is the first of its kind.
