Electric Vehicle (EV) owners are confronted by the limited compatibility of available charging infrastructures. Therefore, this paper is focused on presenting a Configurable Modular Multilevel Converter (CMMC) for a universal and flexible integrated charging system, where the motor windings are used as filter during the charging operation and the battery pack is split into modules. This concept is designed for a large range of charging infrastructure; from AC household basic supply to AC or DC ultrafast charging. Particular attention will be paid to the battery management system.
