To reduce the CO2emissions and achieve the 80% reduction target by 2050, it is essential that the electric vehicle (EV) development and their adoption by the public are accelerated. This requires removal of one of the major obstacles, which is the so-called range anxiety. The first and the most obvious approach to relieving EV driver’s range anxiety is to provide the vehicle with an on-board charger, so that the driver can charge the battery at any electric grid connection point. Such an on-board battery charger should provide means for both slow charging (from a single-phase grid) and fast charging (from a three-phase grid).
A preferable solution for this purpose is the use of integrated on-board chargers: the idea is to reuse the existing components of an EV, which are already in place for the propulsion mode of operation. This lecture looks at the currently available solutions that integrate some or all of the already existing EV components into the charging process and then concentrates on the solutions based on machines and converters with more than three phases (multiphase systems). A whole range of entirely novel solutions, based on using machines with different phase numbers, have been developed in the last few years. All are characterised with the zero torque development during charging process. A further very important property of these solutions is that, in addition to the charging mode, vehicle-to-grid (V2G) operation is also possible without any modifications whatsoever. The stator winding configurations encompassed by the presentation are the symmetrical six-phase, asymmetrical six-phase, symmetrical and asymmetrical nine-phase and five-phase and all topologies enable connection to either three-phase or single-phase grid.

Emil Levi received his MSc and the PhD degrees in Electrical Engineering from the University of Belgrade, Yugoslavia in 1986 and 1990, respectively. From 1982 till 1992 he was with the Dept. of Electrical Engineering, University of Novi Sad. He joined Liverpool John Moores University, UK in May 1992 and since September 2000 Professor of Electric Machines and Drives. He served as a Co-Editor-in-Chief of the IEEE Trans. on Industrial Electronics in the 2009-2013 period and is currently Editor-in-Chief of the IET Electric Power Applications and an Editor of the IEEE Trans. on Energy Conversion. He is a Fellow of the IEEE and the recipient of the Cyril Veinott award of the IEEE Power and Energy Society for 2009 and the Best Paper award of the IEEE Trans. on Industrial Electronics for 2008. He is also a recipient of the European Power Electronics (EPE) Association “Outstanding Achievement Award” for 2014 and “Professor Istvan Nagy Award” of the Power Electronics and Motion Control (PEMC) Council for 2018.
