Abstract By re-employing the existing motor windings and inverter in EV’s propulsion system, an on-board fast charger can be built without adding additional power devices, attracting more and more attention. In this paper, the key issues of the integrated charger are summarized firstly. Then, oriented by the issues, the existing solutions from both system topology and control strategy perspectives are reviewed and presented in details. Thereafter, according to the unique structure of the hybrid-excitation machine (HEM), the advantages of HEM-based integrated chargers are introduced. Finally, the development direction of the integrated on-board charger is prospected.
