A method includes receiving an indication of a charging current received at an on-board charging circuit of a vehicle from a source having a charging voltage. The on-board charging circuit includes a multi-phase traction motor, an inverter electrically coupled to the multi-phase traction motor and including an upper set of switching elements and a lower set of switching elements, and an energy storage device (ESD) electrically coupled to the inverter and having a storage voltage. The method includes determining whether the charging voltage is greater than or equal to the storage voltage. When the charging voltage is greater than or equal to the storage voltage, the method includes instructing at least one switching element in the upper set to operate in an on state and all of the switching elements in the lower set in an off state to cause fast charging of the ESD using the charging current.
