PRECHARGING USING A MOTOR-INVERTER SYSTEM

A system for charging a battery includes a charge port configured to be electrically connected to an inverter and a multi-phase electric motor, the inverter and the electric motor configured to be powered by a battery, and a charging system including a charge port bus configured to electrically connect a charge port to a phase of the electric motor and to a direct current (DC)-DC converter. A phase of the inverter and the electric motor forms a power factor correction (PFC) stage and the DC-DC converter forms part of a DC-DC conversion stage, and the charging system includes a precharge circuit configured to be electrically connected to the charge port bus. The system also includes a controller configured to control the precharge circuit to precharge one or more components of the charging system.
