1. A reconfigurable traction-charging system residing in an electric apparatus having a rechargeable battery, comprising:
a motor comprising a stator having a plurality of stator teeth and a plurality of stator windings wounded on the plurality of stator teeth;
an inverter comprising a plurality of power switch devices;
an output rectifier;
a configurator comprising a plurality of contactors coupled with the plurality of stator windings and the plurality of power switch devices; and
a controller for controlling the plurality of power switch devices and the plurality of contactors, so as to configure the system to operate in one of a traction mode and a charging mode, wherein
under the traction mode, the rechargeable battery supplies electric energy to the motor via the inverter; and
under the charging mode:
the plurality of contactors can be opened or closed by the controller such that the inverter can form both: (1) a direct DC charging bypass, allowing a DC charging source to directly power the rechargeable battery; and (2) a multi-stage power regulator, regulating at least one of current and voltage prior to powering the rechargeable battery.
