ELECTRIC VEHICLE AND METHOD OF DRIVING AND CHARGING THE SAME

摘要

A method of charging an electric vehicle. The electric vehicle includes a battery, an inverter, and a motor including at least three-phase coil windings. When the electric vehicle is in a driven state, a direct current output from the battery is converted into a three-phase alternating current by a forward operation control of the inverter. The three-phase alternating current is output to the motor and drives the motor to operate. When the electric vehicle is in a charging state, an external three-phase alternating current is input into the inverter via three charging inductors and converted into the direct current by a reverse operation control of the inverter to charge the battery.

1. A method of charging an electric vehicle, the electric vehicle comprising a battery, an inverter, and a motor comprising at least three-phase coil windings; the method comprising:
a) when the electric vehicle is in a driven state, outputting a direct current by the battery to the inverter, converting the direct current by the inverter into a three-phase alternating current through a forward operation control, and outputting the three-phase alternating current to the motor to drive the motor to operate; and b) when the electric vehicle is in a charging state, introducing an external three-phase alternating current to the inverter via three charging inductors, and converting the external three-phase alternating into the direct current by the inverter through a reverse operation control, and charging the battery with the direct current.
