Abstract

There is described an electric vehicle charging station for charging an electric vehicle, comprising: an electrical connector electrically connectable to a source of electrical energy, the electrical connector adapted for connecting to a battery of the electric vehicle; a frame having a connector receiving portion for receiving the electrical connector; a locking unit mounted to the frame for preventing a user access to the electrical connector; and a control unit operatively connected to the locking unit, the control unit for verifying rights of a user to access the electrical connector and unlocking the locking unit upon successful verification of the user rights to provide the user access to the electrical connector.

Claims

1. An electric vehicle charging station for charging an electric vehicle, comprising:

an electrical connector electrically connectable to a source of electrical energy, the electrical connector adapted for connecting to a battery of the electric vehicle;

an electrical cable having a first end connected to the electrical connector and a second end connectable to the source of electrical energy;

a frame having a connector receiving portion for receiving the electrical connector;

a locking unit mounted to the frame for preventing a user access to the electrical connector;

the locking unit comprising a connector cover movable between a closed position in which the electrical connector is enclosed in the receiving portion to prevent the user access to the electrical connector, and an open position in which the electrical connector is accessible and removable from the receiving portion, and a connector locking mechanism for locking the connector cover when in the closed position, wherein the frame further comprises a cable receiving portion for receiving the electrical cable;

a control unit operatively connected to the locking unit, the control unit for verifying rights of a user to access the electrical connector and unlocking the locking unit upon successful verification of the user rights to provide the user access to the electrical connector; and

a cable cover pivotally secured to the frame adjacent to the cable receiving portion and movable between a first position in which the electrical cable is enclosed in the cable receiving portion to prevent the user access to the electrical cable, and a second position in which the electrical cable is accessible and removable from the cable receiving portion, and

a cable locking mechanism controlled by the control unit for locking the cable cover when in the first position.

2. The electric vehicle charging station of claim 1, wherein the connector cover is shaped and sized to cover substantially an entirety of the electrical connector when inserted in the connector receiving portion.

3. The electric vehicle charging station of claim 2, wherein the connector cover is pivotally secured to the frame.

4. The electric vehicle charging station of claim 1, wherein the connector cover is integral with the cable cover.

5. The electric vehicle charging station of claim 1, wherein the electrical cable is retractably mounted to the frame in order to retract the electrical cable in the cable receiving portion of the frame.

6. The electric vehicle charging station of claim 5, further comprising a motor, a roller secured to the frame and drivable by the motor, and a retracting cable having a first end secured to the roller and a second end secured to the electrical cable, the motor being controlled by the control unit for rolling the retracting cable on the roller in order to retract the electrical cable in the cable receiving portion.

7. The electric vehicle charging station of claim 1, further comprising a position sensor for determining whether the electrical connector is positioned in the connector receiving portion, the control unit being connected to the position sensor and adapted to terminate a transaction for the user only when the position sensor determines that the electrical connector is positioned back in the connector receiving portion.

8. The electric vehicle charging station of claim 1, wherein the electrical connector is fixedly secured to the frame in the connector receiving portion.

9. The electric vehicle charging station of claim 1, wherein the control unit is adapted to identify the user and unlock the locking unit upon successful identification of the user.

10. A method for charging an electric vehicle, comprising:

at an electric vehicle charging station, verifying rights of a user to use the charging station for charging the electric vehicle;

upon successful verification, unlocking a locking unit mounted to a frame of the charging station, the locking unit preventing the user access to an electrical connector electrically connected to a source of electrical power and positioned in a receiving portion of the frame, thereby providing the user access to the electrical connector, said unlocking the locking unit comprising unlocking a locking mechanism operatively connected to a connector cover movable between a closed position in which the electrical connector is enclosed in the receiving portion, thereby preventing the user access to the electrical connector, and an open position in which the electrical connector is accessible and removable from the receiving portion;

unlocking a cable cover locked in a first position by a control unit, the cable cover being pivotally secured to the frame adjacent to the cable receiving portion and movable between the first position in which the electrical cable is enclosed in the cable receiving portion to prevent the user access to the electrical cable, and a second position in which the electrical cable is accessible and removable from the cable receiving portion; and

the user electrically connecting a battery of the electric vehicle to the electrical connector, thereby charging the electric vehicle.

11. The method of claim 10, wherein said verifying rights comprises identifying the user.

12. The method of claim 10, wherein said verifying rights comprises receiving a payment from the user.

13. The method of claim 10, wherein the step of the user electrically connecting the battery comprises:

the user opening the connector cover, electrically connecting the battery to the electrical connector, and closing the connector cover; and

providing electrical energy to the battery via the electrical connector.

14. The method of claim 13, further comprising:

locking the connector cover during said providing electrical energy to the battery;

unlocking the connector cover once the battery is recharged;

said user disconnecting the battery and positioning the electrical connector back in the receiving portion;

terminating an operation of the user only when the electrical connector has been positioned back in the receiving portion; and

locking the connector cover.
