Abstract

A multi-user electric vehicle charging station is described, and includes a movable charging apparatus that is disposed to service a plurality of parking spaces and a controller that operatively connects to the movable charging apparatus. A human/machine interface device communicates with the controller and includes an interface device including user-selectable states including a user identification, identification of a specific one of the parking spaces and an expected departure time associated with a vehicle parked in the specific one of the parking spaces.

First claim

1 . A multi-user electric vehicle charging station, comprising:
a movable charging apparatus that is disposed to service a plurality of parking spaces; a controller operatively connected to the movable charging apparatus; a human/machine interface device in communication with the controller, the human/machine interface device including user-selectable states including a user identification, identification of a specific one of the parking spaces, a present battery level, and an expected departure time associated with a vehicle parked in the specific one of the parking spaces.

2 . The multi-user electric vehicle charging station of claim 1 , wherein the controller includes a wireless communications transceiver; and wherein the human/machine interface device comprises a remotely located mobile device employing wireless communications and a mobile software application.

3 . The multi-user electric vehicle charging station of claim 1 , wherein the movable charging apparatus is disposed to translate on a track that extends across the plurality of parking spaces.

4 . The multi-user electric vehicle charging station of claim 3 , wherein the track comprises a ground-level track.

5 . The multi-user electric vehicle charging station of claim 3 , wherein the track comprises an overhead track.

6 . The multi-user electric vehicle charging station of claim 1 , further comprising a communication device capable of communicating with a remote server.

7 . The multi-user electric vehicle charging station of claim 1 , wherein the movable charging apparatus disposed to service a plurality of parking spaces

8 . The multi-user electric vehicle charging station of claim 1 , wherein the movable charging apparatus include an end-effector that is disposed to service the plurality of parking spaces.

9 . The multi-user electric vehicle charging station of claim 8 , wherein the end effector is in mechanical communication with a base through a plurality of rigid arm members.

10 . The multi-user electric vehicle charging station of claim 8 , wherein the end effector is in mechanical communication with a base through a flexible electrical cable.

11 . The multi-user electric vehicle charging station of claim 8 , wherein the end effector is manually positioned to charge a vehicle.

12 . The multi-user electric vehicle charging station of claim 8 , wherein the end effector is automatically positioned to charge a vehicle.

13 . The multi-user electric vehicle charging station of claim 1 , wherein the movable charging apparatus is electrically connected to a power delivery circuit.

14 . The multi-user electric vehicle charging station of claim 13 , wherein the power delivery circuit is configured to receive either one- or three-phase AC electrical power.

15 . The multi-user electric vehicle charging station of claim 13 , wherein the power delivery circuit is configured to output a direct current (DC) electrical power.

16 . The multi-user electric vehicle charging station of claim 13 , wherein the power delivery circuit is configured to output an alternating current (AC) electrical power.

17 . A method for controlling operation of a movable charging apparatus of an electric vehicle charging station that is disposed to service vehicles in a plurality of parking spaces, the method comprising:
upon entry of a vehicle into one of the vehicle parking spaces accompanied with a charging request for a vehicle battery:
determining, for each of a plurality of vehicles parked in the parking spaces, states for input parameters for each of the vehicles;
determining, by a controller, a preferred charging sequence for the plurality of vehicles parked in the parking spaces based upon the states for input parameters for each of the vehicles, and
sequentially charging the plurality of vehicles parked in the parking spaces employing the movable charging apparatus based upon the preferred charging sequence.

18 . The method of claim 17 , wherein determining states for input parameters for each of the vehicles comprises determining a vehicle arrival time, a remaining power level for a vehicle battery, a total electric power capacity of the vehicle battery, a period of time required to achieve a target charge level for the vehicle battery, an average parking time, an expected departure time, and credit points.

19 . The method of claim 17 , wherein the preferred charging sequence comprises a charging queue that identifies each of the vehicles and its place in the queue.

20 . A method for controlling operation of a movable charging apparatus of an electric vehicle charging station that is disposed to service vehicles in a plurality of parking spaces, the method comprising:
upon entry of a vehicle into one of the vehicle parking spaces accompanied with a charging request for a vehicle battery:
determining, for each of a plurality of vehicles parked in the parking spaces, a vehicle arrival time, a remaining power level for the vehicle battery, and an expected departure time,
determining, by a controller, a preferred charging sequence for the plurality of vehicles parked in the parking spaces based upon the corresponding vehicle arrival times, the remaining power levels for the vehicle batteries and the expected departure times, and
sequentially charging the plurality of vehicles parked in the parking spaces employing the movable charging apparatus based upon the preferred charging sequence.
