Abstract

A method and a system for controlling electric vehicles are provided. The method for includes wirelessly authenticating, by the controller, a vehicle and a charger when the vehicle enters stops in the network area of the charger. When the authentication is completed, the controller receives reservation information set from the charger and vehicle and wirelessly performs charging or air conditioning based on the received reservation information.

First claim

What is claimed is:

1 . A method for controlling vehicles, comprising:
authenticating, by a controller, a vehicle and a charger wirelessly when the vehicle enters or stops in a network area of the charger; receiving, by the controller, a reservation information set from the charger and the vehicle when the authentication is completed; and performing, by the controller, wireless charging or air conditioning based on the received reservation information set.

2 . The method of claim 1 , wherein the performing of the wireless charging or air conditioning is performed based on at least one selected from the group consisting of: a priority of the reservation information received from the charger and the vehicle, and receiving time of the reservation information.

3 . The method of claim 2 , wherein the priority is changed depending on a preset priority.

4 . The method of claim 1 , wherein in the wireless authentication of the vehicle and the charger, the vehicle and the charger are both authenticated based on preset identifiers.

5 . The method of claim 1 , wherein the performing of the wireless charging or air conditioning includes:
receiving, by the controller, required information from the charger and the vehicle based on to preset operation modes after the wireless charging or air conditioning is performed.

6 . The method of claim 5 , wherein the required information includes at least one selected from the group of: an external temperature, a charging efficiency, a required current and voltage, an electricity usage of other electrical devices using the same power source as the charger, a midnight electricity availability, a maximum charging current amount, and a required charging time.

7 . The method of claim 1 , wherein the reservation information received from the authenticated vehicle and the charger includes at least one selected from the group of: initial state of charge (SOC) information and reservation time information.

8 . The method of claim 1 , further comprising:
disabling, by the controller, an ignition of the vehicle, after receiving the reservation information; and performing, by the controller, the wireless charging or air conditioning based on the reservation information when a starting condition of the wireless charging or air conditioning is satisfied.

9 . The method of claim 8 , wherein the starting condition includes at least one selected from the group of: a condition regarding whether the vehicle is in a reservation charging time and a condition regarding whether a battery is charged less than a preset level.

10 . The method of claim 1 , further comprising:
performing, by the controller, the wireless charging or air conditioning based on the reservation information received when the vehicle reenters the network area of the charger.

11 . The method of claim 1 , wherein the performing of the wireless charging or air conditioning of the vehicle includes:
calculating, by the controller, wireless charging efficiency using electrical energy supplied to the vehicle divided by required electrical energy transferred from the vehicle to the charger and electrical energy used to charge the vehicle.

12 . The method of claim 11 , wherein the performing of the wireless charging or air conditioning of the vehicle further includes:
retransmitting, by the controller, required electrical energy determined based on the calculated wireless charging efficiency and temperature of the vehicle.

13 . The method of claim 1 , wherein the performing of the wireless charging or air conditioning is performed by adjusting performance time of the wireless charging and electrical energy used during the wireless charging or air conditioning based on received electrical charges information from the charger or electrical energy information used by other loads.

14 . A system for controlling electric vehicles, comprising: a charger having a network area to wirelessly communicate with a vehicle and configured to charge the vehicle; and
a controller configured to:
receive an input command;
execute communication between the vehicle and the charger;
execute wireless charging and air conditioning of the vehicle;
authenticate the vehicle and the charger when the vehicle enters or stops in the network area; and
receive reservation information set from the charger and the vehicle, when the authentication is completed to execute the wireless charging and air conditioning of the vehicle.

15 . The system for controlling electric vehicles of claim 14 , wherein the wireless charging and air conditioning is executed based on at least one selected from the group consisting of: a priority of the reservation information received from the charger and the vehicle, and receiving time of the reservation information.

16 . The system for controlling electric vehicles of claim 15 , wherein the priority is changed based on a preset priority.

17 . A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:
program instruction that receive and input command; program instructions that execute communication between a vehicle and a charger; program instructions that execute wireless charging and air conditioning of the vehicle; program instructions that authenticate the vehicle and the charger when the vehicle enters or stops in the network area; and program instructions that receive reservation information set from the charger and the vehicle, when the authentication is completed to execute the wireless charging and air conditioning of the vehicle.

18 . The non-transitory computer readable medium of claim 17 , wherein the wireless charging and air conditioning is executed based on program instructions that execute charging and air conditioning based on at least one selected from the group of: a priority of the reservation information received from the charger and the vehicle, and receiving time of the reservation information.

19 . The non-transitory computer readable medium of claim 18 , wherein the priority is based on program instructions that change the priority based on a preset priority.
