System and method for providing information on available charging stations based on DTE

1 . A vehicle charging control system, comprising:

a vehicle configured to identify whether a distance to empty (DTE) is changed based on charging at a location of a first charging station among at least one charging station and transmit state information of the first charging station, the state information being obtained based on whether the DTE is changed, through a communication module; and

a server configured to receive the state information of the first charging station from the vehicle and notify the vehicle of whether the first charging station is available based on the state information of the first charging station,

wherein the vehicle is further configured to:

determine a first DTE at a first timing, when the vehicle arrives at the first charging station;

determine a second DTE after a predetermined time has elapsed from the first timing at the first charging station; and

determine that the first charging station is in a chargeable state based on the first DTE and the second DTE differing.

2 . The vehicle charging control system of claim 1 , wherein

the state information of the first charging station includes information indicating that it is impossible to perform charging at the first charging station, when the DTE is changed, and

the state information of the first charging station includes information indicating that it is impossible to perform charging at the first charging station, when the DTE is not changed.

3 . The vehicle charging control system of claim 1 , wherein the server includes a memory storing a charging station location information list, receives state information of the at least one charging station from the vehicle, and updates the charging station location information list, based on the received state information of the at least one charging station.

4 . The vehicle charging control system of claim 1 , wherein the server includes a memory storing a charging station location information list and hides location information of the first charging station in the charging station location information list, when it is determined that the first charging station included in the charging station location information list is unavailable and when a number of vehicles visiting the first charging station is greater than or equal to a first threshold.

5 . The vehicle charging control system of claim 4 , wherein the first threshold is adjusted to be less than a threshold when the first charging station is a charging station at which the server obtains state information in real time, when the first charging station is a charging station at which the server does not obtain the state information in real time.

6 . The vehicle charging control system of claim 1 , wherein the server includes a memory storing a charging station location information list and determines that there is an available second charging station at a location where the DTE of the vehicle is changed, when the DTE is changed at a specific location.

7 . The vehicle charging control system of claim 6 , wherein the server registers location information of the available second charging station with the charging station location information list, when a number of vehicles charged at the available second charging station is greater than or equal to a second threshold.

8 . The vehicle charging control system of claim 1 , wherein the state information of the first charging station includes information indicating that it is impossible to perform charging at the first charging station when the vehicle moves to a charging station different from the first charging station, after the vehicle arrives at the first charging station, when a destination or a waypoint is set to the first charging station.

9 . The vehicle charging control system of claim 1 , wherein the server controls such that the first charging station is found by use of at least one of audio video navigation telematics (AVNT), telematics, an application, or a combination thereof, when it is determined that the first charging station is available, and hides location information of the first charging station in a charging station location information list.

10 . A vehicle charging control method, comprising:

identifying, by a vehicle, a distance to empty (DTE) is changed based on charging at a location of a first charging station among at least one charging station;

transmitting, by the vehicle, state information of the first charging station, the state information being obtained based on whether the DTE is changed to a server through a communication module;

receiving, by the server, the state information of the first charging station from the vehicle;

notifying, by the server, the vehicle of whether the first charging station is available based on the state information of the first charging station;

determining, by the vehicle, a first DTE at a first timing, when the vehicle arrives at the first charging station; and

determining, by the vehicle, that the first charging station is in a chargeable state based on the first DTE and the second DTE differing.

11 . The vehicle charging control method of claim 10 , wherein

the state information of the first charging station includes information indicating that it is possible to perform charging at the first charging station, when the DTE is changed, and

the state information of the first charging station includes information indicating that it is impossible to perform charging at the first charging station, when the DTE is not changed.

12 . The vehicle charging control method of claim 10 , further comprising:

receiving, by the server, state information of the at least one charging station from the vehicle; and

updating, by the server, a charging station location information list stored in a memory included in the server, based on the received state information of the at least one charging station.

13 . The vehicle charging control method of claim 10 , further comprising:

hiding, by the server, location information of the first charging station in a charging station location information list stored in a memory included in the server, when it is determined that the first charging station included in charging station location information list is unavailable and when a number of vehicles visiting the first charging station is greater than or equal to a first threshold.

14 . The vehicle charging control method of claim 13 , wherein the first threshold is adjusted to be less than a threshold when the first charging station is a charging station at which the server obtains state information in real time, when the first charging station is a charging station at which the server does not obtain the state information in real time.

15 . The vehicle charging control method of claim 10 , further comprising:

determining, by the server, that there is an available second charging station at a location where the DTE of the vehicle is changed, when the DTE is changed at a specific location.

16 . The vehicle charging control method of claim 15 , further comprising:

registering, by the server, location information of the available second charging station with the charging station location information list, when a number of vehicles charged at the available second charging station is greater than or equal to a second threshold.

17 . The vehicle charging control method of claim 10 , wherein the state information of the first charging station includes information indicating that it is impossible to perform charging at the first charging station when the vehicle moves to a charging station different from the first charging station, after the vehicle arrives at the first charging station, when a destination or a waypoint is set to the first charging station.

18 . The vehicle charging control method of claim 10 , further comprising:

controlling, by the server, such that the first charging station is found by use of at least one of audio video navigation telematics (AVNT), telematics, an application, or a combination thereof, when it is determined that the first charging station is available; and

hiding, by the server, location information of the first charging station in a charging station location information list.
