Abstract

Disclosed are a system and method for managing an electric vehicle. The system includes: a vehicle state information collecting device collecting vehicle state information from one or more sensors; a terminal device receiving the vehicle state information from the vehicle state information collecting device and transmits the received information together with current position information and a vehicle ID for identifying the electric vehicle; and an electric vehicle managing device receiving and storing the vehicle state information for the vehicle ID, comparing the vehicle state information with a preset reference value of the information to determine whether to create a vehicle management message, and creating the vehicle management message that includes the place related to the vehicle state information or the position information of another electric vehicle on the basis of the current position information for the electric vehicle so as to transmit the message to the terminal device.

Claims

1. An electric vehicle management device, comprising:

a communication unit configured to

receive vehicle state information comprising at least one information selected from the group consisting of operation information of an electric vehicle, a vehicle identification (ID), current position information and destination information, from a terminal device, and

transmit a vehicle management message to the terminal device;

a vehicle state information database configured to store a reference value for determining whether or not to create the vehicle management message according to the vehicle state information;

an electric vehicle information database configured to store the ID, the vehicle state information, the destination information and the current position information of the electric vehicle;

a vehicle state determination unit configured to determine whether or not to create the vehicle management message by comparing the vehicle state information received through the communication unit with the reference value of the vehicle state information stored in the vehicle state information database;

an electric vehicle matching unit configured to match an electric vehicle configured to supply power and an electric vehicle configured to be supplied with the power according to power information, a current position and a destination of each electric vehicle; and

a vehicle management message creation unit configured to

create the vehicle management message including a place related to the vehicle state information, position information of other electric vehicles related to the vehicle state information, or a position of the electric vehicle configured to supply power and route information for moving to the corresponding electric vehicle, based on the current position information of the electric vehicle according to a result of the determination of the vehicle state determination unit, and

transmit the vehicle management message to the terminal device,

wherein the vehicle management message includes charging history of the electric vehicle which has supplied the power, and a reward for the electric vehicle according to the charging history, and

wherein the reward is discounted price when a price is charged for power at a charging station.

2. The device according to claim 1,

wherein the vehicle state information includes information on a battery remaining capacity, and

wherein, when the battery remaining capacity is lower than a battery remaining capacity set in the vehicle state information reference value:

the vehicle state determination unit is configured to determine a creation of the vehicle management message; and

the electric vehicle matching unit is configured to

search for position information of other electric vehicles are able to supply power within a reference distance based on the current position information of the electric vehicle, and

match the electric vehicle configured to supply power and the electric vehicle configured to be supplied with the power; and

the vehicle management message creation unit is configured to

create the vehicle management message including position information of an electric vehicle which is able to supply power, and

transmit the vehicle management message to the terminal device.

3. The device according to claim 1, wherein the vehicle management message further includes an amount of power to be provided when the power is charged and information on the charging station where power will be charged after supplying the power.

4. An electric vehicle management system, comprising:

a vehicle state information collecting device configured to collect vehicle state information from one or more sensors configured to sense the vehicle state information including battery power information related to operation of an electric vehicle;

a terminal device configured to

receive the vehicle state information from the vehicle state information collecting device, and

transmit the vehicle state information with current position information, destination information and a vehicle (ID) for identifying the electric vehicle; and

an electric vehicle management device configured to

receive the vehicle state information,

store the vehicle state information according to the vehicle ID,

determine whether or not to create a vehicle management message by comparing the vehicle state information with a previously set vehicle state information reference value,

create the vehicle management message including a place related to the vehicle state information or position information of other electric vehicles related to the vehicle state information based on the current position information of the electric vehicle, and

transmit the vehicle management message to the terminal device,

search for position information of other electric vehicles which are able to supply power within a reference distance based on the current position information of the electric vehicle,

match the electric vehicle configured to supply power and the electric vehicle configured to be supplied with the power,

create the vehicle management message including position information of an electric vehicle that can supply power according to a matching result, and

transmit the vehicle management message to the terminal device.

6. The system according to claim 4, wherein the vehicle management message further includes an amount of power to be provided when the power is charged and information on the charging station where power will be charged after supplying the power.

7. A control method of an electric vehicle management device, the method comprising:

receiving vehicle state information including battery power information related to operation of an electric vehicle, vehicle identification (ID), current position information and destination information, from a terminal device;

storing the vehicle state information by the vehicle ID and determining whether or not to create a vehicle management message by comparing the vehicle state information with a previously set vehicle state information reference value;

creating the vehicle management message including a place related to the vehicle state information or position information of other electric vehicles related to the vehicle state information based on the current position information of the electric vehicle according to a result of the determination of a vehicle state determination unit, and transmitting the vehicle management message to the terminal device;

collecting charging history of the electric vehicle which has supplied the power based on the vehicle management message; and

giving a reward according to the charging history, wherein the reward is discounted price when a price is charged for power at a charging station.

8. The method according to claim 7, wherein the vehicle management message further includes an amount of power to be provided when the power is charged and information on the charging station where power will be charged after supplying the power.

9. The method according to claim 7, wherein the storing comprises:

determining, when power of a battery is lower than a battery remaining capacity set in the reference value, the corresponding electric vehicle as an electric vehicle to be supplied with power; and
