As described above, the charging station is searched by using the energy price information or the designated charging area information designated by the user of the electric vehicle, so that the server can provide the terminal or the user of the electric car with more reliable information about the charging station.

Referring to FIGS. 10, 11, and 13, conditions for providing the electric energy prices by time of charging station to the terminal of the electric vehicle will be described by the server. Each time the server receives the vehicle operation message from the terminal of the electric vehicle, the server can provide the electric energy prices of the selected at least one charging station to the terminal of the electric car. For example, step 1020, step 1117 or step 1120 may be omitted.

As a result of the determination in step 1117, if the field indicating whether or not to request the charging station information included in the vehicle operation message indicates the charging station information request, the server stores the electric energy prices of the selected at least one charging station, .

As a result of the determination in step 1020 or 1120, if the number of the charging stations searched after receiving the vehicle operation message is smaller than the threshold value, the server determines the time of at least one charging station Electric energy prices can be selected by category. For example, when the vehicle operation message including the position information and the battery level is transmitted periodically or from a terminal of the electric car to the server on a predetermined event basis, and the electric car moves from the position A 1301 to the position F 1306 . When the terminal of the electric car transmits the vehicle operation message at the position E (1305) before reaching the movable distance 1321, the server judges that the number of the found charging stations is smaller than the threshold value (for example, 3) (1345) and the charging station (1347).

In addition, when the battery level of the electric vehicle included in the vehicle operation message received from the terminal of the electric vehicle is equal to or lower than a preset level, the server can search electric energy prices by time of the at least one charging station to be provided to the terminal of the electric vehicle. That is, when the battery level of the electric vehicle is greater than a predetermined level, the server may not perform the process for searching for the charging station.

Further, the server may search for charging stations located at a time (or a time zone) or a range corresponding to the position (or area) satisfying at least one of the conditions for providing the electric energy prices by the charging station in the above-described charging station, And provide the electric energy prices for the selected charging stations to the terminal of the electric car. For example, the location information included in the vehicle operation message indicates location A 1301, and the area 1335 corresponding to the charging area information designated by the user may include charging station 1345 and charging station 1347 . In addition, a field indicating whether or not the charging station information request included in the vehicle operation message is requested may indicate the charging station information request. At this time, the server limits the search range of the charging station to the charging station located within the movable distance 1321 of the electric vehicle from the moving distance 1322 when the battery level of the electric vehicle is less than a preset level (for example, 15% of the total charging capacity) can do. The server can provide information on the charging station 1345 and the charging station 1347 to the terminal of the electric car in advance (time information of the electric energy prices or location information of the charging station). In addition, the server calculates an expected time for reaching the charging station 1345 and the charging station 1347, and preferentially provides the electric energy price for the charging stations corresponding to the reachable time zone including the estimated time after the current time can do. In addition, the server may further provide information on the charging station 1343 and the charging station 1341. [ Further, the server can additionally provide information about the charging station located around the location A 1301 corresponding to the current location of the electric vehicle. Depending on the side, the server can selectively determine the search range according to the information contained in the vehicle operation message (for example, information indicating whether to search based on the current position or not, have. Accordingly, the terminal of the electric vehicle can receive the information of the charging station more conveniently according to the information.

12 is a flowchart illustrating a method of operating a charging system of a terminal of an electric vehicle according to an embodiment of the present invention.

The terminal of the electric vehicle can transmit the vehicle operation message including the location information to the server. The terminal of the electric vehicle can receive electric energy prices by time of the at least one charging station from the server in response to the vehicle operation message. The terminal of the electric vehicle can transmit to the server a purchase reservation message including at least one charging station to which energy is to be supplied and time information of energy to be supplied. The terminal of the electric vehicle can receive the purchase confirmation message from the server in response to the purchase reservation message.

In step 1205, the terminal of the electric vehicle may acquire the vehicle operation information including the position information and / or the battery level. The vehicle operation information may include energy price information designated by the user of the electric vehicle, specified time period information, designated charging area information, moving destination of the electric vehicle, or moving direction of the electric vehicle.

In step 1210, the terminal of the electric vehicle may determine whether it has received a charging station information request from the user. If the charging station information request is not received, the terminal of the electric vehicle may enter the step 1220. [ In addition, the field value indicating whether the charging station information request is included in the vehicle operation message can be set so as not to indicate the information request.

If the terminal of the electric car receives the charging station information request from the user, it may set the field value indicating whether the charging station information is included in the vehicle operation message to indicate the information request in step 1215.

In step 1220, the terminal of the electric vehicle may transmit a vehicle operation message. The vehicle operation information may include energy price information designated by the user of the electric vehicle, information of designated time zone, designated charging area information, moving destination of the electric car, moving direction of the electric car, or a field value indicating whether charging station information is requested.

In step 1225, the terminal of the electric vehicle may receive the electric energy prices by time of the at least one charging station from the server in response to the vehicle operation message. At this time, the terminal of the electric car can provide the received information to the user of the electric car. Table 2 below shows examples of electric energy prices of at least one charging station provided by the terminal of the electric vehicle to the user of the electric vehicle by time.

For example, the information provided to the user may include charging stations S_a 1345 and S_b 1347 belonging to the area 1335 of FIG. 13 corresponding to the charging area information designated by the user. Further, the information provided to the user may include a time zone from 13:00 to 18:00 and a time zone from 18:00 to 21:00, in consideration of the time zone specified by the user or the time zone in which the electric vehicle can be reached. In addition, it may further include a time zone including the current time or a predetermined time zone after the current time zone. For example, the current time period and the 24 hour time period after the current time may be included.

The terminal of the electric vehicle can provide the user of the electric vehicle with the plug-in method of charging the battery of the electric car between the cities and the electric energy prices of the battery exchange type in which the battery of the charging station battery and the electric car are exchanged. For example, when the electric vehicle moves from the position A 1301 to the position F 1306, the charging stations S_a 1345 and S_b 1347 considering the charging stations or movable distances around the current position A 1301 Information can be received. Accordingly, the user of the electric vehicle can confirm the information on the position information of the S_a 1345 and the S_b 1347 or the movable distance, and confirm the amount of electric energy required to reach the destination F 1306. [ The amount of electric energy required to reach the destination may be calculated by the terminal of the server or electric car, and may be provided to the user of the electric car. At this time, the amount of electric energy required may be an amount that can be charged in a suitable time such that the user of the electric car does not feel inconvenience when supplied with a plug-in method that is less expensive than the battery exchange method. In addition, the user of the electric vehicle may not want to receive energy in the path after position B 1302. [ Accordingly, the user of the electric vehicle can confirm the prices of the electric energy of the plug-in type among the information of the charging station located around the location A 1301, and can select the charging station to receive the energy through the terminal of the electric car. Also, according to the user's selection, the electric vehicle can be supplied with energy through a battery exchange system through one of the charging stations S_a 1345 and S_b 1347. [

Also, when the charging area information designated for the city area from 13:00 to 18:00 is given to the terminal of the electric car so as to be provided to the user in advance, the electric energy prices of S_a 1345 and S_b 1347 are set to the electric energy of S_c 1341 May be provided in preference to prices. In addition, when the terminal is set to the terminal of the electric car so as to give priority to the lower price or the price information designated by the user for the city area from 18:00 to 21:00, a charging station having a low electric energy price can be given priority.

According to one aspect, the terminal of the electric car firstly transmits the classification standard of the information about the charging station to be provided to the server using the vehicle operation message, and the server searches and / or selects the information according to the classification criteria of the information, Can be separately transmitted. For example, when the vehicle operation message transmitted in step 1220 includes the energy price information designated by the user, the electric energy prices of the at least one charging station received from the terminal of the electric vehicle at the time of the charging period, And can have an energy price equal to or less than the corresponding price. For example, when the vehicle operation message transmitted in step 1220 includes the time zone information designated by the user, the electric energy prices of the at least one charging station received from the terminal of the electric vehicle by the terminal are stored in the designated time period And may include hourly electrical energy prices corresponding to the information. For example, when the vehicle operation message transmitted in step 1220 includes the charging area information designated by the user, at least one charging station received from the server of the terminal of the electric car is included in the area corresponding to the charging area information And may include at least one charging station.

In addition, when the terminal of the electric car receives the information on the charging station without prioritizing information from the server, the terminal may distinguish or prioritize the information to be provided in the received information and provide it to the user.

In step 1230, the terminal of the electric vehicle can automatically acquire the charging station to which the energy is supplied and the time interval information to be supplied with energy from the received at least one charging station through the control unit of the terminal of the electric vehicle, or acquire it from the user .

In step 1235, the terminal of the electric vehicle may transmit to the server a purchase reservation message including at least one charging station to which energy is to be supplied and / or time information to be supplied with energy.

In step 1240, the terminal of the electric vehicle may receive a purchase confirmation message from the server in response to the purchase reservation message.

Also, the terminal of the electric vehicle can receive the charging history information including information on the charging station to receive energy from the server. Here, the charge history information may include electric energy prices by time zone of a specific area.

In addition, the terminal of the electric car can receive electric energy prices by time zone of a specific area. The terminal of the electric vehicle can generate reference prices by time zone based on electric energy prices by time zone of a specific area. The price of at least one of the reference prices may be set as the electric energy price information designated by the user to be included in the vehicle operation message.
