DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the present specification, 'EV' is abbreviated as 'Electric Vehicle' and 'EVSE' is abbreviated as Electric Vehicle Supply Equipment. The EVSE provides functions such as charging status monitoring, vehicle authentication, vehicle information confirmation, and billing, as well as providing a stable power supply for electric vehicle charging.

These embodiments are directed to a method of updating a charging application for charging an electric vehicle and can be applied to an electric charging system for an electric vehicle.

Recently, there are cases where the charge protocol version is not the same depending on the state of the charging infrastructure installed in each country, and various products produced by EV and EVSE manufacturers. In addition, a new charging protocol may be created due to the continual revision of the EV-EVSE charging related standard. In particular, updating the charging protocol version of an already sold EV or EVSE installed in each region may not be practically possible.

In consideration of these problems, in the present invention, when the EV-EVSE charging protocol version and the charging procedure are different at the charging process of the EV and the EVSE, the charging protocol version and the charging procedure of the EV-EVSE may be updated so that the normal charging is performed.

As shown in Figs. 1 and 2, a pair of charging applications composed of an EV charging application and an EVSE charging application corresponding to the charging protocol version of the EV can be mounted on the EV. Likewise, the EVSE can also be equipped with a charging application for the EV and a pair of charging applications for the EVSE charging application corresponding to their charging protocol version.

According to the present invention, the EV and the EVSE transmit / receive an acknowledgment / response message to check the charging protocol version and whether charging is possible. At this time, if there is a difference in version between the EV and the EVSE, as shown in FIG. 1, the EV transmits the EVSE charging application to the EVSE to update the EVSE charging application can do. As shown in Fig. 2, the EVSE can update the charge application for EV on the EV side by transferring the charge application for EV that the EVSE has to the EV side. Through this process, the EV and the EVSE can be updated to the same charging protocol version so that normal charging can be performed.

3 illustrates a message sequence process for updating an EVSE charging application, in accordance with an embodiment of the present invention.

First, when a plug is connected between the EV and the EVSE (S301), the EV sends a request message (Request Message) about the charging protocol version and the charging availability to the EVSE side (S302) A response message is transmitted (S303). The confirmation message of the charging protocol version and rechargeability may include ProtocolNamespace, VersionNumberMajor, VersionNumberMinor, SchemaID, Priority, and the response message to the charging protocol version and rechargeability may include ResponseCode and SchemaID.

At this time, if the charging protocol version of the EV is different from that of the EVSE, the EV transmits the EVSE charging application that it owns to the EVSE side (S304). Accordingly, the EVSE side updates the EVSE charging application received from the EV to the EVSE charging application (S305), and transmits an update completion message to the EV side when the updating is completed.

Thereafter, the EV transmits a confirmation message to the EVSE side regarding the charging protocol version and the charging availability (S306), and the EVSE transmits a charging protocol version and a charging response message to the EV side (S307). If the charging protocol version of the EV and the EVSE are the same according to the updating of the charging application, the charging process of the EV and the EVSE proceeds.

4 illustrates a message sequence process for updating an EV charging application, in accordance with an embodiment of the present invention.

First, when a plug is connected between the EV and the EVSE (S401), the EV transmits a confirmation message about the charging protocol version and the charging availability to the EVSE side (S402), and the EVSE transmits a charging protocol version and a response Message (S403).

At this time, if the charging protocol version of the EV is different from that of the EVSE, the EVSE transmits the charging application for the EV that it has to the EV side (S404). Accordingly, the EV side updates its own charging application for EV to the EV charging application received from the EVSE (S405), and transmits an update complete message to the EVSE side when the updating is completed.

Thereafter, the EV transmits a confirmation message about the charging protocol version and the charging availability to the EVSE side (S406), and the EVSE transmits a charging protocol version and a charging response message to the EV side (S407). If the charging protocol version of the EV and the EVSE are the same according to the updating of the charging application, the charging process of the EV and the EVSE proceeds.

EV side operation

If the EV is connected to the EVSE (S511), the EV transmits a confirmation message to the EVSE regarding the charging protocol version and the charging availability (S512).

Thereafter, when the EV message is received from the EVSE (S513), the EV compares the charging protocol version of the charging application of the EVSE with the charging application of the EVSE (S514).

At this time, if the charging application version of the charging application of the EVSE matches the charging application of the EV, the EV can proceed normal charging with the EVSE (S515).

Meanwhile, if the charging application version of the charging application of the EVSE is different from the charging application of the EVSE, the EV transmits the charging application for the EVSE to the EVSE (S516).

Thereafter, when the update completion message for the EVSE charging application is received from the EVSE side (S517), the EV repeatedly checks the charging protocol version while repeating the above-described steps (S512 to S514), and determines whether to proceed with the charging.

EVSE side operation

After the EV is connected to the plug (S521), the EVSE receives a confirmation message of the charging protocol version and charging availability from the EV (S522), and transmits a charging protocol version and a response message indicating whether charging is possible to the EV ).

At this time, the EVSE compares the charging application version of the charging application that the EV has with the charging application version of the charging application that the EV has (S524). If the charging application matches the charging application version of the charging application that the EV has, Normal charging can proceed (S525).

On the other hand, when the charging application version of the charging application that the EV has is different from the charging application that the EV has, the EVSE receives the EVSE charging application that the EV has from the EV (S526).

At this time, the EVSE updates the EVSE charging application received from the EV to the EVSE charging application, and transmits an update completion message for the EVSE charging application to the EV when the updating is completed (S527).

Thereafter, the EVSE repeats the above-described steps S522 to S524, and once again confirms the charging protocol version, and then determines whether to proceed with the charging.

EV side operation

After the EV is connected to the EVSE (S611), the EV transmits a confirmation message to the EVSE about the charging protocol version and the charging availability (S612).

Thereafter, when the EV message is received from the EVSE (S613), the EV compares the charging application stored in the EVSE with the charging protocol version of the charging application stored in the EVSE (S614).

At this time, if the charging application version of the charging application of the EVSE matches the charging application of the EV, the EV can proceed normal charging with the EVSE (S615).

Meanwhile, if the charging application version of the charging application that the EVSE has is different from the charging application that the EV has, the EV receives the charging application for the EV that the EVSE has from the EVSE (S616).

At this time, the EV updates the EV charging application received from the EVSE, and transmits an update completion message for the EV charging application to the EVSE (S617).

After repeating the above steps (S612 to S614), the EV may check the charging protocol version again and determine whether to proceed with charging.

EVSE side operation

After the EV is plugged with the plug (S621), the EVSE receives a confirmation message of the charging protocol version and charging availability from the EV (S622), and transmits a charging protocol version and a response message indicating whether or not charging is possible to the EV (S623 ).

At this time, the EVSE compares the charging application version of the charging application of the EV with the charging application version of the charging application of the EV (S624). If the charging application of the charging application of the EV matches the charging application version of the charging application of the EV, Normal charging can proceed (S625).

If the charging application version of the charging application that the EV possesses is different from the charging application that the EV has, the EVSE transmits the charging application for the EV to the EV (S626).

Thereafter, when the EVSE receives the update completion message for the EV charging application from the EV side (S627), the EVSE repeats the above-described steps (S622 to S624), confirms the charging protocol version again, and determines whether to proceed with charging.
