[0063] In one embodiment, the user terminal 120 may, based on user input, request information indicating whether the battery pack 145 of the electric vehicle 140 is in a state where it can be evaluated for the issuance of a certificate, from the server 110 using the communication circuit 230. The processor 255 of the server 110 may determine, based on the request from the user terminal 120, whether the battery pack 145 is in a state where it can be evaluated for the issuance of a certificate. For example, the processor 255 of the server 110 may determine that the battery pack 145 is in a state where it can be evaluated if the electric vehicle 140 and the charging station 130 are connected to each other and the SOC of the battery pack 145 is equal to or lower than a specified SOC (e.g., 30%). However, the processor 255 of the server 110 may determine that the battery pack 145 is in a state where it cannot be evaluated if the electric vehicle 140 and the charging station 130 are not connected to each other or if the SOC exceeds a specified SOC (e.g., 30%). The communication circuitry 235 of the server 110 can then transmit to the user terminal 120 information indicating whether the battery pack 145 of the electric vehicle 140 is ready for evaluation for the issuance of a certificate.

[0064] In one embodiment, the user terminal 120 may receive, from the server 110, information indicating whether the battery pack 145 of the electric vehicle 140 is in a state where it can be evaluated for the issuance of a certificate, using the communication circuit 230. In one embodiment, the information indicating whether the evaluation is in a state where it can be evaluated may further include information regarding the SOC of the battery pack 145 of the electric vehicle 140 and whether the electric vehicle 140 and the charging station 130 can be connected.

[0065] In one embodiment, the user terminal 120 may select a preparation screen to be displayed from a first preparation screen or a second preparation screen based on information indicating whether evaluation is possible. The first preparation screen may guide the user to connect the electric vehicle to the charging station when the electric vehicle and the charging station are not connected to each other, and may guide the user that evaluation is possible when the SOC exceeds a designated SOC and is equal to or less than the designated SOC when the SOC exceeds a designated SOC. On the first preparation screen, an input button for evaluating the battery pack 145 may be inactivated. On the second preparation screen, an input button for evaluating the battery pack 145 may be activated.

[0066] In one embodiment, the user terminal 120 can select the first preparation screen if evaluation for the issuance of a certificate is not possible, and can select the second preparation screen if evaluation for the issuance of a certificate is possible.

[0067] In one embodiment, the user terminal 120 can display the selected preparation screen via the display 220 .

[0068] In one embodiment, the user terminal 120 may acquire a user input for an input button activated while the second preparation screen is displayed, where the user input may be understood as an input requesting evaluation of the battery pack 145.

[0069] In one embodiment, when the user terminal 120 receives a user input for the activated input button, the user terminal 120 may use the communication circuit 230 to send a first message to the server 110 requesting evaluation of the battery pack 145. In one embodiment, when the first message is sent, the user terminal 120 may change the second preparation screen to a progress screen, thereby causing the display 220 to display the progress screen.

[0070] The communication circuitry 235 of the server 110 may receive a first message from the user terminal 120. After receiving the first message, the processor 255 of the server 110 may evaluate the battery pack 145. In one embodiment, the evaluation of the battery pack 145 may be based on information (e.g., open circuit voltage (OCV), SoC, and state of health (SoH)) obtained while the battery pack 145 of the electric vehicle 140 is being charged. In one embodiment, the evaluation of the battery pack 145 may be based on an expiration date of the battery pack 145. In one embodiment, the evaluation of the battery pack 145 may be performed by comparing information of other battery packs of the same type as the battery pack 145 with information obtained while the battery pack 145 is being charged.

[0071] The communication circuitry 235 of the server 110 may transmit a second message indicating the result of the evaluation. The communication circuitry 230 of the user terminal 120 may receive a second message indicating the result of the evaluation from the server 110.

[0072] When the user terminal 120 receives the second message, the user terminal 120 can change the progress screen to a result screen, so that the display 220 can display the result screen.

[0073] In one embodiment, the user terminal 120 may acquire a user input via an activated input button while the result screen is displayed, where the user input may be understood as an input requesting the issuance of a certificate for the battery pack 145.

[0074] In one embodiment, when the user terminal 120 receives user input on the activated input button, it can use the communication circuit 230 to send a second message to the server 110 requesting the issuance of a certificate for the battery pack 145.

[0075] The communication circuitry 235 of the server 110 may receive a third message from the user terminal 120 requesting issuance of a certificate for the battery pack 145. After receiving the third message, the processor 255 of the server 110 may issue a certificate including an evaluation of the battery pack 145.
