Note that a specific signal can be used to determine that the electric vehicle charging station has stopped outputting power to the electric vehicle. It should be noted that, in some embodiments, when the electric vehicle notifies the electric vehicle charging station that the charging is stopped, the electric vehicle charging station can generate this specific signal and send it to the server. In some embodiments, when the electric vehicle does not receive power from the electric vehicle charging station for a predetermined period of time, the electric vehicle charging station can generate the specific signal and send it to the server. When the electric vehicle charging station does not stop outputting electric power to the electric vehicle (No in step S640), the process returns to step S630. When the electric vehicle charging station stops outputting power to the electric vehicle (Yes in step S640), as in step S650, the server then judges that the electric vehicle is charged within a preset time Whether the station has not re-exported power to the electric vehicle. Similarly, in some embodiments, the server can determine whether the electric vehicle charging station does not output power to the electric vehicle again within a predetermined period of time based on the charging data. When the electric vehicle charging station has re-output power to the electric vehicle within the preset time (No in step S650), as in step S660, the charging operation continues, and the server records a situation of the electric vehicle charging station output power within the preset time , and then the process returns to step S630. In some embodiments, the server further determines whether the electric vehicle charging station does not output power to the electric vehicle within a predetermined period of time, wherein the specified period is less than the predetermined time. When the electric vehicle charging station does not output power to the electric vehicle within a predetermined period of time, the server can calculate a delayed charging fee according to the specified period. It is reminded that when the specific period is longer than the preset time, the electric vehicle charging station generates a specific signal. When the specific period is not longer than the preset time, a delayed charging fee is generated. In other words, in this embodiment, when the electric vehicle is continuously coupled to the electric vehicle charging station but does not receive power from the electric vehicle charging station during the charging operation, the charge fee will be delayed. When the electric vehicle charging station does not output power to the electric vehicle again within the preset time (Yes in step S650), in step S670, the server sends a charging stop instruction to the electric vehicle charging station through the network to end the charging operation. After the charging operation is finished, as in step S680, the server calculates a charging fee for the corresponding charging operation according to the charging data and the output power of the electric vehicle charging station within a preset time. In some embodiments, when the electric vehicle charging station outputs power within the preset time, the non-charging time within the preset time can be obtained, and the charging fee of the non-charging time is set to 0 when the server calculates the charging fee. In some embodiments, when the aforementioned delayed charging fee is generated, the server adds the delayed charging fee to the charging fee.

As mentioned above, in some embodiments, the user can connect the electric vehicle to the electric vehicle charging station, such as inserting the charging gun into the charging interface of the electric vehicle, to send a charging request corresponding to the electric vehicle charging station. In some embodiments, the server can directly or indirectly receive a charging request from a mobile device of a corresponding electric vehicle owner. It is reminded that, in some implementations, the charging request may be accompanied by an identity authentication and/or a payment mechanism, and the charging authorization command/start charging instruction will not be generated until the identity authentication and/or payment mechanism is completed. In some embodiments, the user of the electric vehicle can use his mobile device to download and install an application, so as to generate a charging request through the user interface of the application. In some embodiments, the user can use the scanning function of the application to scan a two-dimensional identification code, such as a quick response code, on the electric vehicle charging station to generate the above-mentioned charging request. In some embodiments, the user can select a specific charging station through the application program, and execute an activation function to generate the above-mentioned charging request, thereby activating a charging procedure. In some embodiments, the electric vehicle owner can use a physical proximity card, such as an RFID proximity card, to approach a sensing area on the electric vehicle charging station to generate a corresponding charging request and send it to the server through the network. In step S704, corresponding to the charging request, the server sends a charging start instruction/charging authorization command to the electric vehicle charging station through the network, and the electric vehicle charging station performs a charging operation corresponding to the charging start instruction to output power to an electric vehicle. A vehicle, wherein the electric vehicle is electrically coupled to the electric vehicle charging station. Afterwards, in step S706, the server receives one of the charging data corresponding to the charging operation from the electric vehicle charging station through the network. As mentioned above, when the electric vehicle is coupled to the electric vehicle charging station through the charging cable of the electric vehicle charging station for charging operation, the electric vehicle charging station can continuously transmit the charging data of the corresponding electric vehicle charging operation through the network , the server can receive the charging data of the corresponding charging operation from the electric vehicle charging station through the network. In some embodiments, the charging information may include the state of charge of the corresponding electric vehicle, the elapsed time of the charging operation, the The amount of electricity received during the charging operation, the electricity output from the electric vehicle charging station to the electric vehicle, etc. Next, in step S708, the server determines whether the electric vehicle charging station stops outputting power to the electric vehicle. As mentioned above, in some embodiments, the server can determine whether the electric vehicle charging station stops outputting power to the electric vehicle through the charging data. It should be noted that, in some embodiments, the server determines whether a specific signal is received from the electric vehicle charging station through the network. Note that a specific signal can be used to determine that the electric vehicle charging station has stopped outputting power to the electric vehicle. It should be noted that, in some embodiments, when the electric vehicle notifies the electric vehicle charging station that the charging is stopped, the electric vehicle charging station can generate this specific signal and send it to the server. In some embodiments, when the electric vehicle does not receive power from the electric vehicle charging station for a predetermined period of time, the electric vehicle charging station can generate the specific signal and send it to the server. When the electric vehicle charging station does not stop outputting electric power to the electric vehicle (No in step S708), the process returns to step S706. When the electric vehicle charging station stops outputting power to the electric vehicle (Yes in step S708 ), in step S710 , the server then determines whether the electric vehicle charging station does not output power to the electric vehicle again within a predetermined period of time. Similarly, the server can determine whether the electric vehicle charging station has not output power to the electric vehicle again within a predetermined period of time based on the charging data. When the electric vehicle charging station has re-output electric power to the electric vehicle within the preset time (No in step S710), the process returns to step S706. When the electric vehicle charging station does not output power to the electric vehicle again within the preset time (Yes in step S710 ), in step S712 , the server sends a charging stop instruction to the electric vehicle charging station through the network to end the charging operation. After the charging operation is finished, in step S714, the server determines whether the electric vehicle charging station has stopped being electrically coupled to the electric vehicle. When the electric vehicle charging station has not stopped being electrically coupled to the electric vehicle (No in step S714 ), in step S716 , the server calculates an occupancy fee. As a reminder, in some embodiments, occupancy fees may vary over time. Afterwards, the judgment of step S714 is continued. When the electric vehicle charging station has stopped being electrically coupled with the electric vehicle (Yes in step S714 ), in step S718 , the server calculates the charging fee for the corresponding charging operation according to the charging data and the occupation fee. In other words, the occupancy fee is added to the charging fee.

In some embodiments, in step S710, when the server determines that the electric vehicle charging station re-outputs power to the electric vehicle within a preset time, the server does not send a message to the mobile device. After the charging operation is finished, the server sends a message to the mobile device through the network to notify that the charging operation has been completed. In other words, when the electric vehicle charging station stops outputting power to the electric vehicle and re-outputs power to the electric vehicle within a preset time, it means that the charging operation has not been completed, and the server will not send a message to the mobile device, and when the charging operation is completed , the server will send the message to the mobile device. In some embodiments, the server receives one of the charging data corresponding to the charging operation from the electric vehicle charging station through the network. When the charging operation starts, the server sends a link to the mobile device through the network, wherein the mobile device can connect to the server through the link to view the charging data of the corresponding charging operation.
