According to one embodiment, the control unit 830 receives the usage amount of the battery 330 from the station 120, and can use it to determine the billing information. According to another embodiment, the controller 830 may calculate the amount of battery usage based on the difference between the first charge amount and the second charge amount, and use the calculated amount to determine the charge information. The control unit 830 can transmit accounting information to the bus company 140 and the station 120 to which the electric bus 110 belongs.

9 is a flowchart showing an operation method of the server 130 according to an embodiment.

Referring to FIG. 9, a method of operating the server 130 according to an embodiment may start with the controller 830 receiving power information from the station 120 in operation 911. Here, the power amount information may include at least one of identification information of the electric bus 110, identification information of the bus company 140 to which the electric bus 110 belongs, identification information of the station 120, .

Next, the control unit 830 can determine the billing information based on the usage amount of the battery 330 in the 915 operation. At this time, the control unit 830 can determine the billing information by comparing the usage amount of the battery 330 with the predetermined billing information. Here, the billing information corresponds to the charge of the battery 330 to the identification information of the electric bus 110, the identification information of the bus company 140 to which the electric bus 110 belongs, or the identification information of the station 120 And can be determined. The control unit 830 may transmit accounting information to at least one of the bus company 140 or the station 120 to which the electric bus 110 belongs in operation 917. [ Accordingly, the bus company 140 can charge the station company operating the station 120 for the usage amount of the battery 330 based on the billing information. On the other hand, the station company operating the station 120 can receive the charge for the amount of the battery 330 from the bus company 140 to which the electric bus 110 belongs based on the billing information. In this way, the method of operation of the server 130 according to one embodiment can be terminated.

10 is a flowchart showing an operation method of the server 130 according to another embodiment.

Referring to FIG. 10, the operation method of the server 130 according to another embodiment may start from the control unit 830 receiving the amount of power information from the station 120 in operation 1011. Here, the power amount information may include at least one of the identification information of the electric bus 110, the identification information of the bus company 140 to which the electric bus 110 belongs, the identification information of the station 120, . ≪ / RTI > Thereafter, the controller 830 can calculate the amount of use of the battery 330 in operation 1013. At this time, the controller 830 may calculate the usage amount of the battery 330 based on the difference value between the first charge amount and the second charge amount. That is, the controller 830 can calculate the remainder obtained by subtracting the second charged amount from the first charged amount as the used amount of the battery 330. [

Next, operations 1015 and 1017 in the method of operation of the server 130 according to another embodiment are similar to operations 915 and 917 in the method of operating the server 130 according to the above-described embodiment, do.

According to various embodiments, the system 100 may include a server 130 for controlling the electrical bus 110 and the station 120. The server 130 may detect the replacement of the battery 330 of the electric bus 110 at the station 120 and may determine the charging information based on the usage amount of the battery 330. [ Thus, the server 130 can determine the billing information corresponding to the electric bus 110 and the corresponding station 120. Thus, even though there are multiple companies for the electric bus 110 and a number of companies for the station 120, the charge for the amount of power used on the electric bus 110 can be efficiently charged.
