After the charge request is received through the charge request acceptance step S11, a charge reservation availability checking step S21 is performed.

In the charge reservation availability checking step (S21), it is confirmed through the charge request acceptance step (S11) whether the charge reservation is possible for the electric vehicle for which the charge request has been received. In the charging reservation availability checking step (S21), the control unit 250 requests the usage data for the charging station provided in the charging station from the charging station usage database 210, and includes the reservation status provided from the charging station usage database 210. From the usage data for the charging station, the available time is compared with the scheduled time to visit the charging station included in the driver's charging request message to determine whether or not charging is possible. When it is confirmed in step S21 whether the reservation for charging is possible, the reservation acceptance step (S31) is performed when it is determined that the driver can make a reservation for charging at a desired time, and when it is determined that the reservation for charging is not possible at the desired time A step (S41) of checking whether a replaceable battery is present is performed.

The reservation acceptance step (S31) is performed when it is confirmed in the charging check whether the reservation is possible at the battery charging station at a time desired by the driver (S21). In the reservation acceptance step (S31), the driver's charging request is received by the control unit 250, and the control unit 250 transmits a reservation confirmation message to the driver through the communication unit 230. The reservation confirmation message sent to the driver includes the charging reservation time and the location (number) of the reserved charging station. The charging reservation information received through the reservation acceptance step S31 is stored in the charging station usage database 110 by the control unit 250.

The presence or absence of the replacement battery inventory checking step S41 is performed when it is determined in the charging reservation availability checking step S21 that it is not possible to reserve the charging at the battery charging station at a time desired by the driver. In the step (S41) of checking whether there is a replacement battery inventory, it is checked whether the replacement battery inventory remains. The presence or absence of the replacement stock (S41) is performed by checking the real-time inventory of the replacement battery remaining in the battery charging station from the replacement battery database 220 by the control unit 250. When it is determined in the battery charging station that the replacement battery inventory exists (S41), the replacement guide step (S51) is performed, and when it is determined that the replacement battery is not in stock, A step (S61) of checking whether a replacement battery can be delivered is performed.

The replaceable guide step (S51) is performed when it is confirmed that the replaceable battery stock is present in the battery charging station in the presence of replaceable battery stock (S41). In the replaceable guide step (S51), the control unit 250 transmits a charging station replacement guide message informing the driver of the electric vehicle through the communication unit 230 that a replaceable battery can be replaced at a charging station, and whether the battery is replaced together. To the driver. If it is determined that the driver wishes to replace the battery, a battery replacement service is reserved.

The step of checking whether a replaceable battery can be delivered (S61) is performed when it is confirmed that there is no replaceable battery stock at a battery charging station in a step (S41) of checking whether a replaceable battery is present. In the step S61 of checking whether delivery of the replacement battery is possible, the control unit 250 determines whether it is possible to immediately deliver the replacement battery to a driver at a place other than the battery charging station. Specifically, the step (S61) of checking whether a replaceable battery can be delivered is performed by checking the real-time inventory of the replaceable battery remaining in a place other than the battery charging station from the replaceable battery database 220 by the control unit 250. If it is determined that the replacement battery is in stock outside of the battery charging station, it is determined that delivery of the replacement battery is possible, and the delivery information guide step (S71) is performed, and that the replacement battery is not in stock outside the battery charging station. If it is confirmed, it is determined that delivery of the replaceable battery is impossible and the service is terminated.

The delivery information guide step (S71) is performed when it is determined that delivery of the replaceable battery is possible in the check whether the replaceable battery can be delivered (S61). In the delivery information guiding step (S71), a message informing the delivery location and cost of the replacement battery selected and calculated by the control unit 250 is transmitted to the driver through the communication unit 230. Although not shown, in order to select a more suitable delivery place and calculate an accurate cost in the delivery information guide step S71, the controller 250 may be provided with information on a movement route from a driver to a current location or a destination. The controller 250 selects a suitable delivery location based on the current location or the route information to the destination provided by the driver, and calculates the cost used for delivery. In the delivery information guide step (S71), a case based on a minimum delivery time and a case based on a minimum delivery cost may be guided to the driver, respectively, and a selection may be requested from the driver. After the delivery information is transmitted to the driver by the delivery information guide step S71, a delivery request acceptance confirmation step S81 is performed.

In the delivery request acceptance confirmation step (S81), it is checked whether the delivery request is received from the driver through the communication unit 230 by the control unit 250. The delivery request data, which is received and confirmed in the delivery request acceptance confirmation step (S81), includes delivery method information selected by the driver. If the driver's delivery request is confirmed in the delivery request acceptance confirmation step S81, the delivery instruction step S91 is performed, and if the driver's delivery request is not confirmed, the service is terminated.

In the delivery instruction step S91, delivery to the replaceable battery is indicated. The delivery instruction step S91 is performed by the control unit 250 transmitting a delivery instruction message to the terminal of the delivery person through the communication unit 230. Delivery to the replacement battery may be delivered to a delivery location using various delivery means including drones.
