Here, the user terminal 10 may include a smartphone, tablet, PC, and navigation system installed in an electric vehicle.

In step S160, the user terminal 10 may request a charging service reservation from the charging service providing system 100.

In step S170, the charging service providing system 100 may generate reservation information and transmit the generated reservation information to the mobile power storage device 20. The charging service providing system 100 may generate reservation information based on charging service information generated when a reservation request is received. The reservation information may include at least one of the following: identification information of the electric vehicle, identification information of a charging hotspot where charging service is available, location, charging amount, waiting time, charging fee, or charging time.

Additionally, the charging service providing system 100 may generate reservation change information for a reservation request from an offline reservation holder (non-reservation person). Offline reservations are those who visit a charging hotspot directly and request a reservation. At this time, the charging service providing system 100 may request the offline reservation holder whether the offline reservation holder approves priority charging by providing reservation change information. Here, the charging service providing system 100 may provide compensation according to priority charging of offline reservation holders to advance reservation holders.

Additionally, the charging service providing system 100 may deploy a mobile power storage device 20. The charging service providing system 100 may move the portable energy storage device 20 based on reservation information. As an example, the charging service providing system 100 can predict charging demand and deploy the mobile energy storage device 20 by reflecting the operation information of the charging hotspot. Here, the operation information of the charging hotspot may include at least one of the number of electric vehicles using the charging service, remaining charge amount, number of reservations, etc. depending on the day/time. In addition, the charging service providing system 100 can perform additional placement and movement of the mobile energy storage device 20 by monitoring real-time reservation status.

In step S180, the charging service providing system 100 may store information about providing an electric vehicle charging service. As an example, the charging service providing system 100 may store information transmitted and received between the user terminal 10 and the mobile energy storage device 20. Additionally, the charging service providing system 100 can store charging service information, reservation information, and charging hotspot operation information and update them in real time. The charging service providing system 100 is able to provide a more accurate charging service by continuously updating the reservation status for each charging hotspot.

Figure 6 is a diagram illustrating a method for generating charging service information by a charging service providing system according to an embodiment of the present invention.

In step S141, the charging service providing system may calculate the waiting time based on the remaining chargers and reservation status information for each charging hotspot. The reservation status may include the number of reservation users at the corresponding charging hotspot, the sum of reservation usage times, and the degree of charging progress by reservation users. Since the charging service provision system is based on information updated in real time, the waiting time can be calculated and updated in real time.

In step S142, the charging service providing system may calculate the charging time according to the charging demand and charging speed. First, the charging service providing system can calculate charging demand based on battery information. The charging demand is the current battery amount subtracted from the amount that can fully charge the battery. The charging service provision system can calculate the charging time using the calculated charging demand and the charging speed for each charging hotspot.

In step S143, the charging service providing system may calculate the charging fee based on a combination of charging demand, remaining chargers for each hotspot, discount/surcharge, whether the mobile ESS is moved, and whether the reservation can be changed. The charging service provision system can automatically calculate charging fees for each charging hotspot customized to the user based on data collected and analyzed in real time.

In step S144, the charging service providing system may generate charging service information for each charging hotspot by considering the user's total available waiting time. The charging service provision system can compare the user's total available waiting time and the sum of the calculated waiting time and charging time. As an example, if the user's total available waiting time is greater than the sum of the calculated waiting time and charging time, the charging service providing system may generate charging service information for the corresponding charging hotspot. Charging service information may include at least one of the following: identification information for each charging hotspot, location, charging amount, waiting time, charging fee, or charging time.

According to the method of providing an electric vehicle charging service according to an embodiment of the present invention, a charging hotspot can be operated according to charging demand. Charging hotspots can be relocated and installed when and where needed. Accordingly, there is an effect of providing electric vehicle charging services to users even when charging demand for electric vehicles increases rapidly in a specific region at a certain time and the fixed charging station alone cannot meet the charging demand for electric vehicles.
