At this time, the mobile charging request information may be information including destination information of the electric vehicle user.

The mobile charging management server 100 extracts battery remaining amount information and vehicle position information from the mobile charging request information (S303), and based on the extracted battery remaining amount information and the vehicle position information, The predicted position is calculated (S305).

Meanwhile, the estimated discharge position may be calculated as a point on the estimated travel route to the destination of the electric vehicle to be charged, taking into account the destination information of the electric vehicle user.

The method for calculating the optimum contact point position according to the embodiment of the present invention is to provide a method of minimizing the time required to wait for the mobile charging vehicle of the charging electric vehicle user among the contacts capable of performing mobile charging.

First, the mobile charge management server 100 determines whether or not the chargeable electric vehicle and the mattress chargeable vehicle according to the contact possible positions, based on the position information of the electric vehicle to be charged, the position information of the mobile charged vehicle, (Step S401).

On the other hand, the estimated time may be more accurately calculated reflecting the road traffic situation information.

Next, the mobile charging management server 100 determines whether or not there is a contact-available position at which the mobile charging vehicle can arrive earlier than the charging target electric vehicle based on the estimated time required for the charging object electric vehicle and the estimated time required for the mobile charging vehicle (S403).

If the value obtained by subtracting the estimated time required for the mobile charging vehicle from the estimated time required for charging the electric vehicle to be charged is greater than zero (0) in the checking process in the step S403, The contact point can be identified as a contact point expected to arrive first. If the contact point is smaller than zero (0), the contact point can be identified as a contact point at which the mobile charged vehicle is expected to arrive later than the electric vehicle to be charged.

As a result of the checking in step S403, when there is a contact possible position that is expected to arrive at the mobile charging vehicle earlier than the electric vehicle to be charged, the mobile charging management server 100 determines the psychological anxiety due to the discharge of the electric vehicle user In order to minimize the contact point, the contact point at which the charging object electric vehicle can reach the earliest possible position, that is, the contact point with the shortest expected time for the electric charging object vehicle, can be calculated as the optimum contact point position at step S405.

In the step S403, the optimum contact point position can be more effectively calculated by performing the comparison of the expected time in the order of the contact possible positions located close to the electric vehicle to be charged.

Alternatively, if it is determined in step S403 that there is no contactable position that the mobile charging vehicle is expected to arrive earlier than the charging target electric vehicle, the mobile charging management server 100 determines that the charging target electric vehicle The waiting time of the electric vehicle to be charged for each possible contact position is calculated on the basis of the estimated time and the expected time of the mobile charged vehicle (S407).

The standby time means a time required for the electric vehicle to be charged to arrive at the contactable position first and wait for the arrival of the mobile charged vehicle. The waiting time is a value obtained by subtracting the estimated time required for the electric vehicle to be charged from the estimated time required for the mobile charged vehicle Can be calculated.

The mobile charge management server 100 can calculate the contact point having the shortest waiting time of the charging object electric vehicle among the contact possible positions to the optimum contact point position in order to minimize the time required for using the mobile charging service of the electric vehicle user (S409).

Meanwhile, when there are a plurality of contact possible positions having the shortest waiting time of the electric vehicle to be charged in the step S409, the mobile charging management server 100 determines whether or not the electric vehicle The contact point at which the electric vehicle to be charged can be reached as soon as possible, that is, the contact point of which the expected time for the electric vehicle to be charged is short, among the possible contact points, can be calculated as the optimum contact point position.

When the optimal contact point position is calculated through the above-described steps S401 to S409, the mobile charging management server 100 generates charging guide information including the charging optimum position information (S317) To the charging object electric vehicle and the mobile charging vehicle or the mobile charging vehicle management system (S319, S321).

Meanwhile, the mobile charging management server 100 related to the embodiment of the present invention may reduce the amount of remaining battery power based on the electric vehicle battery remaining amount information location information collected in real time in order to simplify a troublesome procedure for using the mobile charging service before step S301 If it is determined that there is no reachable charging station, a warning message may be transmitted to the electric vehicle, and a mobile charging service may be used.

5 is a flowchart illustrating a method for transmitting mobile charging notification information according to an embodiment of the present invention.

First, the mobile charging management server 100 of the present invention can collect emergency notification reference information including vehicle identification information, battery remaining amount information, and vehicle location information of an electric vehicle (S501).

The emergency notification reference information may be information including destination information of the electric vehicle user.

At this time, the information collection in step S501 may be performed on an electric vehicle of a user who has previously agreed to collect information.

The mobile charge management server 100 extracts battery remaining amount information and vehicle location information from the emergency notification reference information (S503).

Then, the mobile charging management server 100 determines whether there is a charging station that can reach the battery remaining amount based on the battery remaining amount information and the vehicle position information (S505).

The charging station location information necessary for confirming the step S505 may be derived from the database unit 150 of the mobile charging management server 100 that stores the location information.

As a result of the checking in step S505, if there is a charging station that can reach the battery remaining amount, the electric vehicle can be excluded from the emergency notification.

On the other hand, if it is determined in step S505 that there is no charging station that can reach the remaining battery level, the emergency notification procedure for the electric vehicle is performed.

At this time, the mobile charging management server 100 can further confirm whether or not it can reach the destination with the battery remaining amount by reflecting the destination information of the electric vehicle user, and if it is confirmed that the destination can not be reached with the battery remaining amount Only emergency cases can be processed.

The mobile charging management server 100 generates emergency notification information including a mobile charging service usage guidance message (S507), and transmits the emergency notification information to the corresponding electric vehicle (S509). The electric vehicle can receive and display the mobile charging service usage guidance message according to the emergency notification information in a user terminal such as a dedicated device, a navigation terminal, a vehicle driver's mobile phone, and the like.

Meanwhile, when the mobile charging request information is received from the electric vehicle that transmitted the emergency notification information, the mobile charging management server 100 calculates the mobile charging optimum contact position by using the same procedure as the above-described series of steps S301 to S321 Or a similar procedure may be performed.

At this time, the mobile charging request information transmission of the electric vehicle selects a mobile charging request button in accordance with a mobile charging service using information message displayed on a user terminal such as a dedicated device mounted on the vehicle, a navigation terminal or a vehicle driver's mobile phone It can be performed easily.

Hereinafter, the emergency notification procedure and the procedure for calculating the optimum contact point position will be described taking as an example the occurrence of a specific unexpected situation due to the battery discharge.
