Description

{ELECTRIC VEHICLES CHARGING SYSTEM}

The present invention relates to an electric vehicle charging system which can charge an electric vehicle at an electric vehicle charging power rate of an electric power company even with an inexpensive emergency charger having only a charging function, by easily installing a dedicated outlet anywhere using existing wiring without dedicated wiring work, thereby expecting expansion of electric vehicle charging infrastructure using a dedicated outlet as a charging station, and by constructing it in conjunction with a mobile payment system (or mobile pay system), the system construction is also easy, and can contribute to diversification of mobile payment services.

Chargers that can charge electric vehicles at the electric vehicle charging power rate of the electric power company are classified into standing chargers that are shared and personal chargers that are owned by individuals.

Here, standing chargers can be subdivided into partially open slow chargers and partially open rapid chargers, but either one must have a charging system built in, be connected to a dedicated line, be separately metered, and be subject to the charging business operator's rates, so the installation costs, operating costs, and previous installation costs are high, and a dedicated installation space is also required, and the installation location is also restricted.

Personal chargers are divided into fixed chargers and mobile chargers. Here, fixed chargers are connected to a dedicated line and must be measured separately, so they require high installation and relocation costs, and in reality, they cannot be used by an unspecified number of people.

Accordingly, a portable charger that can be charged through a dedicated outlet has been developed and commercialized.

Mobile chargers charge through an outlet like emergency chargers, but they are equipped with a power meter, a communication module for public communication network connection, and a tag reader (or short-range communication module). They can recognize a dedicated capacitor to allow charging, measure themselves when charging, and transmit the measured power amount to pay the electric vehicle charging fee. Accordingly, when using a mobile charger, you can apply the electric vehicle charging power rate of the power company like other types of chargers. However, mobile chargers are more expensive than emergency chargers, so their spread has not lived up to expectations.

In addition, since the outlets designated exclusively for the use of portable chargers are general outlets that can be used by anyone, there are still concerns about challenges, and accordingly, the number of designated dedicated outlets has not increased as much as expected.

In addition, when using a mobile charger, a separate payment system had to be built, which increased the cost of building the system and made it inconvenient for electric vehicle drivers to use the service.

Therefore, rather than supplying as many mobile chargers as the number of electric vehicles, it is desirable to install dedicated outlets that can be significantly less than the number of electric vehicles, but installed so that they can be used as public ones, so that an unspecified number of people can charge anywhere and at any time using inexpensive emergency chargers. However, this could not be done with existing personal mobile chargers and personal fixed chargers.

Moreover, as the recent trend is to make it mandatory to install electric vehicle charging facilities in parking lots with a certain number of spaces or more, there is an even greater need for dedicated electric vehicle charging outlets that are inexpensive, easy to install, and easy to expand.

KR 10-2016-0012355 A 2016.02.03. KR 10-1828593 B1 2018.02.06. KR 10-2015-0129970 A 2015.11.23.

Accordingly, the purpose of the present invention is to provide an electric vehicle charging system that can charge at the electric power company's electric vehicle charging power rate anytime and anywhere by using an inexpensive emergency charger that can be charged by connecting to an outlet, and can apply an electric power rate deducted by the amount of charging power to a user where an outlet is installed, and can also install and operate a dedicated outlet at a low cost in a location where a general outlet is installed, and guarantee payment even if an unspecified number of people use it by linking with an existing mobile payment system without constructing a separate payment system, and can prevent challenges at the source.

In order to achieve the above object, the present invention provides an electric vehicle charging system that enables charging of an electric vehicle (1) by using a cable-type emergency charger (10) connecting an outlet connected to a commercial power source and a charging port (2) of an electric vehicle (1) after requesting payment of a charging fee using a smart phone (20) having a mobile payment app installed that requests payment by tagging a tag, the system comprising: an outlet (100) configured to supply commercial electricity with a plug that is connected to a commercial power source, measure the amount of supplied electricity, and control the supply of commercial electricity; an outlet tag (200) installed at or around the outlet (100) and having an outlet identification code recorded thereon so as to identify the outlet (100); A mobile bank server (300) that manages members registered with a mobile payment app, transmits to a remote management server (400) a member who requests payment by tagging an outlet tag (200) with a smartphone (20) and an outlet identification code obtained by tagging as party information, requests charging and records and manages the charging start list, records and manages the party information and power rate received from the remote management server (400) upon charging completion in the charging completion list, processes payment to the power company according to a pre-determined member payment method, and deletes the party information upon charging completion from the charging start list; A remote management server (400) is provided, in which an outlet identification code, an installation location of an outlet (100), and an electric power company power meter identification code of a user in which an outlet (100) is installed are stored so as to be matched with each other, and remotely controls an outlet (100) identified by an outlet identification code of the party information transmitted in response to a charging request from the mobile bank server (300) to supply commercial electricity, receives the supplied power amount upon completion of charging, calculates a power rate, transmits the power rate together with the party information to the mobile bank server (300), notifies completion of charging, and transmits the supplied power amount to the electric power company server (700) to request deduction from the power consumption of the user in which the outlet (100) is installed.

The above outlet (100) is equipped with a plug detection unit (123) that detects whether the plug (12) is removed, and when the removal of the plug (12) is detected during power supply for charging, the power supply is stopped to stop charging, and the removal of the plug (12) is notified to the remote management server (400). The remote management server (400) calculates the power rate based on the amount of power supplied up to the point when the plug (12) was removed, and transmits the result to the mobile bank server (300) for payment processing.

The emergency charger (10) is further configured to include a charger tag (210) installed in the plug (12) of the emergency charger (10) and used to record a charger identification code to be used for identifying the emergency charger (10), and the outlet (100) is equipped with a tag reader (160) for tagging the charger tag (210), and the remote management server (400) stores the charger identification code of the installed charger tag (210), receives the charger identification code read by the tag reader (160) of the outlet device (100) identified by the outlet identification code of the party information, and remotely controls the outlet (100) to supply commercial electricity only if it matches the stored charger identification code, and rejects the charging request of the mobile bank server (300) if it does not match the stored charger identification code, and when the mobile bank server (300) rejects the charging request, it deletes the corresponding party information from the charging initiation list and sends a rejection message to the smartphone (20).

The above outlet (100) includes a current sensor (141) that detects a current waveform of commercial electricity supplied through a plug, and the remote management server (400) stores a charging current pattern that appears when charging an electric vehicle (1) with an emergency charger (10), and when the stored pattern is not found in the current waveform of commercial electricity supplied through a plug, remotely controls the supply of commercial electricity to be stopped, receives the amount of power supplied up to the point of charging stop, calculates a power rate, transmits the power rate together with the party information to the mobile bank server (300), and notifies the charging stop, and the mobile bank server (300) records the power rate up to the point of charging stop in a charging completion list, processes payment, and transmits a message to a smartphone (20) notifying the charging stop.

The present invention, configured as described above, simplifies the electric vehicle charger outlet while enabling application of electric vehicle charging power rates, allows use of an emergency charger carried around for emergency purposes as if it were public, and guarantees user authentication and reliable payment by linking with a mobile payment service (or mobile pay service) whose distribution is expanding due to the convenience of the payment method, thereby enabling the construction of an electric vehicle charging infrastructure that can be used by anyone, anytime, anywhere, is easy to construct, and can be installed without burden by any recipient because there is no concern about challenges.

According to an embodiment of the present invention, a user can be authenticated with a mobile payment service and the use of electricity for vehicle charging can be verified through an outlet, so that only the amount of electricity used when charging an electric vehicle can be applied to the electric vehicle charging electricity rate of the electric power company.

According to an embodiment of the present invention, the outlet can be used like a general outlet, but when used as a general outlet, the electric vehicle charging power rate of the power company is not applied, so that the power rate can be applied according to the purpose of power use.

Figure 2 is a block diagram of an electric vehicle charging system according to an embodiment of the present invention.
FIG. 3 is a flowchart of an electric vehicle charging method comprising an electric vehicle charging system according to an embodiment of the present invention.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the attached drawings so that a person having ordinary knowledge in the art can easily implement the invention. In describing the embodiment of the present invention, if it is judged that a detailed description of a related known function or known configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted.

Figure 1 is a configuration diagram of an electric vehicle charging system according to an embodiment of the present invention.

Referring to the above drawing 1, the electric vehicle charging system includes an outlet (100) connected to a commercial power source, an outlet tag (200) installed in the outlet (100) or around the outlet (100), a charger tag (210) installed in an emergency charger (10), a mobile bank server (300) that processes payment when a smartphone (20) that has a mobile payment app installed and requests payment by tagging the tag accesses and requests payment, and a remote management server (400) that is linked to the mobile bank server (300) and remotely controls the outlet (100), processes the amount of electricity supplied from the outlet (100) for charging an electric vehicle (1) and the corresponding payment fee, and transmits the information to a power company server (500) so that the user's electricity fee can be modified.

According to the electric vehicle charging system configured in this manner, when a smartphone (20) holder who has installed a mobile payment app (or mobile pay app) parks an electric vehicle (1) in a location where the outlet (100) is installed, executes the mobile payment app, tags the outlet tag (200) with the smartphone (20), and connects the outlet (100) and the electric vehicle (1) charging port (2) with an emergency charger (10), the electric vehicle (1) can be slowly charged using the outlet (100) as a charging infrastructure.

Here, the mobile payment app, outlet tag (200), and mobile bank server (300) are a tag-based payment system that processes payment based on information obtained by tagging the outlet tag (200) with a smartphone (20).

The tag-based payment system is a technology known through, for example, Patent Publication No. 10-2014-0095260, Patent Publication No. 10-2018-0070407, and Patent Registration No. 10-1780707, and is also a technology that is actually being provided as a service, for example, as 'Kakao Pay' transplanted to SNS services.

The above-described outlet tag (200) of the present invention may be a tag placed at a store in a known technology, and for example, may be configured as a QR code used in 'Kakao Pay', and as another example, may be configured as an NFC tag or an RFID tag, so that tagging can be performed in the mobile payment app according to the tag type.

However, according to the present invention, the difference from the known technology and actual service is that, in order to pay the electric vehicle (1) charging power fee, the remote management server (400) is linked to manage the charging start list and charging completion list, tagging is performed when charging starts to request payment, and payment is processed after charging is completed.

To this end, the mobile payment app can be configured to add an electric vehicle charging menu to an existing mobile payment app, and then tag the outlet tag (200) after selecting the menu. In addition, charging conditions, including the charging power amount or charging reservation time, can be entered in the electric vehicle charging menu.

The above outlet (100) is a component that replaces or newly installs a general outlet installed in a parking lot of an apartment, townhouse, multi-family house, single-family house, building, commercial building, public institution, or public parking lot, roadside parking lot, rest area parking lot, etc., and is connected to a commercial power source or an energy storage device (ESS) such as solar power generation or wind power generation through a power company's power meter, so that commercial electricity from a commercial power source can be supplied through a plug that is plugged in, just like a general outlet.

However, according to the present invention, the outlet (100) can identify and authenticate the emergency charger (10) and is remotely controlled by the remote management server (400).

Accordingly, the present invention is configured to be linked with an existing mobile payment system using a tag and a smartphone mobile payment app, thereby simplifying the system configuration without adding a separate payment system, ensuring payment processing, simplifying the configuration of the outlet (100), and allowing charging at the electric vehicle charging power rate of the power company using an emergency charger (20) that anyone who owns an electric vehicle (1) can purchase and have at a low price, so that it is not necessary to purchase a separate expensive mobile charger, and the cost of building the system can also be reduced.

Below, a detailed explanation is provided with reference to FIGS. 2 and 3.

FIG. 2 is a block diagram of an electric vehicle charging system according to an embodiment of the present invention.

The above outlet tag (200) is a tag on which a unique outlet identification code assigned to the above outlet (100) is recorded.

In the drawing, the outlet tag (200) is attached to the outlet (100), but it may be installed in a location close to the outlet (100) so that the outlet (100) can be located and identified.

The above charger tag (210) is installed on an emergency charger (10).

An emergency charger (10) is a portable charger in the form of a cable, including a connector (11) that is plugged into a charging port (2) of an electric vehicle (1), a plug (12) that is plugged into an outlet, a cable (13) that connects between the connector (11) and the plug (12), and an ICCB (In-Cable Control Box) that is mounted in the middle of the cable (13) to perform a charging operation, and can charge an electric vehicle (1) by connecting between an outlet connected to a commercial power source and an electric vehicle charging port (2). Of course, such an emergency charger (10) may only have a charging function that charges an electric vehicle with commercial electricity.

According to an embodiment of the present invention, the charger tag (210) is installed in the plug (12) of the emergency charger (10).

The above outlet (100) is installed in the parking spaces of the various users mentioned above, and the total power consumption of the user is measured by the power company power meter installed in the user, and the supplied commercial electricity is configured to be applied to the plug contact terminal (121) through a switch (130), a power meter (140), and a current sensor (141).

The above switch (130) is a switch for interrupting the supply of commercial electricity through the plug contact terminal (121) when the plug (12) is inserted into the plug contact terminal (121).

The above power meter (140) measures the amount of commercial electricity supplied to the plug (12) through the plug contact terminal (121).

The above current sensor (141) detects the current waveform of commercial electricity supplied to the plug (12) through the plug contact terminal (121).

A temperature sensor (122) for detecting the temperature of the plug contact terminal (121) or the temperature of the plug (12) inserted into the plug contact terminal (121), and a plug detection unit (123) for detecting whether the plug (12) is removed are installed in the plug contact terminal (121). The plug detection unit (123) may be configured by installing an elastic member that elastically deforms when the electrode terminal of the plug (12) is inserted into the plug contact terminal (121), and performing a switching operation by deformation of the elastic member. For example, the technology disclosed in Patent Registration No. 10-1764819 may be applied, and various deformation structures may be configured, so that a detailed description thereof will be omitted.

In addition, the outlet (100) is equipped with a tag reader (160) that can read a charger identification code recorded in a charger tag (210) by tagging a charger tag (210) provided on a plug (12) of an emergency charger (10), a communication module (150) for connecting to a remote management server (400) through a communication network, a user UI (170) for entering a password, and a controller (110) for controlling the overall operation of the outlet (100).

The above charger tag (210) and tag reader (160) can be implemented by utilizing an appropriate technology among various tag technologies such as RFID tag technology, NFC tag technology, and QR tag technology, and it is desirable to implement them in a way that has a small volume if possible.

The above communication module (150) is satisfied if it can be connected to the above remote management server (400). Although not shown in the drawing, it is also possible to construct a communication network in which multiple outlets (100) are installed in one user and a relay device communicating with the multiple outlets (100) is connected to the remote management server (400) via the Internet. The communication module (150) can be configured to fit the constructed communication network.

The above controller (110) normally keeps the switch (130) OFF, and when the charger tag (210) is tagged with the tag reader (160) to obtain a charger identification code, it transmits the charger identification code to the remote management server (400), turns the switch (130) ON according to the command of the remote management server (400) to start charging, accumulates the amount of power detected by the power meter (140) after the start of charging, and transmits the waveform of the current detected by the current sensor (141) according to the start of charging to the remote management server (400). Here, it is preferable to perform the tagging of the charger tag (210) when the insertion of the plug (12) is detected by the plug detection unit (123).

In addition, when the controller (110) detects the removal of the plug (12) by the plug detection unit (123) while charging has started, i.e. while charging is in progress, it turns off the switch (130) to stop supplying power and terminates charging, and notifies the remote management server (400) that charging has been stopped due to removal of the plug (12).

In addition, the controller (110) controls the switch (130) to turn on/off according to the temperature detected by the temperature sensor (122) to prevent overheating due to overload. For example, the controller (110) can be controlled to operate according to a program that controls the switch (130) to turn on/off so as to maintain the temperature below the limit temperature by setting the limit temperature in advance.

Then, the controller (110) turns off the switch (130) according to the command of the remote management server (400) to complete charging, transfer the accumulated power amount to the remote management server (400), and initialize the accumulated power amount to '0'.

That is, the controller (110) is remotely controlled by a remote management server (400) and supplies power for charging the electric vehicle (1).

However, it is desirable that the outlet (100) according to the present invention be used for other purposes in addition to charging an electric vehicle (1) within the home. To this end, a building manager tag is issued to the manager (or owner) of the home where the outlet (100) is installed, and the code recorded in the building manager tag is stored in the outlet (100). Then, when the building manager tag is tagged by the tag reader (160), the controller (110) turns on the switch (130) to supply power, so that it can be used like a general outlet, and notifies the remote management server (400) that it is being used as a general outlet. Of course, at this time, there is no need to calculate the power rate for charging the electric vehicle, so that the power amount detected by the power meter (140) does not need to be accumulated.

Since the method of using a building manager tag may be inconvenient, the controller (110) turns on the switch (130) so that it can be used like a general outlet when a pre-arranged password is entered through the user UI (170). Of course, even at this time, it notifies the remote management server (400) that it is being used as a general outlet. Of course, the password is entered to select whether to use it as a general outlet or for charging an electric vehicle.

Meanwhile, the above outlet (100) may be configured to use a lamp to indicate that it can be used as a general outlet.

The above mobile bank server (300) is a server that allows a smartphone (20) to access a mobile payment app (or mobile pay app) and make mobile payments, and includes a banking member management unit (310), a charging start management unit (320), a charging completion management unit (330), and a payment unit (340).

The banking member management department (310) manages member information registered with the mobile payment app, allows members to select payment methods such as card payment, account transfer, and point deduction, and manages the selected payment method.

The charging start management unit (320) is a component that tags an outlet tag (200) with a mobile payment app on a smartphone (20), transmits an outlet identification code, accepts a payment request, and operates, and transmits the member who requested payment and the received outlet identification code as party information to the remote management server (400), requests charging, and records and manages the party information in the charging start list. Here, the reason it is referred to as party information is because the outlet (100) that the member pays for and is identified by the outlet identification code corresponds to a merchant in conventional mobile payment. That is, the charging start management unit (320) records and manages the party information at the time of charging an electric vehicle (1).

In addition, the charging start management unit (320) receives charging conditions including charging power amount or charging reservation time from the mobile payment app of the smartphone (20), transmits them together with the outlet identification code, and requests payment. When this is accepted, the charging request is made by transmitting the party information and charging conditions to the remote management server (400).

Meanwhile, when a notification of a charging request rejection is received from the remote management server (400) and the party information is transmitted, the relevant party information is deleted from the charging initiation list. Then, a message is transmitted to the member smartphone (20) of the party information notifying that the charging request has been rejected.

The above charging completion management unit (330) is a component that receives a notification of charging completion or charging stop from the remote management server (400) and, when receiving the party information and power rate, accepts and operates, and records and manages the party information and power rate in the charging completion list. At this time, the party information is transmitted to the charging start management unit (320) and deleted from the charging start list, so that only the party information that is being charged remains in the charging start list.

The payment unit (340) processes payment so that the member of the party information pays the payment amount to the power company in a payment method set in advance based on the party information and power rate newly recorded in the charging completion list. As exemplified above, the payment method includes a card payment method, an account transfer method, and an accumulated point deduction method, and since these methods are known in the field of technology related to mobile banking servers and are actually in service, a detailed description is omitted.

The payment unit (340) transmits the payment amount to the smartphone (20) along with a charging completion or charging stop message during the payment processing process.

That is, the mobile bank server (300) manages the start and completion of charging, acts as an intermediary between the smartphone (20) and the remote management server (400), and performs the function of processing payment when charging is completed.

The above remote management server (400) is a server that remotely controls the outlets (100) installed in each user or individual outlets (100) when multiple outlets are installed in one user, and includes an outlet verification unit (410), a charger verification unit (420), an outlet remote control unit (430), a charging fee calculation unit (440), a charging history management unit (450), and a data storage unit (460).

In the above data storage unit (460), the outlet identification code of the outlet tag (200) installed for each outlet (100), the outlet (100) installation location (or installation recipient) and the power meter identification code of the recipient where the outlet (100) is installed are stored so as to be mutually matched, and in addition, the charger identification code of the charger tag (210) installed in the plug (210) of the emergency charger (10), and the charging current pattern of commercial electricity supplied to the emergency charger (10) when charging an electric vehicle (1) with the emergency charger (10) are also stored.

Here, with regard to the charging current pattern, the current supplied to the battery of the electric vehicle (1) for charging from the emergency charger (10) has a different pattern from the current supplied to other types of electric devices, and the current waveform of the commercial electricity supplied to the emergency charger (10) can also be distinguished from the current waveform supplied to other types of electric devices by this different current pattern. Accordingly, in the present invention, when charging with the emergency charger (10), the pattern of the current waveform of the commercial electricity supplied to the emergency charger (10) is obtained in advance and stored as the charging current pattern. As a more reliable method, the emergency charger (10) can be configured to periodically generate a mutually agreed-upon specific current pattern during charging, and the electric vehicle can be charged only when the emergency charger (10) is connected to an outlet (100), as described below.

The above outlet verification unit (410) verifies the outlet identification code of the party information and the charging conditions among the party information received when receiving a charging request from the mobile bank server (300). That is, if the received outlet identification code exists in the outlet identification codes stored in the data storage unit (460), it is considered to be verified. Then, the location of the outlet (100) corresponding to the outlet identification code is identified based on the mutually matched outlet identification code and outlet installation location stored in the data storage unit (460).

Meanwhile, the outlet verification unit (410) records and manages an outlet (100) that has been notified to be in use as a general outlet among the outlets (100), and if the outlet identification code of the party information transmitted from the mobile bank server (300) belongs to the outlet identification code of an outlet (100) being used as a general outlet, it notifies the mobile bank server (300) of the rejection of the charging request.

The above charger verification unit (420) waits for a charger identification number to be transmitted from the outlet (100) at the identified location, and when the charger identification number is transmitted from the outlet (100), it checks whether it exists in the charger identification code stored in the data storage unit (460), and if it exists, it is considered verified.

Of course, the charging request of the mobile bank server (300) is approved only when it is verified by both the outlet verification unit (410) and the charger verification unit (420), otherwise, the charging request is rejected and notified to the mobile bank server (300).

When verified in this manner, the outlet remote control unit (430) remotely controls the outlet (100) at the identified location to supply commercial electricity according to the charging conditions, and when charging is completed or stopped, receives the amount of power supplied to calculate the power rate, and transmits the calculated power rate, corresponding party information, and other notification messages to the mobile bank server (300), thereby enabling the electric vehicle (1) to be charged according to the charging conditions with commercial electricity supplied from the corresponding outlet (100).

And, the above outlet remote control unit (430) obtains the power company power meter identification code of the user where the outlet (100) used for charging the electric vehicle is installed according to the data stored in the data storage unit (460), and transmits it to the power company server (700) along with the amount of power supplied according to the completion or cessation of charging, and requests a deduction from the user's power consumption.

The above power company server (700) may be, for example, a server built for remote metering.

The above charging fee calculation unit (440) calculates the fee for the amount of electricity used to charge an electric vehicle by applying the electric vehicle charging power fee from the electric power company's electricity fee.

The above charging history management unit (450) records and manages information related to a remotely controlled outlet (100) based on the party information (member information, outlet identification code) received when requesting charging from the mobile bank server (300), namely, party information, outlet installation location, power company power meter identification code, charging start time, charging completion or charging stop time, power supply amount, supply time zone, and calculated power rate.

The above charging fee calculation unit (440) and charging history management unit (450) support the operation of the outlet remote control unit (430).

The remote control method by the above outlet remote control unit (430) is as follows.

Among the light load time zones and charging reservation time zones of the electric vehicle power rate set by the power company, the charging reservation time zone is given priority, the switch (130) of the outlet (100) is turned on according to the applied time zone, the power amount measured by the power meter (140) is transmitted in real time, remotely monitored, the charging completion time is predicted, and when the charging completion time is reached, the switch (130) is turned off. Of course, the emergency charger (10) is assumed to be capable of charging at any time when commercial electricity is supplied.

If the charging condition includes the charging power quantity, the charging completion time is predicted to charge according to the charging power quantity, and if not included, the charging completion time is predicted to be the time of full charging. This prediction can be found out, for example, by real-time fluctuations in the charging power quantity. However, the outlet (100) may be configured to control the charging power quantity to be transferred to the outlet (100) and the controller (110) of the outlet (100) to charge according to the charging power quantity. When charging, the charging time can be known from the fluctuation pattern of the power quantity in the outlet (100), and of course, the charging time period should also be transmitted to the outlet (100) to determine the charging time.

In addition, after the switch (130) is turned on, the current waveform of commercial electricity detected by the current sensor (141) is transmitted in real time, and if the charging current pattern stored in the data storage unit (460) is not found, the switch (130) is turned off to stop the supply of commercial electricity, and the amount of power supplied up to the point of charging stop is received from the outlet (100) to calculate the power rate. Then, the calculated power rate is transmitted to the mobile bank server (300) together with the party information and the charging stop is notified.

In addition, if the plug detection unit (123) notifies that a plug has been inserted after the charging request has been approved, it monitors whether a plug removal is notified. If a plug removal is notified, the power supply amount up to that point is received from the outlet (100) to calculate the power rate, and the calculated power rate is transmitted to the mobile bank server (300) together with the party information, and the charging stop due to the plug removal is notified.

In this way, by rejecting a charging request, notifying completion of charging, or notifying suspension of charging from the remote management server (400), the mobile bank server can manage the list and process payment according to the notification as described above.

Meanwhile, costs are incurred in providing electric vehicle charging services by installing and operating an outlet (100), and there is a basic rate among the electric vehicle charging power rates set by the electric power company. In addition, one electric vehicle (1) can be charged using multiple outlets (100), so it is advisable to collect payment fees on a monthly basis and allow additional costs to be paid, taking these points into consideration.

To this end, the charging fee calculation unit (440) of the remote management server (400) sets and stores the service usage fee calculation standard in advance, and transmits the service usage fee and basic fee to the mobile bank server (300) on a date designated every month.

For example, the service usage fee and basic fee can be calculated based on the history managed by the charging history management unit (450) and the ratio of the charging power amount per smartphone (20) owner to the total charging power amount. Of course, it is calculated for each outlet (100).

And, the mobile bank server (300) withdraws the payment amount from the member-linked account or deducts it from the points for the member who uses the payment method of account transfer or accumulated point deduction, accumulates it for each member on a monthly basis, and then additionally accumulates the basic fee on a designated date every month and processes the payment in bulk to the power company. The service usage fee is processed for payment to be received by the operator of the remote management server (400). Of course, in the case of card payment, the basic fee and service usage fee can be added and processed for payment without using the aforementioned accumulation method.

FIG. 3 is a flowchart of an electric vehicle charging method comprising an electric vehicle charging system according to an embodiment of the present invention.

The main operations performed in each component of an electric vehicle charging system when charging an electric vehicle are described with reference to Fig. 3 above.

When an electric vehicle (1) driver parks the electric vehicle (1) close to an outlet (100), runs a mobile payment app on a smartphone (20) (S10), tags an outlet tag (200) equipped on an outlet (100) (S11), and enters charging conditions according to a menu (S12), the mobile payment app obtains an outlet identification code that can identify the outlet (100) and the charging conditions requested by the driver.

The mobile payment app of the smartphone (20) transmits the outlet identification code and charging conditions to the mobile bank server (300) and requests payment (S13). The payment request at this time is not a request to process payment immediately, but a request to process payment after charging is completed or stopped.

When the mobile bank server (300) receives a payment request, it transmits the member information and the outlet identification code received at the time of payment request to the remote management server (400) along with the charging conditions as the party information using the mobile payment app of the smartphone (20) that requested the payment, and makes a charging request (S20). In addition, the mobile bank server (300) adds the party information to the charging initiation list (S21).

The remote management server (400) that received the charging request verifies the outlet identification code of the party information (S22). That is, if the outlet identification code of the party information is not stored in the data storage, the mobile bank server (300) is notified that the charging request is rejected, so that the party information is deleted from the charging start list and the smartphone (20) is notified.

If the outlet identification code of the party information is stored in the data storage, it waits until the outlet identification code is sent from the outlet (100) identified by the outlet identification code.

The driver will connect the emergency charger (10) between the outlet (100) and the electric vehicle (1) charging port (2) for charging. After that, the driver may stop running the mobile payment app (S12'). Of course, the mobile payment app can receive SNS messages from the mobile bank server (300) even when it is stopped.

The outlet (100) tags the charger tag (210) installed in the plug (12) of the emergency charger (10) with a tag reader (160) to obtain an outlet identification code (S30) and transmits it to the remote management server (400) (S31).

The remote management server (400) first verifies the emergency charger (10) using the charger identification code transmitted and received from the outlet (100) previously identified by the outlet identification code (S32). That is, if the received charger identification code is not stored in the data storage, the remote management server (400) notifies the mobile bank server (300) that the charging request is rejected, so that the information of the party is deleted from the charging start list and the smartphone (20) is notified.

If the received charger identification code is a code stored in the data storage, the remote management server (400) approves charging and remotely controls the outlet (100) to supply power according to the charging conditions (S40). Accordingly, the emergency charger (10) charges the electric vehicle (1) using commercial electricity supplied through the outlet (100).

In addition, the remote management server (400) receives the current waveform of commercial electricity supplied to the emergency charger (10) through the outlet (100) from the outlet (100) (S50) and performs a second verification of the emergency charger (10) (S51). That is, if the current waveform does not show a charging current pattern stored in the data storage unit related to the emergency charger (10), the outlet (100) is remotely controlled to stop the power supply, stop charging, and if the charging current pattern is shown, continue charging until charging is completed. As described above, the charging interruption may also occur when the plug (12) of the emergency charger (10) is pulled out of the outlet (100).

When charging is completed or stopped, the remote management server (400) obtains the amount of electricity used for charging from the outlet (100), calculates the electricity rate according to the amount of electricity (S61), notifies the mobile bank server (300) (S62), and requests the electric power company to deduct the amount of electricity supplied for charging from the measured amount of electricity of the electric power company's electric power meter that measures the amount of electricity supplied to the outlet (100) used for charging the electric vehicle (S63).

The mobile bank server (300) adds the power rate calculated based on charging completion or charging stop to the charging completion list along with the party information, and deletes the added party information from the charging start list (S70).

Then, the mobile bank server (300) transmits a message related to charging completion or charging stop and the power charge to the smartphone (20) and processes the payment for the power charge (S71). As described above, the payment charge can be accumulated on a monthly basis and then processed for payment.
