It is to be understood, however, that the invention is not to be limited to the specific embodiments, but includes all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

The terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, an electric vehicle charging system of the present invention includes an electric supply unit 100 for supplying electric power; A charging device 20 for charging the electric vehicle 300 with electricity supplied from the electric power supply unit 100; An electric vehicle (300) charged by the charging device (200); A billing server 400 for calculating an electricity bill based on the charged electricity quantity of the electric vehicle 300; Stores and manages the information of the electricity supplying unit 100 and the charging device 200 and transmits the charging electric quantity of the electric vehicle 300 from the charging device 200 to the charging server 400, An operating company server 500 that receives the billing request from the charging server 400 and charges the charging device user; And a settlement server 600 for receiving a calculation charge for the charged electricity quantity from a charging device user.

The cost settlement for the charged electricity amount is not limited to the specific method such as card, apartment management fee and giro.

The charging device information may be an owner name, a telephone number, and an address.

The electricity supply unit information may be a name of a building or the like where the electricity supply unit is installed, a building name, a building address, outlet information, meter information connected to the outlet, and the maximum charging electricity amount information of the outlet.

The information may be recorded in, for example, an RF card or the like, and these information may be stored and managed in an operating company server.

The operating company server 500 judges the information by associating the information with a unique ID given to the electric supply unit and the charging device, respectively. The operating company server 500 and the charging server 400, the operating company server 500 and the charging device 200, the operating company server 500 and the payment server 600 are connected to each other by, for example, wifi, And power line communication, and may be interconnected via various communication means, optionally with wired or other charging.

The electric power supply unit 100 is an outlet having at least one connection port connected to the charging device 200 so as to supply external electric power supplied from, for example, a power company or a building management station to the electric vehicle 300, It can be constructed at any place, not only at a specific place such as a house and a building, but can be connected to a separate meter from a meter installed at a power company or building station. Such a case may be, for example, a case where the electric power supply unit is installed in a building or the like.

The electricity supplier 100 is provided with a unique ID, for example, in the form of a bar code or an RF so that the maximum charging electricity quantity information of the outlet can be read together with the outlet information and the meter information connected to the outlet. In this case, since the RFID transmits a signal with a minute current, it is often not recognized due to electromagnetic waves when it is located near a high-voltage, high-current outlet such as an outlet of a power supply (for example, It is installed in the form of a label with a minimum distance from the outlet so that the RFID signal value can not be recognized due to the electromagnetic wave.

Therefore, when the electric supply unit 100 and the electric vehicle 300 are electrically connected through the charging device 200, the unique ID of the electric supply unit 100 is sensed by the charging device 200, The information of the electricity supplier 100 and the meter information connected thereto are determined by the operating company server 500 having received the unique ID to determine the maximum charged electricity quantity information. This information determination is possible because the operating company server 500 stores and manages information of all the electricity supplying units managed.

As shown in FIG. 2, the charging apparatus 200 includes a first connection unit 210 electrically connected to the electricity supply unit 100, and an operation control unit 230 controlling the operation according to the charge control condition and the communication with the operating company server 500 A controller 220, an operating unit 230 operated to perform operations from the start to the completion of charging, and a second connecting unit (coupler) 240 electrically connected to the electric vehicle 300, And the second connection units 210 and 240, the controller 220, and the operation unit 230 are interconnected through an electric wire and a data transmission line.

The charging device of the present invention may further include a sensing unit 250 for sensing the electric power supply unit 100 and a measuring unit 260 for measuring the amount of charged electricity and the electric power supplied from the electric power supply unit, . The sensing unit 250 senses the RFID of the electricity supplying unit 100 and is preferably configured to be close to the second connecting unit 240. [

The first connection unit 210 includes a first temperature sensor 211 for sensing the temperature of the electricity supply unit 100. The second connection unit 240 is connected to a second temperature A sensor 241 is built therein.

The first temperature sensor 211 incorporated in the first connection part 210 detects an overload of the electric supply part 100, that is, a temperature of the socket outlet. When the socket is overloaded, the temperature is abnormally overheated and the load switch ) Is cut off and the electric wire is lost. Accordingly, when the overload is detected, the sensed value is processed in the controller 220, and the charging is controlled according to the processed result.

The second temperature sensor 241 incorporated in the second connection unit 240 senses that the temperature is abnormally overheated when the electric vehicle charging port is overloaded, the sensed value is processed in the controller 220, The charging is controlled according to the following equation.

The temperature-dependent charge control program is optionally stored in the controller 220 or the operator server 500 of the charging device 200 and is optionally driven by the controller 220 or the operator server 500.

Further, the controller 220 receives and processes the sensed values of the first and second temperature sensors 211 and 241, and controls the charging if the processed result satisfies the condition for controlling the charging. Here, the charge control condition may include a condition for completely stopping the charging, a condition for temporarily stopping, a condition for adjusting the amount of charge current, and the like.

The condition for completely stopping the charging is a case where a high risk is expected because the temperature rises excessively. The condition for temporarily stopping the charging is a case where the charging is stopped and restarted for a certain period of time. As shown in FIG. These determinations are made based on a result of comparison between the temperature range and the actual sensed temperature in a state where the normal temperature range of the electricity supplying unit 100 is stored and managed.

The charge current amount adjustment is performed by associating this information with the temperature of the electric supply unit 100 and the electric vehicle charging port since the RFID configured in the electric supply unit 100 includes the maximum charged electricity amount information.

The above conditions and the resulting charge control may be variously configured in addition to the above-described types.

On the other hand, charging control may be performed in the operating company server 500 as described above. In this case, the temperature of the electric supply unit 100 and the electric vehicle charging port, sensed by the first temperature sensor 211 of the first connection unit 210 and the second temperature sensor 241 of the second connection unit 240, 220), the process value (sensing temperature) is transmitted to the operating company server 500 through the wired / wireless communication network, processed, and transmitted to the controller 220. In response to the control signal, So that it is controlled.

The charging control result is transmitted to the operating company server 500 again, and the operating company server 500 shares the charging fee with the charging server 400 so that the charging fee is calculated, And search.

The operation unit 230 is constituted between a controller 220 and a second connection unit 240 connected to the electric vehicle 300. The operation unit 230 is connected between the electric supply unit 100 and the electric vehicle 300, When electrical connection is made, manual operation becomes possible.

The operation unit 230 is operated so that the notification of, for example, "connected for charging", "charging", "charging completed", etc. is processed in the controller 220 and then released to the outside.

Also, the charging device 200 recognizes the electric connection between the electric supply unit 100 and the electric vehicle 300, the charging process of the electric car 300 connected to the electric device 300, And transmits the electric supply unit information, the charged electric quantity information, the charging device information, and the electric vehicle information to the operating company server 500 in order to calculate a reasonable cost based on the data required for calculating the charged electricity amount and other charges.

Meanwhile, the setting of the charging device 200 of the present invention may use a remote communication module such as CDMA, GSM, 3G, 4G or LTE, or a Bluetooth module capable of wifi, Zigbee, RF, infrared communication,

The setting of the charging device 200 may be a method of fetching data from the operating company server 500 and a method of fetching data from other terminals such as a smart phone.

The charging device 200 stores and manages charging information such as electricity supplier information, charging device information, charging electricity quantity measurement, etc., and transmits the information to the operating company server 500.

The billing server 400 calculates the charge for the amount of electricity used through the electricity supplier, that is, the electricity supplier based on the electricity supplier information, the charge electricity quantity information, the charge device information, and the electric car information transmitted from the operating company server 500 And a calculation charge for charging electricity used through the electricity demanding entity, that is, the charging device, separately from the owner of the electricity supplier and the server of the operating company, for example, a server of a power company or a building management station.

That is, the billing server 400 charges the owner of the electricity supplier for the calculation of the general electricity quantity among the total electricity quantity used through the electricity supplier, and charges the operating company for the estimation charge for the electric car charge quantity.

The operating company server 500, when receiving from the charging server 400 a calculation charge for the charged electricity quantity of the electric vehicle 300 as described above, charges the user of the charging device. Or charge the charging device user after prepayment.

The operator shall pay the charges charged by the electric power company or the building station from the charging device user, and the cost of transferring the electric power to the electric power company or the building station shall be as determined separately.

Meanwhile, in the above description, when the charging device 200 detects the electric supply part information, the operation server 500 transmits and processes the electric supply part information to the charging server 400. However, no.

For example, the electricity supplier information sensed by the charging device 200 is simultaneously transmitted to the operating company server 500 and the charging server 400, and the charging fee may be transferred from the charging server 400 to the operating company server 500, May be configured to have a flow of receiving and charging it to the charging device user.

The charging device 200 of the present invention can use both general power and residential power.

In other words, when using general power, it is directly offsetting with the customer. It is possible to perform direct offset processing because there is no progressive application according to the usage amount for general power consumers. When using residential power, It is impossible to directly offset the building with the electric car charging outlet.

The charging device 200 according to the present invention can be charged only if the outlet is registered in the server 500 of the operator anywhere in the nation. Since the existing outlet infrastructure is used as it is, the cost is remarkably reduced. It is possible to respond appropriately to various charging needs such as starting and stopping charging and adjusting the amount of charge according to time zone, region, and power reserve ratio. For example, when a power company or a building station requests a power shortage, a vehicle charged 10 kilowatts or more in a current charging electric vehicle nationwide or in a building may be recharged after a predetermined time (for example, two hours) It is possible to reduce the current charge by half in all charging electric vehicles. In other words, it adjusts the charge according to the power supply situation in real time through remote monitoring and adjustment, thereby controlling the power supply and supply, thereby enabling stable power supply.

Meanwhile, the charging apparatus of the present invention is provided with a function of supplying power to the power network from an electric vehicle battery, that is, a V2G function through reverse transmission. These functions include a meter for real-time meter reading of the amount of power transferred back from the electric car battery to the power grid, a meter associated with the remote meter reading and control function at the operator server and measuring the amount of reverse- Can be performed by transferring the meter number of the power meter to the operating company server.

By connecting the 220V power supply to the charging device connection part multi-tap using the electric car as a large battery by simply connecting the multi-tap (Fig. 13) to the connection part of the charging device by the application function, to Machine function can be achieved so that the electric vehicle can be expanded as a means of outdoor power supply in addition to simply moving means.

 3 shows the configuration of the operating company server 500. In the state where the electric supply unit DB and the charging device DB are registered and managed for the first time, they are updated according to the variation of the subscribers (electric supply unit, charging device) And is also stored and managed in the billing server 400.

The operating company server 500 includes a charging electricity quantity automatic setting function capable of remotely adjusting the charged electricity quantity so as to cope with the power supply situation according to the nationwide area, time, and the like.

This function can prevent unexpected national blackout situations as well as charge stoppage that may occur due to the weakening of electric power, for example, because electric supply capacity of each electric power supply unit installed in every region may be different. When the maximum amount of electricity that can be safely supplied to the electric vehicle 300 from the electric power supply unit 100 is measured by the measuring unit 260 of the charging apparatus 200, And controls the charging device 200 so that the charging is performed only within this electric quantity range.

More specifically, when charging the battery with a slight increase in the amount of electricity, the voltage current fluctuates at a constant current, or the charging electric power quality deteriorates due to shaking. Such a point is found and charged to the corresponding electric quantity And the like.

In addition, when two or more charging devices are connected to one electric supply unit at the same time or at a time difference to perform charging, the operating company server 500 may lower the charging quality of one or more electric vehicles connected thereto, The server 500 includes a function of remotely setting the charging electricity quantity for each connection port constituting the electricity supplying section 100 so that the sum of the charging electricity quantities does not exceed the maximum charging electric energy that can be supplied from the electric supply section.

The charge quality degradation may be caused not only when one or more charging devices are connected to one electric supply section but also when one charging device is connected to each of the two electric supply sections, It can also occur when connected.

For example, most of the outlets installed in the parking lot are connected to the same electric wire. Therefore, when electric cars or other electric appliances are electrically connected to one or more outlets, the electric power is weakened and the quality is deteriorated.

In addition, the operating company server 500 stores and manages all of the conditions under which charging has been performed, such as the voltage and current fluctuation point, the number of charging devices connected to one electric supply unit, and the number of charging devices connected to one or more electric supply units, When the other charging device 200 is connected, the charging is performed within the limit charging quantity based on the information, thereby preventing the deterioration of the charging quality.

As described above, all the information determined by the operating company server 500 is transmitted to the charging device 200 so that charging is performed according to the newly set conditions.

This can be explained as follows. When electric power is supplied or received from a power company or a building management station, or the target electric vehicle, time, area, vehicle manufacturer, And electric power shortages in the whole country are prevented in advance, and when a new charging situation occurs in a plurality of outlets connected to the same electric wire, the charged electricity amount is divided so as to prevent problems such as short- do.

This function is possible by exchanging information between a utility or a building station and an operator.

For example, a power company or a building management station real-time grasps the power supply situation, so that the power supply situation of the region where the electricity supply unit is installed is shared with the operating company in real time, and the operating company transmits a control signal to the charging apparatus .

For example, assuming that 100 electric power supply units consisting of two connection ports are installed in the whole area of Seoul, 2014. 03. 25. If total electric power consumption of 1 million kw is estimated at 800,000 kW, Since it can be estimated that the electric power can be used for charging a car, it can be distributed in proportion to the maximum electric power preset to 100 electric power supply units installed in Seoul area.

In the above, it is also possible to judge the usage state of the general electric vehicle and the electric vehicle charge in real time without discriminating between the general electric use estimated amount and the electric vehicle charged electricity quantity, so that the charged electric energy can be adjusted within a range that does not hinder the use of general electricity.

Further, whether or not the electric power supply unit to be charged at the same time is connected to the same electric wire is determined based on the fact that the electric power supply unit is charged through the electric power supply unit. The charging electric power supply amount may be set, and if the electric power is not connected to the same electric power line, the charge electric power supply amount may be set in the subdivision of the building or area where the electric power supplying unit is installed.

Further, according to the present invention, the usage fee may be calculated differently depending on the charging time and the charged electricity amount

There is provided a charging operation condition setting function in which, for example, a charging device to which an electric vehicle is connected is connected to an electric power supply unit, a charging start time and a completion time are set and charging is performed according to the set charging start time and completion time.

That is, if the condition is set through any one of the user's smartphone, the home page of the operating company, and the charging device, the setting information may be determined by the charging device and charging may be performed according to the setting information have.

In more detail, the present invention stores and manages all of the information in the operating company server 500 in order to make a reasonable fee calculation based on such information in consideration of the difference in the electricity billing criteria according to the use time and the like For example, a calculation fee database that reflects both the usage time and the charge electricity amount on the operating company homepage so that charging is started with the time zone, usage amount, and basic charge confirmed, And the fee is accurately calculated according to the conditions for selecting both the use time and the charge electricity amount, the use time and the charge electricity amount.

Such a function can, for example, enable the charging to be started at a set time when the charging device is kept connected to the electricity supply unit and the charge is generated at a low cost. If the use of the car is not immediately required and the charge is to be saved .

The present invention also includes a charging operation setting function for charging only a part of the electricity amount of the total charged electricity amount for the electric vehicle and for charging the remaining electricity amount at the set time (time).

More specifically, assuming that the amount of electricity charged to a predetermined electric vehicle is 20 kilowatts, for example, 10 kilowatts is charged immediately after connecting the charging device to the electric power supply, and the remaining 10 kilowatt is charged at a set time And to start again and complete.

For example, when the car is not used immediately, the cost burden on the user can be alleviated.

When charging is done according to the normal situation or specially set conditions as above, the operator charges the owner of the electric car only the charge calculated for the electricity used for charging and collects the collected charges from the operator The cost is handled by depositing it in the electric power company or building station.

As described above, in the system of the present invention, an electric vehicle requiring charging can freely use all electric power supply units managed by an operating company, and the charges can be reasonably estimated. (For example, a power company or a building management station charge meter identification number) is registered and managed in the operating company server 500 in advance, and the electricity amount used for charging the electric vehicle It can be done by calculating electricity charges separately.

Various embodiments will be described with reference to the drawings.

As shown in FIG. 5, the charge can be offset with individual apartments. The RFID tag is installed in the parking lot outlet of the apartment complex by application of the individual apartment complex, (Time, amount of charge, charge, lake, used outlet, etc.), after receiving money from the charge server at the operating company server, and paying the public electricity charge for the usage amount, for example, , It is possible to have an existing flow of depositing a public electric charge to a utility company in an individual apartment complex.

As shown in FIG. 6, the charging system of the present invention does not have progressive charging due to use of general-purpose grade power, and does not interoperate with a power company. Based on the fact that charging infrastructure can be built in most apartments (more than 90%) nationwide, electric car charging customers check charge and deposit money for operating company server, join as user member, It is possible to build a system that can check charge, select a charging plan, and apply for additional services. The server of the operating company can confirm the charge charge and deposit the apartment complex, It is possible to build a charging infrastructure that can check statistics such as fees.

 FIG. 7 shows a system interlocking with a power company. The data interlocking server can be constructed. However, the security server can be located outside the power company with security first, From the operating company server to the interworking server, the usage amount, usage time, user (operating company member number, etc.) per user can be transmitted and the power company can transmit the total power consumption fee, the customer ID or the meter number to the operating company server.
