In terms of supplying electricity, unlike other commodities, electricity is characterized by supply and demand in real time. As a result, many large wholesale trades that buy and sell electricity rent or sell electricity from other power supply (or distribution) companies between the generators that produce electricity and the power companies that deliver and sell the electricity. This is common. This is attributable to the fact that once a hydro, thermal, wind, and nuclear power plant is built, the amount of electricity produced is constant while the demand for electricity varies by time zone or region.

Meanwhile, due to the reduction of petroleum resources and the spread of pollutants, various attempts have been made to replace internal combustion engines. Hybrid cars using electric oil and electricity alternately or electric cars driven only by electricity have been developed and marketed. These electric cars do not emit soot or pollutants by being driven by electricity, and unlike internal combustion engines, they have little infrastructure for electric charging and thus have a lot of difficulties in commercialization.

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

1 conceptually illustrates an example of applying an intelligent electric charging control box and an intelligent electric charging control box according to the present invention.

The intelligent electric charging control box 10 (hereinafter referred to as a terminal box) according to the present invention is applicable to a device requiring electric charging, and a vehicle (electric vehicle 5), and the charging card 2 is inserted therein. At the time of access (in the case of an RFID card), the protective cover 11d of the power supply 11 is opened to allow the user to use electricity.

Here, the electric vehicle referred to in the present invention can be electrically driven, a vehicle having two or more wheels, motorcycles, bicycles and two wheels to be powered by the electric furnace power. It may be any one of the moving means using a wheel such as three wheels or four wheels.

In addition, in the present invention, the charge card,

-When sold in a parking lot, a convenience store, and other stores, and has a form of a prepaid card, it may be either a postpaid card or a credit card.

-RFID tag may be attached. If the RFID tag is attached, the device for reading the charging card should also include an RFID reader.

-Depending on the time of use, it may take the form of a postpaid card which will be processed later.

-If the recharge card is in the form of a prepaid card, the user can pay for the prepaid recharge card and use electricity with the purchased recharge card (prepaid card).

In the case of a credit card, the terminal box 10 is networked with a central server (not shown) to request payment, and the central server may perform payment through a credit card company server.

The electric power supply part 11 is equipped with the socket 11a which outputs a commercial alternating current, and the protective cover 11d which opens and closes the socket 11a. The protective cover 11d is applied throughout the present invention, and when a suitable charging card 2 is inserted into the terminal box 10 (close when the charging card is an RFID card), the electric vehicle 5 The charging cable 6 is open so that it can be inserted into the socket 11a and vice versa. This has the meaning of preventing inappropriate users from stealing electricity in the terminal box 10 of the present invention that can be installed anywhere.

When the user of the electric vehicle 5 inserts the charging card 2 into the terminal box 10, the terminal box 10 authenticates the charging card 2 and checks the balance of the charging card 2.

The terminal box 10 supplies electric power to the electric vehicle 5 according to a user's desired method when a balance remains in the charging card 2.

The user may process the charging start time, the charging completion time, and the reserved charging through the keypad 13. Keypad 13 is assigned a key for setting the charging start time, charging completion time, and reservation charge, the user can set the desired time using these keys. To this end, the keypad 13 further includes a numeric key, in addition to the charging start time, the charging completion time, and the key for setting the reservation charge.

After the charging cable 6 is connected to the socket 11a, the terminal box 10 may stop charging by checking whether the battery built in the electric vehicle 5 is charged. Normally, the battery of the electric vehicle 5 is provided with a function to cut off power supplied through the socket 11a when fully charged. This will be described with reference to FIG. 10.

10 conceptually illustrates an example of a charging method of an electric vehicle.

In the drawings, reference numerals 1, 3, and 4 denote switches, charging circuits, and batteries, respectively. The charging circuit 3 converts commercial alternating current provided from the terminal box 10 into direct current and charges the battery 4 with the converted direct current. The charging circuit 3 continuously monitors the charging state of the battery 4, and when the battery 4 is fully charged, drives the switch 1 to block input of commercial AC. Through this, the charging circuit 3 prevents overcharging of the battery 4 and minimizes the burden on the charging circuit 3 itself.

If the battery is continuously charged after being fully charged, the battery may be overcharged, which may shorten the life of the battery and may damage the battery. Therefore, the terminal box 10 of the present invention determines whether the battery is fully charged according to the method described in each of the following.

1) When the battery of the electric vehicle 5 is fully charged, when the charging circuit of the electric vehicle 5 cuts off the power provided from the socket 11a, the power supplied from the socket 11a to the charging cable 6 decreases. The controller detects this and determines whether the charging is completed.

2) When the battery of the electric vehicle 5 is fully charged, if the charging circuit of the electric vehicle 5 cuts off the power provided from the socket 11a, the current flowing from the socket 11a to the charging cable 6 decreases. By using this, it is determined that the battery is fully charged when the amount of current falls below the reference value (usually, the average value of the current flowing when charging the electric vehicle).

3) Electricity is supplied using the electric vehicle (5) and a dedicated cable. The dedicated cable is provided with a pair of terminals for supplying commercial AC and a charging terminal for receiving charging information of the battery. The charging circuit (not shown) built in the electric vehicle 5 provides charging information of the battery to the charging terminal, and the terminal box 10 may calculate and display the charging amount of the battery, the expected charging time, and the like, to the user.

Meanwhile, the terminal box 10 may have a separate network connection card for wired or wireless network connection.

In the drawings, reference numerals 15 and 16 denote an antenna and a wireless network access card, respectively. In this case, the terminal box reads the card information through the charging card 2 and provides the card information to the server (not shown). The card is authenticated and approved. At this time, the wireless network connection card 16 is preferably connected to the mobile communication server for providing a wireless communication service to the mobile phone, through which the terminal box 10 can be arranged in any place. Of course, even without the wireless network connection card 16, the terminal box according to the present invention can perform the charging itself, the manner in which the terminal box 10 is network-connected with the server (not shown) is not limited by the wireless connection method. This will be described later in detail.

Here, reference numerals and descriptions shown in FIG. 1 may be referred to and applied in all embodiments to be described later.

Figure 2 shows a block diagram of a terminal box according to an embodiment of the present invention.

The illustrated terminal box includes a charging control unit 12, a keypad 13, a card reader unit 14, and a power supply unit 11.

The power supply unit 11 includes a socket 11a and a power amount calculation unit 11b. The socket 11a is provided for the charging cable 6 of the electric vehicle 5, and when engaged with the charging cable 6, provides a commercial alternating current to the charging cable 6. The power amount calculator 11b measures the power transmitted to the charging cable 6 through the socket 11a. The external shape of the power supply 11 is the same as that of the power supply 11 shown in FIG. 1, and includes a protective cover 11d and a socket 11a.

The card reader unit 14 reads the information of the charging card when the charging card is inserted. The card reader unit 14 can read the type of the charging card, the balance of the charging card, and the user information. The type of the charging card and the read result are provided to the charging control unit 12.

The charging control unit 12 determines whether the card is allowed to use electricity through the card information provided from the card reader unit 14. As a result of the determination, in the case of a card which allows the use of electricity, the AC power supply unit 11 is controlled so that commercial AC may be output from the socket 11a. In addition, the charging control unit 12 opens the protective cover 11d so that the user can insert the charging cable 6 into the socket 11a.

The charging control unit 12 receives power amount information measured by the power supply unit 11. The charging control unit 12 calculates the amount of power required to charge the electric vehicle 5 and the corresponding cost according to the measured amount of power information. The cost calculation varies depending on the time zone where the user charged the electric vehicle 5 and the charging region. For example, if the user charges the electric vehicle 5 after 12 o'clock, the late-night electricity rate is applied depending on the region (or country), and the late-night electricity rate is usually 30% to 50% compared to the weekly electricity rate. do. In this case, the charging control unit 12 calculates a cost according to the late-night electric plan which is 30% to 50% discounted, and after the charging for the electric vehicle is completed, the balance of the charge card is deducted by the calculated cost (prepaid charging card of the Occation).

The charging control unit 12 determines that the charging of the electric vehicle 5 is completed when the amount of power output to the socket 11a is less than or equal to the preset reference amount w_ref as a result of the measurement of the electric power calculating unit 11b. This is because the charging circuit (not shown) of the electric vehicle 5 cuts off commercial alternating current applied through the charging cable 6 in order to prevent overcharging of the battery built in the electric vehicle 5.

The keypad 13 allows the user to perform the charging start time, the charging completion time, and the scheduled charging by themselves. The keypad 13 is composed of a numeric key and a command key, and the command keys correspond to a charge start time, a charge complete time, and a reserved charge, respectively. When the user sets the time through the keypad 13, the display device 18 displays the time set by the user. In addition, the keypad 13 preferably further includes an emergency shut-off key for allowing the user to arbitrarily cancel charging. This may be used when the user needs to use the electric vehicle urgently while charging the electric vehicle 5 or when a situation requiring inspection or repair of the electric vehicle 5 occurs. When the user selects the emergency cutoff key, the charging control unit 12 controls the power supply unit 11 to cut off the power flowing to the socket 11a. At this time, the keypad 13 is preferably disposed on the outer surface of the terminal box so that the user can conveniently use.

3 is a block diagram of a terminal box according to another embodiment of the present invention.

The illustrated embodiment includes a card reader 14, a keypad 13, a display device 18, a current detector 17, and a power meter 20, in which the power meter 20 is a terminal box. It may be inserted or disposed outside of the terminal box.

In the present embodiment, since the functions of the keypad 13, the display device 18, and the card reader unit 14 are the same as described with reference to FIG.

When the charging card is inserted into the card reader unit 14, the charging control unit 12 authenticates the inserted charging card, determines the remaining balance on the charging card, and determines whether or not charging is performed. When the balance remains on the charging card, the charging control unit 12 supplies the commercial alternating current to the socket 11a. The current detector 17 is connected in series between the socket 11a and the commercial AC input terminal. The current detector 17 detects a current of commercial alternating current (AC) output to the electric vehicle 5 through the socket 11a. When the battery of the electric vehicle 5 is being charged, the commercial alternating current output from the socket 11a is continuously supplied to the electric vehicle 5, so that a constant amount of current is continuously detected by the current detection unit 17.

On the other hand, when the charging of the battery is completed, the battery charging circuit built in the electric vehicle 5 cuts off the power provided from the socket 11a. In this case, the socket 11a is opened and the current flow is stopped, and the current is not detected by the current detector 17. therefore,

The charging control unit 12 determines the completion of charging of the battery according to whether the current detection unit 17 detects the current, or the amount of current detected by the current detection unit 17 is the amount of current in the open state of the socket 11a (hereinafter referred to as a reference value). In case of.), It is determined that the battery is fully charged.

When the amount of current detected by the current detector 17 is equal to or less than the reference value, the charging control unit 12 sets the time from the time when the charging of the electric vehicle 5 starts to less than the reference value as the charging section, and the power meter 20 The final power consumption, and the cost thereof, are calculated by multiplying the power consumption measured in the multiplied by the charging interval.

At this time, the charging control unit 12 calculates the final cost by referring to the electric charge of the time when the charging started and the completed time for the electric vehicle 5. The charging control unit 12 includes cost information for each time slot, and calculates a cost for each time interval when charging is performed. Here, of course, the cost of the charging control unit 12 is based on the electric charge of the region where the terminal box is located.

4 is a block diagram of a terminal box according to another embodiment of the present invention.

The illustrated embodiment is an embodiment in which the electric vehicle 5 and the terminal box charge electricity through separate dedicated cables, and the shape of the charging cable 6 of the electric vehicle 5 is connected to a conventional plug (commercial alternating current). The plug) is different in shape. This will be described with reference to FIGS. 5 and 6 together.

FIG. 5 shows a first embodiment of a cable dedicated to the electric vehicle 6 side, and FIG. 6 shows a second embodiment of a dedicated cable.

First, referring to FIG. 5, it can be seen that three terminals are shown at the end of the charging cable 6 of the electric vehicle 5. Reference numeral 3b and reference numeral 3c denote AC input terminals for AC input, and reference numeral 3c corresponds to a signal terminal. The signal terminal 3c is connected to the charging circuit of the electric vehicle 5 and provides the battery charging information output from the charging circuit to the socket 11a. In the dedicated cable shown in FIG. 5, three terminals 3a, 3b, and 3c protrude to the outside.

Next, referring to FIG. 6, three terminals 7a, 7b, and 7c are recessed inwards. Of the three terminals shown, reference numerals 7b and 7c correspond to AC input terminals, and reference numeral 7c corresponds to a signal terminal.

Referring back to FIG. 4,

The charging control unit 12 continuously monitors the state of charge of the battery through the signal terminals 3a or 7a of the dedicated cable shown in FIGS. 5 and 6. Through this, the charging control unit 12 may predict whether the battery is fully charged and when the charging is completed. The prediction result is displayed on the display device 38 so that the user can know when the electric vehicle is fully charged.

Preferably, the charging control unit 12 includes a charging time calculating unit 32a, a charging amount detecting unit 32c, and a charging processing unit 32b.

The charge amount detecting unit 32c detects the charge amount of the battery through the state information of the battery received through the signal terminal. The charging time calculating unit 32a continuously monitors the state information of the battery received through the signal terminal, and receives the charging completion time of the battery through the state information. When the charging processor 32b is notified of whether the battery is fully charged through the signal terminal, the charging processor 32b calculates the cost by multiplying the amount of power supplied from the time when the battery is powered to the time when the buffer is notified. At this time, the charging processing unit 32b performs charging for each section when charging the battery. That is, in regions where the cost of electricity differs according to the time zone in which electricity is used, the charge is discriminated according to the time zone.

Since the functions of the card reader 34 and the keypad 33 are the same as described above with reference to FIG. 2, redundant descriptions thereof will be omitted.

Figure 7 shows a block diagram of another embodiment of the present invention.

The illustrated embodiment is similar to the embodiment described with reference to FIG. 2, except that the card reader unit is an RFID method. Therefore, a description overlapping with that described in FIG. 2 will be omitted, and only the differences according to the RFID scheme will be discussed.

In the figure, the card reader 44 reads out the charging card or deducts the balance of the charging card according to the RFID method. The card reader unit 44 transmits radio waves toward the charging card 2, and the charging card 42 transmits card information to the card reader unit 44 in response to the radio waves. To this end, the charging card 42 has a circuit portion 43 coupled with the antenna. The circuit portion 43 embedded in the charging card 42 responds only to the radio waves transmitted from the card reader 44 and operates by using the radio waves transmitted from the card reader 44 as a driving power source. Of course, a separate driving battery may be built in the charging card 42 itself.

Accordingly, the power supply unit 41, the socket 41a, the power amount calculating unit 41b, the keypad 43, and the charging control unit 42 each include the power supply unit 11, the socket 11a, and the power amount calculating unit of FIG. 2. Corresponding to (11b), keypad 11, and charging control unit 12, respectively, the function is the same bar, overlapping description will be omitted.

The gist of the present embodiment implements a magnetic or electronically implemented charging card in a non-contact manner by incorporating RFID technology into the intelligent electric charging control system pursued by the present invention, so that the user can conveniently use the charging card. It makes sense.

8 conceptually illustrates an example of a socket connection method of a terminal box according to the present invention.

In the illustrated terminal box, the charging control unit 52 is connected to the plurality of power meters 51a to 51n, and the plurality of power meters 51a to 51n measure the measured value of the power applied to the electric vehicle from each socket 50a to 50n. The charging control unit 52 is provided. The charging control unit 52 calculates and charges the amount of power transmission for each socket 50a to 50n.

The illustrated embodiment extends the embodiment of each terminal box shown in FIGS. 2, 3, 4, and 7. Thus, the embodiments of FIGS. 2, 3, 4, and 7 are applicable to what is described with reference to FIG. 8, applying a plurality of sockets and power meters to each embodiment, and the charging described in each embodiment. The control unit may of course handle charging for each socket. As a result, a plurality of electric vehicles may charge by using one terminal box.

9 shows an example of a charging system using a terminal box of the present invention.

In the illustrated charging system, a plurality of terminal boxes 60a to 60e are wirelessly connected to the charging server 100. To this end, each terminal box (60a to 60e) should be equipped with a wireless communication module for wireless connection with the base station 200. The charging server 100 is connected to the terminal boxes 60a to 60e through the base station,

-A charging card is inserted into any one of the terminal boxes 60a to 60e, and each terminal box 60a to 60e determines the validity of the card information when transmitting the card information of the charging card.

-When the card information is valid, send a command to allow charging to the terminal box (any one of 60a to 60e) in which the charging card is inserted,

-Upon notification of the completion of charging in the terminal boxes (60a to 60e) in which the charge card is inserted, charges to the user's credit card company server 80, or the server 90 of the mobile communication company used by the user based on the card information. At this time, the charging server 100,

After calculating the cost by receiving the start of charging and completion of charging in the terminal boxes 60a to 60e, the credit card company server 80 or the mobile carrier server 90 may be charged.

It is possible to charge the charge to the credit card company server 80 or the mobile communication company server 90 by calculating the charging cost in the terminal boxes 60a to 60e and being notified only of the result.

If the charging server 100 calculates the charging cost, the charging server 100 calculates the charge by discriminating the cost according to the region where the terminal boxes 60a to 60e are arranged and the charging time in the terminal boxes 60a to 60e. do.

That is, the charging server 100 charges differently according to the positions of the terminal boxes 60a to 60e in consideration of the fact that the electric cost is different according to the region where electricity is produced.

The billing is performed hourly, taking into account the difference in electricity costs depending on the time of electricity generation.

In the figure, the charging server 100 and each terminal box 60a to 60e are connected to a wireless network. However, the charging server 100 and each terminal box 60a to 60e may be connected to a wired network, and the difference in the connection method does not significantly change the role of the charging server 100. If the charging server 100 and each terminal box 60a to 60e are connected through a wired network, the charging server 100 may add a charging cost to the cost of the user's mobile terminal through the server 90 of the mobile communication company. In addition, it is possible to charge the charging cost of the user through the credit card company server 80. This is only a difference according to a connection method, and thus, a separate drawing will not be described.

The type of the charging card and the read result are provided to the charging control unit 12.

The charging control unit 12 determines whether the card is allowed to use electricity through the card information provided from the card reader unit 14. As a result of the determination, in the case of a card which allows the use of electricity, the power supply unit 11 is controlled so that commercial AC may be output from the socket 11a. In addition, the charging control unit 12 opens the protective cover 11d to enable the user to insert the charging cable into the socket 11a.

The power meter 20 is provided between the power supply unit 11 and the socket 11a. The power meter 20 measures the power transmitted from the power supply unit 11 to the socket 11a, and the measurement result is provided to the charging control unit 12 through the power supply unit 11. The charging control unit 12 includes electricity cost information 12a for each time zone or region. Electricity cost information 12a divides 24 hours a day into several time intervals according to electricity rates, and records cost information for each time interval. The charging control unit 12 calculates an electricity usage fee by applying the electricity cost information 12a to the time period when the user uses electricity, and provides the charge through the socket 11a when the calculated usage fee reaches a cost initially set by the user. Allow power to be cut off.

This embodiment is an embodiment in which the user pays in advance the electricity bill to be used, the terminal box supplies power according to the cost paid by the user, and after the power corresponding to the cost paid by the user is transmitted, the power transmission is stopped. It is about. To do this,
