Can be. Here, the power may determine the instantaneous power, but is not limited thereto. In addition, the time series pattern is similar, but may be obtained by various modifications, for example, it may be obtained by referring to various factors such as reactive current, phase angle of reactive current, reactive power, active current, active power, and the like. will be.

In addition, the computing device 300 branches from one main power line to which the electricity meter 200 is coupled, and includes k charging terminals 100-1,?, And 100-k having an outlet to which a plug of an electric load can be coupled. It is possible to manage the amount of charging power used to charge the electric vehicle (ev) transmitted from and to support the charging of the electric vehicle (ev).

The charging terminals 100-1,?, 100-k and the computing device 300 constituting the above system will be described in detail as follows.

First, referring to FIGS. 2 and 3, according to an embodiment of the present invention, an electric vehicle may be formed by branching from one main power line to which an electricity meter is coupled and having k outlets and an outlet to which an electric load plug may be coupled. Charging terminal 100 to charge may include a detachable detection unit 110, authentication unit 120, voltage detection unit 130, control unit 140, power amount calculation unit 150 and power cut-off unit 160. have.

Detachable detection unit 110 detects that the plug of the electrical load is detached to the outlet (100c) formed in the charging terminal 100, for example, is formed in the groove area of the outlet is plug or detached to the outlet (100c) It may include a switch for issuing a switching signal in accordance with the operation to be attached. In addition, the detachable detecting unit 110 detects that the plug is detached or detached by an object sensor such as an infrared sensor or a laser sensor, or detects the unplugged or detached state of the plug through the illuminance sensor. You can also detect it.

In addition, the authenticator 120 may authenticate a user or support another device to perform user authentication in response to the input authentication information of the user. In this case, the user authentication information may be obtained from at least one of a magnetic card, an IC card, an RFID chip, and a user keypad input. The IC card and the magnetic card may be a credit card, a postpaid card, a prepaid card or the like including user identification information. The IC card or the RFID chip may perform authentication or payment in close proximity to the authentication unit 120, and the magnetic card may perform authentication or payment through the stripe reading unit. In addition, a user may input user identification information by pressing or touching a key of the keypad 121.

In this case, the charging terminal 100 may include a display 122, and may display information on the amount of charging power according to the authentication operation of the user and the charging of the electric vehicle through the display 122.

In addition, the voltage detector 130 detects the voltage of the power supplied from the main power line to which the wattmeter is coupled, and may be formed inside the charging terminal 100 or may be formed outside the charging terminal 100.

In addition, the controller 140 may perform signal processing in the charging terminal 100.

In addition, the power calculation unit 150 is determined to be attached to the plug of the electrical load in response to the signal of the detachable detection unit 110, by analyzing the time series pattern of the power supplied to the electrical load through the outlet (100c) As a result of checking whether the electric load is an electric vehicle or other equipment, when it is determined that the electric load is the electric vehicle, the electric power supplied to the electric vehicle is measured through the outlet 100c and the measured charging power amount is measured through the authentication unit 120. Matching and recording the information of the authenticated user, or by transmitting the amount of charging power matched to the user to the computing device may support to manage the amount of charging power transmitted from the at least one charging terminal separately from the amount of power used by the electricity meter. In this case, when it is determined that the time series pattern of the power supplied to the electric load is other equipment, the power amount calculation unit 150 does not measure the power supplied to the other equipment through the outlet 100c. Accordingly, by subtracting the amount of charging power used for charging the electric vehicle from the total amount of power used through the electricity meter, it is possible to separate the amount of charging power used by the electric vehicle and the amount of power used by other equipment. In this case, the amount of power used by the meter is not formed in the charging terminal, but may also include the amount of power used through the outlet installed by branching from the main power line to which the meter is coupled. In addition, the power amount calculation unit 150 transmits power information supplied to the electrical load through the outlet to the computing device, thereby allowing the computing device to obtain a time-series pattern of power by referring to the power information, and time-series of the obtained power. It may be possible to determine whether the electric load is an electric vehicle by checking whether the pattern matches the charging pattern of the electric vehicle.

In addition, the power amount calculation unit 150 performs the start and end of the measurement of the supply power for charging the electric vehicle in response to the signal of the detachable detection unit 110, the first power cut off pattern indicating the end of the supply power With reference to the metering can be performed until the first power cut pattern is detected. That is, when the user detects the first power blocking pattern for removing the charging plug of the electric vehicle from the outlet, it is determined that the charging of the electric vehicle by the user is completed, and thus the amount of charging power of the user can be calculated. In addition, the power amount calculating unit 150 temporarily cuts off the supply power when the second power cutoff pattern for temporarily blocking the supply power to detect the battery charging state is detected in the charging state of the electric vehicle. After temporarily shutting off the user information and the power supply and managing the user information after restarting the power supply again, the second power cutoff pattern is separated from the first power cutoff pattern. Supply power for charging can be metered. That is, the charging unit of the electric vehicle temporarily acquires a second power cutoff pattern to temporarily shut off the charging power to check the charging state of the battery, and then check the charging state of the battery and supply the charging power again. The calculation unit 150 determines that the second power cutoff pattern is not a signal for the completion of the charging of the electric vehicle, and determines that the charging is continuously performed, thereby preventing the problem such as miscalculation by continuously metering the supply power. .

In addition, the power amount calculation unit 150 is determined that the plug of the electric load is attached by the signal of the detachable detection unit 110, the electric load is an electric vehicle and the authentication completion signal for the user is transmitted from the authentication unit 120 When the electric power is supplied to the electric vehicle through the outlet, the metering is started. When the first power cutoff pattern is detected by the signal of the detachable detecting unit 110 and the plug of the electric load is determined to be detached, the outlet is disconnected. By terminating the measurement of the power supplied to the electric vehicle through the amount of power measured from the start to the end can be calculated as the amount of charging power corresponding to the user.

In addition, the power cut-off unit 160 cuts power supplied to the electric vehicle through the outlet 100c and may be formed inside the charging terminal 100 or may be formed outside the charging terminal 100.

After the voltage detected by the voltage detector 130 that detects the voltage of the power supplied from the main power line is obtained by the computing device, it is determined that the voltage detected by the voltage detector 130 is stepped down by a predetermined value or more. When the charging priority is set by the computing device, the specific power cutoff of the low priority of the at least one of the power cutoff units 160 is configured so that the step-down of the detected voltage is less than the set value. The specific charging terminal corresponding to the unit may block supplying power to the electric vehicle. Through this, the risk of overload due to the charging of the electric vehicle can be prevented in advance.

At this time, by the computing device, information of users who are charging the electric vehicle through individual charging terminals among the k charging terminals is confirmed, and when the charging priority of the identified users is analyzed and the charging priority is set, With reference to the charging priority, the specific charging terminal corresponding to the specific power interrupting unit corresponds to the specific power interrupting unit so that the specific power interrupting unit having the lower priority of at least one of the power interrupting units is less than the set value. It can cut off the power supply to electric vehicles. The electric vehicle charging pattern may include at least one of a start time, an end time, a time period for charging an electric vehicle for each user, a period for charging the electric vehicle for each user, and a charging rate for the electric vehicle for each user. That is, the priority of charging may be set by analyzing patterns such as a time and a time period during which the user mainly charges the electric vehicle, a time required for charging, and how much the electric vehicle is charged in a single charge.

In addition, when a cyclic charging rank, which is a relative rank set for individual charging terminals charging an electric vehicle among k charging terminals, is set by the computing device, a specific rank of the power cut-off unit is referred to with reference to the set cyclic charging rank. The at least one specific power cutoff unit may block the specific charging terminal corresponding to the specific power cutoff unit from supplying power to the electric vehicle so that the step-down of the detected voltage is less than the set value.

In addition, the power calculation unit 150 is determined to be attached to the plug of the electric load by the signal of the detachable detection unit 110, in the state that the electric load is confirmed that the electric vehicle, from the authentication unit 120 to the user If the authentication error signal is received or the authentication result signal for the user is not received from the authentication unit 120 for a predetermined time or more, the power cut-off unit 160 to cut off or cut off the power supplied to the electric vehicle through the outlet. Can support Through this, the electric power for charging the electric vehicle can be prevented from being used arbitrarily without management or charging.

In addition, the power amount calculation unit 150 is determined to be attached to the plug of the electric load by the signal of the detachable detection unit 100, the electric load is confirmed that the electric vehicle is a state of supplying power to the electric vehicle through the outlet At, when it is determined that the plug of the electrical load is detached by the signal of the detachment detecting unit 100, the user may support or transmit information corresponding to the detachment state of the plug. Through this, the user can confirm that the charging of the electric vehicle has been stopped by the third party instead of removing the charging plug in response to the completion of the charging of the electric vehicle.

Referring to the method of charging the electric vehicle through the k charging terminals according to an embodiment configured as described above are as follows.

The plug of the electrical load corresponds to a signal of the detachable detection unit 110 that detects that the plug of the electrical load is detached from the outlet 100c, and the plug of the electrical load is at least one of k charging terminals 100-1,?, 100-k. If it is determined that it is attached to the charging terminal, at least one charging terminal, by analyzing the time series pattern of the power supplied to the electrical load through the outlet (100c) to support or confirm whether the electrical load is an electric vehicle or other equipment. Can be.

That is, when the user attaches the plug to the outlet of the specific charging terminal in order to charge the electric vehicle, the specific charging terminal determines that the plug of the electrical load is attached to the outlet by the signal of the detachable detection unit 110, the electrical load Analyze the time series pattern of power supplied to the system. In this case, the time series pattern of the power may have a unique shape according to the electric load, through which it is possible to distinguish the power pattern of the charging power pattern of the electric vehicle and the other equipment which is another electric device.

In this case, the at least one charging terminal obtains a time series pattern of power by referring to at least one or more of a voltage, a current, and a power factor PF corresponding to the power supplied to the electric load, By checking whether the time series pattern matches the charging pattern of the electric vehicle, it is determined whether the electric load is the electric vehicle.

For example, as shown in Figure 4, when the electrical load is attached to the outlet by the signal of the detachable detection unit 110, the power amount calculation unit 150 within a first set time, for example after the electrical load is attached to the outlet Analyzing the power supplied to the electrical load within 2 to 3 seconds, to determine whether the power supplied through the outlet is a first set value, for example 50W or more (S10), by the signal of the detachable detection unit 110 The electrical load is attached to the outlet, and it is checked whether the power supplied to the electrical load is within a second set time, for example, within 5 seconds to 10 seconds, by a second set value, for example, 3,000 W or more (S11). Then, when the power supplied through the outlet is greater than or equal to the first set value within the first set time and greater than or equal to the second set value within the second set time, the power amount calculation unit 150 sets power to the second set value from the first set value. Check whether the power change slope of the section that is changed to the value is greater than or equal to the set slope value (S13). If the power change slope is greater than or equal to the set slope value, it is determined that the attached electric load is an electric vehicle (S13). If it is not more than the slope value, it is determined that the attached electric load is other equipment (S14). That is, at the start of charging of the electric vehicle due to the charging pattern characteristics of the electric vehicle, the battery charger of the electric vehicle conducts with low power, for example, about 50W, to check the connection of the external power supply. After the connection is confirmed, since the high power for charging the battery, for example, about 3,500W of power is used, by checking the initial charging pattern of the electric vehicle, the power calculation unit 150 checks whether the attached electric load is the electric vehicle. . At this time, the determination of whether the electric load is an electric vehicle was performed by the power amount calculating unit 150, but unlike this, by transmitting information on the power supplied through the outlet to the computing device, the computing device is attached to the outlet through power analysis. The electronic load may be determined to determine whether the electric load is an electric vehicle or other equipment, and information about the load thereon determined by the computing device may be obtained.

When it is determined that the electric load is an electric vehicle, the at least one charging terminal measures the power supplied to the electric vehicle through the outlet, records the measured charging power amount by matching the information of the authenticated user, or matches the user. The amount of charged power may be transmitted to the computing device to support the computing device to separately manage the amount of charging power transmitted from the at least one charging terminal from the amount of power used by the electricity meter. Through this, the charging terminal may separately manage and manage the amount of power for charging the electric vehicle and other equipment using the outlet of the charging terminal, and may also charge by separating the amount of charging power used for charging the electric vehicle.

At this time, the at least one charging terminal, in response to the signal of the detachable detection unit 110 performs the start and end of the metering of the power supply for charging the electric vehicle, the first power cut off pattern indicating the end of the supply power That is, the user performs weighing until the first power interruption pattern is detected by referring to the operation of detaching the charging plug of the electric vehicle from the outlet of the charging terminal, and in the state of charging of the electric vehicle, the electric vehicle charges the battery. If a second power interruption pattern is detected to temporarily shut off the supply power to check the status, the user information before temporarily shutting off the supply power and the power supply after the power supply is temporarily interrupted and then resumed again The user information is managed as the same, and the second power cutoff pattern is separated from the first power cutoff pattern. Supply power for charging can be metered.

That is, the at least one charging terminal is determined to be attached to the plug of the electric load by the signal of the detachable detection unit 110, when the electric load is an electric vehicle and the authentication completion signal for the user is transmitted, the electricity through the outlet Start metering the power supplied to the vehicle. When the first power cutoff pattern is detected by the signal of the detachment detecting unit 110 and the plug of the electric load is determined to be detached, the electric power supplied to the electric vehicle through the outlet is metered, and from start to end. By calculating the measured power amount as the charging power corresponding to the authenticated user, it is possible to prevent the charging power amount from being incorrectly metered or charged according to the first power interruption pattern due to a momentary short circuit for checking the battery condition of the electric vehicle. Will be.

In addition, at least one of the k charging terminals, it is determined that the plug of the electric load is attached by the signal of the detachable detection unit 110, the electric load is confirmed that the electric vehicle, the user If an authentication error signal is received or an authentication result signal for a user is not received for more than a set time, a challenge by an unauthorized third party can be prevented by helping to cut off or cut off the power supplied to the electric vehicle through the outlet. Will be.

In addition, at least one of the charging terminals of the k charging terminals, it is determined that the plug of the electric load is attached by the signal of the detachable detection unit 110, it is confirmed that the electric load is an electric vehicle to the electric vehicle through the outlet If it is determined that the plug of the electric load is detached by the signal of the detachment detecting unit 110 in the state of supplying power, the user may transmit or transmit information corresponding to the detachment state of the plug to the user. It can be seen that the charging plug has been detached by any third party.

In addition, after the voltage detected by the voltage detector 130 that detects the voltage of the power supplied from the main power line is obtained by the computing device, the voltage detected by the voltage detector 130 is stepped down to a set value or more. When it is determined that the charging priority is set by the computing device, the specific charging terminal having a lower priority of at least one of the k charging terminals is less than the set value of the voltage detected by referring to the set charging priority. In order to ensure that the electric vehicle can be powered off.

That is, by the computing device, information of the users who are charging the electric vehicle through the individual charging terminals among the k charging terminals is checked, and when the identified charging priority of the electric vehicle charging patterns is set, the charging priority is set. With reference to the priority, the specific charging terminal having a lower priority of at least one of k charging terminals may block supplying power to the electric vehicle so that the step-down of the detected voltage becomes less than a set value.

In addition, when a cyclic charging rank, which is a relative ranking set for individual charging terminals charging an electric vehicle among k charging terminals, is set by the computing device, a specific ranking of k charging terminals is referred to with reference to the set cyclic charging ranking. At least one specific charging terminal of the may prevent the supply of power to the electric vehicle so that the step-down of the detected voltage is less than the set value.

Next, referring to FIG. 5, an electric vehicle that is branched from one main power line to which an electricity meter is coupled according to an embodiment of the present invention and is transmitted from k charging terminals having an outlet to which a plug of an electric load is coupled may be formed. The computing device 300 that manages the amount of charging power used to charge and supports to charge the electric vehicle may include a communication unit 310 and a processor 320.

Can be obtained by matching. Also, the communication unit 310 charges at least one of the k charging terminals in a state in which it is determined that the plug of the electrical load is attached by the at least one charging terminal of the k charging terminals in response to the signal of the detachable part detecting unit. It is possible to obtain information of the power supplied to the electrical load from the terminal.

That is, at least one of the k charging terminals, the start and end of the measurement of the supply power for charging the electric vehicle is performed in response to the signal of the detachable detection unit, the first power indicating the end of the supply power The second power that causes the metering to be performed until the first power interruption pattern is detected with reference to the interruption pattern or when the electric vehicle temporarily cuts off the supply power to check the battery state of charge in the electric vehicle's state of charge. When the blocking pattern is detected, the second power cut-off pattern may be managed so that the user information before temporarily shutting off the supply power and the user information after restarting the power supply are managed as the same. In a state in which it is distinguished from the first power interruption pattern, the supply power for charging the electric vehicle is measured. A communication unit 310 acquires the quantity of charged electricity that matches the authenticated user and.

In addition, the processor 320 may separately manage the obtained amount of charging power from the amount of power used by the wattmeter.

That is, as shown in FIG. 6, the processor 320 distinguishes the charging power amount from the amount of power used by other equipment by subtracting the charging power amount for each user who charged the electric vehicle by using each charging terminal from the total power amount obtained by the electricity meter. Can be managed. In addition, the processor 320 may perform charging for each user or charge for the divided charging power amount. For example, each charging terminal charges a user authenticated with respect to the charging power used when charging the electric vehicle, and the computing device charges the charging power amount to the power provider, so that the power provider provides the total power amount of the electricity meter. Can support billing only for the amount of power excluding charge power.

In addition, the processor 320 determines that the plug of the electric load is attached in response to the signal of the detachable detecting unit, and when information of power supplied to the electric load through the outlet is obtained from the charging terminal through the communication unit, time series of power When the electric load is determined as the electric vehicle by analyzing the pattern, the amount of charging power supplied to the electric vehicle through the outlet of the at least one charging terminal among the k charging terminals is authenticated through the authentication unit of the at least one charging terminal among the k charging terminals.
