Description

Electric vehicle double charging prevention system using smart metering infrastructure and operation method thereof

The present invention relates to a system for preventing double charging of an electric vehicle using a smart metering infrastructure and an operating method thereof, and more particularly, to a system for preventing double charging of an electric vehicle using a smart metering infrastructure capable of preventing double charging during common charging of an electric vehicle and its operation it's about how

As the use of electric vehicles increases, the form of electric power charging is diversifying. In particular, due to the characteristics of electric vehicles that require a certain amount of time or more to charge electric power, electric vehicle charging in residential areas may increase. In this case, the electric vehicle is charged through a common outlet installed on the wall of an underground parking lot of an apartment building, or an outlet installed on an external wall or parking lot of a detached house.

There may also be cases where a visitor to a detached house charges his or her electric vehicle through an outlet. In this case, since problems such as progressive tax or electricity charge settlement due to electricity use occur, the visitor must be able to separately pay the charge for charging electricity.

On the other hand, even when the visitor separately pays for charging power, the meter of the detached house continues to run. In this case, the meter measures the total amount of electricity used by the detached house, including the amount of electric vehicle charging power. Therefore, there is a problem in that even though the electric charge for the electric vehicle charging power has already been paid, the owner of a detached house is charged twice.

The communication unit 240 may receive, from any one of the payment device and the payment server, payment information on the amount of charging power used for charging the electric vehicle in the single-family house.

When payment information is received during a predetermined period serving as a criterion for calculating the total electricity consumption, the controller 250 may correct the total electricity consumption and the total electricity rate.

Specifically, the control unit 250 may control the measurement unit 220 to perform a correction excluding the amount of charging power from the total power consumption.

In addition, the control unit 250 controls the billing unit 230 to calculate the overlapping charges already paid based on the amount of charging power and the electricity rate system of the single-family house, and to perform a correction excluding the overlapping charges from the total electricity rate. can

The controller 250 may specify a calibration target meter to be corrected for the total power consumption and the total electricity price, according to various embodiments of the present disclosure.

According to an embodiment, the controller 250 specifies a meter that measures the amount of charging power corresponding to the overlapping charge based on the information of the single-family house as the calibration target meter, and the total power consumption and total calculated by the calibration target meter. Electricity rates can be adjusted. To this end, the payment information may include information on the information of the single-family house in which the electric vehicle charging is performed, the amount of charging power and the payment amount, and the like.

According to another embodiment, the control unit 250 generates an electric vehicle power charging pattern by collecting and learning charging-related data of the electric vehicle, and when the change rate of the charging electric power over time matches the electric vehicle electric power charging pattern, the electric vehicle power charging pattern is measured One meter can be specified as a meter to be calibrated, and the total power consumption and total electricity bill calculated by the meter to be calibrated can be corrected. Here, the charging-related data may include at least one of a time required to be fully charged, an amount of charge per hour, an average voltage, an average amount of current, and a total amount of power.

According to another embodiment, the control unit 250 specifies a meter that measures the amount of charging power corresponding to the overlapping charge based on the unique number of the meter as the meter to be corrected, and the total power consumption and total power calculated by the meter to be corrected. Electricity rates can be adjusted. To this end, the payment information may include a unique number assigned to the meter corresponding to the detached house household in which the electric vehicle charging is performed.

On the other hand, according to the operating method of the intelligent smart metering infrastructure server 200 according to the present invention, storing information about a single-family house and a meter for measuring the electricity consumption of the single-family house in correspondence; and calculating the total power consumption of the single-family house by summing the power consumption for a predetermined period at every predetermined period; and calculating the total electricity rate based on the total electricity consumption and the electricity rate system of the single-family house, and imposing the total electricity rate on the single-family house. If payment information is received on the amount of charging power used for charging electric vehicles in single-family homes during Duplicate charges that have already been paid can be calculated, and a correction can be performed to exclude duplicate charges from the total electricity bill.

3 is a view for explaining an example in which the intelligent smart metering infrastructure server according to the present invention corrects the total power consumption and the total electricity rate.

When the calibration target meter 120 is specified, the intelligent smart metering infrastructure server 200 may correct the total power consumption and total electricity bill calculated by the calibration target meter 120 .

Specifically, the intelligent smart metering infrastructure server 200 may perform a correction excluding the amount of charging power from the total power consumption. In FIG. 3 , the total power consumption measured by the meter 120 is 100Kw, and the charging power is 20Kw. Therefore, the total power consumption after performing the correction becomes 80Kw.

The visitor has already paid for the 20Kw used to charge the electric vehicle. Therefore, the detached house 110 should be charged only for the final 80Kw except for the already paid 20kw from 100kw measured by the meter 120 .

To this end, the intelligent smart metering infrastructure server 200 calculates the already paid overlapping charges based on the amount of charging power and the electricity rate system of the single-family house, and performs correction by excluding the overlapping charges from the total electricity rate. .

Electricity companies set different electricity rates for each use as a result of policy, so the electricity rate system for home use and the electric rate system for electric vehicles are different. Therefore, even with the same amount of electric vehicle charging power, the electric charge in the case of being paid for the electric vehicle at the same time charging and the electric electric charge in the case of being included in the electric energy measured by the meter 120 later and paid as the household charge are different.

For example, it is assumed that the household electricity rate system is 200 won per 1 kW, and the electric rate system for electric vehicles is 100 won per 1 kW. Referring to FIG. 3 , the power used inside the detached house 110 is 80Kw, and the power used to charge the electric vehicle is 20Kw. In this case, if the electric charge for 20Kw is paid immediately after charging the electric vehicle, the electric rate system for electric vehicles is applied and becomes 2,000 won (20Kw X 100 won/1Kw). On the other hand, if the electricity rate for 20Kw is included in the total power consumption of the detached house 110 measured by the meter 120 and paid later, the household electricity rate system is applied and 4,000 won (20Kw X 200 won/1Kw) is applied. do.

In order to solve this problem, in the present invention, the intelligent smart metering infrastructure server 200 calculates the overlapped charge already paid based on the amount of charging power and the electricity tariff system of the single-family house, and excludes the overlapped charge from the total electricity bill. Perform calibration. That is, when calculating the overlapping rate, the electricity rate system for single-family houses, that is, the household electricity rate system, is applied instead of the electric rate system for electric vehicles, and the overlapping rate is calculated as 4,000 won (20Kw X 200 won/1Kw). After that, the total electricity bill is calculated as 16,000 won (80Kw X 200 won/1Kw) excluding 4,000 won (20Kw X 200 won/1Kw) from 20000 won (100Kw X 200 won/1Kw).

That is, in the present invention, the overlapping rate means the electricity rate that the householder of a single-family house is charged twice, so it should be calculated by applying the household electricity rate system to the electricity consumption that has already been paid.

4 is a view for explaining an example in which the intelligent smart metering infrastructure server according to the present invention specifies a meter to be calibrated.

The intelligent smart metering infrastructure server 200 may specify a meter to be calibrated based on the unique number of the meter. Here, the meter to be corrected may be a meter that measures the amount of charging power corresponding to the overlapping charge.

Referring to FIG. 4 , a meter 120 is installed correspondingly to the household of the detached house 110 , and a unique number assigned to the meter 120 is C1213 . The visitor charges the electric vehicle using the charging cable 140 having a payment function, and then contacts the card 160 to the payment device 150 attached to the charging cable 140 to pay the electricity bill. At the time of payment, the visitor inputs C1213, which is a unique number of the meter 120 .

The payment device 150 transmits payment information and a unique number C1213 of the meter 120 to the intelligent smart metering infrastructure server 200 . According to an embodiment, the payment device 150 may transmit identification information (lot number, dong, and number) of the detached house household corresponding thereto instead of the unique number of the meter 120 to the intelligent smart metering infrastructure server 200 .

The intelligent smart metering infrastructure server 200 may store information about the single-family house 110 household and the meter 120 measuring the electricity consumption of the single-family house 110 household in correspondence. In this case, identification information of the meter 120 corresponding to identification information of the detached house 110 household may be generated and managed in the form of a database 400 .

Referring to FIG. 4 , the intelligent smart metering infrastructure server 200 receives the identification number C1213 of the meter 120 together with payment information. In this case, after correcting the total power consumption and total electricity price of the meter 120 having the identification number C1213, and searching the detached house C corresponding to the identification number C1213 of the meter 120 by referring to the database 400, The corrected total electricity consumption and total electricity rates are notified to house C.
