무료로 충전한 전기를 방전하여 매전하는 행위는 불법 행위이므로, 전기차 또는 충전기에 탑재된 제어부를 통해 전기차에 충전 및 방전시의 데이터를 모두 기록하여 서버에 제공하여 관리하고, 이러한 관리 데이터를 통해 방전시 주행시에 우선 사용되도록 판단하고 관리할 수 있다. Since the act of discharging and selling electricity charged for free is an illegal act, record all data during charging and discharging of an electric vehicle through the control unit installed in the electric vehicle or charger, provide it to the server for management, and manage the discharge through this management data. It can be determined and managed so that it is used first during city driving.

도 1은 본 발명의 전력 관리 시스템을 도시한 블록도이다.1 is a block diagram illustrating a power management system of the present invention.

도 1을 참조하면, 전력 계통(100)(발전소 또는 한국전력)으로부터 배전부(110)를 통해 각 가정집(200) 및 공장(300)에 전력이 공급될 수 있다. Referring to FIG. 1 , power may be supplied to each house 200 and factory 300 from a power system 100 (power plant or KEPCO) through a power distribution unit 110 .

예를 들어 공장(300)을 제1 공장(310)과 제2 공장(320)으로 설명하면, 가정집(200) 및 각 공장에는 전력 사용량을 과금할 수 있는 계량기(202)(312)(322)가 갖추어질 수 있다. 가정집(200) 및 공장(300)에 공급되는 전기 요금은 다르게 책정될 수 있다. For example, if the factory 300 is described as the first factory 310 and the second factory 320, the household 200 and each factory have meters 202, 312, and 322 capable of charging power consumption can be equipped. Electricity rates supplied to the household 200 and the factory 300 may be set differently.

개인은 충전만 가능하고 전기를 방전하여 역송하여 전기를 판매하는 매전 행위를 할 수 없고, 사업자만이 할 수 있다. 사업자는 한국전력, 구역 전기 사업자, 수요 관리 사업자가 될 수 있다. Individuals can only charge and cannot sell electricity by discharging and sending electricity back, only businesses can do so. Operators can be KEPCO, district electric operators, and demand management operators.

또한, 전기를 사용하는 전기차(400)는 충전기(500)를 통해 전기를 충전할 수 있고, 별도 마련된 서버(600)와 통신을 통해 전기차(400)에 대한 제반 정보를 서버(600)에 제공할 수 있다. In addition, the electric vehicle 400 using electricity can be charged with electricity through the charger 500, and can provide various information about the electric vehicle 400 to the server 600 through communication with the server 600 provided separately. can

따라서, 전기차(400)가 법인 차량인지 개인 소유 차량인지 여부 등을 서버(600)에 차량 ID를 통해 등록해둘 수 있다. 예를 들어, 제어부는 차량 ID가 법인 차량의 차량 ID이면 역송이 불가능하다고 판단하고, 개인 소유 차량의 차량 ID이면 역송이 가능하다고 판단할 수 있다. 태깅 정보는 차량 ID를 포함할 수 있고, 태깅 정보에 따라 역송 가능성이 판단될 수 있다.Therefore, whether the electric vehicle 400 is a corporate vehicle or an individual vehicle can be registered in the server 600 through the vehicle ID. For example, if the vehicle ID is a vehicle ID of a corporate vehicle, the control unit may determine that reverse transport is impossible, and may determine that reverse transport is possible if the vehicle ID is a vehicle ID of an individual vehicle. The tagging information may include a vehicle ID, and the possibility of reverse delivery may be determined according to the tagging information.

전기차(400)의 전기 소모 형태는 자연 방전, 주행에 의한 소모, 매전에 의한 소모로 이루어질 수 있다. Electricity consumption of the electric vehicle 400 may include natural discharge, driving consumption, and electricity consumption.

여기서, 본 발명은 전기차(400)에 전기를 충전 및 방전시 기록하여 관리할 수 있다. 가정집(200)에서 개인 소유 충전기를 통하여 충전된 전기차는 제2 공장(320)으로 이동하여 유료 충전 또는 유료 충전량에 관한 태깅 정보에 따라 전력 계통(100) 또는 배전부(110)로 전력이 역송될 수 있다. 역송 여부는 태깅 정보에 따라 판단될 수 있고, 서버는 하드웨어 또는 소프트웨어의 동작 권한을 가질 수 있다. 제어부에서 판단된 역송 가능 정보는 서버에 입수되고 서버의 권한으로 전력 역송에 관한 하드웨어 및 소프트웨어 동작이 차단될 수 있다.Here, the present invention can record and manage electricity when charging and discharging the electric vehicle 400 . The electric vehicle charged through the personal charger at the house 200 moves to the second factory 320, and power is sent back to the power system 100 or the power distribution unit 110 according to paid charging or tagging information on the paid charging amount. can Whether or not to send back may be determined according to tagging information, and the server may have hardware or software operation rights. The backtransportability information determined by the control unit is acquired by the server, and hardware and software operations related to power backtransmission may be blocked under the authority of the server.

즉, 전기차(400)에 전기 충전시 태깅 정보를 다음과 같이 설정할 수 있다. That is, when charging the electric vehicle 400, tagging information may be set as follows.

제1 항목은 유료 충전, 제2 항목은 무료 충전, 제3 항목은 유료 충전 장소, 제4 항목은 충전 시간, 제5 항목은 유료 충전량, 제6 항목은 차량 ID가 될 수 있다. 태깅 정보는 이들 중 적어도 하나에 관한 것일 수 있다. The first item may be paid charging, the second item may be free charging, the third item may be a paid charging location, the fourth item may be a charging time, the fifth item may be a paid charging amount, and the sixth item may be a vehicle ID. Tagging information may relate to at least one of these.

제1 항목 내지 제6 항목 중 적어도 하나를 포함하는 태깅 정보를 체크하고 관리할 수 있는 제어부(420)를 포함할 수 있다. 제어부(420)는 전기차, 충전기 중 적어도 하나에 마련될 수 있다. 서버는 제어부(420), 전력 계통(100), 배전부(110), 계량기(202)(312)(322) 중 적어도 하나와 통신하고, 태깅 정보를 교환할 수 있다. 서버의 지령에 따라 제어부(420), 전력 계통(100), 배전부(110), 계량기(202)(312)(322) 중 적어도 하나의 충전 또는 방전 여부가 결정될 수 있다.A control unit 420 capable of checking and managing tagging information including at least one of the first to sixth items may be included. The control unit 420 may be provided in at least one of an electric vehicle and a charger. The server may communicate with at least one of the controller 420, the power system 100, the power distribution unit 110, and the meters 202, 312, and 322 and exchange tagging information. Whether to charge or discharge at least one of the control unit 420, the power system 100, the power distribution unit 110, and the meters 202, 312, and 322 may be determined according to a command from the server.

본 발명은 전기차(400)의 충전 잔량(SOC)과 전기차(400)의 과거 이력을 포함하는 태깅 정보를 보고 역송 가능 여부를 판단하는 것에 특징이 있는 것으로서, 다음 표 1과 같이 예를 들어 설명한다. The present invention is characterized by determining whether or not to send back by looking at tagging information including the remaining charge (SOC) of the electric vehicle 400 and the past history of the electric vehicle 400, and will be described as an example as shown in Table 1 below. .

날짜date 충전량amount of charge 유료/무료 여부Paid/Free 역송 가능여부Whether back delivery is possible 역송 가능
방전량back delivery possible
amount of discharge 1월 1일January 1st 1010 유료pay 가능possible 55 1월 2일January 2nd 88 무료free 불가능impossible 00 1월 3일January 3rd 66 무료free 불가능impossible 00

표 1에서 1월 1일에 10만큼 충전하고, 1월 2일에는 8, 1월 3일에는 6을 충전한 경우, 10은 유료, 나머지 8,6은 무료 충전이면 10은 역송 가능하고 나머지는 불가능할 수 있다. In Table 1, if you charge 10 on January 1st, charge 8 on January 2nd, and charge 6 on January 3rd, 10 is paid, and the remaining 8,6 are free, 10 can be sent back and the rest It can be impossible.

표 1은 이러한 충전 내역 상태를 제어부(400)에서 태깅 정보할 수 있다. In Table 1, the control unit 400 may provide tagging information for such charging details.

역송 가능한 전력은 역송할 수 있는 상태이고, 나머지 무료 충전한 전력인 8,6은 역송할 수 없는 상태일 수 있다. The power that can be transported back is in a state that can be transported back, and the remaining free charged power 8 and 6 may be in a state that cannot be transported back.

이런 상태에서, 시간이 경과하여 2월 1일에 해당 전기차(400)의 충전 잔량(SOC)이 50이 되었다고 하면, 50은 1월 1일부터 2월 1일까지 충전하고 방전(전기차 주행에 따른 방전)하고 남은 잔량이고, 이러한 충전 잔량을 제1 기준값이라고 정의하고, 표 1에서 역송 가능한 전력인 10을 제2 기준값이라고 정의하면, 제어부(420)에서는 제1 기준값과 제2 기준값을 비교하여 제1 기준값이 제2 기준값보다 크면 역송하고, 제1 기준값이 제2 기준값보다 작으면 역송할 수 없다. In this state, assuming that the remaining charge (SOC) of the electric vehicle 400 becomes 50 on February 1st as time elapses, 50 is charged and discharged from January 1st to February 1st (according to the driving of the electric vehicle If the remaining amount after discharge) is defined as the first reference value, and 10, which is the power that can be transmitted back in Table 1, is defined as the second reference value, the control unit 420 compares the first reference value and the second reference value to determine the first reference value. If the first reference value is greater than the second reference value, it is returned, and if the first reference value is less than the second reference value, it cannot be returned.

만일, 충전 잔량이 5인 경우, 이를 제3 기준값이라고 정의하면, 제3 기준값이 제2 기준값과 비교한 결과, 제3 기준값이 제2 기준값보다 작으므로, 충전 잔량 5 모두를 역송 가능한 것으로 판단할 수 있다. If the remaining charge amount is 5, if this is defined as the third reference value, as a result of comparing the third reference value with the second reference value, the third reference value is smaller than the second reference value, so it can be determined that all of the remaining charge amount 5 can be sent back. can

다시 말해서, 역송 가능한 유료 충전량을 먼저 역송를 통해 소모시키고, 나머지 무료 충전량은 전기차의 주행에 의해 소모시킬 수 있다. In other words, the paid charging amount that can be transported back can be consumed first through back transporting, and the remaining free charging amount can be consumed by driving the electric vehicle.

본 발명은 도전 방지가 가능한 전력 관리 방법이 제공될 수 있다. The present invention may provide a power management method capable of preventing conduction.

본 발명의 전력 관리 방법은 전기차(400)에 전기를 충전하는 제1 단계; 상기 제1 단계후 태깅 정보가 유료 충전인지 무료 충전인지 여부를 파악하는 제2 단계; 제2 단계에서 유료 충전인 경우, 상기 전기차의 충전 잔량과 비교하여 유료 충전량이 충전 잔량보다 작으면 전기를 역송하는 제3 단계를 포함할 수 있다. The power management method of the present invention includes a first step of charging the electric vehicle 400 with electricity; a second step of determining whether the tagging information is paid or free charging after the first step; In the case of paid charging in the second step, a third step of retransmitting electricity may be included if the paid charging amount is smaller than the remaining charging amount compared to the remaining charging amount of the electric vehicle.

태깅 정보은 충전 장소 또는 충전 시간을 포함할 수 있다. Tagging information may include a charging place or a charging time.

이와 같이 본 발명은 전기차(400)의 충전 내역중 유료 또는 무료 충전 상태를 파악하고, 충전 잔량중 유료 충전량은 역송 가능하고 나머지 무료는 역송하지 못하고 주행을 통해 소모할 수 있게 되며, 전기차(400)에 탑재된 제어부(420)에서 이를 판단하고, 판단한 데이터를 서버(600)에 통신을 통해 제공해줄 수 있다.As such, the present invention identifies the paid or free charging status among the charging details of the electric vehicle 400, and among the remaining charging amounts, the paid charging amount can be sent back, and the remaining free charge can be consumed through driving without being able to be sent back, and the electric vehicle 400 The control unit 420 mounted on may determine this and provide the determined data to the server 600 through communication.

따라서, 본 발명은 표 1에서 유료로 충전한 전기 충전량인 10을 역송하고 남은 전기는 무료 충전한 것이므로, 전기차(400)의 주행을 통해 모두 소모하게 할 수 있다. Therefore, in the present invention, since 10, which is the amount of electricity charged for a fee in Table 1, is returned and the remaining electricity is charged for free, it can be consumed through the driving of the electric vehicle 400.

서버(600)에서는 이러한 등록된 전기차(400)의 모든 태깅 정보을 통해 역송 가능여부를 판단한 결과를 저장 및 관리할 수 있고, 그에 따라 도전 행위를 방지할 수 있다. The server 600 can store and manage the result of determining whether or not to send back through all the tagging information of the registered electric vehicle 400, thereby preventing a challenge.
