Description

휴대용 배터리 충전 시스템Portable battery charging system
본 발명은 사용한 휴대용 배터리를 반납하고 완충된 휴대용 배터리로 교체하는 충전 시스템에 관한 것이다. The present invention relates to a charging system for returning a used portable battery and replacing it with a fully charged portable battery.

Recently, with the rise of environmental problems, attention is focused on the means of transportation powered by electricity, away from the existing internal combustion engine that operates the engine by burning oil. Electric vehicles (EVs), which are electric-powered vehicles, have appeared in various ways, such as electric motorized kickboards and electric motorcycles, in addition to electric vehicles in the form of passenger cars.
이러한 전기 자동차는 친환경 적이고 유지비용이 적게 드는 장점 및 내연기관을 생략하여 이동수단의 무게 및 부피를 줄일 수 있는 장점 등이 있으나, 가장 큰 문제는 배터리의 충전 시간이 문제가 된다. 석유는 주유소에서 몇 분만에 주유할 수 있으나, 전기차의 배터리는 완충을 위해서는 최소 몇 십 분에서 몇 시간이 소요될 수 있다. Such electric vehicles have advantages such as eco-friendly and low maintenance cost and an advantage of reducing the weight and volume of the vehicle by omitting the internal combustion engine, but the biggest problem is the charging time of the battery. Petroleum can be refueled at a gas station in minutes, but batteries in electric vehicles can take at least several tens to hours to fully charge.
배터리의 충전시간은 전기차의 상용화에 큰 걸림돌이 되고, 가솔린 엔진을 포함하는 내연기관과 전기모터를 동시에 구비한 하이브리드 자동차 등이 오히려 전기차보다 선호되고 있는 실정이다.The charging time of the battery is a major obstacle to the commercialization of the electric vehicle, and a hybrid vehicle including an internal combustion engine including a gasoline engine and an electric motor is preferred to the electric vehicle.

최근 전기 자동차(40)가 상용화 되면서 전기 자동차(40)를 이용하고 있는 인구가 증가하고 있다. 전기 자동차(40)도 승용차 형태뿐만 아니라 오토바이나 전동 킥보드, 전동 자전거 등 그 형태가 다양해지고 있다. 다만, 충전시간이 일반 내연기관 자동차(40)의 주유시간보다 오래 걸리는 문제 때문에 사용의 불편함을 호소하는 사용자가 많아, 전기 자동차(40)의 보급에 큰 걸림돌이 되고 있다. As the electric vehicle 40 is commercialized recently, the population using the electric vehicle 40 is increasing. The electric vehicle 40 also has various forms such as motorcycles, electric kickboards, electric bicycles, as well as passenger cars. However, due to the problem that the charging time takes longer than the fueling time of the general internal combustion engine vehicle 40, many users complain of inconvenience of use, which is a great obstacle to the spread of the electric vehicle 40.
본 발명은 이러한 문제를 해소하기 위해 교체가능한 충전 배터리(30)를 이용한 전기 자동차(40)를 고려할 수 있다. 사용하던 배터리(30)를 반납하고 대신에 충전이 완료된 배터리(30)를 받아 다시 장착하여 별도의 충전시간을 절약할 수 있다. 제품마다 다른 규격의 휴대용 배터리(30)를 이용하는 경우, 교환이 용이하지 않으므로 범용성을 위해 AA건전지나 AAA건전지와 같이 규격화된 휴대용 배터리(30)를 이용할 수 있다. The present invention may consider an electric vehicle 40 using a replaceable rechargeable battery 30 to solve this problem. Returning the used battery 30, and instead of receiving the battery 30 is completed to charge it is possible to save a separate charging time. In the case of using a portable battery 30 having a different standard for each product, since it is not easy to replace, a standardized portable battery 30 such as an AA battery or an AAA battery may be used for versatility.
도 1은 본 발명의 휴대용 배터리(30)의 동작을 설명하기 위한 도면이다. 배터리(30) 하나의 크기가 너무 크면 교체 시 사람의 힘으로 장착 및 탈착이 어려운 문제가 있는 바, 너무 무겁거나 크지 않은 사이즈로 제조할 수 있다. 다만, 큰 용량의 전원이 필요한 경우에는 복수개의 배터리(30)를 이용할 수 있다. 1 is a view for explaining the operation of the portable battery 30 of the present invention. If the size of the battery 30 is too large, there is a problem that it is difficult to install and detach by a human force when replacing, it can be manufactured in a size not too heavy or too large. However, when a large capacity power source is required, a plurality of batteries 30 may be used.
즉, 도 1에 도시된 바와 같이, 전동 킥보드는 하나의 배터리(30)를 이용할 수 있고, 그 보다 큰 전동 오토바이는 2개의 배터리(30)를 전기차와 같이 크기가 큰 경우 3개 이상의 배터리(30)를 이용하는 방식으로 활용할 수 있다. That is, as shown in FIG. 1, the electric kickboard may use one battery 30, and a larger electric motorcycle may have three or more batteries 30 when two batteries 30 are large in size, such as an electric vehicle. ) Can be used.
휴대용 배터리(30)는 전기 자동차(40)에 단순히 전원을 공급하기만 하는 것이 아니라 전기 자동차(40)로부터 동작전압에 대한 정보를 받아 이를 기초로 레귤레이터의 출력전압을 조정하여 전기 자동차(40)에 전원을 공급할 수 있다. 전기 자동차(40)로부터 동작전압에 대한 정보는 전원 단자 이외에 추가적으로 데이터 단자를 이용하여 전송받을 수 있으나, NFC와 같이 근거리 무선통신 방식을 이용하여 정보를 수신할 수도 있다. 휴대용 배터리(30)의 외측으로 노출되는 단자의 개수가 많으면 내구성에 문제가 있기 때문에 무선통신 방식을 이용할 수 있다. 충전과 방전을 복수회 가능하도록 리튬이온 배터리(30)셀을 이용할 수 있으며, 충방전이 가능한 배터리(30) 셀이라면 리튬이온 이외의 소재를 이용할 수 있다. 휴대용 배터리(30)와 관련하여 전기 자동차(40)에 이용되는 경우만 설명하였으나, 자동차(40) 이외의 전자장치에도 이용될 수 있다. The portable battery 30 not only supplies power to the electric vehicle 40 but also receives information on the operating voltage from the electric vehicle 40 and adjusts the output voltage of the regulator based on the information to the electric vehicle 40. Can supply power. Information about the operating voltage from the electric vehicle 40 may be transmitted using a data terminal in addition to the power terminal, but may also receive information using a short range wireless communication method such as NFC. When the number of terminals exposed to the outside of the portable battery 30 is large, there is a problem in durability, so a wireless communication method may be used. A lithium ion battery 30 cell may be used to enable charging and discharging a plurality of times, and a material other than lithium ion may be used as long as the battery 30 cell is capable of charging and discharging. Although only the case of using the electric vehicle 40 in relation to the portable battery 30 has been described, it may be used in an electronic device other than the vehicle 40.
도 2는 본 발명의 휴대용 배터리(30)를 도시한 도면으로 일측에는 충전 및 방전을 위한 단자가 있고 손쉽게 탈착하기 위해 손잡이를 포함할 수 있다. 또한, 일 방향으로 길게 형성하여 휴대용 배터리(30)를 장착하기 위해 외측으로 노출되는 입구의 크기를 최소화 할 수 있다. 휴대용 배터리(30)의 단부에는 충전 및 방전을 위한 +단자(33) -단자(32)가 있고, 필요한 경우 데이터의 전송을 위한 단자를 더 포함할 수도 있다. 휴대용 배터리(30)를 충전 스테이션(20) 또는 전기 자동차(40)에 장착 시 특정 방향으로만 장착해야 하는 불편함을 최소화 하기 위해 정사각 기둥이나 원기둥과 같이 대칭적인 형태를 가지는 것이 바람직하다. 2 is a view showing a portable battery 30 of the present invention, one side has a terminal for charging and discharging and may include a handle for easy removal. In addition, it can be formed long in one direction to minimize the size of the inlet exposed to the outside for mounting the portable battery 30. The end of the portable battery 30 has a + terminal 33-a terminal 32 for charging and discharging, and may further include a terminal for transmitting data if necessary. When the portable battery 30 is mounted to the charging station 20 or the electric vehicle 40, it is preferable to have a symmetrical shape such as a square pillar or a cylinder in order to minimize inconvenience of mounting the portable battery 30 only in a specific direction.
도 3은 본 발명의 휴대용 배터리(30)를 전기 자동차(40)에 장착한 태양을 도시한 도면으로 건전지를 삽입하듯이 덮개(46)를 열어 전기 자동차(40)의 단자(43)과 휴대용 배터리(30)의 단자(32,33)이 맞닿도록 삽입할 수도 있고, 길이방향으로 삽입할 수도 있다. 전기 자동차(40)는 내연기관이 없어 떨림이 크지는 않으나 움직이는 장치이므로 충격에 의한 파손을 방지하고자 벽면에 충격흡수체(47)를 포함할 수 있다. 또한, 휴대용 배터리(30)는 전기 자동차(40)로부터 탈착 가능하므로 도난의 우려가 있어 잠금장치(34, 44)를 구비할 수 있다. 3 is a view showing an embodiment in which the portable battery 30 of the present invention is mounted on the electric vehicle 40. As shown in the drawing, the cover 46 is opened to open the terminal 43 of the electric vehicle 40 and the portable battery. The terminals 32 and 33 of 30 may be inserted in abutting manner or may be inserted in the longitudinal direction. Since the electric vehicle 40 has no internal combustion engine, the vibration is not large, but the moving device may include a shock absorber 47 on the wall to prevent damage caused by the impact. In addition, since the portable battery 30 is detachable from the electric vehicle 40, there is a risk of theft, and thus the portable battery 30 may include locking devices 34 and 44.
도 4는 본 발명의 휴대용 배터리 충전 시스템(1)의 개요도이다. 휴대용 배터리 충전 시스템(1)은 크게 휴대용 배터리(30)를 충전하는 충전 스테이션(20), 충전 스테이션(20)을 관리하는 서버(10) 및 서버(10)로부터 충전 스테이션(20)의 정보를 제공받고 휴대용 배터리(30)를 예약하는 사용자 단말기(50)로 구성된다. 4 is a schematic diagram of a portable battery charging system 1 of the present invention. The portable battery charging system 1 provides information of the charging station 20 from the charging station 20, the server 10 managing the charging station 20, and the server 10, which largely charges the portable battery 30. And a user terminal 50 that reserves the portable battery 30.
충전 스테이션(20)은 도 4에 도시된 바와 같이 여러 지역에 나누어 복수개를 구비할 수 있으며, 충전 스테이션(20)은 휴대용 배터리(30)가 삽입되는 복수개의 수용부를 포함한다. 탈착이 용이하도록 손잡이 부분이 외측으로 드러나도록 배치될 수 있으며, 길이방향으로 삽입하여 충전 스테이션(20)의 전면의 면적 대비 많은 휴대용 배터리(30)를 수용할 수 있다. 충전 스테이션(20)은 디스플레이부나 사용자 입력부를 포함하며 사용자는 이를 통해 스스로 충전 스테이션(20)에서 휴대용 배터리(30)를 교체할 수 있다. As shown in FIG. 4, the charging station 20 may be divided into several regions, and the plurality of charging stations 20 may include a plurality of receiving portions into which the portable battery 30 is inserted. The handle portion may be disposed to be exposed to the outside to facilitate detachment, and may be inserted in the longitudinal direction to accommodate a large number of portable batteries 30 relative to the area of the front surface of the charging station 20. The charging station 20 includes a display unit or a user input unit, through which the user can replace the portable battery 30 in the charging station 20 by themselves.
서버(10)는 복수개의 충전 스테이션(20)으로부터 충전 스테이션(20)에 수용된 휴대용 배터리(30)의 배터리 정보 및 충전 스테이션(20)의 상태정보를 받을 수 있으며, 사용자 단말기(50)로부터 휴대용 배터리(30)의 예약이 있는 경우 사용자의 요청에 부합하는 충전 스테이션(20)에 예약 정보를 전송한다. 사용자는 월정액 또는 교체 횟수에 따른 과금 방식을 통해 휴대용 배터리(30)를 교환할 수 있다. 서버(10)는 사용자의 요청이 있는 경우, 사용자의 위치를 기반으로 완충된 휴대용 배터리(30)를 보유하고 있는 충전 스테이션(20)에 대한 정보를 제공할 수 있다. The server 10 may receive the battery information of the portable battery 30 accommodated in the charging station 20 and the status information of the charging station 20 from the plurality of charging stations 20, and the portable battery from the user terminal 50. If there is a reservation of 30, the reservation information is transmitted to the charging station 20 corresponding to the request of the user. The user may exchange the portable battery 30 through a monthly fee or a charging method according to the number of replacements. When requested by the user, the server 10 may provide information about the charging station 20 having the portable battery 30 fully charged based on the location of the user.
보다 구체적인 내용은 이하의 도면을 참고하여 설명하도록 한다. More details will be described with reference to the drawings below.
도 5는 본 발명의 휴대용 배터리 충전 시스템(1)의 동작을 설명하기 위한 흐름도이다. 도 6는 본 발명의 휴대용 배터리 충전 시스템(1)의 충전 전류 결정을 위한 메커니즘을 도식화한 도면이다. 5 is a flowchart for explaining the operation of the portable battery charging system 1 of the present invention. 6 is a diagram illustrating a mechanism for determining the charging current of the portable battery charging system 1 of the present invention.
사용자 단말기(50)와 서버(10) 그리고 충전 스테이션(20) 및 휴대용 배터리(30)가 객체로 존재하고 각 객체 사이에 작용을 통해 휴대용 배터리 충전 시스템(1)이 동작한다. 먼저 휴대용 배터리(30)를 충전스테이션(20)에 사용자가 삽입하면 충전 스테이션(20)은 휴대용 배터리(30)로부터 배터리 정보를 제공받는다(S110). 도 6에 도시된 바와 같이 배터리 정보는 배터리(30)의 충방전 횟수, 배터리(30) 자체의 온도, 충전전류 기록 및 방전전류 기록 그리고 배터리(30) 잔량 등을 포함할 수 있다. 휴대용 배터리(30) 자체에 메모리를 포함하여, 사용자가 휴대용 배터리(30)를 사용할 때의 환경(방전 전류, 방전 횟수 등) 정보를 기록할 수 있으며, 충전 스테이션(20)은 이 정보를 휴대용 배터리(30)로부터 받아 서버(10)로 전송할 수 있다(S130). The user terminal 50, the server 10, the charging station 20, and the portable battery 30 exist as objects, and the portable battery charging system 1 operates through actions between the objects. First, when a user inserts the portable battery 30 into the charging station 20, the charging station 20 receives battery information from the portable battery 30 (S110). As shown in FIG. 6, the battery information may include the number of charge / discharge cycles of the battery 30, the temperature of the battery 30 itself, the charge current record and the discharge current record, and the remaining amount of the battery 30. Including the memory in the portable battery 30 itself, it is possible to record the environment (discharge current, discharge number, etc.) information when the user uses the portable battery 30, the charging station 20 is a portable battery Received from the 30 can be transmitted to the server 10 (S130).
휴대용 배터리(30)의 메모리의 크기를 고려하여 서버(10)에 송신된 정보는 삭제하고 추후 필요시 서버(10)로부터 충전 스테이션(20)이 전송 받아(S120) 휴대용 배터리(30)로부터 받은 새로운 정보와 서버(10)로부터 받은 배터리 정보를 취합하여 수용부에 삽입된 휴대용 배터리(30)의 충전전류를 결정할 수 있다(S140).In consideration of the size of the memory of the portable battery 30, the information transmitted to the server 10 is deleted and later, if necessary, the charging station 20 is transmitted from the server 10 (S120) and received from the portable battery 30. The charging current of the portable battery 30 inserted into the accommodation unit may be determined by combining the information and the battery information received from the server 10 (S140).
휴대용 배터리(30)의 충전전류가 크면 빨리 충전할 수 있으나, 수명 측면에서는 바람직 하지 않다. 특히 노후화된 휴대용 배터리(30)의 경우 높은 전류로 충전하면 노후화가 더 빨리 진해된다. 즉, 충방전 횟수가 많고 충 방전시 높은 전류로 충전 및 방전된 휴대용 배터리(30)가 노후화 된 것으로 판단하고 충방전 횟수가 적을수록 새 배터리(30)로 판단한다. If the charging current of the portable battery 30 is large, it can be charged quickly, but it is not preferable in terms of lifespan. In particular, in the case of the aging portable battery 30, charging with a high current becomes faster aging. That is, it is determined that the number of charge / discharge cycles is high and the portable battery 30 charged and discharged with a high current during charge and discharge is deteriorated, and as the number of charge / discharge cycles is small, the new battery 30 is determined.
기본적으로 일반 충전을 하나, 충전 스테이션(20)에 보유하고 있는 완충된 휴대용 배터리(30)의 개수가 많은 경우 또는 노후화된 휴대용 배터리(30)인 경우 저속충전을 할 수 있다. 배터리(30)의 상태가 좋고 충전 스테이션(20)에 보유하고 있는 완충된 휴대용 배터리(30)의 개수가 적은 경우 쾌속 충전을 할 수 있다. Basically, the general charging is performed. However, when the number of fully charged portable batteries 30 held in the charging station 20 is large, or when the portable batteries 30 are aged, low-speed charging may be performed. If the state of the battery 30 is good and the number of fully charged portable batteries 30 held in the charging station 20 is small, fast charging can be performed.
도 7은 본 발명의 휴대용 배터리 충전 시스템(1)의 예약 및 사용자 인증 메커니즘을 도식화한 도면이다. 충전 스테이션(20)은 배터리 정보 이외에 스테이션(20)의 상태에 관한 스테이션(20) 정보도 서버(10)로 전송할 수 있다. 스테이션(20) 정보는 수용부에 수납된 휴대용 배터리(30)의 개수 및 충전량 등에 대한 정보를 포함할 수 있다. 이렇게 수집된 스테이션(20) 정보를 서버(10)는 사용자 단말기(50)로 제공할 수 있다(S210). 사용자 단말기(50)는 스테이션(20) 정보를 통해 휴대용 배터리(30)를 교환할 수 있는 충전 스테이션(20)을 검색할 수 있다. 또는 서버(10)에서 사용자가 요청한 배터리(30) 교환 시간 및 배터리(30) 개수의 완충 배터리(30)를 보유한 충전 스테이션(20)을 선정하여 대한 정보를 제공할 수 있다. 7 is a diagram illustrating a reservation and user authentication mechanism of the portable battery charging system 1 of the present invention. In addition to the battery information, the charging station 20 may also transmit station 20 information regarding the state of the station 20 to the server 10. The station 20 information may include information about the number and charge amount of the portable battery 30 stored in the accommodation unit. The server 10 may provide the collected station 20 information to the user terminal 50 (S210). The user terminal 50 may search for the charging station 20 that can exchange the portable battery 30 through the station 20 information. Alternatively, the server 10 may provide information on the charging station 20 having the battery 30 exchange time and the number of the battery 30 buffer batteries 30 requested by the user.
사용자 단말기(50)에서 서버(10)로 예약이 요청되면(S220), 서버(10)는 해당 충전 스테이션(20)에 예약 정보를 전송한다(S230). 도 6에 도시된 바와 같이 배터리(30) 예약을 전송받으면 충전 스테이션(20)은 기존의 충전 스케줄을 변경하여 배터리(30)별 맞춤 충전을 한다. 예약이 요청이 있으나 완충된 배터리(30)가 부족한 경우에는 기존의 충전 규칙에 대한 예외로 완충에 가까운 배터리(30) 중 배터리(30) 상태가 좋은 배터리(30)의 충전 전류를 높여 완충상태에 빨리 도달하도록 예외처리를 할 수 있다. If a reservation is requested from the user terminal 50 to the server 10 (S220), the server 10 transmits the reservation information to the corresponding charging station 20 (S230). As shown in FIG. 6, when the reservation of the battery 30 is received, the charging station 20 changes the existing charging schedule to perform custom charging for each battery 30. If the reservation is requested but the fully charged battery 30 is insufficient, the charging current of the battery 30 that is in a good state of the battery 30 among the close to fully charged battery 30 is increased to a fully charged state as an exception to the existing charging rule. You can do exception handling to get to it quickly.
