Description
본 발명은 충전배터리의 충전에 관한 것으로, 특히 충전배터리가 완전 방전되어 충전이 안될 경우 충전배터리의 셀을 자극하여 충전배터리가 충전되도록 회복시키는 충전배터리의 과방전 시 충전배터리 충전회복장치에 관한 것이다.The present invention relates to the charging of a rechargeable battery, and more particularly, to a rechargeable battery charge recovery apparatus during overdischarge of a rechargeable battery that stimulates a cell of the rechargeable battery to recover the charged battery when the rechargeable battery is completely discharged and cannot be charged. .
도1은 종래의 충전회로도로이다.1 is a conventional charging circuit diagram.
도1을 참조하여 충전회로의 동작을 설명하면, 참조된 번호 100은 충전부이고 40은 충전배터리이다. 충전부(100)는 충전 전원부(10)와, 정전원회로(20)로 그리고 충전연결부(40, 41)로 구성된다. 충전전원부(10)는 정전원회로(20)로 일정 전원을 공급한다. 정전원회로(20)는 상기 전원을 공급받아 일정한 충전전류를 발생하여 충전배터리(40)로 출력하여 충전배터리(40)를 충전한다.Referring to Figure 1, the operation of the charging circuit, reference numeral 100 is a charging unit and 40 is a charging battery. The charging unit 100 includes a charging power supply unit 10, an electrostatic source circuit 20, and a charging connection unit 40, 41. The charging power supply unit 10 supplies a predetermined power to the electrostatic power source circuit 20. The electrostatic power source circuit 20 receives the power to generate a constant charging current and outputs the charging battery 40 to charge the charging battery 40.
상기한 충전장치는 일반적으로 장치코드리스 텔리폰(Codeless Telephone)이나 충전장치를 사용하는 단말기 등에 사용되고 있다. 상기 충전배터리로는 Ni-Cd배터리나 Ni-H배터리를 주로 사용한다. 그러나 사용자가 충전배터리를 사용하지 않고 오랫동안 방치하면 충전배터리는 완전방전을 하여 충전배터리의 셀이 다운되는 현상이 발생한다.The above-mentioned charging device is generally used in a device cordless telephone or a terminal using a charging device. As the rechargeable battery, a Ni-Cd battery or a Ni-H battery is mainly used. However, if the user leaves the battery for a long time without using the rechargeable battery, the rechargeable battery is completely discharged, causing the cells of the rechargeable battery to go down.
상술한 바와 같이 충전배터리가 오랫동안 방치되어 완전 방전된 경우 충전회로의 충전전류로 장시간 충전을 해도 충전배터리는 충전되지 않는 문제점이 있다. 또한 완전 방전된 충전배터리는 충전지를 교환하거나 에프터 서비스를 받아야 함으로 경비와 시간을 이중으로 소비하는 문제점이 있다.As described above, when the rechargeable battery is left for a long time and completely discharged, there is a problem in that the rechargeable battery is not charged even if it is charged for a long time with the charging current of the charging circuit. In addition, a fully discharged rechargeable battery has a problem of consuming twice the cost and time to replace the rechargeable battery or to receive after-sales service.
따라서 본 발명의 목적은 충전회로로부터 배터리로 자극전류를 흘려 충전배터리의 셀에 자극을 주어 충전할 수 있도록 회복키는 충전배터리의 완전방전 시 충전배터리 충전회복장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a charge battery charge recovery device during full discharge of a charge battery that allows a stimulation current to flow from a charging circuit to a battery to stimulate and charge a cell of a charge battery.

이하 본 발명에 따른 바람직한 실시 예를 첨부한 도면을 참조하여 상세히 설명한다. 우선 각 도면의 구성요소들에 참조부호를 부가함에 있어서, 동일한 구성요소들에 한해서는 비록 다른 도면상에 표시되더라도 가능한 한 동일한 부호를 가지도록 하고 있음에 유의해야 한다. 그리고 본 발명을 설명함에 있어서, 관련된 공지 기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우 그 상세한 설명을 생략한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.
도2는 본 발명의 실시 예에 따른 충전배터리 완전방전 시 충전배터리 회복장치의 회로도이다.2 is a circuit diagram of a rechargeable battery recovery apparatus during full discharge of a rechargeable battery according to an exemplary embodiment of the present invention.
이하 도2를 참조하여 설명하면, 충전장치는 충전부(100)와 충전배터리(40)로 구성된다. 충전부(100)는 충전 전원부(10)와 정전원회로(20)와, 자극전류발생부(50)와, 두 개의 충전컨넥터(40, 41)로 이루어진다. 충전 전원부(10)는 정전원회로(20)로 일정 전원을 공급한다. 정전원회로(20)는 상기 전원을 공급받아 일정한 충전전류를 발생하여 출력한다. 자극전류발생부(50)는 상기 충전전원을 입력받아 자극전류를 발생하여 출력한다. 충전컨넥터(40)는 충전배터리(40)의 양극단자에 연결되고, 충전컨넥터(41)는 충전배터리의 음극단자에 연결된다. 평상시에는 충전배터리(40)는 상기 정전원회로(20)로부터 일정한 정전류를 입력받아 충전배터리를 충전한다. 그러나 충전배터리(40)가 완전 방전되어 충전배터리의 셀이 다운(Down)된 경우에는 스위칭부(50)의 내부에 포함된 스위치를 온(On)하여 일정 시정수 동안 자극전류를 출력한다. 상기 자극전류발생부(50)로부터 출력된 자극전류는 충전컨넥터(40, 41)를 통해 충전배터리(40)의 셀을 자극하여 회복시킨다.Hereinafter, referring to FIG. 2, the charging device includes a charging unit 100 and a charging battery 40. The charging unit 100 includes a charging power supply unit 10, an electrostatic source circuit 20, a stimulation current generating unit 50, and two charging connectors 40 and 41. The charging power supply unit 10 supplies a predetermined power to the electrostatic power source circuit 20. The electrostatic source circuit 20 receives the power and generates and outputs a constant charging current. The stimulation current generating unit 50 receives the charging power and generates and outputs the stimulation current. The charging connector 40 is connected to the positive terminal of the charging battery 40, and the charging connector 41 is connected to the negative terminal of the charging battery. Usually, the charging battery 40 receives a constant constant current from the electrostatic power source circuit 20 to charge the charging battery. However, when the rechargeable battery 40 is completely discharged and the cell of the rechargeable battery is down, the switch included in the switching unit 50 is turned on to output a stimulus current for a predetermined time constant. The stimulation current output from the stimulation current generation unit 50 is restored by stimulating the cells of the charging battery 40 through the charging connectors 40 and 41.
도3은 도2의 자극전류발생부의 상세회로도이다.FIG. 3 is a detailed circuit diagram of the magnetic pole current generating unit of FIG. 2.
이하 도3을 참조하여 설명하면, 제1저항(R1)은 충전전원부(10)로부터 출력된 전류를 제한한다. 스위치(S/W)는 제1저항(R1)으로부터 출력된 제한전류를 온/오프한다. 상기 스위치가 온되면 미분기(52)는 상기 제1저항(R1)으로부터 출력된 제한전류를 입력받고, 커패시터와 제2저항에 의한 시정수를 가지는 펄스를 발생하여 출력한다. 다이오드(D)는 상기 미분기로부터 출력된 펄스를 일정전압으로 제한하여 출력한다. 트랜지스터(TR)는 상기 충전전원부로부터 전류를 컬렉터로 입력받고, 상기 다이오드로부터 제한된 제한펄스를 베이스로 입력받아 턴온되어 이미터로 자극전류를 출력한다.Referring to FIG. 3, the first resistor R1 limits the current output from the charging power supply unit 10. The switch S / W turns on / off the limit current output from the first resistor R1. When the switch is turned on, the differentiator 52 receives the limited current output from the first resistor R1 and generates and outputs a pulse having a time constant by the capacitor and the second resistor. The diode D outputs the pulse output from the differentiator by limiting it to a constant voltage. The transistor TR receives a current from the charging power supply unit as a collector, receives a limited pulse from the diode as a base, and turns on to output a stimulus current to the emitter.
상기한 바와 같이 본 발명은 과전류를 흘려 완전 방전된 충전배터리를 회복시킴으로서 충전배터리를 교환하고, 에프터 서비스를 받을 필요 없이 사용자가 조치할 수 있음으로 경비와 시간을 절약할 수 있는 이점이 있다.As described above, the present invention has the advantage of saving money and time by exchanging the rechargeable battery by recovering the fully discharged rechargeable battery by flowing an overcurrent, and allowing the user to take action without the need for after-sales service.
