일반적으로 전기자동차는 외부로부터 전원을 공급받아 이를 축적한 후 축전된 전류를 방전하여 전동기 및 전장품에 전력을 공급하도록되어 있다.In general, electric vehicles receive power from the outside, accumulate it, and discharge electric current stored therein to supply electric power to electric motors and electrical equipment.
즉, 도 1에 도시된 바와 같이, 종래 전기자동차는 배터리 충전장치를 구비하여 필요로 하는 전원을 외부로부터 공급받아 배터리에 충전하였다.That is, as shown in Figure 1, the conventional electric vehicle is provided with a battery charging device to receive the power required from the outside to charge the battery.

A control unit was needed to control the switch. That is, the conventional battery charging device requires a control unit for controlling the inductor and the main switch, thereby limiting the manufacturing cost.

이하, 본 고안에 따른 하나의 바람직한 실시 예를 첨부된 도면을 참조하여 상세히 설명하고자 한다.Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안에 따른 배터리의 충전장치를 도시한 것으로, 그 구성은 전원부(AC)에서 공급되는 전원을 정류하기위한 정류부(5), 정류된 전원을 높은 전원으로 변환하기 위한 인덕터(6), 인덕터(6)로부터 변환된 전원이 배터리(2)로 공급되는 것을 제어하기 위한 메인스위치(4), 그리고 배터리(2)로 공급되는 충전전압을 체크하기 위한 션트저항(3), 그리고 션트저항(3)으로부터 감지한 배터리(2)의 충전전압에 따라 메인스위치(4)를 제어하여 배터리(2)로의 충전전류를 차단하기 위한 씨피유(1)가 마련된다.Figure 1 shows a charging device for a battery according to the present invention, the configuration of the rectifier 5 for rectifying the power supplied from the power supply unit (AC), the inductor 6 for converting the rectified power to a high power supply (6) A main switch 4 for controlling the power supplied from the inductor 6 to the battery 2, a shunt resistor 3 for checking the charging voltage supplied to the battery 2, and a shunt resistor. In order to control the main switch 4 according to the charging voltage of the battery 2 detected from (3), the CFI 1 is provided to cut off the charging current to the battery 2.
전술한 구성부중 인덕터(6)는 전기자동차의 동력을 발생시키는 전동기의 3상중 어느 한상을 이용한 것으로, 철심에 권선된 코일에 전류를 흘렸을 때 코일에 발생하는 자력선과 쇄교하는 자속변화에 의해 전압이 발생되는 것을 이용한 것이다. 따라서, 종래 인덕터를 양호하게 대신할 수 있게된다.The inductor 6 of the above-described components uses any one of three phases of an electric motor that generates electric power of an electric vehicle, and when a current flows through a coil wound on an iron core, the inductor 6 generates a voltage by changing a magnetic flux that is connected to a magnetic force line generated in the coil. This is what is used. Therefore, it is possible to satisfactorily replace the conventional inductor.
그리고 메인스위치(4)를 제어하기 위한 씨피유(1)는 전체적인 자동차의 전원공급장치를 제어하기 위한 것으로, 이는 여분의 제어회로를 구비하고 있으므로, 종래 인턱터를 제어하기 위한 제어부를 대신할 수 있게된다.And the C oil (1) for controlling the main switch (4) is to control the power supply of the entire vehicle, which is provided with an extra control circuit, it is possible to replace the control unit for controlling the conventional inductor .
이하 전술한 구성부를 참조하여 본 고안에 따른 배터리의 충전장치의 동작을 설명하고자 한다.Hereinafter will be described the operation of the battery charging apparatus according to the present invention with reference to the above-described configuration.
전기자동차는 배터리(2)의 충전전압을 수시 측정하여 운전자에게 배터리(2)의 충전상태를 알리게된다. 따라서, 운전자는 배터리(2)의 충전상태에 따라 배터리(2)의 충전장치를 제어하여 부족분을 외부로부터 충전받게 한다.The electric vehicle measures the charging voltage of the battery 2 at any time to inform the driver of the charging state of the battery 2. Therefore, the driver controls the charging device of the battery 2 according to the state of charge of the battery 2 so that the shortage is charged from the outside.
즉, 션트저항(3)에 의하여 측정된 배터리(2)의 충전전압이 기준값 이하로 검출되면 운전자는 배터리(2)를 충전시키게 된다. 외부의 전원부(AC)로부터 공급되는 전원은 평활회로 등으로 구성된 정류부(5)를 통하여 정류된 다음 모터의 3상중 어느 한상으로 마련된 인덕터(6)에 의하여 배터리(2)를 충전할 수 있는 높은 전압으로 변환된다. 이 변환된 전류는 메인 스위치(4)의 스위칭동작을 통하여 배터리(2)로 공급되어 충전되게 되는데, 메인 스위치는 FET, 또는 IGBT 등으로 구현된다.That is, when the charging voltage of the battery 2 measured by the shunt resistor 3 is detected below the reference value, the driver charges the battery 2. The power supplied from the external power source AC is rectified through the rectifier 5 composed of a smoothing circuit and the like, and then a high voltage capable of charging the battery 2 by the inductor 6 provided as one of three phases of the motor. Is converted to. The converted current is supplied to the battery 2 through the switching operation of the main switch 4 to be charged. The main switch is implemented by FET, IGBT, or the like.
메인 스위치(4)를 통하여 배터리(2)로 공급된 충전전류는 배터리(2)의 충전전압을 감지하기 위한 션트저항(3)에 의하여 제어되는데, 이는 션트저항(3)에서 배터리(2)의 충전전압이 설정값 이상으로 검출되게 되면 씨피유(1)는 메인스위치(4)의 스위칭동작을 제어하여 배터리(2)로의 전원공급을 제어하게 된다.The charging current supplied to the battery 2 through the main switch 4 is controlled by a shunt resistor 3 for sensing the charging voltage of the battery 2, which is the shunt resistor 3 of the battery 2. When the charging voltage is detected to be greater than or equal to the set value, the CPI 1 controls the switching operation of the main switch 4 to control the power supply to the battery 2.
그리고 전술한 인덕터(6)는 배터리(3)의 충전시 동작되는 것으로, 이는 배터리(2)의 충전시 자동차의 운전은 정지되므로 자동차의 구동모터를 인덕터(6)로 사용할 수 있게 된다.In addition, the inductor 6 described above is operated at the time of charging the battery 3, and the driving of the vehicle is stopped when the battery 2 is charged, so that the driving motor of the vehicle can be used as the inductor 6.
이상에서 상세히 설명한 바와 같이, 본 고안에 따른 배터리의 충전장치는 인덕터를 간단히 구현할 수 있어, 제조단가를 낮출 수 있으며, 또한 종래 씨피유의 여분의 제어회로를 사용하므로서, 회로를 단순 설계할 수 있어 충전장치의 신뢰도를 향상시킬 수 있는 효과가 있다.As described in detail above, the battery charging device according to the present invention can easily implement the inductor, thereby lowering the manufacturing cost, and also by using an extra control circuit of the conventional CPI oil, the circuit can be simply designed and charged. There is an effect that can improve the reliability of the device.
