일반적으로 전기자동차는 200V~350V의 고전압을 갖는 배터리(battery)로부터 전원을 공급받아 모터를 구동시켜 엔진을 작동시키도록 되어 있다.In general, an electric vehicle receives power from a battery having a high voltage of 200 V to 350 V to drive a motor to operate an engine.
그런데 종래에는 메인배터리로부터 모터를 구동시키는 모터구동제어부 사이에는 스위치기능을 하는 컨택터(contactor)가 접속되고, 상기 컨택터에는 메인배터리로부터 전원을 공급받는 보조배터리가 시스템 작동스위치와 함께 접속구성되어 있어 상기 컨택터는 보조배터리로부터 인가되는 전원에 의해 코일부가 자장을 발생시켜 접속단자가 온(ON) 상태를 유지하므로서 모터에 전원을 공급하게 되어 있다.However, in the related art, a contactor serving as a switch is connected between a motor drive control unit for driving a motor from a main battery, and a secondary battery supplied with power from the main battery is connected with a system operation switch. The contactor is configured to supply power to the motor while the coil part generates a magnetic field by the power applied from the auxiliary battery, thereby maintaining the ON state of the connection terminal.
상기의 경우 장기주행시 또는 장기정차시에 보조배터리에 의해 전원이 컨택터의 코일부에 전원을 계속해서 공급하게 되므로 메인배터리의 전력이 많이 소비되는 문제점이 있었다.In the above case, since power is continuously supplied to the coil part of the contactor by the auxiliary battery during long-term driving or long-term stop, power of the main battery is consumed a lot.
본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 본 고안의 목적은 전기자동차가 장기정차할때에 보조배터리로부터 소비되는 전력을 감소시킬 수 있는 장치를 제공하는데 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide a device that can reduce the power consumed from the auxiliary battery when the electric vehicle is stopped for a long time.

이하 첨부된 도면을 참조하여 본 고안을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.
제1도을 참조하여 설명하면, 전기자동차에 장착되어 있는 메인배터리(10)는 200V~350V의 고전압을 발생시켜 엔진을 구동시키는 모터(20)를 동작시키는 모터구동제어부(30)에 전원을 공급하며, 상기 메인배터리(10)와 모터구동제어부(30) 사이에는 스위치역할을 하는 컨택터(50)가 접속되어져 메인배터릭(10)로부터 모터구동제어부(30)에 공급되는 전류를 제어하게 된다.Referring to FIG. 1, the main battery 10 installed in the electric vehicle supplies power to the motor drive control unit 30 that operates the motor 20 driving the engine by generating a high voltage of 200V to 350V. A contactor 50 serving as a switch is connected between the main battery 10 and the motor drive control unit 30 to control the current supplied from the main battery 10 to the motor drive control unit 30.
상기 컨택터(50)는 2단으로된 접속단자(52)와 상기 접속단자(52)를 개폐시키는 릴레이 역할을 하는 코일부(56)로 구성되어져 코일부(56)에 전원이 인가되면 접속단자(52)가 접속(close)되어 메인배터리(10)로부터 모터구동제어부(30)에 전원이 인가되고 코일부(56)에 전원이 인가되지 않으면 접속단자(52)가 오프(open)되어 메인배터리로부터 모터구동제어부(30)에 전류가 인가되지 않는다.The contactor 50 is composed of a connection terminal 52 having two stages and a coil unit 56 serving as a relay for opening and closing the connection terminal 52. When power is applied to the coil unit 56, the connection terminal When 52 is closed and power is supplied from the main battery 10 to the motor drive control unit 30 and no power is applied to the coil unit 56, the connection terminal 52 is opened to open the main battery. No current is applied to the motor drive control unit 30 from the side.
상기 코일부(56)에는 메인배터리(10)로부터 공급되는 전압을 낮은전압(약12V)으로 다운시킨 보조배터리(60)가 접속되어져 시동스위치(62)가 온(ON)됨과 동시에 코일부(56)에 전류를 공급하게 된다.The coil part 56 is connected to the auxiliary battery 60 which lowers the voltage supplied from the main battery 10 to a low voltage (about 12V) so that the start switch 62 is turned on and the coil part 56 is turned on. ) To supply current.
즉, 상기 보조배터리(60)는 항상 메인배터리(10)로부터 전원을 공급받아 컨택터(50)의 코일부(56)에 전원을 공급하는데, 상기 보조배터리(60)와 코일부(56) 사는다이리스터(70)가 접속되어 보조배터리(60)가 코일부(56)에 전원을 공급하는 것을 제어하게 된다.That is, the auxiliary battery 60 always receives power from the main battery 10 to supply power to the coil unit 56 of the contactor 50, and the auxiliary battery 60 and the coil unit 56 may buy power. The thyristor 70 is connected to control the auxiliary battery 60 to supply power to the coil unit 56.
상기 다이리스터(70)에는 타이머(80)가 접속되어 일정주기로 다이리스터(70)를 온(ON), 오프(Off) 동작시키게 된다.The timer 80 is connected to the thyristor 70 to turn on and off the thyristor 70 at a predetermined cycle.
따라서 상기 타이머(80)에서 발생되는 스위칭펄스(switching pulse)에 의해 다이리스터(70)가 온(ON), 오프(Off)되고, 상기 다이리스터(70)가 타이머(80)의 펄스 발생주기에 따라 온(ON), 오프(Off)되면 보조배터리(60)가 타이머(80)의 펄스 발생주기에 맞춰 코일부(56)에 전원을 공급하게 된다.Therefore, the die thruster 70 is turned on and off by a switching pulse generated by the timer 80, and the thyristor 70 is turned on in the pulse generation period of the timer 80. Accordingly, when ON and OFF, the auxiliary battery 60 supplies power to the coil unit 56 according to the pulse generation period of the timer 80.
상기와 같이 코일부(56)에 일정주기로 공급되는 전류의 주기는 코일부(56)에 전류가 인가 되었을때 발생되는 전자장이 발생되어 접속단자를 온(ON)시키게 되는데 상기 전자장은 전류가 오프(OFF)되면 일정시간동안 잔류 자장이 발생된다.As described above, in the period of the current supplied to the coil unit 56 at a predetermined cycle, an electromagnetic field generated when a current is applied to the coil unit 56 is generated to turn on the connection terminal. OFF), a residual magnetic field is generated for a certain time.
즉 잔류자장의 발생시간 동안 전원공급을 중단시키고 잔류자장이 사라지기 전에 다시 전원을 공급시키는 동작을 반복하므로서 전력소모를 최소화시키게 된다.That is, power consumption is minimized by stopping the power supply during the occurrence of residual magnetic field and repeating the operation of supplying power again before the residual magnetic field disappears.
이상설명에서 알 수 있는 바와 같이, 본 고안은 고전압을 발생시키는 메인배터리(main battery)와 모터사이에 접속되어 스위치기능을 하는 컨택터에 일정주기로 펄스신호를 발생시키는 타이머에 의해 제어되는 다이리스터를 접속시켜, 보조배터리가 컨택터를 작동시킬때 상기 다이리스터와 타이머에 의해 일정주기로 컨택터를 온(ON), 오프(OFF)시키므로서 메인배터리가 모터에 최소한의 전력만을 공급시키므로서 메인배터리의 전력소모를 최소화할 수 있게 된다.As can be seen from the above description, the present invention is connected between the main battery (generator) and the motor for generating a high voltage, the thyristor is controlled by a timer for generating a pulse signal at a predetermined period to the contactor functioning a switch function. When the auxiliary battery operates the contactor, the main battery turns on and off the contactor at regular intervals by the thyristors and the timer so that the main battery supplies the motor with the minimum power. The power consumption can be minimized.
