본 고안은 전기자동차에 장착되는 메인콘택터의 구동회로에 관한 것으로서, 특히 시동시에 주축전지가 보조축전지의 역할을 하도록 장치하여, 보조축전지의 용량을 적게 할 수 있도록 하는 전기자동차의 비상점프용 스위치에 관한 것이다.The present invention relates to a driving circuit of a main contactor mounted on an electric vehicle, and in particular, a switch for an emergency jump of an electric vehicle to reduce the capacity of the auxiliary battery by installing the main battery to serve as a secondary battery at start-up. It is about.
일반적으로, 전기자동차는 구동력을 발생시키는 전동기와 상기 전동기의 구동을 제어하는 제어장치가 장착되고, 상기 전동기에 고압전원(통상120V이상)의 주축전지가 통전 가능하게 연결되어 전원을 공급하며, 저압전원(통상12V)의 보조축전지가 상기 제어장치와 메인콘택터(main contactor)에 연결되어 상기 전동기의 구동을 위한 초기상태를 기동하도록 되어 있다.In general, an electric vehicle is equipped with a motor for generating a driving force and a control device for controlling the driving of the motor, the main battery of the high-voltage power supply (normally 120V or more) is electrically connected to the electric motor to supply power, low pressure A secondary battery of a power supply (usually 12V) is connected to the control device and the main contactor to start an initial state for driving the motor.
한편, 제1도는 12V전원의 보조축전지(10)에 메인콘택터(20)가 연결된 상태를 나타내는 개략적인 회로도로서, 보조축전지(10)와 메인콘택터(20) 사이에 기동스위치(30)가 전원을 단속할 수 있도록 연결되어 있다.1 is a schematic circuit diagram illustrating a state in which a main contactor 20 is connected to an auxiliary battery 10 of a 12V power supply, and a start switch 30 supplies power between the auxiliary battery 10 and the main contactor 20. It is connected to control.
이와같이 구성되는 종래 전기자동차는, 기동스위치(30)를 ON시키면 보조축전지(10)의 12V전원이 메인콘택터(20)에 인가되어, 메인콘택터(20)가 전기적으로 접속되고, 메인콘택터(20)의 접속에 의해 전동기를 구동할 수 있는 각 제어회로 등이 통전되게 된다.In the conventional electric vehicle configured as described above, when the start switch 30 is turned on, the 12 V power supply of the auxiliary storage battery 10 is applied to the main contactor 20, and the main contactor 20 is electrically connected to the main contactor 20. Each control circuit and the like that can drive the electric motor are energized by the connection of.
그러나, 이러한 종래 전기자동차는 차량의 중량을 줄이기 위해 보조축전지의 용량도 작게 만드는 것이 통례인데, 이로인해, 보조축전지(10)가 완전방전되는 경우가 종종 발생되며, 보조축전지(10)의 완전방전시 기동스위치(30)를 ON시켜도 12V전원이 필요한 메인콘택터(20)나 릴레이 등이 기동되지 않아, 자동차가 주행할 수 있도록 전동기의 구동이 불가능하게 되는 문제점이 있었다.However, in the conventional electric vehicle, it is common to make the capacity of the auxiliary battery small in order to reduce the weight of the vehicle. As a result, a case where the auxiliary battery 10 is completely discharged often occurs, and the full discharge of the auxiliary battery 10 is caused. Even when the start switch 30 is turned on, the main contactor 20 or the relay, which requires the 12V power supply, does not start, and there is a problem that the motor cannot be driven so that the vehicle can run.
본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위해, 주축전지의 한셀과 보조축전지의 단자를 병열로 연결하고, 상기 주축전지의 전원을 개폐하는 비상스위치를 장치하여, 시동시 주축전지의 한셀이 보조축전지의 역할을 대신하도록 하는 전기자동차의 비상 점프용 스위치를 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, by connecting a terminal of the main battery and the terminal of the secondary battery in parallel, and equipped with an emergency switch for opening and closing the power of the main battery, It is to provide an emergency jump switch for an electric vehicle, in which a cell replaces a secondary battery.
이하 첨부된 도면에 의해 본 고안의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention with reference to the accompanying drawings in detail.
본 고안도 제2도에 도시되는 바와 같이, 12V전원의 보조축전지(10)에 메인콘택터(20)가 통전 가능하게 연결되고, 보조축전지(10)와 메인콘택터(20) 사이에 기동스위치(30)가 전원을 단속할 수 있도록 연결되는 것은 종래와 같다. 단, 본 고안은 보조축전지(10)의 전압과 일치하는 주축전지(40)의 한셀(a cell)과 보조축전지(10)의 단자를 병열로 연결하고, 주축전지(40)에 연결되는 전원을 단속할 수 있도록 하는 별도의 비상스위치(50)를 운전석에서 조작할 수 있도록 장치하여, 시동시 주축전지(40)의 한셀이 보조축전지(10)의 역할을 대신하도록 함을 그 기술적 구성상의 기본 특징으로 한다.As shown in FIG. 2 of the present invention, the main contactor 20 is electrically connected to the auxiliary storage battery 10 of the 12V power supply, and the start switch 30 is connected between the auxiliary storage battery 10 and the main contactor 20. ) Is connected so as to interrupt the power supply as in the prior art. However, the present invention connects one cell (a cell) of the main battery 40 and the terminals of the auxiliary battery 10 in parallel to match the voltage of the auxiliary battery 10, and connects a power source connected to the main battery 40. It is designed to operate a separate emergency switch 50 to control the driver from the driver's seat, so that one cell of the main battery 40 replaces the role of the auxiliary battery 10 at the start-up. It is done.
한편, 비상스위치(50)는 리턴스프링(51)에 탄지되어, 누르는 동안만 통전되도록 함이 바람직하다.On the other hand, the emergency switch 50 is preferably touched by the return spring 51, so that it is energized only during the pressing.
이와같이 구성되는 본 고안은 보조축전지(10)가 완전히 방전되었을 때 시동시 비상스위치(50)를 누르면, 주축전지(40)의 한쪽 셀에서 보조축전지(10)와 같은 전원인 12V가 기동스위치(30)를 통해 통전되어 메인콘택터(20)를 ON시켜 주며, 시동후 비상스위치(50)를 놓으면, 리턴스프링(51)의 복원력에 의해 주축전지(40)로부터의 전원이 단전되고, 기동스위치(30)의 조작에 따라 메인콘택터(20)가 작동된다.According to the present invention configured as described above, when the auxiliary battery 10 is completely discharged, when the emergency switch 50 is pressed at the start, 12V, which is the same power source as the auxiliary battery 10 in one cell of the main battery 40, is activated. The main contactor 20 is turned on and the emergency switch 50 is released after starting, and the power from the main battery 40 is disconnected by the restoring force of the return spring 51, and the start switch 30 The main contactor 20 is operated according to the operation of.
따라서, 이러한 본 고안은 완전히 방전되기까지 걸리는 시간이 보조축전지(10)에 비해 비교적 긴 주축전지(40)에 의해, 보조축전지(10)의 역할을 수행할 수 있게 되어, 비교적 적은 용량의 보조축전지(10) 사용이 가능하도록 하며, 이로인해, 차량의 전체 중량을 줄여 줄 수 있도록 한다.Therefore, the present invention is able to perform the role of the auxiliary storage battery 10 by the main battery 40, which takes a long time to completely discharge compared to the auxiliary storage battery 10, the secondary storage battery of a relatively small capacity (10) to be available, thereby reducing the overall weight of the vehicle.
이상에서 살펴본 바와 같이, 본 고안은 주축전지의 한셀과 보조축전지의 단자가 병열로 연결되고, 상기 주축전지에 연결되는 전원을 단속하는 비상스위치가 장치되어, 시동시 주축전지의 한셀이 보조축전지의 역할을 대신하도록 하는 유용한 것이다.As described above, the subject innovation is that one cell of the main battery and the terminals of the auxiliary battery are connected in parallel, and an emergency switch is provided to control the power connected to the main battery. It is useful to take on a role.
