복수의 얼터네이터와 배터리를 구비한 전기자동차{Electric vehicle provided with plurality of alternators and batteries}Electric vehicle provided with multiple of alternators and batteries}

본 발명은 전기자동차에 관한 것으로, 보다 상세하게는 엔진과 연결된 하나 이상의 얼터네이터와 이 얼터네이터에 의해 발생한 전류를 저장하는 하나 이상의 배터리를 연결하여 각각 모듈화함으로써 동력계의 유지관리가 용이하게 이루어질 수 있도록 한 복수의 얼터네이터와 배터리를 구비한 전기자동차에 관한 것이다.The present invention relates to an electric vehicle, and more particularly, a plurality of alternators connected to an engine and one or more batteries for storing current generated by the alternators are connected to each other and modularized so that maintenance of the dynamometer can be easily performed. It relates to an electric vehicle having an alternator and a battery.

최근 들어 전기자동차는 다양한 변화를 모색하는 가운데, 골프카트로도 적용되고 있으며, 이에 따라 골프카트는 골프백만을 싣던 종전의 손수레 형태에서 모터의 구동력을 동력원으로 하여 골프백 뿐만 아니라 플레이어 등의 탑승자도 함께 실어 나를 수 있는 탈 것의 형태로 발전하고 있다.In recent years, electric vehicles have been applied to golf carts in search of various changes. Accordingly, golf carts are used to drive not only golf bags but also players such as players by driving power of motors in the form of carts. It is developing in the form of a vehicle that can be carried together.

그 한 예로서, 도 1에 개략적으로 도시된 전동 골프카트를 들 수 있는데, 이 골프카트는 도면부호 101로 도시된 바와 같이, 몸체를 이루는 외장부와 운행과 관련된 내장부로 구성되는 바, 외장부는 도시된 것처럼 차체(109), 구조프레임(112), 지붕판(115), 및 좌석(118) 등에 의해 이루어지는 한편, 내장부는 다시 전후방 차륜(110)과 스티어링 휠(116) 등으로 이루어지는 조향계와, 배터리(103), 구동모 터(105), 이 구동모터(105)의 동작을 제어하는 모터 제어부, 가솔린과 같은 화석연료를 연소하여 회전 구동력을 발생시키는 엔진(111), 및 이 엔진(111)의 회전 구동력을 이용해 전기를 발생시키는 제너레이터(113) 등으로 이루어진 동력계(120)로 구분된다.An example is an electric golf cart shown schematically in FIG. 1, which is composed of an exterior part constituting a body and an interior part associated with driving, as shown by reference numeral 101, the exterior part As shown, while the interior is made of a body 109, a structural frame 112, a roof plate 115, a seat 118, and the like, the interior portion is a steering system consisting of the front and rear wheels 110, steering wheel 116 and the like; , A battery 103, a driving motor 105, a motor controller for controlling the operation of the driving motor 105, an engine 111 for burning a fossil fuel such as gasoline to generate a rotational driving force, and the engine 111. It is divided into a dynamometer 120 consisting of a generator 113 for generating electricity using a rotational driving force of the).

여기에서, 배터리(103)는 충전 플러그 등을 통해 외부전원으로부터 공급되는 전기에너지를 저장하는 부분으로서, 좌석(118) 밑에 설치되며, 구동모터(105)는 후륜(110)의 구동축(114)에 연결되어 모터 제어부(107)를 통해 배터리(103)에서 공급되는 전류에 의해 후륜(110)을 고속 회전시킴으로써 카트(101)를 기동하도록 되어 있다.Here, the battery 103 is a portion for storing the electrical energy supplied from an external power source through a charging plug, etc., is installed under the seat 118, the drive motor 105 to the drive shaft 114 of the rear wheel 110. The cart 101 is started by rotating the rear wheel 110 at high speed by the current supplied from the battery 103 through the motor control unit 107.

한편, 종래의 전동 골프카트(101)는 동력계(120)에 엔진(111)과 제너레이터(113)를 구비하고 있어 자체 발전을 하도록 되어 있는 바, 도 2에 도시된 것처럼, 엔진(111)에서 연료를 연소하여 발생시킨 회전 구동력을 이용해 제너레이터(113)의 회전코일을 회전시킴으로써 회전코일로부터 정류자를 거쳐 직류전류를 얻게 되며, 발생된 전류는 충전기(104)를 거쳐 배터리(103)에 저장된다.
