Description
본 발명은 모터 컨트롤러에 관한 것으로서, 보다 구체적으로는, 전기 자동차에 적용가능한 통합된 모터 컨트롤러에 관한 것이다. The present invention relates to a motor controller, and more particularly, to an integrated motor controller applicable to an electric vehicle.
최근에는 환경친화적인 기술의 구현에 많은 관심이 쏟아지고 있다. 이 중 하나가 석유원료 대신 전기로 구동되는 전기 자동차에 관한 것이다. 전기 자동차는 차량 내 구비되는 충전 가능한 배터리로부터 전기를 공급받아 동력을 출력하는 모터를 통해 작동된다. 따라서, 전기자동차는 이산화탄소의 배출이 없고 소음이 매우 작으며 에너지효율이 비교적 높다는 장점을 가지고 있다. Recently, much attention has been devoted to the implementation of environmentally friendly technologies. One of them relates to an electric vehicle driven by electricity instead of petroleum raw materials. The electric vehicle is operated through a motor that receives electricity from a rechargeable battery provided in the vehicle and outputs power. Therefore, the electric vehicle has an advantage that there is no emission of carbon dioxide, noise is very small, and energy efficiency is relatively high.
전기자동차에서 가장 중요한 부분은 배터리 및 모터이다. 배터리는 적정 온도 하에서 사용되어야 성능이 좋고, 긴 수명을 유지할 수 있다. 하지만 전기자동차에 구비되는 배터리는 자동차 구동 중에 발생하는 열이나 외부 환경에 의한 온도변화에 의해 최적 온도에서 사용되는 것이 어렵다. The most important parts of electric vehicles are batteries and motors. Batteries should be used under proper temperature to perform well and maintain long life. However, it is difficult for the battery provided in the electric vehicle to be used at an optimum temperature due to heat generated during driving of the vehicle or temperature change due to an external environment.
따라서, 전기 차량은 배터리의 열을 방열시키기 위해 펌프, 구동모터 등에 의해 동작되는 냉각시스템을 구비하고 있다. 또한, 모터, 인버터 등도 열 방출이 크므로 별도의 냉각시스템을 구비하고 있다. 이들 냉각시스템은 전체적으로 하나의 냉각선로를 따라 구성이 되는데 냉각시스템에는 펌프, 구동모터 등 여러 개의 모터를 구비하고 있어 이들을 하나의 제어기로부터 제어할 수 있는 시스템의 개발이 필요한 실정이다. Therefore, the electric vehicle is equipped with a cooling system operated by a pump, a driving motor, and the like to radiate heat from the battery. In addition, motors, inverters, and the like also have a large heat dissipation, and thus are equipped with separate cooling systems. These cooling systems are configured along one cooling line as a whole, and the cooling system is equipped with several motors such as pumps and drive motors, so it is necessary to develop a system that can control them from a single controller.
본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로서, The present invention has been devised to solve the above-mentioned problems,
전기자동차의 다수의 모터를 하나의 제어기로 제어할 수 있는 전기자동차용 통합 모터 컨트롤러를 제공하고자 한다. An object of the present invention is to provide an integrated motor controller for an electric vehicle that can control multiple motors of an electric vehicle with one controller.
