전기차용 충전장치{charging equipment of an electric car}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

본 발명은 전기차용 충전장치에 관한 것으로서, 보다 상세하게는 여러 자동차회사에서 생산되고 있는 다양한 전기차에 선택적으로 사용할 수 있는 전기차용 충전장치를 제공함으로 해서 전기차 충전 인프라 구축이 용이하게 이루어질 수 있도록 한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charging device for an electric vehicle, and more particularly, to an electric vehicle charging device that can be selectively used in various electric vehicles manufactured by various automobile companies, .

전기차는 심각한 지구 온난화와 에너지자원 고갈 등의 문제를 해결할 수 있는 시대적 핵심 과제로, 미래 에너지자원 창출을 위한 창조경제의 실증사업에 우리의 강점인 자동차산업과 IT산업의 융합으로 선도하면, 세계시장에서 미래 자동차의 허브'를 구축할 수 있다하여 국가간 치열한 경쟁속에 독점적 선점기술을 확보치 못하면 살아남기 힘든 중요한 시점에서 전기차와 배터리의 개발에 비약적인 발전이 있음에도 불구하고 충전장치의 인프라 구축에 따른 어려움으로 전기차의 조기 대중화가 되지 못하고 있는 실정이다.Electric cars are a key task in the era that can solve serious global warming and depletion of energy resources and lead to demonstration of creative economy to create future energy resources. It is difficult to secure the proprietary pre-emptive technology within the fierce competition between the countries. However, despite the significant development in the development of the electric car and the battery at a critical point, The electric vehicles are not popularized in the early stage.

일반적으로 사용되고 있는 전기차용 충전장치의 경우 전기차 급속 충전방식은 직류를 사용하는 차데모와 콤보, 그리고 교류를 사용하는 3상 방식으로 대분되고 있으며, 현재까지는 국제 표준 규격이 이루어지지 않아 제조사별로 서로 다른 충전 방식을 사용하고 있는 실정이다.In the case of an electric car charging device which is generally used, the rapid charging method of an electric car is divided into a three-phase method using a car demo, a combo, and an alternating current using a direct current. Charging system.

차데모(CHAdeMO)는 일본 자동차 회사들이 추축으로 만든 규격으로 급속충전 직류(DC)전용과 완속충전 AC전용 따로 분리해 사용하는 커넥터가 구성되어 있으며, 콤보(COMBO)는 차데모와는 다르게 급속충전 직류(DC)와 완속충전 교류(AC)충전을 겸용으로 사용할 수 있도록 복합형 커넥터로 구성한 것을 현재 유럽 자동차 회사들이 표준화한 규격으로 제작 보급되고 있다.The car demo (CHAdeMO) is a standard made by Japanese automobile companies. It consists of a connector used separately for DC charging (DC charging) and DC charging (AC charging) separately. The combination of the DC (DC) and the continuous charge AC (AC) charging combined with the connector type is now becoming standardized and standardized by European automakers.

또한 교류를 사용하는 3상 방식은 현재 르노와 도요타 등의 기업에서 사용하고 있다.The three-phase approach using AC is currently used by companies such as Renault and Toyota.

상기에서 살펴본 바와 같은 다양한 구성의 충전 방식이 공존하고 있는 실정으로, 이들이 적용된 전기차 충전장치를 모두 충족하기 위해서는 개별적으로 충전장치를 시설해야 하므로 설치비용이 많이 들게 되는 문제점이 발생하게 되므로, 전기차의 충전장치 인프라 구축에 가장 큰 문제점으로 대두되고 있는 실정으로, 업계에서는 이와 같은 다양한 구성의 충전방식에 구애 없이 충전이 가능한 전기차용 충전장치가 요구되고 있는 실정이다.In order to satisfy all the electric vehicle charging devices to which the charging devices are applied, charging devices are required to be installed separately. Therefore, a problem arises that installation costs are increased, In the industry, the electric vehicle charging device which can charge the battery without charging regardless of the various charging schemes is required in the industry.
