The present invention relates to a state of charge indicator for an electric vehicle capable of showing a state of charge of an electric vehicle by using the order of turn-on of a plurality of indicators or color variation of one indicator lens. The present invention provides the state of charge indicator that comprises: a light dispersion cap applied to the back surface of a lens to solve the non-uniformity due to point-light source characteristics of LED emission projected to a lens unit in accordance with the design restrictions (aspherical shape) so as to achieve the illuminance uniformity by scattering the light emitted from the LED inside the dispersion cap to be changed into a plane-light source when the light reaches the lens unit; and a thermal radiation heat-sink structure to radiate heat generated in the LED and a MICOM and guarantee electrical durability.

    본 발명은 전기자동차의 충전 상태를 다수의 인디케이터 렌즈의 점등 순서나 하나의 인디케이터 렌즈의 칼라 변화 등으로 나타내는 전기자동차의 충전 인디케이터에 관한 것이다. 본 발명은 디자인 형상 제약(비구면)에 따른 렌즈부에 투영되는 LED 조사 빛의 점 광원에 의한 불균일을 해소하기 위해 렌즈 배면에 빛 확산 캡을 적용함으로써, LED에서 조사된 빛이 확산캡 내부에서 난반사를 통해 렌즈부에 도달 시에는 면 발광 광원이 되도록 하여 조명 균일도 확보할 수 있는 한편, LED 및 마이콤에서 발생된 열을 방출하는 열 전도 방열구조를 적용함으로써, 전기적 성능 내구 안전성을 확보할 수 있는 전기자동차의 충전 인디케이터를 제공한다.
