The present disclosure relates to a relay device and a battery charging apparatus comprising same. A relay device according to an embodiment of the present disclosure comprises: a current limiter limiting a current of an input alternating current power source; a relay having a primary side connected between a first end and a second end which are both ends of the current limiter; a first power supply unit connected between a third end which is a secondary side of the relay and a ground end to supply first power; a first switching element connected between a fourth end which is a secondary side of the relay and the ground end; and a second power supply unit and a second switching element connected in series with each other between the fourth end and the ground end, wherein the second power supply unit supplies second power less than the first power. Accordingly, the heat generation of the relay may be reduced.

    La présente divulgation concerne un dispositif de relais et un appareil de charge de batterie le comprenant. Un dispositif de relais selon un mode de réalisation de la présente divulgation comprend : un limiteur de courant limitant un courant d'une source d'alimentation en courant alternatif d'entrée ; un relais comprenant un côté primaire connecté entre une première extrémité et une deuxième extrémité qui constituent les deux extrémités du limiteur de courant ; une première unité d'alimentation électrique connectée entre une troisième extrémité qui constitue un côté secondaire du relais et une extrémité de masse pour fournir une première puissance ; un premier élément de commutation connecté entre une quatrième extrémité qui constitue un côté secondaire du relais et l'extrémité de masse ; et une seconde unité d'alimentation électrique et un second élément de commutation connectés en série l'un à l'autre entre la quatrième extrémité et l'extrémité de masse, la seconde unité d'alimentation électrique fournissant une seconde puissance inférieure à la première puissance. Par conséquent, la génération de chaleur du relais peut être réduite.

    본 개시는 릴레이 장치, 및 이를 구비하는 배터리 충전 장치에 관한 것이다. 본 개시의 실시예에 따른 릴레이 장치는, 입력 교류 전원의 전류를 제한하는 전류 리미터와, 전류 리미터의 양단인 제1 단과 제2 단 사이에 1차측이 접속되는 릴레이와, 릴레이의 2차측인 제3 단과 접지단 사이에 접속되어 제1 전원을 공급하는 제1 전원 공급부와, 릴레이의 2차측인 제4 단과 접지단 사이에 접속되는 제1 스위칭 소자와, 제4 단과 접지단 사이에, 서로 직렬 접속되는 제2 전원 공급부와 제2 스위칭 소자를 포함하며, 제2 전원 공급부는, 제1 전원 보다 낮은 제2 전원을 공급한다. 이에 따라, 릴레이의 발열을 저감할 수 있게 된다.
