Title (EN) SAFETY SWITCH FOR SECONDARY BATTERY FOR ELECTRIC VEHICLE AND CHARGING/DISCHARGING SYSTEM FOR SECONDARY BATTERY FOR ELECTRIC VEHICLE USING THE SAME
(FR) INTERRUPTEUR DE SÉCURITÉ POUR BATTERIE DE SECOURS POUR VÉHICULE ÉLECTRIQUE ET SYSTÈME DE CHARGE/DÉCHARGE POUR BATTERIE DE SECOURS POUR VÉHICULE ÉLECTRIQUE UTILISANT UNE TELLE BATTERIE
(KO) 전기자동차용 2차 전지의 안전 스위치 및 이를 이용한 전기자동차용 2차 전지의 충방전 시스템
Abstract: front page image
(EN)The present invention relates to a safety switch for a secondary battery for an electric vehicle and a charging/discharging system for a secondary battery for an electric vehicle using the same, and more particularly, to a technique for protecting the secondary battery by operating the switch of the secondary battery for the electric vehicle attached to the outside of the secondary battery to cut the connection between the secondary battery and an electric vehicle driving motor in cases where the secondary battery swells or an excessive short-circuit current flows along the circuit of the secondary battery owing to the abnormal use of the secondary battery for the electric vehicle, for example, overcharge, exposure to heat, disconnection, reverse connection and the like.
(FR)La présente invention concerne un interrupteur de sécurité pour une batterie de secours pour un véhicule électrique et un système de charge/décharge pour une batterie de secours pour un véhicule électrique utilisant une telle batterie. Plus particulièrement, l'invention concerne un procédé permettant de protéger la batterie de secours par actionnement de l'interrupteur de la batterie de secours pour le véhicule électrique relié à l'extérieur de ladite batterie de secours afin de couper la connexion entre la batterie de secours et un moteur d'entraînement de véhicule électrique en cas de gonflement de la batterie ou si un courant de court-circuit excessif s'écoule le long du circuit de la batterie de secours en raison de l'utilisation anormale de la batterie de secours pour le véhicule électrique, par exemple, surcharge, exposition à la chaleur, déconnexion, connexion inversée, ou tout autre évènement analogue.
(KO)본 발명은 전기자동차용 2차 전지의 안전 스위치 및 이를 이용한 전기자동차용 2차 전지의 충방전 시스템에 관한 것으로서, 보다 상세하게는 전기자동차용 2차 전지의 사용에 있어서, 과 충전, 열 노출, 단락 및 역접속 등 2차 전지의 비정상적인 사용 상태로 인해 2차 전지가 팽창되는 스웰링(Swelling) 현상에 의해 상기 2차 전지가 팽창되거나 2차전지 회로에 과도한 단락전류가 흐를 경우 상기 2차 전지 외부에 부착된 전기자동차용 2차 전지의 스위치가 작동하여 상기 2차 전지와 전기자동차 구동모터의 연결을 차단하여 2차 전지를 보호하는 기술에 관한 것이다.
