Through mount fixed type battery apparatus and electric vehicle thereof

Abstract

An electric vehicle includes a floor panel, a seat cross member positioned at the floor panel, the seat cross member including an upper bracket and a lower bracket that define an internal structure therebetween, and a battery apparatus. The battery apparatus includes a battery module disposed below the floor panel, and a through mount member that is coupled to a through mounting position of the battery module and passes through the internal structure of the seat cross member. The through mount member is coupled to the seat cross member by any one of CO2 welding-coupling, metal inert gas (MIG) welding-coupling, or an axial force coupling to thereby fix the battery module to the floor panel.
