A motor vehicle traction battery assembly has a battery control unit and battery modules. Each battery module includes a degassing opening. A plurality of busbars is arranged in a rail tunnel, to which the battery modules are electrically connected. The rail tunnel is fluidly shielded by a tunnel lid. The battery control unit includes an interior having a gas-tight battery control unit housing body in which connection rails and an electronic battery controller are accommodated. The electrical connections between the busbars and the connection rails are formed by vertical contact bodies, which pass through a connection opening lying in the horizontal plane between the rail tunnel and the battery control unit interior. The connection opening is fluidly sealed by a sealing wall, through which the contact bodies pass in a fluid-tight manner.
