Battery

Abstract

A battery having a first direction and a second direction that are perpendicular to each other, characterized in that it comprises: a housing having a filling opening arranged on one side in the first direction; a battery cell located in the housing; an insulating plate arranged inside the housing on the side where the filling opening is located, wherein a flow opening associated with the filling opening is formed in the insulating plate and the first direction is perpendicular to the insulating plate;A deflector element arranged on the side of the insulating plate facing away from the filling opening and associated with the flow opening, the deflector element comprising a hollow connecting section and a deflector plate, one end of the connecting section being connected to the insulating plate, the other end of the connecting section being connected to the deflector plate, the projection of the filling opening in the first direction lying within the projection of the deflector plate in the first direction, the connecting section having a through opening, and the filling opening, the flow opening, and the opening forming a filling channel; wherein the projection area of ​​the deflector plate in the first direction is S1 in mm², the projection area of ​​the filling opening in the first direction is S2 in mm², and the distance between the deflector plate and the insulating plate is h in mm, where 0.01 ≤ (S2 / S1) * h ≤ 9.
