Abstract
A battery module includes cells positioned in cell holders and a casing. A cell support structure is integrated with a first inner surface of the casing for establishing a thermal contact between the cells and the first inner surface. Further, the battery module includes a flexible member positioned between a second inner surface of the casing and one of the cell holders for exerting pressure on the cell holders. A thermal interface member is in contact with at least one of the cell holders. The flexible member, the thermal interface member, and the cell support structure package the cells efficiently, making the battery module mechanically stable, impact resistant, and vibration proof.
Claims19
A battery module of a powered device comprising:
- a plurality of cells positioned in one or more cell holders;
- a casing enclosing the plurality of cells positioned in the one or more cell holders, wherein the casing comprises a first inner surface;
- and
- a cell support structure integrated with the first inner surface of the casing for establishing a thermally conducting and electrically insulating contact between the plurality of cells and the first inner surface.
A method of assembly of a battery module comprising the steps of:
- obtaining a casing and a plurality of cells enclosed in one or more cell holders,
- wherein the casing comprises a first inner surface and a second inner surface, and
- wherein a cell support structure integrated with the first inner surface of the casing;
- positioning the one or more cell holders in the casing, wherein the plurality of cells in the one or more cell holders is in thermally conducting and electrically insulating contact with the cell support structure;
- and
- sliding a flexible member between the second inner surface of the casing and one of the one or more cell holders for exerting a pre-load pressure on the one or more cell holders to establish the thermally conducting and electrically insulating contact between the plurality of cells and the cell support structure to obtain the battery module.
