Abstract

A battery module includes a plurality of secondary battery cells; one or more cooling tubes formed of a metal material; and a cooling plate formed of casted aluminum, the cooling plate being cast around the one or more cooling tubes, the one or more cooling tubes being molded within the cooling plate.

Claims

1. A battery module, comprising:

a plurality of secondary battery cells;

one or more cooling tubes formed of a metal material; and

a cooling plate formed of casted aluminum, the cooling plate being cast around the one or more cooling tubes, the one or more cooling tubes being molded within the cooling plate.

2. The battery module of claim 1, wherein the cooling plate is within a housing of the battery module.

3. The battery module of claim 2, wherein the secondary battery cells are arranged in two or more levels within the housing, each level including at least one cooling plate.

4. The battery module of claim 2, wherein a plurality of cooling interfaces connect the cooling tubes to supply lines or return lines, and

wherein the cooling interfaces are at an outer surface of the housing.

5. The battery module of claim 1, wherein two or more of the secondary battery cells are bundled in a row and at least two cooling tubes are positioned underneath the row such that each secondary battery cell is in thermal contact with the at least two cooling tubes.

6. The battery module of claim 1, wherein the metal material of the one or more cooling tubes is steel.

8. A vehicle including a battery module according to claim 1.

7. A method of manufacturing a cooling plate for a battery module comprising a plurality of secondary battery cells, the method comprising:

providing one or more preformed cooling tubes formed of a metal material in a casting die; and

casting aluminum into the casting die in order to form a cooling plate.
