Abstract
A housing for receiving a rechargeable battery pack having a plurality of rechargeable battery cells, in particular prismatic rechargeable battery cells or rechargeable pouch battery cells, having an encircling, preferably injection-molded, housing wall of plastics material which laterally surrounds a receptacle space for the rechargeable battery pack and in which at least one wound package wound from a strand of continuous fibers is integrated as a reinforcement structure, and to a method for producing such a housing.
Claims27
A housing for receiving a rechargeable battery pack (11) having a plurality of rechargeable battery cells, having an injection-molded encircling housing wall (12) of a plastics material and having a shape which laterally surrounds a receptacle space for the rechargeable battery pack (11), and in which at least one wound package (19) wound from a strand of continuous fibers is integrated in the encircling housing wall (12) as a reinforcement structure, wherein the wound package (19) integrated in the encircling housing wall (12) is a hollow member that at least in portions is adapted to the shape of the encircling housing wall (12), and wherein the wound package (19) has windings that run in the encircling housing wall (12).
An assembly of a housing and a rechargeable battery pack (11) contained therein, said rechargeable battery pack (11) having a group of rechargeable battery cells which are adjacent to one another and disposed beside one another in one row, and said housing having an injection-molded encircling housing wall (12) of a plastics material and having a shape which laterally surrounds a receptacle space for the rechargeable battery pack (11), and in which at least one wound package (19) wound from a strand of continuous fibers is integrated in the encircling housing wall (12) as a reinforcement structure, wherein the wound package (19) integrated in the encircling housing wall (12) is a hollow member that at least in portions is adapted to the shape of the encircling housing wall (12), and wherein the wound package (19) has windings that run in the encircling housing wall (12).
A method for producing a housing for receiving a rechargeable battery pack (11) having a plurality of rechargeable battery cells, the method comprising:
- a) winding a wound package (19) from a continuous fiber strand for producing an encircling housing wall (12) having a shape that laterally surrounds a receptacle space for a rechargeable battery pack (11), wherein the wound package (19) is formed as a hollow member which at least in portions is adapted to the shape of the encircling housing wall (12);
- and
- b) producing the encircling housing wall (12) that laterally surrounds the rechargeable battery pack (11) by over-molding or insert-molding, on all sides, the wound package (19) with plastics material in an injection-molding device, so that windings of the wound package (19) run in the encircling housing wall (19).
A method for producing an assembly of a housing for receiving a rechargeable battery pack (11), the rechargeable battery pack (11) having a plurality of rechargeable battery cells that are mutually adjacent to one another and are disposed beside one another in one row, the method comprising:
- a) producing, by winding from a continuous fiber strand, a wound package (19) for producing an encircling housing wall (12) has a shape that laterally surrounds a receptacle space for the rechargeable battery pack (11), wherein the wound package (19) is formed as a hollow member which at least in portions is adapted to the shape of the encircling housing wall (12);
- b) producing the encircling housing wall (12) which laterally surrounds the receptacle space for a rechargeable battery pack (11), by inserting the hollow wound package (19) into an injection-molding device, and subsequently over-molding or insert-molding, on all sides, the hollow wound package (19) with plastics material, so that windings of the wound package (19) run in the encircling housing wall (12);
- and
- c) incorporating the rechargeable battery pack (11) into the receptacle space.
