摘要:
The invention relates to an electrical energy accumulator (1), in particular for an electric vehicle, having a plurality of electrically interconnected, in particular flat and substantially plate-like, battery cells (4a, 4b) that are arranged one alongside another or one above another in at least one stack (3a, 3b), wherein the cell poles (6) of at least two electrically connected battery cells (4a, 4b) are connected to one another by at least one cell connector (8a, 8b, 8c, 8d), wherein at least one cell pole (6) and at least one cell connector (8a, 8b, 8c, 8d) are connected to one another, in particular by means of a clinching connection (7). To enable simple production of a compact energy accumulator (1), at least the cell pole (6) connected to the cell connector (8a, 8b, 8c, 8d) is bent over into a first plane (ε) perpendicular to the cell plane (4', 4") of the battery cells (4a, 4b).

The invention relates to an electrical energy store (1), in particular for motor vehicles, comprising at least one battery module (2) having a plurality of individual cells (4a, 4b) which are arranged in a stack (3) between two outer end plates (6), wherein preferably at least one individual cell (4a, 4b) is arranged in an individual module (5). In order to ensure a good conditioning of the battery module in a manner that is as simple and space-saving as possible, it is provided that a preferably flexible electrical heating element (9) is arranged between at least two individual cells (4a, 4b), preferably between two individual modules (5).

The invention relates to a rechargeable battery (100) which comprises at least one, preferably a plurality of battery cells (110, 110') that are arranged in frame elements (120, 120'), said frame elements (120, 120') having a main body which consists of a foamed material. Each frame element (120, 120') has a first transverse member (121, 121'), a second transverse member (122, 122') opposite the first transverse member (121, 121'), and two mutually opposed longitudinal members (123, 123'). The first transverse member (121) of a first frame element (120) can be arranged on a second transverse member (122') of an adjacent second frame element (120') in a substantially form-fit manner. The invention also relates to a corresponding method.
摘要:
The invention relates to an electrical energy store (1), in particular for an electric vehicle, which energy store has at least one battery module (2) having a plurality of, in particular flat and substantially plate-like, battery cells (4) which are electrically connected to one another and which are arranged next to one another or one above the other between at least two pressure plates (5) in at least one stack (3), and wherein at least one battery cell (4) and/or the battery module (2) is surrounded by a plastic structure (7), in particular encapsulated by foam. In order to allow the energy store to be fastened in a secure manner with as low a level of expenditure as possible and with a low number of parts, the invention proposes that the battery cells (4) are encapsulated by foam in the clamped state between the pressure plates (5).
