Embodiment Construction
[0032] exist figure 1 A schematic longitudinal section through the terminal region of a battery module produced according to the method of the invention is shown in . The battery module terminal 1 shown here is surrounded by a sealing element 2 . The terminal 1 is electrically conductively connected to a battery cell 3 of the battery module. After encapsulation by overmolding, the battery cells 3 and the sealing element 2 of the battery module are surrounded by a common one-piece plastic sheath 4 and are insulated from the environment.
[0033] exist figure 2 shows how a plurality of battery cells 3 of a battery module produced according to the method of the invention are arranged after encapsulation. It can be seen here that all the battery cells 3 of the battery module are surrounded and fastened together by a common one-piece plastic sheath 4 . Only the battery module terminals 1 protrude from the plastic sheath 4 so that they are accessible from the outside.

The invention relates to a method for producing a battery module or battery system having a plurality of battery cells (3). The method comprises the steps of: providing a plurality of battery cells (3); interconnecting and, if necessary, arranging said battery cells by means of cell connectors into a battery module structure or a battery system structure; providing a battery module-terminal or battery system-terminal (1); and encapsulating all battery cells (3) of the battery module or battery system in a common plastic sheath (4) by overmolding such that the battery module Or battery cells (3) and cell connections of a battery system are substantially completely surrounded by a plastic sheath (4), wherein the battery module-terminal or battery system-terminal (1) remains accessible from the outside. The invention also relates to a battery module or battery system which can be produced according to the method according to the invention.
Description
technical field [0001] The invention relates to a method for producing a battery module or a battery system having a plurality of battery cells, and to a battery module or battery system produced according to this method. Background technique [0002] A battery module or battery system includes a rechargeable electrical energy accumulator that finds widespread use in portable consumer electronics and other applications, such as in partially or fully electrically driven motor vehicles. In automotive applications, battery modules and battery systems and especially lithium-ion battery modules or battery systems are considered as key technologies for the electrification of vehicle drive systems. For this reason, battery modules and battery systems with high capacity, preferably not less than 2 or 3 Ah, are required. For this purpose, such high-capacity battery modules and battery systems, and in particular lithium-ion battery modules and battery systems, are designed in a modul...
