Abstract

A pack and/or module based on elementary cells of a cylindrical design, in which the elementary cells are electrically connected to one another in series and parallel circuits by a cell contacting system, wherein a contacting of both poles of each elementary cell is provided on a free upper side of the module or pack, and to a battery system constructed therefrom, which is provided as a device for outputting and storing electrical energy. In order to produce a module and/or a pack that can be used to achieve customer-specific solutions, a carrier is spatially predefined as a module or pack format with a fixed number of elementary cells, wherein the electrical properties of the module and/or pack can be adjusted by selecting a cell contacting system with a respectively adapted interconnection of the elementary cells and these are connected on the free upper side of the module or pack.

First claim

1 . A module and/or pack comprising:
a plurality of elementary cells of a cylindrical design, wherein the elementary cells are electrically connected to one another in series and parallel circuits by a cell contacting system, and wherein a contacting of both positive and negative poles of each of the plurality of elementary cells is provided on a free upper side of the module or pack, and a carrier that is spatially predefined as a module or pack format with a fixed number of the plurality of elementary cells, wherein the electrical properties of the module and/or pack are adjusted by selecting the cell contacting system with a respectively adapted interconnection of the fixed number of the plurality of elementary cells and the fixed number of the plurality of elementary cells are connected on the free upper side of the module or pack.

2 . The module and/or pack according to claim 1 , wherein the cell contacting system is a closure of the free upper side of the pack and/or module.

3 . The module and/or pack according to claim 1 , wherein the carrier of the pack and/or module is a tray.

4 . The module and/or pack according to claim 1 , wherein the fixed number of the plurality of elementary cells are positioned upright and oriented in the same direction in the carrier.

5 . The module and/or pack according to claim 1 , wherein the cell contacting system comprises a plastic carrier, which is uniform for all variants of the pack and/or module, and a grid-like stamped and bent structure, which is adapted to a respective specification of the electrical properties and has insulations for an interconnection of the fixed number of the plurality of elementary cells in the form of a specific series and parallel interconnection which has two poles.

6 . The module and/or pack according to claim 5 , wherein the stamped and bent structure in the cell contacting system has a secure and electrically conductive contact with terminal strips, which end at the two poles.

7 . The module and/or pack according to claim 5 , wherein at least one of the group consisting of: detachable spring contacts, resistance-welded welding tabs, metal strips, and bonded connections are provided in a region of the stamped and bent structure for a secure electrical contact between the fixed number of the plurality of elementary cells and the cell contacting system.

8 . The module and/or pack according to claim 5 , wherein metallic components of the cell contacting system are anchored to and in the plastic carrier by catch mechanisms and/or adhesive bonding.

9 . The module and/or pack according to claim 1 , wherein a number of the plurality of cells in the carrier of a module or pack is an integer multiple of 2.

10 . A battery system, which is provided as a device for outputting and storing electrical energy,
wherein the battery system comprises a plurality of the packs and/or modules according to claim 1 , which are electrically connected or interconnected in a series and/or parallel configuration.
