A cell module for a battery of a motor vehicle has a plurality of battery cells for storing electrical energy and a module frame which includes at least two pressure elements, between which the battery cells are arranged, and at least one tension rod which is loaded in tension. The tension rod is formed from a material and by which the pressure elements are clamped against each other via the battery cells. As a result, the battery cells are compressed, wherein the pressure plates are clamped against each other by the tension rod in such a manner that a yield strength or the 0.2% yield limit of the material of the tension rod is reached.

A connector system for a battery module has a number of cell connectors of different successive cell connector types in order to form one or more electric contacts with one or more connections of one or more individual cells of the battery module, in particular for a power-transmitting tap in which each cell connector of a subsequent cell connector type is designed to electrically connect a larger number of connections of individual cells than the number of connections which can be connected by each cell connector of a preceding cell connector type. Each cell connector of a preceding cell connector type can be stacked and/or nested on a cell connector of a subsequent cell connector type in an assembly direction perpendicular to the main direction of extension.

A cell-contacting system for a motor-vehicle battery module, in particular for an electric or hybrid vehicle includes an, in particular, substantially plate-shaped support structure and multiple separate contact elements, each of which is used to contact two adjacent battery cells of the motor-vehicle battery module. The contact elements are arranged next to one another in a first row, each element being fixed at one side to the support structure.

An energy storage arrangement for supplying electric power, in particular in a motor vehicle, includes at least a first energy storage module and a second energy storage module mounted on top of the first energy storage module. Each energy storage module has two end plates and a plurality of storage cells tensioned between the end plates. At least one end plate of the first energy storage module is secured by at least one first screw, and at least one end plate of the second energy storage module is secured by at least one second screw. An internal thread is formed in the screw head of the first screw, and the second screw is screwed into the screw head of the first screw.
