Connection coupling for the provision of electrical energy, storage system and motor vehicle with connection coupling

Abstract

The invention relates to a connection coupling (1) for an electrically conductive connection of a storage module (61) for electrical energy in a motor vehicle (50) to an electrical consumer system (51) of the motor vehicle (50) for providing electrical energy, with a first connection coupling half ( 2) and with a second connection coupling half (4), the first connection coupling half (2) being a plug (2a) and the second connection coupling half (4) being a socket (4a) for receiving the plug (2a), wherein the plug (2a) and the socket (4a) is designed to establish an electrically conductive connection to one another, and the socket (4a) has a plurality of movable contact elements (8) on its inner lateral surface (6) for the frictional contacting of the plug (2a). The invention further relates to a storage system (60) with a connection coupling (1) and at least one storage module (61) for electrical energy, and to a motor vehicle (50) with a storage system (60).

Description

technical field [0001] The invention relates to a coupling coupling for electrically conductive connection of storage modules for electrical energy in a motor vehicle. Furthermore, the invention relates to a storage system with a storage module for electrical energy comprising a plurality of storage cells (Speicherzellen, sometimes called storage cells), as well as to a storage system with a storage module for electrical energy and an electrical load system (elektrischen Verbrauchersystem, sometimes called electrical consumer system). Background technique [0002] A number of implementation possibilities are known for the electrical contacting of the storage module to the load system of the motor vehicle. The load system of the motor vehicle is usually connected to the storage module by means of a screw connection and thus provides conductivity. The screw connection can be screwed with a predetermined torque and thus reproducibly produces a similarly maintained electrical ...

Problems solved by technology

However, it is common for known plug-in connections to have a higher electrical contact resistance (Durchgangswiderstand, sometimes referred to as through resistance) than screw connections and thus cause higher current heat losses

The contacts of the known plug-in connections do not make sufficient contact with each other in order to enable contact resistance values ​​similar to screw connections
