Abstract: A contacting system for electrically interconnecting a plurality of energy storage cells of an electrical energy storage device, and an energy storage device such as, for example, a traction battery. The contacting system has cell pole connectors, formed for the electrical interconnection of in each case at least two cell poles of the energy storage cells respectively having at least two cell pole contact elements. At least one of the cell pole connectors has at least one board contact element, which is formed for the contacting of an electronic circuit and is connected in an electrically conducting manner to one of the cell pole contact elements of the cell pole connector by way of a contacting web. The contacting web has at least one web segment extending obliquely in relation to a cell pole contacting plane of the cell pole contact element.

Abstract: A high-current (HC) plug-in connector for currents exceeding 100 A, in particular 200 A, is provided. The high-current (HC) plug-in connector may include a first connecting element having a first contact section, and a second connecting element having a second contact section. Furthermore, a spring element is provided for establishing an electrical connection between the first and the second connecting element. The spring element may include at least two clamping elements which are interconnected via at least one web, the web and respective first sections of the clamping elements being arranged on a first outer surface of the connection formed by the first and the second contact section, and second sections of the clamping elements being arranged at least in part on a second outer surface opposite the first outer surface.
