Problems solved by technology

[0005] The inherent disadvantage of this liquid cooling is that the monolithic body requires an additional housing, which creates an additional structural space requirement
Furthermore, there is still no significant improvement in the achievable cooling performance relative to previously known cooling methods

Embodiment Construction

[0044] figure 1 A perspective view of a battery system according to the invention is shown, which is designated as a whole by the reference numeral 1 . The battery system 1 comprises a plurality of battery cells 2 which are electrically connected to one another. Each battery cell 2 includes a battery cell housing, which is designated with the reference numeral 2a. Furthermore, each battery cell 2 also has two electrical contacts or discharge bodies, which are designated by reference numerals 2b or 2c and each have a different electrical polarity (+ / -), which in this Also referred to as "first polarity" and "second polarity" within the scope of the application. In battery cells 2 arranged next to each other, discharge bodies 2 b , 2 c are arranged interchangeably with respect to their polarity, so that in adjacent battery cells 2 discharge bodies of different polarity are always directly adjacent to each other.

[0045] The battery system 1 has a contacting and temperature-r...

Abstract

The invention relates to a contact and temperature control device (3) for a battery system (1). The contact and temperature control device is provided with a fluid guiding system used for guiding temperature control fluid (F). The fluid guiding system is formed by a plurality of fluid guiding elements (3a, 3b, 3c,...) and is set to be used for contacting discharge bodies (2b, 2c) of the battery system (1). Thus, heat exchange is realized between the related discharge bodies (2b, 2c), the related fluid guiding element (3a) and the temperature adjusting fluid (F). Wherein the first number of fluid-conducting elements (3a, 3b) is made of an electrically conductive material, and the second number of fluid-conducting elements (3c) is made of an electrically non-conductive material, in order toachieve an electrical contact with the discharge body (2b, 2c) by means of the fluid-conducting system regardless of the temperature.

Description

technical field [0001] The invention relates to a contact and temperature control device for a battery system according to variant 1. [0002] Furthermore, the invention relates to a battery system according to claim 10 with a plurality of electrically connected battery cells, which has a contacting and temperature control device according to the invention. [0003] Finally, the invention relates to a method according to aspect 19 for electrically contacting an electrical system, wherein said electrical system is in particular a battery system or an electric machine. Background technique [0004] Electric traction or propulsion batteries are currently widely used in series in motor vehicles, such traction or propulsion batteries are generally not liquid-cooled but air-cooled. However, it is known that better electrical properties of the individual battery cells can be achieved by means of liquid cooling with regard to internal resistance, stable voltage and service life.
