Embodiment Construction

[0035] The invention is explained in more detail below with reference to the accompanying drawings, and first with reference to figure 1 .

[0036] figure 1 An electrical connection unit 120 is shown, which is adapted to electrically contact battery contacts (not shown in the figure). For this purpose, the electrical connection unit 120 has a first electrical terminal 104 which is formed as a screw connection in the illustrated embodiment. However, it is obvious to a person skilled in the art that other configurations of the first electrical terminal can also be used, such as a plug connector or a press-in connection.

[0037] The first electrical terminal 104 is part of a base body 122 that extends along a first longitudinal axis 124 . The base body 122 is partially hollow and has a first fluid terminal 108 for attaching a coolant line (not shown). In the illustrated embodiment, the first fluid terminal 108 is configured as a quick coupling. In this way, the electrical c...

Abstract

The present invention relates to an electrical connection unit with integrated cooling and a battery system, which has such a connection unit. In particular, the cooling can be achieved by means of aliquid coolant. An electrical connection unit (120) comprises a first electrical terminal (104) for contacting a first electrical component, a second electrical terminal (106) which is connected to anelectrically conductive cable (100), wherein the electrical connection unit (120) establishes an electrical connection between the first electrical terminal (104) and the second electrical terminal (106), and a first fluidic terminal (108) for attaching a coolant source. The second electrical terminal (106), moreover, is formed as a second fluidic terminal (110), such that it connects a cooling channel (103), which is arranged on the cable (100) and through which a coolant for cooling the electrically conductive cable can flow, to the first fluidic terminal (108).

Description

technical field [0001] The invention relates to an electrical connection unit with integrated cooling and to a battery system with such a connection unit. In particular, this cooling can be achieved by means of a liquid coolant. Background technique [0002] All electronic components, appliances and circuits generate excess heat and require thermal management to improve reliability and prevent premature failure. In particular, in the case of the electrical connection of battery systems in motor vehicles, high currents and thus large amounts of heat are generated at the electrical contacts of the battery, which must be dissipated as quickly and efficiently as possible in order to avoid dangerous overheat. [0003] Various techniques exist for cooling electrical components, such as air cooling using fans or thermoelectric cooling based on the Peltier effect. Conventional air cooling systems with fans are limited in their ability to dissipate heat. Therefore, they are only ...
