Problems solved by technology

However, when a short circuit occurs between the cooler and the discharger, not only the electrical connection is interrupted, but also the heat conduction, which can lead to catastrophic failure, in which case the customer proposes to conduct heat via a potential-free path cooling requirements

Embodiment Construction

[0044] In the following drawings, the same or similar reference numerals are used for the same or similar elements, and the description of these elements will not be repeated. In addition, the drawings, their description and claims include multiple features in combination. Here, it is clear to the professional and technical personnel that these features can also be established alone, or they can further form a combination not explicitly described here.

[0045] Fig. 1 is a perspective view of an electric energy storage unit 100 according to an embodiment of the present invention. The electric energy storage unit 100 includes a supporting device 110, which has a cooling plate 120 at the bottom, a bracket 130 on its side wall, and a sliding rail 140 in the upper region for connecting the brackets 130 on two sides. The pressure block 160 may be fixed on the sliding rail 140 by a bolt connection 150 (for example, on each side bracket 130). The pressing block 160 itself can be fixed...

Abstract

The electrical energy storage unit has a storage element including an electrical storage unit (300) i.e. cell, and a cooling element (310). A retaining device (110) retains the electrical storage unit. The retaining device has a screw joint (150), a pressure pad (160), a hook and a rail. The screw joint, pressure pad, hook and rail are designed for pressing the cooling element on the cooling plate such that a segment (345) of the cooling element thermally contacts a cooling plate (120). The segment is arranged at a distance from the surface of the electrical storage unit.

Description

Technical field [0001] The invention relates to an electric energy storage unit. Background technique [0002] Good cooling is indispensable for modern electric energy storage devices such as batteries in automobiles. Its function is to quickly dissipate the heat generated in the process of converting stored chemical energy into electrical energy, thereby avoiding storage. The energy device is damaged or destroyed. [0003] In traditional methods, there are known several solutions to solve similar problems. For example, the patent application DE 10 2008 028 400.9 discloses the connection of the cooling fin and the cooling plate of the battery in different embodiments. [0004] In addition, patent application DE 102007066944.4 discloses a cooling device for a flat battery, which has cooling fins forming a heat conduction path. One thing to mention is that there is a thermal contact between these heat sinks and the cooling plate; this thermal contact should be made by casting to ens...
