Embodiment Construction

[0045] Such as figure 2 shown, according to the present invention figure 2 The device 1 of the embodiment comprises a plurality of electric energy storage batteries 1 - 1 , 1 - 2 , wherein each of the electric energy storage batteries 1 - 1 , 1 - 2 has two electrode posts 2 , 3 . For example, the first electrical energy storage cell 1-1 comprises a first or positive electrode post 2-1, and a second or negative electrode post 3-1. Likewise, the second electric energy storage battery 1-2 has a first positive electrode column 2-2 and a negative electrode column 3-2. Such as figure 2 As shown, a contact assembly 4-1, 4-2 is arranged on the two positive electrode columns 2-1, 2-2 of the electric energy storage battery 1-1, 1-2. Similarly, if figure 2 As shown, a contact assembly 5-1, 5-2 is disposed on the two negative electrode posts 3-1, 3-2. The contact elements 4-1, 4-2, 5-1, 5-2 form connection elements comprising an elastic contact material that is electrically and t...

Abstract

The invention provides a device for contacting a plurality of electrical energy storage cells of an energy store, each of said electrical energy storage cells being connected by its pole via an electrically and thermally conductive contact assembly to a printed circuit board, said printed circuit The plates are arranged to separate a current received by each electrical energy storage cell through the contact assembly from a heat flow received through the contact assembly.

Description

technical field [0001] The present invention relates to an energy storage device for a vehicle, and more particularly to a device for contacting and cooling the electrical energy storage cells of the energy storage. Background technique [0002] In many applications that require the storage of electrical energy, especially vehicles with electric drives or electric motors, it is necessary to provide sufficient power and store the power in an energy storage device of the vehicle. [0003] Such as figure 1 As shown, an energy storage is currently used, such as electric road vehicles. exist figure 1 In existing reservoirs shown, or for automobiles, wheel, pouch or diamond-shaped battery packs, which use poles with upper or lower sides. The electrical connections under the individual cells or energy storage cells are primarily made by resistance welding. In this respect, the poles P of the energy store ESZ connected by spot welding, for example in each case by means of severa...
