Problems solved by technology

However, the disadvantage of this substitute or analog device is that it does not have the physical characteristics of the original battery cell, so most of them differ in terms of weight, heat capacity, thermal conductivity, center of gravity of the machine, vibration characteristics when excited, etc.
These distinctions will detract from the persuasiveness of the test or adjustment (Abstimmung), thereby necessitating the need for other tests or leaving residual uncertainty

Embodiment Construction

[0026] exist figure 1 An original battery cell of the lithium-ion cell type is shown in . The original battery cell comprises a cathode 2 and an anode 4 , which are arranged in a casing 1 . The cathode 2 is electrically conductively connected to the cathode terminal 3 and the anode 4 is also electrically conductively connected to the anode terminal 5 . Both the cathode 2 and the anode 4 are in direct contact with an electrolyte 6 which is likewise arranged in the housing. The cathode terminal 3 and the anode terminal 5 are connected by wires with line resistance 7 to a voltage source 8 which provides a suitable charging voltage, such as 3.6V.

[0027] In lithium-ion battery cells used today, the material of the anode 4 consists essentially of graphite and the cathode 2 contains LiCoO 2 Or lithium manganese oxide, lithium nickel oxide or a mixture of aluminum-based stabilized oxides. The electrolyte 6 can for example contain as solvent a mixture of organic carbonates, for e...

Abstract

The present invention relates to a dummy battery cell which has a housing (1), electrodes (2, 4) arranged within the housing (1), and terminals (3, 5) which are electrically conductively connected to the electrodes (2, 4), with the dummy battery cell being designed such that the housing (1) can hold an electrolyte, characterized in that, instead of an electrolyte, the dummy battery cell has a filler (9) which does not contain an electrolyte that is effective for that battery cell type. Furthermore, the invention relates to a battery, to a battery module and to a battery system which contains at least one such dummy battery cell.

Description

technical field [0001] The invention relates to a battery cell simulation device comprising a housing, electrodes arranged in the housing, and terminals electrically conductively connected to the electrodes, wherein the battery cell simulation device is configured such that an electrolyte can be accommodated in the In the housing, the battery cell simulator includes a filler in place of the electrolyte. Furthermore, the invention relates to a battery, a battery module and a battery system comprising at least one such battery cell simulator. Background technique [0002] When developing battery systems, especially for the automotive market (currently based, for example, on lithium-ion technology), the battery cells, the battery management system (BMS) and all other controllers must be coordinated with each other in such a way that the safety of people and / or The material is safe to work with without hazards. First of all, at the beginning of a new development activity in a ...
