A cell holder for accommodating a plurality of battery cells of a traction battery may include a base body, at least two first receptacles disposed on a first side of the base body, and at least two second receptacles disposed on a second side of the base body opposite the first side. The at least two first receptacles and the at least two second receptacles may each be configured to accommodate a single battery cell of the plurality of battery cells. The cell holder may also include at least one area including a phase change material.

Cell holder for holding battery cells of a traction battery

A battery module comprising a plurality or a multiplicity of battery cells which are positioned in a battery module housing, wherein the battery module housing comprises side walls (), a base surface and a battery module cover (), wherein the battery module cover () comprises at least one terminal () for the current-carrying or data-conducting contacting of the battery module (), wherein the terminal () is provided with a current-carrying or data-conducting cable (), and wherein the battery module cover () comprises a device () for the coiling of said current-carrying or data-conducting cable ().

Battery module, battery pack containing same, and use thereof

A battery cell, specifically a lithium-ion battery cell, having a prismatic battery cell housing (), in which the electrochemical components of the battery cell () are accommodated, and further comprising a thermal equalization element (), which is configured for the enhancement of thermal conductivity, which is arranged on a smallest lateral surface () of the battery cell housing (), such that a region () of the smallest lateral surface () which is not covered by the thermal equalization element () at least partially encloses said thermal equalization element ().

Battery cell, battery module, and application of such a battery module

The invention relates to a current sensor comprising an electric conductor (), through which a first current (I) can flow parallel to a first direction (R) and which comprises three regions () immediately following on from each other in the first direction (R). A middle region () of the three regions () comprises a conductor cross-sectional area that is smaller than a conductor cross-sectional area of each of the two outer regions () of the three regions (). A voltage sensor of the current sensor is designed to measure a first voltage between the two terminals () thereof. The first voltage is the same as a voltage applied to a measuring region () at least partially coinciding with the middle region (). An evaluation unit of the current sensor is designed to determine an existing current value of the first current (I) in accordance with an existing voltage value of the first voltage and a pre-defined resistance value of a first resistance of the measuring region ().

Current sensor and battery comprising such a current sensor

The invention relates to a receptacle () for at least partially compressively receiving at least one battery cell () for a battery module, wherein the receptacle () has at least two end plates () which can be arranged on two opposing sides of the at least one battery cell (), wherein the end plates () are connected to one another by a plurality of connecting means (), which are fixed to the end plates () and in each case have at least two plug elements (), in such a way that the plug elements () of the connecting means () for fixing the connecting means () to the end plates () engage in bushings () of the end plates () in a plane arranged substantially at right angles to the direction of extension of the connecting means (). In summary, a receptacle () of the type described above allows battery cells () in a particularly simple and cost-effective manner to be fixed in a battery module and allows the performance of a battery module to be maintained, irrespective of the temperature, by at least temporary bracing.

Receptacle for a battery module and battery module having such a receptacle

The invention relates to a retaining device for at least one battery cell, wherein the retaining device comprises at least two retaining elements, wherein each retaining element comprises at least one fastening means, wherein the at least two retaining elements are mechanically detachably connected by means of the fastening means.
