Description

The invention relates to a battery holder for rod-shaped batteries and to a battery module, in particular for electromobility applications.

Hybrid vehicles and all-electric vehicles are provided with a battery module for storing electrical energy for a traction drive of the vehicle. Such battery modules typically include a battery holder adapted to support a plurality of block or bar shaped batteries. The batteries are usually arranged in the battery holder such that their electrode terminals are placed on the same plane. This facilitates electrical contacting of the electrode terminals of the batteries. The battery holder can be attached directly or indirectly to the vehicle structure. The arrangement is also possible in a separate housing to be fastened to the vehicle structure.

A battery module with such a battery holder is for example from the DE 11 2015 000 913 T5 known.

The battery holder or battery modules are to be designed in particular for electromobility applications in such a way that the batteries are as well protected against mechanical stresses as they may occur during operation, from mechanical stresses that can lead to damage to the batteries.

It is therefore an object of the invention to provide a battery holder and a battery module with improved protection of the batteries from mechanical stress and are thereby inexpensive to manufacture.

The battery holder according to the invention has the features specified in protection claim 1. The task concerning the battery module is achieved by a battery module according to protection claim 14.

The battery holder according to the invention is used to hold a plurality of rod-shaped, preferably cylindrical, batteries and comprises a first and a second support plate, each having a plurality of adjacent openings with a uniform or substantially uniform opening cross-section. The support plates are arranged such that their openings are aligned in pairs in the direction of the longitudinal axis of the battery carrier in pairs. As a result, the batteries can each be inserted into an opening of the first and into an opening of the second support element.

According to the invention, a first elastomer bearing part is fastened to the first support plate, and a second elastomer bearing part is fastened to the second support plate. The two elastomeric bearing parts each have a multiplicity of battery through-openings arranged next to one another with a spatial distribution pattern corresponding to the openings of the two support plates. It is essential that battery through openings of the two elastomer bearing parts in the unloaded state of the elastomer bearing parts each have a clear width which is smaller than the opening cross section of the openings of the two support plates. As a result, the batteries to be supported on the battery holder can be gripped by the elastomer bearing parts in each case, preferably in a fully-enveloped manner, and stored floating on the support plates. By attached to the two support plates elastomeric bearing parts shocks or shocks that act on the battery case during operation, be damped, so that the batteries can be protected from damage more reliable.

The elastomeric bearing parts can in particular be made in one piece. As a result, these are inexpensive to produce and very easy to assemble. The elastomer bearing parts can be embodied in particular as injection-molded parts, which offers cost advantages in mass production of the elastomer bearing parts and enables a high dimensional stability of the elastomer bearing parts.

The two support plates can be provided according to the invention, preferably at the edge, each with a peripheral wall profile, which extends away from the respective support plate in the axial direction. The support plates can be attached to each other via the two wall profiles. Thereby, the number of required components of the battery holder can be minimized. This offers cost advantages in the production. The support plates form in this design with their respective wall profile in each case a housing shell. In the case of a fully sealing bearing of the elastomeric bearing parts on the batteries to be arranged in / on the battery holder, the interior space in the region of the openings of the support plates can be sealed to the outside in a fluid-tight or pressure-tight manner.

The two wall profiles of the support plates can in particular be welded together or screwed together according to a preferred embodiment of the invention. Also, a locking connection or a toggle connection of the two wall profiles is conceivable. If the locking connection is made detachable, defective batteries can be replaced if necessary.

Between the two wall profiles can be arranged according to the invention, an annular sealing element. The sealing element is preferably made of a rubber elastic deformable material. As a result, a circumferential sealing of the two wall profiles of the support plates can be achieved.

The protection of the batteries to be arranged in the battery holder or arranged according to the invention can be further improved by the fact that the two support plates and / or the two wall profiles of the support plates are at least partially or completely double-walled. Thereby, the mass of the battery holder can be further reduced and at the same time a sufficiently large load capacity of the battery holder can be ensured. Such a lightweight construction is particularly advantageous in mobile applications. Also, the battery holder in case of accidents, d. H. In the event of a crash, the batteries in or on them are better protected against mechanical damage.

Most preferably, the elastomeric bearing parts are designed for a circumferentially sealing contact with the batteries. The battery passage openings of the two elastomeric bearing parts can be circumferentially limited according to the invention in each case by a sealing lip of the elastomeric bearing parts. As a result, a particularly reliable circumferentially sealing system of the elastomeric bearing parts on the batteries can be achieved. The sealing lip may have one or more sealing edges for external contact on one of the batteries for the purpose of a spatially defined contact pressure curve. It should be noted that toxic or ignitable outgassing or leaking from the batteries fluid can be retained within the battery holder by the peripheral sealing of the elastomeric bearing parts in a corresponding design of the battery holder even in case of damage to the batteries.

If the sealing lips of the respective elastomer bearing part extend axially away from the elastomer bearing part in the direction of the respective other elastomer bearing part, the sealing lips can thereby be pressure-activated. In this case, the sealing lips can be pressed against a pressure proportional to a pressure prevailing between the two support plates space proportional to a prevailing in this room atmosphere or fluid pressure against the batteries. In the case of a bursting of the batteries, this allows a more reliable safety enclosure of the batteries to be achieved and an undesirable escape of toxic and / or ignitable fluids from the batteries into the surroundings of the battery carrier counteracted. The reliability of the battery carrier can be further increased. It is understood that the battery carrier in this regard may be equipped with a safety valve or the like to allow, if necessary, a controlled escape of the aforementioned fluids.

From production-technical point of view, it has been found to be particularly advantageous if each attachment extensions are integrally formed on the two elastomer bearing parts, which each hineinerstrecken in the axial direction in corresponding mounting recesses of the respective associated support plate. Such Befestigungsfortsätze are therefore an integral part of the elastomeric bearing parts. The attachment extensions of the elastomeric bearing parts can thus be arranged according to the invention held in the mounting recesses in the radial interference fit and / or engage behind the respective support plate or an undercut of the support plate at least in sections.

The attachment extensions of the elastomer bearing parts may in particular have an extended (= thickened) holding section. Also, the attachment extensions may each be provided with an inner support structure by which the attachment sections (resistant to bending) are stiffened. As a result, the elastomer bearing parts can be introduced in a simplified manner into the fastening recesses or pressed into them. An undesired buckling of the fastening sections during insertion into the fastening recesses can be counteracted thereby.

According to a particularly preferred embodiment of the invention, the battery carrier to a fluid inlet for a Wärmeübertrager- or tempering fluid and a fluid outlet for the fluid, which are fluidly connected to an arranged between the two support plates interior of the battery holder. As a result, the batteries to be arranged in the battery holder can be flowed around by means of the tempering fluid. This allows the batteries during operation of the battery holder, for example, at low operating temperatures, heated or, at high outdoor temperatures or high discharge or charging currents of the batteries, cooled. Depending on the characteristics of the batteries used, the service life or performance of the batteries can be decisively improved.

A particularly cost-effective production of the battery holder can be realized that the first and the second support plate made of a plastic material. Thus, the two support plates can be designed, for example cost and high dimensional accuracy as injection molded parts. This offers cost advantages especially in mass production of the battery holder.

The battery module according to the invention is particularly suitable for electric mobility applications and in this regard may be embodied as a traction battery module. The battery module comprises a plurality of preferably rod-shaped batteries, which are arranged in a battery holder according to one of the preceding claims. According to the invention, the battery holder preferably has an inner space which is sealed to the outside during operation of the battery module and can be flowed through to a predetermined temperature value by means of a heat transfer fluid in order to temper the batteries. The support plates are in the structurally simplest case each part of a housing shell, which are fastened to each other via their peripheral wall profiles.

The batteries are preferably all of identical design and can in particular correspond to each other corresponding electrical parameters, ie. H. Rated voltages, capacities, etc. have.

It will be understood that each of the batteries may comprise one or more electrochemical cells in a manner known per se.

Further advantages of the invention will become apparent from the description and the drawings. Likewise, according to the invention, the above-mentioned features and those which are still further developed can each be used individually for themselves or for a plurality of combinations of any kind. The embodiments shown and described are not to be understood as exhaustive enumeration, but rather have exemplary character for the description of the invention.

The batteries 14 are cylindrical here and preferably have a uniform outer diameter 16 on. The batteries 14 each extend in a direction to the longitudinal axis 18 of the battery holder 12 parallel direction. For a simplified electrical contacting of the batteries they are in the axial direction with their positive electrodes 20 the batteries 14 and their negative electrodes 22 in the battery holder 12 all preferably arranged aligned in the same direction.

The battery holder 12 has a first support plate 24 and a second support plate 26 on, which are each designed as so-called perforated plates. The two support plates 24 . 26 Consequently, each have a plurality of adjacent openings 28 on. The openings 28 are here circular or substantially circular executed. In addition, the openings point 28 a uniform or substantially uniform opening cross-section 30 on. The openings 28 are in other words the same size. The openings 28 can get through the respective support plate 24 . 26 each in the direction of the longitudinal axis 18 of the battery holder 12 extend therethrough and so as Durchgangsausnehmungen the support plates 24 . 26 be executed. The batteries 14 can in this case in the axial direction through the support plates 24 . 26 extend therethrough, whereby the electrical contact of the batteries 14 can be further simplified. It should be noted that the openings 28 the two support plates 24 . 26 at the in 1 shown mounted state of the battery holder 12 in the direction of the longitudinal axis 18 of battery holder 12 each pair are aligned in pairs, so that the batteries each in an opening 28 the first support plate 24 and in an opening 28 the second support plate 26 can be used.

On the two support plates 24 . 26 Here is each edge of a circumferential wall profile 32 molded, which differs from the respective support plate 24 . 26 extends in the axial direction.

The wall profiles 32 For example, can be welded together circumferentially or bolted together in a manner not shown. It is also conceivable that the wall profiles 32 locked together. Between the two wall profiles 32 may be an annular sealing element 40 be held held in the radial and / or axial interference fit. This can be an interior 42 of the battery holder 10 in the area of wall profiles 32 circumferentially sealed in the radial direction.

The two support plates 24 . 26 and / or the molded wall profiles 32 can under consideration of the crash safety of the battery module 10 executed double-walled and therefore realized in hollow profile design.

The support plates 24 . 26 are at their respective other support plate 24 . 26 assigning page 44 each with an elastomeric bearing part 46 . 48 Mistake. A first elastomeric bearing part 46 is on the first support plate 24 and a second elastomeric bearing part 48 is on the second support plate 26 attached.

The two elastomeric bearing parts 46 . 48 are here each made in one piece and elastically deformable. According to 1 show the two elastomeric bearing parts 46 . 48 each a plurality of juxtaposed battery passage openings 50 on.
