Description

The invention relates to a battery according to the preamble of patent claim 1 and a motor vehicle with such a battery.

Batteries known from the prior art, in particular high-voltage batteries, for vehicle applications consist of many individual cells connected in series and / or in parallel, which are located together with the associated electronics and cooling in a common housing. The cells are grouped in so-called cell blocks, each containing a certain number of cells including their mechanical fixation, contacting and means for cooling / heating. The cooling or heating plates are directly traversed by a fluid such. As water, air conditioning, air, or are equipped with refrigeration or heat sources, such. B. Peltier elements, heating pads. They are arranged laterally on the cell block and are thermally coupled directly or via an electrically insulating and tolerance-compensating heat-conducting film or a potting compound with contact to the cell housing or to the cell poles or indirectly with contact to the cell connectors or cooling bars / cooling plates with the cells. For rectangular cells, such as. As flat cells such as pouch cells or prismatic cells, these and their holders, which are formed in pouch cells as a frame and prismatic cells as a spacer, or the complete cells in bipolar Rahmenflachzellen in which the frame is integrated into the cell over Clamping means compressed by pressure goggles. As a result, the cells are fixed substantially non-positively in their holders and a stable block is formed. However, increased by these additional parts, in particular the clamping means, weight, space requirements and costs of the battery.

The object of the present invention is therefore to provide a battery and a motor vehicle by means of which the most effective possible stabilization of the cells in a cell block is made possible.

This object is achieved by a battery with the features of claim 1 and a motor vehicle with such a battery according to claim 10. Advantageous embodiments can be found in the dependent claims.

The battery according to the invention has a plurality of battery cells arranged in a cell block, wherein the cell block has two opposite end faces delimiting the cell block in a longitudinal extension direction. Furthermore, the battery comprises at least one tempering device for tempering the battery cells, the tempering device being arranged on a side of the cell block which is different from the end faces of the cell block. Furthermore, the tempering device has at least one recess, which is formed with an extension direction at least partially parallel to the longitudinal extension direction of the cell block. In addition, the battery has at least one clamping element, wherein at least a part of the clamping element is arranged in the at least one recess of the tempering device. In this case, the tensioning element is fastened to the battery in such a way that, at least indirectly, a compressive force can be exerted on each of the end sides of the cell block at least partially parallel to the longitudinal direction of extension of the cell block by the tensioning element.

The recess in the tempering device thus advantageously makes it possible to embed a part of the tensioning element in the tempering device and thus to provide an extremely compact and space-saving stabilization of the battery cells. In addition, the recess also reduces the weight of the battery. The formation of the tempering device with a recess is also particularly simple and inexpensive. By means of the invention, a simple, cost-effective, weight-reduced and above all compact battery can thus be provided in a very effective manner, the battery cells of which can also be stabilized in their position by the tensioning element.

In an advantageous embodiment of the invention, the battery has at least one pressing element, which is arranged on one of the end sides of the cell block and which is coupled to the at least one clamping element such that at least one of the compressive forces by the clamping element on the contact element on the front side, at which the pressing element is arranged, is exercisable.

In this case, the pressing element may be formed, for example, as a flat and plate-shaped pressure plate or as a frame-shaped pressure goggles. By providing a contact pressure element, the compressive forces caused by the tensioning element can be exerted very uniformly on the end faces of the cell block, which holds or compresses the battery cell arrangement even more uniformly and stably in the cell block. In addition, by the partial arrangement of the clamping element in the recess of the tempering and by the coupling of the clamping element with the pressing element at the same time a holder or attachment of the cell block, the pressing and the tempering are provided to each other, so that additional fasteners can be saved. In this case, the coupling between the contact pressure element and the tensioning element is preferably configured in such a way that the contact pressure element is pressed against the end face of the cell block by the tensioning element and at the same time the pressure element is pressed against a End of the tempering or at least one pressing of the pressing in the direction of tempering. It is advantageous to provide two pressing elements, which are arranged on a respective end face of the cell block.

Furthermore, it is advantageous if the at least one tensioning element is designed to be elastic at least in part and in a direction parallel to the longitudinal extension direction of the cell block and is under tension. By this longitudinal elasticity and by the tensile load of the clamping elements can be avoided in a particularly advantageous manner thermal expansion differences and / or compensated. Also, set losses of the press association of the battery cells in the cell block can be compensated in an advantageous manner. In addition, stand by the design of the clamping element as separate from the tempering component more options ready to flexibly adapt the clamping element in terms of its elasticity properties and thermal expansion properties to given requirements, such. B. by a suitable choice of material and / or the geometric design for influencing the properties mentioned.

In addition, the at least one clamping element can be designed as a screw, in particular as a tie rod screw and / or as an expansion screw, and / or as a tension band. In such embodiments of the clamping element, the longitudinal elasticity can be achieved preferably and inexpensively by a small cross section thereof, in particular in relation to its length. The biasing force of the clamping element leads to an elastic extension of the clamping element (Dehnschraubeneffekt).

Thin and thus elastic clamping elements such as tie rods, threaded rods, screws or straps lead advantageously at Setzverlusten the interference fit only to low preload force losses. In addition, several clamping elements can be provided to increase the stability of the overall arrangement and / or to effect a uniform compression of the cell block.

Furthermore, tempering device may be plate-shaped, wherein the at least one recess of the tempering device is formed as a recess in a side facing away from the cell block of the tempering. By a plate-shaped design, in particular by a planar design of the cell block facing side of the tempering, a particularly good thermal coupling to the battery cells can be effected. To make this thermal coupling even more effective, a tolerance-compensating and electrically insulating heat-conducting foil or a potting compound between the cell block and the side of the tempering device facing the cell block can furthermore be arranged. Moreover, it is particularly advantageous to form the recess as a depression in the side of the tempering device facing away from the cell block, because this does not reduce the heat transfer surface between tempering device and the cell block. Furthermore, a simple mounting of the clamping elements on the tempering is made possible by the formation of the recess as a recess. In this case, the recess may extend over the entire side facing away from the cell block of the tempering or, if not the complete cell block length is required to achieve the necessary elasticity, even partially, in particular starting from one end of the tempering, so that the corresponding clamping elements shorter can be trained.

Furthermore, the at least one recess can be formed as a cavity in the tempering device with an insertion opening in the tempering device, so that at least part of the at least one tensioning element is inserted through the insertion opening at least partially parallel to the longitudinal extension direction of the cell block into the cavity. The recess may be formed, for example, as a through hole or complete perforation of the tempering in a direction parallel to the longitudinal direction of the cell pack, through which the clamping element is performed. Also, by the implementation of the clamping element by the tempering device space can be saved, and there are numerous options for adjusting the properties of the clamping elements independent of the tempering ready. The cavity formed as a cavity can also be connected to a recess formed as a recess, z. B. as a threaded hole, so that a trained as a screw clamping element can be arranged in the recess formed as a recess and secured in the threaded hole by screwing.

In a further embodiment of the invention, the temperature control is designed as a cooling and / or heating plate with a running in a first region of the cooling and / or heating plate channel system through which a fluid can be carried out. Such a design of the tempering device can be a particularly effective cooling and / or heating of the battery cells accomplish.

In a further preferred embodiment of the invention, the at least one recess in an edge region of the cooling and / or heating plate is arranged, which in one direction viewed perpendicular to the longitudinal direction of the cell block viewed outside the first region. With this configuration, the recesses and the channel system can be arranged in the most compact and space-saving manner possible, in particular without the recesses provided in the cooling plate impairing the cooling and / or heating circuit.

In a further preferred embodiment of the invention, the battery cells are formed as flat cells, which are arranged in the longitudinal direction of the cell block in series. The battery cells can be designed, for example, as pouch cells with frames, as prismatic cells with spacers, or as bipolar frame flat cells with an integrated frame. In all these embodiments, the invention advantageously allows a cost-effective and, above all, space-saving pressing of the cell block.

The coordinate systems shown in the figures are to be understood as a different representation of one and the same coordinate system.

1 shows a schematic exploded view of a battery 10 , in particular in a simplified representation, according to a first embodiment of the invention. The battery 10 has while a plurality of battery cells 12 on, which are designed as flat cells, wherein in the illustration shown for reasons of clarity, only a battery cell 12 is provided with a reference numeral. The flat cells can generally be formed arbitrarily, z. B. as pouch cells, as bipolar Rahmenflachzellen or, as shown here, as prismatic cells. The battery cells 12 , their two poles 12a at the top of the metallic housing of the battery cells 12 are arranged are by spacers, such as by so-called spacer 16 , z. B. plastic in a double shell shape, kept at a distance and electrically isolated from each other.

The contacting of the battery cells 12 , z. B. for an electrical series connection of the battery cells 12 , via cell connectors, by overlapping laser welding with the cell poles 12a get connected. The cell connectors are in a cell connector board 13 summarized, the top of the cell block 14 can be placed and attached. The battery cells 12 are still in a cell block 14 arranged, in particular in a longitudinal direction of the cell block 14 , which here corresponds to the x-direction of the drawn coordinate system, strung together with the larger-area sides 12b their cuboid geometry facing each other. There are two battery cells each 12 through a spacer between them 16 spaced. At the two end faces of the cell block 14 there is a spacer edge element 16a that the cell block 14 in its longitudinal direction at the respective end face to the outside.

Furthermore, below the cell block 14 , ie, counter to the z-direction, arranged a temperature control, in this example as a heating and cooling plate 18 is trained. To the cell block 14 to compress and thus the battery cells 12 non-positively in their holders, the spacers 16 , to fix, are on the front sides of the cell pack 14 furthermore respective pressing elements, in this example pressure goggles 20 arranged. Furthermore, the battery points 10 Clamping on, by means of which the pressure goggles 20 a pressure force on the respective end face of the cell block 14 exercisable. These clamping elements are in this example as Zugankerschrauben 22 educated. There are two of the tie rod screws 22 in a recess in the form of a groove 24 (see. 2 ) in a cell block 14 opposite bottom of the heating and cooling plate 18 arranged and two of the tie rod screws 22 run on the cell block top through in the spacers 16 and the spacer edge elements 16a provided through holes 16b , It is also possible through the spacer 16 extending clamping elements other than those in the recess of the heating and cooling plate 18 form extending clamping elements, z. B. as pressure-resistant steel inserts in the spacers. Furthermore, the tie bolts 22 also through the pressure goggles 20 carried out. The lower tie rod bolts 22 are doing so on the battery 10 attached that the pressure goggles 20 between screw heads 22a the tie rod screws 22 and the heating and cooling plate 18 or between on the tie rod screws 22 screwed nuts 22b and the heating and cooling plate 18 , In the same way are the top tie rod screws 22 on the battery 10 attached, so that the pressure goggles 20 between the screw heads 22a or the nuts 22b the respective tie bolts 22 and the spacer edge elements 16a are located.

These tie rod bolts 22 are elastic in the x-direction. This is due to a very thin cross section of these tie rod bolts 22 , At least whose shaft, in particular in comparison to their length in the x-direction causes. The tie bolts 22 are tightened so that they are under tension and thus biased. The bias leads to an elastic extension of Zugankerschrauben 22 , Through this training of the battery 10 can the pressure goggles 20 For a particularly effective against the end faces of the cell block 14 be pressed and thus an extremely stable compression of the cell block 14 provided by the tie rod bolts 22 in this way, the entire arrangement stably held together, ie the cell block 14 , the heating and cooling plate 18 and the pressure goggles 20 , without the need for additional fasteners are required.

The integration of these as tie rod screws 22 trained clamping elements in the heating and cooling plate 18 is due to the design of the heating and cooling plate 18 with grooves on the cell block 14 turned away side designed so that the heat transfer surface between the cooling or heating plate and the battery cells 12 not reduced. Advantageously, this integration no additional space for the clamping elements required and the full heat transfer surface between the battery cells 12 and the heating and cooling plate 18 remains. The longitudinal elasticity of the tie rod screws 22 ensures that when settling of the press association of spacers 16 and pressure goggles 20 the necessary biasing force is maintained for the function. Through this training thermal expansion differences can be further avoided or reduced, for. B. in that the material of Zugankerschrauben 22 , which are below in the groove 24 the heating and cooling plate 18 are guided, and by the spacers 16 performed tie bolts 22 the same thing is, for. Steel. Furthermore, thermal expansion differences and their effect on the biasing force can be reduced by the longitudinal elasticity of the clamping means.

Furthermore, the heating and cooling plate 18 an inlet opening 28 and an outlet opening 30 for supplying and discharging the fluid. Furthermore, the geometry of the groove 24 adapted to the geometry of the clamping elements. The groove can 24 be designed so that the clamping means, such. B. the tie bolts 22 , or other types of clamping devices such as expansion screws 122 (see. 6 ) or tension bands 222 (see. 8th ), with the part passing through the groove 24 is performed completely within the groove 24 are arranged, ie not on the heating and cooling plate 18 protrude in the z-direction. Furthermore, the groove width is preferably formed so that the clamping elements in and against the y-direction is not frictionally engaged with the boundary surfaces of the groove 24 abut, so that an elastic deformation of the clamping elements is not affected.

The recesses are in an edge region of the heating and cooling plate 18 arranged, not by the coil 26 is going through. This allows a particularly compact design of the heating and cooling plate 18 and thus the battery 10 per se. The pipe coil 26 can thus be arranged unimpaired in the y-direction between the recesses. Furthermore, so must the heating and cooling plate 18 in their extension in the z-direction also not be made thicker and the heat exchange surface between the heating and cooling plate 18 and the battery cells 12 is not reduced. As in the illustrations in 3 and 4 to see is still between the heating and cooling plate 18 and the battery cells 12 a thermal coupling element 32 arranged, the z. B. may be formed as an electrically insulating and tolerance compensating heat conducting film or a potting compound.
