Description

  • The present invention relates to a module housing for a stackable battery module, wherein a plurality of battery modules are stackable in a stacking direction to a battery stack, comprising a bottom portion and a peripheral wall portion. Furthermore, the invention relates to a battery module for a battery stack with a module housing and a plurality of battery units, wherein the battery units are arranged in the module housing. Moreover, the present invention relates to a battery stack of a plurality of battery modules stacked in a stacking direction.
  • Electrical energy storage devices are widely used in modern technology, for example in electric vehicles. Possible embodiments of such energy storage are, for example, lithium-ion batteries. In order to increase the performance of such batteries, it is known to combine a plurality of battery cells as battery units in a module housing to form a battery module and electrically connect in parallel. In order to further increase the electrical performance of such batteries, two or more of these battery modules may be stacked into a stack of batteries in a stacking direction, wherein the individual battery modules may be electrically connected in series.
  • In an operation of such a battery stack, but also during operation of a single battery module, there may be a significant heat development. Temperature control, in particular cooling, of the battery modules, in particular of the individual battery units, which are arranged in the individual battery modules, is thus usually unavoidable. Preferably, for a cooling, in particular in order to be able to provide a particularly high cooling capacity, a fluid, in particular liquid temperature, can be used.
  • In order to prevent an unwanted escape, in particular a tempering liquid, a sealing is known and necessary in known battery modules in principle. According to the prior art, it can be provided in particular to seal each individual battery unit itself. This has proven to be problematic, especially in the case of large battery stacks, since several times 1000 battery units can often be installed in these battery stacks. A sealing of each individual battery unit is in this case very comprehensive and associated with a large manufacturing effort, both in terms of the time required for a production and work as well as in terms of the costs incurred.
  • It is therefore an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to provide in a cost effective and simple manner a module housing for a stackable battery module, a battery module and a battery stack, by which a particularly simple, yet secure seal, in particular against leakage of a tempering fluid, can be provided or improved ,
  • The object is achieved by a module housing for a stackable battery module with the features of independent claim 1. Further, the object is achieved by a battery module for a battery stack with the features of independent claim 12. In addition, the object is achieved by a battery stack with the features of the independent claim 13. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. In this case, features and details that are described in connection with the module housing according to the invention apply, of course, in connection with the battery module according to the invention and the battery stack according to the invention and in each case vice versa, so with respect to the disclosure of the individual aspects of the invention always reciprocal reference is or can be.
  • According to a first aspect of the invention, the object is achieved by a module housing for a stackable battery module, wherein a plurality of battery modules are stackable in a stacking direction to form a battery stack, comprising a bottom section and a peripheral wall section. An inventive module housing is characterized in that the wall portion and the bottom portion pot-like surround a receiving space for receiving battery units of the battery module, further comprising at an end remote from the bottom portion of the wall portion at least one circumferential sealing device for sealing the receiving space against the bottom portion of a subsequent module housing in the stacked Condition of the battery modules is arranged.
  • An inventive module housing is provided for providing a housing for a stackable battery module. To produce a battery stack, battery units can be arranged in the individual module housings and the battery modules thus provided can then be stacked in a stacking direction to form the battery stack. By an electrically conductive connection, for example, an electrically parallel connection of the individual battery units of a battery module and an electrically serial connection of the individual Battery modules, can be provided in this way a battery pack with a high electrical performance.
  • A module housing according to the invention has at least one bottom section, which merges laterally into a peripheral wall section or is delimited by it. In this way it can be provided that the bottom portion together with the wall portion pot-like surrounds a receiving space or forms this. The bottom section can transition in particular in the stacking direction above or alternatively below into the peripheral wall section. Preferably, the transition from the bottom section into the wall section can be made fluid-tight, preferably liquid-tight, whereby the pot-shaped receiving space essentially has only one access opening, which is arranged in particular on an end of the wall section facing away from the bottom section and bounded by the wall section. This can be provided in a particularly simple manner, for example by integrally formed, in particular monolithic, the wall section and the bottom section.
  • In the case of a module housing according to the invention, it is provided that at least one peripheral sealing device is arranged at an end of the wall section facing away from the bottom section, which, as described above, delimits the access opening to the receiving space. Circumferential within the meaning of the invention may be understood in particular to mean that the at least one sealing device is arranged along the entire wall section, particularly preferably without interruption, and in this way completely surrounds the access opening of the receiving space described above. In particular, this circumferential sealing device is adapted to be provided for sealing the receiving space against a bottom portion of a subsequent module housing in the stacked state of the battery modules. In other words, the at least one sealing device in the stacked state of the battery modules may preferably be arranged between the wall section of a first module housing and a bottom section of a next module housing, as a result of which the receiving space of the first module housing as a whole can be sealed. An additional cover element for closing the access opening of the receiving space can be omitted. In other words, a module housing according to the invention forms the smallest self-contained unit in a battery stack whose battery modules have module housings according to the invention. Upon introduction of a tempering fluid, for example a tempering liquid, into the receiving space, the battery units in the receiving space can be tempered in this way, in particular cooled or heated, without allowing tempering fluid to escape to the outside. In particular, this also avoids having to provide a separate seal for each of the battery units. A battery module with a module housing according to the invention can thus be made simpler, faster and, in particular, less expensive.
  • In addition, in the case of a module housing according to the invention, it can be provided that the wall section has a circumferential arrangement region for arranging a counter arrangement region of the further module housing, wherein the at least one sealing device is arranged on the arrangement region. Such an arrangement region can, for example, have a suitable shape in order to form a form, frictional and / or frictional connection with the corresponding counter-arrangement region of the further module housing, whereby stacking of the individual battery modules having module housings according to the invention can be simplified to form a battery stack. Since these arrangement regions or the counterranging regions thus form those sections of the module housing which at least come very close or even touch during stacking, they are preferred areas for arranging the at least one sealing device. By circulating the arrangement region in turn, on the one hand, a particularly good and safe stackability of the battery modules as well as a particularly good and in particular complete sealing of the receiving space of the module housing can be ensured.
  • Also, a module housing according to the invention can be further developed such that the arrangement region has an adhesive section for bonding to a counter-adhesive section at the counter-arrangement region of the further module housing. By gluing the two module housings together, provided by an adhesive portion at the arrangement area and a Gegenklebeabschnitt on Gegenanordnungsbereich, on the one hand, the stacking of the battery modules having such module housing according to the invention, to a battery pack as well as a seal of the receiving space of the module housing can be further improved. The provision of dedicated adhesive portions or counter-adhesive portions may in particular help to reliably avoid contamination with adhesive to be kept free areas, such as the sealing device. A sealing of the receiving space by the at least one sealing device can thus be provided preferably without influencing by the additional bonding performed.
  • In addition, a module housing according to the invention can be further developed such that the arrangement region in the stacked state of the module housing is designed to overlap in the stacking direction in an overlapping region with the counterposition region, wherein the at least one sealing device is arranged in the overlapping region. By such an overlap region of the arrangement area and the counter arrangement area, a seal of the accommodating space of the module housing can be further improved because, for example, by overlapping the arrangement area and the counter arrangement area, at least a labyrinth seal can be formed. An escape of tempering fluid, in particular tempering, out of the receiving space to the outside of the battery stack can be prevented even better in this way.
  • According to a particularly preferred further development of a module housing according to the invention, it can further be provided that the at least one sealing device is arranged transversely to the stacking direction in the overlapping region of the arrangement region. Transverse to the stacking direction according to the invention may be formed in particular perpendicular to the stacking direction. In this way, in particular a load-free arrangement of the at least one sealing device can be provided. A mechanical stress of the at least one sealing device, for example, by a weight of the battery modules arranged above, can be prevented in this way, or at least significantly reduced.
  • It can also be provided in a module housing according to the invention further that the at least one sealing device is molded onto the wall portion, in particular molded in a two-component injection molding process. By such injection molding, in particular, a particularly good connection of the at least one sealing device to the wall section can be provided. Moreover, when using a two-component injection molding process, the module housing can be produced together with the at least one sealing device by a suitable choice of the materials used, wherein in particular the properties of the various sections can be adjusted particularly flexibly. A production of a module housing according to the invention can be further simplified and improved in this way.
  • In addition, it can be provided in a module housing according to the invention that the at least one sealing device has at least two spatially separated sealing elements. In this way, a redundancy of the seal provided by the at least one sealing device can be made possible. In particular, in case of failure of one of these spatially separated sealing elements, the seal can still be provided by the at least one second sealing element. A reliability of a seal of a module housing according to the invention can be provided in this way, or at least significantly increased.
  • A module housing according to the invention can also be characterized in that the bottom section has battery receptacles for receiving battery units with contact openings for, in particular, electrical contacting of the battery units, wherein in the arranged state of the battery units the contacting openings are sealed by the respective battery unit or at least substantially sealed. Such battery receptacles can in particular provide a positive, frictional and / or non-positive retention of the battery units in the receiving space of a module housing according to the invention. To increase the electrical performance of the battery module with such a module housing according to the invention, a contacting of the individual battery units can be provided. The contacting openings can be provided for this purpose, wherein the contacting openings, in particular in the bottom section, can be formed as continuous openings, so that contacting from outside the module housing, in particular starting from a further module housing arranged below the module housing, is also possible. By sealing the contacting openings by the battery units themselves, in particular a saving of further sealing elements can be made possible. Overall, in this way a particularly simple, safe and, moreover, designed with low weight embodiment of a module housing according to the invention can be provided.
  • According to a further development of a module housing according to the invention, it can further be provided that the battery receptacles each have at least one adhesive surface for gluing the respective battery unit into the battery receptacle. With respect to the battery units in the battery holders can be further increased by an adhesive bond, a sealing of the receiving space and an attachment of the battery units in the respective battery receptacle of the bottom portion. An even better sealing of the receiving space even in the presence of contact openings can be provided in this way.
  • Particularly preferred may also be provided in a module housing according to the invention in that the wall section has a tempering fluid supply line for supplying a tempering fluid and a tempering fluid discharge for discharging the tempering fluid, wherein the tempering fluid supply line has a tempering fluid inlet for introducing the tempering fluid into the receiving space and the tempering fluid discharge has a tempering fluid outlet for discharging the temperature control fluid from the receiving space. In this way, in other words, the receiving space can be flooded with tempering fluid, in particular with a tempering liquid, wherein in particular by the presence of a Temperierfluidzulaufs and Temperierfluidablaufs also a particular permanent and uniform flow through the receiving space can be provided by the Temperierfluid or Temperierflüssigkeit. A particularly good temperature control of all battery units, which are arranged in the receiving space of the module housing, can be provided in this way.
  • According to a preferred further development of a module housing according to the invention, it can further be provided that the tempering fluid supply line and / or the tempering fluid discharge line have connection sections for fluid-communicating connection to mating connection sections of a further module housing. When the battery modules are stacked with module housings according to the invention, the temperature-control fluid supply lines and / or the temperature-control fluid discharge lines of the individual module housings can thus be connected to one another via the respective connection section and the respective mating connection section so as to be fluid-communicating and preferably sealed to the outside. In other words, in a stacking of the module housing to a battery stack, a continuous Temperierfluidzuleitung and / or a continuous Temperierfluidableitung be provided by the entire battery stack. In this way, a common temperature of all receiving spaces of all module housing can be provided, in particular, not every single module housing must be supplied separately with Temperierfluid. A temperature control of the entire battery stack can be significantly simplified in this way.
  • According to a second aspect of the invention, the object is achieved by a battery module for a battery stack with a module housing and a plurality of battery units, wherein the battery units are arranged in the module housing. An inventive battery module is characterized in that the module housing is formed according to the first aspect of the invention.
