Definitions

  • the invention relates to a battery, in particular a lithium-ion battery for a vehicle, in particular a battery for a vehicle with hybrid drive or a fuel cell vehicle, according to the features of the preamble of claim 1.
  • Batteries are known in the prior art, in which a plurality of arranged in series and / or parallel individual cells are arranged and form a cell block.
  • This cell block must be cooled to dissipate the resulting heat loss of the individual cells. This is done by liquid cooling or by cooling by means of pre-cooled air, which is passed directly between the individual cells. For reasons of space, liquid cooling is preferably used.
  • a cooling plate through which refrigerant flows is arranged on the cell block. In the longitudinal direction of the individual cell, the heat is conducted either through separate cooling rods or through the cell wall of the individual cells, which is partially or uniformly thickened on the circumference, to the cooling plate.
  • the heat technology connection of the individual cells to the cooling rods is material and form-fitting by potting compound. At the same time, the potting compound takes on the electrical insulation and fixes the individual cells in the cell assembly.
  • Another disadvantage is the positioning of the individual cells relative to the cooling plate. This is affected by the accuracy of the potting device prior to final assembly. Between the single cells and the cooling plate arises Production-related gap, whose expansion is variable depending on the manufacturing tolerances of the casting device.
  • the invention has for its object to provide a battery with an improved attachment of the individual cells.
  • a plurality of individual cells connected in series and / or in parallel with one another are arranged in a battery, in particular a lithium-ion battery.
  • the individual cells are freely arranged at one of the ends in recesses of a holding plate and fixed at the opposite end.
  • the individual cells Due to the fixation of the individual cells at one end and the free arrangement of the other ends of the individual cells in recesses of a retaining plate, the individual cells are securely fastened in the battery housing. At the same time, however, a thermal expansion of the individual cells in the axial direction in the recesses of the holding plate is made possible. Since the fixation of the individual cells at the pole end is preferably carried out on a cooling plate, in this way, a comparison with the prior art optimized heat dissipation of individual cells is achieved on the cooling plate, since no arises depending on tolerances variable manufacturing gap between individual cells and cooling plate. The use of height tolerance compensating cell connectors is no longer necessary, since the thermal expansion of the cells in the axial direction is completely in the direction of the housing bottom of the battery.
  • the single cells Due to the arrangement of the individual cells in the recesses of the holding plate before the battery assembly, the single cells can easily with the pushed the other end to the cooling plate and then fixed there, since an axial displacement of the individual cells in the holding plate is possible. This facilitates the installation of the battery.
  • the holding plate is formed such that a plurality of recesses are arranged in series and a plurality of rows of recesses in parallel offset in each case by half a recess order, and thus a honeycomb structure of the holding plate is formed.
  • This arrangement of the recesses increases the packing density of the individual cells arranged therein, which leads to a reduction in the installation space requirement of the battery, which is particularly desirable when using the battery in vehicles.
  • the retaining plate also serves as an electrically insulating spacer between the individual cells.
  • the formations of the recesses of the retaining plate preferably correspond with formations of a jacket of the individual cells. If the sheathing of the individual cells is cylindrical, the holding plate contains round recesses whose diameters correspond to the cross section of the sheath of the individual cells.
  • the recesses of the holding plate in shape and dimension also correspond with these to the outer dimensions and shapes of the individual cells.
  • the recesses in the holding plate are shaped in such a way that they correspond to the contours of the sheath of the individual cells. In this way, the individual cells are stored stable against radial position changes and rotational movements.
  • the cooling plate is preferably arranged. This cooling plate is provided with recesses for carrying out the cell poles of the individual cells.
  • the individual cells are firmly fixed on the pole side to the cooling plate. In this way, a good thermal connection of the individual cells to the cooling plate is ensured, so that the heat loss of the individual cells can be optimally dissipated.
  • a heat-conducting foil can be arranged between the pole side of the individual cells and the cooling plate to further improve the thermal connection.
  • the recesses of the cooling plate preferably correspond with the dimensions of the cell poles of the individual cells.
  • At the top of the cooling plate cell connectors are also arranged. By these cell connectors, which are placed on the guided through the recesses of the cooling plate cell poles of the individual cells, the individual cells are connected in series and / or parallel to each other and attached to the cooling plate.
  • the individual cells are positively connected to the cooling plate and retaining plate and fixed against radial movements and rotational movements.
  • holding plate and cooling plate support the inserted single cells against lateral movements.
  • the individual cells are at least secured by the fact that the contours of the recesses for the pole contacts in the cooling plate are not round, but correspond to the outer contours of the pole contacts and lie in a form-fitting manner to this.
  • a rotational movement of the pole contacts and thus the individual cells is no longer possible.
  • the individual cells are not round in design, but, for example, polygonal, or the casing of the individual cells is partially thickened, a rotation movement of the individual cells is prevented by the holding plate, since the inner contours of the recesses in the holding plate with the outer contours of the individual cells correspond and form-fitting manner abut the individual cells.
  • the retaining plate, the individual cells arranged therein, the cooling plate arranged on the pole side of the individual cells and the cell connectors are arranged as an integrated structural unit in a battery housing.
  • the battery case is expediently closed with a housing cover from above and with a housing bottom from below.
  • a free space is formed between the housing bottom and bottom part of the individual cells.
  • this free space in the individual cells can expand in the axial direction due to heat, without being damaged or damage other parts of the battery.
  • the battery is particularly suitable as a vehicle battery, in particular as a battery for a vehicle with hybrid drive or a fuel cell vehicle.
  • the advantages achieved by the invention are in particular that the secure attachment of the individual cells can be ensured in the long run, since they are securely fixed in the region of the cell poles on the cooling plate and are prevented by the support plate radial movements of the individual cells. Due to the free space between the bottom region of the individual cells and the housing bottom, thermal expansion of the individual cells is made possible without causing mechanical stresses between individual cells and other battery parts due to different thermal expansions and temperature levels of different parts (eg potting compound) or damaging the individual cells or other parts of the battery become.
