(16) The battery module 10 comprises a multiplicity of battery cells 100.sub.1, 100.sub.2, 100.sub.3, for example two, three, four or more battery cells. As shown by way of example in FIG. 1, the battery cells 100.sub.1, 100.sub.2, 100.sub.3 are oriented in a first direction in space (x) such that the longitudinal sides thereof, which are oriented in a second direction in space (y) perpendicular to the first direction in space (x), run parallel to one another. A third direction in space (z) which is perpendicular to the first direction in space (x) and second direction in space (y) denotes the vertical direction of the battery cells 100.sub.1, 100.sub.2, 100.sub.3 during use according to the specifications.

(17) The battery cells 100.sub.1, 100.sub.2, 100.sub.3 can be prismatic, for example cuboidal, and can each comprise a cell housing and a cell cover with in each case two electric cell terminals 150.sub.1, 155.sub.1, 150.sub.2, 155.sub.2, 150.sub.3, 155.sub.3, for example made of aluminum or copper. For the electrical connection, the electric cell terminals can, for example, each comprise a threaded hole. For the electrical connection of the battery cells 100.sub.1, 100.sub.2, 100.sub.3 to form a battery module, use can be made of connecting pieces, for example cell connectors, for example made of aluminum or copper, which electrically connect the cell terminals of the battery cells 100.sub.1, 100.sub.2, 100.sub.3 to one another in accordance with the particular requirement. For the production of the battery module, the connecting pieces can be welded, for example according to the spatial orientation of the battery cells 100.sub.1, 100.sub.2, 100.sub.3, to the cell terminals, for example by means of a laser.

(18) The battery cells 100.sub.1, 100.sub.2, 100.sub.3 can be designed as primary cells or primary elements, which are not rechargeable, or as secondary cells, which are rechargeable. The secondary cells can be designed, for example, as lithium-ion storage batteries (lithium storage batteries, lithium-ion storage batteries, Li-ion storage batteries, Li-ion secondary batteries) or lithium-polymer storage batteries (LiPoly storage batteries, LiPo storage batteries). The battery cells 100.sub.1, 100.sub.2, 100.sub.3 can be designed with an electrode roll (jelly roll, JR, swiss roll), for example in the form of a lithium-ion storage battery with an electrode roll (JR-Li-ion storage battery). The battery cells 100.sub.1, 100.sub.2, 100.sub.3 can be designed as a pouch cell.

Furthermore, a protective envelope can enclose the electrode roll or the electrode rolls and/or the pouch or the pouches. The protective envelope can comprise a durable (impact resistant, bulletproof, shot proof, bombardment proof, ballistic, anti-ballistic) material, for example a ballistic fabric, such as a ballistic polyamide fabric (ballistic nylon fabric, ballistic nylon). The electrode rolls can therefore be protected against damage from the outside, for example in the event of an accident, and/or in the event of thermal runaway of an electrode roll, which can exert considerable forces on adjacent battery cells.

(19) The battery module 10 furthermore comprises a first carrier device 200.sub.1 comprising a first receiving region 202.sub.1, and a second carrier device 200.sub.2, which is arranged opposite the first carrier device 200.sub.1, comprising a second receiving region 202.sub.2 for carrying the battery cells 100.sub.1, 100.sub.2, 100.sub.3. The carrier devices 200.sub.1, 200.sub.2 are preferably of identical design. The carrier devices 200.sub.1, 200.sub.2 can be designed as side parts. As shown by way of example in FIG. 1, the carrier devices 200.sub.1, 200.sub.2 and/or the receiving regions 202.sub.1, 202.sub.2 can be of U-shaped design such that they enclose the battery cells 100.sub.1, 100.sub.2, 100.sub.3 at the cell bases, for example by means of a base-side projection or limb, and at the cell covers, for example by means of a cover-side projection or limb. The bottom-side projection and/or the bottom-side projections can be toothed, for example in a ratio of 50:50, such that the quantity of material and therefore the weight can be reduced. The carrier devices 200.sub.1, 200.sub.2 can be designed as a profile, for example U-shaped profile, extruded profile or endless profile. The length of the carrier devices 200.sub.1, 200.sub.2 along the first direction in space (x) can be adapted to the length of the battery cells 100.sub.1, 100.sub.2, 100.sub.3 in the first direction in space (x) such that the module carrier is scalable with respect to the number of battery cells 100.sub.1, 100.sub.2, 100.sub.3. The carrier devices 200.sub.1, 200.sub.2 can be formed from plastic or metal, for example aluminum or an aluminum alloy. The carrier devices 200.sub.1, 200.sub.2 are arranged in such a manner that the receiving regions 202.sub.1, 202.sub.2 are arranged opposite each other and the battery cells 100.sub.1, 100.sub.2, 100.sub.3 are enclosed along the first direction in space (x) at least partially in the manner of a clamp. The carrier devices 200.sub.1, 200.sub.2 can be designed in such a manner that they are reliably spaced apart from the cell terminals 150.sub.1, 150.sub.2, 150.sub.3, 155.sub.1, 155.sub.2, 155.sub.3 and/or the cell terminals 150.sub.1, 150.sub.2, 150.sub.3, 155.sub.1, 155.sub.2, 155.sub.3 are reliably concealed.

(20) The battery module 10 furthermore comprises a first connecting device 300.sub.1 and a second connecting device 300.sub.2, which is arranged opposite the first connecting device 300.sub.1, for connecting the carrier devices 200.sub.1, 200.sub.2 to each other. The connecting devices 300.sub.1, 300.sub.2 are preferably of identical design. The connecting devices 300.sub.1, 300.sub.2 can be designed as end plates or terminating plates. The connecting devices 300.sub.1, 300.sub.2 can be formed from plastic or metal, for example aluminum or an aluminum alloy.

(21) The connecting devices 300.sub.1, 300.sub.2 are connected to the carrier devices 200.sub.1, 200.sub.2 in such a manner that the multiplicity of battery cells 100.sub.1, 100.sub.2, 100.sub.3 are fixed and/or braced in the module carrier. For this purpose, as shown by way of example in FIG. 1, the carrier devices 200.sub.1, 200.sub.2 and the connecting devices 300.sub.1, 300.sub.2 can comprise holes 210.sub.1, 220.sub.1, 210.sub.2, 220.sub.2 or 310.sub.2, 320.sub.2, 330.sub.2, 340.sub.2. The holes 210.sub.1, 220.sub.1, 210.sub.2, 220.sub.2 of the carrier devices 200.sub.1, 200.sub.2 may be in the form of threaded holes. The connecting devices 300.sub.1, 300.sub.2 can be screwed to the carrier devices 200.sub.1, 200.sub.2, for example by screws 410.sub.2, 420.sub.2, 430.sub.2, 440.sub.2, such as head screws, flat head screws or countersunk head screws, threaded rods, threaded bolts and/or nuts. Alternatively, the connecting devices 300.sub.1, 300.sub.2 can be riveted to the carrier devices 200.sub.1, 200.sub.2 by means of rivets. Furthermore, the connecting devices 300.sub.1, 300.sub.2 can be welded or adhesively bonded to the carrier devices 200.sub.1, 200.sub.2.

(22) The production of the battery module 10 can comprise cutting the carrier devices 200.sub.1, 200.sub.2 to size depending on the number of battery cells 100.sub.1, 100.sub.2, 100.sub.3 and/or the dimensions thereof. The production comprises inserting the battery cells 100.sub.1, 100.sub.2, 100.sub.3 into or between the carrier devices 200.sub.1, 200.sub.2 and connecting the carrier devices 200.sub.1, 200.sub.2 by means of the first connecting devices 300.sub.1. These steps can be carried out in a different sequence. The production furthermore comprises connecting the carrier devices 200.sub.1, 200.sub.2 by means of the second connecting devices 300.sub.2.

The carrier devices 200.sub.1, 200.sub.2 are illustrated in shortened form in comparison to FIG. 1. The lengths of said carrier devices in the first direction in space (x) can be adapted to the dimensions and the number of battery cells, and therefore the module carrier 20 is scalable with respect to the number of battery cells.

(25) FIG. 3 shows a schematic perspective exploded view of a module carrier 30 according to another embodiment of the invention.

(26) The module carrier 30 corresponds to the module carrier described with respect to FIG. 1. The base-side limbs of the carrier devices 200.sub.1, 200.sub.2 are designed to be longer than the cover-side limbs of the carrier devices 200.sub.1, 200.sub.2, and therefore the cell bases of the battery cells are enclosed and protected. The carrier devices 200.sub.1, 200.sub.2 and the connecting devices 300.sub.1, 300.sub.2 here can comprise further holes for fastening purposes in the region of the extended, base-side limbs.

(27) FIG. 4 shows a schematic perspective exploded view of a module carrier 40 according to another embodiment of the invention.

The baseplate 500 can comprise holes 510, 520. The holes 510, 520 in the baseplate 500 can be designed, as described above, as threaded holes. The connecting devices 300.sub.1, 300.sub.2 can comprise further holes 360.sub.1, 350.sub.2, 360.sub.2 such that said connecting devices can be screwed to the baseplate 500, for example, by means of screws 450.sub.2, 460.sub.2, threaded rods, threaded bolts and/or nuts.

(29) FIG. 5 shows a schematic perspective exploded view of a module carrier 50 according to another embodiment of the invention.

(30) The module carrier 50 corresponds to the module carrier described with respect to FIG. 1 and is designed for controlling the temperature of the battery cells. For this purpose, the first carrier device 200.sub.1 comprises a channel 270.sub.1, which is substantially formed along the first direction in space (x), for receiving a temperature control medium. The temperature control medium can comprise a fluid, for example a liquid, such as alcohol, for example propane-1,2,3-triol (glycerol, glycerin), oil or water or a liquid mixture. As shown by way of example in FIG. 5, the channel 270.sub.1 can have a round cross section. Alternatively, the channel 270.sub.1 can have an oval, rectangular, rounded rectangular or square cross section. The channel 270.sub.1 can be of rectilinear or wavy design, such as sinusoidal design, along the first direction in space (x). The first connecting device 300.sub.1 comprises a connection channel 370.sub.1, which is connectable to the channel 270.sub.1 and comprises a connector 372.sub.1 for the inflow or outflow of the temperature control medium, and the second connecting device 300.sub.2 comprises a connection channel, which is connectable to the first channel 270.sub.1 and comprises a connector 372.sub.2 for the outflow or inflow of the temperature control medium. The connection channels can be formed in the interior of the connecting devices 300.sub.1, 300.sub.2 and can each comprise an opening which is adapted with respect to cross section, size and/or position to the channel 270.sub.1 such that the connection channels are connectable to the channel 270.sub.1. As shown by way of example in FIG. 5, the connectors 372.sub.1, 372.sub.2 can be arranged on the connecting devices 300.sub.1, 300.sub.2, for example along the first direction in space (x). The connectors 372.sub.1, 372.sub.2 can be designed, for example, as connecting branches, threaded connecting branches or olives. The connectors 372.sub.1, 372.sub.2 can be connected to a temperature control system. The battery cells can therefore be temperature-controlled by means of the temperature control medium flowing through the first channel 270.sub.1. The module carrier 50 can furthermore comprise sealing devices (not shown), for example seals, such as sealing rings, sealing washers or sealing plates, or a sealing compound, for the sealing, for example pressure-proof or hydraulically tight sealing, of transitions between the channels.

(36) However, in this embodiment, the first connecting device 300.sub.1 comprises a return channel 390.sub.1, which is connectable to the channel 270.sub.1 and to the further channel 275.sub.1, for the return of the temperature control medium which, first of all, for example, coming from the second connecting device 300.sub.2 flows via the channel 270.sub.1 through the first carrier device 200.sub.1 and subsequently, now coming from the first connecting device 300.sub.1, flows once again through the first carrier device 200.sub.1 via the further channel 275.sub.1. As shown by way of example in FIG. 7, the return channel 390.sub.1 can be designed as a depression or trench. Alternatively, the return channel 390.sub.1 can be formed in the interior of the first connecting device 300.sub.1 and can comprise two openings which are spaced apart from each other.

(37) The second connecting device 300.sub.2 comprises a further connection channel, which is connectable to the second channel 275.sub.1 and comprises a further connector 376.sub.2 for the outflow or inflow of the temperature control medium. As shown by way of example in FIG. 7, the connectors 372.sub.2, 376.sub.2 can be arranged on the second connecting device 300.sub.2, for example along the first direction in space (x).

(39) FIG. 8 shows a schematic perspective exploded view of a module carrier 80 according to another embodiment of the invention.

(40) The module carrier 80 corresponds to the module carrier 70 described with respect to FIG. 7. As shown by way of example in FIG. 8, the connectors 372.sub.2, 376.sub.2, 282.sub.2, 386.sub.2 can be arranged on the second connecting device 300.sub.2 along the third direction in space (x), for example on the upper side. For this purpose, the connection channels 370.sub.1, 380.sub.1, 370.sub.2, 380.sub.2 run substantially along the third direction in space (z) in the connecting devices 300.sub.1, 300.sub.2.

(41) FIG. 9 shows a schematic perspective exploded view of a module carrier 90 according to another embodiment of the invention.

(42) The module carrier 90 is similar to the module carrier 70 described with respect to FIG. 7; the carrier devices 200.sub.1, 200.sub.2 in each case comprise two channels 270.sub.1, 275.sub.1, 270.sub.2, 275.sub.2 for receiving the temperature control medium.

(43) However, in this embodiment, the first connecting device 300.sub.1 comprises a transfer channel 394.sub.1, which is connectable to the channels 270.sub.1, 270.sub.2 of the carrier device 200.sub.1, 200.sub.2, for the transfer of the temperature control medium which, for example, first of all, coming from the direction of the second connecting device 300.sub.2, flows via the channel 270.sub.1 through the first carrier device 200.sub.1 and subsequently, then coming from the first connecting device 300.sub.1, flows through the second carrier device 200.sub.2 via the channel 270.sub.2. As shown in FIG. 7, the transfer channel 394.sub.1 can be formed in the interior of the first connecting device 300.sub.1 and can comprise two openings which are spaced apart from each other. The temperature control of a battery cell which is arranged adjacent to the first connecting device 300.sub.1 can be improved by the transfer channel 394.sub.1.

(44) Accordingly, the first connecting device 300.sub.1 can comprise a further transfer channel 396.sub.1, which is connectable to the further channels 275.sub.1, 275.sub.2 of the carrier device 200.sub.1, 200.sub.2, for the transfer of the temperature control medium which, for example, first of all, coming from the direction of the second connecting device 300.sub.2, flows via the further channel 275.sub.1 through the first carrier device 200.sub.1 and subsequently, then coming from the first connecting device 300.sub.1, flows through the second carrier device 200.sub.2 via the further channel 275.sub.2.

(45) Depending on the design of the module carrier 90 on the part of the second connecting device 300.sub.2, for example when the second connecting device 300.sub.2, which is described with respect to FIG. 8, is used with four connectors 372.sub.2, 376.sub.2, 282.sub.2, 386.sub.2, the temperature control medium can flow through the transfer channels 294.sub.1, 296.sub.1 in different, opposite directions, and therefore the temperature control becomes more uniform.

(46) The module carrier 90 can furthermore comprise a first connection device 600.sub.1 which comprises a connection channel 670.sub.1, 675.sub.1, which is connectable to the channel 270.sub.1 and/or to the further channel 275.sub.1 of the first carrier device 200.sub.1, and a connector 672.sub.1, for the inflow or outflow of the temperature control medium.

The screws 410.sub.2, 420.sub.2 can be adapted with respect to the length thereof, and therefore the second connecting device 300.sub.2 can be screwed to the first carrier device 200.sub.1.

(47) In a corresponding manner, the module carrier 90 can comprise a second connection device 600.sub.2 which comprises a connection channel 670.sub.2, 675.sub.2, which is connectable to the channel 270.sub.2 and/or to a further channel 275.sub.2 of the second carrier device 200.sub.2, and a connector 672.sub.2, and also a receiving region 602.sub.2 and holes 610.sub.2, 620.sub.2, for the inflow or outflow of the temperature control medium.

The screws 410.sub.1, 420.sub.1 can be adapted with respect to the length thereof, and therefore the first connecting device 300.sub.1 can be screwed to the first carrier device 200.sub.1.

(53) The module carrier 94 furthermore comprises a first return device 700.sub.1 which comprises a return channel, which is connectable to the channel 270.sub.1 and to the further channel 275.sub.1 of the first carrier device 200.sub.1, for the return of the temperature control medium which, for example, first of all, coming from the first connection device 600.sub.1, flows via the channel 270.sub.1 through the first carrier device 200.sub.1 and subsequently, then coming from the first return device 700.sub.1, once again flows through the first carrier device 200.sub.1 via the further channel 275.sub.1. The return channel can be formed in the interior of the first return device 700.sub.1 and can comprise two openings which are spaced apart from each other. Alternatively, the return channel can be designed as a depression or trench. The first return device 700.sub.1 is arranged between the first carrier device 200.sub.1 and the second connecting device 300.sub.2 such that the second connecting device 300.sub.2, which is described with respect to FIG. 1 and does not comprise any channels and/or connections, can be used.

The length of the first carrier device 200.sub.1 in the first direction in space (x) can be shortened by the length of the first return device 700.sub.1. The screws 410.sub.2, 420.sub.2 can be adapted in respect of the length thereof, and therefore the second connecting device 300.sub.2 can be screwed to the first carrier device 200.sub.1.

(56) The module carrier 20 corresponds to the module carrier described with respect to FIG. 1, and furthermore comprises fastening devices 205.sub.1, 305.sub.1, for example fastening holes or threaded holes for fastening the module carrier 20, and therefore the module carrier 20 can be fastened, for example by means of screws, in or to a battery pack, a battery, a battery system or a vehicle. As shown by way of example in FIG. 12, the fastening devices 205.sub.1, 305.sub.1 can be arranged at or on the carrier devices 200.sub.1, 200.sub.2 and/or connecting devices 300.sub.1, 300.sub.2. The fastening devices 205.sub.1, 305.sub.1 are preferably arranged in a grid, and therefore the module carrier 20 is scalable with respect to the number of battery cells 100.sub.1, 100.sub.2, 100.sub.3. The fastening devices 205.sub.1, 305.sub.1 are preferably spaced apart from the channels for the temperature control medium in such a manner that damage to the channels, for example by screws which are not adapted in respect of diameter, length and/or thread properties, such as type of thread or thread pitch, to fastening devices 205.sub.1, 305.sub.1, is reliably prevented.
