Therefore, the description proposed herein is just a preferable example for the purpose of illustrations only, not intended to limit the scope of the disclosure, so it should be understood that other equivalents and modifications could be made thereto without departing from the spirit and scope of the disclosure.

Mode for Disclosure

(12) A frame for secondary batteries according to the present disclosure is used to manufacture a battery module by laminating and packaging a plurality of secondary batteries, and can hold secondary batteries to be prevented from moving and guide the assembling of secondary batteries.

(13) FIG. 1 is a schematic perspective view of the configuration of a frame for secondary batteries 1000 according to one embodiment of the present disclosure. FIG. 2 is a right side view of the configuration of FIG. 1. However, in FIG. 1, just for convenience of description, some portion of an upper cooling plate 110 is shown to be cut off.

(14) With reference to FIG. 1 and FIG. 2, a frame for secondary batteries 1000 according to the present disclosure comprises an upper cooling plate 110, a lower cooling plate 120 and a main frame 200, and a support member 300.

(15) The upper cooling plate 110 is configured to have a large plate form and arranged to lie for the larger surface thereof to face up and down. Particularly, an upper cooling plate 110 can be configured to a rectangular plate form.

(16) The lower cooling plate 120 is configured to have a large plate form like the upper cooling plate 110, and can be formed in a shape to correspond to the shape of the upper cooling plate 110, for example, the same shape as that of the upper cooling plate 110. Particularly, a lower cooling plate 120 can be arranged below an upper cooling plate 110, so that the larger surface of the former can be faced mutually with the larger surface of the latter. Here, the lower cooling plate 120 can be arranged to be spaced apart by a predetermined distance from the upper cooling plate 110. Furthermore, a lower cooling plate 120 can be arranged to be parallel in the horizontal direction to an upper cooling plate 110.

(17) The upper cooling plate 110 and the lower cooling plate 120 can respectively be made of thermally conductive material allowing heat exchange with secondary batteries placed above and below. Particularly, such two cooling plates can be made of aluminum material which is highly thermally conductive, easy to mold and lightweight. However, the present disclosure is not limited to cooling plates with the above-mentioned materials, and they can be made of various materials such as metals other than aluminum.

(18) The main frame 200 can comprise four sides to encompass the outer peripheral portions of an upper cooling plate 110 and a lower cooling plate 120. In other words, as shown in FIG. 1, the main frame 200 can form a rectangular ring with the center being empty when viewed downward from the above. In an empty space in a main frame 200, an upper cooling plate 110 can be exposed upward, and a lower cooling plate 120 can be exposed downward.

(19) The main frame 200 can be manufactured by injection molding and the like, with an upper cooling plate 110 and a lower cooling plate 120 being interposed; however, the present disclosure is not limited to such manufacturing methods.

(20) The main frame 200 can be configured to mount pouch-type secondary batteries. Particularly, the main frame 200 can be configured to mount the outer peripheral portions of pouch-type secondary batteries. For example, as shown in FIG. 1, the main frame 200 can comprise four unit frames with both ends being connected to adjacent unit frames. Therefore, the four sides of rectangular pouch-type secondary batteries can be respectively mounted on the four unit frames.

(21) Here, pouch-type secondary batteries whose outer peripheral portions consist of four sides can be configured for all or some (for example, two sides) of the four sides to be mounted on a main frame 200.

(22) Preferably, two pouch-type secondary batteries can be mounted on the main frame 200. In other words, an upper cooling plate 110 and a lower cooling plate 120 can be arranged vertically in the center of the main frame 200; two pouch-type secondary batteries can be respectively arranged on an upper portion of an upper cooling plate 110 and on a lower portion of a lower cooling plate 120, in a main frame 200. Therefore, when two or more of frames for secondary batteries are stacked vertically, two secondary batteries can be stored in each frame for secondary batteries.

(23) Two or more of main frames 200 with the above configurations can be arranged to be stacked, and two or more of frames for secondary batteries can be stacked thereby. In other words, for the arrangement of a main frame 200 in FIG. 2, different main frames 200 can be stacked respectively above and below. When two or more of frames for secondary batteries are stacked in such manners, main frames 200 are arranged on an outer peripheral portion and cooling plates are arranged on an upper portion or a lower portion, with respect to secondary batteries.

(24) On the other hand, the main frame 200 can comprise a protrusion vertically protruding and insertion grooves corresponding to such protrusions to facilitate the stacking of two or more. For example, the main frame 200 can comprise a protrusion protruding upward, as indicated by P in FIG. 2, on an upper portion of at least one among four unit frames. And, as indicated by G in FIG. 2, the main frame 200 can be arranged to comprise insertion grooves having a concave shape corresponding to the shape of the protrusions, on a lower portion of the unit frame. Here, when frames for secondary batteries are stacked vertically, the protrusions of a main frame 200 placed below can be inserted into the insertion grooves of a main frame 200 placed above. According to such embodiments, protrusions and insertion grooves can guide the stacking of main frames 200 (i.e., frames for secondary batteries), facilitating the process of stacking and stably maintaining the structure formed by such stacking thereafter through the coupling strength of the protrusions and the insertion grooves.

(25) Preferably, the main frame 200 can comprise openings in the side surfaces, as indicated by O in FIG. 1 and FIG. 2. Here, openings are configured to penetrate through a main frame 200 horizontally, so that at least a portion of an empty space between an upper cooling plate 110 and a lower cooling plate 120 can be configured to be exposed outward. In other words, frames for secondary batteries for stacking according to the present disclosure, an empty space is formed between an upper cooling plate 110 and a lower cooling plate 120 to function as a channel, and the openings can expose such a channel formed between both cooling plates outward from the main frame 200. Therefore, air external to a main frame 200 can go into and out of a channel formed between two cooling plates via such openings.

(26) Here, it is preferable to form at least two of the openings O for one main frame 200. Then, at least one opening functions as an inlet and the other opening can function as an outlet. For example, as shown in FIG. 1, where a main frame 200 comprises four unit frames, which are respectively placed horizontally at front, rear, left and right locations, openings can be respectively formed on a left frame and a right frame. Here, an opening formed on a right frame can function as an inlet, and an opening formed on a left frame can function as an outlet. Therefore, as shown by a dotted arrow in FIG. 1, external air flown into the opening of a right unit frame flows along a channel between two cooling plates while performing heat exchange with secondary batteries via cooling plates. And, air which has performed such heat exchange with cooling plates can be discharged from a main frame 200 to the outside via the opening of a left frame.

(27) On the other hand, where the main frame 200 comprises two or more of openings, it is preferable to form at least two openings at opposite sides. For example, like the above embodiments, two openings can be respectively formed on a left frame and a right frame, or two openings can be respectively formed on a front frame and a rear frame. According to such embodiments, the inlet and the outlet of a channel are formed on opposite sides, so that the channel along which a fluid flows can be linear. Therefore, such configurations allow a fluid to go into and out of a main frame smoothly and quickly, and enhance cooling efficiency by flowing a fluid across the whole section of a channel formed between cooling plates.

(28) The support member 300 is arranged between two cooling plates to support both cooling plates. In other words, as shown in FIG. 2, the support member 300 is arranged between an empty space between an upper cooling plate 110 and a lower cooling plate 120, with the upper ends being in contact with lower portions of the upper cooling plates 110 and the lower ends being in contact with upper portions of the lower cooling plate 120. Therefore, the support member 300 can support an upper cooling plate 110 upward and a lower cooling plate 120 downward.

(29) Particularly, the support member 300 can be configured to keep the distance between an upper cooling plate 110 and a lower cooling plate 120 within a predetermined range. For example, the support member 300 can be configured to keep constant the distance between an upper cooling plate 110 and a lower cooling plate 120. According to such configurations in the present disclosure, it is possible to prevent the empty space between an upper cooling plate 110 and a lower cooling plate 120 from being narrowed so that a channel can be prevented from being constricted and blocked, ensuring a smooth flow of a fluid via a channel. Also, according to such configurations in the present disclosure, it is possible to prevent the distance between an upper cooling plate 110 and a lower cooling plate 120 from being widened, preventing cooling plates from exerting force upon secondary batteries and in turn disrupting the arrangement of secondary batteries assembled within a battery module.

(30) The support member 300 is structures to support an upper cooling plate 110 and a lower cooling plate 120, and are preferably made of materials having more than or equal to a predetermined mechanical rigidity. For example, the support member 300 can be made of metal material such as steel or in plastic material.

(31) Particularly, the support member 300 can be configured to be coupled with at least one of an upper cooling plate 110 and a lower cooling plate 120, so as to be fixed and unmovable therebetween.

(32) FIG. 3 is a cross-sectional view of a configuration of a support member 300 and cooling plates being coupled according to one embodiment of the present disclosure. For example, the configuration of FIG. 3 may be one form of a cross-section for the portion A in FIG. 1.

(33) With reference to FIG. 3, the support member 300 can be arranged to be coupled with an upper cooling plate 110 and a lower cooling plate 120, by coupling members 400. Here, coupling members with various shapes such as rivets and bolts to couple two parts mutually can be used for such coupling members 400. For example, as shown in FIG. 3, a support member 300 can be coupled with cooling plates by two of coupling members 400. Here, one coupling member 400 can be penetrated through an upper cooling plate 110 and inserted and coupled with an upper portion of a support member 300; the other coupling member 400 can be penetrated through a lower cooling plate 120 and inserted and coupled with a lower portion of a support member 300. According to such embodiments of the present disclosure, coupling members 400 can fix a support member 300 to be unmovable between an upper cooling plate 110 and a lower cooling plate 120, stably maintaining a channel to have a constant shape.

(34) FIG. 4 is a cross-sectional view of a configuration of a support member 300 and cooling plates being coupled according to another embodiment of the present disclosure. For example, the configuration of FIG. 4 may be the other form of a cross-section for the portion A in FIG. 1.

(35) With reference to FIG. 4, as indicated by B, a support member 300 can comprise a protrusion protruding upward and downward on the upper portions and/or on lower portions, and as indicated by H, holes can be formed on an upper cooling plate 110 and on a lower cooling plate 120. The protrusions on a support member 300 can be inserted and coupled with the holes on cooling plates, so that an upper cooling plate 110 and a lower cooling plate 120 can be coupled and fixed with a support member 300.

(36) As shown in many of the attached drawings, the support member 300 can be configured to have flat surfaces which are in contact with an upper cooling plate 110 and/or a lower cooling plate 120.

(37) In other words, a support member 300 comprise upper surfaces which are in contact with lower portions of an upper cooling plate 110 and lower surfaces which are in contact with upper portions of a lower cooling plate 120. Here, lower portions of an upper cooling plate 110 and upper portions of a lower cooling plate 120 can be formed to be flat; accordingly, a support member 300 can be configured to comprise upper surfaces and lower surfaces which are flat to correspond respectively to the lower surface of an upper cooling plate 110 and the upper surface of a lower cooling plate 120.

(38) According to such configurations in the present disclosure, a support member 300 come in surface contact with cooling plates to enlarge the contact area between a support member 300 and cooling plates. Therefore, a support member 300 can support enlarged portions for an upper cooling plate 110 and a lower cooling plate 120 more stably, improving fixing strength of a support member 300 and preventing the deformation of cooling plates more effectively.

(39) FIG. 5 to FIG. 7 are cross-sectional views of an configurations of a support member 300 and cooling plates being coupled according to still other embodiments of the present disclosure.

(40) With reference to FIG. 5 to FIG. 7, a support member 300 can comprise an upper support part 310 which is in contact with the lower surface of an upper cooling plate 110, a lower support part 320 which is in contact with the upper surface of a lower cooling plate 120, and a connecting part which connects upper support part 310 and lower support part 320 to each other.

(41) Here, an upper support part 310 and a lower support part 320 can be configured to comprise respectively flat upper surfaces and flat lower surfaces which are in contact with cooling plates. Particularly, an upper support part 310 and a lower support part 320 can respectively be configured in plates whose upper surfaces and lower surfaces are both flat.

(42) And a connecting part can support an upper support part 310 or a lower support part 320 by being placed therebetween while keeping the distance therebetween constant. Particularly, a connecting part can be formed to have a thickness (a length in the leftward/rightward direction in the drawing) less than that of an upper support part 310 or a lower support part 320.

(43) According to such configurations in the present disclosure, a support member 300 can come in stable contact with cooling plates through the enlarged contact area by an upper support part 310 and a lower support part 320 which have a larger thickness, while a connecting part having a thinner thickness can enlarge a cooling channel. Therefore, a support member 300 can enlarge a cooling channel stably.

(44) On the other hand, as shown in FIG. 5, a connecting part of a support member 300 can be located at the center of an upper support part 310 and a lower support part 320 horizontally (left and right in the drawing). In such configurations, a support member 300 can be formed to be I-shaped. According to such configurations in the present disclosure, a connecting part can allow an upper support part 310 and a lower support part 320 to support the whole portion relatively uniformly and stably.

(45) Still, a connecting part can be arranged at locations other than described. For example, as shown in FIG. 6, a connecting part can be arranged at left or right ends of an upper support part 310 and a lower support part 320. According to such configurations in the present disclosure, an upper support part 310 and a lower support part 320 can be coupled by more enlarged portions with which coupling members 400 such as rivets or bolts are coupled, thereby facilitating the process of coupling by such coupling members 400 and improving the coupling strength therefor.

(46) Also, a connecting part can be configured, so that portions coupled with an upper support part 310 and a lower support part 320 can be formed to have a thickness more than that of other portions. For example, as shown in FIG. 7, a connecting part can be configured, so that portions coupled with an upper support part 310 are formed to have a larger thickness, which decreases toward the center and increases thereafter, and portions coupled with a lower support part 320 are in turn formed to have a larger thickness again. Particularly, a support member 300 can be configured, so that upper portions and lower portions are formed to have the largest thickness, which decreases toward the center. According to such configurations in the present disclosure, a connecting part can be formed to have a smaller thickness around the center so as to enlarge a cooling channel, and a relatively larger thickness at the upper ends and lower ends to improve support strength for an upper support part 310 and a lower support part 320.

(47) Preferably, for a frame for secondary batteries for stacking according to the present disclosure, two or more of the support members 300 can be arranged, as shown in FIG. 1 and FIG. 2. And, such a plurality of support members 300 can be arranged to be spaced apart horizontally by a predetermined distance from each other in a space between two cooling plates. According to such configurations in the present disclosure, a plurality of support members 300 can stably support an upper cooling plate 110 and a lower cooling plate 120 across the whole portion thereof.

(48) Particularly, where three or more of support members 300 are arranged, it is preferable to arrange the distance respectively among support members 300 to be equal. According to such embodiments, an upper cooling plate 110 and a lower cooling plate 120 can be supported uniformly across the whole portion, and support member 300 can thus prevent the deformation of cooling plates more effectively.

(49) FIG. 8 is a schematic view of a configuration and layout of support member 300 according to one embodiment of the present disclosure. In FIG. 8, for convenience of description, support member 300 placed below upper cooling plates 110 will be indicated by dotted lines.

(50) With reference to FIG. 8, support member 300 can be formed to elongate in one direction. Here, support member 300 can be arranged for the longitudinal direction to be horizontal. Especially, a support member 300 can be arranged such that the longitudinal direction corresponds to a direction of a channel, i.e., the flow direction of a fluid. For example, in the arrangement in FIG. 8, where openings are respectively formed on a left side and on a right side of a main frame 200, a channel is formed leftward and rightward; support member 300 are then formed to elongate leftward and rightward such that the longitudinal direction corresponds to the direction of the channel. According to such embodiments, since support member 300 are formed to elongate in the flow direction of a fluid in a channel, the flow of a fluid will not be disrupted by support member 300 and furthermore be guided thereby to be flown more smoothly.

(51) Here, a plurality of such support members 300 formed to elongate in one direction can be comprised and be arranged to be perpendicular to the direction of a channel. For example, as shown in FIG. 8, where five of support members 300 are comprised in a frame for secondary batteries, such support member 300 can be respectively arranged to be perpendicular to the direction of a channel (i.e., extended frontward and reward) and spaced apart by a predetermined distance from each other.

(52) Also preferably, at least a portion of the support member 300 can be arranged on the outer peripheral portions, where a main frame 200 is placed, of cooling plates.

(53) For example, as indicated by C in FIG. 8, support member 300 can be arranged around the outer peripheral portions of an upper cooling plate 110 and a lower cooling plate 120, for example, where a main frame 200 is placed above and below. An upper cooling plate 110 and a lower cooling plate 120 are liable to being deformed around the outer peripheral portions, (i.e., the perimeter of cooling plates). According to such embodiments in the present disclosure, support member 300 can support the outer peripheral portions of such cooling plates, preventing the deformation of the outer peripheral portions of cooling plates and thus preventing a channel being blocked or other related issues.

(54) FIG. 9 is a schematic view of a configuration and layout of support member 300 according to another embodiment of the present disclosure. In FIG. 9, like FIG. 8, support member 300 will also be indicated by dotted lines. Hereinafter, description will be mainly given to aspects in FIG. 9 which are different from the arrangement in FIG. 8, and detailed description will be omitted for similar aspects to which the arrangement in FIG. 8 can be applied.

(55) With reference to FIG. 9, the support member 300 can be arranged to extend frontward/rearward and leftward/rightward, in a similar length for both directions, rather than elongate in one specific direction. Here, a plurality of the support members 300 can be arranged and spaced apart by a predetermined distance from each other across the whole portion of cooling plates to support the cooling plates. Particularly, a plurality of the support members 300 can be arranged not only in the direction perpendicular to a channel but also in the same direction as that of the channel. In other words, in the embodiment in FIG. 9, a plurality of support members 300 can be arranged not only to be spaced apart by a predetermined distance from each other in the direction perpendicular to a channel (frontward/rearward) but also to be spaced apart by a predetermined distance from each other in the same direction as that of the channel (leftward/rightward).

(56) FIG. 10 is a schematic view of a configuration and layout of support member 300 according to still another embodiment of the present disclosure. In FIG. 10, like FIG. 8, support member 300 will also be indicated by dotted lines, and description will be given to aspects different from the description already given.

(57) With reference to FIG. 10, an upper cooling plate 110 can comprise beads formed thereon, as indicated by D. Though not shown in FIG. 10, a lower cooling plate 120 can also comprise beads formed thereon corresponding to the bead shape of an upper cooling plate 110. Here, beads D can be configured to protrude toward the other cooling plate. In other words, beads formed on an upper cooling plate 110 can be formed to protrude downward, while beads formed on a lower cooling plate 120 can be formed to protrude upward. Here, beads formed on an upper cooling plate 110 can be configured to be in contact with beads formed on a lower cooling plate 120.

(58) On the other hand, as shown in FIG. 10, such beads can be formed to elongate in one direction, with the longitudinal direction being parallel to the direction of a channel.

(59) As shown in FIG. 10, a plurality of such beads can be formed on an upper cooling plate 110 and/or a lower cooling plate 120. Here, beads can be arranged to be spaced apart by a predetermined distance horizontally, particularly in the direction perpendicular to a channel.

(60) In such embodiments where beads are formed on an upper cooling plate 110 and/or on a lower cooling plate 120, support member 300 can be arranged on the portions where beads are not formed. Particularly, as shown in FIG. 10, support member 300 can be arranged to be spaced apart by a predetermined distance from the opposite ends of beads which are formed to elongate in one direction, in the direction toward a channel. According to such configurations in the present disclosure, support member 300 are arranged to be where beads are not formed, i.e., especially the outer peripheral portions of cooling plates are placed, supporting a space between cooling plates and thus preventing a channel therearound from being constricted.

(61) A battery module according to the present disclosure comprises a plurality of the frames, described above, for secondary batteries.

(62) FIG. 11 is a schematic view of a configuration of a battery module according to one embodiment of the present disclosure.

(63) With reference to FIG. 11, a battery module according to the present disclosure can comprise a plurality of pouch-type secondary batteries 10 along with a plurality of frames for secondary batteries 1000. Here, frames for secondary batteries 1000 can be stacked vertically, and inner spaces formed thereby can store pouch-type secondary batteries 10. Particularly, a battery module according to the present disclosure can be configured to store two pouch-type secondary batteries 10 for each frame for secondary batteries 1000.

(64) A battery pack according to the present disclosure can comprise one or more battery modules according to the present disclosure. And, such battery modules can comprise a plurality of the frames, described above, for secondary batteries according to the present disclosure. Also, a battery pack according to the present disclosure can further comprise, in addition to such battery modules, a case to store the same, and various devices to control charging/discharging thereof, for example, battery management system (BMS), a current sensor, a fuse, etc.

(65) Frames for secondary batteries according to the present disclosure can be applied to vehicles such as electric cars or hybrid cars. In other words, vehicles according to the present disclosure can comprise a battery pack according to the present disclosure, which can in turn comprise frames for secondary batteries.

(66) The present disclosure has been described in detail. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the disclosure, are given by way of illustration only, since various changes and modifications within the scope of the disclosure will become apparent to those skilled in the art from this detailed description.

(67) Also, while the present specification includes terms to indicate directions, such as upper, lower, above, below, left, right, front, rear and the like, such terms are just for convenience of description, and it will become apparent to those skilled in the art that such terms may be different depending on the locations of objects and observers.
