Description

TECHNICAL FIELD

[0001] The utility model relates to energy storage device technical field, concretely relates to a super capacitor module and power box. BACKGROUND

[0002] Super capacitor is applied to wind power generation, automobile power recovery compensation, locomotive traction, starting power and many other fields because its material is mostly carbon and does not pollute the environment, and has the advantages of long service life of hundreds of thousands of times, fast charging and discharging speed and high efficiency. For automobile starting power product, it is usually of box type structure, and the super capacitor module is arranged in the box body. The basic structure can refer to the automobile starting power disclosed in the Chinese utility model patent application with the authorized announcement number CN216331872U. It constitutes a power box. For this kind of power box product, portability is required, and size, weight and cost are important evaluation indexes. Therefore, the super capacitor module configured in the power box should be as small as possible in size, as light as possible in weight and as low as possible in cost, so that the product will have competitiveness.

[0003] The basic structure of the super capacitor module can be seen from Figure 1 The super capacitor module comprises a cover plate 1, a bottom plate 2 and a plurality of super capacitor monomers 200. The upper and lower ends of each super capacitor monomer 200 are respectively provided with electrodes, one end being a positive electrode and the other end being a negative electrode. Each super capacitor monomer 200 is connected in series through a plurality of conductive rows. Both ends of the super capacitor monomer 200 are fixed with conductive rows. The conductive row is a copper sheet structure, which is fixed with the end electrode of the super capacitor monomer and forms a conductive connection. Each super capacitor monomer 200 and each conductive row are located between the cover plate 1 and the bottom plate 2. The cover plate 1 and the bottom plate 2 are both made of insulating material. The cover plate 1 and the bottom plate 2 are fixedly connected by a plurality of fixing components to fix the super capacitor monomers 200 together. The upper surface of the cover plate 1 is provided with a capacitor balancing control circuit board. The bottom plate 2 can be installed on the bottom wall of the box body of the power box. The fixing components connecting the cover plate 1 and the bottom plate 2 include long bolts 101, nuts 102 and support sleeves 103. The cover plate 1 and the bottom plate 2 are provided with bolt through holes for the long bolts 101 to pass through. The support sleeves 103 are clamped between the cover plate 1 and the bottom plate 2 to limit the distance between the cover plate 1 and the bottom plate 2. The long bolts 101 pass through the cover plate 1, the support sleeves 103 and the bottom plate 2 and are connected with the nuts 102, so as to fix the super capacitor monomers 200 as a whole.

[0004] However, for the fixing structure of the super capacitor module as described above, a plurality of long bolts and support sleeves are required. The long bolt is a metal part and is relatively heavy, which increases the weight of the super capacitor module and is not conducive to the portability of the power box. At the same time, the structure of using long bolts as fastening connecting pieces and supporting sleeves will also increase the manufacturing cost. UTILITY MODEL CONTENTS

[0041] The cover plate 1 and the bottom plate 2 are arranged in an up-down manner, and each super capacitor cell 200 and the conductive row are arranged between the cover plate 1 and the bottom plate 2. The cover plate 1 is provided with a connecting structure fixedly connected with the conductive row fixed at one end of the cover plate 1 adjacent to the super capacitor cell 200, and the bottom plate 2 is provided with a connecting structure fixedly connected with the conductive row fixed at one end of the bottom plate 2 adjacent to the super capacitor cell 200. The upper end of the super capacitor cell 200 is the end adjacent to the cover plate 1, the connecting conductive row 7 fixedly connected with the electrode at the upper end of the super capacitor cell 200 is fixedly connected with the cover plate 1, the lower end of the super capacitor cell 200 is the end adjacent to the bottom plate 2, and the connecting conductive row 7 fixedly connected with the electrode at the lower end of the super capacitor cell 200 is fixedly connected with the bottom plate 2. The cover plate 1 and the bottom plate 2 are fixedly connected through the respective connecting conductive rows 7 to fix the super capacitor cells 200 together.

[0042] Since each super capacitor cell 200 is connected in series and parallel through the connecting conductive row 7, and the connecting conductive row 7 is fixedly connected with the super capacitor cell 200, the cover plate 1 and the bottom plate 2 are fixedly connected through the connecting conductive row 7, the cover plate 1 fixes the connecting conductive rows 7 at the upper end together, the bottom plate 2 fixes the connecting conductive rows 7 at the lower end together, and the super capacitor cells 200 are fixed together by fixing the connecting conductive rows 7 together. Such a fixing structure is relatively simple, the cover plate 1 and the bottom plate 2 are fixed by the conductive row nearby, and long bolts and other parts are not needed, which is conducive to reducing the weight of the super capacitor module. In the embodiment, all the connecting conductive rows 7 at the upper end of the super capacitor cell 200 are fixed with the cover plate 1, and all the connecting conductive rows 7 at the lower end of the super capacitor cell 200 are fixed with the bottom plate 2, so as to enhance the stability. In other embodiments, a part of the connecting conductive rows can not be fixed with the cover plate or the bottom plate. In the embodiment, the cover plate and the bottom plate are fixedly connected with the connecting conductive row, but not fixedly connected with the positive electrode lead-out conductive row and the negative electrode lead-out conductive row. In other embodiments, the positive electrode lead-out conductive row and the negative electrode lead-out conductive row can be fixedly connected with the bottom plate and the cover plate respectively.

[0043] In the embodiment, the cover plate 1 and the bottom plate 2 are fixedly connected to the respective connecting conductive rows 7 in a clamping manner, and the connecting structure on the cover plate 1 and the connecting structure on the bottom plate 2 are clamped with the connecting conductive row 7. Figure 4 Figure 5 Figure 6 The connecting structure on the cover plate 1 and the connecting structure on the bottom plate 2 are buckles 8, and the respective connecting conductive rows 7 are provided with clamping matching parts for clamping the buckles 8, so that the cover plate 1 and the bottom plate 2 are clamped and fixed with the respective connecting conductive rows 7. The clamping structure is used for fixing, which is convenient for assembly operation, the buckle 8 can be a plastic part to reduce the weight of the module and save cost. In other embodiments, bolt holes can be provided on the cover plate and the bottom plate, the bolt holes are provided with bolts, threaded holes are provided on the conductive row, and the bolts constitute the connecting structure to fixedly connect the cover plate and the bottom plate to the respective conductive rows through the bolts.​​

[0044] The buckle 8 on the cover plate 1 is located on the lower side of the cover plate 1, and the buckle 8 on the base plate 2 is located on the upper side of the base plate 2. The buckle 8 includes a fixing part 81 for fixing to the cover plate 1 or the base plate 2 and a snap-fit ​​part 82 for snap-fitting with the connecting conductive busbar 7. The snap-fit ​​part 82 has two elastically deformable hooks. The connecting conductive busbar 7 is provided with a snap-fit ​​hole 71, which constitutes the snap-fit ​​part. The snap-fit ​​part 82 of the buckle 8 passes through the snap-fit ​​hole 71 from one side of the conductive busbar and snaps into the other side of the conductive busbar. The hooks of the snap-fit ​​part 82 retract when they enter the snap-fit ​​hole 71, and deform and stop on the corresponding side of the connecting conductive busbar 7 after they exit the snap-fit ​​hole 71. The snap-fit ​​is formed by the snap-fit ​​hole 71 and the buckle 8, which has a simple structure and reliable snap-fit. In other embodiments, the buckle may also have two hooks that are arranged opposite each other, and the two hooks are respectively snapped into the two edges in the width direction of the conductive busbar.

[0045] The fixing part 81 of the buckle 8 has a columnar structure. The end face of the fixing part 81 facing away from the snap-fit ​​part 82 is bonded and fixed to the corresponding side of the cover plate 1 or the base plate 2. The structure is simple and easy to manufacture. In other embodiments, a buckle fixing hole can be provided on the cover plate or the base plate to make the fixing part of the buckle longer, and the fixing part can be heat-riveted by passing through one end of the cover plate or the base plate. In other embodiments, the buckle can also be integrally formed with the cover plate or the base plate.

[0046] The snap-fit ​​hole 71 on the conductive busbar 7 has a clearance groove 711 at its opening to avoid the fixing part 81 of the buckle 8. The opening of the snap-fit ​​hole 71 with the clearance groove 711 is the opening through which the buckle 8 passes. The buckle 8 enters from one side of the snap-fit ​​hole 71 and exits from the other side. The fixing part 81 of the buckle 8 can enter into the clearance groove 711 at the opening of the snap-fit ​​hole 71 and abut against the bottom of the clearance groove 711, so that the cover plate 1 and the base plate 2 can fit against the corresponding conductive busbar, which is beneficial for reliable fixation and can reduce the vertical height of the module. In other embodiments, the clearance groove may not be provided, and a small gap may be formed between the cover plate, the base plate and the corresponding conductive busbar due to the separation of the fixing part of the buckle.

[0047] The clearance groove 711 provided at the opening of the snap-fit ​​hole 71 is adapted to the fixing part 81 of the buckle 8. The clearance groove 711 has a limiting groove wall that limits the fixing part 81 of the buckle 8 in the radial direction of the snap-fit ​​hole 71, so as to ensure that the cover plate 1 and the bottom plate 2 are in a vertical position, thereby enhancing stability. In other embodiments, radial limiting can be achieved without relying on the cooperation between the clearance groove and the fixing part of the buckle, and the buckle can be radially limited by the part of the snap-fit ​​hole other than the clearance groove.

[0048] The insulating cover plate 1 and the bottom plate 2 can be made of epoxy resin, nylon or nylon + glass fiber. The upper side of the cover plate 1 is provided with a capacitor equalization control circuit board 3, and the capacitor equalization control circuit board 3 is provided with components for monitoring the capacitor voltage and temperature. The corresponding components are connected to each connection conductive row 7 through a capacitor voltage and temperature collection wire harness 4. The end of each wire of the capacitor voltage and temperature collection wire harness 4 for connecting each connection conductive row 7 is provided with a collection wire harness terminal 41. Each connection conductive row 7 is provided with a terminal connection hole 72 for fixedly connecting the collection wire harness terminal 41. The upper side collection wire harness terminal 41 extends between the upper side connection conductive row 7 and the cover plate 1, and the lower side collection wire harness terminal 41 extends between the lower side connection conductive row 7 and the bottom plate 2. The collection wire harness terminal 41 is an OT terminal, which can be fixed at the terminal connection hole 72 by a bolt. The side hole of the terminal connection hole 72 of the connection conductive row 7 facing away from the super capacitor cell 200 is provided with a clearance groove, which is an open groove. The clearance groove is adapted to the collection wire harness terminal 41 to extend into, so as to avoid the collection wire harness terminal 41 occupying additional space in the up-down direction. In other embodiments, the collection wire harness terminal can also be welded and fixed with the conductive row without the terminal connection hole.

[0049] The terminal connection hole 72 and the clamping fitting hole 71 are symmetrically arranged in the width direction of the conductive row, that is, the clearance groove at the hole of the terminal connection hole 72 and the clearance groove 711 at the hole of the clamping fitting hole 71 have the same structure, both of which are open grooves, and the opening of the open groove penetrates through the edge in the width direction of the connection conductive row 7. By arranging the terminal connection hole 72 and the clamping fitting hole 71 as a symmetrical structure, the connection conductive row 7 and the super capacitor cell 200 can be fixed without distinguishing the direction, which is convenient for operation. In other embodiments, the terminal connection hole and the clamping fitting hole can also be arranged as different structures. The clamping fitting hole is arranged as a counterbore, and the large-diameter hole section of the counterbore constitutes the clearance groove.

[0050] The clamping fitting hole 71 of the connection conductive row 7 is the part of the connection conductive row 7 for fixedly connecting the bottom plate 2 or the cover plate 1, which corresponds to the position of the gap between the adjacent two super capacitor cells 200. The terminal connection hole 72 and the clamping fitting hole 71 are arranged at the middle position in the length direction of the connection conductive row 7, and both of them correspond to the gap between the adjacent two super capacitor cells 200. Since the super capacitor cell 200 is a cylinder, a gap is formed between the outer circumferential surfaces of the adjacent two super capacitor cells 200, so that the part of the connection conductive row 7 for fixedly connecting the cover plate 1 or the bottom plate 2 corresponds to the gap, which facilitates the use of the space at the gap to arrange the connection structure, and avoids increasing the size of the connection conductive row 7. In other embodiments, when the size of the connection conductive row is large enough, the clamping fitting hole can also be arranged at the end of the conductive row in the length direction.

[0051] The electrode 201 of the supercapacitor cell 200 is a pole, the conductive row is provided with a pole fixing hole 73, the pole is matched with the pole fixing hole 73, the pole fixing hole 73 penetrates along the thickness direction of the conductive row, the electrode 201 extends into the pole fixing hole 73, and the conductive row is fixed to the electrode 201 at the pole fixing hole 73 through welding. The two ends in the length direction of the conductive row are respectively provided with the pole fixing hole 73 for the electrode 201 of the supercapacitor cell 200 to extend into. The pole fixing hole 73 is matched with the electrode 201 for welding, so that the height in the up-down direction of the module can be reduced. In other embodiments, the electrode can also be a threaded stud, and the conductive row is fixed to the electrode through a nut.

[0052] In order to further reduce the height of the module, the cover plate 1 and the bottom plate 2 are respectively provided with conductive row avoiding grooves 11 for the conductive row to enter, and the conductive row avoiding grooves 11 are matched with the conductive row to provide the conductive row with a space in the thickness direction of the conductive row. Figure 4 The cover plate 1 is taken as an example, the lower side of the cover plate 1 is provided with the conductive row avoiding grooves 11, and each of the upper conductive rows fixed with the upper end electrode 201 of the supercapacitor cell 200 corresponds to one conductive row avoiding groove 11. When the cover plate 1 is installed, the conductive row can enter the conductive row avoiding groove 11, and the thickness dimension of the cover plate 1 in the up-down direction is used to provide the arrangement space of the conductive row in the thickness direction of the conductive row, so that the height of the module is reduced. Correspondingly, the buckle 8 is fixed at the groove bottom of the conductive row avoiding groove 11, so as to adapt to the position of the clamping matching hole 71 on the connecting conductive row 7. In order to facilitate the arrangement of the capacitor voltage temperature collection wire harness 4, the cover plate 1 is further provided with a wiring groove 12, the wiring groove 12 is connected with the corresponding conductive row avoiding groove 11, and the corresponding wire harness can be placed in the wiring groove 12. In order to avoid the fixing bolt of the collection wire harness terminal 41 and the connecting conductive row 7, the position corresponding to the terminal connecting hole 72 on the connecting conductive row 7 of the conductive row avoiding groove 11 is provided with a terminal avoiding groove 13, and the terminal avoiding groove 13 is located at the groove bottom of the conductive row avoiding groove 11, so as to avoid the head of the corresponding fixing bolt.

[0053] The bottom plate 2 is the same as the cover plate 1, the bottom plate 2 is provided with the conductive row avoiding groove for the lower conductive row to enter, the wiring groove for arranging the corresponding wire harness, and the terminal avoiding groove for avoiding the fixing bolt of the corresponding collection wire harness terminal.

[0054] Moreover, the cover plate 1 and the bottom plate 2 are provided with the avoiding grooves corresponding to the conductive row, so that the conductive row can be limited in the horizontal direction, the vertical space is saved, and the insulation effect is achieved. The wiring groove 12 provides a wiring path for the low-voltage wire harness, saves the vertical space, protects the low-voltage wire harness, and prevents the wire harness from being worn by other metal parts. The terminal avoiding groove 13 can insulate and protect and limit the collection wire harness terminal 41. The cover plate 1 and the bottom plate 2 ensure a certain structural strength and play an insulating protection role.

[0055] Compared with a module using a long bolt fixing structure, the super capacitor module reduces the weight, size and cost of the module, is simple and reliable in structure, and is more suitable for application in the field of portable starting power supply.
