Referring to fig. 1 to 4, an energy storage power supply 100 according to an embodiment of the utility model includes a housing 10 and a plurality of battery cells 20. The housing 10 is provided with a receiving chamber 11. The inner wall 113 of the receiving chamber 11 is provided with a plurality of first fixtures 1111. The bottom wall of the first fixture 1111 is provided with a first through hole 1112. The plurality of battery cells 20 are in one-to-one correspondence with the plurality of first fixtures 1111. The battery cell 20 includes a body 21, a first pole 22, and a second pole 23. The first pole 22 and the second pole 23 are respectively provided at both ends of the body 21 in the longitudinal direction. One end of the body 21 is received in the first fixture 1111. The first post 22 is inserted through the first through hole 1112.

In the above-mentioned energy storage power supply 100, through setting up first mounting 1111 on the inner wall 113 that holds chamber 11, the one end holding of electric core 20 body 21 is in first mounting 1111 to electric core 20 can directly install on first mounting 1111, need not to assemble into the battery module earlier and load into casing 10 again, reduces the equipment process, reduce cost, can also reduce because of assembling the required part of battery module moreover, and then can promote the space utilization low and the reduction product size of product.

In one embodiment, at least a portion of the housing 10 of the stored energy power source 100 encloses a receiving cavity 11, the receiving cavity 11 for receiving the battery cell 20. The battery cell 20 may be a cylindrical battery cell. The battery cell 20 may be vertically disposed in the accommodating cavity 11, and its vertical direction corresponds to the length direction of the body 21. Correspondingly, the first fixing member 1111 may be disposed at the bottom of the receiving chamber 11 to fix the bottom end of the battery cell 20. It will be appreciated that the first fixture 1111 may also be provided at the top of the receiving chamber 11 to secure the top end of the battery cell 20. The first fixing member 1111 may be integrally formed with the housing 10 or may be connected to the bottom of the inner wall 113 of the receiving chamber 11 by other fixing means, so that the battery cell 20 is relatively fixed to the housing 10. The first pole 22 and the second pole 23 of the cell 20 are current interfaces when the cell 20 is powered or charged. The first pole 22 is a positive electrode, and the second pole 23 is a negative electrode, but the first pole 22 may be a negative electrode, and the second pole 23 may be a negative electrode. One of the first pole 22 and the second pole 23 is connected to the first fixture 1111. In the case that the first fixture 1111 is located at the bottom of the receiving chamber 11, and the first post 22 is a negative electrode, and the first post 22 is connected to the first fixture 1111, the second post 23 may be electrically connected to an external device through the housing 10 via the first through hole 1112 of the first fixture 1111. Thereby establishing a port for the stored energy power source 100 to externally energize or charge. The number of the first fixtures 1111 is identical to the number of the battery cells 20 so that all the battery cells 20 are fixed in one first fixture 1111, respectively. The first fixing member 1111 may be a circular groove, and the diameter of the first fixing member 1111 corresponds to the diameter of the battery cell 20, and the diameters may be equal to each other so that the battery cell 20 is fixed in the groove; the diameter of the first fixture 1111 may also be slightly smaller than the diameter of the cell 20 to increase the fixing strength by an interference fit. It is understood that the first fixture 1111 may be provided in a triangle, a polygon, or other irregular shape, and maintain the diameter of its maximum inscribed circle satisfying the above conditions. The diameter of the first through hole 1112 is not larger than the diameter of the first fixture 1111, thereby preventing the battery cell 20 from sliding off the first through hole 1112. Therefore, the size and weight of the energy storage power supply 100 can be reduced by reducing the number of structural members, so that the product structure and the assembly process are optimized, the volume energy density and the quality energy density of the product are improved, the cost is reduced, and the portable energy storage power supply is convenient to carry. In some embodiments, the first fixing member 1111 may be a fixing groove in interference fit with the battery cell 20, or may be a clamp, a clip, or the like to fix the battery cell 20.

In other embodiments, the battery cell 20 may be a square battery cell, and in the case that the battery cell 20 is a square battery cell, the shape of the first fixing member 1111 is also a corresponding square. In other implementations, the cells 20 may also be placed horizontally or in other orientations within the receiving chamber 11. In the case where the battery cells 20 are horizontally placed, the first fixing member 1111 may be provided on the front, rear, left or right inner walls of the receiving chamber 11 to fix the battery cells 20.

Referring to fig. 5, in some embodiments, a first bracket 111 is disposed on an inner wall of the accommodating cavity 11, and a plurality of first fixing members 1111 are disposed on the first bracket 111.

In this way, the structure of the housing 10 can be simplified.

Specifically, referring to fig. 5, in one embodiment, a first bracket 111 may be provided at the bottom of the receiving chamber 11, and a plurality of first fixtures 1111 may be provided on the first bracket 111. A plurality of first fixtures 1111 are assembled on the first bracket 111, so that the structure of the housing 10 can be simplified. The first brackets 111 may be welded to the housing 10, or may be detachably fixed to the housing 10 by bolts or the like, so as to replace the first brackets 111 having different numbers of the first fixing members 1111 as needed, thereby increasing the flexibility of the energy storage power source 100.

Referring to fig. 5, in some embodiments, the stored energy power source 100 includes a second bracket 112 positioned in the receiving chamber 11. The second bracket 112 is connected to the inner wall of the accommodating chamber 11. The second bracket 112 is provided with a plurality of second fixing members (not shown). The bottom wall of the second fixing member is provided with a second through hole 1121. The plurality of battery cells 20 are in one-to-one correspondence with the plurality of second fixing members. The other end of the body 21 is accommodated in the second fixing member. The second post 23 penetrates the second through hole 1121.

Thus, the fixing strength of the battery cell 20 is increased.

Specifically, referring to fig. 5, in one embodiment, in the case that the first fixing member 1111 fixes one end of the battery cell 20 and the first terminal 22 is inserted through the first through hole 1112 of the first fixing member 1111, the second bracket 112 may fix the other end of the battery cell 20. In the case that the first fixing member 1111 is disposed at the bottom of the receiving chamber 11, the second bracket 112 may be fixedly coupled to the top of the receiving chamber 11, so as to prevent the battery cell 20 from being bent or prevent the battery cell 20 from being thrown out when the energy storage power source 100 is disturbed by the outside such as vibration. The second fixing piece may be a circular groove, and the diameter of the second fixing piece corresponds to the diameter of the battery cell 20, and the diameters of the second fixing piece and the battery cell 20 may be equal to each other, so that the battery cell 20 is fixed in the groove; the diameter of the second fixing member may also be slightly smaller than the diameter of the battery cell 20, thereby increasing the fixing strength by interference fit. It will be appreciated that the second securing member may be provided in a triangular, polygonal or other irregular shape and maintain the diameter of its largest inscribed circle satisfying the above conditions. The diameter of the second through hole 1121 is not greater than the diameter of the second fixture, thereby preventing the battery cell 20 from sliding off the second through hole 1121. In the case that the diameter of the first through hole 1112 is smaller than that of the first fixing member 1111 and the diameter of the second through hole 1121 is smaller than that of the second fixing member, both ends of the battery cell 20 may simultaneously abut against the first fixing member 1111 of the first bracket 111 and the second fixing member of the second bracket 112, thereby further enhancing the fixing strength of the battery cell 20.

In some embodiments, the shape of the second fixing member corresponds to the cross-sectional shape of the battery cell 20, and may be square. In addition, in the case where the battery cells 20 are placed in the housing chamber 11 horizontally or in other directions, the first and second brackets 111 and 112 may be provided on the inner walls 113 in the corresponding directions in the housing chamber 11, and have an effect of fixing one ends of the battery cells 20, respectively. It will be appreciated that in other embodiments, the cells 20 may be positioned within the receiving cavity 11 at various angles and the positions of the components connected to the cells 20 adjusted accordingly. And will not be described in detail hereinafter.

Referring to fig. 2, in some embodiments, the first bracket 111 includes a plurality of struts 1115, and the struts 1115 are fixedly connected to the second bracket 112.

Thus, the fixing strength of the battery cell 20 is increased.

Specifically, referring to fig. 2, in one embodiment, the support posts 1115 on the first support 111 extend toward the second support 112 along the height direction of the stored energy power source 100 and are connected to the second support 112, the support posts 1115 may be provided with threaded holes, and the second support 112 may include a screw member for screwing into the threaded holes, so that the first support 111 is fixedly connected to the second support 112 through screw engagement, so as to clamp and fix the battery cells 20 at both ends of the battery cells 20. In addition, the first bracket 111 may further include a bottom plate, which is a structural body of the first bracket 111. The strut 1115 may be integrally formed with the base plate, or may be fixedly connected with the base plate by threaded connection or the like. In another embodiment, the strut 1115 may be fixedly connected to the second bracket 112 by a buckle, a latch, or the like.

Referring to fig. 6, in some embodiments, the first bracket 111 includes a perimeter wall 1113 that is coupled to the inner wall 113 of the receiving chamber 11. The enclosure wall 1113 encloses a receiving slot 1114. The receiving groove 1114 communicates with the plurality of first fixtures 1111.

Thus, the fixing strength of the battery cell 20 is increased.

Specifically, referring to fig. 6, in one embodiment, along the length direction of the body 21 of the cell 20, the first support 111 may have surrounding walls 1113 around the cell 20, where the height of the surrounding walls 1113 is smaller than the length of the cell 20. Along the length direction of the body 21 of the battery cell 20, the upper end and the lower end of the surrounding wall 1113 are provided with openings, and the first fixing member 1111 of the first bracket 111 closes the opening at one end. The surrounding wall 1113 and the first fastening member 1111 of the first bracket 111 enclose a receiving groove 1114, the receiving groove 1114 being enclosed within the receiving chamber 11.

Referring to fig. 6, in some embodiments, a fixing gel is injected into the accommodating groove 1114, and the fixing gel fixedly connects the battery cell 20 and the first bracket 111.

Thus, the safety of the battery cell 20 can be improved.

After the battery cell 20 is placed in the receiving groove 1114, the battery cell 20 blocks the first through hole 1112 of the first fixture 1111, thereby sealing the other sides of the receiving groove 1114 except the top end. With the top end of the holding tank 1114 open upward, a fixing gel is injected into the holding tank 1114. After the fixed gel is solidified, the first bracket 111, which is connected with the battery cell 20, can be placed in the accommodating cavity 11 in an inclined or horizontal posture. The stationary gel may have a certain viscous capability, thereby reducing the number of degrees of freedom of the cell 20. It will be appreciated that the stationary gel may not have viscous capability, thereby reducing two degrees of freedom of the cell 20. The fixing strength and the shock absorbing ability of the battery cell 20 can be further enhanced by the cooperation of the fixing gel with the first fixing member 1111.

Additionally, in some embodiments, the fixing gel may be a structural gel. The structural adhesive can bear larger load. By injecting structural glue into the receiving groove 1114, the impact resistance of the cell 20 can be enhanced. Under the condition that the shell 10 of the energy storage power supply 100 is damaged to directly impact the battery cell 20, the structural adhesive can bear a part of impact force, and meanwhile, the structural adhesive can transmit the impact force to the whole battery cell 20, so that impact damage is relieved. In addition, the structural adhesive has better corrosion resistance, and can prevent electrolyte from further leakage to corrode other battery cells 20 or other structural components when electrolyte leaks out of part of the battery cells 20 due to structural damage or electrolyte is sprayed out of an explosion-proof valve (not shown) of the battery cells 20 due to thermal runaway.

Referring to fig. 5 and 6, in some embodiments, the stored energy power source 100 includes a bus assembly 30. The bus assembly 30 includes a first bus bar 31 and a second bus bar 32. The first bus bar 31 connects the first poles 22 of at least two of the cells 20. The second bus bar 32 connects the second posts 23 of at least two of the cells 20.

In this manner, the battery cells 20 as a whole are advantageously powered by the powered device.

In particular, referring to fig. 5 and 6, in one embodiment, the stored energy power source 100 may increase the diversity of the output current through the bus assembly 30. The first terminal 22 of the cell 20 is connected to the first bus bar 31 through the first via 1112. The second pole 23 of the cell 20 may be directly connected to the bus bar. The first bus bar 31 may connect a portion of the first poles 22 of the battery cells 20, and the second bus bar 32 may connect a corresponding portion of the second poles 23 of the battery cells 20, such that the portion of the battery cells 20 outputs electrical energy outwardly or inputs electrical energy inwardly in parallel. The bus assembly 30 may include a plurality of first bus bars 31 and a plurality of second bus bars 32, and electrical energy may be externally output or internally input between the plurality of first bus bars 31 or between the plurality of second bus bars 32 in series or parallel. The bus assembly 30 may be copper, aluminum, nickel, or an alloy material. After the bus bar assembly 30 is fixed to the correct position by the working jig, the bus bar assembly 30 and the first or second posts 22 or 23 of the battery cell 20 may be welded together by laser welding. It will be appreciated that electrical connection of the buss assembly 30 to the poles of the cells 20 may also be accomplished by other means of connection such as twisting or crimping. In another embodiment, the energy storage power source 100 further includes a second bracket 112, and the second post 23 of the battery cell 20 may be connected to the second bus bar 32 through the second through hole 1121.

In addition, in yet another embodiment, the energy storage power source 100 may also collect the state information of each cell 20 through the collection component 40. The state information of the battery cells 20 may include information such as voltage, current, and temperature of each battery cell 20. The acquisition assembly 40 may include a first acquisition plate 41 and a second acquisition plate 42. The first collecting plate 41 is connected to the first bus bar 31. The second collector plate 42 is connected to the second bus bar 32. After the first bus bar 31 and the second bus bar 32 are welded, the first collecting plate 41 may be fixed to the corresponding position on the first bus bar 31 by screws, and the second collecting plate 42 may be fixed to the corresponding position on the second bus bar 32. After the fixing of the collecting assembly 40 is completed, the nickel strap of the first collecting plate 41 and the first busbar 31 can be connected in an electrical connection manner such as laser welding, so that the first collecting plate 41 and the first busbar 31 are electrically connected. At the same time, the second collecting plate 42 and the second bus bar 32 may be connected in the same manner.

Referring to fig. 5-8, in some embodiments, the stored energy power source 100 includes a cover 50. The outer side wall 12 of the housing 10 corresponding to the first fixing member 1111 is provided with a receiving groove 121. The first through hole 1112 penetrates the bottom wall of the accommodating groove 121. The first busbar 31 is located in the accommodating groove 121. The cover plate 50 is provided on the outer side wall 12 of the housing 10 and covers the receiving groove 121.

Thus, the product volume is reduced.

In particular, referring to fig. 5 to 8, in one embodiment, the first case 13 and the second case 14 may be coupled to each other by bolts and enclosed to form the accommodating chamber 11. In the case where the battery cell 20 is vertically placed in the housing chamber 11 and the first fixing member 1111 is provided at the bottom of the housing chamber 11, the housing groove 121 is also provided at the bottom of the housing 10. The outer side wall 12 of the bottom of the housing 10 is recessed inward to form a receiving groove 121, and the outer side wall 12 is the bottom wall of the housing 10. The first terminal 22 of the battery cell 20 passes through the first fixing member 1111 through the first through hole 1112 so as to enter the receiving groove 121. The first bus bar 31 may be connected to the first pole 22 in the receiving groove 121. Thus, the first pole 22 and the first bus bar 31 can be integrated at the bottom of the housing 10, thereby improving the overall integration degree to reduce the product volume. By providing the cover plate 50 to cover the receiving groove 121, the integrity of the housing 10 can be further improved and the first pole 22 and the first bus bar 31 can be protected. The cover plate 50 is fixed to the housing 10 by bolts, but may be fixed by other means, and is not limited thereto.

Referring to fig. 5-8, in some embodiments, the stored energy power source 100 includes a thermal conductive gel. The heat conductive paste connects the cover plate 50 and the first bus bar 31.

In this way, the temperature of the first bus bar 31 can be reduced.

In particular, referring to fig. 5 to 8, in one embodiment, a certain current loss is generated and heat is generated when a current flows through the first bus bar 31. The accumulated heat may cause the temperature of the first busbar 31 and the battery cell 20 to rise, resulting in fire safety hazards. Therefore, by filling the heat-conducting glue between the first busbar 31 and the cover plate 50, the heat of the first busbar 31 can be transferred to the cover plate 50, so that the heat is emitted to the surrounding environment through the cover plate 50 to achieve the effect of cooling the first busbar 31 and the battery cells 20. The cover plate 50 may be made of aluminum material, thereby providing a good heat transfer effect. Meanwhile, the shell 10 can also adopt materials with good heat transfer effects such as aluminum materials and the like so as to further transfer the heat of the cover plate 50 to the shell 10 and improve the cooling effect on the first busbar 31 and the battery cell 20.

Referring to fig. 5 and 6, in some embodiments, the stored energy power source 100 further includes a seal ring 60. The sealing ring 60 seals the cover plate 50 to the outer side wall 12 of the housing 10.

In this way, the sealing effect of the storage groove 121 can be improved.

Specifically, referring to fig. 5 and 6, in one embodiment, the outer sidewall 12 of the housing 10 is formed with a receiving groove 121. The accommodating groove 121 accommodates the bus bar assembly 30.
