[0041] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0042] As Figure 1 shown, a mobile power supply according to an embodiment of the present utility model includes a housing 1, a battery management circuit board 2 and a heat dissipation module 3.

[0043] At least part of the housing 1 is heat - conductive. For example, the housing 1 can be a rectangular box - shaped structure as a whole, and a part of the housing 1 can be made of a metal material, so that this part of the housing 1 has good heat conduction performance. In some other embodiments, the housing 1 can be made of a metal material as a whole, so that any part of the housing 1 has heat conduction performance.

[0044] The battery management circuit board 2 is arranged in the housing 1. For example, the battery management circuit board 2 can be a battery management system (BMS). The battery management circuit board 2 can be fixed in the housing 1 and located above the battery assembly 4. During use, the battery management system can intelligently manage and maintain each battery unit, and can monitor the state of the battery. For example, it can monitor the temperature of the battery.

[0045] The heat dissipation module 3 is arranged on the battery management circuit board 2 and is located between the battery management circuit board 2 and the housing 1, and the heat dissipation module 3 is used to conduct the heat generated by the battery management circuit board 2 to the housing 1 for dissipation through the housing 1.

[0046] For example, the heat dissipation module 3 can be fixed on the upper side of the battery management circuit board, and the heat dissipation module 3 can be located between the battery management circuit board 2 and the top wall of the housing 1. The heat dissipation module 3 has good heat dissipation performance and / or heat conduction performance. For example, the heat dissipation module 3 can also be a liquid - cooling plate, etc.

[0047] When in use, the heat generated by the battery management circuit board 2 can be quickly conducted to the heat conductive part of the shell 1 through the heat dissipation module 3, and then the heat can be quickly dissipated to the outside of the mobile power supply through the heat conductive part of the shell 1, thereby achieving the effect of heat dissipation and cooling.

[0048] In the mobile power supply of this embodiment, the heat dissipation module 3 can quickly conduct the heat generated by the battery management circuit board 2 to the shell 1. Since the shell 1 has a large heat dissipation area, the heat can be quickly dissipated, avoiding the situation where heat is accumulated on the battery management circuit board 2. It also avoids the problem that the shell 1 is a sealed structure and cannot dissipate heat, thereby improving the overall heat dissipation performance, ensuring the long-term and stable use of the mobile power supply, and improving the safety of use.

[0049] In some embodiments, the heat dissipation module 3 includes a heat conductor 31, which is disposed on the battery management circuit board 2, at least a portion of the heat conductor 31 is attached to the battery management circuit board 2, and the heat conductor 31 is used to conduct heat on the circuit board to the heat dissipation module 3.

[0050] For example, Figure 1 and Figure 2 As shown, the heat conductive member 31 may be a plate-shaped structure, and the material of the heat conductive member 31 may be a material with good thermal conductivity, such as aluminum alloy, copper, etc. The heat conductive member 31 may be attached and fixed to the upper surface of the battery management circuit board 2, and the heat on the battery management circuit board 2 may be quickly transferred outwards through the heat conductive member 31 by the attached contact between the heat conductive member 31 and the battery management circuit board 2, thereby ensuring the overall heat dissipation effect.

[0051] In some embodiments, the heat dissipation module 3 further includes a fan 32 disposed in the housing 1 . The fan 32 is disposed on a side of the heat conducting member 31 away from the circuit board, and the fan 32 is used to cool the heat conducting member 31 by air.

[0052] For example, Figure 1 and Figure 2 As shown, after the heat-conducting member 31 is fitted on the battery management circuit board 2, the fan 32 can be fixed to the upper side of the heat-conducting member 31 by fasteners, and the fan 32 can be located between the heat-conducting member 31 and the top shell wall of the shell 1. When in use, the running fan 32 can quickly blow the heat on the heat-conducting member 31 to the top shell wall of the shell 1, thereby accelerating the heat dissipation.

[0053] In some embodiments, the housing 1 includes a bottom shell 11 and a top cover 12. The top side of the bottom shell 11 is provided with an opening, and the top cover 12 is detachably sealed at the opening. Figure 1As shown, the bottom case 11 can generally be a square box-like structure, and the material of the bottom case 11 can be metal. The top cover 12 can generally be a rectangular plate-like structure, and the material of the top cover 12 can be plastic or the like. The top cover 12 can be fixed to the top side of the bottom case 11 through fasteners such as screws. Thus, after the battery assembly 4, the battery management circuit board 2, and the heat dissipation module 3 are placed in the bottom case 11, the opening on the top side of the bottom case 11 can be sealed, achieving the effect of isolation and protection.

[0054] In some embodiments, the mobile power supply further includes a battery assembly 4. The battery assembly 4 is disposed in the housing 1. The battery assembly 4 includes a bracket 43 and a plurality of single-cell batteries 44. The plurality of single-cell batteries 44 are all arranged in parallel on the bracket 43.

[0055] For example, as Figure 1 shown, the battery assembly 4 can include two independent parts, which are the positive battery assembly 41 and the negative battery assembly 42 respectively. The structures of the positive battery assembly 41 and the negative battery assembly 42 can be generally the same and can be arranged relatively in the left-right direction.

[0056] Such as Figure 2 shown, both the positive battery assembly 41 and the negative battery assembly 42 can include an independent bracket 43 and a plurality of single-cell batteries 44. The plurality of single-cell batteries 44 can all be embedded in the bracket 43. The axial direction of each single-cell battery 44 can extend along the left-right direction, and the plurality of single-cell batteries 44 can all be arranged in parallel and spaced apart in the vertical plane.

[0057] One electrode of each single-cell battery 44 is located on the first side 45 of the bracket 43, and the other electrode is located on the second side 46 of the bracket 43. The first side 45 and the second side 46 are opposite sides. The battery management circuit board 2 is electrically connected to the single-cell batteries 44.

[0058] For example, taking the positive battery assembly 41 on the left side as an example, as Figure 3 shown, the first side 45 can be the left side of the positive battery assembly 41, and the second side 46 can be the right side of the positive battery assembly 41. Each single-cell battery 44 can extend along the left-right direction, and one of the positive and negative electrodes of each single-cell battery 44 can be arranged facing the first side 45, and the other of the positive and negative electrodes can be arranged facing the second side 46.

[0059] The battery management circuit board 2 can be electrically connected to the above-mentioned positive battery assembly 41 and negative battery assembly 42 through structures such as connection rows, and thus can be electrically connected to each single-cell battery 44 in each battery assembly 4.

[0060] In some embodiments, the multiple single-cell batteries 44 are divided into multiple battery groups. The single-cell batteries 44 in each battery group have the same electrodes on the first side 45 of the bracket 43 and the same electrodes on the second side 46 of the bracket 43. The number of single-cell batteries 44 in each battery group is the same. The single-cell batteries 44 in two adjacent battery groups have different electrodes on the first side 45 of the bracket 43 and different electrodes on the second side 46 of the bracket 43.

[0061] For example, as Figure 4 shown, each battery group can include three single-cell batteries 44. The three single-cell batteries 44 can be arranged in an L shape, and the positive electrodes of the three single-cell batteries 44 can all face one of the first side 45 and the second side 46, and the negative electrodes of the three single-cell batteries 44 can all face the other of the first side 45 and the second side 46. In some other embodiments, four, five or other numbers of single-cell batteries 44 can also be provided in each battery group.

[0062] For example, as Figure 4 shown, one of two adjacent battery groups can be labeled A, and the other can be labeled B. The positive electrodes of the three single-cell batteries 44 in the battery group labeled A can all face the first side 45, and the negative electrodes of the three single-cell batteries 44 can all face the second side 46. The positive electrodes of the three single-cell batteries 44 in the battery group labeled B can all face the second side 46, and the negative electrodes of the three single-cell batteries 44 can all face the first side 45. Thus, it provides convenience for the subsequent series connection of two adjacent battery groups.

[0063] The battery assembly 4 further includes a first electrode connector 47 and a second electrode connector 48. The first electrode connector 47 is located on the first side 45 of the bracket 43 and is used to electrically connect the same electrodes on the first side 45 of the single-cell batteries 44 in the same battery group. The second electrode connector 48 is located on the second side 46 of the bracket 43 and is used to electrically connect the same electrodes on the second side 46 of the single-cell batteries 44 in the same battery group, so that the single-cell batteries 44 in each battery group are connected in parallel.

[0064] For example, taking the positive electrode battery assembly 41 as an example, the battery assembly 4 can include multiple first electrode connectors 47 and multiple second electrode connectors 48. The materials of the first electrode connector 47 and the second electrode connector 48 can both be conductive materials such as aluminum.

[0065] A plurality of first electrode connectors 47 can all be arranged on the left side of the positive electrode battery assembly 41. One end of each of the multiple single cells 44 in each cell assembly can be electrically connected to the corresponding same first electrode connector 47. A plurality of second electrode connectors 48 can all be arranged on the right side of the positive electrode battery assembly 41. The other end of each of the multiple single cells 44 in each cell assembly can be electrically connected to the corresponding same second electrode connector 48. Thus, a parallel design of the multiple single cells 44 in the same cell group is achieved.

[0066] The first electrode connector 47 is further configured to electrically connect different electrodes of two adjacent cell groups located on the first side 45 of the bracket 43, and the second electrode connector 48 is further configured to electrically connect different electrodes of two adjacent cell groups located on the second side 46 of the bracket 43, so that each cell group is connected in series.

[0067] For example, as Figure 4 shown, each first electrode connector 47 can be connected to a cell group A and a cell group B at the same time. Through this first electrode connector 47, a series design of the cell group A and the cell group B can be achieved.

[0068] Similarly, as Figure 5 shown, each second electrode connector 48 can also be connected to a cell group A and a cell group B at the same time. Through this second electrode connector 48, a series design of the cell group A and the cell group B can also be achieved.

[0069] In some embodiments, as Figure 4 shown, the electrodes of the single cells 44 on the same side of the bracket 43 are arranged in a rectangular array, that is, multiple single cells 44 can be arranged in columns along the vertical direction and in rows along the horizontal direction. This is beneficial to improving the space utilization rate of the arrangement of the single cells 44, and further can achieve the effect of improving the energy density.

[0070] In some embodiments, as Figure 4 shown, the first electrode connector 47 is a rectangular electrode connecting piece. As Figure 5 shown, the second electrode connector 48 is a trapezoidal electrode connecting piece. Thus, the shapes of the respective electrode connectors are adapted to the arrangement of the cell groups, thereby facilitating the connection and arrangement with the cell groups.

[0071] In some embodiments, a plurality of components are provided on the battery management circuit board 2. The plurality of components include power devices 22, and at least part of the heat conducting members 31 are arranged adjacent to the power devices 22. For example, as Figure 6 shown, the battery management circuit board 2 can include a circuit board body 21 and a plurality of components mounted on the circuit board body 21. The components can be diodes, triodes, resistors, capacitors, etc.

[0072] The power device 22 can be a MOS transistor. The heat conducting member 31 can generally be in a plate-like structure. The heat conducting member 31 can be fixed on the circuit board body 21, and the power device 22 can be located between the heat conducting member 31 and the circuit board body 21. Since a large amount of heat is generated when the power device 22 is operating, arranging the heat conducting member 31 adjacent to the power device 22 can enable the heat generated by the power device 22 to be quickly conducted outward through the heat conducting member 31, so that the arrangement of the heat conducting member 31 is more targeted and can also enhance the heat dissipation and temperature reduction effect.

[0073] In some embodiments, the heat dissipation module 3 further includes a heat conducting layer 33. The heat conducting layer 33 is disposed between the heat conducting member 31 and at least some of the components, and the heat conducting layer 33 is used to conduct the heat generated by the components to the heat conducting member 31.

[0074] For example, as Figure 6 shown, the heat conducting layer 33 can be a heat dissipation silica gel layer, and a heat conducting layer 33 can be bonded between each component and the heat conducting member 31. Thus, the heat generated by each component can be quickly conducted to the heat conducting member 31 through the heat conducting layer 33, thereby improving the heat dissipation and temperature reduction effect.

[0075] In some other embodiments, the material of the heat conducting layer 33 can also be a graphite heat conducting sheet, a graphene heat conducting sheet layer, etc.

[0076] In some embodiments, the heat conducting member 31 conforms to the height change of at least one component. For example, the shape of the heat conducting member 31 can adaptively change with the height change of each component. Thus, the overall shape of the heat conducting member 31 can be more in line with the outer shape of the battery management circuit board 2, which is beneficial to improving the structural compactness of the assembly.

[0077] In some embodiments, the heat conducting member 31 includes a plurality of fins, and the plurality of fins are arranged at intervals along the circumferential direction of the heat conducting member 31. For example, the heat conducting member 31 can be circular, the fins can be heat dissipation fins, and the fins can be fixed on the same side of the heat conducting member 31, for example, can be disposed on the side of the heat conducting member 31 facing away from the battery management circuit board 2, and the plurality of fins can be arranged at equal intervals along the circumferential direction of the heat conducting member 31, thereby further improving the heat dissipation and temperature reduction effect.

[0078] In some embodiments, an airtight hole 13 is provided on the housing 1, and the housing 1 contains a coolant injected through the airtight hole 13. For example, as Figure 7 shown, the airtight hole 13 can be a stepped hole, and the airtight hole 13 can be provided on the top cover 12. During assembly, the airtight detection of the housing 1 can be realized through the airtight hole 13, so as to ensure the waterproof and airtight performance of the housing 1. Secondly, media such as coolant can also be injected into the housing 1 through the airtight hole 13, thereby further improving the heat dissipation and temperature reduction effect of the mobile power supply.

[0079] In some embodiments, as Figure 7 shown, after the airtight detection is completed or the coolant injection is completed, the airtight hole 13 can be sealed by the plugging member 14, and the plugging member 14 can include bolts, gaskets, etc., thereby ensuring the overall airtightness of the housing 1.

[0080] Although the above embodiments have been shown and described, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions, and variations made by those of ordinary skill in the art to the above embodiments are within the protection scope of the present invention.
