[0038] This utility model provides a battery; please refer to [reference needed]. Figures 1 to 4 The device includes a housing 10 and a battery cell 20. The housing 10 has a receiving protrusion 11 for accommodating the battery cell 20 and a clearance recess 12 for avoiding a vehicle beam. The clearance recess 12 penetrates the housing 10 along a first preset direction, and the opening of the clearance recess 12 is oriented towards a second preset direction. Along a third preset direction, both sides of the clearance recess 12 have receiving protrusions 11. The first preset direction, the second preset direction, and the third preset direction are perpendicular to each other.

[0039] The battery of this utility model includes a housing 10 and a battery cell 20. The housing 10 has a receiving protrusion 11 for accommodating the battery cell 20 and a clearance recess 12 for avoiding the beam of a vehicle. Since the clearance recess 12 has a receiving protrusion 11 on both sides in the third preset direction, each receiving protrusion 11 can accommodate the battery cell, so that the space of the housing 10 is fully utilized, more battery cells can be accommodated in a unit volume, the space utilization rate is improved, and the energy density of the battery is improved, thus solving the problem of low energy density of batteries in the prior art.

[0040] It should be noted that the first preset direction is the width direction of the battery, the second preset direction is the height direction of the battery, and the third preset direction is the length direction of the battery.

[0041] Specifically, the housing 10 is provided with at least two battery layers 30 stacked along a second preset direction. Each battery layer 30 includes a battery cell 20, and the at least two battery layers 30 include a first battery layer 31 disposed within the receiving protrusion 11. In specific implementation, the arrangement of at least two battery layers 30 allows the battery to accommodate more battery cells, thereby increasing the energy density of the battery; furthermore, the first battery layer 31 being disposed within the receiving protrusion 11 further improves space utilization, thereby increasing the energy density of the battery.

[0042] Specifically, the housing 10 has a plurality of receiving protrusions 11 arranged sequentially along a third preset direction, and a clearance recess 12 is provided between two adjacent receiving protrusions 11; wherein, the first battery layer 31 includes a plurality of battery cells 20, and the plurality of battery cells 20 of the first battery layer 31 are arranged in a one-to-one correspondence with the plurality of receiving protrusions 11, and each battery cell 20 of the first battery layer 31 is disposed within the corresponding receiving protrusion 11. In specific implementation, each clearance recess 12 is used to avoid the main beam, meeting the actual use requirements; the first battery layer 31 is arranged with gaps, increasing the space utilization rate of the battery.

[0043] Specifically, the tops of the multiple receiving protrusions 11 are aligned flush with each other in a second predetermined direction. This arrangement makes the multiple receiving protrusions 11 have the same structure, and each of the multiple receiving protrusions 11 can accommodate a single battery cell, thereby improving space utilization and thus increasing the energy density of the battery.

[0044] Specifically, the housing 10 has three receiving protrusions 11 and two abutment recesses 12, with an abutment recess 12 provided between any two adjacent receiving protrusions 11; the first battery layer 31 includes three battery cells 20, which are respectively disposed within the three receiving protrusions 11. In practical implementation, the battery typically needs to avoid the two main beams of the vehicle, with the two main beams respectively disposed within the corresponding abutment recesses 12. This arrangement satisfies both the battery installation requirements and ensures the battery's energy density.

[0045] Specifically, the housing 10 includes a box body 13 and a box cover 14 covering the box body 13, the box cover 14 having a receiving protrusion 11 and a relief recess 12; at least two battery layers 30 include a second battery layer 32 disposed within the box body 13.

[0046] Optionally, the battery includes two battery layers 30, namely a first battery layer 31 and a second battery layer 32.

[0047] Specifically, the second battery layer 32 includes at least two battery cells 20, which are arranged sequentially in the housing 13 along a third preset direction.

[0048] Specifically, the housing 10 further includes at least one reinforcing plate, which is disposed within and fixedly connected to the housing 13 to divide the housing 13 into at least two cavities for accommodating the battery cells 20. In practice, the reinforcing plate can increase the overall strength of the housing 10. The reinforcing plate is welded to the housing 10.

[0049] Optionally, the housing 10 includes a reinforcing plate to divide the housing 13 into two cavities, each of which houses a battery cell 20.

[0050] Specifically, the battery includes at least two heat exchangers, each having a cavity for containing a heat exchange medium. The at least two heat exchangers include: a first heat exchanger 41, disposed at the bottom of the housing 10, with the bottom battery layer 30 of the at least two battery layers 30 disposed on and in contact with the first heat exchanger 41; and a second heat exchanger 42, disposed within the housing 10, with a second heat exchanger 42 disposed between any two adjacent battery layers 30, and the battery layers 30 on both sides of the second heat exchanger 42 in contact with it. Because this battery incorporates the first heat exchanger 41 and the second heat exchanger 42, both of which are in contact with their respective battery layers 30, it achieves high heat transfer efficiency, improving the cooling capacity of the battery's cooling system and solving the problem of insufficient cooling efficiency in existing battery cooling systems.

[0051] It should be noted that the bonding of the first heat exchanger 41 and the second heat exchanger 42 with the corresponding battery layer 30 can include direct bonding and indirect bonding. The bonding structure has a better heat transfer effect and is more efficient than heat conduction through air with gaps.

[0052] Specifically, the first heat exchanger 41 is fixedly connected to the bottom of the housing 10. This arrangement increases the strength of the battery.

[0053] Specifically, the battery also includes heat exchange piping, with at least two heat exchange elements connected to the heat exchange piping, so that the at least two heat exchange elements are connected in parallel or in series. This configuration makes the cooling system connection flexible and can adapt to the cooling requirements under different operating conditions.

[0054] Specifically, the battery includes two battery layers 30; the heat exchange pipeline includes a main inflow pipe 431, a first inflow pipe 432, and a second inflow pipe 433. One end of the first inflow pipe 432 and one end of the second inflow pipe 433 are respectively connected to the main inflow pipe 431, and the other ends of the first inflow pipe 432 and the second inflow pipe 433 are respectively connected to the receiving cavity of the first heat exchanger 41 and the receiving cavity of the second heat exchanger 42, so that the heat exchange medium enters the first heat exchanger 41 through the main inflow pipe 431, the first inflow pipe 432, and the second inflow pipe 433. The first heat exchanger 435 and the second heat exchanger 436; and / or the main outlet pipe 434, the first outlet pipe 435 and the second outlet pipe 436, one end of the first outlet pipe 435 and one end of the second outlet pipe 436 are respectively connected to the main outlet pipe 434, and the other end of the first outlet pipe 435 and the other end of the second outlet pipe 436 are respectively connected to the receiving cavity of the first heat exchanger 41 and the receiving cavity of the second heat exchanger 42, so that the heat exchange medium in the first heat exchanger 41 and the second heat exchanger 42 flows out through the first outlet pipe 435, the second outlet pipe 436 and the main outlet pipe 434.

[0055] Specifically, the main inflow pipe 431, the first inflow pipe 432, and the second inflow pipe 433 are connected through the first tee interface 44, and the main outflow pipe 434, the first outflow pipe 435, and the second outflow pipe 436 are connected through the second tee interface 45.

[0056] In specific implementation, the configuration of the main inlet pipe 431, the first inlet pipe 432 and the second inlet pipe 433, and the main outlet pipe 434, the first outlet pipe 435 and the second outlet pipe 436 enables the two battery layers 30 to be connected in parallel. The water flow path is as follows: the water flows sequentially through the vehicle outlet, the vehicle water system, the main inlet pipe 431, and the first T-junction 44, then flows into the two battery layers 30 through the first inlet pipe 432 and the second inlet pipe 433 respectively. After heat exchange, the water flows out from the two battery layers 30, flows through the first outlet pipe 435 and the second outlet pipe 436 respectively, merges at the second T-junction 45, and then flows out sequentially through the main outlet pipe 434, the vehicle water system, and the vehicle return outlet. In addition, the flow rate of the heat exchange pipeline can be controlled by adjusting the diameter of the first inlet pipe 432 and the second inlet pipe 433, and the first outlet pipe 435 and the second outlet pipe 436, thereby improving the temperature distribution.

[0057] Specifically, the accommodating cavity of each heat exchanger is used to accommodate either a cooling medium or a heating medium, so that the heat exchanger can cool or heat at least two battery layers 30. This arrangement allows for heating of the individual battery layers not only using heating elements but also using the heat exchanger itself.

[0058] Optionally, the heating medium is a liquid.

[0059] Specifically, the second heat exchanger 42 is fixedly connected to the housing 10. This arrangement increases the strength of the battery. The second heat exchanger 42 is also fixedly connected to the side wall of the housing 13.

[0060] In specific implementation, the second battery layer 32 is cooled by the first heat exchanger 41 and the second heat exchanger 42, and the first battery layer 31 is cooled by the second heat exchanger 42.

[0061] Specifically, the battery includes multiple heating elements, including a first heating element 51, a second heating element 52, and a third heating element 53. A first heating element 51 is disposed between any two adjacent battery layers 30; a second heating element 52 is disposed on the underside of the bottom battery layer 30 in at least two battery layers 30; and a third heating element 53 is disposed on the upper side of the top battery layer 30 in at least two battery layers 30. Thus, by distributing heating elements between any two adjacent battery layers 30, on the underside of the bottom battery layer 30 in at least two battery layers 30, and on the upper side of the top battery layer 30 in at least two battery layers 30, the battery layer 30 can be heated by the heating elements on both the upper and lower sides, achieving efficient heating of each battery layer 30, improving heating capacity and efficiency, and ensuring heating uniformity between each battery layer 30.

[0062] Specifically, the battery layers 30 on both sides of the first heating element 51 are attached to it; the second heating element 52 is attached to the battery layer 30 on its upper side; and the third heating element 53 is attached to the battery layer 30 on its lower side.

[0063] It should be noted that the above-mentioned bonding can be direct bonding or indirect bonding, that is, there are other structures in between, but the heat transfer efficiency of the other structures is still higher than that of air (when there are gaps between them). In specific implementation, the bonding arrangement of the first heating element 51, the second heating element 52 and the third heating element 53 can further improve the heating efficiency.

[0064] Specifically, the heating element includes a sheet body and heating elements disposed on the sheet body; the heating element includes a first sheet body and a second sheet body, the second sheet body being disposed around the first sheet body, and the number of heating elements in the second sheet body being greater than the number of heating elements in the first sheet body. This arrangement makes the temperature more uniform during heating.

[0065] Optionally, the heating power of the heating element in the second sheet is greater than that of the heating element in the first sheet; and / or, the heating area of ​​the heating element in the second sheet is greater than that of the heating area of ​​the heating element in the first sheet. This arrangement can also make the temperature more uniform during heating. It should be noted that the heating area refers to the area of ​​the projection of the heating element onto the first or second sheet.

[0066] Specifically, the heating element is a heating wire, and the number of heating wires in the second sheet is greater than the number of heating wires in the first sheet. In actual implementation, the heating wires are not uniformly distributed, with fewer heating wires in the middle and more around the edges, so that the temperature is more uniform during heating; the density of the heating wire arrangement can be determined through thermal simulation.

[0067] Specifically, each battery cell 20 within the receiving protrusion 11 is provided with a third heating element 53, which ensures that each battery cell 20 is heated.

[0068] Specifically, the heating element is bonded. This design facilitates the installation of the heating element.

[0069] Specifically, a temperature sensor is provided on the multi-layer battery layer 30. The temperature sensor collects the temperature of the multi-layer battery layer 30 and feeds the temperature back to the battery management system, so that the battery management system can control the heating element.

[0070] Specifically, the second heating element 52 is disposed between the first heat exchanger 41 and the bottom battery layer 30 (i.e., the second battery layer 32) of at least two battery layers 30, and the two sides of the second heating element 52 are respectively attached to the first heat exchanger 41 and the second battery layer 32; the second heat exchanger 42 is disposed inside the housing 10, and the second heat exchanger 42 is disposed between the first heating element 51 and the battery layer 30 (i.e., the first battery layer 31) located above it, and the two sides of the second heat exchanger 42 are respectively attached to the first heating element 51 and the first battery layer 31.

[0071] This utility model provides a vehicle, including a battery, which is the battery described in the above embodiment.

[0072] This invention designs a high-efficiency, integrated battery. By optimizing the layout of the battery casing, cooling system, individual battery cells, and related components, it improves the cooling and heating efficiency of the battery system while solving the space avoidance problem between the battery cover and the individual battery cells. This solution, through layered arrangement of battery layers and heat exchange plates, combined with a layered design of heating elements, effectively improves the thermal management performance of the battery system, extends battery life, and increases overall energy density. Furthermore, by designing avoidance recesses on the battery cover, the arrangement of the upper battery layers is ensured to be unrestricted, thereby improving space utilization.

[0073] This invention optimizes the battery cooling system by introducing an arrangement of the first heat exchanger 41 and the second heat exchanger 42, thereby improving cooling efficiency and heat dissipation uniformity. This arrangement connects the first heat exchanger 41 and the second heat exchanger 42 in parallel via heat exchange pipes, which are then connected to the vehicle's cooling system. This achieves efficient cooling of both battery layers, ensuring the battery maintains a stable temperature under various operating conditions, extending battery life, and improving overall vehicle performance.

[0074] This invention optimizes the arrangement of heating elements, improving heating efficiency and uniformity through the rational configuration of their positions and functions. Specifically, this solution addresses the problems of uneven heating and high energy consumption in existing technologies by setting up a first, second, and third heating element, thereby achieving a more efficient and uniform heating effect.

[0075] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0076] The battery includes a housing 10 and a battery cell 20. The housing 10 has a receiving protrusion 11 for accommodating the battery cell 20 and a clearance recess 12 for avoiding the beam of a vehicle. Since the clearance recess 12 has receiving protrusions 11 on both sides in a third predetermined direction, each receiving protrusion 11 can accommodate the battery cell, so that the space of the housing 10 is fully utilized, more battery cells can be accommodated in a unit volume, the space utilization rate is improved, and the energy density of the battery is improved, thus solving the problem of low energy density of batteries in the prior art.
