Multiple accommodating protrusions 11 are used to accommodate the battery cell 20, which can effectively utilize the space in the shell 10 and accommodate more battery cells 20. In addition, the opening component and the interface component are respectively arranged in the first accommodating protrusion 111 and the second accommodating protrusion 112, which will not occupy the space for arranging the battery cell 20, and the arrangement position is reasonable. It can be seen that the structural setting of the battery improves the energy density of the battery and solves the problem of low energy density of the battery in the prior art.

[0046] 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.

[0047] Specifically, the first accommodating protrusion 111 includes an installation step 113, which is located on a side of the first accommodating protrusion 111 away from the second accommodating protrusion 112; the opening assembly 60 is disposed on the installation step 113.

[0050] Specifically, the opening component 60 includes an installation port opened in the first accommodating protrusion 111, and the heat exchange pipeline of the battery includes a main inlet pipe 431 and a main outlet pipe 434, and the main inlet pipe 431 and the main outlet pipe 434 are both arranged through the installation port; the opening component 60 also includes a sealing member arranged in the installation port, and the sealing member is arranged around the main inlet pipe 431 and the main outlet pipe 434 to seal the gap between the installation port, the main inlet pipe 431 and the main outlet pipe 434, and the setting of the sealing member prevents moisture from entering the interior of the battery.

[0051] Specifically, a first connection portion 437 is provided on the total inflow pipe 431, and a second connection portion 438 is provided on the total outflow pipe 434; the battery further includes a bracket 15 disposed within the housing 10, one end of the bracket 15 is connected to both the first connection portion 437 and the second connection portion 438, and the other end of the bracket 15 is connected to the housing 10. Such a setting realizes the fixation of the heat exchange pipeline.

[0052] Specifically, the interface assembly 70 includes a mounting panel 71 and a plurality of interfaces for connecting to external devices. The mounting panel 71 is mounted on the second receiving convex portion 112, and the plurality of interfaces are spaced apart on the mounting panel 71.

[0053] Specifically, the plurality of interfaces include a negative electrode interface 72 and a positive electrode interface 73 for connecting to external devices; and / or, the plurality of interfaces include a positive signal line interface 74 and a negative signal line interface 75 for communicating with external devices; and / or, the plurality of interfaces include a heating positive electrode interface 76 and a heating negative electrode interface 77 for connecting to external devices, so as to open or close the heating sheet of the battery through the heating positive electrode interface 76 and the heating negative electrode interface 77 to heat the battery layer and ensure the normal operation of the battery in a low-temperature environment; and / or, a power switch 78 is provided on the mounting panel 71 to control the opening and closing of the battery through the power switch 78.

[0054] Specifically, the power switch 78 is a manual service disconnect (MSD).

[0055] Specifically, the tops of the plurality of receiving convex portions 11 are flush with each other in the second preset direction. Such a setting makes the structures of the plurality of receiving convex portions 11 the same, and the plurality of receiving convex portions 11 can all accommodate battery cells, improving the space utilization rate and thus improving the energy density of the battery.

[0056] Specifically, at least two layers of battery layers 30 are stacked in the second preset direction within the housing 10. Each layer of battery layer 30 includes battery cells 20. The at least two layers of battery layers 30 include a first battery layer 31 disposed within the receiving convex portion 11. The first battery layer 31 includes a plurality of battery cells 20. The plurality of battery cells 20 of the first battery layer 31 are arranged in one-to-one correspondence with the plurality of receiving convex portions 11, and each battery cell 20 of the first battery layer 31 is disposed within the corresponding receiving convex portion 11.

[0057] In specific implementation, the setting of the at least two layers of battery layers 30 enables the battery to accommodate more battery cells, improving the energy density of the battery; and, the first battery layer 31 is disposed within the receiving convex portion 11, further improving the space utilization rate and thus improving the energy density of the battery.

[0058] Specifically, the housing 10 has three receiving protrusions 11 and two avoiding recesses 12. One avoiding recess 12 is provided between any two adjacent receiving protrusions 11. The first battery layer 31 includes three battery cells 20, and the three battery cells 20 are respectively arranged in the three receiving protrusions 11. Among them, the left and right receiving protrusions 11 of the three receiving protrusions 11 are the first receiving protrusion 111 and the second receiving protrusion 112 respectively. In specific implementation, usually the battery needs to avoid two main beams of the vehicle, and the two main beams are respectively arranged in the corresponding avoiding recesses 12. Such a setting can not only meet the installation of the battery, but also ensure the energy density of the battery.

[0059] Specifically, the housing 10 includes a box body 13 and a box cover 14 covering the box body 13. The box cover 14 has a receiving protrusion 11 and an avoiding recess 12. The at least two-layer battery layer 30 includes a second battery layer 32 arranged in the box body 13.

[0060] Optionally, the battery includes two battery layers 30, namely a first battery layer 31 and a second battery layer 32.

[0061] Specifically, the second battery layer 32 includes at least two battery cells 20, and the at least two battery cells 20 are sequentially arranged in the box body 13 along a third preset direction.

[0062] Specifically, the housing 10 further includes at least one reinforcing plate. The at least one reinforcing plate is arranged in the box body 13 and fixedly connected to the box body 13 to divide the box body 13 into at least two cavities for accommodating the battery cells 20. In specific implementation, the reinforcing plate can increase the overall strength of the housing 10. Among them, the reinforcing plate is welded to the housing 10.

[0063] Optionally, the housing 10 includes a reinforcing plate to divide the box body 13 into two cavities, and one battery cell 20 is arranged in each cavity.

[0064] Specifically, the battery further includes a first heat exchange member 41 and a second heat exchange member 42. The first battery layer 31 is located above the second battery layer 32. The first heat exchange member 41 is arranged at the bottom in the housing 10, and the second battery layer 32 is arranged on the first heat exchange member 41 and is in contact with the first heat exchange member 41. A second heat exchange member 42 is arranged between the first battery layer 31 and the second battery layer 32, and both sides of the second heat exchange member 42 are in contact with the first battery layer 31 and the second battery layer 32 respectively. Since the battery is provided with the first heat exchange member 41 and the second heat exchange member 42, and both of them are in contact with the corresponding battery layer 30, the heat transfer efficiency is high, the cooling capacity of the battery cooling system is improved, and the problem of insufficient cooling efficiency of the battery cooling system in the prior art is solved.

[0065] It should be noted that the first heat exchanger 41 and the second heat exchanger 42 being in contact with the corresponding battery layer 30 can include direct contact and indirect contact, and the contacting structures both have good heat transfer effects. Compared with heat conduction through air with a gap, the efficiency is higher.

[0066] Specifically, the first heat exchanger 41 is fixedly connected to the bottom of the housing 10. Such a setting increases the strength of the battery.

[0067] Specifically, the heat exchange pipeline includes: a first inflow pipe 432, a second inflow pipe 433, and a first three-way interface 44. One end of the first inflow pipe 432 and one end of the second inflow pipe 433 are respectively connected to the total inflow pipe 431 through the first three-way interface 44. The other end of the first inflow pipe 432 and the other end of the second inflow pipe 433 are respectively connected to the accommodation cavity of the first heat exchanger 41 and the accommodation cavity of the second heat exchanger 42, so that the heat exchange medium enters the first heat exchanger 41 and the second heat exchanger 42 through the total inflow pipe 431, the first inflow pipe 432, and the second inflow pipe 433; a first outflow pipe 435, a second outflow pipe 436, and a second three-way interface 45. One end of the first outflow pipe 435 and one end of the second outflow pipe 436 are respectively connected to the total outflow pipe 434 through the second three-way interface 45. The other end of the first outflow pipe 435 and the other end of the second outflow pipe 436 are respectively connected to the accommodation cavity of the first heat exchanger 41 and the accommodation 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 total outflow pipe 434, the first outflow pipe 435, and the second outflow pipe 436.

[0068] During specific implementation, the settings of the total inflow pipe 431, the first inflow pipe 432, and the second inflow pipe 433, as well as the total outflow pipe 434, the first outflow pipe 435, and the second outflow pipe 436, realize the parallel connection of two layers of battery layers 30. The water flow path is that the water flows through the vehicle water outlet, the vehicle water circuit, the total inflow pipe 431, and the first three-way interface 44 in sequence, and then flows into the two layers of battery layers 30 through the first inflow pipe 432 and the second inflow pipe 433 respectively. After heat exchange, it flows out from the two layers of battery layers 30, passes through the first outflow pipe 435 and the second outflow pipe 436 respectively, converges at the second three-way interface 45, and then flows out through the total outflow pipe 434, the vehicle water circuit, and the vehicle water return port in sequence. In addition, the heat exchange pipeline can control the flow rate by adjusting the diameters of the first inflow pipe 432 and the second inflow pipe 433, and the first outflow pipe 435 and the second outflow pipe 436, thereby improving the temperature distribution.

[0069] Specifically, the accommodation cavity of each heat exchanger is used to accommodate a cooling medium or a heating medium, so that the heat exchanger cools or heats at least two layers of battery layers 30. Such a setting can not only use heating sheets to heat each battery layer, but also use heat exchangers for heating.

[0070] Optionally, the heating medium is a liquid.

[0071] Specifically, the second heat exchanger 42 is fixedly connected to the housing 10. Such a setting increases the strength of the battery. Among them, the second heat exchanger 42 is fixedly connected to the side wall of the box body 13.

[0072] 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.

[0073] Specifically, the battery includes a plurality of heating sheets. The plurality of heating sheets include a first heating sheet 51, a second heating sheet 52, and a third heating sheet 53. A first heating sheet 51 is disposed between the second heat exchanger 42 and the second battery layer 32, and a second heating sheet 52 is disposed between the first heat exchanger 41 and the second battery layer 32; a third heating sheet 53 is disposed on the top of the first battery layer 31. Such a setting enables each battery layer 30 to be heated by the heating sheets on both the upper and lower sides, realizing efficient heating of each battery layer 30, improving the heating capacity and heating efficiency, and ensuring the heating uniformity between each battery layer 30.

[0074] Specifically, the heating sheet includes a sheet body and a heating element disposed on the sheet body; the heating sheet includes a first sheet body and a second sheet body. The second sheet body is disposed around the first sheet body, and the number of heating elements of the second sheet body is greater than the number of heating elements of the first sheet body. Such a setting makes the temperature more uniform during heating.

[0075] Optionally, the heating power of the heating elements of the second sheet body is greater than the heating power of the heating elements of the first sheet body; and / or, the heating area of the heating elements of the second sheet body is greater than the heating area of the heating elements of the first sheet body. Such a setting can also make the temperature more uniform during heating. It should be noted that the heating area refers to the area size of the projection of the heating element on the first sheet body or the second sheet body.

[0076] Specifically, the heating element is a heating wire, and the number of heating wires of the second sheet body is greater than the number of heating wires of the first sheet body. In specific implementation, the heating wires are non-uniformly distributed. There are fewer heating wires in the middle position and more heating wires around. In this way, the temperature will be more uniform during heating; among them, the density of the heating wire arrangement can be determined by thermal simulation.

[0077] Specifically, a third heating sheet 53 is disposed on each battery cell 20 in each receiving convex portion 11. Such a setting ensures heating of each battery cell 20.

[0078] Specifically, the heating sheet is adhesively disposed. Such a setting facilitates the installation of the heating sheet, and the adhesive setting ensures the heating effect without heat transfer through air.

[0079] 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 controls the heating sheet.

[0080] The present invention provides a vehicle including a battery, wherein the battery is the battery of the above embodiment.

[0081] The present invention overcomes the disadvantage of low energy density of the battery and provides a new mountain-shaped battery. By optimizing the structural design of the battery, especially the design of the opening assembly and the interface assembly, the space utilization rate and the cooling efficiency of the battery pack are improved, thereby enhancing the energy density of the battery pack.

[0082] In addition, the present invention optimizes the layout of the battery housing, the cooling system, the battery cells and related components, improves the cooling and heating efficiency of the battery system, and simultaneously solves the problem of space avoidance between the battery box cover and the battery cells. This solution can effectively improve the thermal management performance of the battery system, extend the battery life, and enhance the overall energy density by arranging the battery layers and the heat exchange plates in layers and combining the layered design of the heating sheets. In addition, by designing a relief recess on the battery box cover, the arrangement of the upper battery layer is not restricted, thereby improving the space utilization rate; and by introducing the arrangement scheme of the first heat exchange member 41 and the second heat exchange member 42, the cooling efficiency and the heat dissipation uniformity are improved. This solution connects the first heat exchange member 41 and the second heat exchange member 42 in parallel through the heat exchange pipeline and connects them to the vehicle cooling system, so as to achieve efficient cooling of the two-layer battery layer, ensure that the battery can maintain a stable temperature under various working conditions, extend the battery life and improve the vehicle performance; and by reasonably configuring the position and function of the heating sheet, the heating efficiency and the heating uniformity are improved. Specifically, this solution sets the first heating sheet, the second heating sheet and the third heating sheet to solve the problems of uneven heating and high energy consumption in the prior art, so as to achieve a more efficient and uniform heating effect.

[0083] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0084] The battery of the present invention includes a housing 10 and battery cells 20.
