Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of batteries, in particular to a battery, a vehicle and a battery swap station. BACKGROUND

[0002] The shell of a general battery does not have a mounting structure. When such a battery is mounted to a vehicle, the battery needs to be first loaded into a battery swap frame that accommodates the battery, and then the battery swap frame is locked to the vehicle. Due to the introduction of the battery swap frame, the required installation space is large, and in the case of limited underbody space, it is difficult to improve the volumetric energy density of the battery, affecting the cruising range of the vehicle. Moreover, due to the small ground clearance of the battery, during the battery swap operation, the battery swap station needs to be pre-installed with a trench, or the vehicle needs to be lifted, resulting in high battery swap cost.

It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an overly literal sense unless expressly so defined herein.

[0062] Reference throughout this application to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all directed to the same embodiment, or to one or more of the alternative embodiments.

[0063] In the description of the application, it is necessary to note that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0064] The term "and / or" in this application is only a description of the association relationship between the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in this application generally represents that the front and rear associated objects have an "or" relationship.

[0065] In the embodiments of the application, the same reference signs represent the same parts, and for the sake of brevity, the detailed description of the same parts is omitted in different embodiments. It should be understood that the thickness, length and width of various components in the embodiments of the application shown in the drawings, as well as the overall thickness, length and width of the integrated device, are only exemplary and should not constitute any limitation on the application.

[0066] "Multiple" appearing in the application refers to two or more (including two).

[0067] In the present application, the battery monomer can include a lithium ion secondary battery, a lithium ion primary battery, a lithium-sulfur battery, a sodium lithium ion battery, a sodium ion battery, or a magnesium ion battery, etc. The present application embodiment is not limited to this. The battery monomer can be in the shape of a cylinder, a flat body, a cuboid, or other shapes, etc. The present application embodiment is not limited to this. The battery monomer is generally divided into three types according to the packaging method: cylindrical battery monomers, square battery monomers, and soft package battery monomers. The present application embodiment is not limited to this.

[0068] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery monomers to provide higher voltage and capacity. The battery of the present application embodiment includes a shell for packaging one or more battery monomers or multiple battery modules. The shell can prevent liquid or other foreign matter from affecting the charging or discharging of the battery monomer.

[0069] In the battery, multiple battery monomers can be connected in series, in parallel, or in a mixed connection. The mixed connection means that there are both series and parallel connections among the multiple battery monomers. The multiple battery monomers can be directly connected in series, in parallel, or in a mixed connection, and then the whole of the multiple battery monomers is accommodated in the shell. Of course, the battery can also be in the form of multiple battery modules connected in series, in parallel, or in a mixed connection, and then multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, which is accommodated in the shell. In addition, the battery can also include other structures, for example, the battery can also include a busbar component for realizing the electrical connection between the multiple battery monomers.

[0070] The battery monomer includes a packaging shell, an electrode assembly, and an electrolyte. The packaging shell is used to accommodate the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet, and a separator. The battery monomer mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The positive electrode sheet includes a positive current collector and a positive active material layer, and the positive active material layer is coated on the surface of the positive current collector. The positive current collector without the positive active material layer protrudes from the positive current collector with the positive active material layer, and the positive current collector without the positive active material layer serves as a positive tab. Taking a lithium ion battery as an example, the material of the positive current collector can be aluminum, and the positive active material can be lithium cobaltate, lithium iron phosphate, ternary lithium, or lithium manganate, etc. The negative electrode sheet includes a negative current collector and a negative active material layer, and the negative active material layer is coated on the surface of the negative current collector. The negative current collector without the negative active material layer protrudes from the negative current collector with the negative active material layer, and the negative current collector without the negative active material layer serves as a negative tab. The material of the negative current collector can be copper, and the negative active material can be carbon or silicon, etc. In order to ensure that the fuse does not occur when passing a large current, the number of positive tabs is multiple and stacked together, and the number of negative tabs is multiple and stacked together. In addition, the electrode assembly can be a winding type structure or a stacked type structure, and the present application embodiment is not limited to this.

[0071] In recent years, new energy vehicles have developed by leaps and bounds. In the field of electric vehicles, batteries, as the power source of electric vehicles, play an irreplaceable important role. As core components of new energy vehicles, batteries have high requirements in terms of safety and cycle life.

[0072] The inventor finds that the general battery shell does not have a mounting structure. When such a battery is installed in a vehicle, the battery needs to be first installed in a battery replacement frame that accommodates it, and then the battery replacement frame is locked to the vehicle. Due to the introduction of the battery replacement frame, the required installation space is large, and in the case of limited underbody space, it is difficult to improve the volumetric energy density of the battery, affecting the vehicle's range. Moreover, due to the small ground clearance of the battery, during battery replacement operations, the battery replacement station needs to be pre-installed with a trench or the vehicle needs to be lifted, resulting in high battery replacement costs.

[0073] Based on the above considerations, the inventor has designed a battery through in-depth research. By providing a mounting structure on the battery shell that can be detachably connected to the vehicle's underbody longitudinal beam, the battery can be installed on the underbody longitudinal beam using the mounting structure to achieve the installation of the battery in the vehicle. Thus, the battery replacement frame used to accommodate the battery in the related art is eliminated, and the installation space ratio of the battery replacement frame is reduced, thereby increasing the volumetric energy density of the battery and increasing the ground clearance of the battery to some extent. Thus, in some cases, the battery replacement station can not need to be dug with a trench, nor does the vehicle need to be lifted, thereby reducing the cost of battery replacement.

[0074] Please refer to Figure 1 , Figure 1 The structural schematic diagram of the vehicle 1000 is provided for some embodiments of the present application. The vehicle 1000 can be a fuel vehicle, a gas vehicle, or a new energy vehicle, which can be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc. The battery 1 can be used for power supply of the vehicle 1000, for example, the battery 1 can be used as the operating power supply of the vehicle 1000. The vehicle 1000 can also include a controller and a motor, and the controller is used to control the battery 1 to supply power to the motor, for example, to meet the power demand of the vehicle 1000 during starting, navigation, and driving. In some embodiments of the present application, the battery 1 can not only be used as the operating power supply of the vehicle 1000, but also be used as the driving power supply of the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0075] As shown in Figure 2 and Figure 3 , the battery 1 includes a battery monomer 4, a shell 5 accommodating the battery monomer 4, and a mounting structure 6 provided on the shell 5 and a docking structure 7 provided on the shell 5. In combination with Figure 4 and Figure 5The mounting structure 6 is adapted to be located between the shell 5 and the vehicle bottom longitudinal beam 200 of the vehicle 1000, and is used to detachably mount the battery 1 to the vehicle bottom longitudinal beam 200. The docking structure 7 is used to dock with the vehicle 1000 to realize current conduction and / or liquid conduction.

[0076] Herein, "longitudinal direction" refers to the length direction of the vehicle 1000 (for example, the X direction marked in FIG. 1), or the front-rear direction of the vehicle 1000, "transverse direction" refers to the width direction of the vehicle 1000 (for example, the Y direction marked in FIG. 1), or the left-right direction of the vehicle 1000, and "vertical direction" refers to the height direction of the vehicle 1000 (for example, the Z direction marked in FIG. 1), or the up-down direction of the vehicle 1000. Figure 4 Figure 4 Figure 4

[0077] In the above embodiment, the number and arrangement of the battery cells 4 accommodated in the shell 5 are not limited, and can be one or more. If there are multiple battery cells 4, the multiple battery cells 4 can be arranged in groups or individually.

[0078] In the above embodiment, the mounting structure 6 on the shell 5 is not limited, and can be an integral part of the shell 5, or a separate part of the shell 5 and directly or indirectly mounted to the shell 5. In the above embodiment, since the mounting structure 6 detachably mounts the battery 1 to the vehicle bottom longitudinal beam 200, the battery 1 is detachable relative to the vehicle 1000, thereby meeting the needs of replacement, charging, maintenance, etc. of the battery 1.

[0079] In addition, it should be noted that the connection between the mounting structure 6 and the vehicle bottom longitudinal beam 200 is not limited, and can be directly connected to the part of the vehicle bottom longitudinal beam 200 that faces the mounting structure 6, or indirectly connected to the connection structure 300 provided on the vehicle bottom longitudinal beam 200 and facing the mounting structure 6.

[0080] In addition, it should be noted that the connection between the mounting structure 6 and the vehicle bottom longitudinal beam 200 is not limited, and can be directly connected to the part of the vehicle bottom longitudinal beam 200 that faces the mounting structure 6, or indirectly connected to the connection structure 300 provided on the vehicle bottom longitudinal beam 200 and facing the mounting structure 6.

[0081] The battery in the related art does not have a mounting structure, and such a battery needs to be first mounted into a battery replacement frame that accommodates the battery, and then the battery replacement frame is locked to the vehicle. Due to the introduction of the battery replacement frame, the required installation space is large, and in the case of limited space under the vehicle, it is difficult to improve the volume energy density of the battery.

[0082] ​​​According to the battery 1 provided in the embodiments of the present application, the mounting structure 6 that can be detachably connected with the vehicle bottom longitudinal beam 200 is arranged on the shell 5 of the battery 1, so that the battery 1 can be mounted to the vehicle bottom longitudinal beam 200 by using the mounting structure 6 to achieve the mounting of the battery 1 to the vehicle 1000, thereby eliminating the battery accommodating frame in the related art, reducing the installation space ratio of the battery accommodating frame, and further increasing the volumetric energy density of the battery 1. Moreover, since the battery accommodating frame is eliminated, the cost is reduced, the vehicle load is reduced, and the battery replacement efficiency is improved. Moreover, the design requirements of the battery volume and bearing capacity of the battery replacement vehicle are reduced, the design difficulty of the battery replacement vehicle is reduced, and the cost is reduced.

[0083] Moreover, the battery in the related art is mounted by using the battery accommodating frame, in order to ensure the energy density of the battery, the height of the battery accommodating frame from the ground is low, and when the ground has a protrusion, the battery accommodating frame is easily impacted, which causes the battery to be damaged. According to the battery 1 provided in the embodiments of the present application, since the battery accommodating frame is eliminated, the ground clearance of the battery 1 is increased, the risk of the battery 1 being damaged due to the ground protrusion is reduced, and the use safety and service life of the battery 1 are improved.

[0084] Moreover, since the battery accommodating frame is eliminated, the ground clearance of the battery 1 is increased, which is beneficial to the battery replacement operation, and in some cases, the battery replacement station 2000 does not need to dig a trench, and the vehicle 1000 does not need to be lifted to achieve the battery replacement. In short, the vehicle lifting or trench digging requirement can be cancelled, so that the site arrangement of the battery replacement station 2000 can be simplified, and the space utilization rate is improved.

[0085] In addition, in the related art, when the battery is mounted by using the battery accommodating frame, a plurality of locking structures are arranged at the outer periphery of the battery accommodating frame, that is, the locking structures are located on the side of the battery away from the vehicle bottom longitudinal beam, the locking structures bear a large torque, and the mounting reliability of the battery is low. According to the battery 1 provided in the embodiments of the present application, since the mounting structure 6 is detachably connected with the vehicle bottom longitudinal beam 200, the mounting structure 6 can be arranged at the position of the shell 5 of the battery 1 close to the vehicle bottom longitudinal beam 200, so that the mounting structure 6 is located between the shell 5 of the battery 1 and the vehicle bottom longitudinal beam 200, that is, the mounting structure 6 is located on the side of the battery 1 close to the vehicle bottom longitudinal beam 200, the mounting structure 6 bears a small torque, and the mounting reliability of the battery 1 is high.

[0086] In addition, in the related art, the locking structures are located on the side of the battery away from the vehicle underbody longitudinal beam, the distance between the locking structures on the two sides of the vehicle underbody longitudinal beam is relatively far, and it is difficult to ensure the relative position accuracy of the multiple locking structures. When the battery is replaced, due to the low relative position accuracy of the multiple locking structures, the multiple locking structures are difficult to quickly and accurately align, resulting in high difficulty in battery replacement and low battery replacement efficiency. According to the battery 1 in the embodiments of the present application, the mounting structure 6 can be arranged on the side of the shell 5 of the battery 1 close to the vehicle underbody longitudinal beam 200. When the mounting structures 6 on the battery 1 are arranged on the two sides of the vehicle underbody longitudinal beam 200, the distance between the mounting structures 6 on the two sides is relatively short, so that the relative position accuracy of the mounting structures 6 on the two sides of the vehicle underbody longitudinal beam 200 can be easily improved, the processing difficulty is reduced, and when the battery 1 is replaced, the relative position accuracy of the mounting structures 6 on the two sides is high, so that the mounting structures 6 on the two sides can be easily aligned, thereby reducing the difficulty of battery replacement and improving the efficiency of battery replacement.

[0087] In the above embodiments, the docking structure 7 that can be docked with the vehicle 1000 is arranged on the shell 5 to realize current conduction or liquid conduction or both. For example, when the docking structure 7 realizes current conduction, current transmission between the vehicle 1000 and the battery 1 can be realized, and the battery 1 can supply power to the vehicle 1000, the vehicle 1000 can control the battery 1, and the like. For example, when the docking structure 7 realizes liquid conduction, heat transfer between the vehicle 1000's coolant system and the battery 1 can be realized, so that the coolant system can be used to adjust the temperature of the battery 1 to improve the working reliability and safety of the battery 1, or the coolant system can be used to absorb the waste heat of the battery 1 to meet the heat source demand of the vehicle 1000's heat pump air conditioning system, and the like, which will not be described here.

[0088] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 6 , the docking structure 7 is arranged on the shell 5 and located on the surface of the shell 5 other than the bottom wall 50a and the peripheral wall 50b.

[0089] Specifically, when the battery 1 is installed for use in the vehicle 1000, the bottom surface of the shell 5 is the bottom wall 50a of the shell 5, the top surface of the shell 5 is the top wall 50c of the shell 5, and the surface of the shell 5 connecting between the top wall 50c of the shell 5 and the bottom wall 50a of the shell 5 and away from the vehicle underbody longitudinal beam 200 is the peripheral wall 50b of the shell 5.

[0090] The bottom wall 50a of the shell 5 can be, but is not limited to, a horizontally arranged planar structure; the top wall 50c of the shell 5 can be, but is not limited to, a horizontally arranged planar structure, for example, can also be a concave structure as shown in the figure; and the outer peripheral wall 50b of the shell 5 can be, but is not limited to, a structure enclosed by a plurality of vertically arranged planar structures in the horizontal direction.

[0091] In the embodiment, the docking structure 7 is neither arranged on the bottom wall 50a of the shell 5 nor arranged on the outer peripheral wall 50b of the shell 5.

[0092] Therefore, since the docking structure 7 is not arranged on the bottom wall 50a of the shell 5, the docking structure 7 can avoid occupying the space below the shell 5, ensure that the ground clearance below the battery 1 is sufficient, reduce the risk of bumping the docking structure 7 due to the protrusion of the ground, and improve the safety of the docking structure 7. Moreover, it is beneficial for battery replacement operation, so that the battery replacement station 2000 does not need to dig a trench, and the vehicle 1000 does not need to be lifted to realize battery replacement.

[0093] Moreover, since the docking structure 7 is not arranged on the outer peripheral wall 50b of the shell 5, the docking structure 7 can avoid occupying the space outside the outer contour of the shell 5, which is beneficial to improve the energy density of the battery 1. Furthermore, since the docking structure 7 is not arranged on the outer peripheral wall, it is not easy to be damaged by external objects, thereby improving the safety of the docking structure 7.

[0094] In addition, since the docking structure 7 is neither arranged on the bottom wall 50a of the shell 5 nor arranged on the outer peripheral wall 50b of the shell 5, the splashed mud and the like are not easy to contact the docking structure 7 during the running of the vehicle 1000, so that the docking structure 7 can be avoided to be corroded, failed, and the like by the mud and the like, to avoid causing docking failure and other problems, and to improve the working reliability of the docking structure 7.

[0095] For example, in some specific embodiments, as shown in Figures 4-7 The top of the shell 5 has a recess 10 adapted to accommodate the vehicle bottom longitudinal beam 200, and the docking structure 7 is located in the recess 10.

[0096] Therefore, the docking structure 7 can be arranged by using the space in the recess 10, so that on the one hand, the docking structure 7 can be protected by the recess 10 to avoid damage by bumping, and the docking structure 7 can be avoided to be corroded and failed by splashed mud during the running of the vehicle 1000, and on the other hand, the docking structure 7 can avoid occupying the space outside the battery 1, thereby being beneficial to improve the energy density of the battery 1. Moreover, it is beneficial for battery replacement operation, so that the battery replacement station 2000 does not need to dig a trench, and the vehicle 1000 does not need to be lifted to realize battery replacement.

[0097] For example, in some specific examples, as shown in Figure 4 and Figure 5As shown, the underbody longitudinal beam 200 can include two longitudinal beams 201 arranged in parallel, both of which extend into the recess 10, and the docking structure 7 can extend into the space between the two longitudinal beams 201, so that the docking structure 7 can more effectively avoid occupying other spaces, and thus the saved space can be used to improve the energy density of the battery 1. This is also conducive to battery swapping operation, so that the battery swapping station 2000 does not need to dig a trench, and the vehicle 1000 does not need to be lifted to realize battery swapping.

[0098] It should be noted that "the recess 10 is adapted to accommodate the underbody longitudinal beam 200" means that at least part of the underbody longitudinal beam 200 extends into the recess 10, rather than the entire underbody longitudinal beam 200 being located in the recess 10. More specifically, the underbody longitudinal beam 200 can be a section extending into the recess 10 in the longitudinal direction, and further can be a local or entire section extending into the recess 10 in the vertical direction.

[0099] It should be noted that the space in the shell 5 directly below the recess 10 can be provided with battery monomers 4 (for example Figure 8 As shown), or can not be provided with battery monomers 4. For example, if battery monomers 4 are provided, the energy density of the battery 1 can be improved; and if battery monomers 4 are not provided, the ground clearance of the battery 1 can be improved, the battery 1 can be protected, and other structural components can be arranged in this space.

[0100] In this embodiment, as shown in Figure 7 and Figure 8 As shown, since the top of the shell 5 has a recess 10 adapted to accommodate the underbody longitudinal beam 200, the space on both sides of the underbody longitudinal beam 200 in the lateral direction can be more effectively used to arrange battery monomers 4, thereby improving the energy density of the battery 1, or the battery monomers 4 originally arranged on the bottom layer of the battery 1 can be transferred to both sides of the underbody longitudinal beam 200 in the lateral direction, thereby improving the ground clearance of the battery 1, ensuring that there is enough space between the bottom of the battery 1 and the ground for battery swapping operation, and since the ground clearance of the battery 1 is improved, the risk of the bottom of the battery 1 being hit or scratched due to ground protrusions and the like can be reduced, improving the safety and service life of the battery 1. Therefore, by arranging the recess 10 on the top of the shell 5, the problem of low space utilization can be effectively solved, which is conducive to improving the safety and reliability of the battery 1 and facilitating battery swapping design.

[0101] It should be noted that, as shown in Figures 6-8As shown, the setting position of the docking structure 7 in the recess 10 is not limited, for example, in some optional examples, the docking structure 7 can be located on the bottom wall 10a of the recess 10. For another example, in some other optional examples, the docking structure 7 can also be located on the side wall 10b of the recess 10. In this way, the docking structure 7 can be protected, and the docking structure 7 can also occupy other space, so that the setting position of the docking structure 7 is flexible. Specifically, when the battery 1 is installed and used in the vehicle 1000, the bottom surface of the vehicle floor longitudinal beam 200 faces the bottom wall 10a of the recess 10, and the outer side surface of the vehicle floor longitudinal beam 200 faces the side wall 10b of the recess 10.

[0102] When the docking structure 7 is located on the bottom wall 10a of the recess 10, the docking structure 7 can extend into the space between the two longitudinal beams 201 of the vehicle floor longitudinal beam 200 in some cases, so that the docking structure 7 can avoid occupying other space, so as to improve the energy density of the battery 1 by saving space, and the docking structure 7 can also avoid being damaged and corroded by splashed mud, so as to improve the safety and reliability of the battery 1.

[0103] When the docking structure 7 is located on the side wall 10b of the recess 10, the space between the two longitudinal beams 201 of the vehicle floor longitudinal beam 200 can be used to accommodate at least part of some battery monomers 4 of the battery 1, so as to improve the energy density of the battery 1. In addition, when the mounting structure 6 and the docking structure 7 are both arranged on the side wall 10b of the recess 10, the distance between the mounting structure 6 and the docking structure 7 can be shortened, so as to easily improve the relative position accuracy of the mounting structure 6 and the docking structure 7. When the mounting structure 6 is docked in place, the docking structure 7 can also be easily and accurately docked, so as to reduce the difficulty of battery replacement, improve the efficiency of battery replacement, and reduce the processing difficulty of the battery 1.

[0104] In some embodiments, the docking structure 7 is arranged on the top wall 50c of the shell 5.

[0105] Specifically, when the battery 1 is installed and used in the vehicle 1000, all the upwardly arranged wall surfaces of the shell 5 are top walls. For example, when the top surface of the shell 5 is a plane, the entire top surface of the shell 5 is a top wall, and in this case, the docking structure 7 can be arranged at any position of the top wall 50c of the shell 5. For another example, when the top of the shell 5 has a recess 10, the transversely two sides of the recess 10 and the upwardly arranged wall surfaces are top walls, and the bottom wall 10a of the recess 10 is also a top wall. In this case, the docking structure 7 can be arranged on the bottom wall of the recess 10 or on the top wall outside the recess 10.

[0106] Therefore, on the one hand, the docking structure 7 is arranged at a relatively high position, which can better avoid the docking structure 7 from being damaged by knocking and corroded by splashed mud, and improve the safety and reliability of the battery 1. On the other hand, the docking structure 7 arranged on the top wall 50c can be arranged in an upward docking direction, so that when the battery 1 is installed upward, the docking structure 7 can be docked in place upward, and when the battery 1 is disassembled, the battery 1 is pulled downward, and the docking structure 7 can be disconnected downward, thereby simplifying the battery replacement operation of the battery 1 and improving the battery replacement efficiency of the battery 1.

[0107] In addition, it is worth noting that when the docking structure 7 is arranged on the top wall 50c of the shell 5, the docking structure 7 is not limited to upward docking, that is, the docking surface of the docking structure 7 is not limited to upward vertical docking. For example, in other embodiments, the docking surface of the docking structure 7 can also be arranged in a horizontal direction to dock in a horizontal direction. Therefore, when the battery 1 is installed, the battery 1 can be first lifted upward, and then the battery 1 is pushed horizontally (for example, the battery 1 is pushed horizontally forward or backward), so that the docking is completed, thereby meeting different design requirements.

[0108] In addition, it is worth noting that when the docking structure 7 is upwardly docked, that is, the docking surface of the docking structure 7 is upwardly docked vertically, the docking structure 7 is not limited to being arranged on the top wall 50c of the shell 5, for example, the docking structure 7 can also be arranged at other positions of the shell 5, for example, the docking structure 7 can be arranged on the outer peripheral wall 50b of the shell 5, and the like, thereby achieving flexible design. In summary, no matter which position of the shell 5 the docking structure 7 is arranged at, as long as the docking surface of the docking structure 7 is upwardly docked vertically, when the battery 1 is installed, the battery 1 is lifted upward, and the docking structure 7 can be docked in place upward, and when the battery 1 is disassembled, the battery 1 is pulled downward, and the docking structure 7 can be disconnected downward, thereby simplifying the battery replacement operation of the battery 1 and improving the battery replacement efficiency of the battery 1. Moreover, the required movement space for docking in this way is small, which can save the space occupied due to docking, and is beneficial to improving the energy density of the battery 1.

[0109] In addition, when the docking surface of the docking structure 7 is arranged in a horizontal direction to dock in a horizontal direction, the docking structure 7 is not limited to being arranged on the top wall 50c of the shell 5, for example, the docking structure 7 can also be arranged at other positions of the shell 5, for example, the docking structure 7 can be arranged on the outer peripheral wall 50b of the shell 5, and the like, thereby achieving flexible design. In summary, no matter which position of the shell 5 the docking structure 7 is arranged at, as long as the docking surface of the docking structure 7 is arranged in a horizontal direction to dock in a horizontal direction, when the battery 1 is installed, the battery 1 can be first lifted upward, and then the battery 1 is pushed horizontally (for example, the battery 1 is pushed horizontally forward or backward), so that the docking is completed, thereby meeting different design requirements, for example, meeting the connection direction requirements of different installation structures 6.

[0110] In some embodiments, as shown in FIG. 1, the docking structure 7 is arranged on the top wall 50c of the shell 5, and the docking surface of the docking structure 7 is arranged in a horizontal direction to dock in a horizontal direction.Figure 6 As shown, the docking structure 7 can be located at the transversely central position of the top of the shell 5. In this way, by arranging the docking structure 7 transversely centrally, the connection of the battery monomer 4 or the temperature adjusting plate 8 and the like in the shell 5 with the docking structure 7 is facilitated, the connection path of the docking structure 7 is simplified, the space required by the connection path is saved, and a larger number or larger volume of battery monomers 4 can be arranged in the shell 5, thereby improving the energy density of the battery 1. In addition, by arranging the docking structure 7 transversely centrally, the center of gravity of the battery 1 in the transverse direction is facilitated to be centered, the stress distribution of each mounting structure 6 on the battery 1 is uniform, the problems such as stress concentration of the mounting structure 6 are improved, and the connection reliability and stability of the battery 1 and the vehicle floor longitudinal beam 200 are improved.

[0111] In some embodiments, as shown in Figure 9 The docking structure 7 can be located at the longitudinally central position of the top of the shell 5. In this way, by arranging the docking structure 7 longitudinally centrally, the connection of the battery monomer 4 or the temperature adjusting plate 8 and the like in the shell 5 with the docking structure 7 is facilitated, the connection path of the docking structure 7 is simplified, the space required by the connection path is saved, and a larger number or larger volume of battery monomers 4 can be arranged in the shell 5, thereby improving the energy density of the battery 1. In addition, by arranging the docking structure 7 longitudinally centrally, the center of gravity of the battery 1 in the longitudinal direction is facilitated to be centered, the stress distribution of each mounting structure 6 on the battery 1 is uniform, the problems such as stress concentration of the mounting structure 6 are improved, and the connection reliability and stability of the battery 1 and the vehicle floor longitudinal beam 200 are improved.

[0112] In some embodiments, as shown in Figure 9 The docking structure 7 includes a plurality of sub-docking portions 71, and the docking functions implemented by the plurality of sub-docking portions 71 are different. For example, in combination with Figure 2 The plurality of sub-docking portions 71 can include at least one of a first sub-docking portion 71a and a second sub-docking portion 71b, the first sub-docking portion 71a is docked with the vehicle 1000 to implement current conduction, and the second sub-docking portion 71b is docked with the vehicle 1000 to implement liquid conduction, thereby enriching the docking function requirements of the battery 1 and the vehicle 1000. For example, in combination with Figure 8 Each sub-docking portion 71 corresponds to at least one docking head 74, and the sub-docking portion 71 can be docked with the vehicle 1000 through the docking head 74.

[0113] When the shell 5 of the battery 1 has a temperature adjusting plate 8 for adjusting the temperature of the battery monomer 4, if the temperature adjusting plate 8 is provided with a liquid path, the second sub-docking portion 71b can be in communication with the liquid path, and the docking of the second sub-docking portion 71b with the vehicle 1000 can be in communication with the vehicle 1000. The refrigerant system is connected to the vehicle 1000 to adjust the temperature of the battery 1 by using the refrigerant system.

[0114] Optionally, the plurality of sub docking portions 71 have the same docking direction. In this way, the battery 1 can be moved along the same direction, and the synchronous docking of the plurality of sub docking portions 71 can be completed, thereby simplifying the docking operation and improving the docking efficiency. Moreover, the docking structure 7 thus designed has a simple structure and is easy to process. For example, the docking faces of the first sub docking portion 71a and the second sub docking portion 71b are both vertically upward and are docked in the vertical direction. For another example, the docking faces of the first sub docking portion 71a and the second sub docking portion 71b are both horizontally and are docked in the horizontal direction.

[0115] In some embodiments, the plurality of sub docking portions 71 are spaced apart along the lateral direction and / or the longitudinal direction of the housing 5. For example, the plurality of sub docking portions 71 can be spaced apart along the lateral direction of the housing 5 but have almost the same position in the longitudinal direction. For another example, the plurality of sub docking portions 71 can be spaced apart along the longitudinal direction of the housing 5 but have almost the same position in the lateral direction. For another example, the plurality of sub docking portions 71 can be spaced apart along the lateral direction of the housing 5 and also be spaced apart along the longitudinal direction of the housing 5.

[0116] In this way, since the plurality of sub docking portions 71 are spaced apart, the docking of each sub docking portion 71 can be ensured to be smooth without interference with each other. Moreover, by spacing apart the plurality of sub docking portions 71 along the lateral direction and / or the longitudinal direction of the housing 5, it is beneficial to meet the requirement that the docking directions of the plurality of sub docking portions 71 are the same, for example, whether the docking is upward at the same time or in the horizontal direction at the same time. In addition, since the plurality of sub docking portions 71 are spaced apart along the lateral direction and / or the longitudinal direction of the housing 5, the plurality of sub docking portions 71 can meet the requirement of being spaced apart while not being spaced apart in the vertical direction, thereby saving the space occupation in the vertical direction and being beneficial to ensure the ground clearance of the bottom of the battery 1.

[0117] In some embodiments, the docking structure 7 and the mounting structure 6 are located on the same side surface of the housing 5. That is, the docking structure 7 and the mounting structure 6 are arranged on the same wall surface of the housing 5, for example, both are arranged on the bottom wall 10a of the recess 10 or both are arranged on the same side wall 10b of the recess 10.

[0118] In this way, the docking structure 7 and the mounting structure 6 are arranged on the same side surface, which is beneficial to processing, reduces the manufacturing difficulty, reduces the tolerance, and shortens the distance between the two, thereby being easy to improve the relative position accuracy of the mounting structure 6 and the docking structure 7. When the mounting structure 6 is docked in place, the docking structure 7 can also be easily and accurately docked to achieve docking, thereby reducing the difficulty of battery replacement, improving the efficiency of battery replacement, and reducing the processing difficulty of the battery 1.

[0119] In some embodiments, as shown in FIG. 1, the mounting structure 6 and the docking structure 7 are arranged on the same side surface of the housing 5, for example, both are arranged on the bottom wall 10a of the recess 10. Figure 6As shown, the docking structure 7 and the mounting structure 6 are located at different side surfaces of the housing 5. That is, the docking structure 7 and the mounting structure 6 are arranged on different wall surfaces of the housing 5, for example, one is arranged on the bottom wall 10a of the recess 10, and the other is arranged on the side wall 10b of the recess 10.

[0120] Therefore, the arrangement of the docking structure 7 and the mounting structure 6 can utilize different spatial positions of the housing 5, avoid mutual interference, and arrange a larger number of docking structures 7 or mounting structures 6, so that the docking structure 7 can be flexibly selected according to its own needs, and the mounting structure 6 can be flexibly selected according to its own needs, to ensure the functional requirements of the docking structure 7 and the mounting structure 6.

[0121] In some embodiments, the docking structure 7 is adjustable relative to the housing 5. Therefore, by adjusting the position of the docking structure 7, different docking positions of the vehicle floor longitudinal beam 200 can be targeted, or different vehicle floor longitudinal beams 200 can be docked, which has strong versatility and wide application range.

[0122] It should be noted that the scheme of the docking structure 7 being adjustable relative to the housing 5 is not limited. For example, the housing 5 has a plurality of first mounting positions, and the docking structure 7 can be selected to be mounted to any first mounting position. For another example, the housing 5 has a first adjusting mechanism, and the docking structure 7 is mounted on the first adjusting mechanism, and the position of the docking structure 7 is movable and adjustable through the driving of the first adjusting mechanism.

[0123] In some embodiments, as shown in Figure 5 , Figure 6 and Figure 9 , the mounting structures 6 on the housing 5 are spaced apart in the transverse direction to be respectively arranged on the transverse sides of the vehicle floor longitudinal beam 200. That is, the housing 5 is provided with the mounting structure 6 corresponding to the position of the transverse side of the vehicle floor longitudinal beam 200 to be connected with the transverse side of the vehicle floor longitudinal beam 200, and the housing 5 is also provided with the mounting structure 6 corresponding to the position of the transverse side of the vehicle floor longitudinal beam 200 to be connected with the transverse side of the vehicle floor longitudinal beam 200. Therefore, the battery 1 can be connected with the transverse sides of the vehicle floor longitudinal beam 200 respectively, so as to improve the installation stability and reliability of the battery 1.

[0124] For example, in some optional examples, as shown in Figure 5 , Figure 6 and Figure 9As shown, the mounting structures 6 on the lateral sides of the underbody longitudinal beam 200 can be symmetrically arranged, i.e. the mounting structure 6 on the lateral side of the underbody longitudinal beam 200 on the shell 5 is symmetrically arranged with the mounting structure 6 on the lateral side of the underbody longitudinal beam 200 on the shell 5. Thus, it is convenient for design and processing, and is beneficial to improve the uniformity of stress distribution, improve the problem of stress concentration of the mounting structure 6, improve the connection reliability of each mounting structure 6, and further improve the installation stability and reliability of the battery 1.

[0125] Of course, the present application is not limited thereto, for example, in some other optional examples, the mounting structures 6 on the lateral sides of the underbody longitudinal beam 200 are arranged in the longitudinal direction, i.e. the mounting structure 6 on the lateral side of the underbody longitudinal beam 200 on the shell 5 is asymmetrically arranged with the mounting structure 6 on the lateral side of the underbody longitudinal beam 200 on the shell 5. Thus, it is beneficial to make the mounting structures 6 fully dispersed, improve the uniformity of stress distribution, improve the problem of stress concentration of the mounting structure 6, and further improve the installation stability and reliability of the battery 1.

[0126] In some embodiments, as shown, Figures 7-9 As shown, the top of the shell 5 has a recess 10, and the recess 10 is adapted to accommodate the underbody longitudinal beam 200, and the mounting structure 6 is located in the recess 10.

[0127] Thus, by arranging the mounting structure 6 in the recess 10, it can be simply and effectively ensured that the mounting structure 6 is located between the shell 5 and the underbody longitudinal beam 200, which is beneficial to the connection of the mounting structure 6 and the underbody longitudinal beam 200, and the mounting structure 6 is arranged by using the space in the recess 10, so that the mounting structure 6 can obtain the protection of the recess 10, avoid the damage of the mounting structure 6 due to collision, improve the installation reliability of the battery 1, and can avoid the problem that the mounting structure 6 is corroded by splashed mud during the operation of the vehicle 1000, so that it cannot be replaced.

[0128] It is worth noting that "the recess 10 is adapted to accommodate the underbody longitudinal beam 200" means that at least part of the underbody longitudinal beam 200 extends into the recess 10, rather than that the underbody longitudinal beam 200 is entirely located in the recess 10. More specifically, the underbody longitudinal beam 200 can extend into the recess 10 in a section in the longitudinal direction, and further can be partially or entirely extended into the recess 10 in the section in the vertical direction.

[0129] In this embodiment, because the top of the housing 5 has a recess 10 suitable for accommodating the vehicle underbody longitudinal beam 200, the space on both sides of the vehicle underbody longitudinal beam 200 can be used more effectively to arrange the battery cells 4, thereby increasing the energy density of the battery 1. Alternatively, the battery cells 4 that originally needed to be arranged at the bottom of the battery 1 can be moved to the lateral sides of the vehicle underbody longitudinal beam 200, thereby increasing the ground clearance of the battery 1. This ensures that there is sufficient space between the bottom of the battery 1 and the ground for battery swapping operations. Furthermore, the increased ground clearance of the battery 1 reduces the risk of damage or scratches to the bottom of the battery 1 due to ground protrusions, improving the safety and lifespan of the battery 1. Therefore, by providing the recess 10 on the top of the housing 5, the problem of low space utilization can be effectively solved, which is beneficial to improving the energy density and ground clearance of the battery 1. This allows the battery swapping station 2000 to achieve battery swapping without digging a trench or raising the vehicle 1000, which is beneficial to battery swapping design.

[0130] It is worth noting that the mounting structure 6 is not limited in its position within the recess 10. For example, in some optional examples, such as... Figure 6 As shown, the mounting structure 6 can be located on at least one of the two transverse sidewalls 10b of the recess 10, that is, the mounting structure 6 can be provided on one sidewall 10b of the recess 10, or the mounting structure 6 can be provided on both sidewalls 10b of the recess 10 respectively. Specifically, when the battery 1 is installed in the vehicle 1000, the bottom surface of the vehicle undercarriage longitudinal beam 200 faces the bottom wall 10a of the recess 10, and the outer surface of the vehicle undercarriage longitudinal beam 200 faces the sidewall 10b of the recess 10.

[0131] Therefore, by placing the mounting structure 6 on the side wall 10b of the recess 10, compared to placing the mounting structure 6 on the bottom wall 10a of the recess 10, the mounting structure 6 can avoid occupying space in the height direction, increase the ground clearance of the battery 1, and ensure that there is enough space between the bottom of the battery 1 and the ground for battery swapping operations. This eliminates the need to dig a trench for the battery swapping station 2000 and to raise the vehicle 1000. Furthermore, the increased ground clearance of the battery 1 reduces the risk of damage or scratches to the bottom of the battery 1 due to ground protrusions, thereby improving the safety and lifespan of the battery 1.

[0132] Furthermore, since the mounting structure 6 is located on the side wall 10b of the recess 10, the force on the battery 1 at the mounting structure 6 can be close to shear stress. However, if the mounting structure 6 is located on the bottom wall 10a of the recess 10, the force on the battery 1 at the mounting structure 6 is basically tensile stress. Therefore, when the mounting structure 6 is located on the side wall 10b of the recess 10, the mounting reliability of the battery 1 can be improved.

[0133] In some embodiments, such as Figure 9As shown, the mounting structure 6 includes a plurality of sub-mounting portions 61 provided on the same side wall 10b of the recess 10. For example, the plurality of sub-mounting portions 61 are provided on the side wall 10b of the lateral side of the recess 10; for another example, the plurality of sub-mounting portions 61 are provided on the side wall 10b of the lateral side of the recess 10, and the plurality of sub-mounting portions 61 are also provided on the side wall 10b of the lateral side of the recess 10.

[0134] Therefore, the dispersion and uniformity of stress distribution are improved, the problem of stress concentration of the sub-mounting portion 61 is solved, the connection reliability of each sub-mounting portion 61 is improved, and the mounting stability and reliability of the battery 1 are improved.

[0135] In some examples, when the mounting structure 6 is provided on the lateral sides of the vehicle floor longitudinal beam 200, and the mounting structures 6 on the lateral sides are symmetrically arranged, the plurality of sub-mounting portions 61 on the side wall 10b of the lateral side of the recess 10 are one-to-one opposite to the plurality of sub-mounting portions 61 on the side wall 10b of the lateral side of the recess 10.

[0136] In some examples, when the mounting structure 6 is provided on the lateral sides of the vehicle floor longitudinal beam 200, and the mounting structures 6 on the lateral sides are symmetrically arranged, the plurality of sub-mounting portions 61 on the side wall 10b of the lateral side of the recess 10 are one-to-one opposite to the plurality of sub-mounting portions 61 on the side wall 10b of the lateral side of the recess 10.

[0137] In some examples, when the mounting structure 6 is provided on the lateral sides of the vehicle floor longitudinal beam 200, and the mounting structures 6 on the lateral sides are symmetrically arranged, the plurality of sub-mounting portions 61 on the side wall 10b of the lateral side of the recess 10 are one-to-one opposite to the plurality of sub-mounting portions 61 on the side wall 10b of the lateral side of the recess 10.

[0138] Alternatively, N can be 2 or 3. Therefore, since the number of sub-mounting portions 61 is relatively small, the relative position accuracy of the plurality of sub-mounting portions 61 can be easily controlled, the alignment and mounting of each sub-mounting portion 61 and the vehicle floor longitudinal beam 200 can be easily achieved, the installation difficulty is reduced, and the installation efficiency is improved.

[0139] It is worth noting that the number N can also be designed in relation to the longitudinal dimension L1 of the battery 1, that is, when the longitudinal dimension L1 of the battery 1 is large, the number N can be designed to be large, and when the longitudinal dimension L1 of the battery 1 is small, the number N can be designed to be small. Therefore, the number of sub-mounting portions 61 can be sufficient and not too many, on the one hand, the connection reliability of the battery 1 can be ensured, and on the other hand, the relative position accuracy of the plurality of sub-mounting portions 61 can be ensured, which is beneficial to reduce the processing difficulty and facilitate assembly.

[0140] Optionally, the plurality of sub-mounting portions 61 on the same side wall 10b of the recess 10 are longitudinally spaced. Thus, there is sufficient space in the longitudinal direction to ensure the spacing between adjacent sub-mounting portions 61, and when the battery 1 is vertically lifted upwards to achieve the connection of the plurality of sub-mounting portions 61 with the vehicle floor longitudinal beam 200, the longitudinally spaced plurality of sub-mounting portions 61 do not interfere with each other, and flexible and diverse design of the sub-mounting portion 61 structure can be achieved. In addition, the longitudinally spaced plurality of sub-mounting portions 61 can disperse the force on the battery 1 at multiple positions in the longitudinal direction, reduce the force on each sub-mounting portion 61, and improve the connection reliability of the battery 1.

[0141] Optionally, the longitudinal dimension L1 of the battery 1 is smaller than the transverse dimension L2 of the battery 1, that is, the transverse dimension L2 of the battery 1 is relatively large, and the longitudinal dimension L1 of the battery 1 is relatively small. When the transverse dimension L2 of the battery 1 cannot exceed the transverse width of the vehicle 1000, the longitudinal dimension L1 of the battery 1 can be ensured not to be too large, and the size of the battery 1 is relatively small. Thus, when the sub-mounting portions 61 on the same side wall are 2-3 and longitudinally spaced on the shell 5, the force on each sub-mounting portion 61 can be better reduced, and the installation reliability of the battery 1 can be ensured. Moreover, due to the relatively small size of the single battery 1, the deformation of the battery 1 can be reduced, which is beneficial to improve the assembly success rate of the battery 1.

[0142] In some embodiments, as shown in Figure 6 The mounting structure 6 is located at a position close to the bottom wall 10a of the recess 10 on the side wall 10b of the recess 10. Thus, it is beneficial to make the vertical position of the mounting structure 6 as central as possible, so that the weight of the battery 1 can be better borne, and the installation reliability and stability of the battery 1 can be improved.

[0143] In some embodiments, as shown in Figure 6 The mounting structure 6 is located at a position close to the bottom wall 10a of the recess 10 on the side wall 10b of the recess 10. Thus, it is beneficial to make the vertical position of the mounting structure 6 as central as possible, so that the weight of the battery 1 can be better borne, and the installation reliability and stability of the battery 1 can be improved.

[0144] In some embodiments, the mounting structure 6 is adjustable in position relative to the shell 5. Thus, by adjusting the position of the mounting structure 6, the mounting structure 6 can be installed on different mounting positions of the vehicle floor longitudinal beam 200, or on different vehicle floor longitudinal beams 200, which has strong universality and wide application range.

[0145] It should be noted that the scheme of the mounting structure 6 being adjustable in position relative to the shell 5 is not limited. For example, the shell 5 has a plurality of second mounting positions, and the mounting structure 6 can be selectively mounted to any second mounting position. For another example, the shell 5 has a second adjusting mechanism, and the mounting structure 6 is mounted on the second adjusting mechanism, and the position of the mounting structure 6 is movable and adjustable through the driving of the second adjusting mechanism.

[0146] In some embodiments, such as Figure 2 As shown, the longitudinal dimension L1 of battery 1 is smaller than the lateral dimension L2 of battery 1, indicating that the lateral dimension L2 of battery 1 is relatively large, while the longitudinal dimension L1 of battery 1 is relatively small. When the lateral dimension L2 of battery 1 cannot exceed the lateral width of vehicle 1000, the longitudinal dimension L1 of battery 1 can be ensured not to be too large, and the size of battery 1 is relatively small. This is beneficial to improving the installation reliability of battery 1 and facilitating its installation. For example, when there are 2-3 sub-mounting parts 61 on the same side wall and they are arranged longitudinally at intervals, the stress on each sub-mounting part 61 can be reduced, ensuring the installation reliability of battery 1. Moreover, since the size of a single battery 1 is relatively small, the deformation of battery 1 can be reduced, which is beneficial to improving the assembly success rate of battery 1.

[0147] Furthermore, multiple batteries 1 (e.g.,) can be installed at the bottom of the vehicle 1000. Figure 10 As shown in the diagram, multiple batteries 1 are configured to be individually swappable relative to the vehicle 1000. This allows for the matching of the appropriate number of batteries 1 based on different application scenarios, mileage, and vehicle 1000 configurations, improving the flexibility of battery swapping and ensuring compatibility with different vehicle models and application scenarios. Furthermore, since it is not necessary to match a single type of battery pack to a specific vehicle model, the adaptability of the battery swapping station is improved, thereby reducing the number of swapping stations, increasing the distance between adjacent swapping stations, and lowering investment costs.

[0148] For example, large heavy trucks can use six batteries¹, while tractor units only need three batteries¹, and small trucks only need two batteries¹. Range requirements also need to be considered; for example, a tractor unit using three batteries¹ can travel 300-500 kilometers, but if a range of 300-500 kilometers is not required, then using two batteries¹ or one battery¹ can be considered.

[0149] Furthermore, it eliminates the need to install all batteries 1 into the vehicle 1000, reducing the load on the vehicle 1000. Also, since each battery 1 can be replaced individually, batteries 1 that have been deeply discharged can be removed, avoiding the waste of battery power caused by replacing batteries 1 before they are fully discharged.

[0150] Furthermore, compared to a single large battery pack solution, when multiple relatively small batteries 1 are used in combination, the battery swapping efficiency is higher because it is not necessary to replace all batteries 1 each time. This can significantly improve the throughput of a battery swapping station 2000 in the same space.

[0151] In some embodiments, such as Figure 3As shown, the shell 5 comprises a shell body 53 and a shell cover 54, the shell body 53 is an integral piece and has an opening on the shell body 53, the shell cover 54 covers the opening, one of the mounting structure 6 and the mating structure 7 is arranged on the shell body 53, and the other of the mounting structure 6 and the mating structure 7 is arranged on the shell cover 54. For example, the mounting structure 6 is arranged on the shell body 53, and the mating structure 7 is arranged on the shell cover 54. For another example, the mounting structure 6 is arranged on the shell cover 54, and the mating structure 7 is arranged on the shell body 53.

[0152] Therefore, during installation, the battery monomer 4 can be loaded into the shell body 53 through the opening, and then the opening is covered by the shell cover 54, thereby facilitating the assembly of the battery 1. Moreover, since one of the mounting structure 6 and the mating structure 7 is arranged on the shell body 53, and the other of the mounting structure 6 and the mating structure 7 is arranged on the shell cover 54, the relative positions of the mounting structure 6 and the mating structure 7 can be flexibly designed.

[0153] In addition, it should be noted that although one of the mounting structure 6 and the mating structure 7 is arranged on the shell body 53, and the other of the mounting structure 6 and the mating structure 7 is arranged on the shell cover 54, based on the flexible design of the structure of the shell body 53 and the shell cover 54, it can be selected to satisfy that the mating structure 7 and the mounting structure 6 are located on the same side surface of the shell 5, or it can be selected to satisfy that the mating structure 7 and the mounting structure 6 are located on different side surfaces of the shell 5.

[0154] For example, when the side wall 10b of the recess 10 is defined by the shell body 53, and the bottom wall 10a of the recess 10 is defined by the shell cover 54, and the mating structure 7 is arranged on the bottom wall 10a of the recess 10, and the mounting structure 6 is arranged on the side wall 10b of the recess 10, although the mating structure 7 is arranged on the shell cover 54, and the mounting structure 6 is arranged on the shell body 53, the mating structure 7 and the mounting structure 6 are located on different side surfaces of the shell 5.

[0155] Of course, the present application is not limited to this, for example, in some other embodiments, the shell 5 comprises a shell body 53 and a shell cover 54, the shell body 53 is an integral piece and has an opening on the shell body 53, the shell cover 54 covers the opening, and the mounting structure 6 and the mating structure 7 are both arranged on the shell body 53 or both arranged on the shell cover 54. For example, the mounting structure 6 and the mating structure 7 are both arranged on the shell body 53, and for another example, the mounting structure 6 and the mating structure 7 are both arranged on the shell cover 54.

[0156] Therefore, when installing, the battery monomer 4 can be loaded into the shell body 53 through the opening, and then the shell cover 54 is used to cover the opening, thereby facilitating the assembly of the battery 1. Moreover, the mounting structure 6 and the docking structure 7 are both arranged on the shell body 53 or both arranged on the shell cover 54, so that the relative position tolerance of the mounting structure 6 and the docking structure 7 can be smaller, and the relative position accuracy of the mounting structure 6 and the docking structure 7 can be easily improved. When the mounting structure 6 is docked in place, the docking structure 7 can also be easily and accurately docked, thereby reducing the difficulty of battery replacement, improving the efficiency of battery replacement, and reducing the processing difficulty of the battery 1.

[0157] In addition, it should be noted that although the mounting structure 6 and the docking structure 7 are both arranged on the shell body 53 or both arranged on the shell cover 54, based on the flexible structure design of the shell body 53 and the shell cover 54, the docking structure 7 and the mounting structure 6 can be located on the same side surface of the shell 5, or the docking structure 7 and the mounting structure 6 can be located on different side surfaces of the shell 5.

[0158] For example, the side wall 10b and the bottom wall 10a of the recess 10 are both defined by the shell cover 54. When the docking structure 7 is arranged on the bottom wall 10a of the recess 10, and the mounting structure 6 is arranged on the side wall 10b of the recess 10, although the docking structure 7 and the mounting structure 6 are both arranged on the shell cover 54, the docking structure 7 and the mounting structure 6 are located on different side surfaces of the shell 5.

[0159] It should be noted that the structure and shape of the shell body 53 are not limited, and can be specifically designed according to the shape of the battery 1. The opening position and number on the shell body 53 are not limited, and can be designed according to the actual situation. For example, the opening can be arranged on the longitudinal side, or the vertical top side, or the vertical bottom side, or the horizontal side of the shell body 53. The shape and number of the shell cover 54 are also not limited, and can be designed according to the opening. At least one shell cover 54 can be arranged corresponding to one opening. For example, in some embodiments of the present application, the top of the shell body 53 has an opening, and the shell cover 54 is an integral piece, or multiple shell covers are arranged on the opening at the top of the shell body 53. Therefore, the design is simple.

[0160] In some embodiments, as shown in Figure 3 , Figure 6 and Figure 8 , the shell 5 can include a first shell part 51 and two second shell parts 52 located on the transverse two sides of the first shell part 51. The battery monomer 4 is arranged in the first shell part 51. The battery monomer 4 can be arranged in the second shell part 52. The battery monomer 4 can also not be arranged in the second shell part 52. The top wall of each second shell part 52 is higher than the top wall of the first shell part 51. The recess 10 of any of the above embodiments can be defined between the top wall of the first shell part 51 and the side wall of the two second shell parts 52. In combination with Figure 4 and Figure 5 , the longitudinal two sides of the recess 10 are open, and the longitudinal beam 200 of the vehicle bottom is adapted to be arranged in the recess 10 in the longitudinal direction.

[0161] Therefore, since the top of the shell 5 has the recess 10 suitable for accommodating the vehicle floor longitudinal beam 200, the space on both sides of the vehicle floor longitudinal beam 200 in the transverse direction can be effectively utilized to arrange the battery monomer 4, thereby improving the energy density of the battery 1, or the battery monomer 4 originally arranged at the bottom layer of the battery 1 can be transferred to both sides of the vehicle floor longitudinal beam 200 in the transverse direction, thereby the ground clearance of the battery 1 can be improved, and enough space between the bottom of the battery 1 and the ground can be reserved for battery replacement operation, and since the ground clearance of the battery 1 is improved, the risk of bumping and scratching the bottom of the battery 1 due to ground protrusions and the like can be reduced, and the use safety and service life of the battery 1 are improved. Therefore, by arranging the recess 10 on the top of the shell 5, the problem of low space utilization can be effectively solved, which is beneficial to improve the safety and reliability of the battery 1, and is beneficial to the battery replacement design.

[0162] In some embodiments, as shown in Figure 3 and Figure 6 The battery module 3 includes one or more battery monomers 4, and a plurality of battery modules 3 are arranged side by side to form a battery layer 2. One layer of battery layers 2 or a plurality of layers of battery layers 2 arranged in the vertical direction are arranged in the first shell part 51, and one layer of battery layers 2 or a plurality of layers of battery layers 2 arranged in the vertical direction are arranged in the second shell part 52.

[0163] In the above embodiments, a plurality of battery modules 3 are arranged in the horizontal direction to form a battery layer 2, for example, a plurality of battery modules 3 are arranged in the transverse direction, or a plurality of battery modules 3 are arranged in the longitudinal direction, or a plurality of battery modules 3 are arranged in multiple rows and multiple columns in the transverse and longitudinal directions, and the like. In addition, a plurality of battery modules 3 can be connected in series, or connected in parallel, or connected in a hybrid manner, and the like.

[0164] Therefore, by arranging the battery monomers 4 in groups, the assembly efficiency of the battery 1 can be improved, and the electrical connection can be simplified, and the like. In addition, since one layer of battery layers 2 or a plurality of layers of battery layers 2 arranged in the vertical direction are arranged in the first shell part 51, and one layer of battery layers 2 or a plurality of layers of battery layers 2 arranged in the vertical direction are arranged in the second shell part 52, the total height of the battery monomers 4 contained in the second shell part 52 can be greater than the total height of the battery monomers 4 contained in the first shell part 51 by controlling the number of layers or the layer height, or combining battery layers 2 with different layer heights, thereby the space can be fully utilized, and the energy density of the battery 1 can be improved.

[0165] In some embodiments, the number of layers of the battery layers 2 in the second shell portion 52 is greater than the number of layers of the battery layers 2 in the first shell portion 51. In this way, when the height of each battery layer 2 in the second shell portion 52 is the same as or similar to the height of each battery layer 2 in the first shell portion 51, the total height of the battery monomers 4 accommodated in the second shell portion 52 can be greater than the total height of the battery monomers 4 accommodated in the first shell portion 51 by controlling the number of layers, thereby facilitating the full use of space and improving the energy density of the battery 1.

[0166] Alternatively, the height of each battery layer 2 in the second shell portion 52 is the same as the height of each battery layer 2 in the first shell portion 51. In this way, since the height of each battery layer 2 in the second shell portion 52 is the same as the height of each battery layer 2 in the first shell portion 51, the positions of the battery modules 3 can be interchanged, reducing the assembly difficulty. Moreover, the same specification of battery monomers 4 can be used to combine each battery module 3, simplifying the overall design and reducing the cost.

[0167] Alternatively, the height of at least one battery layer 2 in the second shell portion 52 is different from the height of at least one battery layer 2 in the first shell portion 51. For example, the height of at least one battery layer 2 in the second shell portion 52 is greater than the height of at least one battery layer 2 in the first shell portion 51. For another example, the height of at least one battery layer 2 in the second shell portion 52 is less than the height of at least one battery layer 2 in the first shell portion 51. In this way, flexible design can be achieved to meet different design requirements.

[0168] Specifically, the height of the battery layer 2 refers to the vertical dimension of the battery layer 2, which is determined according to the placement manner of the battery modules 3 included in the battery layer 2. For example, when the length direction of the battery module 3 is arranged vertically, the length of the battery module 3 is the height of the battery layer 2. For another example, when the thickness direction of the battery module 3 is arranged vertically, the thickness of the battery module 3 is the height of the battery layer 2. For another example, when the width direction of the battery module 3 is arranged vertically, the width of the battery module 3 is the height of the battery layer 2.

[0169] Therefore, when the heights of the two battery layers 2 are different, there can be various ways. For example, the placement manner of the battery modules 3 included in the two battery layers 2 can be the same but the specifications are different, such as the length direction of the two battery modules 3 is longitudinal, the width direction is horizontal, and the thickness direction is vertical, but the thickness dimensions of the two battery modules 3 are different. For another example, the placement manner of the battery modules 3 included in the two battery layers 2 can be different but the specifications are the same, such as the length, width, and height dimensions of the two battery modules 3 are the same respectively, but the length of one battery module 3 is vertical, and the thickness of the other battery module 3 is vertical, and so on.

[0170] In some embodiments, the battery layer 2 in the first shell part 51 is one layer, the battery layer 2 in the second shell part 52 is two layers, the height of the lower battery layer 2 in the second shell part 52 is the same as the height of the battery layer 2 in the first shell part 51, and the height of the upper battery layer 2 in the second shell part 52 is greater than or equal to the height of the lower battery layer 2 in the second shell part 52.

[0171] In the above embodiments, the height of the lower battery layer 2 in the second shell part 52 being the same as the height of the battery layer 2 in the first shell part 51 and being arranged in a flush manner refers to that the bottom surface of the lower battery layer 2 in the second shell part 52 is flush with the bottom surface of the battery layer 2 in the first shell part 51, and the top surface of the lower battery layer 2 in the second shell part 52 is flush with the top surface of the battery layer 2 in the first shell part 51.

[0172] In this way, the space in the shell 5 can be fully utilized, and the arrangement of the battery module 3 can be simplified, for example, the battery module 3 of the lower battery layer 2 in the second shell part 52 can be interchangeably used with the battery module 3 of the battery layer 2 in the first shell part 51, and the like. Moreover, the total height of the battery monomer 4 accommodated in the second shell part 52 can be effectively ensured to be greater than the total height of the battery monomer 4 accommodated in the first shell part 51, thereby facilitating the full utilization of the space and improving the energy density of the battery 1. In addition, the ground clearance of the battery 1 can also be ensured to be sufficient, thereby facilitating battery replacement and protecting the battery 1 from being bumped.

[0173] In some embodiments, the second shell part 52 is provided with multiple battery layers 2, and the arrangement direction of the multiple battery modules 3 in at least two battery layers 2 is perpendicular. For example, the multiple battery modules 3 in at least one battery layer 2 in the second shell part 52 are arranged in sequence along the transverse direction, and meanwhile, the multiple battery modules 3 in at least one battery layer 2 in the second shell part 52 are arranged in sequence along the longitudinal direction.

[0174] Or in some other embodiments, the second shell part 52 is provided with multiple battery layers 2, and the arrangement direction of the multiple battery modules 3 in each battery layer 2 is consistent. For example, the multiple battery modules 3 in each battery layer 2 in the second shell part 52 are arranged in sequence along the transverse direction. For another example, the multiple battery modules 3 in each battery layer 2 in the second shell part 52 are arranged in sequence along the longitudinal direction. In this way, the flexible arrangement of the battery module 3 in the second shell part 52 can be realized, thereby meeting different actual needs.

[0175] In some embodiments, the first shell part 51 is provided with one layer of battery layers 2, and the arrangement direction of the plurality of battery modules 3 in the battery layer 2 in the first shell part 51 is consistent with the arrangement direction of the plurality of battery modules 3 in at least one battery layer 2 in the second shell part 52. For example, the plurality of battery modules 3 in the battery layer 2 in the first shell part 51 are arranged in sequence along the transverse direction, and the plurality of battery modules 3 in at least one battery layer 2 in the second shell part 52 are also arranged in sequence along the transverse direction. For another example, the plurality of battery modules 3 in the battery layer 2 in the first shell part 51 are arranged in sequence along the longitudinal direction, and the plurality of battery modules 3 in at least one battery layer 2 in the second shell part 52 are also arranged in sequence along the longitudinal direction.

[0176] Or in some other embodiments, the first shell part 51 is provided with one layer of battery layers 2, and the arrangement direction of the plurality of battery modules 3 in the battery layer 2 in the first shell part 51 is perpendicular to the arrangement direction of the plurality of battery modules 3 in at least one battery layer 2 in the second shell part 52. For example, the plurality of battery modules 3 in the battery layer 2 in the first shell part 51 are arranged in sequence along the transverse direction, and the plurality of battery modules 3 in at least one battery layer 2 in the second shell part 52 are arranged in sequence along the longitudinal direction. For another example, the plurality of battery modules 3 in the battery layer 2 in the first shell part 51 are arranged in sequence along the longitudinal direction, and the plurality of battery modules 3 in at least one battery layer 2 in the second shell part 52 are arranged in sequence along the transverse direction.

[0177] In this way, the flexible arrangement of the battery modules 3 in the first shell part 51 and the second shell part 52 can be realized, and different actual needs can be met.

[0178] In some embodiments, the plurality of battery modules 3 in at least one layer of battery layers 2 are arranged along the longitudinal direction, and the length direction of each battery module 3 extends along the transverse direction. In this way, the space can be fully utilized, and the battery modules 3 are convenient to arrange to form the battery layer 2.

[0179] In some embodiments, the plurality of battery modules 3 in at least one layer of battery layers 2 are arranged along the transverse direction, and the length direction of each battery module 3 extends along the longitudinal direction. In this way, the space can be fully utilized, and the battery modules 3 are convenient to arrange to form the battery layer 2.

[0180] In this way, the flexible design of the battery layer 2 can be realized, and different actual needs can be met.

[0181] In some embodiments, the plurality of battery cells 4 included in at least one battery module 3 are arranged along one of the length direction, the width direction, and the thickness direction of the battery module 3.

[0182] For example, at least one battery module 3 may include a plurality of battery cells 4 arranged along the length of the battery module 3. Another example is that at least one battery module 3 may include a plurality of battery cells 4 arranged along the width of the battery module 3. Yet another example is that at least one battery module 3 may include a plurality of battery cells 4 arranged along the thickness of the battery module 3.

[0183] This allows for flexible design of battery module 3 to meet different practical needs.

[0184] In some embodiments, such as Figure 3 and Figure 11 As shown, the battery 1 includes a temperature regulating plate 8, which includes at least one of a first regulating plate 81, a second regulating plate 82, a third regulating plate 83, a fourth regulating plate 84, and a fifth regulating plate 85. The first regulating plate 81 is disposed between two vertically adjacent battery layers 2, the second regulating plate 82 is disposed at the bottom of the bottom battery layer 2, the third regulating plate 83 is disposed at the top of the top battery layer 2, the fourth regulating plate 84 is disposed between two adjacent battery modules 3 in the same battery layer 2, and the fifth regulating plate 85 is disposed between two adjacent battery cells 4 in the same battery module 3. Therefore, by arranging the temperature regulating plate 8 in at least one form, the temperature of the battery cells 4 can be regulated, allowing the battery 1 to operate at a suitable temperature, improving the reliability and lifespan of the battery 1, and increasing the energy efficiency of the battery 1.

[0185] In some embodiments, such as Figure 6 and Figure 11 As shown, the battery 1 includes a temperature regulating plate 8, which is provided in both the first housing 51 and the second housing 52. Therefore, the battery cells 4 in the first housing 51 and the second housing 52 can both achieve temperature regulation, allowing the battery 1 to operate at a suitable temperature, thereby improving the reliability and lifespan of the battery 1, and increasing its energy efficiency.

[0186] For example, in some specific examples, such as Figure 6 and Figure 11 As shown, the temperature regulating plate 8 includes a common horizontal plate 86, a portion of which is located within the first housing 51, and the remainder of which is located within the second housing 52. This simplifies the design and assembly of the temperature regulating plate 8.

[0187] In some embodiments, such as Figure 8 As shown, the docking structure 7 is located outside the housing 5. In other words, the docking structure 7 can be set entirely outside the housing 5. This avoids the docking structure 7 occupying the space inside the housing 5 for storing the battery cell 4, thereby increasing the energy density of the battery 1.

[0188] For example, in some specific examples, as shown in Figure 6 and Figure 8 The docking structure 7 can include a box body 72, a docking body 73 and a docking head 74. The box body 72 is arranged above the bottom wall 10a of the recess 10. The docking body 73 is arranged in the box body 72. The docking head 74 is arranged outside the box body 72 and connected with the docking body 73. The docking body 73 is connected with the circuit and / or liquid path in the shell 5. Thus, the docking structure 7 is simple, easy to process and install, and can effectively avoid occupying the space in the shell 5 for storing the battery monomer 4, thereby improving the energy density of the battery 1.

[0189] In the above embodiments, the docking body 73 is not limited. When used to realize liquid conduction, the docking body 73 can include a pipeline, or a pipeline and a control valve, etc. When used to realize current conduction, the docking body 73 can include a wire, or a wire and a circuit board, etc., which are not described herein.

[0190] In the above embodiments, the box body 72 can have a bottom wall or not, which can be set according to actual conditions. In addition, the position of the shell 5 corresponding to the bottom wall of the box body 72 (for example, at least part of the bottom wall 10a of the recess 10) can be hollow or solid structure, which can be set according to actual conditions.

[0191] In some embodiments, the shell 5 of the battery 1 can be made of high-strength material to ensure that the mounting structure 6 arranged on the shell can ensure the connection reliability with the vehicle floor longitudinal beam 200. For example, high-strength steel roll-shaped section bar, etc.

[0192] Next, the vehicle 1000 according to the embodiments of the present application is described with reference to the accompanying drawings.

[0193] As shown in Figure 1 and Figure 12 The vehicle 1000 can include a vehicle floor longitudinal beam 200 and a battery 1 according to any embodiment of the present application.

[0194] In some embodiments, as shown in Figure 4 and Figure 5 The vehicle floor longitudinal beam 200 has a connecting structure 300. The mounting structure 6 is detachably connected with the connecting structure 300. At least one of the mounting structure 6 and the connecting structure 300 is a locking structure. For example, the mounting structure 6 is a locking structure. For another example, the connecting structure 300 is a locking structure. For another example, the mounting structure 6 and the connecting structure 300 are both locking structures.

[0195] The locking structure has a locked state and an unlocked state. In the locked state, the mounting structure 6 and the connecting structure 300 are in the locked state and cannot be separated, and the battery 1 is in a firmly mounted state. In the unlocked state, the mounting structure 6 and the connecting structure 300 are in the unlocked state and can be separated, and the battery 1 can be removed from the vehicle 1000.

[0196] Therefore, by setting at least one of the mounting structure 6 and the connecting structure 300 as a locking structure, the firm installation of the battery 1 is facilitated, and the requirement of replacing the battery 1 is met. Specifically, the specific type of the locking structure is not limited, for example, it can include a screw, a padlock, etc.

[0197] In some embodiments, as shown in Figure 12 The unlocking position of the locking structure is located on the longitudinal outer side of the battery 1. For example, the unlocking position is located in front of the battery 1 or behind the battery 1, for example, between two adjacent batteries 1 in the longitudinal direction. Therefore, since the unlocking position of the locking structure is located on the longitudinal outer side of the battery 1, the unlocking position is not blocked by the battery 1, so that the unlocking operation and locking observation of the locking structure can be conveniently performed.

[0198] Moreover, it is not necessary to punch a hole vertically from the bottom of the battery 1, so that the unlocking member extends vertically into the hole to reach the locking structure for unlocking, thereby avoiding occupying the space in the battery 1 due to punching, and further improving the energy density of the battery 1. Moreover, the problem of sealing difficulty of the battery 1 caused by punching is avoided, which is beneficial to the processing and design of the battery 1.

[0199] For example, when the battery 1 is multiple, if the unlocking position of the locking structure is located on the longitudinal outer side of the battery 1, the gap between two adjacent batteries 1 can be 30mm or more, thereby facilitating unlocking.

[0200] In some embodiments, as shown in Figure 10 and Figure 11 The vehicle bottom longitudinal beam 200 includes two longitudinal beams 201 arranged in parallel, and the docking structure 7 is arranged on the top of the battery 1 and extends into the space between the two longitudinal beams 201. Therefore, the docking structure 7 can avoid occupying other space, so as to utilize the saved space to improve the energy density of the battery 1, and further avoid the docking structure 7 from being damaged by knocking and corroded by splashed mud, thereby improving the safety and reliability of the battery 1.

[0201] In some embodiments, as shown in Figure 1 and Figure 2As shown, the vertical distance between the bottom surface of the wheels of the vehicle 1000 and the bottom surface of the battery 1 is H1, the vertical distance between the bottom surface of the wheels of the vehicle 1000 and the bottom surface of the vehicle floor longitudinal beam 200 is H2, the height of the battery replacement transport vehicle is H4, and the vertical height of the battery 1 is L3, wherein H2≥L3+H4, and H1>H4, for example, H2=700mm, L3=600mm, H4=100mm, and H1≥300mm. Thus, the battery replacement station 2000 does not need to dig a trench, and the battery replacement can be realized without lifting the vehicle 1000, and the height of the battery 1 in the vertical direction can make full use of the space and keep a safe distance from the ground.

[0202] In some embodiments, as shown in Figure 1 and Figure 2 The longitudinal dimension L1 of the battery 1 is smaller than the transverse dimension L2 of the battery 1, which means that the transverse dimension L2 of the battery 1 is relatively large, and the longitudinal dimension L1 of the battery 1 is relatively small. When the transverse dimension L2 of the battery 1 cannot exceed the transverse width of the vehicle 1000, the longitudinal dimension L1 of the battery 1 can be ensured not to be too large, and the size of the battery 1 is relatively small, thereby facilitating the installation reliability of the battery 1 and the installation of the battery 1. For example, when the sub-mounting portions 61 on the same side wall are 2-3 and are arranged in the longitudinal direction, the stress of each sub-mounting portion 61 can be reduced, and the installation reliability of the battery 1 can be ensured. Moreover, due to the relatively small size of the single battery 1, the deformation of the battery 1 can be reduced, and the assembly success rate of the battery 1 can be improved. Hereinafter, the battery replacement station 2000 according to the embodiments of the present application is described with reference to the accompanying drawings.

[0203] As shown in Figure 1 and Figure 13 The battery replacement station 2000 is used for replacing the battery 1 of the vehicle 1000 according to any embodiment of the present application.

[0204] In some embodiments, the battery replacement station 2000 comprises a battery replacement area 600, and the vehicle 1000 is adapted to replace the battery 1 in the battery replacement area 600. The battery replacement area 600 comprises a first area 601 and a second area 602. The first area 601 is adapted to be located directly below the battery 1, and the second area 602 is used to support the front wheels 400 and the rear wheels 500 adjacent to the battery 1. The ground surface of the first area 601 and the second area 602 is flush.

[0205] Since the ground clearance of the battery 1 according to some embodiments of the present application can be improved, the battery replacement station 2000 can cancel the requirement of lifting the whole vehicle or digging a trench, thereby simplifying the site arrangement of the battery replacement station 2000 and improving the space utilization.

[0206] Optionally, the ground of the battery replacement area 600 is a plane as a whole, thereby reducing the construction difficulty of the battery swap station 2000 and facilitating the reduction of the construction cost of the battery swap station 2000.

[0207] Hereinafter, with reference to the accompanying drawings, a battery 1 and a battery replacement method applied to a vehicle 1000 according to an embodiment of the present application are described. Figures 1-13

[0208] The vehicle 1000 is provided with a plurality of batteries 1 arranged along the length direction of the vehicle bottom longitudinal beam 200, each battery 1 being detachable from the vehicle bottom longitudinal beam 200, and the top of each battery 1 is provided with a recess 10 for accommodating the vehicle bottom longitudinal beam 200, so that the battery 1 can utilize the space on the lateral sides and below the vehicle bottom longitudinal beam 200, thereby ensuring the energy density of the battery 1 and increasing the ground clearance of the battery 1.

[0209] The batteries 1 arranged on the lateral sides of the vehicle bottom longitudinal beam 200 are each provided with two battery layers 2, each battery layer 2 comprising a plurality of battery modules 3 arranged side by side, and each battery module 3 comprising a plurality of battery monomers 4 arranged side by side, so that the space on the lateral sides of the vehicle bottom longitudinal beam 200 is fully and effectively utilized. The battery 1 arranged below the vehicle bottom longitudinal beam 200 is provided with one battery layer 2 comprising a plurality of battery modules 3 arranged side by side, and each battery module 3 comprising a plurality of battery monomers 4 arranged side by side, so that the space below the vehicle bottom longitudinal beam 200 is fully utilized, and at the same time, the sufficient space between the bottom surface of the battery 1 and the ground is effectively ensured, on the one hand, the convex surface of the bottom surface of the battery 1 and the ground can be avoided, thereby effectively protecting the battery 1, and on the other hand, sufficient space for battery replacement is reserved, so that the battery swap station 2000 does not need to dig a trench, and the vehicle 1000 does not need to be lifted to realize battery replacement, thereby simplifying the site arrangement of the battery swap station 2000 and improving the space utilization.

[0210] Specifically, the mounting structure 6 is arranged on each of the lateral walls 10b of the recess 10, each mounting structure 6 comprising 2-3 sub-mounting portions 61 arranged in the longitudinal direction, and the lateral sides of the vehicle bottom longitudinal beam 200 are provided with a connecting structure 300 corresponding to each mounting structure 6, one of the sub-mounting portion 61 and the connecting structure 300 being a mounting pin, and the other being a battery replacement lock, when the battery 1 is replaced, the battery 1 is pushed upward, the mounting pin is clamped into the battery replacement lock, and the installation of the battery 1 to the vehicle bottom longitudinal beam 200 is completed. Since the vehicle bottom longitudinal beam 200 is provided with a plurality of batteries 1, each battery 1 has a relatively small size, which not only improves the installation reliability of each battery 1, but also facilitates the design of the battery replacement of each battery 1.

[0211] ​In the related art, when the battery is installed on the vehicle, the battery pack is first pre-installed on the battery replacement frame, and then the entire battery replacement frame is fixed to the vehicle chassis. Such installation method mainly has the following problems.

[0212] Firstly, since the battery pack is pre-installed on the battery replacement frame, the entire battery replacement unit is large and heavy, and the battery replacement station needs to dig a trench or lift the vehicle, and the battery replacement transport vehicle needs to be larger, heavier, more complex in design and higher in cost.

[0213] The battery 1 of the embodiment of the application can be installed on the vehicle bottom longitudinal beam 200 through the self-mounting structure 6, thereby the battery replacement frame can be omitted, the battery replacement cost is reduced, the battery replacement efficiency is improved, the ground clearance of the battery 1 can be increased, the entire vehicle does not need to be lifted or a trench needs to be dug for the battery replacement transport vehicle to pass through, and the site configuration difficulty of the battery replacement station 2000 is reduced. Moreover, the design difficulty of the battery replacement transport vehicle can be reduced, and the cost is reduced.

[0214] Secondly, the battery replacement lock attachment points on the battery replacement frame are located on the outer peripheral wall of the battery replacement frame, the span between the plurality of battery replacement lock attachment points is large, the deviation between the plurality of battery replacement lock attachment points is large, the lock attachment time is lengthened during battery replacement, the battery replacement lock attachment success rate is reduced, and the battery replacement efficiency is restricted. Moreover, the torque borne by the battery replacement lock attachment point is large, the strength requirement of the fast replacement lock is extremely high, and the installation reliability of the battery is low.

[0215] The battery 1 of the embodiment of the application can be installed on the vehicle bottom longitudinal beam 200 through the self-mounting structure 6, and the mounting structure 6 faces the vehicle bottom longitudinal beam 200, thereby the deviation between the lock attachment points can be reduced, the lock attachment time is shortened during battery replacement, the battery replacement lock attachment success rate is improved, and the battery replacement efficiency is improved. Moreover, the torque borne by the mounting structure 6 is small, the installation reliability of the battery 1 is high, and the strength requirement of the mounting pin to the battery replacement lock is low.

[0216] Thirdly, because the battery packs are integrated together as a whole pack, a larger battery replacement frame is needed to bear the stress, and therefore the space occupied by the battery replacement frame is larger, thereby the battery pack capacity cannot be large, the distance between the battery replacement stations is limited, the number of the battery replacement stations is increased, and the cost is increased.

[0217] The battery 1 of the embodiment of the application can be installed on the vehicle bottom longitudinal beam 200 through the self-mounting structure 6, the battery replacement frame is omitted, and the battery 1 is arranged in a plurality of forms, thereby the capacity can be large, the distance between the battery replacement stations 2000 is shortened, the number of the battery replacement stations 2000 is reduced, and the cost is reduced.

[0218] Fourth, a vehicle model can only be matched with a single battery pack, and different application scenarios can only be matched with a single battery pack, so the flexibility of battery replacement is low, and the compatibility is poor.

[0219] The battery 1 can be arranged in multiple and individually detachably mounted to the vehicle bottom longitudinal beam 200, the compatibility can be obviously improved, the flexibility of battery replacement can be obviously improved, the adaptability and throughput of the battery replacement station 2000 can be increased, the number of the battery replacement station 2000 can be reduced, the distance between the battery replacement stations 2000 can be reduced, and the investment cost can be reduced.

[0220] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0221] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
