[0002] This application claims priority to Chinese patent application No. 202420615763.6, filed on March 28, 2024, entitled “Battery and Vehicle,” the entire contents of which are incorporated herein by reference. Technical Field
[0003] The present application relates to the field of battery technology, and in particular to a battery and a vehicle. Background Art
[0004] For pure electric vehicles, the relatively slow charging speed is a major issue that causes anxiety about energy replenishment and even range anxiety, affecting the driving experience.
[0005] Battery swap stations, as a fast way to replenish energy, can effectively solve the problem of slow energy replenishment. However, the battery replacement process is cumbersome due to the battery connector replacement process, which affects the efficiency of battery replacement.
[0006] Summary of the Invention
[0007] The present application provides a battery and a vehicle to improve the battery replacement efficiency.
[0008] In the first aspect, the present application provides a battery, comprising a case, a battery cell, a thermal management component, a first connector, a second connector and a bracket; the case has a accommodating space; the battery cell is accommodated in the accommodating space; the thermal management component is accommodated in the accommodating space, and the thermal management component is used to accommodate a fluid to manage the temperature of the battery cell; the first connector is electrically connected to the battery cell; the second connector is connected to the thermal management component; the bracket is connected to the case, and the first connector and the second connector are both arranged on the bracket, and at least a portion of the first connector and at least a portion of the second connector are located outside the case.
[0009] In the above technical solution, the first connector is connected to the battery cell in the box, and the first connector can be externally connected to the connector of the vehicle to realize the electrical connection between the vehicle and the battery. The second connector is connected to the thermal management component in the box, and the second connector can be externally connected to the connector of the vehicle to realize the fluid conversion between the vehicle and the thermal management component to maintain the effectiveness of the thermal management component in managing the temperature of the battery cell. The first connector and the second connector are arranged on the bracket, and at least part of the first connector and at least part of the second connector are located outside the box. When performing a battery replacement operation, the first connector and the second connector arranged on the bracket can move toward the connector of the vehicle together with the bracket, and the first connector and the second connector can be directly docked with the connector of the vehicle respectively, reducing human participation in the battery replacement process, and realizing the quick connection of the first connector and the second connector with the corresponding connector of the vehicle, thereby realizing quick replacement of the battery, thereby improving the battery replacement efficiency.
[0010] In some embodiments, the housing includes a first portion and a second portion, the first portion and the second portion together defining a storage space. The first portion and the second portion are arranged along a first direction, with the first portion supporting the second portion. A bracket is connected to the first portion, and a first connector and a second connector are both connected to a side of the bracket facing away from the first portion. By arranging the first and second portions along the first direction, with the first portion supporting the second portion, the first portion can withstand the weight of the second portion, thereby reducing the strength requirements of the material for the second portion and saving material. By arranging the bracket to the first portion and the first and second connectors to the sides of the bracket facing away from the first portion, when the first and second connectors mate with a vehicle connector, since at least portions of the first and second connectors are located outside the housing, at least portions of the first and second connectors can contact the vehicle connector first. The vehicle's reaction force on the first and second connectors can be transmitted to the first portion via the bracket, reducing the risk of damage to the second portion from direct contact with the vehicle and improving battery reliability.
[0011] In some embodiments, a through hole for extending the first and second connectors is provided on a side of the second portion facing away from the first portion along the first direction. The through hole communicates with the storage space, and a bracket seals the through hole. The provision of the through hole allows the first and second connectors to achieve electrical and fluid communication with the vehicle through the through hole. The provision of the bracket seals the through hole, thereby isolating the storage space from the external environment when the first and second connectors are extended, reducing the impact of the external environment on other components within the housing.
[0012] In some embodiments, the bracket includes a first connecting portion, a second connecting portion and a supporting portion. The first connecting portion is connected to the first part, and the first part is accommodated in the accommodating space. The second connecting portion is arranged opposite to the first connecting portion along a first direction, the first connector and the second connector are both connected to the second connecting portion, and the second connecting portion closes the through hole. The supporting portion connects the first connecting portion and the second connecting portion. By connecting the first connecting portion to the first part and the second connecting portion blocking the through hole, the bracket can be set in the box, reducing the space occupied by the bracket and the box. By arranging that the first connector and the second connector are both connected to the second connecting portion and the second connecting portion blocks the through hole on the second part, the force applied to the first connector and the second connector during installation can be transmitted to the first part through the bracket, thereby reducing the risk of the second part being damaged by the force.
[0013] In some embodiments, along the first direction, a first surface is formed on the side of the second connection portion facing away from the first connection portion, the first surface is used to abut against the second part, the first surface is provided with a protrusion, the protrusion at least partially extends into the through hole, and the first connector and the second connector are provided on the protrusion. By abutting the first surface with the second part, the connection stability of the second connection portion and the second part can be improved. By providing a protrusion on the first surface and at least partially extending the protrusion into the through hole, the second part can be positioned by the protrusion and the through hole, which facilitates the installation of the first part and the second part and improves the installation efficiency of the box. By arranging the first connector and the second connector on the protrusion, the first connector and the second connector can be more protruding from the side facing away from the first part, which facilitates the cooperation of the first connector and the second connector with the connector of the vehicle respectively.
[0014] In some embodiments, along the first direction, the bracket has a second surface farthest from the first portion, and the first connector and the second connector both protrude from the second surface. The second surface is rectangular, the diagonal of the rectangle passes through the first connector and the second connector, the midpoint of the diagonal is located between the first connector and the second connector, the minimum distance between the first connector and the end of the diagonal near the first connector is a first distance, the minimum distance between the second connector and the end of the diagonal near the second connector is a second distance, the minimum distance between the first connector and the second connector is a third distance, and the sum of the first distance and the second distance is less than the third distance. By setting the second surface to be rectangular and the midpoint of the diagonal of the rectangle to be between the first connector and the second connector, the first connector and the second connector are at a relatively large distance, which facilitates more stable mating of the first connector and the second connector with the connector of the vehicle.
[0015] In some embodiments, the bracket includes a first connection part, a second connection part and a support part. The first connection part is connected to one side of the box along the first direction. The second connection part is arranged opposite to the first connection part along the first direction, and the first connector and the second connector are both connected to the second connection part. The support part connects the first connection part and the second connection part. By setting the first connection part, the first connection part can be connected to the box, and by setting the support part and the second connection part, the support part can support the second connection part. By setting the first connector and the second connector on the second connection part, the second connection part is located on the side of the bracket away from the box, so that the first connector and the second connector are fixed to the outside of the box and detached from the box, reducing the risk of the first connector and the second connector being damaged by contact with the box. At least part of the first connector and the second connector are at least partly located outside the box. When the box moves toward the vehicle, the bracket can carry the first connector and the second connector to move, facilitating quick replacement of the first connector and the second connector.
[0016] In some embodiments, the bracket further includes a reinforcement member connected to the first connecting portion, the reinforcement member being used to increase the strength of the first connecting portion. By providing the reinforcement member, the strength of the first connecting portion can be increased and the risk of the first connecting portion being damaged can be reduced.
[0017] In some embodiments, a reinforcement member is disposed on a side of the first connecting portion facing away from the second connecting portion, connecting the first connecting portion to the housing. By disposing the reinforcement member between the first connecting portion and the housing, the reinforcement member can strengthen the connection between the first connecting portion and the housing, reducing the risk of the first connecting portion detaching from the housing.
[0018] In some embodiments, a cavity is provided inside the reinforcement member. By providing the cavity inside the reinforcement member, the cavity can reduce consumable materials of the reinforcement member, reduce the weight of the reinforcement member, and save costs.
[0019] In some embodiments, the cavity penetrates the reinforcement along a second direction, the second direction being perpendicular to the first direction. By penetrating the reinforcement along the second direction, the mass of the reinforcement is further reduced, the processing difficulty of the cavity is reduced, and the transfer of the reinforcement through the cavity is facilitated.
[0020] In some embodiments, the first connection portion includes a connection area and an installation area. The reinforcement member and the support portion are both connected to the connection area. The installation area is connected to the connection area and is located on at least one side of the connection area along a third direction. The installation area is used to install other components, and the third direction is perpendicular to the first direction. By connecting both the reinforcement member and the support portion to the connection area, the connection between the reinforcement member and the support portion is achieved through the connection area. By providing the installation area, the installation area is also connected to the box body, and other components can be installed in the installation area, thereby improving the utilization rate of the first connection portion, increasing the contact area between the first connection portion and the box body, and improving the connection stability between the first connection portion and the box body.
[0021] In some embodiments, the second connector communicates with the thermal management component via a first conduit, and the mounting area is provided with a hole for the first conduit to pass through. By providing the first conduit and the hole in the mounting area, the hole can restrict the position of the first conduit, thereby improving the stability of the first conduit and reducing the risk of damage to the first conduit.
[0022] In some embodiments, the first connecting portion includes two mounting areas, one located on either side of the reinforcement along the third direction. Providing two mounting areas increases the area available for mounting other components, increases the contact area between the first connecting portion and the housing, and enhances the practicality of the first connecting portion.
[0023] In some embodiments, there are multiple supporting parts, and the multiple supporting parts are arranged between the first connecting part and the second connecting part at intervals. By providing multiple supporting parts, the connection between the first connecting part and the second connecting part is made more stable.
[0024] In some embodiments, the projection of the first connecting portion along the first direction completely covers the second connecting portion. By ensuring that the projection of the first connecting portion along the first direction completely covers the second connecting portion, the contact area between the first connecting portion and the box can be greater than or equal to the contact area between the second connecting portion and the vehicle, thereby improving the stability of the first connecting portion.
[0025] In some embodiments, the projected area of the first connecting portion is larger than the projected area of the second connecting portion along the first direction. By setting the projected area of the first connecting portion larger than the projected area of the second connecting portion along the first direction, a portion of the first connecting portion is exposed from the second connecting portion along a direction perpendicular to the first direction, facilitating the installation of other components and improving the utilization rate of the first connecting portion.
[0026] In some embodiments, the bracket is detachably connected to the housing. By detachably connecting the bracket and the housing, the bracket and the housing are easily repaired and replaced, thereby increasing the service life of the bracket or the housing.
[0027] In a second aspect, an embodiment of the present application provides a vehicle comprising a vehicle body and a battery provided by any one embodiment of the first aspect, wherein the first connector and the second connector are both connected to the vehicle body to electrically connect the battery to the vehicle body and to fluidically connect the battery to the vehicle body.

[0040] The following detailed description of the embodiments of the present application is provided in conjunction with the accompanying drawings and examples. The following detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of the present application, but are not intended to limit the scope of the present application, that is, the present application is not limited to the described embodiments.
[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.
[0042] In the description of the embodiments of the present application, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features.
[0043] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0044] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces), unless otherwise clearly and specifically defined.
[0045] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.
[0046] The term "multiple" in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).
[0047] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.
[0048] Battery cells include but are not limited to lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc.
[0049] As an example, the battery cell may be a cylindrical battery cell, a prismatic battery cell, a soft-pack battery cell or a battery cell of other shapes. Prismatic battery cells include square-shell battery cells, blade-shaped battery cells, and polygonal prismatic batteries. Polygonal prismatic batteries are, for example, hexagonal prismatic batteries.
[0050] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity.
[0051] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.
[0052] In some embodiments, the battery may be an energy storage device, including an energy storage container, an energy storage cabinet, and the like.
[0053] Batteries typically include a housing, battery cells, and a thermal management component. The battery cells are housed in the housing and are used to provide electrical energy. The thermal management component can also be located within the housing to manage the temperature of the battery cells.
[0054] When the battery is in use, the housing needs to be placed in the vehicle, and the battery cells and thermal management components must be connected to the vehicle to enable the battery cells to power the vehicle and to update the fluid in the thermal management components through the vehicle to maintain the normal operation of the thermal management components. The electrical connection between the battery cells and the vehicle, as well as the connection between the thermal management components and the vehicle, usually requires manual operation. The electrical connector connecting the battery cells and the water connector connecting the thermal management components need to be manually connected to the vehicle to replace the battery. For many vehicles, the efficiency of battery replacement is related to the efficiency of vehicle use and affects the user experience.
[0055] Taking a heavy truck as an example, after the box is fixed to the heavy truck, it is necessary to connect the first connector connected to the battery cell to the heavy truck, and the second connector connected to the thermal management component to the heavy truck. Since the battery cell and the first connector are usually connected by wires, and the thermal management component and the second connector are usually connected by pipes, the wires and pipes are not fixed, and the first connector and the second connector are more mobile, so the two connectors need to be manually connected to the heavy truck, which reduces the battery replacement efficiency and makes it difficult to achieve quick battery replacement.
[0056] To improve the problem of low battery swapping efficiency, an embodiment of the present application provides a battery having a bracket for connecting to a housing. A first connector electrically connected to the battery cells and a second connector connected to a thermal management component are disposed on the bracket, with at least a portion of the first connector and at least a portion of the second connector exposed to the exterior of the housing. When the housing moves toward a connector connected to a vehicle, the first and second connectors can follow the movement of the bracket and directly dock with the vehicle's connector, enabling quick battery swapping and thereby improving battery swapping efficiency.
[0057] For the convenience of description, the following embodiments are described using a vehicle as an example.
[0058] Please refer to Figure 1, which is a schematic diagram of the structure of a vehicle 100 provided in some embodiments of the present application. A battery 10 is disposed within the vehicle 100. Battery 10 can be located at the bottom, front, or rear of the vehicle 100. Battery 10 can be used to power the vehicle 100, for example, as the operating power source of the vehicle 100.
[0059] The vehicle 100 may further include a controller 20 and a motor 30 . The controller 20 is used to control the battery 10 to supply power to the motor 30 , for example, to meet the power requirements of starting, navigating, and driving the vehicle 100 .
[0060] In some embodiments of the present application, the battery 10 can serve not only as an operating power source for the vehicle 100 , but also as a driving power source for the vehicle 100 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 100 .
[0061] Please refer to Figure 2, which is an exploded view of a battery 10 provided in some embodiments of the present application. Battery 10 includes a housing 2, battery cells 3, and a thermal management component 4. Battery cells 3 are housed within housing 2. Thermal management component 4 is housed within housing 2 and is used to contain a fluid to manage the temperature of battery cells 3.
[0062] The housing 2 is a component that houses the battery cells 3 and provides a storage space 2a for the battery cells 3. The housing 2 can have various structures. In some embodiments, the housing 2 can include a first portion 21 and a second portion 22, which overlap to define a storage space 2a for the battery cells 3. The first portion 21 and the second portion 22 can have various shapes, such as a rectangular parallelepiped or a cylinder. The first portion 21 can be a hollow structure with one side open, and the second portion 22 can also be a hollow structure with one side open. The open side of the second portion 22 overlaps the open side of the first portion 21, forming the housing 2 with the storage space 2a. Alternatively, the first portion 21 can be a hollow structure with one side open, and the second portion 22 can be a plate-like structure. The second portion 22 overlaps the open side of the first portion 21, forming the housing 2 with the storage space 2a. The first portion 21 and the second portion 22 can be sealed using a sealing element, such as a sealing ring or sealant. The material of the box body 2 can be copper, iron, aluminum, stainless steel, aluminum alloy, etc.
[0063] According to different power requirements, the number of battery cells 3 can be set to any value. Multiple battery cells 3 can be connected in series, parallel or mixed to achieve a larger capacity or power. Since the number of battery cells 3 included in each battery 10 may be large, in order to facilitate installation, the battery cells 3 can be grouped, and each group of battery cells 3 constitutes a battery module 3a. The number of battery cells 3 included in the battery module 3a is not limited and can be set according to demand. The battery 10 may include multiple battery modules 3a, and these battery modules 3a can be connected in series, parallel or mixed. As an example, as shown in Figure 2, a plurality of battery modules 3a are arranged in the box 2, and the battery module 3a includes a plurality of battery cells 3. The thermal management component 4 is arranged in the box 2 to manage the temperature of the battery cells 3.
[0064] Thermal management component 4 can be a component with both heating and cooling functions. When the temperature of battery cell group 3 is too high, thermal management component 4 is used to cool the battery cell group 3. When the temperature of battery cell group 3 is too low, thermal management component 4 is used to heat the battery cell group 3. Thermal management component 4 can be selected from existing technologies, and its existing structure is not described in detail here. By adjusting the temperature of battery cell group 3 by thermal management component 4, the battery cell group 3 can operate in a suitable environment, thereby improving the operating efficiency and reliability of battery 10.
[0065] In some embodiments, the battery 10 may further include a first connector 5 electrically connected to the battery cell 3. The first connector 5 may be electrically connected to the battery cell 3 via a wire, and the first connector 5 may be a contact connector or a pluggable connector.
[0066] In some embodiments, the battery 10 may further include a second connector 6, which is in communication with the thermal management component 4. The thermal management component 4 may be a liquid-cooled thermal management component 4. For example, the thermal management component 4 may be in communication with the second connector 6 via a pipe, and the thermal management component 4 may renew the fluid within the thermal management component 4 via the pipe.
[0067] In the embodiments of the present application, please refer to Figure 3, which is a schematic diagram of the structure of the battery 10 provided in some embodiments of the present application. The battery 10 includes a case 2, a battery cell 3, a thermal management component 4, a first connector 5, a second connector 6 and a bracket 1. The case 2 has a accommodating space 2a, the battery cell 3 is accommodated in the accommodating space 2a, and the thermal management component 4 is accommodated in the accommodating space 2a. The thermal management component 4 is used to accommodate a fluid to manage the temperature of the battery cell 3. The first connector 5 is electrically connected to the battery cell 3. The second connector 6 is in communication with the thermal management component 4. The bracket 1 is connected to the case 2, and the first connector 5 and the second connector 6 are both arranged on the bracket 1. At least a portion of the first connector 5 and at least a portion of the second connector 6 are located outside the case 2.
[0068] The number of first connectors 5 can be one or more. The first connector 5 is used to electrically connect to the battery cell 3. If there are multiple battery modules 3a in the housing 2, the multiple battery modules 3a can be connected in series and then electrically connected to the first connector 5, or in parallel and then electrically connected to the first connector 5, or multiple battery modules 3a can be connected in series and then electrically connected to the first connector 5. The first connector 5 can protrude from the bracket 1 and mate with a connector provided on the vehicle 100 to achieve connection, or the first connector 5 can be recessed in the bracket 1 and mate with a connector provided on the vehicle 100 to achieve connection.
[0069] The number of second connectors 6 can be one or more. If there is one second connector 6, the second connector 6 has a water inlet channel and a water outlet channel, both of which are connected to the thermal management component 4. The coolant can flow from the water inlet channel into the thermal management component 4, flow through the thermal management component 4, and then flow out from the water outlet channel. If there are multiple second connectors 6, for example, there are two second connectors 6, the two second connectors 6 are respectively a water inlet connector and a water outlet connector, the water inlet connector has a water inlet channel, and the water outlet connector has a water outlet channel. The coolant flows from the water inlet connector into the thermal management component 4, flows through the thermal management component 4, and then flows out from the water outlet connector.
[0070] The bracket 1 can be integrally connected to the housing 2, for example, the bracket 1 can be welded to the housing 2; the bracket 1 can also be detachably connected to the housing 2, for example, the bracket 1 is locked to the housing 2 via a locking accessory, wherein the locking accessory can be a bolt, rivet, etc. The bracket 1 can be located outside the housing 2 or inside the housing 2. The material of the bracket 1 can be copper, iron, aluminum, stainless steel, aluminum alloy, etc. The material of the bracket 1 can be the same as the material of the housing 2, or different from the material of the housing 2. The strength of the bracket 1 can be higher than the strength of the housing 2, or lower than the strength of the housing 2.
[0071] In the above embodiment, the first connector 5 is connected to the battery cell 3 in the housing 2. The first connector 5 can be connected to the connector of the vehicle 100 to achieve electrical connection between the vehicle 100 and the battery 10. The second connector 6 is connected to the thermal management component 4 in the housing 2. The second connector 6 can be connected to the connector of the vehicle 100 to achieve fluid conversion between the vehicle 100 and the thermal management component 4 to maintain the effectiveness of the thermal management component 4 in managing the temperature of the battery cell 3. The first connector 5 and the second connector 6 are arranged on the bracket 1, and at least a portion of the first connector 5 and at least a portion of the second connector 6 are located outside the housing 2. When performing a battery replacement operation, the first connector 5 and the second connector 6 arranged on the bracket 1 can move with the bracket 1 toward the connector of the vehicle 100, so that the first connector 5 and the second connector 6 can be directly connected to the connector of the vehicle 100, respectively, reducing human intervention in the battery replacement process and achieving quick replacement of the first connector 5 and the second connector 6 with the connector of the vehicle 100, thereby improving the battery replacement efficiency of the battery 10.

The first portion 21 and the second portion 22 are arranged along a first direction X, with the first portion 21 supporting the second portion 22. The bracket 1 is connected to the first portion 21. Along the first direction X, the first connector 5 and the second connector 6 are connected to the side of the bracket 1 facing away from the first portion 21.
[0073] The first part 21 may be a plate-like structure, the second part 22 may be a hollow structure with one side open, and the second part 22 may cover the first part 21; or the first part 21 may be a hollow structure with one side open, the second part 22 may be a hollow structure with one side open, and the open side of the first part 21 may cover the open side of the second part 22.
[0074] As an example, as shown in Figure 3, along a first direction X, the first portion 21 supports the second portion 22. The second portion 22 includes a first plate 223, a first protrusion 221, and two second protrusions 222. The first plate 223 connects to the first portion 21. The first protrusion 221 and the two second protrusions 222 are both disposed on the first plate 223 and spaced apart along a third direction Z. The first protrusion 221 is located between the two second protrusions 222. The second protrusions 222 define a cavity for accommodating the battery module 3a. At least a portion of the bracket 1 is disposed within the first protrusion 221. The cavity is a portion of the accommodating space 2a. The first direction X is parallel to the direction of gravity, and the third direction Z is the longitudinal direction of the battery 10.
[0075] By arranging the first portion 21 and the second portion 22 along the first direction X, and with the first portion 21 supporting the second portion 22, the first portion 21 can bear the weight of the second portion 22, thereby reducing the strength requirements of the material of the second portion 22 and saving materials. By arranging the bracket 1 connected to the first portion 21 and the first connector 5 and the second connector connected to the side of the bracket 1 facing away from the first portion 21, when the first connector 5 and the second connector 6 are docked with the connector of the vehicle 100, since at least a portion of the first connector 5 and at least a portion of the second connector 6 are located outside the box 2, at least a portion of the first connector 5 and at least a portion of the second connector 6 can first contact the connector of the vehicle 100. The reaction force of the vehicle 100 on the first connector 5 and the second connector 6 can be transmitted to the first portion 21 through the bracket 1, reducing the risk of damage to the second portion 22 due to direct contact with the vehicle 100, and improving the reliability of the battery 10.
[0076] Furthermore, in battery 10, second portion 22 can primarily serve as a cover, thereby reducing the strength of second portion 22 and increasing the strength of first portion 21, which serves as a support. Connecting bracket 1 to first portion 21 allows bracket 1 to directly transmit forces applied to first portion 21, reducing the risk of damage to second portion 22 due to insufficient strength. Since forces acting on first and second connectors 5 and 6 when positioned on first protrusion 221 are directly transmitted to first protrusion 221, potentially damaging it, positioning first and second connectors 5 and 6 on bracket 1 reduces the risk of damage to first protrusion 221.
[0077] In some embodiments, please continue to refer to Figures 3 and 4. Along the first direction X, a through hole 2211 for leading out the first connector 5 and the second connector 6 is provided on the side of the second part 22 facing away from the first part 21. The through hole 2211 is connected to the accommodating space 2a, and the bracket 1 closes the through hole 2211.
[0078] The bracket 1 may be located in the accommodating space 2a, the bracket 1 closes the through hole 2211, and the first connector 5 and the second connector 6 on the bracket 1 are exposed in the through hole 2211; the bracket 1 may be located outside the box body 2, the bracket 1 blocks the through hole 2211; or a part of the bracket 1 may be located in the accommodating space 2a, and the other part may be located outside the box body 2, and the first connector 5 and the second connector 6 are arranged on the part of the bracket 1 located outside the box body 2.
[0079] By providing through-hole 2211, first connector 5 and second connector 6 can achieve electrical connection and fluid communication with vehicle 100 through through-hole 2211. By providing bracket 1 to seal through-hole 2211, accommodating space 2a can be isolated from the external environment when first connector 5 and second connector 6 are led out, reducing the impact of the external environment on other components within housing 2. These other components may include a control unit, connectors, wire clamps, etc. within battery 10.
[0080] In some embodiments, please refer to Figures 3 to 5. Figure 5 is a schematic structural diagram of the bracket 1 and the first part 21 provided in some embodiments of the present application. The bracket 1 includes a first connecting portion 11, a second connecting portion 12, and a supporting portion 13. The first connecting portion 11 is connected to the first part 21, and the first part 21 is accommodated in the accommodating space 2a. The second connecting portion 12 is arranged opposite to the first connecting portion 11 along the first direction X, and the first connector 5 and the second connector 6 are both connected to the second connecting portion 12, and the second connecting portion 12 closes the through hole 2211. The supporting portion 13 connects the first connecting portion 11 and the second connecting portion 12.
[0081] The first connecting portion 11 is the portion of the bracket 1 that connects to the first portion 21. The first connecting portion 11 can be plate-shaped. The first connecting portion 11 and the first portion 21 can be fixedly connected, for example, by welding the first connecting portion 11 to the housing 2. Alternatively, the first connecting portion 11 and the first portion 21 can be detachably connected, for example, by bolting the first connecting portion 11 to the first portion 21. The first connecting portion 11 and the first portion 21 can be directly connected or indirectly connected.
[0082] The second connecting portion 12 may be plate-shaped and may abut against the surface of the first protrusion 221 facing the first portion 21 to close the through-hole 2211. Alternatively, a portion of the second connecting portion 12 may be located within the through-hole 2211, while another portion abuts against the wall of the through-hole 2211 to close the through-hole 2211. Alternatively, the entire second connecting portion 12 may be located within the through-hole 2211 to close the through-hole 2211. The second connecting portion 12 is disposed opposite the first connecting portion 11, and may be disposed parallel to the first connecting portion 11.
[0083] The support portion 13 is the portion of the bracket 1 connected between the first connection portion 11 and the second connection portion 12. The support portion 13 can be in the shape of a plate, a column, etc. The number of the support portions 13 can be one or more.
[0084] As an example, the first direction X can be the direction of gravity. The first connecting portion 11 is located below the second connecting portion 12. The first connecting portion 11 is mounted on the top of the first part 21. The second connecting portion 12 closes the through-hole 2211 of the second part 22. The first connector 5 and the second connector 6 are both disposed on the second connecting portion 12 and protrude from the exterior of the case 2. When docking the battery 10 with the vehicle 100, the case 2 can be moved upward from the bottom so that the first connector 5 and the second connector 6 dock with the corresponding connectors on the vehicle body. The first connector 5 and the second connector 6 respectively transmit the force applied by the vehicle 100 to the first part 21 through the bracket 1, reducing the risk of damage to the second part 22 from contact with the vehicle body and improving the structural stability of the battery 10.
[0085] By connecting the first connecting portion 11 to the first part 21 and the second connecting portion 12 to block the through hole 2211, the bracket 1 can be placed inside the box 2, reducing the space occupied by the bracket 1 and the box 2. By arranging that the first connector 5 and the second connector 6 are both connected to the second connecting portion 12, and the second connecting portion 12 blocks the through hole 2211 in the second part 22, the forces applied to the first connector 5 and the second connector 6 during installation can be transmitted to the first part 21 through the bracket 1, thereby reducing the risk of damage to the second part 22 due to the force.
[0086] In some embodiments, along the first direction X, a first surface 121 is formed on the side of the second connecting portion 12 facing away from the first connecting portion 11, and the first surface 121 is used to abut against the second portion 22. The first surface 121 is provided with a protrusion 122, and the protrusion 122 at least partially extends into the through hole 2211, and the first connector 5 and the second connector 6 are provided on the protrusion 122.
[0087] The entire first surface 121 may abut against the second portion 22 ; or a portion of the first surface 121 may abut against the second portion 22 , and the other portion may be located in the through hole 2211 .
[0088] The entire protrusion 122 may be located in the through hole 2211, and the first connector 5 and the second connector 6 may be arranged in the protrusion 122 and pass through the through hole 2211; or only a part of the protrusion 122 may be located in the through hole 2211, and the first connector 5 and the second connector 6 may be arranged in the part of the protrusion 122 located in the through hole 2211 and pass through the through hole 2211.
[0089] As an example, please continue to refer to Figures 3 and 4. The entire protrusion 122 is located in the through hole 2211, the first surface 121 is provided with a first mounting hole 1211, and the first protrusion 221 is provided with a second mounting hole 2212. The bolt passes through the first mounting hole 1211 and the second mounting hole 2212 to lock the second connecting part 12 and the first protrusion 221.
[0090] By abutting the first surface 121 against the second portion 22, the connection stability between the second connecting portion 12 and the second portion 22 can be improved. By providing a protrusion 122 on the first surface 121, with at least a portion of the protrusion 122 extending into the through-hole 2211, the second portion 22 can be positioned via the protrusion 122 and the through-hole 2211, facilitating the installation of the first and second portions 21, 22 and improving the installation efficiency of the box 2. By providing the first and second connectors 5 and 6 on the protrusion 122, the first and second connectors 5 and 6 can protrude further from the side facing away from the first portion 21, facilitating the mating of the first and second connectors 5 and 6 with the connectors of the vehicle 100.
[0091] In some embodiments, along the first direction X, the bracket 1 has a second surface 1221 farthest from the first portion 21, and the first connector 5 and the second connector 6 both protrude from the second surface 1221. The second surface 1221 is rectangular, with the diagonal of the rectangle passing through the first connector 5 and the second connector 6, and the midpoint of the diagonal located between the first connector 5 and the second connector 6.
[0092] In the embodiment where the first surface 121 of the second connecting portion 12 is provided with a protrusion 122, the end surface of the protrusion 122 facing away from the first surface 121 may be the second surface 1221. In the embodiment where the first surface 121 of the second connector 6 is not provided with a protrusion 122, the second surface 1221 may be the first surface 121.
[0093] The midpoint of the diagonal line is located between the first connector 5 and the second connector 6 , that is, the first connector 5 and the second connector 6 are located on both sides of the midpoint of the diagonal line along the extension direction of the diagonal line.
[0094] As an example, along the diagonal extension direction, the minimum distance between the first connector 5 and one end of the diagonal (the end of the diagonal closest to the first connector 5) is a first distance, the minimum distance between the second connector 6 and the other end of the diagonal (the end of the diagonal closest to the second connector 6) is a second distance, and the minimum distance between the first connector 5 and the second connector 6 is a third distance, where the sum of the first and second distances is less than the third distance. This structure allows the first connector 5 and the second connector 6 to be located near the diagonal corners of the rectangle, further increasing the distance between the first connector 5 and the second connector 6.
[0095] By setting the second surface 1221 to be rectangular and the midpoint of the diagonal of the rectangle to be located between the first connector 5 and the second connector 6, the first connector 5 and the second connector 6 are at a relatively far distance, thereby reducing the risk of interference between the first connector 5 and the second connector 6, and facilitating a more stable fit between the first connector 5 and the second connector 6 and the connector of the vehicle 100.
[0096] In some embodiments, please refer to Figure 6, which is a schematic diagram of the structure of a bracket 1 provided in some embodiments of the present application. The bracket 1 includes a first connecting portion 11, a second connecting portion 12, and a support portion 13. The first connecting portion 11 is connected to one side of the housing 2 along the first direction X. The second connecting portion 12 is arranged opposite the first connecting portion 11 along the first direction X, and the first connector 5 and the second connector 6 are both connected to the second connecting portion 12. The support portion 13 connects the first connecting portion 11 and the second connecting portion 12.
[0097] The first connecting portion 11 can be plate-shaped. The first connecting portion 11 can be fixedly connected to the housing 2, for example, by welding the first connecting portion 11 to the housing 2. Alternatively, the first connecting portion 11 can be detachably connected to the housing 2, for example, by bolting the first connecting portion 11 to the first portion 21. The first connecting portion 11 can be directly connected to the housing 2, or indirectly connected to the housing 2.
[0098] The first direction X can be the direction of gravity. When installing the battery 10, the first connecting part 11 can be located below the second connecting part 12, and the box body 2 can be moved from bottom to top so that the first connecting part 11 and the second connecting part 12 are docked with the connectors corresponding to the vehicle body. The first connecting part 11 and the second connecting part 12 respectively transmit the force applied by the vehicle 100 to the box body 2 through the bracket 1, thereby reducing the risk of damage to the box body 2.
[0099] The first connection portion 11 and the second connection portion 12 are arranged opposite to each other along the first direction X, which means that there is a gap between the first connection portion 11 and the second connection portion 12 in the first direction X, and the projections of the first connection portion 11 and the second connection portion 12 in the first direction X at least partially overlap.
[0100] By setting the first connecting part 11, the first connecting part 11 can be connected to the box body 2, and by setting the supporting part 13 and the second connecting part 12, the supporting part 13 can support the second connecting part 12. By setting the first connector 5 and the second connector 6 on the second connecting part 12, at least part of the first connector 5 and at least part of the second connector 6 are fixed to the outside of the box body 2, so that when the battery 10 is docked with the vehicle 100, the force exerted on the first connector 5 and the second connector 6 can be transmitted to the box body 2 through the second connecting part 12, the supporting part 13 and the first connecting part 11, thereby reducing the risk of the box body 2 being damaged by contact with the vehicle 100, and at least part of the first connector 5 and at least part of the second connector 6 are located outside the box body 2. When the box body 2 moves toward the vehicle 100, the bracket 1 can carry the first connector 5 and the second connector 6 to move, thereby facilitating quick replacement of the first connector 5 and the second connector 6.
[0101] In some embodiments, please refer to FIG7 , which is a schematic structural diagram of a bracket 1 provided in some embodiments of the present application. The bracket 1 further includes a reinforcement 14 connected to the first connecting portion 11 to enhance the strength of the first connecting portion 11 .
[0102] The number of reinforcement members 14 may be one or more. The reinforcement member 14 may be a solid plate structure or a hollow structure. The reinforcement member 14 may be fixedly connected to the first connecting portion 11, for example, the reinforcement member 14 is welded to the first connecting portion 11; the reinforcement member 14 may also be detachably connected to the first connecting portion 11, for example, the reinforcement member 14 is bolted to the first connecting portion 11 by bolts. Along the first direction X, the reinforcement member 14 may be located between the first connecting portion 11 and the second connecting portion 12, or between the first connecting portion 11 and the first part 21. When there are multiple reinforcement members 14, the reinforcement members 14 may be located on both sides of the first connecting portion 11 along the first direction X, or on the same side of the first connecting portion 11.
[0103] By providing the reinforcement member 14 , the strength of the first connection portion 11 can be increased, and the risk of the first connection portion 11 being damaged can be reduced.
[0104] In some embodiments, the reinforcement member 14 is disposed on a side of the first connection portion 11 away from the second connection portion 12 , and the reinforcement member 14 connects the first connection portion 11 and the box body 2 .
[0105] As an example, as shown in FIG. 7 , the first direction X is parallel to the gravity direction of the bracket 1 , and the reinforcement 14 is connected to the first connection portion 11 and is located below the first connection portion 11 .
[0106] By arranging the reinforcement member 14 between the first connection portion 11 and the box body 2 , the reinforcement member 14 can strengthen the connection between the first connection portion 11 and the box body 2 , thereby reducing the risk of the first connection portion 11 being separated from the box body 2 .
[0107] In some embodiments, a cavity 141 is provided inside the reinforcement member 14 .
[0108] The number of cavities 141 can be one or more. For example, the number of cavities 141 is multiple and the cavities 141 are spaced apart. The cavities 141 can penetrate the outer surface of the reinforcement 14 or be completely sealed within the reinforcement 14.
[0109] By providing a cavity 141 within the reinforcement member 14, the cavity 141 can reduce the consumable materials of the reinforcement member 14, reduce the weight of the reinforcement member 14, and save costs. When the reinforcement member 14 is disposed between the first connecting portion 11 and the first portion 21, the bracket 1 can transmit force to the first portion 21 through the reinforcement member 14. The hollow structure of the reinforcement member 14 helps to increase the cushioning effect of the bracket 1 on the first portion 21, reducing the risk of damage to the first portion 21.
[0110] In some embodiments, the cavity 141 penetrates the reinforcement member 14 along a second direction Y, and the second direction Y is perpendicular to the first direction X.
[0111] As an example, as shown in FIG7 , the first direction X is the gravity direction of the bracket 1 , the second direction Y is the width direction of the bracket 1 , and the third direction Z is the length direction of the bracket 1 . The cavity 141 passes through the reinforcement 14 along the width direction of the bracket 1 .
[0112] By penetrating the reinforcement 14 along the second direction Y, the mass of the reinforcement 14 is further reduced, the difficulty of processing the cavity 141 is reduced, and the transfer of the reinforcement 14 through the cavity 141 is facilitated.
[0113] In some embodiments, referring to FIG. 7 , the first connecting portion 11 includes a connecting region 111 and a mounting region 112. The reinforcement member 14 and the support portion 13 are both connected to the connecting region 111. The mounting region 112 is connected to the connecting region 111 and is located on at least one side of the connecting region 111 along a third direction Z perpendicular to the first direction X. The mounting region 112 is used to mount other components.
[0114] The connection area 111 is used to connect the reinforcement 14, the support portion 13, and the mounting area 112. The connection area 111 can be a mounting block or a bent sheet metal part. The reinforcement 14 can be located on the side of the connection area 111 facing away from the second connection portion 12, or on the side of the connection area 111 facing the second connection portion 12. The connection area 111 can be directly connected to the housing 2, or indirectly connected to the housing 2 through the reinforcement 14.
[0115] The number of mounting areas 112 can be one or more. The mounting area 112 and the connection area 111 can be separate or integrally formed. Along the first direction X, the projection of the mounting area 112 can be entirely within the second connection portion 12 or at least partially outside the second connection portion 12.
[0116] By connecting the reinforcement 14 and the support portion 13 to the connection area 111, the connection between the reinforcement 14 and the support portion 13 is achieved through the connection area 111. By setting the installation area 112, the installation area 112 is also connected to the box body 2, and other components can be installed in the installation area 112, thereby improving the utilization rate of the first connection portion 11, increasing the contact area between the first connection portion 11 and the box body 2, and improving the connection stability between the first connection portion 11 and the box body 2.
[0117] In some embodiments, there are multiple support portions 13 , and the multiple support portions 13 are spaced apart and arranged between the first connecting portion 11 and the second connecting portion 12 .
[0118] As an example, referring to FIG. 7 , there are four supporting portions 13 , and the four supporting portions 13 are respectively connected to the connecting area 111 and the second connecting portion 12 .
[0119] By providing multiple support portions 13, the multiple support portions 13 can transmit the force applied by the vehicle 100 to the first connector 5 and the second connector 6 to the second connection portion 12, and then transmit it to the first connection portion 11 through the support portion 13, thereby dispersing the pressure that a single support portion 13 needs to bear, reducing the risk of damage to the bracket by 1 times, and making the connection between the first connection portion 11 and the second connection portion 12 more stable.
[0120] In some embodiments, please refer to Figure 8, which is a schematic diagram of the structure of the bracket 1 provided in some embodiments of the present application. The second connector 6 is connected to the thermal management component 4 through the first pipe 7, and the installation area 112 is provided with a hole 1121 for the first pipe 7 to pass through.
[0121] As an example, as shown in FIG8 , the second connector 6 is connected to a first pipe 7 having a water inlet channel and a water outlet channel, both of which are connected to the thermal management component 4 in the housing 2 through the first pipe 7. A mounting area 112 is provided on one side of the connection area 111 along the length of the bracket 1. Both the connection area 111 and the mounting area 112 are provided with a third mounting hole 113 for passing a bolt through the third mounting hole 113 to fasten the first connecting portion 11 to the top of the first portion 21. The first pipe 7 is provided through the hole 1121 to achieve communication with the thermal management component 4 in the housing 2.
[0122] By providing the first pipe 7 and providing the hole 1121 in the installation area 112 , the hole 1121 can limit the position of the first pipe 7 , thereby improving the stability of the first pipe 7 and reducing the risk of the first pipe 7 being damaged.
[0123] In some embodiments, please refer to FIG9 , which is a schematic structural diagram of a bracket 1 provided in some other embodiments of the present application. The first connecting portion 11 includes two mounting areas 112 , and along the third direction Z, the two connecting areas 111 are respectively located on both sides of the reinforcement 14 .
[0124] As an example, as shown in Figure 9, there are two second connectors 6, namely a water inlet connector and a drainage connector. The water inlet connector and the drainage connector are respectively connected to a first pipe 7. There are two installation areas 112. The two installation areas 112 are respectively arranged on both sides of the connection area 111 along the third direction Z. Holes 1121 are respectively provided on the two installation areas 112. The two first pipes 7 are respectively passed through the two holes 1121 to achieve communication with the thermal management component 4 in the box body 2.
[0125] By providing two installation areas 112 , the area for installing other components is increased, the contact area between the first connection portion 11 and the box body 2 is increased, and the practicality of the first connection portion 11 is improved.
[0126] In some embodiments, please continue to refer to FIG9 . Along the first direction X, the projection of the first connection portion 11 completely covers the second connection portion 12 .
[0127] The projection of the first connection portion 11 along the first direction X may completely overlap with the projection of the second connection portion 12 along the first direction X, or only a portion of the projection of the first connection portion 11 along the first direction X may completely overlap with the projection of the second connection portion 12 along the first direction X.
[0128] By arranging the projection of the first connection portion 11 along the first direction X to completely cover the second connection portion 12 , the contact area between the first connection portion 11 and the box body 2 can be greater than or equal to the contact area between the second connection portion 12 and the vehicle 100 , thereby improving the stability of the bracket 1 .
[0129] In some embodiments, along the first direction X, a projected area of the first connection portion 11 is larger than a projected area of the second connection portion 12 .
[0130] As an example, as shown in FIG9 , along the first direction X, the projected area of the first connection portion 11 is larger than the projected area of the second connection portion 12. Along the first direction X, at least a portion of the projections of the two mounting portions are exposed beyond the second connection portion 12, allowing the second connection portion 12 to give way to other components when installing them, thereby reducing the risk of damaging other components if the second connection portion 12 is damaged.
[0131] By setting the projection area of the first connection portion 11 larger than the projection area of the second connection portion 12 along the first direction X, a portion of the first connection portion 11 is exposed from the second connection portion 12 along the direction perpendicular to the first direction X, which facilitates the installation of other components and improves the utilization rate of the first connection portion 11.
[0132] In some embodiments, the bracket 1 and the box 2 are detachably connected.
[0133] The bracket 1 and the box body 2 can be detachable through various connection methods. For example, the bracket 1 and the box body 2 are connected by locking accessories, which can be screws, bolts, etc. For another example, the bracket 1 and the box body 2 are snap-fitted.
[0134] The bracket 1 can be detachably connected to the first portion 21 of the box body 2 , and can also be detachably connected to the second portion 22 of the box body 2 .
[0135] As an example, referring to Figures 3 and 9 , the bracket 1 is detachably connected to the first portion 21 of the housing 2. Specifically, the first connecting portion 11 of the bracket 1 is located at the top of the first portion 21 of the housing 2. The first connecting portion 11 is provided with a third mounting hole 113, which is used to detachably connect the first connecting portion 11 to the first portion 21 via bolts. The second connecting portion 12 of the bracket 1 is connected to the second portion 22 of the housing 2, and at least a portion of the second connecting portion 12 is exposed at the through-hole 2211 of the second portion 22. The second connecting portion 12 is circumferentially provided with a first mounting hole 1211, and the first protrusion 221 of the second portion 22 is provided with a second mounting hole 2212. The second mounting holes 2212 are circumferentially provided around the through-hole 2211. The first mounting holes 1211 and the second mounting holes 2212 are used to detachably connect the second connecting portion 12 to the second portion 22 via bolts.
[0136] The detachable connection between the bracket 1 and the box 2 facilitates the maintenance and replacement of the bracket 1 and the box 2, thereby increasing the service life of the bracket 1 or the box 2.
[0137] An embodiment of the present application provides a vehicle 100, comprising a vehicle body and a battery 10 provided in any one of the above embodiments, wherein the first connector 5 and the second connector 6 are both connected to the vehicle body to electrically connect the battery 10 to the vehicle body and to fluidically connect the battery to the vehicle body.
[0138] In some embodiments, please refer to FIG10 , which is a schematic diagram of the structure of the battery 10 and the crossbeam 40 provided in some embodiments of the present application. The vehicle body also includes a crossbeam 40. As an example, as shown in FIG10 , there are two crossbeams 40 , both extending along the second direction Y. The two crossbeams 40 are respectively disposed through the first protrusion 221 and the two gaps between the two protrusions to secure the battery 10.
[0139] Referring to Figures 3-7 , an embodiment of the present application provides a battery 10 comprising a housing 2, battery cells 3, a thermal management component 4, a first connector 5, a second connector 6, and a bracket 1. The battery cells 3 and thermal management component 4 are housed within the housing 2. The housing 2 comprises a second portion 22 and a first portion 21 supporting the second portion 22. The bracket 1 comprises a first connecting portion 11, a second connecting portion 12, and a supporting portion 13. The supporting portion 13 connects the first and second connecting portions 11 and 12 and supports the second connecting portion 12. The first connecting portion 11 is disposed on top of the first portion 21. The second portion 22 is provided with a first protrusion 221, the top of which is provided with a through-hole 2211. The second connecting portion 12 is connected to the first protrusion 221. The first connector 5 and the second connector 6 are both disposed on the second connecting portion 12. The first connector 5 and the second connector 6 are inserted through the through-hole 2211, with portions of the first connector 5 and the second connector 6 located outside the housing 2. When the battery 10 is connected to the vehicle body, the first connector 5 and the second connector 6 can follow the movement of the bracket 1 to first dock with the corresponding connectors on the vehicle body. The vehicle body reacts force to the first connector 5 and the second connector 6. The first connector 5 and the second connector 6 will transmit the force received from the vehicle body to the bracket 1, and then be transmitted to the first part 21 by the bracket 1.
[0140] By setting the bracket 1 on the top of the first part 21 and setting at least part of the first connector 5 and at least part of the second connector 6 on the outside of the box body 2, when the box body 2 moves upward and close to the vehicle body, the first connector 5 and the second connector 6 can preferentially contact the vehicle body, so that the first connector 5 and the second connector 6 on the bracket 1 can directly dock with the vehicle body, thereby realizing the electrical connection between the vehicle body and the battery 10 and the communication of the fluid channel. When the bracket 1 is not damaged, the second part 22 does not contact the vehicle body, and the second part 22 is only subjected to the downward force generated by the deformation of the bracket 1, thereby reducing the risk of damage to the second part 22. When performing a battery replacement operation, the first connector 5 and the second connector 6 set on the bracket 1 can move together with the bracket 1 toward the connector of the vehicle body, so that the first connector 5 and the second connector 6 can be directly docked with the connector of the vehicle body, respectively, reducing human participation in the battery replacement process, and realizing the quick replacement of the first connector 5 and the second connector 6 with the connector of the vehicle body, thereby improving the battery replacement efficiency of the battery 10.
