In the present application, a battery 100 refers to a single physical module including at least one battery module 20 to provide a higher voltage and capacity. Among them, multiple battery modules 20 can be connected in series, in parallel or in mixed connection to form a battery 100. Mixed connection means that multiple battery modules 20 are both connected in series and in parallel. The battery module 20 may include one or more battery cells 221. When the battery module 20 includes multiple battery cells 221, the multiple battery cells 221 of the battery module 20 may be connected in series, in parallel or in mixed connection.

In the related art, with the development of battery technology, more and more vehicles use batteries as power sources. When batteries are used in vehicles as power sources, the batteries are usually installed on the beams of the vehicles. When the batteries need to be maintained or replaced, the batteries usually need to be removed from the beams. When the batteries are removed from the beams, the batteries are easily subjected to large impact forces under the action of their own gravity. When the battery is subjected to excessive impact forces or large impact forces for a long time, it is easy to cause internal damage to the battery, which seriously affects the service life of the battery.

Based on this, in order to reduce or avoid damage to the battery 100 due to impact force, the applicant, after in-depth research, proposed a battery 100, which is used to be installed on the beam 70 of the vehicle 1000. The battery 100 includes a load-bearing bracket 10 and at least one battery module 20. The load-bearing bracket 10 is used to bear the weight of the battery module 20 and is suitable for being detachably connected to the beam 70.

In the technical solution of the present application, a load-bearing bracket 10 is provided for bearing the weight of the battery module 20 and the load-bearing bracket 10 is detachably connected to the vehicle beam 70, so as to facilitate the replacement and maintenance of the battery 100. In addition, during the process of removing the battery 100 from the vehicle beam 70, the load-bearing bracket 10 can buffer and protect the battery 100, thereby reducing the damage to the battery 100 due to the large impact force under the action of its own gravity, and extending the service life of the battery 100. In addition, during the operation of the vehicle 1000, the impact force on the battery module 20 can be transmitted to the load-bearing bracket 10, so that the impact force on the battery module 20 can be dispersed and transmitted, thereby reducing or avoiding the damage to the battery module 20 due to the impact force, and extending the service life of the battery 100.

The battery 100 disclosed in the embodiment of the present application can be used in a vehicle 1000, and a power system of the vehicle 1000 including the battery 100 disclosed in the present application can be used to reduce or avoid damage to the battery 100 due to impact force.

The embodiment of the present application provides a vehicle 1000 using the battery 100 as a power source. The vehicle 1000 may be, but is not limited to, a truck, an engineering vehicle, a car, etc.

The battery 100 according to an embodiment of the present invention will be described below with reference to the drawings.

As shown in Figures 1-3, an embodiment of the present application provides a battery 100, which is used to be installed on the beam 70 of a vehicle 1000. The battery 100 includes a load-bearing bracket 10 and at least one battery module 20. The load-bearing bracket 10 is used to bear the weight of the battery module 20 and is suitable for being detachably connected to the beam 70.

The main function of the load-bearing bracket 10 is to bear the weight of all battery modules 20, and it can also play the role of installing and fixing the battery modules 20. The load-bearing bracket 10 can be a metal bracket, for example, the load-bearing bracket 10 can be a steel structure bracket, which can make the load-bearing bracket 10 have a higher structural strength, so that it can stably and reliably support multiple battery modules 20.

One of the battery modules 20 can be detachably mounted on the load-bearing bracket 10, some of the battery modules 20 can be detachably mounted on the load-bearing bracket 10, or each battery module 20 can be detachably mounted on the load-bearing bracket 10.

The “battery module 20 is detachably mounted on the load-bearing bracket 10” means that the battery module 20 can be removed from the load-bearing bracket 10, and the removed battery module 20 can also be reinstalled on the load-bearing bracket 10. The detachable connection method of the battery module 20 may include at least one of a snap connection method and a fastener connection method.

The accommodation space 101 defined in the load-bearing bracket 10 for accommodating the battery module 20 is connected to the external environment, and the accommodation space 101 defined in the load-bearing bracket 10 for accommodating the battery module 20 is an open space, so that at least part of the battery module 20 can be exposed to the external environment, which is convenient for disassembly and maintenance of the battery module 20. For example, the load-bearing bracket 10 can be a bracket structure with a hollow structure, and the load-bearing bracket 10 can also be a bracket structure with one side open, for example, the upper side of the load-bearing bracket 10 can be open, which can facilitate the battery module 20 to be loaded into the load-bearing bracket 10 from the top of the load-bearing bracket 10 or removed from the load-bearing bracket 10.

The load-bearing bracket 10 is suitable for being detachably connected to the vehicle beam 70, and the battery 100 is connected to the vehicle beam 70 through the load-bearing bracket 10, so that the battery 100 can be detachably connected to the vehicle beam 70. The detachable connection between the battery 100 and the vehicle beam 70 means that the battery 100 can be removed from the vehicle beam 70, and the removed battery 100 can also be reinstalled on the vehicle beam 70. The detachable connection method of the battery 100 can include at least one of a snap connection method and a fastener connection method. For example, the load-bearing bracket 10 can be detachably connected to the vehicle beam 70 by at least one of a snap connection method and a fastener connection method.

In the above technical solution, a load-bearing bracket 10 is provided for bearing the weight of the battery module 20 and the load-bearing bracket 10 is detachably connected to the vehicle beam 70, so that the replacement and maintenance of the battery 100 are convenient, and in the process of removing the battery 100 from the vehicle beam 70, the load-bearing bracket 10 can play a buffering and protective role for the battery 100, thereby reducing the damage to the battery 100 due to the large impact force under the action of its own gravity, and extending the service life of the battery 100; in addition, during the operation of the vehicle 1000, the impact force on the battery module 20 can be transmitted to the load-bearing bracket 10, so that the impact force on the battery module 20 can be dispersed and transmitted, thereby reducing or avoiding the damage to the battery module 20 due to the impact force, and extending the service life of the battery 100.

In some embodiments, referring to FIGS. 4-7 , the battery module 20 includes a housing 21 and at least one battery cell 221 . The battery cell 221 is disposed in the housing 21 . The housing 21 is detachably connected to the load-bearing bracket 10 .

The housing 21 of the battery module 20 defines a sealed accommodation cavity 201 , and the battery cell 221 is disposed in the sealed accommodation cavity 201 defined by the housing 21 , which can protect the battery cell 221 .

The shell 21 may be a metal part or a non-metal part. When the shell 21 is a metal part, an insulating structure may be provided between the battery cell 221 and the shell 21 to insulate and separate the battery cell 221 from the shell 21 .

The battery module 20 includes at least one battery cell 221, which means that a single battery module 20 may include one battery cell 221, and a single battery module 20 may also include multiple battery cells 221. When the battery module 20 includes multiple battery cells 221, the multiple battery cells 221 may be divided into at least one battery group 22, and the battery group 22 includes multiple battery cells 221 arranged side by side. When the battery module 20 includes multiple battery groups 22, the multiple battery groups 22 may be arranged in the horizontal direction, the multiple battery groups 22 may be arranged in the up-down direction, or the multiple battery groups 22 may be arranged in the horizontal direction and in the up-down direction.

In the above technical scheme, the battery module 20 can be sealed by its own outer shell 21, and the outer shell 21 of the battery module 20 is detachably connected to the load-bearing bracket 10, so that the detachable connection between the battery module 20 and the load-bearing bracket 10 can be easily realized, and the detachable connection between the outer shell 21 of the battery module 20 and the load-bearing bracket 10 can make the battery module 20 more reliably installed and fixed to the load-bearing bracket 10 compared with fixing the battery module 20 by pressing, and at the same time, it can also avoid the problem of extrusion damage to the battery module 20 caused by the pressing and fixing method.

In some embodiments, referring to Figures 5-7, the housing 21 includes a bottom plate 212 and a shell 211, the shell 211 is connected to the upper side of the bottom plate 212, and a receiving cavity 201 for accommodating a battery cell 221 is defined between the shell 211 and the bottom plate 212, and the bottom plate 212 is supported on the load-bearing bracket 10 and the bottom plate 212 is detachably connected to the load-bearing bracket 10.

The lower side of the shell 211 is open, and the bottom plate 212 is used to cover the lower side of the shell 211 , so that a closed accommodating cavity 201 can be defined between the shell 211 and the bottom plate 212 .

In the above technical solution, the battery module 20 is supported and connected to the load-bearing bracket 10 through its own bottom plate 212, so that the battery module 20 can be stably supported by the load-bearing bracket 10 and the battery module 20 can be more reliably fixed on the load-bearing bracket 10.

Optionally, the thickness of the base plate 212 can be greater than the thickness of the shell 211, so that the base plate 212 has a higher structural strength, can provide stable support for the battery cell 221, and can make the overall center of gravity of the battery module 20 lower, so that the battery module 20 is more stable as a whole after being installed on the load-bearing bracket 10.

In some embodiments, the projection of the housing 211 on the horizontal plane is the first projection, the projection of the bottom plate 212 on the horizontal plane is the second projection, and the first projection is located inside the second projection. The “first projection is located inside the second projection” means that the outer contour line of the first projection is located on the inner circumference of the outer contour line of the second projection.

In the above technical solution, since the projection of the shell 211 on the horizontal plane is located within the projection of the base plate 212 on the horizontal plane, the base plate 212 can be set larger, which can increase the supporting area of the load-bearing bracket 10 for the battery module 20, thereby further improving the stability of the load-bearing bracket 10 supporting the battery module 20.

In some embodiments, fasteners are disposed through the bottom plate 212 and the load-bearing bracket 10 to mount the battery module 20 on the load-bearing bracket 10 .

The fastener may be a threaded fastener, the fastener may be threadedly connected to the base plate 212 and the fastener may be threadedly connected to the load-bearing bracket 10 .

In the above technical solution, fasteners are passed through the base plate 212 and the load-bearing bracket 10, so as to realize the detachable connection between the battery module 20 and the load-bearing bracket 10. Through the connection method of the fasteners, the battery module 20 can be locked on the load-bearing bracket 10; and the connection method of the fasteners can not only realize the detachable connection between the battery module 20 and the load-bearing bracket 10, making it convenient to disassemble and assemble the battery module 20, but also ensure the installation stability and reliability of the battery module 20.

In some embodiments, referring to FIG. 5 and FIG. 6 , a connecting flange 2111 is formed on the lower edge of the housing 211 , and the connecting flange 2111 is detachably connected to the bottom plate 212 .

A sealing member may be provided at the connection between the connection flange 2111 of the housing 211 and the bottom plate 212 to achieve a sealed connection between the housing 211 and the bottom plate 212.

The “removable connection between the connecting flange 2111 and the bottom plate 212” means that the housing 211 can be separated from the bottom plate 212 to open the accommodating cavity 201, and the removed housing 211 can also be reinstalled on the bottom plate 212. The removable connection between the connecting flange 2111 and the bottom plate 212 can include at least one of a snap connection and a fastener connection.

By providing the locking accessory 164 on the top of the second support partition 14 instead of providing the locking accessory 164 on the top of the first support partition 13, the installation position of the locking accessory 164 of the battery 100 can be a more reliable and stable position of the load-bearing bracket 10, thereby improving the stability and reliability of the battery 100 installed on the vehicle beam 70.

Furthermore, since the battery modules 20 located at the upper layer are supported by a plurality of supporting partitions 12, the plurality of supporting partitions 12 can play a supporting role for the battery modules 20 located at the upper layer, and the loads received by the battery modules 20 located at the upper layer can be transmitted to the lower frame 11 through the plurality of supporting partitions 12, thereby reducing the impact on the battery modules 20 located at the upper layer, and also reducing the impact on the battery modules 20 located at the lower layer, thereby helping to extend the service life of the battery modules 20. In addition, by locating the locking parts 164 of the supporting partitions 12 between the adjacent battery modules 20 at the upper layer, the space between the adjacent battery modules 20 at the upper layer can be fully utilized, making the overall structure of the battery 100 compact, and also facilitating the locking and unlocking operations of the locking parts 164 and the beam 70, thereby facilitating the removal of the battery 100 from the beam 70 or the installation of the battery 100 on the beam 70.

In some embodiments, referring to FIGS. 1-4 , the docking device 52 is located at the top of the battery 100. By arranging the docking device 52 at the top of the battery 100, when the battery 100 is installed on the vehicle beam 70, it is convenient to dock the docking device 52 with the corresponding structure on the vehicle body 200, so that the docking device 52 and the vehicle body 200 can be conveniently electrically connected; and when the battery 100 is removed from the vehicle beam 70, it is also convenient to separate the docking device 52 from the corresponding structure on the vehicle body 200.

In some embodiments, referring to FIG. 1 to FIG. 4 , the docking port 521 of the docking connector 52 faces upward. By arranging the docking connector 52 on the top of the battery 100, when the battery 100 is installed on the vehicle beam 70, the docking connector 52 docks with the corresponding structure on the vehicle body 200 in the up-down direction, so that the docking connector 52 and the vehicle body 200 can be easily electrically connected; and when the battery 100 is removed from the vehicle beam 70, the docking connector 52 and the corresponding structure on the vehicle body 200 are separated in the up-down direction, which also facilitates the separation of the docking connector 52 and the corresponding structure on the vehicle body 200.

By arranging the docking device 52 in the middle of the load-bearing bracket 10 along the width direction of the vehicle beam 70, the influence of vibration impact or natural load-bearing deformation on the docking device 52 can be reduced.

In some embodiments, referring to FIGS. 2-5 , the battery 100 includes: a distribution box 50 , the distribution box 50 is disposed on the load-bearing bracket 10 , and a docking device 52 is disposed on the distribution box 50 .

The distribution box 50 and the docking device 52 provided in the distribution box 50 are components for electrically connecting the battery 100 and the vehicle body 200, so that the battery 100 can supply power to the vehicle body 200.

For example, some of the battery modules 20 are detachably connected to the distribution box 50 via a connecting harness, or each battery module 20 is detachably connected to the distribution box 50 via a connecting harness.

Among them, the battery module 20 detachably connected to the load-bearing bracket 10 (referring to the battery module 20 detachably connected to the load-bearing bracket 10) is detachably connected to the distribution box 50 through a connecting harness.

In the above technical solution, a detachable connection between at least part of the battery module 20 and the distribution box 50 is achieved by connecting the wiring harness, which not only enables the disassembly of the mechanical connection structure of the battery module 20, but also enables the disassembly of the electrical connection structure of the battery module 20, so that the battery module 20 can be removed smoothly as a whole.

In some embodiments, referring to Figures 2-5, at least part of the battery modules 20 have a first interface 23, the distribution box 50 has a second interface 51, the two ends of the connecting harness are respectively connected to the first interface 23 and the second interface 51, and the connecting harness is detachably connected to at least one of the first interface 23 and the second interface 51.

Among them, a single battery module 20 may have two first interfaces 23, one of the two first interfaces 23 is a positive electrode and the other of the two first interfaces 23 is a negative electrode. The number of second interfaces 51 of the distribution box 50 is an even number, and the distribution box 50 has at least one pair of second interfaces 51, one of the pair of second interfaces 51 is a positive electrode and the other is a negative electrode. The first interface 23 of the battery module 20 and the second interface 51 of the distribution box 50 can be connected according to the connection method requirements of the series-parallel relationship of the multiple battery modules 20.

For example, all battery modules 20 are connected in parallel, and the first interface 23 as the positive pole in each battery module 20 is connected to the second interface 51 as the positive pole in the distribution box 50 through a connecting harness, and the first interface 23 as the negative pole in each battery module 20 is connected to the second interface 51 as the negative pole in the distribution box 50 through a connecting harness.

The detachable connection between the connecting harness and at least one of the first interface 23 and the second interface 51 may include the following situations: for example, the connecting harness may be detachably connected to the first interface 23, so that the battery module 20 and the distribution box 50 may be detachably connected through the connecting harness by connecting the connecting harness to the first interface 23 or removing it from the first interface 23; for another example, the connecting harness may be detachably connected to the second interface 51, so that the battery module 20 and the distribution box 50 may be detachably connected through the connecting harness by connecting the connecting harness to the second interface 51 or removing it from the second interface 51; for another example, the connecting harness may be detachably connected to the first interface 23 and the connecting harness may be detachably connected to the second interface 51, so that the battery module 20 and the distribution box 50 may be detachably connected through the connecting harness by connecting the connecting harness to the first interface 23 or removing it from the first interface 23, or by connecting the connecting harness to the second interface 51 or removing it from the second interface 51.

In the above technical solution, by providing interfaces between the battery module 20 and the distribution box 50, the connection and separation between the battery module 20 and the distribution box 50 are further facilitated.

In some embodiments, referring to FIGS. 2-5 , the distribution box 50 has a plurality of second interfaces 51 , and all the second interfaces 51 are located on the same side of the distribution box 50 .

All the second interfaces 51 are located on the same side of the distribution box 50 , which means that all the second interfaces 51 are located on the same side of the distribution box 50 along the horizontal direction.

In the above technical solution, by setting multiple second interfaces 51 on the distribution box 50 on the same side of the distribution box 50, multiple connection harnesses of multiple battery modules 20 can be conveniently connected to the same side of the distribution box 50, making it convenient to disassemble and assemble the connection harnesses and also convenient to maintain.

In some embodiments, referring to FIGS. 2-5 , the distribution box 50 is integrated with one of the battery modules 20 .

The power distribution box 50 and one of the battery modules 20 are integrated into one, which means that the power distribution box 50 and one of the battery modules 20 are integrated into an integral structure.

In the above technical solution, by integrating the distribution box 50 with one of the battery modules 20, the structure can be made compact, the occupied space can be reduced, and the overall energy density of the battery 100 can be improved.

In some embodiments, referring to Figures 1-4, the multiple battery modules 20 include a first battery module 30 and a second battery module 40, there is at least one first battery module 30, and there is one second battery module 40. The first battery module 30 and the distribution box 50 are detachably connected via a connecting harness, and the distribution box 50 and the second battery module 40 are integrated into one.

There is at least one first battery module 30 , which means there can be one first battery module 30 , or there can be multiple first battery modules 30 . Among them, at least one first battery module 30 can be detachably mounted on the load-bearing bracket 10 .

It is understandable that since the distribution box 50 is integrated with the second battery module 40 , the second battery module 40 may not be provided with the above-mentioned first interface 23 , and the battery cells 221 of the second battery module 40 may be directly electrically connected to the distribution box 50 inside the second battery module 40 .

The distribution box 50 and the second battery module 40 are integrated as one, which means that the distribution box 50 and the second battery module 40 are integrated into an integral structure. The second battery module 40 can be detachably mounted on the load-bearing bracket 10. Since the distribution box 50 and the second battery module 40 are integrated as one, the distribution box 50 and the second battery module 40 can be removed from the load-bearing bracket 10 as a whole, or the distribution box 50 and the second battery module 40 can be installed on the load-bearing bracket 10 as a whole.

In some embodiments, referring to Figures 2-5, the battery module 20 includes a shell 21 and a battery cell 221 disposed in the shell 21, the shell 21 of the first battery module 30 is provided with a first interface 23, the distribution box 50 includes a box body and an electrical component disposed in the box body, the shell 21 of the second battery module 40 constitutes the box body and the shell 21 of the second battery module 40 is provided with a second interface 51, the electrical component is electrically connected to the second interface 51, the two ends of the connecting harness are respectively connected to the first interface 23 and the second interface 51, the connecting harness is detachably connected to at least one of the first interface 23 and the second interface 51, and the battery cell 221 of the second battery module 40 is electrically connected to the electrical component.

The outer shell 21 of the second battery module 40 constitutes a box body, and part of the outer shell 21 of the second battery module 40 may constitute the box body.

The second interface 51 is electrically connected to the electrical components. For example, the second interface 51 and the electrical components can be electrically connected through an internal wiring harness. The internal wiring harness is routed inside the box. The battery cells 221 of the second battery module 40 and the electrical components of the distribution box 50 are both located inside the outer shell 21 of the second battery module 40. In this way, the battery cells 221 of the second battery module 40 or a battery pack composed of multiple battery cells 221 can be directly electrically connected to the electrical components inside the outer shell 21 of the second battery module 40.

The electrical connection between the first battery module 30 and the distribution box 50 is achieved by connecting the first interface 23 and the second interface 51 through a connecting harness. It should be noted that the connection between the multiple first battery modules 30 and the first battery module 30 and the distribution box 50 can be determined according to the series-parallel mode of the multiple battery modules 20. For example, some of the first battery modules 30 can be connected in series and then electrically connected to the distribution box 50.

For example, when the battery 100 includes multiple first battery modules 30 and one second battery module 40, the multiple battery modules 20 of the battery 100 can be connected in series and parallel as follows: the multiple first battery modules 30 are divided into multiple module groups, the second battery module 40 includes multiple battery cells 221, and the multiple second battery cells 221 of the second battery module 40 are divided into multiple battery groups. The number of module groups is the same as the number of battery groups and corresponds one to one. Each module group includes multiple battery modules 20. After the multiple battery modules 20 of each module group are connected in series in sequence, the first interface 23 and the second interface 51 of the distribution box 50 are connected by connecting the wiring harness, so that the module group and the distribution box 50 can be electrically connected. The multiple battery groups of the second battery module 40 are all electrically connected to the electrical components of the distribution box 50, and through circuit design, each module group is connected in series with the corresponding battery group to form a battery branch, thereby forming multiple battery branches connected in parallel.

In the above technical scheme, since the second battery module 40 is integrated with the distribution box 50, the structure is compact, the occupied space is reduced, and it is beneficial to improve the overall energy density of the battery 100. At the same time, by making the distribution box 50 share the outer shell 21 of the second battery module 40 to achieve sealing of the distribution box 50, it is possible to eliminate the need to set up a separate box body for the distribution box 50, reduce the number of parts, and further make the structure compact, further reducing the occupied space; in addition, the battery cells 221 in the second battery module 40 can be electrically connected to the electrical components of the distribution box 50 in the outer shell 21 of the second battery module 40, thereby eliminating the need to set an interface for connecting the distribution box 50 on the outside of the second battery module 40.

Among them, the thermal management component 24 is used to adjust the temperature of the battery cell 221, including at least one of the thermal management component 24 being used to increase the temperature of the battery cell 221 and being used to reduce the temperature of the battery cell 221. For example, the thermal management component 24 can be used to increase the temperature of the battery cell 221 and can be used to reduce the temperature of the battery cell 221.

The thermal management component 24 is used to adjust the temperature of the battery cell 221 . The thermal management component 24 can be in thermal contact with the battery cell 221 , so that the thermal management component 24 can adjust the temperature of the battery cell 221 .

Optionally, the number of thermal management components 24 is the same as the number of battery modules 20 and corresponds one to one.

In the above technical solution, by setting up a thermal management system including multiple thermal management components 24, the temperature of each battery module 20 can be regulated. By setting the thermal management component 24 in the outer shell 21 of the battery module 20, so that the battery module 20 has a separate thermal management component 24, the temperature regulation efficiency of the thermal management component 24 on the battery cells 221 of the battery module 20 can be improved, and the maintenance of the battery module 20 is also convenient.

In some embodiments, referring to FIGS. 5-7 , the thermal management component 24 is integrated into the housing 21 .

The thermal management component 24 may be integrated into the housing 21 , which means that the thermal management component 24 and the housing 21 are integrated into a whole.

In the above technical solution, the thermal management component 24 is integrated into the housing 21 , which can make the structure of the battery module 20 compact, reduce the occupied space, and help improve the energy density of the single battery module 20 .

In some embodiments, the housing 21 includes a base plate 212 and a shell 211, the shell 211 is connected to the upper side of the base plate 212, and a receiving cavity 201 for accommodating a battery cell 221 is defined between the shell 211 and the base plate 212, the base plate 212 is supported on a load-bearing bracket 10, and the thermal management component 24 is integrated in the base plate 212.

The thermal management component 24 is integrated with the bottom plate 212, which means that the thermal management component 24 and the bottom plate 212 are integrated into one body, and the thermal management component 24 and the bottom plate 212 can jointly support the battery cells 221 of the battery module 20. For example, the bottom plate 212 can have a hollow structure, and the hollow structure in the bottom plate 212 can include the above-mentioned heat exchange channel.

In the above technical solution, the battery module 20 is supported and connected to the load-bearing bracket 10 through its own base plate 212, so that the battery module 20 can be stably supported by the load-bearing bracket 10, and the battery module 20 can be more reliably fixed on the load-bearing bracket 10; and the thermal management component 24 is integrated into the base plate 212 to improve the structural strength of the base plate 212, so that the base plate 212 can better support the battery cells 221 located in the outer shell 21, and the overall center of gravity of the battery module 20 is lowered, so that the overall structure of the battery module 20 is more stable, and the battery module 20 can be more stably installed on the load-bearing bracket 10.

In some embodiments, referring to FIGS. 5-7 , the thermal management component 24 is integrally formed with the base plate 212 .

The thermal management component 24 and the bottom plate 212 are integrally formed, which means that the thermal management component 24 and the bottom plate 212 are an integrated structure, and there is no boundary line or interface between the thermal management component 24 and the bottom plate 212 .

For example, the thermal management component 24 and the base plate 212 may be integrally cast.

In the above technical solution, by integrally forming the thermal management component 24 and the bottom plate 212 of the battery module 20, the number of parts can be reduced, the assembly process of the thermal management component 24 and the bottom plate 212 can be omitted, and the production efficiency can be improved.

In some embodiments, referring to Figure 2, the thermal management component 24 has a heat exchange channel for the flow of heat exchange medium, and multiple thermal management components 24 are connected in series, parallel or mixed. The thermal management system also includes a thermal management connector 60, which is used to realize the thermal management flow path connection between the battery 100 and the vehicle body 200. The thermal management connector 60 is arranged on the load-bearing bracket 10 and is located outside the battery module 20. At least part of the thermal management components 24 are connected to the thermal management connector 60.

The heat management component 24 has a heat exchange channel for the heat exchange medium to flow, and during the flow of the heat exchange medium in the heat exchange channel, the heat exchange medium can take away the heat of the battery cell 221, or the heat exchange medium can transfer the heat to the battery cell 221 to heat the battery cell 221. The heat exchange medium can be a liquid heat exchange medium, for example, the heat exchange medium can include water.

The thermal management joint 60 may have two liquid inlets and outlets 61. The heat exchange medium flows into the thermal management joint 60 from one of the two liquid inlets and outlets 61, flows through the heat exchange channel, and then flows into the thermal management joint 60, and may flow out through the other of the two liquid inlets and outlets 61. When the thermal management joint 60 is connected to the thermal management flow path of the vehicle body 200 to form a circulation flow path, the two liquid inlets and outlets 61 of the thermal management joint 60 are connected to the thermal management flow path of the vehicle body 200 to form a circulation flow path.

When multiple thermal management components 24 are connected in series, the heat exchange medium flowing in from the thermal management joint 60 can flow through the multiple thermal management components 24 in sequence, and then flow out from the thermal management joint 60; when multiple thermal management components 24 are connected in parallel, the heat exchange medium flowing in from the thermal management joint 60 can flow through the multiple thermal management components 24 at the same time, and finally gather at the thermal management joint 60 before flowing out; when multiple thermal management joints 60 are mixed in series, for example, multiple thermal management joints 60 are divided into multiple thermal management groups, each thermal management group includes multiple thermal management components 24 connected in series, the heat exchange medium flowing in from the thermal management joint 60 can flow through the multiple thermal management groups at the same time, and when flowing through each thermal management group, it can flow through the multiple thermal management components 24 in each thermal management group in sequence, and finally gather at the thermal management joint 60 before flowing out.

In the above technical solution, the thermal management flow path connection between the battery 100 and the vehicle body 200 is realized by multiple thermal management components 24 sharing a thermal management connector 60, and the heat exchange medium can flow into or out of multiple thermal management components 24 through a common thermal management connector 60, so that the thermal management system is connected to the thermal management flow path of the vehicle body 200 through a common thermal management connector 60 to realize the circulation flow of the heat exchange medium.

In some embodiments, referring to FIG. 2 , the thermal management joint 60 is located near the outer edge of the load-bearing bracket 10 .

The outer edge of the load-bearing bracket 10 refers to the outer edge of the load-bearing bracket 10 in the horizontal direction.

The pipe joint 241 and the heat management joint 60 are both detachably connected via a first connecting pipe and/or the pipe joints 241 between the heat management components 24 are detachably connected via a second connecting pipe.

When the heat exchange medium flows through a single battery module 20 for temperature adjustment, the heat exchange medium flows into the heat exchange channel from one of the two pipe joints 241 , and flows out from the other of the two pipe joints 241 after flowing through the heat exchange channel.

It should be noted that the pipe joint 241 and the thermal management joint 60 are both detachably connected via a first connecting pipe, thereby realizing a detachable connection between the thermal management component 24 and the thermal management joint 60; the pipe joints 241 between the thermal management components 24 are detachably connected via a second connecting pipe, thereby realizing a detachable connection between the thermal management components 24. When at least some of the thermal management components 24 are connected in series, one end of the second connecting pipe is connected to the pipe joint 241 of one of the two adjacent thermal management components 24 (for example, the pipe joint 241 serves as a liquid inlet joint) and the other end of the second connecting pipe is connected to the pipe joint 241 of the other of the two adjacent thermal management components 24 (for example, the pipe joint 241 serves as a liquid outlet joint).

Among them, the detachable connection between the first connecting pipe and the pipe joint 241, the detachable connection between the first connecting pipe and the thermal management joint 60, and the detachable connection between the second connecting pipe and the pipe joint 241 can all be plug connections.

In the above technical solution, two pipe joints 241 connected to the heat exchange channel of the thermal management component 24 are arranged on the outer wall of the shell 21, so as to facilitate the connection and separation between the thermal management component 24 and the thermal management joint 60 or the connection or separation between the thermal management components 24.

In some embodiments, referring to FIGS. 5-7 , the two pipe joints 241 of the same battery module 20 are located on the same side of the battery module 20 .

The two pipe joints 241 of the same battery module 20 are located on the same side of the battery module 20, which means that the two pipe joints 241 of the same battery module 20 are located on the same side of the battery module 20 along the horizontal direction.

Thus, when the battery 100 is installed on the vehicle beam 70, the space between the beam bodies of the vehicle beam 70 can be fully utilized to achieve the purpose of avoiding the vehicle beam 70, making the structure compact.
