DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

In the embodiments of the present application, words such as "exemplarily" or "for example" are used to represent examples, illustrations, or explanations.

Rather, the use of words such as "exemplarily" or "for example" is intended to present relevant concepts in a specific manner.

[0032] Unless otherwise specified, the term "plurality" means two or more.

[0033] As described in the background art, significant progress has been made in the research and development and application of the three key components (motor, battery, and electronic control) technology of electric vehicles, which has promoted the improvement of the performance and endurance of electric vehicles. Among them, as the "heart" of electric vehicles, the technological innovation and structural optimization of power batteries are particularly crucial. In recent years, in order to improve the energy density, reduce the system weight and cost, the design of power battery packs has gradually changed from the traditional module-to-pack (MTP) structure to the cell-to-pack (CTP) structure. The CTP technology directly integrates the cells into the battery pack by omitting the module design, effectively reducing the intermediate links and improving the space utilization rate and energy density.

[0034] However, there are still certain technical problems in the design and production process of CTP battery modules. For example, when assembling a CTP battery module with multiple battery groups, epoxy boards are used as bonding materials to bond the side end faces of two or more battery groups to form a stable overall structure and then place it in the battery box. However, as the number of battery groups increases, the number of required epoxy boards also doubles, resulting in a significant increase in the overall weight. In addition, this method of bonding multiple battery groups into a whole and then placing them in the battery box increases the difficulty of handling and moving the battery groups and inserting the battery groups into the box, thereby affecting the assembly efficiency of the CTP battery module and lengthening the production cycle of the CTP battery module.

[0035] To solve the above problems, an embodiment of the present application provides a CTP battery module, including a box body, a battery pack, and a partition. First, multiple groups of battery packs are placed in the box body. The bonding part of the partition is coated with structural adhesive. Then, the main body part of the partition is inserted into the gap between two adjacent groups of battery packs. When the main body part is inserted in place, the bonding part can be bonded to the opposite end faces of the two battery packs through the structural adhesive. Thus, the lateral connection of two adjacent battery packs is realized through the partition, improving the lateral stiffness of the battery pack. In addition, it is not necessary to place multiple groups of battery packs in the box body as a whole at the same time, reducing the difficulty of putting the battery packs into the box and ensuring the assembly efficiency of the CTP battery module.

[0036] The following uses specific embodiments to elaborate in detail on the technical solutions of the embodiments of the present application and how the technical solutions of the embodiments of the present application solve the above technical problems. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following will describe the embodiments of the present application with reference to the accompanying drawings.

[0037] Refer to Figures 1 to 5 As shown in

[0038] Among them, the box body is provided with a receiving cavity, the battery pack 1 is placed in the receiving cavity, and at least two groups of battery packs 1 are configured; the partition 2 includes a main body part 21 and two bonding parts 22. Along the first direction, the projection profile of the main body part 21 is in a T shape. One end of the main body part 21 is inserted into the gap between two adjacent groups of battery packs 1, and the other end of the main body part 21 is in contact with the upper end faces of the two groups of battery packs 1. The two bonding parts 22 are respectively arranged at both ends of the main body part 21 along the second direction. One end of each of the two bonding parts 22 is connected to the main body part 21, and the other end of the two bonding parts 22 corresponds to the two opposite end faces of the two groups of battery packs 1 one by one. The bonding part 22 is coated with structural adhesive, and the bonding part 22 is bonded to the end face of the battery pack 1 through the structural adhesive. The second direction is perpendicular to the first direction.

[0039] Specifically, when assembling the CTP battery module, the installation steps of the battery pack 1 are as follows: First, place multiple battery packs 1 in the accommodation cavity in the box in sequence, and space the multiple battery packs 1 apart to reserve the installation space for the partition 2; after all the battery packs 1 are placed in the box, apply structural adhesive to the bonding part 22 of the partition 2, insert the main body part 21 of the partition 2 into the gap between adjacent battery packs 1. After the main body part 21 is inserted to the predetermined position, the free ends of the two bonding parts 22 are bonded to the two opposite end faces of the adjacent two battery packs 1. Since one end of each of the two bonding parts 22 is connected to the main body part 21, the adjacent two battery packs 1 can be connected into a whole through the partition 2, thereby strengthening the lateral stiffness of the battery pack 1 and ensuring the fixing effect of the battery pack 1 in the box, and further ensuring the service life of the CTP battery module. In addition, compared with the prior art method of adhesively bonding multiple groups of battery packs with an epoxy board and then placing them in the box as a whole, the CTP battery module in this embodiment places multiple groups of battery packs 1 in the box in sequence, which can effectively reduce the weight and difficulty of the battery packs 1 entering the box, and further improve the assembly efficiency of the CTP battery module.

[0040] Exemplarily, in this embodiment, the length direction of the battery pack 1 is defined as the first direction, and the width direction of the battery pack 1 is defined as the second direction.

[0041] Optionally, in this embodiment, the number of the battery packs 1 is not specifically limited and can be increased or decreased according to actual needs. For example, the number of the battery packs 1 can be three groups, four groups, five groups, etc. Further, when the number of the battery packs 1 is greater than two groups, the number of the partitions 2 is adaptively increased, so that multiple groups of battery packs 1 are adhesively bonded into a whole in the box through multiple partitions 2 to increase the lateral stiffness of the battery packs 1 in the box and ensure the fixing effect of multiple groups of battery packs 1 in the box.

[0042] It should be noted that in this embodiment, the main body part 21 of the partition 2 is set to be T-shaped, which is convenient for inserting the partition 2 into the gap between the battery packs 1, and the upper end of the T-shape can fit with the upper end face of the battery pack 1, so that it can play a role in limiting when inserting the main body part 21.

[0043] Reference Figure 1 and Figure 3 As shown in [references], in an optional embodiment, the bonding part 22 is composed of multiple fins, and the multiple fins all extend along the first direction and are spaced apart along the third direction, and the third direction is perpendicular to both the first direction and the second direction.

[0044] Exemplarily, in this embodiment, the height direction of the battery pack 1 is defined as the third direction.

[0045] Specifically, in this embodiment, the bonding portion 22 is composed of a plurality of fins. The plurality of fins extend in the first direction, and the plurality of fins are spaced apart in the third direction. By setting the bonding portion 22 as fins, it is possible to ensure that there is a long continuous bonding area between the bonding portion 22 and the end face of the battery pack 1, thereby ensuring the bonding effect between the bonding portion 22 and the end face of the battery pack 1; by spacing the plurality of fins in the third direction, the fins can be adhesively adhered to the end face of the battery pack 1 uniformly, ensuring the uniformity and reliability of the adhesion between the bonding portion 22 and the end face of the battery pack 1.

[0046] Optionally, a material capable of elastic deformation is selected as the material of the fins. Before the partition 2 is inserted into the gap between two adjacent battery packs 1, along the second direction, the linear distance value of the two groups of fins provided at both ends of the main body portion 21 at the end far from the main body portion 21 is greater than the gap value between the two battery packs 1; thus, when the partition 2 is inserted into the gap between two adjacent battery packs 1, the fins will abut against the end face of the battery pack 1 and then undergo elastic deformation. Such a setting can ensure that the fins are better adhesively bonded to the end face of the battery pack 1.

[0047] Optionally, when applying the structural adhesive, the structural adhesive is applied to the upper end face of each fin and the outer edge on the side far from the main body portion 21.

[0048] Reference Figure 4 and Figure 5 As shown in, in an alternative embodiment, the bonding portion 22 is composed of a plurality of bonding columns, and the plurality of bonding columns are arranged in an array.

[0049] Specifically, in this embodiment, the bonding portion 22 is composed of a plurality of bonding columns, and the plurality of bonding columns are arranged in an array. By arranging the bonding columns in an array, each bonding column can serve as an independent bonding area, thereby ensuring the bonding effect between the bonding portion 22 and the end face of the battery pack 1 by multiple bonding areas. In addition, this multi-area bonding connection method can also effectively resist the impact and vibration of external forces.

[0050] In addition, the bonding columns arranged in an array can disperse the stress generated during the use of the battery module more evenly. When the battery module is subjected to an external force, the stress will be dispersed to a plurality of bonding columns, thereby avoiding damage caused by single-point stress concentration.

[0051] Optionally, a material capable of elastic deformation is selected as the material of the bonding columns. Before the partition 2 is inserted into the gap between two adjacent battery packs 1, along the second direction, the linear distance value of the bonding columns provided at both ends of the main body portion 21 at the end far from the main body portion 21 is greater than the gap value between the two battery packs 1; thus, when the partition 2 is inserted into the gap between two adjacent battery packs 1, the bonding columns will abut against the end face of the battery pack 1 and then undergo elastic deformation. Such a setting can ensure that the bonding columns are better adhesively bonded to the end face of the battery pack 1.

[0052] Optionally, in this embodiment, the bonding posts are provided in a cylindrical structure. Of course, in other embodiments, the bonding posts can also be provided in other shapes, such as a triangular prism structure, a quadrangular prism structure, or a hexagonal prism structure, etc.

[0053] Optionally, the number, size, and distribution of the bonding posts can be adjusted according to the specific requirements and dimensions of the battery module to meet the installation requirements of different battery packs 1.

[0054] Optionally, the bonding portion 22 is composed of a plurality of bonding blocks, and the plurality of bonding blocks are arranged in an array. Specifically, the function of the bonding blocks is the same as that of the above-mentioned fins and bonding posts. Therefore, the function of the bonding blocks will not be described in detail.

[0055] In an alternative embodiment, the material of the bonding portion 22 is a soft plastic.

[0056] Specifically, a soft plastic is selected as the material of the bonding portion 22. The soft plastic has excellent flexibility and elasticity. Thus, when the bonding portion 22 abuts against the end face of the battery pack 1, elastic deformation can occur, ensuring that the bonding portion 22 and the battery pack 1 can be closely attached, so that the bonding effect between the bonding portion 22 and the end face of the battery pack 1 is better. In addition, the soft plastic also enables the bonding portion 22 to provide a better buffering effect, reducing stress concentration caused by vibration or impact.

[0057] Optionally, in this embodiment, the material of the bonding portion 22 is a soft plastic, such as polyethylene, polyvinyl chloride, or polypropylene, etc. The material of the main body portion 21 can be the same as or different from that of the bonding portion 22. In this embodiment, the material of the main body portion 21 is not limited. It should also be noted that when selecting a soft plastic as the material of the bonding portion 22, its performance indicators such as temperature resistance, corrosion resistance, and aging resistance need to be considered to ensure that it can meet the usage requirements of the battery module.

[0058] In an alternative embodiment, the main body portion 21 and the bonding portion 22 are integrally formed structures.

[0059] Specifically, integrally forming the main body portion 21 and the bonding portion 22 can ensure the overall structural strength of the partition 2 and guarantee the connection effect of the partition 2 on two adjacent battery packs 1.

[0060] Of course, in other embodiments, the main body portion 21 and the bonding portion 22 can also be provided in a detachable connection manner. Thus, the manufacturing difficulty of integrally forming the main body portion 21 and the bonding portion 22 can be reduced. In addition, it is also convenient to select different materials to produce the main body portion 21 and the bonding portion 22, so that the partition 2 can better connect two adjacent battery packs 1.

[0061] In an alternative embodiment, one end of the main body portion 21 that fits against the upper end surface of the battery pack 1 is coated with structural adhesive, and the main body portion 21 and the upper end surface of the battery pack 1 are bonded together by the structural adhesive.

[0062] Specifically, before inserting the partition 2 into the gap between adjacent battery packs 1, structural adhesive is coated on the main body portion 21. Thus, when the partition 2 is inserted to the predetermined position, the main body portion 21 is bonded to the upper end surface of the battery pack 1 through the structural adhesive. With such an arrangement, the connection between the partition 2 and the adjacent two battery packs 1 can be made more firm.

[0063] Optionally, structural adhesive is coated on the upper end surface of the battery pack 1 to bond the main body portion 21 to the upper end surface of the battery pack 1. It should also be noted that, in order to ensure the bonding quality, the upper end surface of the main body portion 21 and the battery pack 1 need to be cleaned before coating the structural adhesive to remove impurities such as oil stains and dust. At the same time, the coating amount and uniformity of the structural adhesive also need to be controlled to avoid problems such as poor bonding or glue overflow.

[0064] In an alternative embodiment, the bottom wall of the accommodation cavity and / or the bottom of the battery pack 1 is coated with structural adhesive, and the battery pack 1 is bonded to the bottom wall of the accommodation cavity through the structural adhesive.

[0065] Specifically, before the battery pack 1 is placed in the accommodation cavity of the box body, the bottom wall of the accommodation cavity and / or the bottom of the battery pack 1 is coated with structural adhesive. Thus, the battery pack 1 can be fixedly bonded in the accommodation cavity through the structural adhesive, improving the seismic performance of the battery pack 1. With such an arrangement, the stability of the battery pack 1 in the accommodation cavity can be ensured, and the situation where the battery pack 1 shakes or shifts during use can be avoided.

[0066] Optionally, a structural adhesive with good thermal conductivity is selected to bond the battery pack 1. Thus, the heat generated when the battery pack 1 is working can be transferred to the bottom wall of the accommodation cavity through the structural adhesive, improving the heat dissipation performance of the battery module.

[0067] Optionally, the battery pack 1 can also be fixedly connected to the bottom wall of the accommodation cavity by means of bolt connection or snap connection.

[0068] In an alternative embodiment, the CTP battery module further includes: a tray, the tray is installed on the upper end surface of the battery pack 1, the tray is used to support the electrode plate, the tray is provided with a groove, and one end of the main body portion 21 that fits against the upper end surface of the battery pack 1 can be inserted into the groove.

[0069] Specifically, the CTP battery module further includes a tray. After the partition 2 is installed, the tray is installed on the upper end surface of the battery pack 1. After the tray is installed, the pole pieces are welded so that multiple battery packs 1 can be connected in series as a whole. The tray serves to support and fix the pole pieces. In addition, in order to accommodate the setting of the partition 2, the tray is also provided with a groove. Thus, when the tray is installed on the upper end surface of the battery pack 1, one end of the main body 21 of the partition 2 that fits the upper end surface can be arranged in the groove, serving to avoid the main body 21 of the partition 2.

[0070] In addition, the groove can also serve to position the installation position of the tray, so as to improve the installation efficiency of the tray.

[0071] It should also be noted that in this embodiment, the size and shape of the groove are not limited, as long as it can achieve the function of avoiding the main body 21 of the partition 2.

[0072] The embodiment of the present application also provides an electric vehicle, including a vehicle body structure and the above-mentioned CTP battery module. The CTP battery module is fixedly installed on the vehicle body structure and is used to supply power to the electric vehicle. The CTP battery module connects adjacent battery packs 1 through the partition 2, ensuring the lateral stiffness of the battery packs 1 in the battery box, and further ensuring that the CTP battery module can stably supply power to the electric vehicle.
