[0029] In some embodiments, the material of the end plate 11 is aluminum alloy, i.e., the material of the first end plate 111 and / or the end plate 112 is aluminum alloy. With the above technical scheme, the lightweight of the CTP battery pack 100 can be realized under the condition of high mechanical strength.

[0030] The design of the first end plate 111, the second end plate 112, the bottom plate 17, the cross beam 15, and the top plate 2 cancels the traditional module frame and bolt connection, so that the battery cell 3 is directly connected with the battery pack bottom plate 17 and the first end plate 111 and the second end plate 112, greatly simplifying the structure. Not only the number of parts is reduced, the assembly complexity is reduced, but also the assembly efficiency is improved to a certain extent. At the same time, the firmness and the shock resistance are improved. The CTP battery pack adopts an overall frame design, and through the cooperation of the bottom plate 17, the first end plate 111, the second end plate 112, the first side plate 161, the second side plate 162, the top plate 2, and the cross beam 15, a stable structural system is formed. Compared with the traditional bolt fixing mode, the rigidity of the CTP battery pack is greatly improved, the vibration and impact are effectively coped with, and the risk of bolt loosening is reduced. Through the simplification of the structure and the optimization of the installation process, the materials of the bottom plate, the module end plate, and the module side plate used by the module are reduced, the manufacturing efficiency of the CTP battery pack is improved, the manufacturing and maintenance costs are reduced, and the scale production and application are faster.

[0031] The first end plate 111 and the second end plate 112 are arranged at two ends of the battery cell group 03, and a longitudinal structural frame is formed through connection with the first side plate 161 and the second side plate 162; the top plate 2 is connected with the first side plate 161 and the second side plate 162 through the first end plate 111 and the second end plate 112, and the bending resistance and the compression resistance of the battery pack as a whole are increased. The CTP battery pack is provided with the cross beam 15 extending along the second direction X.

The reinforcing rib 10 can enhance the mechanical strength of the bottom plate 17, so that the bottom plate 17 is more solid when bearing external loads (such as vibration, impact, etc.), and is not easy to deform. The reinforcing rib 10 provides additional support for the battery cell 3, which helps to keep the battery cell 3 in a fixed position and prevent the battery cell 3 from shifting due to vibration during transportation or use. The reinforcing rib 10 helps to disperse external impact force, especially improves the ball impact resistance of the bottom plate 17, which can reduce the risk of damage to the bottom plate 17 and improve the overall impact resistance of the CTP battery pack 100. By arranging the reinforcing rib 10 on the bottom plate 17, the amount of bottom plate material can be reduced while maintaining structural strength, thereby reducing overall weight and improving the energy density of the CTP battery pack 100.

[0035] By adopting the above technical solution, the overall structural strength, stability and safety of the CTP battery pack can be improved while reducing weight, supporting the battery cell 3, and improving the ball impact resistance and impact resistance of the bottom plate 17 while reducing the weight of the CTP battery pack 100.

[0036] In some embodiments, the 45 battery cells 3 share one top plate 2, thereby improving the mechanical strength of the CTP battery pack and reducing the amount of top plate material.

[0037] According to another specific embodiment of the present application, as shown in Figure 1 The cross beam 15 separates the battery cell group 03 into a first battery cell group 031 and a second battery cell group 032, and is located between the first battery cell group 031 and the second battery cell group 032. The first battery cell group 031 and the second battery cell group 032 are arranged along the first direction X and abut against the cross beam 15. By arranging the first battery cell group 031 and the second battery cell group 032 along the first direction X and abutting against the cross beam 15, the cross beam 15 can extrude the first battery cell group 031 and the second battery cell group 032, thereby playing a role in firmly fixing the battery cell 3.

[0038] The extrusion of the cross beam 15 on the first battery cell group 031 and the second battery cell group 032 plays a role in fixing and protecting the battery cell 3, and at the same time applies pressure to the battery cell 3, which can effectively stabilize the position of each battery cell 3 and prevent the battery cell 3 from shifting due to vibration during transportation or use. By extruding the battery cell group 03, the cross beam 15 helps to improve the structural stability of the entire CTP battery pack 100, so that it maintains the integrity of the overall structure when subjected to external impact or vibration. The presence of the cross beam 15 reduces the relative displacement between the battery cells 3, which helps to maintain the reliability of the connection of the battery cells 3 and reduces the risk of connection failure caused by displacement of the battery cells 3. The structural design of the cross beam 15 helps to disperse and absorb external impact force, thereby improving the impact resistance of the CTP battery pack 100. The structural design of the cross beam 15 significantly increases the mechanical strength of the battery pack, allowing a more compact battery cell layout, thereby improving the utilization efficiency of the internal space of the battery pack and increasing the energy density.

[0039] The above technical solution can improve the stability of the CTP battery pack 100, improve the structural stability of the CTP battery pack 100, reduce the relative displacement between the battery cells 3, improve the impact resistance of the CTP battery pack 100, increase the mechanical strength of the CTP battery pack 100, improve the space utilization, improve the energy density of the CTP battery pack, and simplify the assembly and maintenance.

[0040] According to another specific embodiment of the present application, as shown in Figure 3 The insulating film can effectively isolate the direct contact between the battery cell 3 and the cross beam 15, prevent short circuit caused by mechanical wear or accident, and ensure the safe operation of the CTP battery pack. The insulating film ensures the electrical insulation between the battery cell 3 and the cross beam 15, avoiding potential electrical damage to the battery cell 3 or the entire CTP battery pack 100 caused by the possible electrification of the cross beam 15. The insulating film can reduce the direct friction between the battery cell 3 and the cross beam 15, reduce the mechanical wear that may occur during long-term use, and prolong the service life of the battery cell and the cross beam.

[0041] The above technical solution can prevent short circuit caused by mechanical wear or accident, and ensure the safe operation of the CTP battery pack 100.

[0042] According to another specific embodiment of the present application, as shown in Figure 3 The buffer material 13 can absorb and disperse the energy transmitted to the battery cell 3 due to vibration and impact during vehicle operation, reduce the mechanical stress on the battery cell 3, and protect the battery cell 3 from damage. At the same time, the buffer material 13 can prevent the battery cell 3 from being damaged, and can play a protective role when the vehicle collides or the CTP battery pack 100 is subjected to external impact, preventing the battery cell 3 from directly contacting the hard first side plate 161 and / or second side plate 162, and reducing the risk of damage to the battery cell 3. Further, the buffer material 13 can fix the position of the battery cell 3, prevent the battery cell 3 from shifting due to vibration during transportation or use, and ensure the stability of the internal structure of the CTP battery pack 100. At the same time, the buffer material 13 can also help to provide uniform pressure distribution between the battery cell 3 and the first side plate 161 and / or the second side plate 162, avoiding deformation or damage of the battery cell 3 caused by excessive local pressure. In addition, the buffer material 13 can also play the role of elastic filling. In particular, the buffer material 13 is made of expanded polypropylene (EPP).

[0043] The above technical solution can play a shock-absorbing role on the battery cell 3 in the CTP battery pack 100, prevent the battery cell 3 from being damaged, and keep the position of the battery cell 3 from moving.

[0044] According to another specific embodiment of the present application, the cross beam 15, the first side plate 161 and the second side plate 162 are integrally formed. The integrally formed structure design can provide higher overall strength and rigidity of the CTP battery pack, because this design reduces the joint points, so that the CTP battery pack 100 can better maintain the shape and structural integrity when subjected to external forces. Integrally forming reduces the assembly steps of multiple components, reduces manufacturing complexity and cost, and improves production efficiency. Because there is no extra joint space between components, the integrally formed design can more effectively utilize the internal space of the battery pack, accommodate more battery cells or increase the compactness of the battery pack, thereby improving the energy density of the CTP battery pack 100. Integrally forming helps to improve the size and shape consistency of the product, reducing the performance differences of the product caused by assembly errors.

[0045] The above technical solution can improve the strength and rigidity of the CTP battery pack, simplify the production and manufacturing process, improve the energy density of the CTP battery pack 100, and ensure the consistency of the CTP battery pack 100.

[0046] According to another specific embodiment of the present application, as shown in Figure 1 The CTP battery pack 100 further comprises a busbar 5, and the battery cells 3 are electrically connected through the busbar 5. The material of the busbar 5 is aluminum or aluminum alloy. Aluminum and aluminum alloy have very high electrical conductivity, which can effectively reduce resistance and reduce the loss of electrical energy during transmission, thereby improving the overall efficiency of the battery pack. At the same time, aluminum and aluminum alloy have lower cost than other conductive materials (such as copper), which can reduce the manufacturing cost of the battery pack while ensuring performance.

[0047] The above technical solution can ensure the electrical conductivity between the battery cells 3, reduce resistance loss, and reduce the manufacturing cost of the CTP battery pack 100.

[0048] According to another specific embodiment of the present application, as shown in Figure 2 The CTP battery pack 100 further comprises a busbar 5, and the battery cells 3 are electrically connected through the busbar 5. The material of the busbar 5 is aluminum or aluminum alloy. Aluminum and aluminum alloy have very high electrical conductivity, which can effectively reduce resistance and reduce the loss of electrical energy during transmission, thereby improving the overall efficiency of the battery pack. At the same time, aluminum and aluminum alloy have lower cost than other conductive materials (such as copper), which can reduce the manufacturing cost of the battery pack while ensuring performance.

[0049] In some embodiments, the busbar 12 is a copper bar. The busbar 12 is thicker than the thickness of the busbar 5, and is fixedly connected to the first end plate 111 or the second end plate 112 through the busbar 12, so that the busbar 5 is fixedly connected to the first end plate 111 or the second end plate 112, and the busbar 5 is stably fixedly connected to the first end plate 111 or the second end plate 112, ensuring that the busbar 5 has a certain strength when resisting shocks and impacts. The thickness of the busbar 12 provides a stronger mechanical fixing point, so that the busbar 5 can be more stably fixed to the first end plate 111 or the second end plate 112, reducing the displacement that may occur under vibration or impact. The busbar 12 is thicker than the busbar 5, so it has higher mechanical strength and can better resist the influence of external forces, protecting the busbar 5 from damage. During vehicle operation, the battery pack 03 may be subjected to vibration and impact, and the design of the busbar 12 can improve the shock resistance and impact resistance of the entire CTP battery pack 100, ensuring the long-term stability of the CTP battery pack 100.

[0050] The above technical solution can improve the shock resistance and impact resistance of the CTP battery pack 100 and ensure the stability of the CTP battery pack 100.
