5 improvement and application of new technology and process methods

1) The method of mixed welding of copper and aluminum lines is shown in Figure 6. This hybrid welding scheme is suitable for long, large square meters of battery line solutions.

This solution can be considered according to the layout direction and space of the 3D layout stage. For example, in a space, there is a generous space in a space to accommodate the line diameter of the aluminum wire. The space of the end -hole terminal connecting the electrical side is limited, and the copper wire solution can be adopted. In this way, the hybrid use of the two wires can perfectly solve the problem of uneven space. It is also considered for the lightweight direction of the wire beam and reducing the cost direction.

2) In addition, a soft -state aluminum duct currently can effectively solve the problem of space occupation caused by the increase in aluminum wire diameter. The aluminum lines are shown in Figure 7.

The aluminum cable adopts solid aluminum flat wire structure, which effectively reduces the overall space occupation of the wires, more fit the body, and at the same time, the special conductor structure reduces the processing cost of the wire and further reduces the wire cost. The aluminum cable is likely to be the development direction of the low -voltage cable beam in the future.

At present, automotive electrification and high voltage of automobiles have become the development trend of the automotive industry. High -voltage line beams are mainly copper -guided lines. The existing high -voltage line beam has the characteristics of long wire length, large wire square number, and high proportion of copper. The proportion of the quality of the vehicle is getting greater, and the mileage anxiety of electric vehicles today has become a major obstacle to the promotion of electric vehicles. Decreasing through the vehicle, reducing mileage anxiety is a problem that electric vehicles must solve.

The application of high -voltage aluminum wires provides a good solution for the reduction of the entire vehicle beam and reducing costs. At present, the industry is exploring the application of high -voltage aluminum wires. Exploring the application, the future of aluminum high -voltage line beam must be the application direction of high -voltage line beams.

6 summons

In summary, the aluminum wires are used as an excellent replacement of copper wires in the automotive industry and have undergone multiple verification solutions, which will bring huge motivation to the development of the automotive industry from the perspective of cost and vehicle weight loss. In the future, electric vehicles will develop rapidly. High -voltage line beams are generally applied to new energy vehicles. The application of aluminum high -voltage line beams will definitely bring new ideas and development directions to the development of new energy vehicle line beams.
