Introduction to welding and shaping process of high-voltage wire harness for new energy vehicles

China [CN]

The new energy vehicle wiring harness is responsible for transmitting signals and electrical energy, providing power supply for various electrical equipment, and ensuring the coordination of all parts of the vehicle is also one of its important responsibilities. The production and installation of high-voltage wiring harnesses directly affect the performance, efficiency and reliability of new energy vehicles.

New energy electric vehicles require a more powerful, fast and efficient power supply system. There are a large number of wiring harnesses arranged inside electric vehicles, which are used to transmit control signals and electrical energy, and supply power to electrical equipment. They are the important "central nervous system" of the vehicle. In order to ensure stable power supply to devices inside and outside the vehicle, the car wiring harness connection must be fault-free and strong enough.

Electric vehicles rely on strong electrical connections to efficiently distribute battery power, which involves wiring harness issues. Issues that need to be considered in wire harness layout include thermal management, contact resistance, connector size, mechanical stress load, etc., and the wire harness welding and shaping process can effectively solve the above problems.

The high-voltage wire harness welding and shaping process is to compact the loose multi-strand wire harness and weld it into the desired shape to facilitate connection with other components.

As contact resistance increases, current flow decreases and a large amount of heat is generated at the contact surface, which over time shortens the life of the harness. The high-voltage wire harness joints processed by the welding and shaping process will reduce the contact resistance and reduce the heat generated by the electrical system, thereby extending the service life.

The wire harness welding shaping process is an ideal solution for copper wire welding, ensuring reliable connection while increasing product life. High-voltage welding wire harness makes the connection safer and more reliable, and can effectively reduce problems caused by mechanical stress load.
