The battery voltage of new energy vehicles (mainly including hybrid and pure electric vehicles) can reach 600V, and the corresponding peak current of the wire can reach 300A. Compared with the 12V voltage of traditional fuel vehicles, new energy vehicles are more prone to overload, short circuit, spontaneous combustion, current leakage and other problems in high-voltage connection.

The high-voltage wiring harness of new energy vehicles is like the "blood vessels" of the car, running through various parts of the car, connecting all electronic components, and transmitting power and data. It belongs to safety components and has the characteristics of high voltage/high current, large wire diameter, and small bending radius. In addition, connectors need to be interwoven with wiring harnesses and connectors, and how to avoid connection failure is also a major challenge.
