Wiring Harness Assembly Video (14)

The application scenarios of new energy wiring harnesses mainly include on-board cables, charging guns/charging piles, on-board chargers, etc. New energy wiring harnesses are mainly used to provide high voltage and strong electricity for new energy vehicles, and account for a relatively high proportion in new energy vehicles. 

Safety parts have the characteristics of high voltage/high current and large diameter wires, which also makes the design of high-voltage wiring harnesses for new energy vehicles face many challenges. 

Basic characteristics of new energy wiring harness：

1. High voltage/high current

The battery voltage of new energy vehicles can reach 600V, and the corresponding wire withstand voltage level can reach 300A. The battery voltage of traditional fuel vehicles is generally 12V, and the corresponding wire withstand voltage level is less than 60V.

2. A large number of large-diameter wires

New energy vehicles require large-diameter wires in high-voltage batteries, inverters, transformers, low-voltage batteries, air-conditioning compressors, etc., and the number is very large.
