Application and Challenges of Low Voltage Automotive Wires in Electric Vehicles

The rapid development of new energy vehicles, especially electric vehicles, has brought new challenges and opportunities to automotive wiring harnesses. The function of low-voltage automotive wiring harness in electric vehicles is similar to that of traditional vehicles, mainly connecting electrical components of new energy vehicles to achieve control of electronic and electrical components such as sensors/control units.

The wiring harness in electric vehicles is mainly divided into high-voltage wiring harness and low-voltage wiring harness. The high-voltage wiring harness has a voltage of 300V or above and is mainly used for the transmission of driving power for new energy vehicles; The voltage of the low-voltage wiring harness is below 60V, while the general voltage for vehicles is 12V, mainly used for transmitting signals throughout the vehicle. These wiring harnesses need to meet EMC standards to ensure their safety and reliability.

However, the wiring harness layout of electric vehicles faces some challenges. With the rapid development of new energy vehicles and the continuous growth of market ownership, users' requirements for the safety, reliability, and environmental protection of electric vehicles are constantly increasing. The number of new energy electrical components in cars has significantly increased, and new types of lines such as high-speed video data transmission have emerged. In addition, the design of the wiring harness for the entire vehicle needs to consider whether each component meets EMC standards, and the connection between each other must ensure "0" faults and be strong enough to ensure stable power supply and operation of the internal and external devices of the electric vehicle.

Overall, the application of low-voltage automotive wiring harnesses in electric vehicles faces many challenges, including how to meet higher safety and reliability requirements, how to respond to new electrical components and data transmission needs, and how to adapt to more complex vehicle environments. This requires us to fully consider these factors in the selection, design, and use process to ensure the safety and reliability of the wiring harness.
