Understanding the Classification of Wiring Harnesses in New Energy Vehicles

Apr 11, 2024

In the ever-evolving landscape of automotive technology, the advent of new energy vehicles has brought about a paradigm shift in the way we perceive and design vehicle wiring harnesses. Understanding the intricacies of these wiring harnesses and their classification is crucial for advancing the development and adoption of electric and hybrid vehicles. Let's delve into the various classifications of wiring harnesses in new energy vehicles:


1.Power Harnesses: Power harnesses form the backbone of electric and hybrid vehicles, facilitating the transmission of high-voltage electricity between the vehicle's battery, electric motors, and control systems. These harnesses are engineered to handle high currents and are comprised of high-quality wires, insulation materials, and connectors to ensure efficient power delivery and safety.

2.Control Harnesses: Control harnesses are responsible for interconnecting the myriad of control units, sensors, and actuators within the vehicle's electric and electronic systems. They transmit control signals and data, enabling real-time monitoring and management of various vehicle functions such as propulsion, braking, and safety systems. Control harnesses utilize low-voltage wires and specialized connectors to ensure precise signal transmission and system integration.

3.Signal Harnesses: Signal harnesses are dedicated to transmitting audio, video, communication, and networking signals within the vehicle. These harnesses facilitate the operation of infotainment systems, communication devices, and telematics features, enhancing the overall driving experience. Signal harnesses include audio cables, video cables, Ethernet cables, and other communication interfaces tailored to meet the demands of modern vehicle connectivity.

4.Charging Harnesses: Charging harnesses enable the connection between the vehicle's charging port and the external charging infrastructure. These harnesses handle both power and data transfer, allowing for safe and efficient charging of electric vehicles from various charging stations. Charging harnesses are designed with robust materials and connectors capable of withstanding high currents and harsh environmental conditions.

5.Auxiliary Harnesses: Auxiliary harnesses encompass a wide range of wiring systems that support auxiliary functions and accessories in new energy vehicles. These harnesses connect components such as air conditioning systems, lighting systems, safety features, and other ancillary devices to the vehicle's electrical system. Auxiliary harnesses are customized to accommodate the specific requirements of each auxiliary component, ensuring seamless integration and operation.


Understanding the diverse classifications of wiring harnesses in new energy vehicles underscores the complexity and importance of these critical components in modern automotive design. As the automotive industry continues to embrace electrification and sustainable mobility solutions, advancements in wiring harness technology will play a pivotal role in shaping the future of transportation.


Through continuous innovation and collaboration, automotive manufacturers, suppliers, and technology partners are poised to drive forward the development of high-performance wiring harnesses that meet the evolving demands of new energy vehicles, paving the way for a cleaner, greener, and more connected automotive future.
