A. What is an electric vehicle wiring harness? An electric vehicle wiring harness is a system that combines electrical cables and wiring harnesses together. Electrical cables are an important part of the electrical transmission system, while a wiring harness combines multiple cables together to form a whole. An electric vehicle wiring harness packages all the components of wires, cables, sensors, motors, and control units needed for the electrical system together to form a complete power transmission system. An electric vehicle wiring harness typically consists of multiple electrical cables, each with one or more electrical connectors to allow the harness to be connected to other components when needed. The design of the wiring harness must take into account aspects such as circuit stability, water resistance, and vibration resistance. As a result, electric vehicle wiring harness design must take into account a variety of needs, such as strength, durability, and flexibility. The manufacturing of electric vehicle wiring harnesses requires a very high level of precision and technology, as each harness needs to be customized to meet the specific requirements of the electric vehicle. These requirements include the vehicle's size, power, features, control system and operating environment. The process of producing the harnesses requires numerous tests and calibrations to ensure that the harnesses will function properly and remain stable throughout the life of the EV. During the manufacturing process, specialized equipment and processes are required to perform steps such as wire stripping, insulation, braiding and assembly. Strict quality control and testing is also required to ensure the reliability and safety of the wiring harness. For the testing of electric vehicle wiring harnesses, it generally includes electrical testing, heat resistance testing, freezing resistance testing, vibration testing, oil resistance testing, environmental adaptability testing and many other aspects. The materials for electric vehicle wiring harnesses are usually made of fireproof materials, thermoplastic elastomers, polyvinyl chloride and other materials. The selection of these materials needs to take into account aspects such as durability, heat resistance and chemical resistance of the harness. Installation of wiring harnesses usually relies on specialized tools and techniques to ensure that the harnesses are properly installed into the structure of the electric vehicle and can be smoothly connected to other components. The primary function of electric vehicle wiring harnesses is to transmit power and signals. They are responsible for connecting the various electrical components of an electric vehicle together, including the motor, battery, charger, sensors, instrument panel, lights, stereo, and more. The role of the wiring harness is to transmit the required power and signals during the operation of the vehicle, so as to ensure that all the systems of the electric vehicle can work properly. The role of the electric vehicle wiring harness is to transmit the electrical signals from the various components of the vehicle to the control unit in order to realize the vehicle's control, monitoring and diagnostic functions. For example, the electric motor, battery, charger, braking system, steering system, airbags, doors, windows, lights and other components of the electric vehicle need to be connected to the vehicle's control unit through the wiring harness to realize the normal operation and control of the vehicle. Wiring harnesses are an integral and important part of the development and manufacturing process of electric vehicles. They provide stable and reliable power transmission and ensure that all parts of the EV can work together. With the development and popularization of electric vehicles, the importance of electric vehicle wiring harnesses is increasing, as they have a critical impact on the performance and reliability of electric vehicles
