Power transmission: It includes cables used for transmitting high-voltage power, which connect battery packs, motors, electronic control units and other power components of electric vehicles. These cables must be capable of withstanding high current loads while maintaining safe and efficient power transmission.
Data transmission: It includes cables used for transmitting data and communication signals, which are used to monitor and control information such as battery status, motor performance, and charging status, and are crucial for the normal operation and management of vehicles.
Sensor connection: Usually, various sensors are connected, such as temperature sensors, speed sensors, position sensors, etc., to monitor the vehicle's status and provide feedback to the control system.
Electronic Control Unit (ECU) connection: It connects various ECUs to manage and control various systems of the vehicle, including the battery management system (BMS), motor control unit (ECU), braking system, air conditioning system, etc.
High-temperature resistance and corrosion resistance: Considering that new energy vehicles may operate under high-temperature or humid conditions, the wiring harness must possess the characteristics of high-temperature resistance and corrosion resistance to ensure long-term stable performance.
Modular design: To simplify manufacturing and maintenance, the wiring harnesses of new energy vehicles typically adopt a modular design, allowing each subsystem's wiring harness to be manufactured and installed independently.
