Automobile High Voltage Wiring Harness (High Voltage Distribution Box - Motor) Can Be Fixed Customized

Automobile high voltage wiring harness (high voltage distribution box - motor) can be fixed customized

1. Product description

  Automobile high voltage wiring harness (high voltage distribution box - motor) is mainly used to connect the high voltage distribution box and motor. The high voltage automobile wiring harness is composed of a number of high voltage cables, and the two ends are connected to the distribution box and the motor respectively. The cable adopts special layer upon layer insulation structure, which is composed of copper core, insulation layer and sheath.The high voltage connectors at both ends of the automotive high voltage wiring harness are designed with professional quick locking to reliably connect the distribution box to the motor and ensure stable contact. At the same time with waterproof, dustproof and other functions.

  The automobile high voltage wiring harness adopts double layer shielding design to effectively isolate the interference of external electromagnetic field and ensure the stable transmission of high voltage signals. The design of the whole high voltage harness conforms to automotive electrical standards, with overload protection, short circuit protection and other safety measures, reliable protection of motor and vehicle users safety.

4. Application area

I: BEV application: In BEV, the high voltage wiring harness is responsible for connecting the HV distribution box to the drive motor to provide HV power to the motor. In this application scenario, the harness needs to withstand up to 600V operating voltage, so it must have adequate insulation and safety protection measures.

II: Hybrid vehicle application: On hybrid vehicles, in addition to connecting high-voltage distribution boxes and drive motors, high-voltage wiring harnesses may also be connected to high-voltage battery packs, DC/DC converters and other high-voltage components. The high voltage harness needs to take into account the power supply requirements of different high voltage components to ensure the reliable operation of the whole high voltage system.

III: Motor control application: The high voltage harness is not only responsible for driving the motor power supply, but also will transmit the motor control signal. These signals include key parameters such as motor speed, torque and temperature. The high voltage harness needs to have good anti-interference performance to ensure stable signal transmission.

5. Feature

I: High voltage transmission capacity: As a key connector of high voltage power supply system, automotive high voltage harness must have the ability to carry voltage up to 600V or more. The insulation materials and structural design of the cable have been rigorously tested to ensure reliable transmission of power under high voltage conditions.

II: Anti-interference performance: In addition to transmitting power, the high voltage harness will also transmit various detection and control signals of the motor. In order to avoid signal interference, the wire harness adopts double shielding layer design to effectively isolate electromagnetic interference. At the same time, the grounding of the harness is specially optimized to further improve anti-interference.

III: Temperature resistance: the automobile high voltage wire harness will experience a wide temperature condition from -40℃ to +125℃ during the operation of the automobile. To this end, the high voltage harness is made of temperator-resistant materials tested at both high and low temperatures, ensuring that excellent mechanical and insulating properties are maintained even under extreme temperature conditions.
