Description

A dedicated high-voltage wire assembly that connects the power battery, controller, and motor (some models include a DC-DC converter). Unlike the low-voltage wire harness you asked about before, it is specifically designed to carry the high-voltage DC power output from the battery (common voltages: 48V/60V/72V/96V; high-power models can reach 120V+).

The core functions are divided into 3 categories:

Main circuit power transmission: The high-voltage DC power from the battery is transmitted to the controller, and then the controller outputs it to the drive motor to provide power for the vehicle to move.
Safety protection and monitoring: Some high-voltage wire harness integrate temperature sensors and fuses/fuse holders to monitor the line temperature in real time and prevent safety hazards caused by overcurrent or overheating.
Electromagnetic compatibility and reliability protection: Through a special shielding layer and insulating materials, electromagnetic interference caused by high current transmission is reduced. At the same time, it is resistant to high temperature and bending, and is suitable for harsh working conditions during riding.

Application

High-power electric motorcycles / High-speed electric motorcycles

Connection sequence: Power battery pack → High-voltage main harness (with fuse + temperature sensor) → Controller → Drive motor; A branch line also connects to a DC-DC converter (to power the low-voltage system).

Features: Thicker wire diameter, equipped with safety monitoring components, higher insulation and protection levels, suitable for high current transmission requirements.

Lithium-ion battery-powered two-wheeled vehicles (BMS integrated models)

Connection sequence: Battery pack (built-in BMS) → High-voltage output harness → Controller; The BMS simultaneously transmits high-voltage interlock/fault signals to the controller via the low-voltage harness.

Features: The high-voltage main circuit is linked with the low-voltage signal circuit. When the BMS detects an abnormality, it can cut off the high-voltage output through the control circuit.
