Vehicle-mounted high-voltage cable application characteristics

Where are the high-voltage wire harnesses needed for automobiles applied: In electric vehicles, the high-voltage electrical system is mainly responsible for starting, driving, charging and discharging, air conditioning power, etc. It mainly includes battery systems, powertrains, high-voltage electronic control systems, charging systems, high-voltage equipment, and wiring harness systems.

The high-voltage wires of electric vehicles are used to connect charging ports and batteries, battery interiors, batteries and engines and other components, as well as battery energy storage equipment, and are used as carriers for power transmission.

The biggest feature of automotive high-voltage wires is high voltage resistance. At present, the high-voltage wires used in the market are at the high-voltage resistance level of 600V AC/1000V DC. As the mileage increases and greater power output is required, higher voltage wires with higher voltage resistance levels will be required, and the voltage resistance level will reach and exceed the level of 1000V AC/1500V DC. High-voltage wire harnesses have high voltage and high current characteristics. As the main energy transmission channel, the high-voltage wire harnesses of new energy vehicles need to withstand large currents, of which the DC bus can reach more than 300A.
