Automotive high voltage cables for efficient power transmission

China [CN]

Overview: High-voltage cables are also called high-voltage wires. Compared with high-voltage wiring harnesses, wiring harnesses are combined with high-voltage connector products and can be directly applied to vehicle-mounted equipment. Among them, high-voltage wiring harnesses are the carrier of electric vehicle power output and are key components that affect the performance and safety of the entire vehicle. In order to avoid accidental touch and short circuit, the wiring harnesses of new energy vehicles should be insulated, and the inner core of the wiring harness conductors is mostly made of copper wire, because copper has low resistance and strong plasticity.

The high-voltage wiring harness of the car is a bridge for communication between the control components, control units, and execution units of the car. It is the carrier of automobile energy and various signal transmissions, and it is the nervous system of the car.

The voltage of the high-voltage wiring harness of new energy vehicles is high, and the risk of injury to the human body when accidentally touched is also high. In order to prevent voltage leakage, the high-voltage wiring harness needs to be designed with greater insulation. The interior of the vehicle is generally affixed with stickers with various symbols, and bright orange insulating materials are used to warn of danger.

The wiring harness needs to carry higher power, which means that the current carried is also greater. Therefore, the wire diameter of the high-voltage wiring harness is generally designed as a copper cable, and the outer diameter is thick and thick.

The current of high-voltage system components is usually 250A, and some high-power motors have higher currents. Generally, the greater the current, the more heat is generated, which also means that the high-voltage wiring harness has requirements for temperature resistance. The conventional high-voltage wiring harness has a temperature resistance of -40℃~150℃.

The interior of the car is affected by electromagnetic interference from high voltage and high current. Electrical components will generate a lot of electromagnetic interference. The entire high-voltage system of the car needs to be covered with a shielding layer. The high-voltage wiring harness is usually designed as a shielding structure, and then connected to the battery motor controller housing through a crimping structure such as a plug-in, and then connected to the body ground.
