New energy vehicle's high voltage harness in which position

The high-voltage wiring harness of a new energy vehicle is between the controller and the motor, the battery high-voltage line is generally the high-voltage line connecting the controller and the battery, and the charging high-voltage line is generally the high-voltage line connecting the charger and the battery. The whole vehicle wiring harness as the vehicle signal transmission, vehicle power supply, vehicle function realization of the main connection and transmission system, in the design process at the same time also faces the design scheme, layout towards, EMC protection and other design aspects of the test.

Car manufacturers have launched their own new energy vehicle products, including pure electric vehicles, hybrid vehicles. And then with the gradual improvement of technology, has tended to use electricity to replace the traditional fuel as the power source of the car. For the design and research of new energy vehicles, there are a variety of design problems and the birth of new design concepts, the vehicle wiring harness as the vehicle signal transmission, vehicle power supply, vehicle function to achieve the main connection and transmission system, in the design process at the same time also faced with the design scheme, layout towards the design of the EMC protection and other aspects of the test.

In the new energy vehicles (pure electric for example) high voltage wiring harness can be divided into five major parts

1, the power battery high voltage cable: that is, connecting the power battery to the high-voltage box between the wiring harness.

2, motor controller cable: that is, connecting the high-voltage box to the motor controller between the harness.

3, fast charging harness: the harness connecting the fast charging port to the high-voltage box.

4, slow charging harness: that is, the harness connecting the slow charging port to the on-board charger.

5, high-voltage accessory harness (high-voltage harness assembly): that connects the high-voltage box to the DC/DC, on-board charger, air-conditioning compressor, air-conditioning PTC harness.
