Is the automotive wiring harness, especially the high-voltage wiring harness, the neural network system of the car? The high-voltage wiring harness is responsible for the connection of high-voltage electronic components in the car, which can provide stable power and signal transmission, and is an indispensable system-level component of the vehicle.

The high-voltage wire harness industry chain mainly includes upstream high-voltage cable and connector manufacturers, midstream high-voltage wire harness manufacturers, and downstream vehicle manufacturers. Pagoria is a provider of energy storage and electric vehicle connection solutions. We provide high-voltage wiring harnesses, which belong to the middle reaches of the industrial chain.

The high-voltage wire harness is formed by crimping high-voltage cables and contact terminals (connectors), and then bundling the outer layers with plastic-pressed insulators or metal shells.

The high-voltage wiring harness of new energy vehicles is mainly used to connect high-voltage equipment such as power batteries, drive motors, on-board chargers, DC/DC converters, high-voltage power distribution boxes, electric compressors, and PTCs.

From the specific application point of view, the high-voltage wiring harness can be used to connect the power battery and the high-voltage control box, the high-voltage control box and the motor controller, the fast charging port and the high-voltage control box, the slow charging port and the charger, etc. High-quality and efficient power transmission, shielding external signal interference.

The high-voltage wiring harness has a large current and a high electric field strength. It usually adopts a multi-core structure design. It is generally required to add a shielding layer such as a tinned copper wire braid, which is also to meet the EMC requirements for electromagnetic shielding. In order to ensure that the inner layer of the harness is not affected by mechanical system damage and chemical corrosion, it is often necessary to add an insulation layer to extend its service life.
