Detailed Description

There are many types of high-voltage lines for new energy vehicles, and their applications in the car are mainly the following types of DC charging sockets: assembly wiring harness, AC charging socket assembly wiring harness, battery positive and negative wiring harness, on-board charger wiring harness, PDU wiring harness and so on.

There are three main forms of high voltage for new energy vehicles: continuous existence, existence during operation, and existence during charging.In general pure electric vehicles, the color of high-voltage cables is usually orange.Compared with low-voltage control lines, the diameter of high-voltage cables is much thicker, which is easy to identify.There are also high-voltage warning signs marked on the shell of the high-voltage controller or actuator.

Since high-voltage cables connect the battery, inverter and electric motor, high currents need to be transmitted.Depending on the power requirements of the system components, the current can reach 250A to 450A.Therefore, special materials need to be used in the design to withstand higher temperatures.

Cables and connectors also require space to route through, and in-vehicle routing often results in tight bend radii.High bending forces are difficult to overcome due to the inherent design of conventional cables.To solve this problem, high flexibility of high-voltage cables is crucial.Only a more flexible design, routing through the vehicle can be easily achieved.If the electric motor is located close to the moving parts of the vehicle and then causes the connected high voltage cables to vibrate continuously, it needs to be designed to withstand high cyclic bending to ensure good bending endurance.
