AutomobileHigh-voltage cable construction process from fine copper core to efficient insulation layer

China [CN]

Electric vehicles mainly include three categories, namely pure electric vehicles, hybrid vehicles and fuel cell vehicles. Pure electric vehicles and fuel cell vehicles are completely driven by an electric motor, while hybrid vehicles combine internal combustion engines with electric motors, which are supported by electric motors when the efficiency of the internal combustion engine is not high under acceleration and low-speed conditions. Their common feature is the use of driving voltages of up to 600V or higher. When it comes to wiring, they all have the same basic requirements, that is, safe transmission of high currents and voltages under EMI (electromagnetic interference) protection systems. As high-voltage cables are used to connect high-voltage batteries, inverters, air-conditioning compressors, three-phase generators and motors to achieve the transmission of power and electrical energy.

In-depth analysis shows that manufacturers of OMG cable manufacturers are facing a series of challenges to overcome. New technical requirements are put forward for electric vehicle high-voltage cables, such as flexibility, shielding, safety, and size, because these will affect the wiring of high-current and high-voltage components. And facing the different technical points of each possible power system, different special requirements are also put forward for the required components.

In summary, it should be noted that the high-voltage system of electric vehicles is not a typical high-voltage system. Relevant terms such as "high voltage" and "high current" must be limited to the automotive field, and are relative to the low-voltage system of conventional vehicles. In other fields, the reference system adopts completely different standards. For example, the definition of high voltage in the power field starts at several thousand volts.
