Design and development of high voltage cables for electric vehicles

The continuous rise of international crude oil prices, the whole society's more concern about environmental degradation and global warming, coupled with the tax incentives and policy support of governments, have promoted the continued growth of the market share of new energy, especially electric vehicles. Develop globally. Electric vehicles mainly include three categories, namely pure electric vehicles, hybrid vehicles and fuel cell vehicles. Pure electric vehicles and fuel cell vehicles are powered entirely by electric motors, while hybrid vehicles combine an internal combustion engine and an electric motor, supported by the electric motor during acceleration and low speed situations when the internal combustion engine is not efficient. What they all have in common is the use of drive voltages up to 600V or higher. In terms of wiring, they all have the same basic requirement, which is to safely transmit large currents and voltages under an EMI (electromagnetic interference) protection system. As a high-voltage cable, it is used to connect high-voltage batteries, inverters, air-conditioning compressors, three-phase generators and motors to realize the transmission of power and electric energy. The fundamentals of electric vehicles seem simple. But digging deeper, system manufacturers are facing a series of challenges to overcome. For electric vehicle high-voltage cables, new technical requirements are put forward for items such as flexibility, shielding, safety, and size, because these will affect the wiring of high-current and high-voltage components. Facing the different technical points of each possible power system, different special requirements are also put forward for the required components. It should be noted that the high-voltage system of electric vehicles is not a typical high-voltage system, and related terms such as "high voltage" and "high current" must be limited to the scope of the automotive field, as opposed to the low-voltage system used in traditional vehicles. In other fields, reference systems use entirely different standards. For example, the definition of high voltage in the electric power field starts from several thousand volts.
