Under the pressure of energy and environmental protection, new energy vehicles will undoubtedly become the development direction of future cars. New energy vehicles include four types: hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, other new energy (such as supercapacitors, flywheels and other efficient energy storage) vehicles. With the active policy on pure electric vehicles, in order to solve the pain points of the high-voltage wiring harness EMC poor electromagnetic compatibility and other industries, BEISIT took the lead in developing products that meet the use of pure electric vehicles, becoming the first manufacturer to launch spring shielding products in China, and triggered the domestic peers to follow suit. At present, it has carried out good exchanges and cooperation with well-known domestic OEMs and three power enterprises. At present, the products are mainly used in new energy vehicles motor, electric control, battery and other parts.

Narrow new energy vehicles can refer to the provisions of the national "New Energy Vehicle Production Enterprises And Product Access Management Rules" : New energy vehicles refer to the use of unconventional vehicle fuel as a power source, comprehensive vehicle power control and drive advanced technology, formed with new technology, new structure, advanced technical principles of the car.
