Electric vehicles are cars that use batteries and electric motors without petroleum fuels and engines. Electric vehicles were first produced in 1873, but they were not put to practical use due to technical limitations such as heavy weight of batteries and charging time.

On the other hand, electric vehicles were produced in small quantities from the United States until the mid-1920s with advantages such as simple structure, durability, and easy operation. In recent years, regulations on exhaust emissions from vehicles have been rising due to environmental pollution (pollution) problems in the United States and Europe, and oil prices are soaring that electric vehicles are attracting attention as next-generation vehicles. In other words, electric vehicles using pollution-free electric energy are able to fundamentally solve environmental problems such as harmful exhaust gas and noise of internal combustion engines that occupy about 70% of air pollution factors, The resource life can be extended more than twice.

Accordingly, various technologies related to electric vehicles have been developed since 1990. In other words, automobile manufacturers are developing a variety of technologies to improve the relatively low battery capacity, long charge time, short travel distance, and slow running speed, which are technical problems of electric vehicles.

Recently, in order to overcome the long charging time which is one of the problems of electric vehicles, an interface part for a charging infrastructure for charging electric vehicles has been developed.
