[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source, integrating advanced technologies in vehicle power control and drive systems to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles. Currently, most new energy vehicles are pure electric. A pure electric vehicle is a vehicle that uses a single battery as its energy storage power source. It utilizes the battery as an energy storage power source to provide electrical energy to the electric motor, driving the motor and thus propelling the vehicle. Therefore, a charging socket is essential for the charging process of pure electric vehicles, requiring regular charging.
