[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four major types: hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as supercapacitors, flywheels and other high-efficiency energy storage devices). Existing new energy electric vehicles will be charged through charging piles after being used for a period of time, thereby ensuring that the vehicle has sufficient energy.

Some charging piles with winding structures mostly require manual control and occupy a large space, which cannot meet the use needs. Therefore, a charging pile for new energy vehicles is designed.
