New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels or new on-board power devices), integrate advanced technology in vehicle power control and driving, and form advanced technical principles, new technologies, and new structures. New energy vehicles include four major types: hybrid electric vehicles (HEVs), pure electric vehicles (BEVs, including solar powered vehicles), fuel cell electric vehicles (FCEVs), and other new energy vehicles (such as supercapacitors, flywheels, and other high-efficiency energy storage devices). Non conventional automotive fuels refer to fuels other than gasoline and diesel. In 2012, Pingshan District of Shenzhen was approved as a national level new energy vehicle industry base. Relying on this "national brand" golden signboard, nearly 300 new energy enterprises gathered in Pingshan, forming a new energy industry chain and cluster with high technological content, strong innovation ability, and outstanding demonstration effects, becoming one of the three leading industries supporting "Innovation Pingshan".
