A wireless communication technology-based charging pile using off-grid photovoltaic power generation, comprising a housing (2), a power generation device (1) disposed on top of the housing, a display device (3) disposed on the housing, a control device (5), a card reader (6) and two charging devices (4). The charging device comprises a light focusing mechanism, a photovoltaic mechanism, a vertically arranged connecting rod (1-3), and a cylinder (1-6) disposed on top of the housing. The charging pile communicates in real time with a smart communication terminal by means of a wireless communication module (8) to ensure that a user can monitor the charging state in real time. By focusing sunlight on the photovoltaic mechanism by means of the light focusing mechanism, the photovoltaic mechanism generates power. By using the connecting rod to control the height of the light focusing mechanism and a driving motor (1-9) to control the angle of a convex lens (1-8), efficiency of power generation and service life of photovoltaic assemblies are improved, ensuring reliability and utility of the charging pile.
