Design of Solar Energy Automatic Tracking Lithium Battery Charging System Based on STM32 Single-Chip Microcomputer
With the rapid development of economic globalization and the world economy,people's demand for traditional energy sources such as coal and oil is increasing.However,these resources not only have limited storage,but are also prone to environmental pollution.At the same time,new energy represented by solar energy is gradually entering people's vision.In this context,in order to further improve the utilization rate of solar energy,the paper proposes a design scheme of a solar energy automatic tracking lithium battery charging system based on the STM32 Single-Chip Microcomputer.The light sensor collects light intensity from four directions to convert it into electrical signals.The electrical signals are converted into digital signals through AD conversion,and then the STM32 microcontroller performs data processing and analysis.The motor is driven to rotate according to the light intensity from four directions to keep the solar panel as perpendicular to the sunlight as possible,maximizing the absorption efficiency of solar energy.
