Problems solved by technology

However, the structure of the microcontroller is relatively complicated, the circuit occupies a large area, and the cost is high. It is generally used in large-scale solar power generation systems. The solar panel power of the portable power supply system is small, which will increase the proportion of self-loss, which will reduce the efficiency of the system itself, and will greatly increase the cost. The miniaturized portable power supply system is mainly used in Southeast Asia, Africa and other regions, and is sensitive to product prices. , is not conducive to the promotion of products

Description

technical field [0001] The invention relates to the field of solar power supply, in particular to a solar charging control circuit and method. Background technique [0002] With the deterioration of the earth's ecological environment, since the beginning of the new century, human beings have encountered an unprecedented survival crisis. Human beings have only one earth, and its ecological system cannot be recreated. Saving energy and protecting the environment have become the necessary conditions for the sustainable development of human beings. People's attention is turning to the utilization and development of renewable energy. Among them, solar power has become a research hotspot in recent years. Solar energy is a low-density, intermittent, and spatially changing energy source, which puts forward higher requirements for the collection and utilization of solar energy. A photovoltaic charging system generally includes solar panels, solar controllers, and batteries. The curr...
