Abstract

At present, the solar energy used in the Internet of things for agriculture has the characteristics of finiteness, randomness and discontinuity. How to store energy more efficiently in the time of energy storage has become an important problem. In this paper, the polarization of lithium iron phosphate battery is studied, and its constant current constant voltage charging mode is analyzed. A dual power management system is designed by controlling the time of constant voltage charging stage. Compared with the existing scheme, the charging scheme of the system reduces the influence from the battery polarization and improves the charging efficiency.
