In order to make the device better capable of power supply, it is necessary to select a corresponding battery, and the lithium iron phosphate battery is favored for its excellent performance. In this study, the requirements of the lithium iron phosphate battery for optoelectronic complementary power supply system were analyzed at first, then the application of the battery in the supply system was further analyzed. Next, the structure and working principle of the battery were deeply studied, and a large number of experiments were designed to analyze the performance of the battery. It has been confirmed by a large number of experiments that the charging process of lithium iron phosphate battery is slow; the remaining capacity of lithium iron phosphate battery has a correlation with the voltage it carries. During the charging process, the internal resistance of the lithium iron phosphate battery will rapidly drop to a stable value, and the conversion of constant current charging to constant voltage charging will further reduce the internal resistance. Adjusting the battery temperature can adjust the internal capacity of the battery, that is, increasing the temperature can promote the expansion of the battery capacity to a certain extent, and lowering the temperature can impair the overall performance of the battery. In the battery AC (alternating current) impedance spectrum test, the impedance of the battery was affected by factors such as inductance, lithium ion diffusion, and internal polarization of the battery. Through the above research, the power consumption of lithium iron phosphate battery can be better understood to make better use of solar energy and provide people with stable green energy.
