Application of lithium iron phosphate battery in photovoltaic power generation

High-performance energy storage batteries are critical to the development of the photovoltaic industry. Compared with lead-acid batteries, lithium iron phosphate batteries have the advantages of higher specific energy, higher energy storage efficiency, longer cycle life and lower cost of use. The use of this type of lithium battery as an energy storage device can increase the energy efficiency to about 90%, so it is very suitable for use as a new energy storage device. The lead-acid battery and the lithium iron phosphate battery were compared in terms of conventional performance and energy storage characteristics.

Among many renewable energy sources, solar energy has become the most promising form of energy with its characteristics of green, environmental protection, inexhaustible and inexhaustible, and has great market prospects. China has a very rich solar energy resources, and the development of the photovoltaic industry is of great significance to the improvement of electricity consumption in underdeveloped areas and remote areas of China. However, photovoltaic power generation has discontinuity and instability, and power generation performance changes with changes in the external environment. Therefore, high-performance power storage links are crucial to the development of the photovoltaic industry.

At present, most photovoltaic systems use lead-acid batteries as energy storage devices. Compared with lead-acid batteries, lithium iron phosphate batteries have the advantages of higher specific energy, higher energy storage efficiency, longer cycle life and lower cost of use. This paper compares lead-acid batteries and lithium iron phosphate batteries in terms of conventional performance and energy storage characteristics. Based on the analysis of the feasibility of using lithium iron phosphate battery as the energy storage device of photovoltaic system, the corresponding photovoltaic energy storage system was designed.
