Advantages of solar street lamp energy storage lithium iron phosphate batteries
Solar street light power generation system has high cost, low conversion efficiency, and strong variability with the environment, so it has high requirements for energy storage. The service life of solar photovoltaic power generation system is generally 20 years, and the energy storage lithium iron phosphate battery link required with it has the characteristics of long service life, stable performance, high energy efficiency, and strong adaptability to the environment.
1. Light weight and small size
The total weight and volume of the energy storage lithium iron phosphate battery are 1/3 of the lead-acid battery of the same specification, and it can be easily carried by the elderly, women, or children.
2. Low temperature resistance
Ordinary lead-acid batteries have less than 50% power when the temperature is below 0°C. Li-ion batteries can still release more than 90% of the power at -20°C, and can still release more than 80% of the power at -40°C.
Three, long life
Energy storage lithium iron phosphate batteries have been charged and discharged more than 300 -2000 times in practical applications, and their capacity is not less than 80% of the original capacity, while lead-acid batteries have only 60% remaining capacity after being charged and discharged 200 times.
