The efficient energy-saving advantages of solar street lamps have been widely promoted and applied. There are three major types of solar cells in solar street lamps, namely lithium iron phosphate batteries, lead-acid batteries and gel batteries. Among them, lithium iron phosphate batteries rely on them. It is getting more and more popular in the solar industry than the other two. So, what are the advantages of lithium batteries?
1. Intelligent optimization calculation, reasonable distribution of electricity levels
The solar street lamp lithium battery can also intelligently optimize the calculation of the remaining capacity of the battery, the length of day and night, the weather conditions and other factors according to the user's needs, and rationally allocate the power level, and realize the functions of light control, time control and storage memory to ensure the continuous rainy day. light.
2. Lithium battery is a dry battery
A controllable, non-polluting energy storage battery is more stable and safer than a lead acid battery.
3 . Lithium battery has a long life
Unlike lead-acid batteries, which have to be replaced in two or three years, the service life of lithium batteries is generally more than 10 years. In solar street light systems, the service life of LED light sources is generally about 10 years (about 5,000 hours). That is, it can be perfectly matched with the system, eliminating the cumbersome process of frequently replacing the battery.
