Tell me about the lithium batteries for solar street lamps that our factory has made in the past two years
1. Ternary 3.7V, lithium iron phosphate 3.2V, three-string ternary 11.1V, four-string iron-lithium 12.8V, these are the most commonly used batteries for solar street lights, flood lights, and garden lights. There are also many 3.2V square batteries that are disassembled, mainly because they are cheap, but they are easy to bulge.
2. Ternary 11.1V, iron lithium 12.8V, we usually call it 12V. Relatively speaking, lithium iron is safer and more expensive. It is basically used in solar street lights and monitoring. The split is a solar panel on the top of the lamp that we usually see, the battery case is under the panel, and the lamp holder or camera is next to it. The battery and controller are installed in the shell, and the aluminum shell or plastic shell is used according to the customer's requirements, and two wires are directly connected, one is connected to the solar panel, and the other is connected to the lamp holder. The other is an intelligent integrated street light. The street light poles we usually see only have lamp caps on them, and solar panels and battery cases cannot be seen. This is an integrated light, the solar panel is directly connected to the sky facing the lamp head, and the battery is also installed inside the lamp head. The picture is the battery we made, the one with the shell is for the split unit, and the one with the blue PVC shrink wrap is for the integrated lamp.
Why do solar street lights use lithium batteries?
The advantages of solar street lamps and high efficiency and energy saving make it widely popularized and applied. There are three important components of solar street lamp solar cells, which are lithium iron phosphate batteries, lead-acid batteries and colloidal batteries. Among them, lithium iron phosphate batteries are due to their The service life is higher than the other two, and it is beginning to be more and more favored by the solar industry. So what are the advantages of lithium-ion batteries?
1. Lithium-ion battery is a dry battery:
Controllable, non-polluting energy storage batteries, which are more stable and safer than lead-acid batteries.
2. Intelligent optimization calculation, reasonable distribution of power consumption: solar street light lithium-ion battery can also be intelligently optimized calculation according to the user's demand for the remaining capacity of the battery, the length of day and night, weather and other factors, reasonably distribute the power level, and realize light control , time control and memory storage function, make sure the lights keep on in rainy days.
3. Long life of Li-ion battery:
Unlike lead-acid batteries, which are replaced within two to three years, lithium-ion batteries generally have a service life of more than 10 years. In a solar street lighting system, the service life of the LED light source is generally as long as 10 years (about 50,000 hours). Lithium-ion batteries can be used to perfectly match the system, eliminating the tedious process of frequent battery replacement.
