Lithium ion solar street lights, which do not emit CO2 and SO2, and do not generate noise, solid waste, and other pollution from conventional power generation, are currently one of the more important renewable energy technologies. With the continuous development of lithium battery solar street light power generation technology, the application of lithium battery advantages such as energy conservation, environmental protection, and safety has become a new favorite in the urban road lighting industry, with huge market potential. In different regions, such as cities or rural areas, the requirements for the lighting density of lithium-ion solar street lights vary, but the working principle of charging and discharging lithium-ion solar street lights, as well as the basic characteristics of lithium-ion batteries. According to different requirements, mainly considering practicality and economy, a lithium battery solar street light configuration with corresponding capacity suitable for local needs can be selected.
The working principle of lithium battery solar street lights: The solar panel receives solar radiation during the day, converts solar energy into electrical energy and outputs it. After integration with the solar controller, the electrical energy is stored in the lithium battery. When night falls and the working voltage of the solar panel is less than 4V, the solar controller automatically detects this voltage value and the battery supplies power to the LED street lights. At dawn, when the working voltage of the solar panel is greater than 4V, the solar controller stops supplying power to the LED lights and continues to charge the lithium battery.

The advantages of lithium battery solar street lights are mainly reflected in the following six aspects:

1、 It fully utilizes the continuous light resources of nature, has the advantages of energy conservation, environmental protection, and intelligent regulation, and does not require the consumption of traditional municipal electricity.

2、 The charging and discharging system adopts an integrated structure of lithium batteries and controllers, which is a controllable and pollution-free energy storage battery system. Lithium batteries generally have a longer service life and can perfectly match LED street light systems in practical applications.

3、 Lithium battery solar street lights can also intelligently optimize and calculate the remaining capacity of lithium batteries, day and night duration, weather conditions, and other factors according to user needs, allocate electricity levels reasonably, and achieve functions such as light sensing, time control, and storage memory, ensuring continuous illumination on cloudy and rainy days for three to five days.

4、 Lithium batteries belong to the nature of dry batteries, which are more secure, more stable, and safer than lead-acid batteries.

5、 Lightweight, with a weight of approximately 1/6-1/5 of that of lead-acid products in the same volume; Convenient construction and installation.

6、 Lithium batteries have strong adaptability to high and low temperatures, and can be used in environments ranging from -20 ℃ to 60 ℃. After process treatment, they can be used in environments ranging from -45 ℃.

7、 Long service life, no feeding phenomenon occurs during use. Also avoid battery loss.
