Which type of battery is the best for solar street light lithium battery?

With the continuous advancement of science and technology, the application range of batteries has been extensive. In addition to the common use of lead-acid batteries and gel batteries, lithium batteries has been a hit in for today’s solar street light lithium battery. As it is not only energy-saving and environmentally friendly, but also do not incur electricity bills.

What is Solar street light?

Solar street lights are powered by crystalline silicon solar cells, lithium battery packs store electrical energy, ultra-bright LED lamps are used as light sources, and are controlled by an intelligent charge and discharge controller to replace traditional public power lighting street lights. Solar street light with battery and panels. Do not need to lay cables, do not require AC power supply, and do not incur electricity bills; use DC power supply and control; have the advantages of good stability, long service life, convenient installation and maintenance, high safety performance, energy saving, environmental protection, economy and practicality. 

Which type of battery is the best for solar street light battery?

In the past, many solar street lights used lead-acid batteries, but now they switch to lithium batteries. Compared with lead-acid batteries, the advantages of lithium batteries are significant.

1-structure of solar street lamp

Small size and portable

Lithium battery has small volume, light weight and easy transportation. In the solar street light with the same power, the weight and volume of lithium battery is about one-third of that of lead-acid battery. In this way, transportation is easy and the transportation cost is naturally reduced.

2-structure of solar street light

High energy density and longer service life.

Energy density refers to the energy stored in a certain space or mass unit. The higher the energy density of the battery, the more electricity stored per unit weight or unit volume. There are many factors affecting the service life of lithium battery, and energy density is one of the most important internal factors.

3-lithium battery

Pollution-free

Lead-acid batteries are polluted by heavy metal lead. There are a large amount of lead and acid in lead-acid batteries. After being discarded, if they are not handled well, they will pollute the environment. While lithium batteries are environmentally friendly, free of any pollutants, and no pollution during production and use.

More intelligent

When using lithium batteries, solar street lights can intelligently optimize the calculation of battery capacity, service time, weather conditions and other factors according to user needs. Besides, It can reasonably allocate power levels, and realize light control and time control. And storage memory and other functions to ensure that the lights can be turned on continuously for 10 days even in rainy weather.

Excellent temperature adaptability

Lithium battery has strong temperature adaptability. It can work normally in the environment of – 20-60 ℃, even in the freezing environment of – 45.

5-installation of battery

Easy to install and maintain

Lithium battery solar street lamp is easy to install. When installed with traditional batteries, a battery pit shall be reserved, and the batteries shall be put in and sealed with buried boxes. The installation of lithium battery solar street lamp is much more convenient. The lithium battery can be directly installed on the bracket, which adopts hanging type or built-in type. More importantly, they are easy to maintain. They only need to remove the battery from the pole or battery panel during maintenance, while traditional solar street lamps need to dig out the buried battery, which is much more troublesome than the lithium battery street lamp. In addition, the energy storage lithium battery is installed near the lamp pole to shorten the power supply distance, reduce the power loss of the line and ensure the effective power supply of the LED lamp power supply! At the same time, the battery is placed at the height of the lamp pole to prevent the battery from being buried under the lamp pole, which is easy to be stolen.

Conclusion

In conclusion, Lithium batteries have outstanding characteristics such as high efficiency, lightness and long life. The lithium battery energy storage solar system came into being, which solved the short battery life of traditional solar street light systems and the solar street light lithium battery weight can only be buried underground.
