There are three types of commonly used rural solar street light batteries: lithium batteries, lead-acid batteries and colloidal batteries. Each has its own strengths and characteristics.
Among them, lithium batteries are becoming more and more popular in the solar industry due to their longer service life. So, what are the specific advantages of using lithium batteries for rural solar street lights?
1. With high storage energy density. Compared with other batteries, lithium batteries have a higher energy density, which has now reached 460-600Wh/kg, about 6-7 times that of lead-acid batteries.
This means that lithium batteries are lighter at the same charging capacity. It is calculated that the weight under the same volume is about 1/5-1/6 of lead-acid products.
2. Lithium battery is a controllable and non-polluting energy storage battery. In addition, lead-acid battery solar street lights are often criticized for "new half year, old half year, maintenance and then maintenance half year", short life.
The service life of lithium battery solar street light is generally more than 10 years, and the service life of LED light source is generally up to 10 years (about 50,000 hours), which can perfectly match the system.
3. Li-ion battery solar street light can also calculate the remaining battery capacity, day and night time, weather conditions and other factors according to the user's needs intelligently and optimally to reasonably allocate the level of electricity consumption and realize the functions of light control, time control, storage memory, etc. , thus ensuring continuous cloudy and rainy day lighting for ten days.
4. High and low temperature adaptability. Lithium battery can be used at -45℃-60℃, after process treatment can be used at -45℃.
5. Lithium battery is safer. Lithium battery is a dry battery, more stable and safer than lead-acid batteries.
