The advantages of lithium battery in solar street light are obvious:
1. Lithium battery has high energy density, which can store more energy, thus prolonging the working time of the solar street light.
2. Lithium battery has long life, which can withstand many charging and discharging cycles, and reduce the frequency and cost of replacing the batteries.
3. Lithium battery is relatively lightweight, which reduces the overall weight of the solar street light, and facilitates installation and maintenance.
4. Lithium battery has excellent environmental performance, and does not contain lead and harmful substances, which meets the concept of green environmental protection of solar street light. Lithium batteries have excellent environmental performance, do not contain lead and other harmful substances, in line with the green concept of solar street lights.
The life of lithium batteries for solar street lights is generally between 5-15 years, depending on a number of factors, including the use of the environment, maintenance, as well as the quality and type of batteries.
Solar street lights in the selection of batteries, we would like to choose lithium batteries, these lithium batteries basically have the nature of dry batteries, they are a high controllability and no pollution of the energy storage battery, compared to lead-acid batteries, this lithium battery will be more secure, but also more stable.
In solar lights, lithium batteries and lithium iron phosphate batteries can be used, but they are still different in performance and characteristics. Lithium batteries generally refer to lithium-ion batteries, which have the advantages of high energy density, stability, long service life, etc. It is one of the more popular battery types in the current battery market.
1. Solar energy collection and conversion
Lithium battery solar street lights first need to collect and convert solar energy through solar modules. The solar module consists of multiple photovoltaic cell chips, which convert solar energy into direct current energy through light radiation. Photovoltaic cell chips are usually made of silicon material, through the photovoltaic effect of electricity will be converted into electrical energy, in the strong light can achieve high energy conversion efficiency
2. Lithium battery energy storage
Need to store electricity to meet the night street lamp solar energy components will be converted to DC energy, lighting needs. At this time, lithium battery debut. Lithium battery is a high energy density, long life battery can be charged and discharged many times, very suitable for solar street lamp energy storage system. Solar power is charged into the lithium battery through the charger and stored as potential power.
3. Controller manages and deploys the electric energy
The potential power stored in the lithium battery needs to be managed and deployed by the controller to ensure that the power is effectively and stably supplied to the street light. The controller is one of the key components of the solar street light, with a variety of functions. First of all, the controller can monitor the voltage and current of the solar module, and determine whether the light intensity is sufficient to support the normal work of the street lamp; secondly, the controller can also detect the brightness of the street lamp and the ambient light conditions, so as to intelligently adjust the brightness of the street lamp; finally, the controller can also achieve the charging and discharging management of lithium batteries, as well as the protection of the power and optimization of the control.
4. Street Lighting
The controller effectively outputs electricity to the solar street light to make it work normally and realize the splendid lighting effect. LED light source is usually used in street lights, which is characterized by high efficiency, low energy consumption and long life. Once the controller detects that the solar energy collected by the solar module is enough to support the normal operation of the street light, the LED light source will be lit and emit bright light.
5、Light control and time control
In order to improve the energy utilization and service life of the solar street light, light control and time control functions are also applied to its work. The light control function can intelligently adjust the brightness of the street light according to the real-time light situation, thus avoiding wasting too much power during the day or insufficient lighting at night: the time control function can realize the timed control of the street light's on and off time, so as to ensure that the street light will be activated only when it is needed, saving energy.
Choosing the right solar street light lithium battery pack needs to consider the following core factors: the power of the solar street light, the usage time, the weather and light condition of the location and the night lighting demand. Usually, it is more appropriate to configure 15Ah to 20Ah lithium batteries for 30W solar street lights, but if the local cloudy and rainy days are more frequent or the demand for nighttime illumination is higher, a lithium battery with a larger capacity should be selected12.
First of all, the higher the power of the solar street light, the higher the battery demand. For example, a 30W solar street light needs to be equipped with lithium batteries of the corresponding capacity to meet the nighttime lighting demand.1 Secondly, the usage time of the street light is also an important factor. If the lighting demand is high at night, the battery capacity naturally cannot be small. For example, if a 30W solar street light needs to be illuminated for 8 hours a day, the required lithium battery capacity is 18Ah to ensure that it can still work properly under continuous cloudy and rainy days.1 In addition, the weather and light conditions of the location are also very critical. In places with strong light, the battery can be smaller because it charges more quickly, while in places with weak light, a larger capacity battery is needed to store enough energy.2 Finally, the appropriate battery capacity is selected in conjunction with nighttime lighting needs. If there is a high demand for nighttime lighting, the battery should be correspondingly larger.
