With the increasing maturity of new energy technology, there is more and more demand for this in the global market. my country has also vigorously implemented green energy, energy saving and emission reduction, and then the application of solar street lamp systems is getting wider. The battery of the solar street lamp in the whole system serves as the core components in its system, and how do you choose? 1.

Solar street lamps Common classifications Currently, the solar stream battery in the market is important for lead-acid batteries, colloidal batteries, three-dimensional lithium ion batteries and lithium iron phosphate ion batteries. 1, lead-acid battery: plate of lead-acid battery is made of lead and lead oxide, electrolyte is aqueous solution of sulfuric acid. The important advantage of lead-acid battery is relatively stable, and the price is relatively inexpensive, high security, and currently dominates in the use of solar street lamp industry.

The valve-controlled lead-acid battery occupies the dominant position 2 in the use of the solar street lamp industry battery, colloidal battery: It is equivalent to the upgraded version of the lead-acid battery, which is maintenance-free, and it is important to replace the colloidal electrolyte replace the sulfuric acid electrolyte. In terms of storage capacity, discharge, safety performance, and life of life; the full name of its temperature is widened, the colloidal battery can be used in the temperature range of -40 ¡ã C - 65 ¡ã C, low temperature performance, The colloidal battery is the best choice in the tropics of the northern allergy or high temperature; its seismic performance is also very good, it can be safely used under various harsh conditions, and the service life is a common lead-acid battery. More.

3, three yuan lithium-ion battery: there are many advantages of the three yuan lithium ion battery, it is high, small size, fast charging, high price. It is about 500-800 times in the deep cycle, life and colloidal batteries are similar, and the temperature range used in -15 ¡ã C-45 ¡ã C. However, there is also a malpractice in terms of three-yuan lithium-ion batteries.

If there is less stable in the inside of the battery, or the unqualified manufacturer's ternary lithium-ion battery, it is very likely to be in an overcharge process or a high temperature environment. Probable explosion. 4, lithium iron phosphate ion battery: higher than that, small size, fast charging, good stability, the temperature applies range, but price is the highest in all batteries.

At present, due to its cost problem, there is no massive implementation. 2, how to use solar street light storage battery due to the current lead-acid battery (or the valve-controlled lead-acid battery, the valve-controlled battery) is still dominant, we will focus on the principle of the solar street lighting battery The purpose is to store the electric energy from the solar panel assembly, and release the energy to meet the lighting lighting when the light is insufficient or night lighting. The choice of battery capacity is generally followed: 1.

The battery should match the solar panel, with electric load (street light). The battery capacity is too small to satisfy the lighting of night lighting, the capacity is too large, and the battery will always be in the loss. The selection is very important.

If it is not determined, we can consult our sales engineer 2. The power of the solar panel must be more than 4 times higher, the system can work properly; the voltage exceeds the operating voltage of the battery 20% -30% to force Guaranteed normal battery. 3.

The capacity of the battery must be more than 6 times higher than the load annual consumption. 3, how to maintain the battery in the later period is also in the process of use, we also want to make reasonable maintenance of the battery to better extends its performance, extend its life. The battery is reasonable during use to exert its function, and the longevity of its life is to prevent the battery life of the overchallar street lamp.

In addition to the external maintenance, it is closely related to the internal heat accumulation, solar storage batter If the charge, the temperature inside the battery will rise step by step, and the phenomenon of thermal out-of control will occur. If you are serious, it is possible to shorten the life of the battery, or even abolish the battery. If we want to prevent battery overall, we must strictly follow the manufacturer's instructions to supply the charging voltage value.

2, to prevent the charging insufficient solar cells to prevent prevention of insufficient charging. It is also possible that the rack system has been charged in addition to the problem, or the voltage is too low. Frequent charging can result in a reduction in the number of cycles of the battery, and will shorten the life of the battery.

3, to prevent the discharge depth of the over-the discharge battery and the number of battery design charge and discharge cycle (service life) is closely related. If it is excessive discharge, the shorter life of the battery will, if severe words may cause the battery that there is no way to activate the best, even suddenly scrapped. 4.

Control the environmental temperature of a high temperature will shorten the life of the solar storage battery, so it is important to control the temperature of the solar cell. The battery life is relatively long, the battery is very guilty, the battery is crime. If the environment is relatively harsh, there is a very low temperature or extremely high temperature, it is best to choose a gel battery with a wide range of temperatu.
