Structure analysis of 12V street lamp solar lithium battery

1Solar lithium batteries can be assembled into solar street lights with LED lights, street lights, solar panels, controllers, street light poles, signal sources, etc., street light solar lithium batteries are divided into integration, fission, 50w 30w, 100w, 30 ah according to different lighting control requirements , Ah, the lighting brightness of 60 different batteries, etc. Of course, we can also provide street lamp solar batteries in different voltages and different special lithium battery capacities according to the requirements of the system manufacturer. 2. The street lamp and solar lithium battery system are divided into: according to the voltage 12V lamp special lithium battery, solar street lamp solar special lithium battery 11.1V, 12.8V street lamp solar special lithium battery wholesale, according to the ability of self-meaning can make 20A street lamp solar special Lithium battery packs, 30 ah solar street lamp special lithium battery packs, 40 ah street lamp solar special lithium battery packs, 600 ah solar street lamp use lithium batteries, and street lamp solar energy use large-capacity lithium battery packs. Wait. 3. The application of the advantages of energy saving, environmental protection, safety and other advantages of solar lithium batteries for street lamps has become the new favorite of the urban road lighting industry, and the market potential is huge. In different regions, such as cities or villages, the lighting density requirements of lithium battery solar street lights are different, but the charging and discharging principles of lithium battery solar street lights, as well as the basic characteristics of lithium batteries. According to different requirements, important from practical and economical considerations, we can choose the corresponding capacity lithium battery solar street light configuration to suit the needs of the region. 12V street lamp solar lithium battery structure analysis solar lamp lithium battery structure 1, 12V lamp solar lithium battery uses three or four combinations of serial lithium batteries, batteries, 12V lamp solar lithium battery capacity, according to the capacity of a single cell or the parallel of battery capacity Connection to ensure that the battery is a safe, environmentally friendly, if the three-element series of street lamp solar cells pack a nominal 11.1V lithium battery pack, this industry is called 12V lithium battery, such as 4 series lithium battery, lithium iron phosphate composite design The later nominal 12.8V street lamp type solar lithium battery pack, also known as 12V lithium battery in the industry. 2. The charging voltage of the 3 yuan 12V lamp solar lithium battery is 12.6V, the discharge termination voltage is 9.0V, and the 12V lithium iron phosphate battery charging voltage is 14.6V, the discharge termination voltage is 10V, which is related to the battery price is higher than the ternary material Lithium iron phosphate battery is now the mainstream ternary material for ordinary street lamps. It does not emit carbon dioxide and sulfur dioxide, nor does it have conventional power generation, noise, solid waste and other pollution. It is one of the important renewable energy technologies. 3. The characteristics and application of lithium battery solar street lights, using intelligent control unit (lithium battery capacity 1200wh or higher), the use temperature range to meet -25 to 55 ℃, lithium battery life of more than 3 years, street lamp battery shell waterproof, Moisture-proof, anti-corrosion, heat preservation, heat insulation and other functions, street lamp battery products, when they are connected to a standard joint, the correctness of the meter and the protection level are IP65. The 4.12V street lamp solar lithium battery is composed of a three yuan 18650 lithium battery plus a protection board Auxiliary materials, connecting devices, etc. are produced. The matching intelligent control system is also called a controller. The working voltage is DC12V10A, and the protection of the lithium battery is realized through the single-chip microcomputer. The basic functions must have overcharge protection, discharge protection, electrical, time and space, meter, trickle charge protection, undervoltage protection, overvoltage protection, short circuit protection, waterproof protection, etc., and 12v solar energy is equipped with lithium battery online Users of monitoring and functions can be set at any time, which is convenient for debugging and maintenance. The later system adopts double protection to ensure the safety of the use of lithium batteries and prevent inflammability and explosion. It has a single cell independent voltage detection and protection function. 5. Street lamp and solar lithium battery connection details: The street lamp solar lithium battery output has two black waterproof connectors, one can be connected to the solar photovoltaic panel and the solar panel are connected to the battery, when the strong sunlight in the daytime shines on the lithium battery, it can be Charged, recharge the lithium battery statement: Some pictures and content of the articles published on this site are from the Internet.
