Detailed explanation of the structure of 12V street lamp solar lithium ion battery

1. 12V street lamp solar lithium ion battery is a battery pack composed of 3 or 4 lithium ion batteries in series. The capacity of 12V street lamp solar lithium ion battery is determined by the capacity of a single battery cell or the capacity of batteries connected in parallel. , Is a safe and environmentally friendly new type of battery, if the combination of 3 series of ternary batteries is nominally called 11.1V street lamp solar lithium ion battery pack, but the industry is commonly known as 12V lithium ion battery, if the iron phosphate lithium ion 4 string lithium ion battery After the combined design, it is called a 12.8V street lamp solar lithium-ion battery pack, which is also called a 12V lithium-ion battery in the industry. 2. The full charge voltage of the ternary 12V street lamp solar lithium-ion battery is 12.6V and the discharge cut-off voltage is 9.0V, while the full charge voltage of the lithium iron phosphate 12V lithium ion battery pack is 14.6V, and the discharge cut-off voltage is 10V, which is related to the battery. In terms of price, the price of lithium iron phosphate is higher than that of ternary material batteries, and now ordinary street lights use mainstream ternary materials, which do not emit CO2 and SO2, and do not have the noise, solid waste and other pollution of conventional power generation. It is one of the most important renewable energy technologies at present. 3. Features and applications of street lamp solar lithium-ion battery: using intelligent control unit (lithium-ion battery capacity ≥1200Wh), the use temperature range is between -25-55℃, the service life of lithium-ion battery reaches more than 3 years, street lamp battery shell It has the functions of waterproof, moisture-proof, anti-corrosion, heat preservation and heat insulation. The street lamp battery products use standard connectors when they leave the factory, which have the functions of anti-reverse and anti-wrong connection, and the protection level is above IP65. 4. The 12V street lamp solar lithium-ion battery is produced by using a ternary 18650 lithium-ion battery plus a protective board, auxiliary materials, and connecting devices. The intelligent control system that matches it is also called a controller. Its working voltage is DC12V10A. The single-chip microcomputer is used to realize the protection of the lithium-ion battery. The basic functions must have overcharge protection, overdischarge protection, light control, time and space, anti-reverse connection, charging trickle protection, undervoltage protection, overvoltage protection, short circuit protection, waterproof protection, etc., and 12V street lamp solar lithium ion battery adopts Online monitoring and users can set functions at any time to facilitate later debugging and maintenance. It adopts a dual protection system to ensure the safety of lithium-ion batteries, prevent inflammability and explosion, and has a single cell independent voltage test and protection function. 5. Wiring instructions for street lamp solar lithium ion battery: The street lamp solar lithium ion battery output has two black waterproof connectors, one can be connected to the solar photovoltaic panel, so that the solar panel can be connected to the battery, and the lithium ion battery can be connected when the sun is strong during the day. Charge it to store the lithium-ion battery. The other black waterproof connector is the power supply system of the solar street light, which allows the special lithium-ion battery for the solar street light to power the solar lamp beads so that it can shine when it has electricity.
