Introduction to the structure of solar lithium-ion battery

Introduced the structure of solar lithium-ion battery.Solar lithium-ion battery uses three or four series of lithium-ion batteries. The battery packs together with 12V lamp. Solar lithium-ion battery capacity. According to the capacity of a single cell or the parallel connection of the battery capacity, the battery is guaranteed It is a safe, environmentally friendly, and if ternary three series street lamp solar battery combination nominal 11.1V lithium ion battery pack, but the industry calls it 12V lithium ion battery, such as 4 series lithium ion battery, lithium iron phosphate composite material after design The nominal 12.8V street lamp type solar lithium-ion battery pack is also called 12v battery by the lithium industry. The charging voltage of solar lithium ion battery is 12.6V, the discharge termination voltage is 9.0V, and the charging voltage of 12V lithium iron phosphate lithium ion battery is 14.6V, and the discharge termination voltage is 10V. The battery price is higher than that of the ternary material phosphoric acid. Fe-lithium-ion batteries, ordinary street lamps are now the mainstream ternary materials. They are not carbon dioxide and sulfur dioxide emissions, nor are there traditional power generation, noise, solid waste and other pollution. It is one of the important renewable energy technologies. The characteristics and applications of solar lithium-ion batteries: using intelligent control unit (lithium-ion battery capacity 1200wh or higher), the use temperature range of -25 to 55 ℃, the service life of the lithium-ion battery reaches more than 3 years, the street lamp battery shell is waterproof, Moisture-proof, anti-corrosion, heat preservation, heat insulation and other functions, when street lamp battery products and standard connectors, the instrument and the wrong protection level are IP65. The solar lithium-ion battery is processed by ternyuan18650 lithium-ion battery plus protection board, accessories, connecting devices, etc., and the matching intelligent control system is also called controller. Its working voltage is DC12V10A, and the single-chip microcomputer is used to realize the protection of the lithium-ion battery. 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 the 12v lamp solar energy is equipped with a lithium-ion battery Users of online 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-ion batteries and prevent flammability and explosion. It has a single cell independent voltage detection and protection function. Solar lithium-ion battery connection details: The street lamp solar lithium-ion battery output has two black waterproof connectors, which can be connected to the solar photovoltaic panel and the solar panel to connect to the battery. When the daylight is strong, the lithium-ion battery, the lithium-ion battery, and the other A black waterproof connector is the power supply system, solar street lights can make special lithium-ion battery solar lights, solar street lights power supply, so that it can emit light when it has electricity.
