The solar lithium battery uses three or four series of lithium batteries. The battery pack is connected in parallel with the 12 V lamp solar lithium battery capacity. According to the capacity of a single cell or battery capacity, it is connected in parallel to ensure that the battery is a safe, environmentally friendly, and if ternary three series The 11.1 V lithium battery pack in the name of the street lamp combination, but industry insiders call it a 12 V lithium battery, such as the 4 series lithium battery. After the design of the lithium iron phosphate composite material, the nominal 12.8V street lamp solar lithium battery pack is also called the lithium industry. 12V battery.

　　Solar lithium battery

　　The charging voltage of the solar lithium battery is 12.6 V, the discharge termination voltage is 9.0 V, the charging voltage of the lithium iron phosphate battery is 12.6 V, and the discharge termination voltage is 10 V. This is related to the price of the battery higher than that of the lithium iron phosphate battery. The ordinary street lamp is now three yuan The mainstream of materials, it neither emits carbon dioxide and sulfur dioxide, nor does it have traditional power generation, noise, solid waste and other pollution. It is one of the important renewable energy technologies.

　　The characteristics and application of solar lithium battery: use intelligent control unit (lithium battery capacity 1200 wh or higher), meet the temperature range of-25 to 55 ℃, the service life of the lithium battery reaches more than 3 years, and the street lamp battery shell is waterproof and moisture-proof , Anti-corrosion, heat preservation, heat insulation, and other functions, street lamp battery products and standard connectors, meters and error protection categories are IP65.

　　The solar lithium battery is processed by Tengyuan protection board, accessories, connecting devices, etc. The supporting intelligent control system is also called a controller. Its 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, space, instrumentation, trickle charge protection, undervoltage protection, overvoltage protection, short circuit protection, waterproof protection, etc. At the same time, 12 v solar light is equipped with lithium battery online Monitoring and functions that can be set by the user at any time are convenient for debugging and maintenance. The later system adopts double protection to ensure the safety of the lithium battery and prevent flammability and explosion. It has a single cell independent voltage detection and protection function.

　　Solar lithium battery connection details: street lamp solar lithium battery output, there are two black waterproof connectors, you can choose solar photovoltaic panel and solar panel to connect to the battery, when the daylight is strong in the sun, the rechargeable lithium battery, the lithium battery, and the other black waterproof The connector is a power supply system, solar street lights can be made of special lithium batteries, solar lights, solarCan lights to supply power, so that it can emit light when it has electricity.
