What kind of battery does solar street light use? solar street light-li

With the in-depth development of the new socialist countryside and the construction of beautiful countryside, solar street light has been seen everywhere as the preferred lighting equipment. Solar street light is not only energy-saving and environmentally friendly, but also does not generate electricity bills, so it has been welcomed by the general public. The battery is the main equipment of the solar street light. At present, the batteries used by the solar street light mainly include lead-acid batteries, gel batteries, ternary lithium batteries, and lithium iron phosphate batteries. So which battery is the best for the solar street light? ? First of all, let's take a look at the characteristics of these kinds of batteries: Lead-acid battery: The plate of the lead-acid battery is composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low price; its disadvantages are low specific energy (that is, the electric energy stored in each kilogram of battery), so its volume is relatively large, its service life is short about 300-500 deep cycles, and its daily maintenance is frequent. At present, solar street The light industry is still heavily used. Gel battery: It is actually an upgraded maintenance-free version of lead-acid battery. It replaces sulfuric acid electrolyte with colloidal electrolyte, which is improved compared with ordinary batteries in terms of safety, storage capacity, discharge performance and service life. Some of the prices are even higher than ternary lithium batteries. It can be used in the temperature range of -40℃--65℃, especially the low temperature performance is good, suitable for the northern alpine region. It has good seismic performance and can be used safely in various harsh environments. The service life is about double that of ordinary lead-acid batteries. Ternary lithium battery: high specific energy, small size, fast charging, high price. The number of deep cycles of the ternary lithium battery is about 500-800 times, the life span is about 1 times longer than that of the lead-acid battery, and the temperature range is -15℃-45℃. But the disadvantage is that it is not very stable, and the ternary lithium battery of unqualified manufacturers may explode or catch fire when it is overcharged or the temperature is too high. Lithium iron phosphate battery: high specific energy, small size, fast charging, long service life, good stability, and of course the highest price. The deep cycle charging times are about 1500-2000 times, the service life is long, generally 8-10 years, the stability is strong, the operating temperature range is wide, and it can be used at -40℃-70℃. Finally, the battery mentioned above must be selected according to the actual requirements of the on-site ambient temperature, and a regular manufacturer must be selected; we mainly produce and sell outdoor roads, squares, stations, docks, courtyards and indoor industrial and mining lighting fixtures. Varieties are: solar street light, led street light, single-arm light, double-arm light, high pole light, combination light, garden light, landscape light, lawn light, buried light, solar light, led light, led lamp holder, solar panel, Fountain sculptures, various traffic sign poles, traffic lights, power poles, and supporting ballasts and triggers, and also produce light-controlled and time-controlled switch boxes.
