As lithium battery technology is more and more mature, capacity is more and more big, the life is more and more long, now the use of lithium-ion batteries have been conducted to solar street lamp, instead of lead acid and colloid storage battery. Why so many people choose solar lithium battery? Is also a storage battery, why do you choose to lithium-ion batteries more than lead-acid battery? Solar street light industry is now developing more faster, lithium battery is a kind of controllable type, non polluting energy storage batteries, new type of lithium battery of solar street light can match with the system. Jiangsu zhongshan solar lamp factory solar street lamps factory here share some understanding of the two kinds of battery, for your reference. A, lithium battery
in many performance than lead acid battery is without a doubt, the lithium iron phosphate battery is common at present, the battery is not like a lead-acid battery memory effect, after more than 1000 times charging and discharging, storage capacity of the battery still can reach 85%, compared with lead-acid batteries, lithium batteries have the advantages of light, large capacity, long using time.
2, lead-acid battery
electricity is mainly composed of lead oxide, the electrolyte is sulfuric acid solution. Lead-acid battery charged state, is the main component of lead dioxide and a negative main composition as the lead; Put on some condition, the positive and negative are the primary components of lead sulfate. Lead-acid batteries with memory effect, at the time of overlap, more than 500 times, the battery storage capacity will be greatly reduced.
3, why do you choose of lithium-ion batteries more than lead-acid battery?
1, the lithium battery small size light weight, installation time
now generally choose one-piece street lamp, solar street lamps with lead-acid battery pack, need to be buried underground around the light pole, placed in the ground inside the box, and if use lithium battery, with its lighter weight, can be external to the panels opposite, save time and effort.
2, lithium battery is smaller than lead-acid battery pollution, green environmental protection
we all know that the service life of the lead-acid battery is shorter, although it is cheap, but may have to change once a year, this will greatly increase the pollution to the environment. And lead-acid battery itself is heavier than lithium battery pollution, if has been changed, will cause harm to the environment. Lithium battery without pollution, while lead-acid batteries with heavy metal lead pollution.
3, lithium battery smart li-ion battery
now has been more and more intelligent, function also is more and more perfect. Now lithium-ion batteries can be based on user demand for batteries, hours used, etc. Many lithium battery can be installed a BMS management system, can real time on the phone to check the battery status, can also be independent current of battery voltage, if there is any abnormal situation, can automatically adjust the BMS system.
4, lithium battery with long time
lead-acid battery in loss is higher, often need to change a year or two. And the service life of the lithium battery has 3 & ndash; — Five years, is to all warranty for three years. Cycle life of lead-acid battery at about 300 times. The lithium iron phosphate battery, 3 c has a high cycle life.
5, lithium battery high safety, no memory effect,
lead-acid battery into water easily, lithium battery is not easy to fill. And lead-acid battery is a memory, is also not discharge charge will produce a memory effect, can affect the service life of batteries. And the lithium battery is without memory, can charge at any time. So to use and safety, and reassuring. Lithium iron phosphate has been rigorous safety testing, even in violent collisions, also won't produce explosion.
6, high lithium battery energy density
lithium battery with high energy storage density, now has reached 460 - 600 wh/kg, it is about 6 - lead-acid batteries Seven times. It will be good for solar street light energy storage.
7, lithium battery, solar street light is high temperature resistant
solar street light bare outside in the sun every day, so the requirements of high temperature environment. Lithium iron phosphate battery heat peak is 350 ~ 500 ℃, can in - 20℃- - 60 ℃ under the environment of use.
8, price, warranty aspects on the market at present the mainstream is 48 v batteries, lead-acid battery is controlled 450 yuan, if in warranty period for 1 year; Lithium-ion batteries are relatively expensive, need 1000 yuan, but the quality assurance period for two years.
4, overall solar street lamps lithium-ion batteries advantages
✔ adjustable solar panels stents, big limit increase light collection;
✔ green;
✔ lithium battery installation is convenient to install solar panels directly under the, small volume light weight reducing construction cost cost;
solar street lamps ✔ long life 3 - is one of the traditional energy storage lead-acid batteries 5 times;
✔ resistance to high and low temperature can be in - 20℃- 60 ℃ environment use, can in - seiko other technics 45 ℃ environment use;
✔ maintenance free performance is good.
the above is about lithium battery compared to the advantages of the lead-acid battery was introduced to this, the lithium battery is a type of energy storage batteries, controllable than the lead-acid batteries, safe.
the lithium battery and popular among customers, are also recognized lithium battery. The lithium battery has become a development trend of solar street lamps after selecting lithium battery as energy storage device of solar street light will be more and more.
