Yang can choose from three lamps. 2 v lithium iron phosphate battery' Lithium iron phosphate batteries, refers to the use of lithium iron phosphate as the anode material of lithium ion batteries. 】 As the cause of the battery?

as countries the application of solar energy more widely, there are more and more solar street lamps factory ( tuwr。 com) , many manufacturers simply in the pursuit of commercial interests, not too much reserves of technology patents. Many manufacturers according to past experience or use 12 v of colloid lead-acid battery 【 Definition: the electrode is mainly composed of lead and its oxide, the electrolyte is a battery of the sulfuric acid solution. 】 And we TUWR figure has pioneered the use of 3. 2 v lithium iron phosphate battery' Of lithium iron batteries are a group of batteries, lithium battery in the family the anode material for lithium iron phosphate, and lithium iron batteries for short. 】 As the battery solar street lamps. Because outstanding in the business, we are a lot of our discredit on technology.

first we talk about a few low-level technical myth:

1, solar street lamps use 12 v battery than 3. 2 v lithium iron phosphate batteries have higher brightness

now I ask you a question a very common sense: automotive lamps and home lighting which high brightness?

car headlights generally 12 v or 24 v, all the lights in the house is 220 v, very low-level technology, common sense tells us that there is no direct relationship between the brightness and voltage.

2、3。 The structure of 2 v lithium iron phosphate batteries too simple

it didn't say wrong, 3. 2 v is some concise than 12 v system, the key is not this. As everybody knows, lithium iron series to the 12 v must be between the four batteries do internode protection and uniform flow balance, however, for the series of four batteries consistency requirements is very high, for each battery work when the temperature higher consistency requirements & ndash; — This solar lamp in the outdoor is difficult to guarantee. Yes, if it is indoor use laptop or outdoor electric car, you can use expensive BMS 【 Battery management system ( 电池管理系统) Battery management system ( BMS) Is the link between the battery with the user, the main object is the secondary battery, is mainly in order to improve the utilization rate of the battery, prevent the battery overcharge and over discharge, can be used for electric vehicles, storage battery, robots, unmanned aerial vehicles (uavs), etc. 】
