Many solar cells do not have good heat dissipation effect. If they are used in hot weather all the year round, they may be scrapped in two or three years. However, lithium-ion batteries have a very strong temperature adaptability, and they can work normally in the environment of - 20 ℃ - 60 ℃. And it can operate normally even in the cold weather in the north. It can withstand both the hot weather in the south and the cold weather in the north.
Lithium ion batteries are becoming more and more intelligent and their functions are becoming more and more perfect. Today's lithium-ion batteries can be adjusted according to the needs of users and the service life. Many lithium-ion batteries can be equipped with a BMS management system, which can check the battery status on the mobile phone in real time, and can also independently detect the current and voltage of the battery. In case of abnormal conditions, the BMS system can automatically adjust.
Lithium ion batteries are more stable and safe than other solar cells. Its heat dissipation effect is good. The lithium ion battery comes from the stability and reliable safety design of the positive electrode material. The lithium iron phosphate battery completely solves the potential safety problems of lithium cobalate and lithium manganate. The lithium iron phosphate has passed strict safety tests. It does not explode or ignite in puncture, extrusion, overcharge, short circuit and other experiments.
Now the times are developing faster and faster, and more and more people are advocating environmental protection, so lithium ion batteries have emerged. Compared with lead-acid batteries, lithium-ion batteries are pollution-free in production and use, comply with European RoHS regulations, and are green and environment-friendly lithium-ion batteries.
The service life of lithium ion battery is much longer than that of lead-acid battery. The cycle life of lithium ion battery is 1200~2000 times, but that of traditional lead-acid battery is only 500~900 times. The service life of ordinary lithium-ion batteries is 5-10 years, and even if they are well maintained, they can be used for more than 10 years. It will be better to use it with the LED light source of the solar street lamp!
