1. Lithium battery is small in size and light in weight, saving time and effort
At present, the preferred choice for global solar street lamps is generally integrated street lamps. If a lead-acid battery pack is used, it needs to be buried in the underground near the pole and placed in the buried box. If a lithium battery is used, with its light weight, It can be externally attached to the back of the panel, saving time and effort.
2. Lithium battery is less polluted than lead-acid battery, green and environmentally friendly
We all know that the life of lead-acid batteries is short, it is cheap, but it may be changed once a year, which will greatly increase the pollution of the environment. Moreover, the lead-acid battery itself is heavier than the lithium battery, and if it has been changed, it will always cause harm to the environment. Lithium batteries are not polluted, while lead acid batteries are contaminated with heavy metal lead.
3. Lithium battery is more intelligent
At this moment, the lithium battery has become more and more intelligent, and the function is getting more and more perfect. At this moment, the lithium battery can be adjusted according to the user's demand for the battery, the length of use, and the like. A large number of lithium batteries can be installed with a BMS management system. The status of the battery can be checked on the mobile phone in real time. The current and voltage of the battery can be detected autonomously. If there is an abnormal situation, the BMS system can automatically adjust.
4. Lithium battery life is longer
The annual loss of lead-acid batteries is high, and it often needs to be changed once in a year or two. Lithium batteries have a service life of 3 to 5 years, and generally can be guaranteed for three years. The lead life of lead-acid batteries is at 300 times. The lithium iron phosphate battery has a 3C cycle life of more than 800 times.
5. Lithium battery is more secure, no memory effect
Lead-acid batteries are easy to enter, and lithium batteries are not easy to enter. Moreover, the lead-acid battery is memory-bearing, that is, the charging effect occurs when charging is not completely discharged, which may affect the service life of the battery. The lithium battery is not memory and can be charged at any time. This makes it safer and more reassuring. Lithium iron phosphate has undergone rigorous safety testing and will not explode even in severe collisions.
6. Lithium battery energy density is high
Lithium batteries have a high storage energy density, which has reached 460-600 Wh/kg at this time, which is about 6-7 times that of lead-acid batteries. This will better store energy for solar street lights.
7. Lithium battery solar street lights are very resistant to high temperatures
Solar street lights are exposed to the outside every day, so there is a higher demand for temperature environment. The lithium iron phosphate battery has a hot peak temperature of 350 to 500 ° C and can be used in an environment of -20 ° C to 60 ° C.
8. The price, warranty period
At present, the mainstream battery on the market is 48 volts. If it is changed, the lead-acid battery is 450 yuan, and the warranty period is 1 year. The price of the lithium battery is relatively expensive, and it needs 1000 yuan, but the warranty period is two years.
