How to maintain lithium batteries for solar street lights?

With the continuous development of science and technology, the technology of lithium battery integrated solar street lights is becoming more and more mature, with larger and larger capacity, longer life span, and wider application range. Nowadays, the use of lithium batteries has developed into the solar street lamp industry, replacing lead-acid and gel batteries. How to use and maintain lithium batteries is very important to extend the life of solar street lamps. 1. Lithium battery for solar street lights is overcharged. What is meant by overcharge, that is, the charging current of the lithium battery is greater than the acceptable current of the battery. This overcharge will be converted into heat and increase the battery temperature. This will easily cause thermal runaway for a long time. The capacity of the lithium battery is drastically reduced and deformed, and there are hidden dangers of explosion and combustion. Therefore, it is necessary to guard against overcharging of the lithium battery, supply the charging voltage value in strict accordance with the regulations, and make overcharge protection. 2. The lithium battery for solar street lights is not advisable to over-discharge and over-charge, and over-discharge is also undesirable. The deeper the depth of over-discharge, the shorter the number of charge-discharge cycles, that is, the service life, because over-discharge will cause the internal pressure of the lithium battery. Increased, causing the reversibility of the positive and negative active materials to be destroyed, electrolyte analysis, negative lithium deposition, resistance will increase, even if charging can only be partially restored, its capacity will be clearly attenuated, or even directly scrapped. If you want to maintain the lithium battery from this perspective, you can install a BMS system in the battery. This system can adjust the battery voltage, effectively balance the voltage and current between the batteries, and guard against over-discharge. Third, solar street lights use lithium batteries to control the ambient temperature. Whether the ambient temperature is too high or too low, it will also affect the capacity of the lithium battery and shorten its service life. First of all, it is best to choose a lithium battery instead of a gel battery in terms of battery selection. Lithium batteries have better performance in terms of cold resistance and heat resistance.
