Does the lithium battery of solar street lights have a long lifespan? Two major reasons for the short lifespan of lithium batteries in street lamps.
Currently, many solar street light lithium batteries use automotive powered batteries, and many solar street light lithium batteries use BYD batteries, CATL lithium batteries, and Guanzhou BATTSYS lithium batteries. If the brand new power cell is used as a solar street light battery, its lifespan can reach 20 to 30 years. Let's take a detailed look at whether the lithium battery life of solar street lights is long? The reason for the short lifespan of lithium batteries in solar street lights.
Does the lithium battery life of solar street lights last long
Everyone knows that the national standard requires power batteries to be retired after a 30% attenuation, and then recycling plants classify them according to their quality and carry out cascading utilization. Since we are all using battery cells in a tiered manner, we will discount 30% of the cycle times and calculate based on one cycle per day (in reality, one cycle per day is not enough) to estimate the lifespan of the lithium-ion battery for power solar street lights. Most solar street lights have a discharge depth of 50%, at which point the lithium battery life of solar street lights can be as long as 7-11 years; When the discharge depth is 30%, it can last for 15-22 years. The new power battery for solar street lights can have a lifespan of 20-30 years.
Two major reasons for the short lifespan of lithium batteries in solar street lights
Below are two reasons why lithium batteries for solar street lights manufactured by some manufacturers have a short lifespan and are easily damaged. The main problem still lies in the selection of raw materials and processes.
1、 Selection of raw materials: mainly including battery cells and protective boards
The quality of cascaded power cells varies greatly. Professional solar street lamp lithium battery manufacturers must have the ability to screen battery cells, have strict screening standards, and conduct screening on each battery cell. The protective board must choose a good brand, with a balanced one.
2、 Standard preparation process for
lithium batteries for solar street lamps
Divide into parts. The most basic requirement is that each battery cell must be divided into capacity, which can select batteries whose capacity, charge discharge curve, voltage and other parameters do not meet the requirements.
Let it go quietly. The battery cells in the lower distribution cabinet must be left idle for 7 days.
Pairing up. There are strict grouping standards and they are consistently implemented comprehensively.
ageing. High current aging can simulate the operation of solar street light system software, by testing most components of the entire solar street light system software, including battery pack, protection board, controller, cables, and light source, in order to solve faults as much as possible in the factory. Below, let me introduce to you the parameters of a very good lithium battery for solar street lights. 24V 40AhF solar street light energy storage nickel hydrogen battery
