Yufai: What are the battery advantages of solar street lights?

The advantages of solar power street lamp, batteries can be divided into the following points:

1. Lithium battery has high voltage and light weight. The average voltage of a single battery can reach 3.7V or 3.2V, which is relatively equal to the series voltage of 2-4 nickel-hydrogen batteries or nickel-isolated batteries.

2. The energy and density of lithium batteries are also high for other batteries. Lithium batteries have a high energy storage density. Currently, the commonly used lithium batteries have a density of 450-620Wh/kg, which is 5-7 times that of lead-acid batteries. If people choose batteries, they will also consider a very important issue, that is, pollution.

3. Compare the battery weight. The weight of a lithium battery is about 5-6 times that of a lead-acid battery. Although the weight of lithium batteries is not much different from the weight of polymer lithium batteries. But looking at capacity and life, people will choose lithium batteries.

4. The service life of lithium battery is very long. If there is no accident, the service life of a lithium battery can be used for more than 6 years, up to 9 years. The normal number of uses is more than 1000 times. If there is no accidental use, it can reach more than 1500 times.

5. Low self-discharge and no memory effect. In the production of lithium batteries, adding a protective plate to the lithium battery can make the lithium battery have an overcharge and overdischarge effect. Lithium battery itself has high power

endurance.

The 100w led solar street light, lithium battery has quickly occupied the solar street light market due to its safety, light weight, long service life, complete charge and discharge, low maintenance cost, and no memory effect. Compared with traditional lead-acid batteries, lithium batteries have the characteristics of pollution-free, long life, no memory effect, more charge and discharge times, and longer life. For example, compared with a lead-acid battery of the same capacity and a lithium battery, the number of charge and discharge times of a lead-acid battery is 400 times, while a lithium battery can reach about 1,000 times, which is nearly three times that of a lead-acid battery, so the lifespan is also close to that of a lead-acid battery. Tripled.
