Solar street light rechargeable battery
At this stage, the development trend of lithium battery in China is in the development stage, the accumulation is insufficient, the characteristics of lithium battery packs are improved and the production process is still not perfect, and it is necessary to develop and improve products for a long time. Let's take a look at the advantages and disadvantages of solar street light lithium batteries.
First, let's take a look at the key advantages of lithium batteries:
1. The kinetic energy of street lamps is relatively high. With high storage ratio energy, it has achieved 460-600Wh/kg at this stage, which is about 6-7 times of lead-acid battery;
2, the use period is long, the use period can be achieved for about 6 years, lithium iron sulfate is a positive rechargeable battery 1C (100% DOD) discharge, there are records that can be applied 10,000 times;
3, the rated current is high (competition rate operating frequency is 3.7V or 3.2V), which is equal to the serial working voltage of three nickel-cadmium or nickel-hydrogen rechargeable batteries, which is beneficial to constitute a rechargeable battery switching power supply group;
4, with high power bearing capacity, in which the lithium iron sulfate battery for pure electric vehicles can achieve 15-30C discharge working capacity, which is conducive to the acceleration of high toughness;
5, the self-discharge rate is very low, it is one of the most prominent advantages of the rechargeable battery, at this stage can generally guarantee 1% / month below, not 1 / 20 of the nickel-hydrogen battery;
6, very light, the same volume of net weight is about 1/5-6 of lead-acid products;
7. The high-low temperature test of the solar street lamp has strong adaptability and can be applied in the natural environment of -20°C--60°C. It can be applied in the natural environment of -45°C after being solved by the processing technology.
8, low-carbon environmental protection, regardless of manufacturing, application and reporting fees, does not bring, do not cause all harmful chemical and chemical substances such as lead, mercury, cadmium, and other harmful hazards. 9. The basis of production and manufacturing does not consume water. It is very beneficial for China to have less water.
