3. 2 volts formula of solar street light

In the progress of science and technology, the application range of the battery is becoming more and more widely, talking about the battery, I'm afraid most people's first impression is common battery, remote control, later contact, know and rechargeable batteries, battery, and on the phone at present almost unified

along with the advance of science and technology, the application range of the battery is more and more widely. When it comes to battery, I'm afraid most people's first impression is ordinary dry-cell batteries and remote control. Later, they are exposed to more rechargeable batteries, battery and lithium battery, the battery is used in almost all mobile phones. You can see that the lithium battery place in this industry has its unique advantages, now they have been applied in the street. Let's take a look at the lithium battery solar street lamps. First of all, lithium battery energy storage density high, light weight, easy installation I remember descriptions of lithium chemistry class: white metal, soft, is the lowest density of metal; Metal is one of the most active. Lithium battery is obvious: the advantages of high working voltage, small volume, light weight, high energy, no memory effect, no pollution, low self-discharge, long cycle life. Today's solar street lamp, if use lead-acid batteries, due to its huge size, need to be buried underground around the light pole, and if you use lithium batteries, due to its light weight, can be hung on the other side of the panels, save time and effort. Lithium battery energy storage density high, up to 460 - 600 watts/kg, is 6 - of lead-acid batteries Seven times. Second, lithium battery controllable pollution-free, so far, lithium battery, no pollution and conventional lead-acid battery is heavy metal lead pollution. In addition, short service life of the lead-acid battery, and lithium battery service life generally in more than 10 years, and the service life of led light source is in more than 10 years, can be a good match. Third, lithium battery is intelligent traditional solar street lamps using solar energy, compared with the traditional street lamps energy-saving, but affected by the weather. However, if the solar street lamps use lithium battery, can according to user requirements of intelligent optimization of battery capacity, the use of factors such as time, weather conditions, reasonable distribution of electricity, light control, time control, memory storage, and other functions, guarantee the rainy day lighting 10 consecutive days. Fourth, strong adaptability to the temperature of the lithium battery of lithium battery temperature adaptability is very strong, even if - in the north 45 ℃ cold environment, also can in - 20℃- 60 ℃ under the environment of work. 5. Lithium battery safer than lead-acid batteries, lithium battery is a kind of controllable and pollution-free energy storage batteries, than lead-acid batteries more stable and safer. ； Natural selection, survival of the fittest. Obviously, lead-acid battery and gel battery far can't satisfy people's growing demand. The continuous development of science and technology to promote the solar street light industry forward, we still need to continue to promote the solar street light industry.
