How do you calculate the voltage, capacity and watt-hour of lithium battery?

How do you calculate the voltage, capacity and watt-hour of lithium battery? As the advocate of saving energy and environmental protection, new energy products are marketed, and energy-saving products has become the trend. In the new countryside of solar street lamps with lithium battery nearby, compliance orientation elements are no more than an obstacle to the solar panels. This is the day in the sun shine, solar energy battery components has satisfied the daylighting of the size and daylighting. The second point is the basis of the partial drainage function is good, it can't have too much of a part of the equipment of water piled up, so all affect the safe sex of street lamps for a long time. The foundation unsafe seemed at sixes and sevens. Other new rural solar street lamps are not municipal electric power demand, so it don't need any influence from other public facilities to each other.

On the above, lithium battery chooses pool solar street lights, in addition to guarantee the system stability has an intention is to maintain the battery, not a lot of water. Because most of the time the battery embedded, if there is a lot of water is short in the battery box, and then affect the normal operation of all system and battery life, it needs pay attention to every detail. As long as every step * to focus on results, ensure lamps using time is longer, this is very good for us.

Lithium battery solar street lamps system: solar panels (bracket), battery, controller, LED light source, light pole, etc. Li - ion of solar street light quotation based on the detailed parameters of each component, so how about lithium battery capacity calculation of solar street lamp details are as follows:

Peak panel demand (WP) :

Lighting time is 7 hours each night (h);

For example, the panel lighting time was 4.5 hours per day (note: the Yangtze river area of obscene and indecent 4.5 hours).

It is necessary to relax 20% storage space.

WP is now 17.4 V = (5 * 7 h * 120%), now is 4.5 h

WP17.4V=9.33

WP=162(W)

Tube account:

For example: 12 v battery system;So if you have 30 w, you have 60 w.

Now I'm 60 w12v = 5

3, simplified formula

Lithium battery of solar street light battery components in = power supply * moment/local peak sunshine * loss coefficient (1.6 2.0)

= to use in the rain power battery capacity 

Tube capacity:

For example: light time is seven hours per night (h)

Satisfied with 5 day lighting (+ 5 days rainy night lighting, 6 days)

Battery = 5 * 7 h * (5 + 1)

This is 5 * 42

= 210!

What is a lithium battery capacity?

Monomer: lithium battery capacity generally refers to the temperature of 25 + 2 ℃, humidity: (65 +) 20 ﹪ RH of the environment, to 0.5 C constant current charging to 3.65 V, constant voltage charging to the current 0.01 C as; Electric power lithium batteries with a 0.5 C or 1 C discharge current case, the battery can be stored or tile hours, capacity range allows the deviation of plus or minus 3%.Lithium battery voltage, capacity, watt hour how to calculate?
