Do you know anything about the capacity calculation method of lithium-ion batteries?

Q--Required configuration of lithium battery capacity (Amp-hour); p--load power (watts); t--hours of daily electricity consumption; U--standard lithium battery voltage (usually 12 volts); n--battery Reserve cycle coefficient; (determined according to wind conditions, generally 3~8 days) K--discharge control coefficient, (take 0.75~0.8) The above formula takes into account: ①Rated power of electrical equipment, ②Local weather conditions, namely The average time of the no-wind period, ⑧In order to prevent the over-discharge of the lithium battery, the discharge should be controlled to a certain extent. For example, install a 100-watt machine to supply electricity to 3 households, and install two 12-volt 15-watt light bulbs in each household for an average of 5 hours of lighting per day, and calculate the required lithium battery capacity. (The reserve factor is taken as 6, and the discharge control factor is taken as 0.8.) Substituting into the formula: 6 l2V 48Ah lithium batteries with a total capacity of 288Ah. 2. Power balance calculation method. The calculation steps are as follows: a. According to the wind speed data provided by the local meteorological department, taking ten days as an hour, count the number of hours of different wind speeds from the initial working wind speed to the stop wind of the wind turbine ten days. b. According to the Pu003df(V) characteristic curve and wind speed data of the selected wind turbine, calculate the amount of electricity that a machine can generate every ten days, and draw the curve of its annual power generation process. The annual power generation process line of Shangdu Mu Machinery Factory ED1.5~100 wind turbines calculated and drawn based on wind speed data. It is calculated that under the local wind conditions, the annual power generation of the aircraft is 276 degrees. It can be seen from the process line that the amount of power generation varies greatly in each ten-day period. The highest is 19 degrees in late April, and the least is only 0.95 degrees in late February, a difference of nearly 20 times, indicating that it is necessary to configure lithium batteries for energy storage adjustment. C calculates the electricity consumption by ten days according to the telecommunications conditions, and gives the annual electricity consumption process line. The dotted line in the figure shows. d. Compare the power generation and the power consumption process line, and determine the required lithium battery capacity by using the power generated less than the time when the difference in power consumption is the largest (the oblique line in the figure).
