Problems solved by technology

[0002] Solar lighting products have been widely used by people at present. Among the many known solar products, it is not difficult to find that most of the solar lights cannot avoid the light-off situation in continuous rainy days.
In the case of not using mains power supply to street lamps, the influence of weather becomes very important. Traditional solar lamps can only last for 4-5 days in rainy days.

example 1

[0036] Example 1: The temperature of the day is 22 degrees to 26 degrees, the battery is 35AH / 12.8V lithium iron phosphate battery, the power is fully charged before installation, the solar panel is 150W solar panel, and the test LED light board PID tracking discharge current is set to Itest=2.5A , data integration is performed on the output power of the lithium battery, that is, the output current and voltage per second are multiplied and accumulated, and the transient power per second is calculated PS=3.78*13.32=50.3496W, which passes the actual test C MAX =C BAT =PS*Ttest=449.5Wh (Ttest is the cumulative time calculated for discharge completion), the capacity test is completed. Turn on MPPT charging at dawn the next day, and calculate the charging power value P by integral calculation. When night comes, the solar panel voltage V PV n =405.2Wh, at this time C n / CMAX>25%, the battery temperature parameter T is 1, the MCU calculates the discharge capacity of the lithium bat...

Abstract

The invention provides a dichotomy-based solar lamp system control method with sustainable lighting. The battery capacity is calculated by using integral, the data is more accurate, at the same time,the discharge capacity of the battery is controlled by a time period and dichotomy, the capacity of the battery is reasonably utilized, so that a solar lamp of a system can still be lit for a long time in continuous rain days, and the battery life is long.

Description

technical field [0001] The invention relates to the field of solar lamp system control methods, in particular to a solar system control method based on dichotomy for sustainable lighting. Background technique [0002] Solar lighting products have been widely used by people at present. Among the many known solar products, it is not difficult to find that most of the solar lighting cannot avoid the light-off situation in continuous rainy days. In the case of not using mains power supply to street lamps, the impact of weather becomes very important. Traditional solar lamps can only last for 4-5 days in rainy days. When the battery and solar panels are determined, how to ensure the long-term stable operation of solar lamps is very important. Contents of the invention [0003] The object of the present invention is to provide a solar lamp system control method that can keep the lamp on for a long time in continuous rainy weather. [0004] The technical solution of the present...
