Embodiment Construction
[0015] figure 1 It is a flow chart of a solar charging method according to an embodiment of the present invention. Please refer to figure 1 , first initialize an indicated current value (step S101), and control a solar charging unit to charge a battery according to the indicated current value (step S102). Then monitor an actual current value at which the battery is actually charged (step S103 ). Next, continuously determine whether the actual current value is greater than the first critical value, wherein the actual current value is positively correlated with the indicated current value (step S104 ). When the actual current value is greater than the first threshold value, the indicated current value is incremented by a unit of a first preset current change value to increase the actual current value (step S105 ).
[0016] And when the actual current value is equal to or less than the first critical value, the indicated current value is decremented by the unit of the second p...

The invention discloses a solar energy charging method and a device thereof. The method comprises following steps: initializing an indicator current value; controlling a solar energy charging unit to charge a battery according to the indicator current value; monitoring the value of the current, which is actually accepted by the battery; continuously judging whether the actual current value is larger than a critical value, there being a positive correlation between the actual current value and the indicator current value; when the actual current value is larger than the critical value, taking the first preset current change value as the unit, and increasing the indicator current value to increase the actual current value; when the actual current value is equal to or smaller than the critical value, taking the second present current change value as the unit, and decreasing the indicator current value until the actual current value is larger than the critical value, the indicator current value being a stable indicator current value at this moment; controlling the solar energy charging unit to continuously charge the battery according to the stable indicator current value; and thus the battery is charged by the present optimum output of the solar energy charging unit.
Description
【Technical field】 [0001] The invention relates to a solar charging method and its device, and in particular to a solar charging method and its device which can automatically adjust the charging current. 【Background technique】 [0002] As a new energy source, solar energy has always been regarded as a potential alternative energy source due to its environmental protection characteristics. The application of solar energy is becoming more and more extensive, such as solar lighting devices, solar charging devices, and automobiles driven by solar energy. [0003] Generally speaking, the application of solar energy requires a solar panel to receive sunlight and convert it into electricity. The power that solar panels can provide varies with the current illuminance provided by the sun and the surrounding ambient temperature. For example, from morning to noon, the illuminance that the sun can provide gradually increases, and the maximum output voltage that the solar panel can prov...
