Step S1, according to the output voltage, adjusts the digital variable resistance 107.When detecting unit 105 it is defeated by what is detected Go out after voltage is transferred to the microcontroller 106, the microcontroller 106 enters to the digital variable resistance 107 according to the output voltage Row is adjusted.As the digital variable resistance 107 is connected to the charging current configuration end of the current conversion unit 104, so as to the number The change of word variable resistance 107 is directly corresponding with the charging current.Such as current conversion unit is integrated circuit BQ24075, resistance of the microcontroller 106 by the reduction digital variable resistance 107, so that the charging current increases, this fills Electric current increases, so as to the output voltage of the solar panels 101 is decreased.Wherein, this digital variable resistance 107 is predeterminable puts One initial default value, the initial default value can to should charging current a smaller value, for example the smaller value is in 10mA to 100mA Between, during so as to the subsequent adjustment digital variable resistance 107, so that the charging current gradually increases.When solar panels 101 connect When entering to the charge control module, the microcontroller 106 starts to adjust the digital variable resistance 107 from the initial default value.Separately Outward, the microcontroller 106 can be adjusted to the digital variable resistance 107 according to certain difference, i.e. the microcontroller 106 Change 107 1 fixed resistance value of digital variable resistance every time.For example the microcontroller 106 gradually increases the digital variable resistance 100 ohm of 107 resistance.Certainly the microcontroller 106 can also make the charging current (or the output voltage) and fix change with one Value is changed, so that final charging current (output voltage) is adjusted to maximum charge value (lowest critical value).

Step S2, receives the output voltage now.After the digital variable resistance 107 is adjusted by step S1, this is detectd Survey unit 105 detects output voltage now again.The microcontroller 106 receives the output voltage after adjusting again.And by now Whether the output voltage continued to adjust the foundation of the digital variable resistance 107 as next time.

Step S3, judges whether the output voltage now is equal to the lowest critical value.Judge defeated in above-mentioned steps S2 Go out whether voltage is lowest critical value.If in this step S3, if the output voltage now is not equal to the minimum critical Value, then return above-mentioned steps S1, continues to adjust the digital variable resistance 107, continues the output voltage after detecting is adjusted, until The output voltage is equal to the lowest critical value.If the output voltage now is equal to the lowest critical value, perform follow-up Step.It should be noted that as the regulation of the digital variable resistance 107 may be not necessarily continuous, thus, the output Can allow the presence of certain allowable error between voltage and lowest critical value, as long as that is, the output voltage is in the lowest critical value The output voltage can be given tacit consent in range of allowable error and is equal to the lowest critical value.The allowable error can be the output voltage and be somebody's turn to do The ratio of the difference of lowest critical value and the lowest critical value, when the allowable error is less than 5%, you can given tacit consent to the output voltage Jing is equal to the lowest critical value.Or, the allowable error can be directly also the difference between the output voltage and the lowest critical value Value, if lowest critical value is 5V, then the allowable error should be less than 0.25V.In addition, can also be further such that the output voltage It is in the second marginal value slightly larger than the lowest critical value to be charged, the purpose of do so, it is possible to decrease the charge control module Persistently operate with full load and destroy the danger of charge control module.

Step S4, maintains the output voltage in the lowest critical value, so that the charging current is entered with the maximum charge value Row charges.Through the regulation of above-mentioned steps, the microcontroller 106 passes through to adjust the digital variable resistance 107, so that this is defeated Go out voltage in lowest critical value.Then the microcontroller 106 stops adjusting the digital variable resistance 107, keeps the digital variable The resistance of resistance 107 is constant, persistently accumulator 103 is charged with maximum charge value with maintaining the charging current.By this The regulation of microcontroller 106 so that the charge control module can be according to the solar panels 101 of the different size of insertion using not Same current value is charged to accumulator 103, it is ensured that the maximum power transfer of the solar panels 101.
