The performance diagram of UI.As can be seen from Figure 5 the output voltage U of the solar panels 101 is with the characteristic of charging current I, defeated
Go out voltage U to be inversely proportional to charging current I, and the output voltage U of the solar panels 101 can subtract with the increase of charging current I
It is little.When output voltage U is reduced to lowest critical value Vmin, charging current I now is in maximum charge value Imax.And work as
When charging current I is in maximum charge value Imax, output state of the solar panels 101 in peak power.It is special using this

Device 106 adjusts the flow chart of the charging current, and in combination with shown in Fig. 4, the microcontroller 106 adjusts the process of the charging current
Including:
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 voltage to be transferred to after the microcontroller 106, the microcontroller 106 enters the digital variable resistance 107 according to the output voltage
Row is adjusted.Because 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, the resistance that microcontroller 106 passes through the reduction digital variable resistance 107, so that charging current increase, 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 according to certain difference to the digital variable resistance 107, i.e. the microcontroller 106
Change the fixed resistance value of digital variable resistance 107 1 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 the final charging current (output voltage) is adjusted to maximum charge value (lowest critical value).
Step S2, receives the output voltage now.Adjusted after the digital variable resistance 107 by step S1, this is detectd
Survey unit 105 detects again output voltage now.The microcontroller 106 receives again the output voltage after adjusting.And by now
Whether the output voltage continues the foundation for adjusting 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 to detect the output voltage after adjusting, 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 because 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 difference of lowest critical value and the ratio of 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 also can be directly 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 and is charged slightly larger than the second marginal value of the lowest critical value, 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 has caused this defeated by adjusting the digital variable resistance 107
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, with maintaining the charging current persistently accumulator 103 is charged with maximum charge value.By this
The regulation of microcontroller 106 so that the charge control module can be adopted not according to the solar panels 101 of the different size of insertion
Same current value is charged to accumulator 103, it is ensured that the maximum power transfer of the solar panels 101.
It should be noted that one of ordinary skill in the art will appreciate that during the regulation of above-mentioned microcontroller 106
All or part of step can instruct related hardware to complete by program, and described program can be stored in computer-readable storage medium
In matter, such as read only memory, disk or CD.Alternatively, above-mentioned all or part of step can also use one or more
