Description
Technical field
The utility model relates to a kind of battery charging circuit based on photovoltaic generation.
Background technology
The existing storage battery that utilizes solar recharging, be that solar cell is that electric energy charges to storage battery with conversion of solar energy, yet, in the practical application, have only when sunlight is enough strong, it is charge in batteries that solar cell could produce enough big voltage, and when sunlight was more weak or cloudy, solar cell was not just brought into play effect, for this reason, a kind of charging circuit that also can utilize the solar cell charging under the low light level is provided,, is very important to improve solar energy utilization rate.
Summary of the invention
In view of the deficiency of above-mentioned technology, the purpose of this utility model provides a kind of battery charging circuit based on photovoltaic generation, and it can be implemented under the more weak situation of sunlight and also can charge to storage battery, has improved solar energy utilization ratio greatly.
The utility model adopts following scheme to realize: a kind of battery charging circuit based on photovoltaic generation, comprise solar cell, and it is characterized in that: the output of described solar cell is connected with a booster circuit; The control end of described booster circuit is connected with square wave generation circuit, and output is connected with the input of storage battery; The input of described storage battery also directly is connected with the output of solar cell.
Based on above-mentioned, the utility model is when sunlight is more intense, directly charge a battery, when sunlight is more weak, pass through booster circuit, improve charging voltage, continue charging, entire circuit can improve the charge efficiency and the solar energy utilization rate of solar cell batteries according to the strong and weak charging modes of selecting automatically of sunlight.
Description of drawings
Fig. 1 is the utility model schematic block circuit diagram.
Fig. 2 is the utility model circuit connection diagram.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the utility model provides a kind of battery charging circuit based on photovoltaic generation, comprises solar cell, it is characterized in that: the output of described solar cell is connected with a booster circuit; The control end of described booster circuit is connected with square wave generation circuit, and output is connected with the input of storage battery; The input of described storage battery also directly is connected with the output of solar cell.
Specifically, see also Fig. 2, Fig. 2 is the circuit connection diagram of the utility model one examples of implementation, and as we know from the figure, the booster circuit in present embodiment is the boost booster circuit, and it is made up of an inductance, IGBT pipe and a diode.Described solar cell output is connected with storage battery through an optocoupler, and described optocoupler links to each other with the base stage of the IGBT pipe of described boost booster circuit, is used to control the switching of IGBT pipe.Like this, when sunlight was sufficient, the solar cell terminal voltage was higher, and by D1, D2 accumulators E charging, photocoupler D2 flows through electric current simultaneously, makes its transistor side be low resistive state, makes IGBT be in cut-off state, and the boost booster circuit is work not.When sunlight is more weak, the solar cell terminal voltage is lower, storage battery E voltage height, D1, D2 can't conductings, and the transistor side of photocoupler is cut-off state, at this moment, the square wave output circuit triggers the IBGT pipe by R3, makes inductance L, IBGT pipe, D3 form the boost booster circuit, the terminal voltage of solar cell is raise, and E charges to storage battery.Therefore, entire circuit can improve the charge efficiency and the solar energy utilization rate of solar cell batteries according to the strong and weak charging modes of selecting automatically of sunlight.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
