Accompanying drawing explanation
Fig. 1 is the circuit diagram of solar charger.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, in the utility model embodiment, a kind of solar charger, comprises solar panels T, storage battery E and diode D1, one end of described solar panels T connects the anode of diode D1, the negative electrode of diode D1 connects the contact J-1 of relay J, a stiff end of potentiometer RP1, a stiff end of potentiometer RP2 and the pin 1 of chip IC 1, the other end of the contact J-1 of relay J connects the positive pole of storage battery E, the other end of solar panels T connects electric capacity C1, electric capacity C4, another stiff end of potentiometer RP1, another stiff end of potentiometer RP2, the negative pole of storage battery E, the anode of diode D2, the pin 1 of relay J and chip IC 2, the sliding end of potentiometer RP1 connects the pin 6 of chip IC 2, the sliding end of potentiometer RP2 connects the pin 2 of chip IC 2 and the other end of electric capacity C1, the pin 2 of chip IC 1 connects electric capacity C2 and ground connection, the pin 3 contact resistance R1 of chip IC 1, the pin 8 of electric capacity C3 and chip IC 2, the other end of resistance R1 connects the other end of electric capacity C2 and the pin 4 of chip IC 2, the other end ground connection of electric capacity C3, the pin 5 of chip IC 2 connects the other end of electric capacity C4, the pin 3 of chip IC 2 connects the other end of relay J and the negative electrode of diode D2, described chip IC 1 is 7809 three terminal regulators, chip IC 2 is 555 timers.
Relay J is normally opened contact relay.
Operation principle of the present utility model is: solar panels T completes opto-electronic conversion and electric energy is transferred to charging control circuit by non-return diode D1, and charging control circuit is made up of sample circuit, flip-flop circuit and relay etc.Wherein sample circuit is divided into upper and lower bound sample circuit.The upper limit sample circuit be made up of potentiometer RP1 connects 6 pin by chip IC 2 bistable circuit, and the lower limit sample circuit be made up of potentiometer RP2 connects trigger end 2 pin of IC2.When battery tension makes the set voltage of 2 pin current potentials lower than chip IC 2, there is set in chip IC 2, the high level that its 3 pin exports makes J adhesive, and contact J-1 connects, and storage battery E starts to charge.When storage battery E voltage is charged to enough high, when making the resetting voltage of the 6 pin current potentials of IC2 higher than 555,555 reset, and the low level that its 3 pin exports makes relay J discharge, and contact J-1 disconnects, and charge circuit stopping is charged, thus effectively avoids storage battery E by overcharge.
