Brief description
Fig. 1 is the circuit diagram of solar energy automatic charger.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, a kind of solar energy automatic charger, including solar panels T, resistance R4, diode D1 and relay
One end of K, described solar panels T connects the contact K-1 of relay K, and the other end of the contact K-1 of relay K connects potentiometer
One fixing end of RP1 and the drain electrode of metal-oxide-semiconductor Q1, another fixing end of potentiometer RP1 connects resistance R1, electric capacity C1 and three ends
