Brief description of the drawings
Fig. 1 is the circuit diagram of intelligent charge control circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of intelligent charge control circuit, including resistance R1, triode
Q1, LED, potentiometer RP1 and one-way SCR VS, described resistance R1 one end connect resistance R4, resistance R3 respectively
With triode Q1 colelctor electrodes, the resistance R4 other ends connect power supply VCC, triode Q3 emitter stages, resistance R2 and resistance R6 respectively, electricity
R2 other end connecting triode Q4 colelctor electrodes are hindered, triode Q4 base stages connect the resistance R6 other ends respectively and ground connection diode D1 is born
Pole, triode Q4 emitter stages difference connecting luminous diode LED negative poles, triode Q2 colelctor electrodes and battery E positive poles, luminous two
Pole pipe LED positive poles pass through resistance R5 connecting triode Q3 colelctor electrodes, the triode Q3 base stages connection resistance R3 other ends, triode Q1
