Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of full-automatic intelligent charger, including time base chip U1, LED 1, resistance R1, diode D1 and potentiometer RP1, described resistance R1 one end connects power supply VCC respectively, resistance R3, time base chip U1 pin 4, time base chip U1 pin 8 and diode D2 positive pole, diode D2 negative pole connecting triode VT1 colelctor electrode, the resistance R1 other end connects resistance R2 respectively, LED 1 negative pole and LED 2 positive pole, LED 1 positive pole is connecting luminous diode LED2 negative pole respectively, time base chip U1 pin 3 and resistance R4, the resistance R4 other end connects diode D3 positive pole, diode D3 negative pole is connecting triode VT1 base stage and accumulator E positive pole respectively, accumulator E negative pole connects resistance R6 respectively, time base chip U1 pin 1, diode D1 positive pole and the resistance R2 other end ground connection, diode D1 negative pole connects the resistance R3 other end and Shi Ji chip U1 pin 5 respectively, the described resistance R6 other end connects potentiometer RP2 one end, the potentiometer RP2 other end connects potentiometer RP1 one end respectively, potentiometer RP1 slide plate and Shi Ji chip U1 pin 6, the potentiometer RP1 other end passes through resistance R5 connecting triode VT1 emitter stage, base chip U1 pin 2 when potentiometer RP2 slide plate connects, time described, base chip U1 adopts NE555.
Operation principle of the present utility model is: refer to Fig. 1, NE555 is connected into window comparator by this utility model, its reference voltage is set by Zener diode D1, if the 2 foot current potentials of U1 are lower than reference voltage half, the then 3 foot output high level of U1, U1 monitors battery tension situation by VT1, when accumulator E brownout, the voltage of 2 feet of U1 is lower than lower window edge value, 3 feet of U1 are exported high level and are charged to accumulator E by R4 and D3, when cell voltage rises to the RP1 higher limit set (magnitude of voltage that accumulator is sufficient), U1 overturns, the 3 foot output low levels of U1, thus stopping charging. but U1 continues to monitoring accumulator E voltage, when accumulator E voltage reduces, circuit charges to battery again, and LED 1 and LED2 indicate the duty of charger, and during charging, LED 1 is bright, and time static, LED 2 is bright.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.
