The low advantage with cost.
Brief description of the drawings
Fig. 1 is the circuit diagram of battery energy-saving charging circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, 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, belongs to the scope of the utility model protection.
Referring to Fig. 1, a kind of safe and power saving battery charger, including resistance R1, diode D1, three end adjustable references
Source P and triode V2, the resistance R1 one end connecting triode V1 emitter stage and power supply VCC, the resistance R1 other end connect
Connecting resistance R2 and three end adjustable reference source P negative electrode, the resistance R1 other end connect resistance R3 and triode V2 base stage, three poles
Pipe V2 emitter stage connects the resistance R3 other end, resistance R5, three end adjustable reference source P anode and battery E negative pole, three
Pole pipe V1 base stage connection resistance R7, resistance the R7 other end connection diode D1 anode, diode D1 negative electrode connection three
Pole pipe V2 colelctor electrode, triode V1 colelctor electrode connection resistance R6, resistance R6 other end connection resistance R4's and battery E
Positive pole, the resistance R4 other end connection resistance R5 other end and three end adjustable reference source P reference pole.
Diode D1 is light emitting diode.
Operation principle of the present utility model is：Resistance R1, resistance R2, resistance R3 composition input partial pressure nets in circuit
Network, resistance R4, resistance R5 composition output end potential-divider network, by controlling three end adjustable reference source P, triode V1 and triode V2
Working condition so as to reach intelligent charge control purpose.When starting to charge up, E voltage is relatively low, thus by resistance R4 and
Undertension after resistance R5 partial pressures is to trigger three end adjustable reference source P, and P is not turned on, triode V2 conductings, now triode V1
Turn-on condition is met, VCC is charged by resistance R6 to battery E, and now light emitting diode D1 is lighted, triode V1 and triode
V2 constitutes Voltage stabilizing module, with the progress of charging, and E voltage is raised, and resistance R4 and R5 partial pressure are also raised, after E is full of, P
Reference pole tension reach its conducting voltage, P conductings so that short circuit V2 trigger voltage, V2 ends, triode V1 is also switched off,
Charge circuit is disconnected, the purpose of charge protection is reached, light emitting diode D1 extinguishes.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
