Background technology
Accumulator is energy storage electronic equipment common in daily life, it is known that, accumulator needs to be charged after being finished electricity, the most most charger is all that constant current flings type, the voltage constant of its charging, will not change along with the process of accumulator charging, more cannot realize being automatically stopped charging, therefore easily cause accumulator crosses punching.The most intelligent, safe charging modes, is the emphasis studied of people.
Existing a lot of charging intelligent controller all uses relay as the controller of charging automatic stop, use relay can increase the caloric value of charger, need to increase fin, the volume causing charger is bigger, and relay is easily subject to electromagnetic interference, cause controlling insensitive, additionally for existing accumulator, it is found that after charging complete, continue battery is carried out low current charge, the life-span postponing battery is had very great help, this utility model provides a kind of fully-automatic intelligent battery charger, ensure that accumulator can also carry out trickle charge by small area analysis after fully charging, stability is high, volume is little, low cost, applied widely.
Utility model content
The purpose of this utility model is to provide a kind of fully-automatic intelligent battery charger, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
nullA kind of fully-automatic intelligent battery charger，Including three terminal regulator U1、Audion VT1、Electric capacity C1、Accumulator E、One-way SCR VS and audion VT2，Described three terminal regulator U1 input connects power supply VCC respectively、Electric capacity C1、Resistance R2 and resistance R3，Three terminal regulator U1 outfan connects ground capacity C2 and audion VT1 colelctor electrode respectively，Audion VT1 emitter stage connects resistance R1，The resistance R1 other end connects the electric capacity C1 other end respectively、The resistance R2 other end、Audion VT2 base stage、The A pole of one-way SCR VS、Potentiometer RP1 one end、Accumulator E positive pole、LED 2 negative pole and resistance R4，Audion VT2 emitter stage connects the resistance R3 other end and audion VT1 base stage respectively，The resistance R4 other end connects electric capacity C3 and audion VT2 colelctor electrode respectively，Electric capacity C3 other end connecting luminous diode LED1 negative pole respectively、The potentiometer RP1 other end and accumulator E negative pole ground connection，LED 1 positive pole connects the K pole of one-way SCR VS，The G pole of one-way SCR VS connects potentiometer RP1 slide plate.
As this utility model further scheme: described three terminal regulator uses 7809.
Compared with prior art, the beneficial effects of the utility model are: this utility model provides a kind of fully-automatic intelligent battery charger, it is ensured that accumulator can also carry out trickle charge by small area analysis after fully charging, stability is high, volume is little, low cost, applied widely.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of fully-automatic intelligent battery charger.
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 are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，In this utility model embodiment，A kind of fully-automatic intelligent battery charger，Including three terminal regulator U1、Audion VT1、Electric capacity C1、Accumulator E、One-way SCR VS and audion VT2，Described three terminal regulator U1 input connects power supply VCC respectively、Electric capacity C1、Resistance R2 and resistance R3，Three terminal regulator U1 outfan connects ground capacity C2 and audion VT1 colelctor electrode respectively，Audion VT1 emitter stage connects resistance R1，The resistance R1 other end connects the electric capacity C1 other end respectively、The resistance R2 other end、Audion VT2 base stage、The A pole of one-way SCR VS、Potentiometer RP1 one end、Accumulator E positive pole、LED 2 negative pole and resistance R4，Audion VT2 emitter stage connects the resistance R3 other end and audion VT1 base stage respectively，The resistance R4 other end connects electric capacity C3 and audion VT2 colelctor electrode respectively，Electric capacity C3 other end connecting luminous diode LED1 negative pole respectively、The potentiometer RP1 other end and accumulator E negative pole ground connection，LED 1 positive pole connects the K pole of one-way SCR VS，The G pole of one-way SCR VS connects potentiometer RP1 slide plate；Described three terminal regulator uses 7809.
Operation principle of the present utility model is: refer to Fig. 1, LED2 is charging instruction, LED1 is charging termination instruction, live part uses three terminal regulator U1 to form constant current source charging circuit, control part and use one-way SCR VS, when accumulator E full charge, the voltage at accumulator E two ends rises to a fixed value, cause VS to turn on and make LED1 luminous, and VT2 saturation conduction therewith, VT1 is caused to end without base bias current, this is the quiescent current of the charging current only remaining three terminal regulator U1 flowing through LED2 and the discharge current of electric capacity C3 of accumulator E, both electric currents are small area analysis, now for trickle charge state, ensure that accumulator E will not be overcharged.
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 in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of 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 fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
