The utility model discloses the voltage drop of group battery E to the definite value after, automatic switch -over charging circuit, E charges for the group battery, makes the circuit can keep at operating condition always, prevents because group battery E does not have the electricity, and makes load RL stop work, be applicable to can not intermittent type work into some the device power supply.

Description

Automatically the control circuit of charged state is proceeded to after a kind of battery discharge

Technical field

This utility model is related to a kind of control circuit, and the control of charged state is proceeded to automatically after specifically a kind of battery discharge Circuit.

Background technology

Chemical energy is converted into the device of electric energy chemical cell, commonly abbreviated as battery, after electric discharge, can use the side charged Formula makes internal active substance regeneration, is chemical energy electrical power storage, needs chemical energy is converted to electric energy again during electric discharge, by this Class battery is referred to as accumulator, also referred to as secondary cell.

Accumulator as it is a kind of can be with the power store of Reusability, widely, but accumulator makes for application With the life-span with it whether Jing often excessively electric discharge has a very big relation, Jing normal overdischarge, can high degree shorten life-span of accumulator, Meanwhile, some devices need to work always, once set of cells E electric energy exhausts, load cannot obtain power supply and power, and may give people Bring very big economic loss.

Utility model content

The purpose of this utility model be a kind of battery discharge is provided after proceed to automatically the control circuit of charged state, to solve The problem proposed in certainly above-mentioned background technology.

For achieving the above object, this utility model provides following technical scheme：

Automatically the control circuit of charged state, including relay J, switch S, resistance R1, electricity are proceeded to after a kind of battery discharge Hold C1, audion VT1, potentiometer RP1 and diode D1, described switch S one end connects electrolytic grounding cell group E positive pole and relay respectively Device J contact J-1, relay J contact J-1 other end connection charging circuits, the switch S other ends connect resistance R1, electric capacity C1 respectively With chip U1 inputs, the resistance R1 other ends connection earthing potential device RP1, potentiometer RP1 slide plate connecting triode VT1 base stages, Audion VT1 grounded emitters, audion VT1 colelctor electrode connecting triode VT2 base stages, audion VT2 colelctor electrodes connect two poles Pipe D1 positive poles, diode D1 negative poles connection grounding relay J coils, audion VT2 emitter stages connect electric capacity C2, chip U1 respectively Outfan and load RL, load RL other end connection ground connection LED positive pole, the electric capacity C2 other ends connect electric capacity respectively C1 and chip U1 earth terminals are simultaneously grounded.

As further program of the utility model：The chip U1 adopts LM7812.

As this utility model further scheme：The relay J contacts J-1 is normally-closed contact.

Compared with prior art, the beneficial effects of the utility model are：This utility model is dropped to necessarily in set of cells E voltage After value, automatic switchover charging circuit is that set of cells E charges, and enables the circuitry to be always maintained in working order, preventing because battery Group E does not have electricity, and makes load RL quit work, it is adaptable to is unable to intermittently used device for some and powers.

Description of the drawings

Fig. 1 be battery discharge after proceed to automatically charged state control circuit circuit diagram.

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 describe, it is clear that described embodiment is only this utility model a part of embodiment, 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 creative work is made The every other embodiment for being obtained, belongs to the scope of this utility model protection.

Fig. 1 is referred to, the control electricity of charged state in this utility model embodiment, after a kind of battery discharge, is proceeded to automatically Road, including relay J, switch S, resistance R1, electric capacity C1, audion VT1, potentiometer RP1 and diode D1, the switch S mono- End connects electrolytic grounding cell group E positive pole and relay J contact J-1, relay J contact J-1 other end connection charging circuits respectively, opens Close the S other ends and connect resistance R1, electric capacity C1 and chip U1 inputs, resistance R1 other ends connection earthing potential device RP1, electricity respectively Position device RP1 slide plate connecting triode VT1 base stages, audion VT1 grounded emitters, audion VT1 colelctor electrode connecting triode VT2 Base stage, audion VT2 colelctor electrodes connection diode D1 positive poles, diode D1 negative poles connection grounding relay J coils, audion VT2 emitter stages connect electric capacity C2, chip U1 outfans and load RL, load RL other end connection ground connection light emitting diode respectively LED positive poles, the electric capacity C2 other ends connect electric capacity C1 and chip U1 earth terminals respectively and are grounded；The chip U1 adopts LM7812； The relay J contacts J-1 is normally-closed contact.

Operation principle of the present utility model is：Fig. 1 is referred to, set of cells E is Full Charge Capacity battery, after Push switch S, due to Now set of cells E terminal voltage is higher, so VT1 base stages, now VT1 base potentials are injected Jing after resistance R1, potentiometer RP1 partial pressures Higher, VT1 conductings, VT2 are also switched on, and set of cells E is discharged to loading RL after chip U1 voltage stabilizings, while display lamp luminous two Pole pipe LED is shinny, now relay J adhesives, and contact J-1 disconnects, and cuts off charging of the charging circuit to set of cells E；When set of cells E Voltage drop to be insufficient to allow audion VT1 turn on when, relay J dead electricity, its contact J-1 closure, charging circuit access circuit In give set of cells E charge.

In sum, after set of cells E voltage drops to certain value, automatic switchover charging circuit is battery to this utility model Group E charges, and enables the circuitry to be always maintained in working order, preventing because set of cells E there is not electricity, and makes load RL quit work, It is suitable for some and is unable to intermittently used device powering.
