Abstract
The utility model discloses a charger for rechargeable cells and general alkali dry cells. An operational amplifier in a CMOS circuit is replaced by a comparison amplifier. The output terminal controls a current amplifier. Homophase terminals are respectively connected with a standard comparison voltage (1. 25V or 1. 57V) through a single-pole double-throw switch K. The homophase terminals can respectively charge the rechargeable cells and the general alkali dry cells. Reversed phase terminals are connected with the positive terminal of a cell and the output terminal of the current amplifier. When the cell voltage is charged to a rated value, and the voltages of the homophase terminals and the reversed phase terminals are equal; the indicator is off, the current amplifier stops, and the charging stops.
Description
Technical field
The utility model relates to a kind of charging device that rechargeable battery and common alkali dry cell are charged, and belongs to the charging technique field.
Background technology
Existing charging technique can only charge to rechargeable battery, for example nickel-cadmium cell, Ni-MH battery, lithium battery is charged.Owing to there be not a kind of can a charging to rechargeable battery, the device that can charge to general dry battery again, therefore, the discarded dry cell in the society is more and more, and more and more environment has been caused harm, has formed unavoidable social concern.
Summary of the invention
The purpose of this utility model, be propose a kind of can be to rechargeable battery, the environmental protection charging device that also can charge, use repeatedly to discarded alkaline dry battery.
The technical solution of the utility model is achieved like this, and utilizes the operational amplifier in the cmos circuit, with anti-phase, in-phase input end, is connected into comparison amplifier, utilizes a single-pole double-throw switch (SPDT), with the normal voltage of two-way precision, introduces in-phase input end.Stir double-point double-throw switch, can cut the normal voltage of changing in-phase input end, or be 1.25V, or be 1.57V.1.25V charge for nickel-cadmium cell, Ni-MH battery, lithium battery, the 1.57V normal voltage 1.5V of dry cell (approximately greater than) is for common alkaline dry battery charge.Inverting input links with the anode that is recharged the pond, and communicate with the output of current amplifier, the control end of current amplifier connects with the output of operational amplifier, since the terminal voltage this moment that is recharged battery than in-phase voltage the end of than, comparison amplifier work, the output output high level of operational amplifier, current amplifier work is to being recharged the pond charging.Along with the battery charge trend is saturated, the inverting input voltage of operational amplifier is also along with rising, and when inverting input voltage equated with the voltage of in-phase input end, operational amplifier quit work, and current amplifier quits work immediately, and charging stops.The beneficial effects of the utility model are, the charging current of this method is that the rising with the terminal voltage of rechargeable battery descends, and can not overcharge, and battery can not generate heat in the charging process.Therefore alkaline dry battery can be reused, and has improved the utilance of resource, the more important thing is the pollution that has alleviated environment.
Description of drawings
Accompanying drawing 1 is a fundamental diagram of the present utility model.
Accompanying drawing 2 is the embodiment that adopt the device of 4 operational amplifiers.
In the accompanying drawing 1, adjust resistance R 1, R2, R3, R4, R5, R6, current-limiting resistance R7, R8, R9, voltage stabilizing didoe D1, D2, D3, light-emitting diode D4.Potentiometer VR1, VR2, constant current source of stable pressure IC2, IC3, electric capacity of voltage regulation C1, operational amplifier IC1, weakening capacitor C 2, triode Q, No. 5 batteries (AA) E1, No. 7 batteries (AAA) E2, single-pole double-throw switch (SPDT) K.
In the accompanying drawing 2, anode 1, battery 2 (AA or AAA), battery cathode 3, single-pole double-throw switch (SPDT) 4 (being the single-pole double-throw switch (SPDT) K in the accompanying drawing 1), wiring board 5, light-emitting diode 6 (being the D4 in the accompanying drawing 1).
Embodiment
Accompanying drawing 1, it is the winding diagram that a batteries is charged, among the figure, the output of operational amplifier IC1 " A " point is connected, also passes through current-limiting resistance R7 with capacitor C 2 with luminous tube D4, being connected to current amplifier is the base stage of triode Q, luminous tube D4 is on the one hand as working station indicator, on the other hand in working order the time, provide constant current to current amplifier, within the specific limits with the control output current.Electricity capacitor C 2 is mainly done weakening at this, in case circuit vibrates; The in-phase input end of operational amplifier IC1 and single-pole double-throw switch (SPDT) K, capacitor C 1 are connected, and when K being pulled to the upper end, being K when being connected with K1, the in-phase input end of IC1 is controlled on the 1.25V, and circuit charges to rechargeable battery.When K being toggled it to the lower end, being K when being connected with K2, the in-phase input end of IC1 is controlled on the 1.57V, circuit alcaliotropism dry battery charge.Transfer to the control voltage principle of K1 and K2, components and parts and wiring are just the same, and different is to realize by adjusting potentiometer VR1, VR2 respectively.So that the 1.57V normal voltage to be provided is example.K2 point and diode D2, adjust resistance R 5 and be connected, R5 again be connected with R4 that power vd D1 communicates and be connected and electric current is provided with the negative terminal of constant current source of stable pressure IC3.Negative terminal and the R6 of diode D2 join, and R6 is connected with potentiometer VR2 again.Adjusting VR2 just can make voltage control that K2 orders at 1.57V.Because the effect of constant current source of stable pressure IC3 when fluctuation takes place external power, by resistance R 4, will be stablized constant by the K2 point voltage.The emitter of the other end of inverting input and weakening capacitor C 2, current-limiting resistance R8, triode Q, "+" of No. 5 battery E1 end are connected at the B point.The collector electrode of triode Q is connected with power vd D2 with current-limiting resistance R9 with diode D3.No. 7 batteries (AAA) E2 is connected with current-limiting resistance R8, to limit the charging current of No. 7 batteries.
Embodiment
Accompanying drawing 2 is to use 4 operational amplifiers, what make (can be No. 5 to the charging of four batteries respectively, it also can be No. 7, perhaps both palm off as) the embodiment of amplifier, be charged as example with alkaline battery: each road amplifier only charges to a batteries, after the battery with undertension 1.5V inserts circuit, again K switch is stirred downwards, K is connected with K2.This moment, output " A " some current potential was near VDD1 owing to put current potential in " K " at the bottom of " B " some current potential, and luminous tube D4 is luminous, and triode Q work is to battery charge.Along with " B " some current potential raises gradually, the electric current that triode Q provides is fewer and feweri, and when 2 current potentials of " B " " K " equated, " A " point was descended close with " K " by high potential, and luminous tube D4 goes out, and triode Q quits work, and this road charging is finished.Be not quite similar owing to be recharged initial voltage, the structure of battery, so the charging interval also is not quite similar.The time that corresponding luminous tube extinguishes is also inequality.Therefore the integrated circuit of a slice 4 operational amplifiers can fill 4 batteries simultaneously, and the integrated circuit of 2 operational amplifiers can only charge to two batteries.In the charging process, each road mutually noninterfere.
