Abstract
The utility model discloses an automobile storage battery monitor which comprises a stabilivolt, a first audion, a second audion, a first transistor, a second transistor, a third transistor, a first light emitting diode, a second light emitting diode and a potentiometer. According to the automobile storage battery monitor, the first light emitting diode is in series connection with the first transistor so that only the first light emitting diode shines when input voltage ranges from 3 volts to 12 volts; the green second light emitting diode and the stabilivolt are further arranged so that only the second light emitting diode shines and the first light emitting diode does not shine when the voltage of a storage battery is over 12 volts; and when the voltage is over 13.5 volts, both the first light emitting diode and the second light emitting diode shine to indicate that an automobile is in a normal charging state. The automobile storage battery monitor can be conveniently used to monitor not only the voltage of the automobile storage battery, but also working conditions of an automobile charging circuit, facilitates reinforcement of maintenance of the battery at any time, prolongs service life of the battery, and avoids breakdowns, caused by battery failure, of the automobile on roads.
Description
Technical field
The utility model relates to a kind of monitor for storage battery, relates in particular to a kind of automobile storage battery monitor.
Background technology
Along with popularizing of automobile, increasing family has had the automobile of oneself, and the storage battery in the automobile has the life-span, if do not note at ordinary times the maintenance of battery, battery will lose efficacy with individual 1 year, and automobile causes because of the inefficacy of storage battery and casts anchor on the way, thereby makes troubles.
Summary of the invention
The purpose of this utility model provides a kind of automobile storage battery monitor with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The utility model comprises stabilivolt, the first triode, the second triode, the first resistance, the second resistance, the 3rd resistance, the first light emitting diode, the second light emitting diode and potentiometer, the first end of described the first resistance is connected with storage battery with the negative pole of described stabilivolt simultaneously and is connected, described stabilivolt anodal simultaneously with the first end of the described potentiometer of first end of described the second resistance be connected the first end of the 3rd resistance and be connected, the second end of described the 3rd resistance is connected with the positive pole of described the second light emitting diode, the negative pole while of described the second light emitting diode and the second end of described potentiometer, the emitter of described the second triode, the emitter of described the first triode, the negative pole of described the first light emitting diode be connected the negative pole of storage battery and connect, the sliding end of described potentiometer is connected with the base stage of described the second triode, the collector of described the second triode with simultaneously with the second end of described the second resistance be connected the base stage of the first triode and be connected, the collector while of described the first triode and the positive pole of described the first light emitting diode be connected the second end of the first resistance and be connected.
The beneficial effects of the utility model are:
The utility model not only can monitor the voltage of automobile storage battery easily, can also monitor the working condition of vehicle charging circuit, is convenient to strengthen at any time the maintenance to battery, extends the life of a cell, and avoids automobile to cause the situation of casting anchor on the way because storage battery loses efficacy.
Description of drawings
Accompanying drawing is circuit structure schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings: the utility model comprises stabilivolt DW, the first triode VT1, the second triode VT2, the first resistance R 1, the second resistance R 2, the 3rd resistance R 3, the first LED 1, the second LED 2 and potentiometer RP, the first end of the first resistance R 1 is connected with storage battery with the negative pole of stabilivolt DW simultaneously and is connected, the anodal while of stabilivolt DW is connected with the first end of the first end potentiometer RP of the second resistance R 2 and the first end of the 3rd resistance R 3, the second end of the 3rd resistance R 3 is connected with the positive pole of the second LED 2, the negative pole while of the second LED 2 and the second end of potentiometer RP, the emitter of the second triode VT2, the emitter of the first triode VT1, the negative pole of the first LED 1 is connected negative pole and is connected with storage battery, the sliding end of potentiometer RP is connected with the base stage of the second triode VT3, the collector of the second triode VT2 with simultaneously with the second end of the second resistance R 2 be connected the base stage of triode VT1 and be connected, the collector while of the first triode VT1 and the positive pole of the first LED 1 be connected the second end of resistance R 1 and be connected.
As shown in drawings: light emitting diode must be gone here and there a current-limiting resistance in circuit generally speaking, and the size of resistance decides according to the working current of light emitting diode.The first LED 1 of the present utility model is selected the light emitting diode of red Φ 3 and the first resistance R 1 that resistance is 1k Ω, makes the working current of input voltage first LED 1 when 3-12V changes be about 1～10mA; Increase the second LED 2 of a green Φ 3 again, also be connected in series simultaneously the stabilivolt DW of a 10V in its front, the second LED 2 just can be bright when only having like this input voltage to surpass 12V.The second resistance R 2 also is a current-limiting resistance, for no other reason than that stabilivolt DW can have the voltage drop of 10V, so the resistance of the second resistance R 2 only has 100 Ω, only have the second LED 2 bright when making battery voltage surpass 12V, and the first LED 1 does not work, be provided with the first triode VT1 and the 3rd resistance R 3 in the circuit, like this when battery voltage surpasses 12V, the 3rd resistance R 3 makes the first triode VT1 conducting, the first LED 1 two ends can not get due operating voltage (generally about 1.8～2V), so the first LED 1 does not work, if input voltage continues to raise, when surpassing 13.5V, show that automobile current generator is working properly, charging to storage battery, for this state is indicated, and no longer increasing the number of light emitting diode, circuit is provided with the second triode VT2 and potentiometer RP.The second triode VT2 conducting when making voltage surpass 13.5v forces the first triode VT1 can not conducting and end, and such the first LED 1 and the second LED 2 are all bright.The expression automobile is in charged state.
When the utility model uses, only need be connected to it on the plug of automobile cigarette lighter, then directly be inserted on the socket of automobile cigarette lighter and just can have monitored automobile storage battery.
