More specifically, this level comparison circuit comprises level comparator, and this charged battery voltage value (Vbat) outputs to the in-phase input end of this level comparator through first resistance (R1) and second resistance (R2) voltage after partial value (V0).
More specifically, the reference voltage value (Vb) of this charging voltage value (Vin) after the 3rd resistance (R3) and the 4th resistance (R4) dividing potential drop outputs to the inverting input of this level comparator.
More specifically, this indicator light is the double-colored two-way light-emitting diode of LED.
More specifically, described setting-up time is 1-5 second.
The charger that the utility model provides is when beginning to charge, and charging indicator light is lighted, and expression enters charged state, charging indicator light extinguishes subsequently, and in charging process, charging indicator light keeps extinguishing state, after charging was finished, charging indicator light was lighted, and prompting user charging is finished.The charger that the utility model provides is in the process of whole charging, indicator light is only lighted when charge beginning and charging are finished, remind the user to enter charged state and charging is finished by the light that sends of short duration different colours, saved electric energy on the one hand, avoided light pollution on the other hand.
Description of drawings
Fig. 1 is the charger circuit figure of the utility model embodiment.
Embodiment
The technical scheme that the utility model provides is: when beginning to charge, charging indicator light is lighted, and expression enters charged state, charging indicator light extinguishes subsequently, and in charging process, charging indicator light keeps extinguishing state, after charging was finished, charging indicator light was lighted, and prompting user charging is finished.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 is the charger circuit figure of the utility model embodiment, and this charger comprises charging terminal 101, touch-control delay circuit, level comparison circuit and charging indication, wherein:
The touch-control delay circuit comprises the touch-control delay switch K and the resistance R 6 of series connection, touch-control delay circuit one termination charging voltage Vin, another termination charging indication.Level comparison circuit comprises level comparator 102, resistance R 1, resistance R 2, resistance R 3, resistance R 4 and resistance R 5, charged battery voltage Vbat is through the in-phase input end of resistance R 1 and resistance R 2 voltage after partial value V0 incoming level comparators 102, charging voltage value Vin (through behind the power supply changeover device) is through the inverting input of the reference voltage value Vb incoming level comparator 102 after resistance R 3 and resistance R 4 dividing potential drops, and the output of level comparator 102 connects charging indication through resistance R 5.Charging indication comprises the double-colored two-way light-emitting diode of a LED, can send red and green light.
When rechargeable battery was put into charger, charging voltage Vin made and begins touch-control delay switch K conducting to the instantaneous charging of its electric capacity, and keeps touch-control delay switch K conducting.The double-colored two-way light-emitting diode forward conduction of the LED of charging indication, the LED lamp is lighted, send red light, indication charger operate as normal enters charged state, after several seconds, begin discharge after the electric capacity charging of touch-control delay switch K is finished, when voltage was lower than certain value, touch-control delay switch K disconnected, the double-colored two-way light-emitting diode of the LED of charging indication ends, and the LED lamp extinguishes.By the design to capacitor charge and discharge time of touch-control delay switch K, can control the time that indicator light lights is 1-5 second, in order to indication charger operate as normal, charging beginning.
In charging process, the magnitude of voltage Vbat of rechargeable battery rises gradually, magnitude of voltage V0 rises thereupon gradually, the level comparator 102 of level comparison circuit is with comparing voltage value V0 and reference voltage value Vb, when magnitude of voltage V0 less than reference voltage value Vb, level comparator 102 no-output voltages, the double-colored two-way light-emitting diode of the LED of charging indication is not luminous; When magnitude of voltage V0 more than or equal to reference voltage value Vb, that is to say, when the magnitude of voltage Vbat of rechargeable battery reached charging voltage value Vin, the expression charging was finished, level comparator 102 outputs one forward control voltage, the double-colored two-way light-emitting diode forward conduction of the LED of charging indication, the LED lamp is lighted, and sends green light, and the indication charging is finished, remind the user that charging is finished, can take battery away.After battery was taken away, LED extinguished.
As mentioned above, the charger that the utility model provides is in the process of whole charging, indicator light is only lighted when charge beginning and charging are finished, remind the user to enter charged state and charging is finished by the light that sends of short duration different colours, save electric energy on the one hand, avoided light pollution on the other hand.
