10This 10 reference voltages are provided respectively, and are added to IC
1-IC
10Negative input end, battery voltage signal is added to IC
1-IC
10Positive input terminal, like this when battery voltage signal during greater than the reference voltage of respective volume, this comparator output high level, and directly drive the LED of correspondence
1-LED
10, these 10 green LED light-emitting diodes show the battery capacity of 10%-100% respectively like this, and battery capacity is sufficient more, and the LED that lights is many more.Voltage comparator ic
11, be used to detect the floating charge overvoltage of battery, when because charger fault when making the battery float overvoltage, IC
11Input high level, and be added to fault trigger IC
12Set end S, IC
12Be set, Q exports high level, passes through V
3Drive red light emitting diodes LED
11Make the overvoltage fault and show, pass through V

1Output control external circuit make to cut off the charger power supply, connect auto-activation operations such as discharge loop.Along with the carrying out of activation discharge, cell voltage reduces gradually, when cell voltage is lower than 50% battery capacity, and 50% battery capacity detection comparator IC
15The output low voltage level is through NAND gate IC
16After be added to discharge trigger IC
15Reset terminal R and timer IC
14Removing end R, activation discharge finishes like this, the timer reclocking, the discharge trigger reset, the Q output low level, the discharge relay discharges.
Therefore because the reset operation of discharge timer and discharge trigger is by battery capacity 50% signal controlling, as long as depth of discharge reaches this value, then thinking has discharge once, no matter and discharge is caused by timer, still interrupt causing by civil power.If the discharge that civil power interrupts causing does not reach this degree of depth, then timer remains valid and continues.Can get rid of like this because moment, civil power interrupts and timing circuit is impacted in short-term.
Timer also provides the flashing light of frequency 1-2 time/second, this flashing light control triode V
1Do the flash of light driving that each capacity shows LED, triode V
2Do normal bright driving.V
2Be by discharge trigger IC
15Discharge signal through inverter ic
17Control, so only when activation is discharged, V
2End LED
1-LED
10Do flicker and show that indication circuit is in the auto-activation state, and in normal condition, and the battery discharge status of civil power when interrupting, IC
15Control signal output, V
2Conducting, at this moment LED
1-LED
10Be in normal bright state.For fault LED
11, owing to be subjected to flashing light through inverter ic
18Directly control as long as it is lighted, promptly is in blink states.
Timer also provides about 8-16 of cycle the reset signal of second, is added to the reset terminal (R end) of fault trigger by differential circuit, if reset IC
12Back IC
11The overvoltage blackout, IC then
12Be reset J
2Discharge, it is normal that circuit recovers, if the overvoltage signal still exists, and then heavy again above-mentioned protection action.
The utility model can directly show battery meter; states such as floating charge overvoltage and auto-activation operation; the needed timing of automation, outage, battery discharge can be provided; discharge off recovers the normal sequence of operations that waits; can the discharge that lead-acid battery fills be monitored and protect; can prolong the useful life of battery effectively, and low cost of manufacture.
Fig. 1 is the schematic appearance of a kind of embodiment of the present utility model, and Fig. 2 is that battery shows and the auto-activation circuit theory diagrams automatically.The utility model is described in further detail below in conjunction with accompanying drawing.
