Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is circuit diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of full automatic stop charger has a charging panel, and the output of charging panel connects a current detection circuit, and current detection circuit connects a control relay J1.Current detection circuit comprises that one is connected on the current relay J2 of charging panel positive output end, and the normally opened contact J2-1 of current relay J2 is connected on the negative output terminal of charging panel; The two ends of a control relay J1 one-way SCR VS1 in parallel, the control utmost point of one-way SCR VS1 connects the anode of a voltage-stabiliser tube VD4, the negative electrode of voltage-stabiliser tube VD4 is connected with the normally opened contact J2-1 of current relay J2, and a charging capacitor C1 connects between the anode of the negative output terminal of charging panel and voltage-stabiliser tube VD4; Between control relay J1 and current relay J2, be in series with the normally opened contact J1-2 of diode VD2, resistance R 5, button AN and control relay J1, the negative electrode of diode VD2 is connected with control relay J1 by resistance R 5, the anode of diode VD2 is connected with normally opened contact J1-2 one end by button AN, and the normally opened contact J1-2 other end is connected with current relay J2; Utilize diode and button AN to realize startup and the reversed polarity blocking function of charging circuit.The normally opened contact J1-1 of the input series connection control relay J1 of charging panel can realize that power supply disconnects.Charging panel is switch power supply type voltage stabilization and current stabilization charging panel, and is multiplex in the small-sized electric tricycle.
Between the negative output terminal of normally opened contact J1-2 and charging panel
Series connectionOne polarity warning circuit.The polarity warning circuit comprises resistance R 6, voltage-stabiliser tube VD5, rectifier diode VD6 and buzzer BL; One end of resistance R 6 is connected with normally opened contact J1-2, the anodic bonding of the other end and voltage-stabiliser tube VD5, and the negative electrode of voltage-stabiliser tube VD5 is connected with the negative electrode of rectifier diode VD6, and the anode of rectifier diode VD6 is connected with the negative output terminal of charging panel; Buzzer BL is connected in parallel on the two ends of voltage-stabiliser tube VD5.
A normally opened contact J1-3 in the two ends of normally opened contact J1-2 Parallel Control relay J 1 increases its reliability.
Utilize the element fundamental characteristics, the accumulator polarity reversal connection warning locking of implement device.Control relay is designed to the correct polarity starting, and the inoperative circuit of mistake polarity constitutes delay releasing circuit, constitutes current detecting Control pattern.Under normal charge mode, charging current is little below setting value [general setting value be 0.01C(A)], and such as 100 ampere-hour storage batterys, under constant voltage current-limiting charge pattern, electric current is little below 1 peace, thinks that namely storage battery is sufficient.Utilize this characteristic in the battery charging process, the check charging current can disconnect charge power supply and charge circuit less than this value, realizes saving electric energy and exempting to guard target.
Correct storage battery and the power supply connected, power supply indication when red, point touches the button AN once, control relay J1 moves adhesive, and open charge power supply and battery charging circuit, ammeter have larger and suitable charging current indication, charging indication when red, the expression charger is working properly.Connect instead such as accumulator polarity, buzzer namely sends " ticking " chimes of doom, and the expression accumulator polarity connects instead, should correct, as not correcting, by charging starting button, then not adhesive of control relay J1, inoperative charging circuit.Such as the storage battery full charge, charging current is little below setting value, and current detection circuit will drive control relay J1 and delay time and return deenergization and charge in batteries loop 5 seconds.Connect correctly such as accumulator polarity, press starting button AN, control relay J1 adhesive and charge power supply and charge circuit and access failure power supply or power supply no-voltage, then install time-delay deenergization in 5 second and charge circuit, do not allow charger no-load running, do not allow battery discharging yet, realize saving electric energy.
The course of work: correctly connect batteries and AC 220 V power supply, touch the button AN once, control relay J1 adhesive under the battery tension effect, its normally opened contact J1-1 plugged circuit, normally opened contact J1-2, J1-3 connect charging circuit jointly, charger normal starting, ammeter have larger and suitable charging current.Storage battery full charge electric current is little below setting value, current relay J2 discharges, normally opened contact J2-1 disconnects, capacitor C 1 is charged about 5 seconds one-way SCR VS1 conducting, short circuit control relay J1 actuating coil, control relay J1 is discharged, normally opened contact J1-1, J1-2, J1-3 disjunction, deenergization and charging circuit are realized full automatic stop simultaneously.
