The operation principle of the utility model is following: the 220V civil power is told three tunnel different alternating currents through transformer 5; Be 12V, 24V, 36V, when load-side does not connect storage battery, the voltage identification of storage battery and polarity identification circuit no signal; So the polarity switching and the voltage conversion circuit of storage battery are not worked; Load-side A, the output of B no-voltage even A, B short circuit are not had short circuit current yet, thereby have realized the short circuit current protection.As charging device A, when B inserts storage battery; No matter the negative still positive A of B of the positive B of A is negative; Voltage all can arrive series resistance R3, R4 through rectifier bridge GB2; Modulus conversion chip ADC2 will change into digital signal to the aanalogvoltage at resistance R 4 two ends and sent into single-chip microprocessor MCU 2 this moment, and single-chip microprocessor MCU 2 is made judgement after receiving the data that ADC2 sends here, controls voltage conversion circuit work then.The voltage of batteries mostly is 12V, 24V or 36V; If the voltage that single-chip microprocessor MCU 2 detects A, B two ends is between 7～15V; Just with 12V voltage as reference voltage, pin P2.4 exports high level, relay J 2 set; Charging voltage just has been switched to 12V, shows 12V through charactron LED1, LED2 simultaneously; If single-chip microprocessor MCU 2 detect A, B two ends voltage between 17～28V, just with 24V voltage as reference voltage, pin P2.3 exports high level, relay J 3 set, charging voltage just has been switched to 24V, lets charactron LED1, LED2 show 24V simultaneously; If single-chip microprocessor MCU 2 detect A, B two ends voltage between 28～40V, just with 36V voltage as reference voltage, pin P2.2 exports high level, relay J 4 set, charging voltage just has been switched to 36V, lets charactron LED1, LED2 show 36V simultaneously.Treating that single-chip microprocessor MCU 2 collects voltage signal and gathers the accumulator polarity signal later on again, is that the positive A of B is negative in order to avoid A, B end no storage battery is mistaken as when inserting, and polarity identification circuit is made up of diode D1, photoelectrical coupler V, resistance R 13; Characteristic by diode and optocoupler can know, if A connect positive B connect negative, photoelectrical coupler V conducting; The P3.7 of single-chip microprocessor MCU 2 becomes low level, after single-chip microprocessor MCU 2 detects the P3.7 step-down, makes P2.1 output high level; Then J5 set, thus normally charge for storage battery, if B meets positive A and connects negative; Not conducting of photoelectrical coupler V, the P3.7 of single-chip microprocessor MCU 2 is a high level, it is high level that single-chip microprocessor MCU 2 detects P3.7; Can make P2.0 output high level, then J6 set is similarly storage battery and normally charges.
The P2.7 pin of MCU2 will sender's wave impulse when charging normal, so FET DS1 can send charging pulse, has prevented that accumulator plate from producing too much bubble.When having charging current to flow through wire resistor R2; Must produce pressure drop at resistance R 2 two ends; The electric current that flows through resistance R 2 is big more, and pressure drop is big more, and modulus conversion chip is sent the voltage signal at resistance R 2 two ends into single-chip microprocessor MCU 1; Single-chip microprocessor MCU 1 with the voltage signal analytical calculation of sending here after, show through charactron LED3, LED4.Voltage can slowly raise during charge in batteries; Theoretical voltage value after single-chip microprocessor MCU 1 can be full of according to the voltage signal of analog to digital converter ADC2 and storage battery is made comparisons; Thereby calculate the current electric quantity (representing) of storage battery, show through charactron LED3, LED4 then with percentage.Display circuit realizes that through dynamic scan multidigit nixie tube shows.When battery tension reached threshold voltage, when promptly electric weight was full of, the P2.5 of single-chip microprocessor MCU 2 exported high level, and relay J 1 set is the normally closed interlock of J1 because transformer 5 connects, so transformer 5 breaks off after the J1 set, charging stops.After charging accumulator removes; Because charging voltage is pulse voltage, the voltage of output terminals A, B must promising zero the moment, when voltage is zero; The voltage at resistance R 4 two ends is similarly zero; Each I/O mouth restPosed after MCU2 detected zero-signal, so charging device also returns to initial condition, waited for the access of next group charging accumulator.
In addition, the also additional function that reparation is arranged and activate storage battery of this charging device, after pressing function conversion key 19, the P3.6 of single-chip microprocessor MCU becomes low level; It is that low level is just called the internal repair program that single-chip microcomputer detects P3.6, is earlier to be full of the storage battery charging back and to turn-off charging device; P2.7 exports high level again, FET DS1 conducting, and storage battery is just through resistance wire R1 discharge discharge; After single-chip microprocessor MCU 2 detects battery tension and drops to certain value through ADC1, promptly put finish after, turn-off DS1; Simultaneously connect charging device again and charge a battery, so carry out 2～3 circulations, promptly reached the purpose that activates and repair storage battery.
Need to replenish be single-chip microprocessor MCU 1 with the working method of MCU2 all by the program decision that writes.When electric weight detected, when inserting the 12V storage battery, single-chip microprocessor MCU 2 identified the voltage of storage battery before this, again the current voltage of storage battery and 12V storage battery completely the theoretical voltage behind the electricity make comparisons, thereby calculate the current electric quantity of storage battery; When inserting the 24V storage battery, single-chip microprocessor MCU 2 is to identify the voltage of storage battery earlier equally, again the current voltage of storage battery and 24V storage battery completely the theoretical voltage behind the electricity make comparisons, thereby calculate the current electric quantity of storage battery; When the storage battery of 36V also is same principle.That is to say the storage battery that no matter inserts several volts, single-chip microcomputer all can access corresponding with it voltage reference, can both demonstrate the current electric quantity of storage battery after the calculating more accurately.
