Ntawm no kuv tab tom qhia Lead acid battery charger. Nws yog siv los them lub roj teeb 4V 1.5AH. C-tus nqi ntawm lub roj teeb no yog C/4 (1.5/4 = 0.375A) uas txhais tau tias kev them nqi tam sim no yog txog 400ma. Qhov no yog qhov ntsuas hluav taws xob tsis tu ncua tam sim no piv txwv li thaum pib them nws siv txog 400ma thiab thaum nce mus txog qhov them tag nrho cov nqi them tam sim no txo qis. Thaum lub roj teeb tau them tas ces them tam sim no yog 40ma. Yog li lub charger no muaj kev tiv thaiv kev them nyiaj ntau dhau. Kuj tseem them nyiaj (Liab Coj) thiab Them Nqi Tag Nrho (Ntsuab Ntsuab) qhia. Cov coj liab yuav tua thiab teeb ntsuab ntsuab thaum them tag lawm.

NCO TSEG: Thaum lub roj teeb tag nrho thiab thaum txuas nrog lub roj teeb ntsuab ntsuab yuav ci rau qee lub sijhawm. Nov yog lub sijhawm xav tau los ntawm IC hauv kab lus no kom nkag siab txog qib hluav taws xob ntawm lub roj teeb. Tom qab qee lub sijhawm (kwv yees li 10-20 vib nas this) lub teeb liab liab yuav ci, qhia tias tau them nqi pib.

NCO TSEG: Qhov no tsis yog lub charger zoo tshaj plaws rau cov roj teeb ua kua qaub thaum piv nrog cov khoom siv muaj npe muaj nyob hauv khw. Tab sis lub roj teeb no yuav tiv thaiv lub roj teeb los ntawm kev them ntau dua thiab nws yuav muab them thiab them tag nrho.

Khoom siv

Cov Cheeb Tsam Yuav Tsum Tau:

1) LM358 IC

2) 5mm Coj: Ntsuab, Liab

3) Resistors: 47, 47, 1K, 1.5K Txhua tus yog 1/4W

4) Cov Hluav Taws Xob Hluav Taws Xob: 10uf 25v -2 nos

5) Zener Diode: 4.2V 1W

6) Transistor: BD139

Kauj ruam 1: Circuit Court

Cov tswv yim hluav taws xob yog 6V, muab rau ntawm J1 cov davhlau ya nyob twg thiab cov zis tawm los ntawm J2 cov dav hlau. Txheeb xyuas qhov polarity ua ntej txuas cov khoom siv. Lub zog hluav taws xob tuaj yeem ua tau siv 9V, 500ma hloov pauv, thiab tus choj txuas. Txhawm rau kom tau txais 6V cov cai tswj hwm koj tuaj yeem siv 7806 IC

NCO TSEG: Yog tias peb siv 1A hloov pauv ces pib them tam sim no yuav ntau dua 400ma (450ma-500ma). Txhua zaus sim siv 500ma hloov pauv.

Kauj ruam 2: PCB

Cov txheej txheem PCB ntawm lub Circuit Court tau muab rau ntawm no.

Kauj Ruam 3: Tiav Board

Koj kuj tseem tuaj yeem siv lub voj voog no rau them cov roj teeb uas muaj peev xwm siab dua AH. Lub sijhawm yuav tsum tau them lub roj teeb yuav nce ntxiv. Rau 1.5AH roj teeb lub sijhawm kwv yees xav tau yog 4 teev. Lub sijhawm them yuav sib txawv raws li kev siv lub roj teeb.
