Nyob zoo cov menyuam !!
Lub charger no kuv tau ua haujlwm zoo rau kuv. Kuv tau them nyiaj thiab tso kuv lub roj teeb ntau zaus kom paub txog qhov them nqi hluav taws xob txwv thiab kev txaus siab tam sim no. Lub charger kuv tau tsim ntawm no yog raws li kuv tshawb fawb los ntawm internet thiab kev sim uas kuv tau ua nrog lub roj teeb no.
Kuv tau siv sijhawm ntau hnub los tsim lub charger no. Txhua txhua hnub kuv tau siv los sim sib txawv Circuit Court topology kom tau txais qhov tsim nyog los ntawm lub charger. Thaum kawg, Kuv tau mus txog qhov kev sib tw no uas yog muab rau kuv txaus siab tso tawm thiab kev ua tau zoo. LM393 yog ob tus lej sib piv IC uas yog lub plawv ntawm Circuit no. Muaj ob lub LED tam sim no nyob rau hauv Circuit Court Liab thiab Ntsuab. Liab qhia tias them nyiaj thiab ntsuab qhia tias them tag nrho.
NCO TSEG: Yog tias lub roj teeb tsis txuas nrog thiab muab khoom xa mus ces ntsuab ntsuab yuav ib txwm tig rau. Txhawm rau zam qhov no koj tuaj yeem siv qhov hloov pauv sib txuas ua ke nrog lub xov tooj hluav taws xob.
Nta 1. Charging qhia
2. Txhua tus nqi qhia
3. Txoj kev tiv thaiv tam sim no
4. Flat Them
Thaum lub sijhawm them nyiaj liab liab tig rau ON thiab thaum lub roj teeb ze rau them tag nrho ntsuab coj los tseem tig rau. Tom qab ua tiav kev them tag nrho liab coj tawm thiab ntsuab tseem ON, qhov no txhais tau tias lub roj teeb tam sim no nyob rau theem ntab. Qhov tam sim no ntws los ntawm lub roj teeb yuav yog 20ma.
Khoom siv
- LM393 IC -1nos
- IC puag - 1 nos
- Resistors- 10K, 2.2K, 1K, 680ohm, 470ohm- Txhua yam yog 1/4W ntsuas thiab Ob qho 10ohm-2W ntsuas
- Preset - 10K - 1nos
- Zener Diode - 5.1V/2W
- Capacitors - 10uf/25V - 2nos
- Transistor - TIP31C - 1nos, BC547 - 1nos
- Coj - Liab thiab Ntsuab -5mm
Kauj Ruam 1: Daim duab Circuit Court
Lub charger tau ua haujlwm hauv 7V DC. Hauv daim duab hluav taws xob, J2 yog lub davhlau ya nyob twg nkag thiab J1 yog lub davhlau ya nyob twg. Txhawm rau kom tau txais 7V DC Kuv tau siv tus nqi hloov pauv thiab tus choj txuas tag nrho siv 12V/1A hloov pauv. Koj kuj tseem tuaj yeem hloov kho qhov ntsuas hluav taws xob siv LM317 tsis txhob siv cov hloov pauv hloov pauv. Nyem rau qhov no kom paub txog qhov hloov pauv nyiaj kuv tau siv.
Tam sim no Txwv
Kev them nqi tam sim no tau teeb tsa los ntawm kev siv ob 10ohm resistors, 10K potentiometer, thiab TIP31C transistor. Ntawm no kuv siv lub roj teeb 1.5AH thiab kuv txiav txim siab them lub roj teeb ntawm C/5 tus nqi (1500ma/5 = 300ma). Los ntawm kev kho lub lauj kaub 10K peb tuaj yeem teeb tsa them tam sim no rau 300ma. Thaum xub thawj, lub roj teeb yuav raug them ntawm 300ma, txij li tus tiv thaiv tau txuas nrog ua ke nrog roj teeb qhov hluav taws xob poob hla tus tiv thaiv yuav yog 5x0.3A = 1.5V. Voltage) mus rau 5.3V (Them Tus Nqi Tag Nrho). Thaum lub roj teeb tsub sijhawm ua haujlwm them lub sijhawm tam sim no txo qis. Yog li thaum qhov tam sim no txo qis qhov poob hla tus tiv thaiv kuj tseem yuav txo qis.
Tus nqi tiv thaiv uas kuv tau suav yog siv tus lej 7- 5.5/0.3 = 5ohm. Txij li thaum kuv tsis tau txais 5ohm resistors Kuv siv ob 10ohm resistors nyob rau hauv parallel. Lub zog ntsuas ntawm tus tiv thaiv tuaj yeem suav los ntawm kev siv tus lej 0.3x0.3x5 = 0.45W. A 0.5W xav tau tab sis kuv siv 2W txij li nws tau nyob hauv kuv lub thawv ntim khoom.
NCO TSEG: Yog tias koj qhov ntsuas AH ntau dua 1.5 thiab koj xav kom nce kev them nqi tam sim no, hloov tus nqi ntawm resistors R7 thiab R2 siv tus qauv 7-5.5/ them tam sim no
Ntab Them
Thaum qhov hluav taws xob hla lub roj teeb nce siab dua 5.1V (Zener voltage) transistor Q2 tig rau thiab lub teeb ntsuab ntsuab teeb, txij li lub hauv paus ntawm transistor Q1 txuas nrog tus neeg khaws khoom ntawm Q2, lub hauv paus tam sim no rau Q1 txo qis. Thiaj li, Emitter qhov hluav taws xob ntawm Q1 txo qis rau 5.1V. Nyob rau theem no, ntab them nyiaj tau pib. Qhov no yuav tiv thaiv lub roj teeb los ntawm kev tso tawm tus kheej.
Kauj Ruam 2: PCB Txheej Txheem
Kuv siv Proteus tsim chav los kos cov txheej txheem PCB thiab cov txheej txheem ntawm qhov Circuit no. Yog tias koj xav etch lub rooj tsavxwm no hauv tsev saib qee cov vis dis aus youtube cuam tshuam nrog PCB etching.
Kauj Ruam 3: Tiav Board
Tom qab muab cov khoom sib dhos thiab ua kom zoo nws ua kom lub rooj tsav xwm hauv Circuit Court tau npaj tiav. Muab cov cua sov tso rau transistor Q1 txhawm rau ua kom sov sov.
Kuv tau tshaj tawm yav dhau los lub roj teeb them tab sis nws tau txais qee qhov tsis zoo. Kuv vam tias cov lus qhia no yuav pab txhua tus neeg uas tab tom nrhiav 4V txhuas-kua qaub roj teeb them.

Yooj Yim 4V Lead Acid Battery Charger: Ntawm no kuv tab tom qhia Lead acid roj teeb them. 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 tas li tam sim no lub charger piv txwv li thaum
