Hauv kuv cov lus qhia yav dhau los Kuv tau piav qhia cov ntsiab lus ntawm kev saib xyuas lub zog ntawm lub hnub ci tsis siv lub tshuab. Kuv kuj tseem yeej qhov kev sib tw ntawm 123D rau qhov ntawd. Koj tuaj yeem pom qhov ARDUINO ENERGY METER.

Thaum kawg kuv tshaj tawm kuv qhov tshiab-3 them tus tswj hwm. Qhov tshiab ua haujlwm tau zoo dua thiab ua haujlwm nrog MPPT algorithm.

Koj tuaj yeem pom tag nrho kuv cov phiaj xwm ntawm:

Koj tuaj yeem pom nws los ntawm txhaj rau kab ntawv txuas hauv qab no.

ARDUINO MPPT SOLAR CHARGE CONTROLLER (version-3.0)

Koj tuaj yeem pom kuv li version-1 tus tswj hwm tus nqi los ntawm txhaj rau kab ntawv txuas hauv qab no.

ARDUINO SOLAR CHARGE CONTROLLER (Version 2.0)

Hauv lub hnub ci zog, them tus nqi tswj yog lub plawv ntawm cov kab ke uas tau tsim los tiv thaiv lub roj teeb uas tau them rov qab.

Hauv Is Nrias teb feem coob ntawm cov neeg nyob hauv thaj chaw deb nroog uas tsis muaj cov kab sib txuas hauv lub tebchaws tsis tau txog tam sim no. generators) yog qhov kev xaiv zoo tshaj plaws uas kuv xav. Kuv paub zoo txog qhov mob ntawm lub neej hauv zej zog ib yam li kuv kuj yog los ntawm thaj chaw ntawd. Yog li kuv tsim lub DIY hnub ci them nqi tswj los pab lwm tus ntxiv rau kuv lub tsev. Koj tsis ntseeg, kuv lub tsev tsim hnub ci teeb pom kev zoo pab tau ntau heev thaum lub sijhawm Cyclone Phailin tsis ntev los no.

Hnub ci zog muaj qhov zoo ntawm kev saib xyuas tsawg dua thiab tsis muaj kuab paug tab sis lawv qhov teeb meem tseem ceeb yog kev tsim cov nqi siab, kev hloov pauv hluav taws xob tsawg. Txij li hnub ci vaj huam sib luag tseem muaj qhov hloov pauv me me ua tau zoo, tag nrho cov txheej txheem tus nqi tuaj yeem txo qis siv lub hnub ci kev tswj hwm zoo uas tuaj yeem rho tawm lub zog siab tshaj plaws los ntawm lub vaj huam sib luag.

Tus Tswj Tus Nqi yog dab tsi?

Lub hnub ci tus tswj hwm tswj hwm qhov hluav taws xob thiab tam sim no los ntawm koj lub hnub ci vaj huam sib luag uas tau muab tso nruab nrab ntawm lub hnub ci vaj huam sib luag thiab roj teeb. Raws li qhov hluav taws xob nkag los ntawm lub hnub ci vaj huam sib luag nce, tus tswj tus nqi tswj hwm tus nqi rau lub roj teeb tiv thaiv ib qho twg them dhau.

Hom Charge controller:

1. TU SIAB

2. PWM

3. MPPT

Qhov yooj yim tshaj them tus nqi tswj (ON/OFF hom) tsuas yog saib xyuas lub roj teeb hluav taws xob thiab qhib lub Circuit Court, nres kev them nqi, thaum lub roj teeb hluav taws xob nce mus rau qee qib.

Ntawm 3 tus tswj hwm tus nqi MPPT muaj qhov ua tau zoo tshaj plaws tab sis nws raug nqi ntau thiab xav tau cov teeb meem nyuaj thiab cov txheej txheem. Raws li tus pib nyiam ua haujlwm zoo li kuv kuv xav tias PWM tus tswj hwm tus nqi yog qhov zoo tshaj rau peb uas tau kho ua thawj qhov tseem ceeb ua ntej hnub ci roj teeb.

PWM:

Pulse Width Modulation (PWM) yog qhov ua tau zoo tshaj plaws kom ua tiav lub roj teeb hluav taws xob tas li los ntawm kev kho lub luag haujlwm ntawm cov hloov pauv (MOSFET). Hauv PWM tus tswj tus nqi, tam sim no los ntawm lub hnub ci vaj huam sib luag tapers raws li lub roj teeb qhov xwm txheej thiab rov xav tau. Thaum lub roj teeb hluav taws xob mus txog txoj cai teeb tsa taw tes, PWM cov txheej txheem maj mam txo cov nqi them tam sim no kom tsis txhob muaj cua sov thiab cua sov ntawm lub roj teeb, tab sis kev them nqi txuas ntxiv rov qab ntau lub zog rau lub roj teeb hauv lub sijhawm luv tshaj.

Qhov zoo ntawm PWM tus tswj hwm tus nqi:

1. Kev them nqi siab dua

2. Lub roj teeb ntev dua

3. Txo roj teeb dhau cua sov

4. Txo kev ntxhov siab ntawm lub roj teeb

5. Muaj peev xwm desulfate roj teeb.

Tus tswj tus nqi no tuaj yeem siv rau:

1. Them cov roj teeb uas siv hauv tsev hnub ci

2. Lub teeb hnub ci nyob deb nroog

3. Xov tooj ntawm tes them

Kuv xav tias kuv tau piav ntau yam txog keeb kwm yav dhau los ntawm tus tswj tus nqi.let pib ua tus tswj.

Zoo li kuv cov ntawv qhia ua ntej kuv siv ARDUINO ua tus tswj hwm micro uas suav nrog on-chip PWM thiab ADC.

Kauj Ruam 2: Them Tus Tswj Xyuas Circuit

Kuv faib tag nrho tus nqi tswj hwm Circuit hauv 6 ntu rau kev nkag siab zoo dua

Kauj Ruam 3: Voltage Sensors

Lub ntsuas hluav taws xob tseem ceeb hauv tus tswj hwm tus nqi yog lub ntsuas hluav taws xob uas tuaj yeem siv tau yooj yim los ntawm kev siv hluav taws xob faib hluav taws xob peb yuav tsum nkag siab qhov hluav taws xob los ntawm lub hnub ci vaj huam sib luag thiab lub roj teeb hluav taws xob.

Raws li ARDUINO analog pin input voltage raug txwv rau 5V, Kuv tsim qhov faib hluav taws xob nyob rau hauv txoj hauv kev uas qhov hluav taws xob tso tawm los ntawm nws yuav tsum tsawg dua 5V. Kuv siv 5W (Voc = 10v) hnub ci vaj huam sib luag thiab 6v thiab 5.5Ah SLA roj teeb rau khaws cia lub zog. Yog li kuv yuav tsum nqis qis ob qhov hluav taws xob kom qis dua 5V. Kuv siv R1 = 10k thiab R2 = 4.7K hauv kev nkag siab ob qho tib si qhov hluav taws xob (hnub ci vaj huam sib luag voltage thiab roj teeb voltage). Tus nqi R1 thiab R2 tuaj yeem qis dua ib qho tab sis qhov teeb meem yog tias thaum kev tiv thaiv qis dua tam sim no ntws los ntawm nws vim yog qhov ua rau muaj hwj chim loj (P = I^2R) tso tawm hauv cov cua sov. Yog li tus nqi sib txawv tuaj yeem xaiv tau tab sis kev saib xyuas yuav tsum tau ua kom txo qis lub zog poob hla qhov tsis kam.

Kuv tau tsim tus tswj hwm tus nqi no rau kuv qhov yuav tsum tau ua (6V roj teeb thiab 5w, 6V lub hnub ci vaj huam sib luag), rau qhov siab dua koj yuav tsum hloov pauv tus faib qhov sib txawv tus nqi.

Hauv txoj cai kuv tau teev npe qhov sib txawv "solar_volt" rau qhov hluav taws xob los ntawm lub hnub ci vaj huam sib luag thiab "bat_volt" rau roj teeb hluav taws xob.

Vout = R2/(R1+R2)*V

cia vaj huam sib luag voltage = 9V thaum tshav ntuj ci

R1 = 10k thiab R2 = 4.7 k

solar_volt = 4.7/(10+4.7)*9.0 = 2.877v

cia lub roj teeb voltage yog 7V

bat_volt = 4.7/(10+4.7)*7.0 = 2.238v

Ob qhov hluav taws xob los ntawm kev faib hluav taws xob qis dua 5v thiab haum rau ARDUINO analog pin

ADC Calibration:

cia ua piv txwv:

qhov tseeb volt/divider tso tawm = 3.127 2.43 V yog eqv rau 520 ADC

1 yog eqv rau.004673V

Siv txoj hauv kev no los ntsuas qhov ntsuas.

ARDUINO CODE:

rau (int i = 0; i <150; i ++) {sample1+= analogRead (A0); // nyeem qhov hluav taws xob nkag los ntawm lub hnub ci vaj huam sib luag

qauv 2+= analogRead (A1); // nyeem cov roj teeb voltage

ncua (2);

}

qauv 1 = qauv 1/150;

qauv 2 = qauv 2/150;

solar_volt = (qauv1* 4.673* 3.127)/1000;

bat_volt = (qauv 2* 4.673* 3.127)/1000;

Txog ADC kev ntsuas ntsuas xa mus rau kuv cov lus qhia yav dhau los uas kuv tau piav qhia tob.
