2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Qhov no yog txoj haujlwm hais txog them Lithium - Ion roj teeb nrog lub xov tooj ntawm tes.

* qee qhov kev kho kuv ua kom txhim kho them thaum lub caij ntuj no.

** solar cell yuav tsum yog 6 V thiab tam sim no (lossis lub zog) tuaj yeem hloov pauv tau, zoo li 500 mAh lossis 1Ah.

*** diode los tiv thaiv TP4056 los ntawm kev thim rov qab yuav tsum muaj qhov poob qis ("poob tawm"). Kuv siv qhov tsis zoo, uas siv 0, 5-0, 6 V, uas yog ntau heev. Koj tuaj yeem siv Schottky diode, uas tsuas yog siv 0, 1 - 0, 2 V.

Kauj Ruam 1: Cov khoom siv (txuas yog koom nrog)

1 x Hnub ci cell 6V

Txuas: 6V 1W

Txuas: (ntau lub hlwb nrog ntau lub zog sib txawv)

Txuas: (ntau rau xaiv)

1 x Li - Ion charger board TP4056 (xaiv pawg thawj coj nrog 4 tso zis - 2 rau roj teeb, 2 rau txuas lub cuab yeej)

Txuas: (5 daim, cca 0.20 $ / thooj)

Txuas: (1 thooj, 0.29 $ / thooj)

1 x Schottky diode (zoo dua, 0, 1 - 0, 2 qhov hluav taws xob poob) lossis 1N4148 (phem dua, 0, 5 - 0, 6 qhov hluav taws xob poob)

Txuas: (teeb ntawm diodes) (hloov kho)

Txuas: (1N4148)

1 x Lithium - Ion roj teeb (18650), Kuv yuav 1 pluag, koj tuaj yeem xaiv tau zoo dua nrog lub peev xwm nyob ib puag ncig 2000 mAh - 3000 mAh, Txuas: Lithium -ion roj teeb

1 x Lithium - Ion roj teeb tuav

Txuas: tus tuav lub roj teeb

1 x cables, Kuv siv internet txuas nrog 6 xov hlau sab hauv lossis awg 22 cov khoom siv hlau

Txuas:

zoo: teeb tsa AWG 22 kab

ethernet cable: ethernet cable (xav tau txiav tawm 6 xov hlau)

1 x cuab yeej cuab yeej (chaw nres tsheb, tin, rosin thiab lwm yam)

Kauj Ruam 2: Txoj Cai Hnub Ci Cell

* lub hnub ci cell yuav tsum siab tshaj 6V, vim TP4056 muaj qhov siab tshaj 6V. Nws yog qhov zoo dua 5V.

* tam sim no los ntawm lub hnub ci cell (lossis lub zog) tuaj yeem hloov pauv tau, vim TP4056 "noj" ntau npaum li nws xav tau. Yog li koj tuaj yeem xaiv 500 mAh hnub ci cell lossis 1 Ah solar cell.

Rau Li - Ion roj teeb Kuv xaiv lub hnub ci cell nrog 5V thiab 160 mA. Txhawm rau xaiv lub hnub ci cell, koj yuav tsum xaiv:

1. voltage ntawm hnub ci cell 1.5 x voltage ntawm roj teeb, yog li 3.7V rau 4.2 V ntawm Li-Ion yog sib npaug ntawm 5.55 V txog 6.3 V ntawm lub hnub ci cell.

2. tam sim no ntawm lub hnub ci cell yuav tsum muaj 1/10 ntawm lub peev xwm roj teeb diveded los ntawm 1 teev (rau Ni Mh roj teeb). Kuv siv tib txoj cai rau Li - Ion roj teeb. Nws yog hu ua C - tus nqi txoj cai. Yog li Yog tias kuv muaj 500 mAh roj teeb, kuv yuav tsum xaiv 50 mA sollar cell. Cov roj teeb Li-Ion zoo muaj 2000 mAh, yog li tam sim no yuav tsum nyob ib puag ncig 200 mAh lossis 1.2 W.

Kuv siv roj teeb tsis zoo Li -Ion nrog ntsuas ib puag ncig 600 mAh. Rau qhov ntawd, kuv yuav tsum xaiv lub hnub ci cell nrog 60 mA ncov, lossis 0.360 W (POWER = CURRENT X VOLTAGE).

Kauj Ruam 3: Lithium - Ion Roj teeb 18650

Kuv pom lub vev xaib zoo nrog kuaj lithium -ion roj teeb. Feem ntau muaj 3400 mAh siab tshaj plaws.

Nov yog:

Nov yog qee qhov kev xav ntawm them lawv:

Kauj ruam 4: Circuit Court

Circuit yog qhov yooj yim, tab sis kuv piav qhia nws ntawm no.

Txuas lub davhlau ya nyob twg zoo ntawm lub hnub ci cell mus rau anode ntawm diode. Txuas qhov tsis zoo ntawm qhov diode mus rau IN+ (cov tswv yim zoo) ntawm TP4056. Kuv siv diode vim qhov rov qab tam sim no.

Kuj tseem txuas qhov tsis zoo ntawm lub hnub ci cell mus rau IN- (input tsis zoo) ntawm TP4056. Thaum kawg txuas lub roj teeb, lub davhlau ya nyob twg zoo ntawm roj teeb rau BAT + ntawm TP4056, zoo ib yam tsis zoo lub davhlau ya nyob twg.

Kauj Ruam 5: LED Diodes ntawm TP Board

Ntawm lub nkoj, muaj 2 diodes, uas tseem suav qee lub zog. Kuv tshem lawv nrog riam. Kos duab.

Kauj Ruam 6: Xam Kev Ua Tau Zoo

Ntsuam xyuas koj them, koj tuaj yeem txuas koj lub ntsuas cua rau lub hnub ci, lossis roj teeb.

Xeem:

pos huab, nrog me ntsis tshav ntuj 10 mA (tso tawm tam sim no los ntawm TP4056), 24 mA (los ntawm hnub ci cell)

pos huab, tsis ncaj qha rau lub hnub 0.87 mA (TP4056), 5.1 mA (hnub ci cell)

tshav ntuj, ncaj qha tshav ntuj 26 mA (TP4056), 89 mA (hnub ci cell)

Raws li pveducation.org lub vev xaib, koj tuaj yeem suav ncaj qha hnub ci hluav taws xob hauv kW. Tsuas yog sau koj lub tsev lattitude thiab ntev ntev. Thiab nco lub sijhawm, vim hluav taws xob thaum nruab hnub sib txawv. Kuv tau txais ib ncig 1 kW/m2.

Yog li, lub hnub ci cell muab rau kuv 89 mA, thiab 5V, yog li nws muab 445 mW, lossis 0.445 W. Nto hnub ci ntawm tes yog ib puag ncig 70 cm2 (feem ntau tsuas yog kab me me ua kom muaj zog, yog li ib puag ncig 30 cm2).

Hnub ci cell tawm = 0.089A x 5 V = 0.445 W

TP4056 tso tawm = 0.026 A x 4 V = 0.104 W

Txhawm rau xam ntau npaum li cas lub hnub ci hluav taws xob poob rau 30 cm2 raws li pv kev kawm lub vev xaib, peb yuav tsum hloov pauv saum npoo mus rau m2, nws yog 0. 00 30 m2. Qhov tshwm sim hluav taws xob yog 1000 x 0.003 = 3 W.

Teeb meem hluav taws xob = 3W

Kev ua haujlwm ntawm hnub ci cell = 0.445 W / 3 W = 0.1483 = 14.8 %.

Kev ua tau zoo ntawm TP4056 = 0.104 W / 0.445 W = 23.37 %

Kev ua haujlwm tag nrho ntawm qhov system = 0.104 W / 3W = 0.034666 = 3.46 %.

Yog li tag nrho kev ua haujlwm tsis ntau, tab sis pab. Koj puas nco C-tus nqi? Rau txoj haujlwm no, yuav tsum muaj lub hnub ci loj dua. Kuv sim rau lub Cuaj Hlis, uas yog nruab nrab ntawm lub caij ntuj no thiab lub caij ntuj sov. Kuv siv roj teeb rau kuv tus esp logger, uas yuav tsum muaj sia nyob thaum lub caij ntuj no, lub caij ntuj sov yog qhov zoo. Kuv yuav sim lwm lub hnub ci cell, yav tom ntej, thiab qhia kuv cov txiaj ntsig.

Kauj Ruam 7: Ntxiv: Thingspeak Graph

Kuv sim roj teeb hluav taws xob nrog kuv tus esp logger. Kuv tau txais daim duab ntawm yam khoom. Cov txiaj ntsig tau nyob hauv ADC qhov tseem ceeb, tsis yog qhov hluav taws xob. Qhov muaj txiaj ntsig 720 yog sib npaug ntawm roj teeb nrog 4.07 V. Kuv siv qhov tsis zoo 600 mA Lithium - Ion roj teeb.
