Yuav ua li cas roj teeb xws li. Tus nqi xws li Li-Ion roj teeb-

Lub controllers lawv tus kheej yuav pab tau kiag li lawm. Thiab nyob rau hauv thiaj li yuav to taub zoo dua no lub npe, koj yuav tsum ua hauj lwm nrog ib tug piv txwv. Yog li ntawd, peb xav txog lub roj teeb yuav nqi xws li. Yuav ua li cas yog nws? Yuav ua li cas thiab? Yuav ua li cas nta ua hauj lwm muaj?

Li cas rau cov them nyiaj xws li

Nws ua hauj lwm pab mus soj ntsuam cov yuav txo tau ntawm lub zog losses thiab expenditure. Ua ntej, nws yog nyob rau hauv them nyiaj ntawm saib xyuas hloov dua siab tshiab ntawm hluav taws xob lub zog rau hauv tshuaj zog, mus rau nyob rau hauv lub tom ntej yuav tsum tau yuav tsum tau mov circuits los yog kiag li lawm. Ua ib tug them nyiaj xws li nrog koj txhais tes yog tsis yooj yim. Tab sis nws kuj yuav kos los ntawm lub hwj huam mov, uas yog tawm ntawm kev txiav txim.

Yuav ua li cas puas muaj tus xws li

Ntawm cov hoob kawm, tus universal lub tswvyim tsis muaj nyob. Tab sis muaj ntau yam nyob rau hauv lawv cov chaw ua hauj lwm siv ob posdtroechnyh resistor uas tswj sab sauv thiab sab voltage txwv. Thaum nws mus dhau cov kev txwv koj qhia kom meej, sis pib nrog relay coils thiab nws yog muab rau. Thaum nws khiav khiav, lub voltage dauv rau hauv qab no ib tug tej yam, pre-determined theem technically. Ntawm no nws yog tsim nyog los tham txog qhov tseeb hais tias muaj yog ib tug txawv ntau yam. Yog li, lub roj teeb yuav tsum tau ntsia thiab peb, tsib thiab kaum ob, thiab kaum tsib volts. Raws, txhua yam nyob rau hauv lub kho vajtse siv. Cia saib yuav ua li cas tus nqi xws li nyob rau hauv txawv tus neeg mob.

Yuav ua li cas yog cov hom

Nws yuav tsum tau muab sau tseg loj muaj ntau haiv neeg, uas muaj peev xwm khav nqi xws li. Yog hais tias peb tham txog lawv cov views, cia peb ua ib tug kev faib nyob rau hauv lub Scope ntawm daim ntawv thov:

  1. Rau zog tauj dua tshiab.
  2. Rau khoom vaj khoom tsev.
  3. Rau mobile pab kiag li lawm.

Ntawm cov hoob kawm, cov hom lawv tus kheej ntau npaum li cas. Tab sis raws li peb xav txog tus nqi xws li los ntawm ib tug general taw tes ntawm view, nws yog txaus rau peb thiab lawv. Yog hais tias peb tham txog cov uas yog siv rau cov solar panels thiab cua turbines, nyob rau hauv uas lub sab sauv voltage txwv no feem ntau yog sib npaug zos rau 15 volts, thaum lub sab - 12 B. Lub roj teeb yuav tsim nyob rau hauv tus txheej txheem 12 V fais fab mov yog kev cob cog rua rau nws nrog fine kaw relay hu. Yuav ua li cas tshwm sim thaum lub roj teeb voltage tshaj 15 V? Nyob rau hauv xws li mob, xws li yog nqa tawm Circuit Court relay. Raws li ib tug tshwm sim, lub roj teeb fais fab qhov chaw yog hloov mus rau lub ballast load. Nws yuav tsum tau muab sau tseg hais tias nws tsis yog tshwj xeeb xav kom muab tso rau solar panels vim muaj tej kev phiv. Tab sis rau cua generators , lawv yuav tsum. Khoom vaj khoom tsev thiab mobile pab kiag li lawm muaj lawv tus kheej cov yam ntxwv. Wherein lub roj teeb xws li cov ntsiav tshuaj, thiab kov ib tug khawm cell xov tooj yog zoo tib yam.

Saib mus rau hauv lub lithium-ion roj teeb cell xov tooj

Yog hais tias koj tuaj tos qhib tej roj teeb, koj mam li paub hais tias cov me me soldered mus rau lub terminals ntawm lub cell Circuit Court board. Nws hu ua ib tug tiv thaiv Circuit Court. Qhov tseeb hais tias lithium-ion roj teeb yuav tsum tau tas li saib xyuas. Li ib txwm maub los yog ib tug tej yam me me Circuit Court board uas Circuit Court raws li ua los ntawm SMD-Cheebtsam. Nws, nyob rau hauv lem, yog muab faib ua ob chips - ib tug ntawm lawv yog ib tug tswj, thiab rau lwm yam - lub thawj. Wb tham nyob rau hauv ntau yam txog tus thib ob.

executive tswvyim

Nws yog raws li nyob rau hauv transistors MOSFET. Feem ntau, muaj yog ob tug. Tus heev tib nti yuav muaj 6 los yog 8 pins. Nyias ua nyias xwb tswj thiab raws lub roj teeb cell siv ob teb-nyhuv transistors uas yog nyob rau hauv tib lub tsev. Yog li ntawd, ib tug muaj peev xwm txuas los yog rho lub load. Ib tug thib ob transistor ua tib txiav txim, tab sis rau cov fais fab mov (uas ua raws li cov charger). Vim rau qhov kev siv ntawm xws li ib tug tswvyim yuav cuam tshuam rau roj teeb lub neej tsis muaj teeb meem. Yog hais tias qhov kev kawm, nws yuav siv tau nyob rau hauv lwm qhov chaw. Tab sis nws yuav tsum tau borne nyob rau hauv lub siab hais tias lub roj teeb yuav nqi xws Circuit Court thiab nws muaj peev xwm tsuas tau mus thov kom apparatuses thiab hais tias muaj ib tug tsawg ntau yam ntawm lub lag luam. Yog xav paub ntxiv cov ntsiab lus hais txog cov nta, peb tam sim no tham txog.

Kev pab tiv thaiv tiv thaiv overcharging

Qhov tseeb yog hais tias yog lub roj teeb voltage ntawm lub lithium tshaj 4.2, tej zaum nws yuav overheat thiab txawm tawg. Rau no matched hais xws chips, uas yuav nres thaum tus nqi ntawm qhov ntsuas. Thiab feem ntau, kom txog thaum lub voltage nce mus txog lub hom phiaj ntawm 4-4,1 V los ntawm kev siv los yog nyob rau hauv tus txheej txheem ntawm yus tus kheej-paug, tsis muaj ntxiv them yog tsis tau. Qhov no yog ib qho tseem ceeb muaj nuj nqi uas yog muab rau tus xws li them nyiaj rau cov lithium roj teeb.

Kev pab tiv thaiv tiv thaiv overcharge

Thaum lub voltage nce mus txog ib tug tseem ceeb heev uas tsis muaj qhov tseem ceeb uas ua rau problematic hauj lwm ntawm lub ntaus ntawv nws tus kheej (feem ntau yog nyob rau hauv ntau 2,3-2,5V), ces koj lem tawm lub sib nug xov MOSFET-transistor, uas yog lub luag hauj lwm rau qhov tam sim no mov ntawm cov xov tooj txawb. Tom ntej no yog ib txoj kev hloov mus pw tsaug zog hom muaj tsawg heev zog noj. Thiab ces muaj ib tug heev interesting nam ntawm lub chaw ua hauj lwm. Yog li ntawd, thaum lub roj teeb cell voltage yog ntau tshaj 2.9-3.1 V, lub mobile ntaus ntawv yuav tsum enabled rau tej lag luam. Tej zaum nej yuav pom tias yog tias thaum plugging lub xov tooj, nws qhia tau hais tias hais tias muaj yog ib tug xwb, tab sis lub lem thiab khiav lag luam feem ntau tsis xav mus.

kev tiv thaiv mechanisms

Nws yuav tsum tau muab sau tseg hais tias tus nqi xws li muaj ib tug xov tooj ntawm cov ntsiab uas yuav tsum tiv thaiv tej yam tsis zoo los. Yog li ntawd, qhov no cab diodes uas cov txheej txheem ntawm nyob rau hauv lub teb-nyhuv transistors, tus nqi kom paub tias Circuit Court thiab ib tug ob peb me ntxiv. Aub, yog, thiab yog hais tias koj muaj peev xwm mus saib lub roj teeb yuav nqi maub los thiab kawm kev ua tau zoo zog qhov twg los, nws txoj kev ua yuav tsum tau rov qab txawm yog hais tias tus "tuag". Ntawm cov hoob kawm, qhov no implies ib tug cessation ntawm kev ua hauj lwm, tsis muaj tawg los yog meltdown. Nyob rau hauv cov ntaub ntawv no, yuav pab tau tshwj xeeb pab kiag li lawm uas ua ib tug tshwj xeeb "rov qab" xwb. Ntawm cov hoob kawm, lawv yuav ua hauj lwm rau ib tug ntev lub sij hawm - cov txheej txheem yuav luag nyob rau dozens ntawm cov sij hawm, tab sis lub roj teeb tom qab kawm tiav ntawm lub chaw ua hauj lwm yuav tsum tau yuav luag li zoo li tshiab.

xaus

Raws li koj tau pom, lub maub los them nyiaj Li-Ion-roj teeb plays ib qho tseem ceeb luag hauj lwm nyob rau hauv kom ntseeg tau tias lub caij ntawm kev ua tau zoo ntawm mobile pab kiag li lawm thiab muaj tej yam zoo nyob rau hauv lawv lub neej. Vim lub simplicity ntawm lawv siv yuav pom nyob rau hauv yuav luag txhua lub xov tooj los yog ntsiav tshuaj. Yog hais tias muaj yog ib tug xav xav pom nrog nws tus kheej ob lub qhov muag thiab ob txhais tes mus kov tus xws li them nyiaj Li-Ion-roj teeb thiab nws txheem, ces parsing nws yuav tsum tau nco ntsoov tias kev ua hauj lwm yog nqa tawm nrog ib tug tshuaj elementomv, li ntawd, ua tau tej yam ceev faj.
