Dab tsi yog Amp-Hour (Ah)
Hauv thaj tsam ntawm cov roj teeb, Ampere-teev (Ah) yog qhov tseem ceeb ntawm kev ntsuas hluav taws xob, qhia txog lub roj teeb lub zog cia. Muab qhov yooj yim, ib qho ampere-teev sawv cev rau qhov ntau ntawm cov nqi xa los ntawm ib qho tam sim no ntawm ib ampere tshaj li ntawm ib teev. Qhov kev ntsuas no yog qhov tseem ceeb hauv kev ntsuas qhov ua tau zoo ntawm lub roj teeb tuaj yeem tiv taus qhov tshwj xeeb amperage.
Cov roj teeb sib txawv, xws li lead-acid thiab Lifepo4, muaj zog sib txawv thiab cov yam ntxwv ntawm electrochemical, cuam tshuam rau lawv cov peev xwm Ah. Qhov ntsuas Ah siab dua txhais tau hais tias lub zog muaj zog ntau dua uas lub roj teeb tuaj yeem xa tuaj. Qhov kev sib txawv no muaj qhov tseem ceeb tshwj xeeb hauv kev teeb tsa hnub ci off-grid, qhov twg muaj kev cia siab thiab muaj zog txaus yog qhov tseem ceeb.
Kilowatt-hour (kWh) yog dab tsi
Nyob rau hauv lub cheeb tsam ntawm cov roj teeb, ib kilowatt-teev (kWh) stands raws li ib tug pivotal chav tsev ntawm lub zog, delineating qhov ntau ntawm hluav taws xob generated los yog noj tshaj ib teev ntawm tus nqi ntawm ib kilowatt. Tshwj xeeb tshaj yog nyob rau hauv lub npe ntawm lub hnub ci roj teeb, kWh ua hauj lwm raws li ib qho tseem ceeb metric, muab ib qho kev nkag siab ntawm lub roj teeb tag nrho lub zog cia peev xwm.
Hauv cov ntsiab lus, ib kilowatt-teev encapsulates tus nqi hluav taws xob siv hluav taws xob los yog tsim tawm hauv ib teev, ua haujlwm ntawm lub zog tso zis ntawm ib kilowatt. Hloov pauv, lub ampere-teev (Ah) cuam tshuam rau kev ntsuas hluav taws xob, uas sawv cev rau qhov ntim ntawm hluav taws xob coursing los ntawm ib lub voj voog nyob rau tib lub sijhawm. Kev sib raug zoo ntawm cov chav nyob no yog nyob ntawm qhov voltage, muab lub zog sib npaug rau cov khoom tam sim no thiab voltage.

Yuav ua li cas Hloov Amp Teev (Ah) mus Kilowatt Teev (kWh)?
Amp teev (Ah) yog ib chav tsev ntawm cov nqi hluav taws xob feem ntau siv los ntsuas lub peev xwm ntawm lub roj teeb. Nws sawv cev rau tus nqi hluav taws xob hluav taws xob uas lub roj teeb tuaj yeem khaws thiab xa tuaj raws sijhawm. Ib ampere-teev sib npaug ntawm ib qho ampere ntws rau ib teev.
Kilowatt-teev (kWh) yog ib chav tsev ntawm lub zog uas feem ntau siv los ntsuas kev siv hluav taws xob lossis kev tsim khoom dhau sijhawm. Nws ntsuas tus nqi ntawm lub zog siv los yog tsim los ntawm cov khoom siv hluav taws xob lossis qhov system nrog lub zog ntsuas ntawm ib kilowatt (kW) tshaj ib teev.
Kilowatt-teev feem ntau yog siv los ntawm cov nqi hluav taws xob los ntsuas thiab them cov nqi hluav taws xob siv los ntawm tsev neeg, kev lag luam, lossis lwm qhov chaw. Nws kuj tseem siv rau hauv cov tshuab hluav taws xob tauj dua tshiab los ntsuas cov hluav taws xob uas tsim los ntawm cov hnub ci vaj huam sib luag, cua turbines, thiab lwm qhov chaw hauv lub sijhawm tshwj xeeb.
Txhawm rau hloov los ntawm lub peev xwm ntawm cov roj teeb mus rau lub zog, cov mis yuav hloov tau Ah rau kWh:
Formula: Kilowatt Teev = Amp-Hours × Volts ÷ 1000
Abbreviated Formula: kWh = Ah × V ÷ 1000
Piv txwv li, yog tias peb xav hloov 100Ah ntawm 24V rau kWh, lub zog hauv kWh yog 100Ah × 24v÷1000 = 2.4kWh.

Kev piav qhia ntawm cov roj teeb specification sib piv cov qauv rau cov khoom siv hauv tsev
Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, qhov nrov ntawm lithium-ion roj teeb, kev ua lag luam rau lithium roj teeb kev ua tau zoo, tus nqi, kev sib tw ua kom muaj kev xav tau siab dua, tom qab ntawd peb sib phim cov roj teeb tshwj xeeb rau cov khoom siv hauv tsev los tshuaj xyuas cov lus piav qhia ntxaws:
1, Kuv tsis paub tias lub roj teeb loj npaum li cas los siv kom haum rau kuv cov khoom siv hauv tsev, kuv yuav ua li cas?
a: Lub zog ntawm cov khoom siv hauv tsev yog dab tsi;
b: Kom paub seb qhov kev khiav hauj lwm voltage ntawm cov khoom siv hauv tsev yog dab tsi;
c: Lub sijhawm koj cov khoom siv hluav taws xob hauv tsev yuav tsum ua haujlwm npaum li cas;
d: Lub roj teeb loj npaum li cas hauv cov khoom siv hauv tsev;
Piv txwv li 1: Ib qho khoom siv hluav taws xob yog 72W, qhov hluav taws xob ua haujlwm yog 7.2V, yuav tsum tau ua haujlwm rau 3 teev, tsis tas yuav tsum muaj qhov loj me, qhov loj me ntawm cov roj teeb hauv tsev kuv yuav tsum ua kom haum?
Fais fab / Voltage = Tam sim noLub sij hawm = Peev Xwm Raws li saum toj no: 72W / 7.2V = 10A3H = 30Ah Tom qab ntawd nws tau txiav txim siab tias qhov sib piv ntawm cov roj teeb tshwj xeeb rau cov khoom siv no yog: Voltage yog 7.2V, Muaj Peev Xwm yog 30Ah, Qhov Loj tsis tas yuav tsum muaj.
Piv txwv 2: Cov khoom siv hluav taws xob yog 100W, 12V, yuav tsum tau ua haujlwm rau 5 teev, tsis muaj qhov yuav tsum tau muaj, lub roj teeb loj npaum li cas kuv xav tau kom phim?
Fais fab / voltage = tam sim no * lub sij hawm = muaj peev xwm Raws li saum toj no:
100W / 12V = 8.4A * 5H = 42Ah
Tom qab ntawd nws tau muab los ntawm cov lus qhia tshwj xeeb ntawm lub roj teeb sib tw nrog cov khoom siv no: qhov hluav taws xob ntawm 12V, muaj peev xwm ntawm 42Ah, tsis muaj qhov xav tau loj. Nco tseg: feem ntau suav nrog lub peev xwm raws li qhov yuav tsum tau ua ntawm cov khoom siv, lub peev xwm muab 5% mus rau 10% ntawm lub peev xwm txuag; cov theoretical algorithm saum toj no rau kev siv, raws li qhov sib piv ntawm cov khoom siv hauv tsev hauv tsev siv roj teeb yuav tsum yeej.
2, Cov khoom siv hauv tsev yog 100V, pes tsawg V yog qhov kev ua haujlwm ntawm lub roj teeb?
Dab tsi yog qhov ua haujlwm voltage ntau ntawm cov khoom siv hauv tsev, ces phim cov roj teeb hauv tsev.
Lus Cim: Ib qho lithium-ion roj teeb: Nominal voltage: 3.7V Kev khiav hauj lwm voltage: 3.0 txog 4.2V Peev xwm: tuaj yeem siab lossis qis, raws li qhov xav tau tiag tiag.
Piv txwv 1: Lub nominal voltage ntawm ib lub tsev yog 12V, yog li muaj pes tsawg lub roj teeb yuav tsum tau txuas nrog nyob rau hauv series kom ze li ntawm qhov voltage ntawm cov khoom siv hauv tsev?
Cov khoom siv hluav taws xob hluav taws xob / cov roj teeb nominal voltage = cov roj teeb hauv series 12V / 3.7V = 3.2PCS (nws raug nquahu tias tus lej lej tuaj yeem sib npaug lossis nqis, nyob ntawm qhov voltage ntawm cov khoom siv) Tom qab ntawd peb teeb tsa saum toj no ua ib qho cov xwm txheej zoo rau 3 txoj hlua ntawm cov roj teeb.
Nominal voltage: 3.7V * 3 = 11.1V;
Ua haujlwm voltage: (3.03 rau 4.23) 9V txog 12.6V;
Piv txwv 2: Qhov nominal voltage ntawm lub tsev khoom siv yog 14V, yog li yuav tsum muaj pes tsawg lub roj teeb yuav tsum tau txuas rau hauv series kom ze ze rau qhov voltage ntawm cov khoom siv?
Cov khoom siv hluav taws xob / nominal roj teeb voltage = tus naj npawb ntawm cov roj teeb hauv series
14V / 3.7V = 3.78PCS (nws raug nquahu tias tus lej lej tuaj yeem sib npaug lossis nqes, nyob ntawm cov yam ntxwv ntawm cov khoom siv hluav taws xob) Tom qab ntawd peb teeb tsa saum toj no ua 4 txoj hlua ntawm cov roj teeb raws li qhov xwm txheej dav dav.
Nominal voltage yog: 3.7V * 4 = 14.8V.
Ua haujlwm voltage: (3.04 rau 4.24) 12V txog 16.8V
3 、 Cov khoom siv hauv tsev xav tau kev tswj xyuas qhov hluav taws xob, lub roj teeb zoo li cas?
Yog tias yuav tsum muaj kev ruaj ntseg hluav taws xob, muaj ob txoj kev xaiv muaj: a: ntxiv cov kauj ruam-up Circuit Court board ntawm lub roj teeb los muab qhov voltage stabilization; b: ntxiv ib kauj ruam-down Circuit Court board ntawm lub roj teeb los muab qhov voltage stabilization.
Lus Cim: Muaj ob qhov tsis zoo kom ncav cuag qhov muaj zog ruaj khov ua haujlwm:
a: tswv yim / tso zis yuav tsum tau siv cais, tsis tuaj yeem nyob rau hauv tib lub interface tso zis tawm tswv yim;
b: Muaj 5% lub zog poob
