Tsis yog nws amazing npaum li cas cov ntaub ntawv ib qho yooj yim voltage nyeem ntawv tuaj yeem muab thaum koj paub txhais nws li cas?
Tab sis ntawm no yog ib lo lus nug kom xav txog: Yuav ua li cas voltage nyeem ntawv hloov nyob rau hauv load piv rau so? Thiab koj tuaj yeem suav rau qhov no hauv koj lub tswv yim tswj roj teeb li cas?
Los ntawm kev paub txog kev siv LiFePO4 cov kab kos hluav taws xob, koj tsis yog nyeem cov lej xwb - koj tab tom qhib cov lus zais ntawm koj lub roj teeb. Qhov kev paub no txhawb nqa koj kom ua tau zoo tshaj plaws, ua kom lub neej ntev, thiab tau txais txiaj ntsig zoo tshaj plaws ntawm koj lub zog cia.
Voltage cuam tshuam li cas LiFePO4 Battery Performance?
Voltage ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov kev ua tau ntawm LITPO4 roj teeb, kev tawm dag zog, cov yam ntxwv hluav taws xob, thiab kev nyab xeeb.
Ntsuas roj teeb Voltage
Kev ntsuas roj teeb voltage feem ntau yog siv lub voltmeter. Nov yog cov lus qhia dav dav txog kev ntsuas roj teeb voltage:
1. Xaiv qhov tsim nyog Voltmeter: xyuas kom meej tias lub voltmeter tuaj yeem ntsuas qhov xav tau ntawm lub roj teeb.
2. Tig lub Circuit Court: Yog hais tias lub roj teeb yog ib feem ntawm lub Circuit Court loj, hloov lub Circuit Court ua ntej ntsuas.
3. Txuas lub Voltmeter: Txuas lub voltmeter rau lub roj teeb terminals. Cov hlau lead liab txuas rau lub davhlau ya nyob twg zoo, thiab cov hlau lead dub txuas mus rau qhov tsis zoo.
4. Nyeem qhov Voltage: Thaum txuas, lub voltmeter yuav tso saib lub roj teeb qhov hluav taws xob.
5. Txhais Kev Nyeem Ntawv: Ua tib zoo nyeem cov ntawv nyeem kom txiav txim siab lub roj teeb voltage.

Nkag siab txog cov yam ntxwv ntawm qhov hluav taws xob ntawm LiFePO4 roj teeb yog qhov tseem ceeb rau lawv txoj kev siv tau zoo hauv ntau hom kev siv. Los ntawm kev xa mus rau LiFePO4 voltage daim ntawv qhia, koj tuaj yeem txiav txim siab paub txog kev them nqi, kev tso tawm, thiab kev tswj hwm roj teeb tag nrho, thaum kawg ua kom tiav qhov kev ua tau zoo thiab kev ua neej ntawm cov kev daws teeb meem siab heev.
Hauv kev xaus, daim ntawv qhia hluav taws xob ua haujlwm yog ib qho cuab yeej tseem ceeb rau cov kws tsim khoom, cov neeg koom ua ke, thiab cov neeg siv kawg, muab kev nkag siab tseem ceeb rau kev coj tus cwj pwm ntawm LiFePO4 roj teeb thiab ua kom zoo tshaj plaws ntawm lub zog cia rau ntau yam kev siv. Los ntawm kev ua raws li cov theem kev pom zoo thiab cov txheej txheem them nyiaj kom raug, koj tuaj yeem ua kom lub neej ntev thiab kev ua haujlwm ntawm koj LiFePO4 roj teeb.
FAQ Txog LiFePO4 Roj teeb Voltage Chart
Q: Kuv yuav nyeem LiFePO4 roj teeb voltage li cas?
A: Txhawm rau nyeem LiFePO4 roj teeb voltage daim ntawv qhia, pib los ntawm kev txheeb xyuas X thiab Y axes. X-axis feem ntau sawv cev rau lub roj teeb lub xeev ntawm kev them nqi (SoC) raws li feem pua, thaum Y-axis qhia qhov voltage. Nrhiav qhov nkhaus uas sawv cev rau lub roj teeb tawm lossis lub voj voog them. Daim ntawv qhia yuav qhia qhov voltage hloov li cas thaum lub roj teeb tawm los yog tsub nqi. Ua tib zoo mloog cov ntsiab lus tseem ceeb xws li nominal voltage (feem ntau nyob ib ncig ntawm 3.2V ib lub xov tooj ntawm tes) thiab qhov voltage ntawm ntau qib SoC. Nco ntsoov tias cov roj teeb LiFePO4 muaj qhov sib tw voltage nkhaus piv rau lwm cov chemistry, uas txhais tau hais tias qhov hluav taws xob nyob twj ywm ruaj khov nyob rau ntau qhov SOC.
Q: Dab tsi yog qhov zoo tagnrho voltage ntau rau LiFePO4 roj teeb?
A: Qhov zoo tshaj plaws voltage ntau rau LiFePO4 roj teeb nyob ntawm seb muaj pes tsawg lub hlwb hauv series. Rau ib lub xov tooj ntawm tes, qhov kev ua haujlwm nyab xeeb feem ntau yog nruab nrab ntawm 2.5V (tag nrho tawm) thiab 3.65V (tag nrho them). Rau 4-cell roj teeb pob (12V nominal), qhov ntau yuav yog 10V txog 14.6V. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov roj teeb LiFePO4 muaj qhov nkhaus voltage nkhaus heev, txhais tau hais tias lawv tuav qhov voltage tsis tu ncua (nyob ib ncig ntawm 3.2V ib lub xov tooj) rau feem ntau ntawm lawv lub voj voog tawm. Txhawm rau ua kom lub roj teeb ua haujlwm siab tshaj plaws, nws raug pom zoo kom ua kom lub xeev them nqi nruab nrab ntawm 20% thiab 80%, uas sib haum mus rau qhov qis dua me ntsis.
Q: Qhov ntsuas kub li cas rau LiFePO4 roj teeb voltage?
A: Kub muaj feem cuam tshuam rau LiFePO4 roj teeb voltage thiab kev ua haujlwm. Feem ntau, raws li qhov kub thiab txias, roj teeb voltage thiab muaj peev xwm txo qis me ntsis, thaum lub zog sab hauv kuj nce. Hloov pauv, qhov kub siab dua tuaj yeem ua rau muaj qhov hluav taws xob siab dua me ntsis tab sis tuaj yeem txo cov roj teeb lub neej yog tias ntau dhau. LiFePO4 roj teeb ua tau zoo tshaj plaws ntawm 20 ° C thiab 40 ° C (68 ° F txog 104 ° F). Ntawm qhov kub qis heev (qis dua 0 ° C lossis 32 ° F), kev them nyiaj yuav tsum ua tib zoo kom tsis txhob muaj lithium plating. Feem ntau cov kev tswj hwm roj teeb (BMS) kho cov nqi them raws li qhov ntsuas kub kom ntseeg tau tias muaj kev nyab xeeb. Nws yog ib qho tseem ceeb los tham txog cov chaw tsim khoom tshwj xeeb rau qhov ntsuas kub-voltage kev sib raug zoo ntawm koj lub roj teeb LiFePO4 tshwj xeeb.
