1. Direct charge tiv thaiv point voltage: Direct charge kuj hu ua thaum muaj xwm ceev them, uas belongs rau ceev ceev.Feem ntau, thaum lub roj teeb voltage tsawg, lub roj teeb tau them nrog cov tam sim no siab thiab kuj muaj qhov hluav taws xob siab.Txawm li cas los xij, muaj qhov taw tes tswj, tseem hu ua kev tiv thaiv Lub ntsiab lus yog tus nqi hauv cov lus saum toj no.Thaum lub roj teeb lub davhlau ya nyob twg voltage siab dua li qhov kev tiv thaiv no thaum them nyiaj, qhov kev them nyiaj ncaj qha yuav tsum raug tso tseg.Qhov hluav taws xob tiv thaiv hluav taws xob ncaj qha feem ntau kuj yog qhov "overcharge tiv thaiv point" voltage, thiab lub roj teeb qhov hluav taws xob tsis tuaj yeem siab tshaj qhov tiv thaiv no thaum them nyiaj, txwv tsis pub nws yuav ua rau overcharging thiab puas lub roj teeb.
2. Kev sib npaug ntawm tus nqi tswj qhov hluav taws xob: Tom qab tus nqi ncaj qha ua tiav, lub roj teeb feem ntau yuav raug tso tseg rau lub sijhawm los ntawm tus nqi-tso tawm tswj kom tso cai rau nws qhov hluav taws xob poob qis.Thaum nws poob rau qhov "rov qab voltage", nws yuav nkag mus rau hauv lub xeev tus nqi sib npaug.Vim li cas thiaj tsim vaj huam sib luag?Ntawd yog, tom qab kev them nyiaj ncaj qha ua tiav, tej zaum yuav muaj cov roj teeb ntawm tus kheej "lag tom qab" (lub davhlau ya nyob twg voltage kuj tsawg).Txhawm rau rub cov tib neeg cov molecules rov qab thiab ua kom tag nrho cov roj teeb lub davhlau ya nyob twg voltages tsis sib xws, nws yog ib qho tsim nyog yuav tsum ua kom muaj qhov hluav taws xob siab nrog qhov nruab nrab voltage.Tom qab ntawd them nws rau ib lub sijhawm luv luv, nws tuaj yeem pom tias qhov kev sib npaug ntawm tus nqi, uas yog, "tus nqi sib npaug".Lub sijhawm them nyiaj sib npaug yuav tsum tsis txhob ntev dhau, feem ntau yog ob peb feeb mus rau kaum feeb, yog tias lub sijhawm teem sijhawm ntev dhau lawm, nws yuav muaj kev phom sij.Rau ib qho me me nruab nrog ib lossis ob lub roj teeb, kev them nyiaj sib npaug yog qhov tseem ceeb me ntsis.Yog li ntawd, txoj kev teeb pom kev zoo feem ntau tsis muaj qhov sib npaug, tab sis tsuas yog ob theem.
3. Float charge point voltage: Feem ntau, tom qab tus nqi sib npaug ua tiav, lub roj teeb kuj tseem tso tseg rau lub sijhawm, kom lub davhlau ya nyob twg qhov hluav taws xob poob qis, thiab thaum nws poob mus rau "kev tswj xyuas voltage" taw tes, nws nkag mus rau lub float charge state.Tam sim no, PWM tau siv.(ob leeg pulse width modulation) txoj kev, zoo ib yam li "trickle charging" (uas yog, me me tam sim no them), them me ntsis thaum lub roj teeb voltage tsawg, thiab them me ntsis thaum nws qis, ib qho los ntawm ib qho los tiv thaiv cov roj teeb kub los ntawm kev txuas ntxiv nce siab, uas yog qhov zoo heev rau lub roj teeb, vim tias qhov kub thiab txias ntawm lub roj teeb muaj kev cuam tshuam zoo rau kev them nqi thiab tawm.Qhov tseeb, PWM txoj kev yog tsim los kom ruaj khov lub roj teeb lub davhlau ya nyob twg voltage, thiab txo cov roj teeb them tam sim no los ntawm kev kho cov mem tes dav.Qhov no yog ib tug scientific charging tswj system.Tshwj xeeb, nyob rau theem tom ntej ntawm kev them nyiaj, thaum lub peev xwm seem (SOC) ntawm lub roj teeb yog> 80%, lub them tam sim no yuav tsum raug txo kom tsis txhob muaj cov pa tawm ntau dhau (oxygen, hydrogen thiab acid gas) vim yog overcharging.
4. Termination voltage ntawm over-discharge tiv thaiv: Qhov no kuj yooj yim to taub.Qhov tso tawm ntawm lub roj teeb tsis tuaj yeem qis dua qhov nqi no, uas yog lub teb chaws tus qauv.Txawm hais tias cov tuam txhab roj teeb kuj muaj lawv tus kheej cov kev tiv thaiv (cov qauv lag luam lossis cov qauv kev lag luam), lawv tseem yuav tsum tau txav mus ze rau lub teb chaws tus qauv thaum kawg.Nws yuav tsum tau muab sau tseg tias, rau lub hom phiaj ntawm kev nyab xeeb, feem ntau 0.3v yog artificially ntxiv rau lub over-discharge tiv thaiv point voltage ntawm lub 12V roj teeb raws li kub them los yog xoom-point drift kho ntawm lub tswj Circuit Court, thiaj li hais tias lub over-discharge. Kev tiv thaiv taw tes voltage ntawm 12V roj teeb yog: 11.10v, tom qab ntawd Kev tiv thaiv tshaj tawm qhov hluav taws xob ntawm 24V system yog 22.20V.
