Lithium hlau phosphate roj teeb pobyog nyiam los ntawm ntau tus kiv cua vim nws qhov hnyav dua nyob rau hauv tib lub peev xwm, lub peev xwm ntawm lithium roj teeb yog ib qho tseem ceeb ntawm kev ntsuas ntsuas kev ua tau zoo ntawm lub roj teeb, thaum tso tawm, qhov hluav taws xob ntawm lithium roj teeb yuav maj mam txo nrog qhov kev ua haujlwm ntawm lub roj teeb. hwj chim, thiab muaj ib tug txiav txim siab nqes hav.Cov ntawv no yuav daws tau qhov tsis meej ntawm qhov voltage thiab muaj peev xwm ntawm lithium hlau phosphate roj teeb pob.
1) Lithium hlau phosphate roj teeb pob muaj peev xwm:
Lithium roj teeb pob muaj peev xwm yog ib qho tseem ceeb ntawm kev ntsuas ntsuas kev ua haujlwm ntawm lub roj teeb, nws qhia tias lub zog tso tawm los ntawm lub roj teeb nyob rau hauv qee yam kev mob (kev tawm tus nqi, qhov kub thiab txias, txiav tawm hluav taws xob, thiab lwm yam) (tuaj yeem siv JS-150D rau kev tso tawm. test), uas yog, lub peev xwm ntawm lub roj teeb, feem ntau yog nyob rau hauv lub sij hawm.Lub peev xwm ntawm lithium roj teeb yog muab faib ua lub peev xwm tiag tiag, theoretical muaj peev xwm thiab ntsuas lub peev xwm raws li qhov sib txawv.Cov mis laij lej ntawm cov roj teeb muaj peev xwm C yog C = t0It1dt, thiab cov roj teeb tau muab faib ua qhov zoo thiab tsis zoo electrodes.

2) Voltage ntawm lithium hlau phosphate roj teeb:

Lithium hlau phosphate roj teeb hais txog lithium-ion roj teeb siv lithium hlau phosphate ua cov khoom siv cathode.Cov ntaub ntawv cathode ntawm lithium ion roj teeb feem ntau suav nrog lithium cobalt oxide, lithium manganese oxide, lithium nickel acid, ternary cov ntaub ntawv, lithium hlau phosphate thiab lwm yam. .
Lub charger voltage ntawm lithium hlau phosphate roj teeb pob yuav tsum tau teem rau ntawm 3.65v, nominal voltage 3.2v, lub siab tshaj plaws them voltage yuav ua tau 20% siab tshaj lub nominal voltage, tab sis lub voltage siab dhau mus ua puas lub roj teeb, 3.6v voltage yog qis dua qhov ntsuas no, tsis muaj overcharge.Lithium roj teeb pob yog tias teeb tsa qhov tsawg kawg nkaus 3.0v yuav tsum tau them, ces 3.4v tshaj qhov tsawg kawg nkaus 0.4v, 0.6v tshaj 0.6 v tuaj yeem tso tawm ib nrab ntawm lub zog, uas yog hais, txhua tus nqi, ntau tshaj 3.4v lub sijhawm siv, vim tias lub sijhawm siv roj teeb, yog li lub neej nce ib nrab, yog li thaum tsis muaj kev puas tsuaj rau lub roj teeb, ua kom cov roj teeb muaj zog, yuav ua rau cov roj teeb lithium nce ntxiv.

3) Dab tsi yog qhov kev sib raug zoo ntawm pob hluav taws xob thiab lub peev xwm ntawm lithium hlau phosphate roj teeb pob?
Feem ntau hais lus, qhov siab dua tus nqi thiab tawm qhov hluav taws xob ntawm lithium hlau phosphate roj teeb pob, nws lub peev xwm ntau dua.Qhov kev them nyiaj thiab tawm hluav taws xob ntawm lithium roj teeb ntawm cov khoom sib txawv yog txawv, thiab qhov qis tshaj yog lithium hlau phosphate roj teeb.As lub peev xwm. txo qis, qhov voltage txo, thiab lub peev xwm me me thaum qhov voltage qis dua qhov ntsuas.
1. Rau tib lub roj teeb, nrog tib lub peev xwm seem, tus nqi hluav taws xob sib txawv vim qhov loj ntawm qhov paug tawm tam sim no.Qhov siab dua qhov tso tawm tam sim no, qhov qis dua qhov voltage.Thaum tsis muaj qhov tam sim no, qhov hluav taws xob siab tshaj tam sim no. .
2. Qhov cuam tshuam ntawm ambient kub ntawm lithium roj teeb pob voltage.Qhov ntsuas kub qis dua, lub roj teeb hluav taws xob qis dua ntawm tib lub peev xwm.
3. Qhov cuam tshuam ntawm lub voj voog ntawm lub roj teeb tawm platform.Raws li lub voj voog mus, qhov tso tawm platform ntawm lithium-ion roj teeb zoo li deteriorate.Lub paug platform txo.Yog li lub peev xwm sawv cev los ntawm tib qhov hluav taws xob kuj hloov raws li.
4. Cov chaw tsim khoom sib txawv, muaj peev xwm sib txawv ntawm lithium ion roj teeb, lawv cov pa tawm sib txawv me ntsis.
5. Lub platform tso tawm ntawm cov khoom siv hluav taws xob sib txawv yog qhov sib txawv heev.Cov lithium cobalt thiab manganese lithium paug platforms txawv kiag li.
Tag nrho cov no yuav ua rau muaj kev hloov pauv thiab qhov sib txawv ntawm qhov voltage, ua rau lub peev xwm ntawm lithium hlau phosphate roj teeb pob zaub tsis ruaj khov.

Lithium roj teeb muaj peev xwm hais txog qhov loj ntawm lub roj teeb cia lub zog.Qhov voltage ntawm lithium hlau phosphate roj teeb pob tau poob qis thaum lub sijhawm tso tawm, xws li lub roj teeb 3.6v, 19ah, 19ah muaj peev xwm tsis muab tso rau 0v, tab sis 2. ob peb los yog 3. Thaum twg, lub peev xwm tso tawm yog 19ah, yog muab tso rau 0v, lub peev xwm yuav yog me ntsis ntau tshaj 19, ib yam nkaus thiab, yuav ua rau lub neej ntawm lub roj teeb.
