Thaum them lub roj teeb lithium-ion, qhov them tam sim no thiab them qhov hluav taws xob yuav tsum tau tswj raws li lub sijhawm ua ntu zus.Yog li ntawd, kev tshawb fawb ua hauj lwm ntawm lub hwj chim lithium-ion roj teeb charger yuav tsum tau nqa tawm maj mam nyob rau hauv lub hauv paus ntawm kom meej meej grasing nws them thiab tawm cov yam ntxwv, uas yog, lub ntsiab yam tseem ceeb cuam tshuam rau kev them nqi ntawm lithium-ion roj teeb: voltage thiab tam sim no.
1. Qhov hluav taws xob.Lub nominal voltage ntawm lithium-ion roj teeb feem ntau yog 3.6V lossis 3.7V (nyob ntawm cov chaw tsim khoom).Tus nqi txiav tawm voltage (tseem hu ua floating voltage lossis floating voltage) feem ntau yog 4.1V, 4.2V, thiab lwm yam, nyob ntawm seb cov khoom siv electrode.Feem ntau, qhov kev txiav tawm hluav taws xob yog 4.2V thaum cov khoom siv tsis zoo electrode yog graphite, thiab qhov txiav tawm voltage yog 4.1V thaum cov khoom tsis zoo electrode yog carbon.Rau tib lub roj teeb, txawm tias qhov pib voltage sib txawv thaum them, thaum lub roj teeb muaj peev xwm ncav cuag 100%, qhov kawg voltage yuav ncav cuag tib theem.Nyob rau hauv cov txheej txheem ntawm kev them lub roj teeb lithium-ion, yog tias qhov hluav taws xob siab dhau lawm, cov cua kub ntau yuav raug tsim tawm hauv lub roj teeb, uas yuav ua rau cov qauv hluav taws xob zoo ntawm lub roj teeb puas lossis ua rau luv luv.Yog li ntawd, nws yog ib qho tsim nyog los saib xyuas qhov kev them nqi hluav taws xob ntawm lub roj teeb thaum siv lub roj teeb los tswj qhov hluav taws xob nyob rau hauv qhov kev tso cai voltage ntau.
2. Tam sim no.Cov txheej txheem them nyiaj yuav tsum tau tswj cov nqi them tam sim no.Kev them nyiaj tam sim no ntawm lub roj teeb yog txiav txim siab los ntawm lub peev xwm nominal ntawm lub roj teeb.Lub cim muaj peev xwm nominal yog C, thiab chav tsev yog "Ah".Txoj kev suav yog: C = IT (1-1) Hauv cov qauv, Kuv yog qhov tso tawm tam sim no tsis tu ncua, thiab T yog lub sijhawm tso tawm.Piv txwv li, txhawm rau them lub roj teeb nrog lub peev xwm ntawm 50Ah nrog rau qhov tam sim no ntawm 50A, nws yuav siv sijhawm 1 teev kom them lub roj teeb tag nrho.Lub sijhawm no, tus nqi them yog 1C, thiab cov nqi them feem ntau yog nyob nruab nrab ntawm 0.1C thiab 1C.Feem ntau hais lus, cov txheej txheem them nyiaj tau muab faib ua peb hom: them qeeb (tseem hu ua trickle charging), them ceev ceev thiab ultra-high-speed charging raws li cov nqi sib txawv.Tam sim no ntawm kev them nqi qeeb yog nruab nrab ntawm 0.1C thiab 0.2C;qhov them tam sim no ntawm kev them ceev ceev yog ntau dua 0.2C tab sis tsawg dua 0.8C;qhov them tam sim no ntawm kev them nyiaj ceev ceev yog siab dua 0.8C.Txij li thaum lub roj teeb muaj ib qho kev tiv thaiv sab hauv, nws cov cua sov sab hauv muaj feem xyuam rau qhov tam sim no.Thaum lub sijhawm ua haujlwm tam sim no ntawm lub roj teeb loj dhau lawm, nws cov cua sov yuav ua rau qhov kub thiab txias ntawm lub roj teeb kom siab tshaj tus nqi ib txwm, uas yuav cuam tshuam rau kev nyab xeeb ntawm lub roj teeb thiab txawm tias ua rau tawg.Nyob rau theem pib ntawm kev them nyiaj, txawm tias lub roj teeb tau tso tawm ntau dhau, nws tsis tuaj yeem raug them ncaj qha nrog cov tam sim no loj.Thiab raws li kev them nyiaj txuas ntxiv, lub roj teeb lub peev xwm lees txais tam sim no raug txo qis.Yog li ntawd, nyob rau hauv tus txheej txheem ntawm kev them lub roj teeb, lub them tam sim no yuav tsum tau tswj raws li lub xeev tshwj xeeb ntawm lub roj teeb.
