  • Txoj kev them nqi thiab kev them nqi ntawm lithium roj teeb yog dab tsi?

    Lithium-ion roj teeb them txoj kev yeej ib txwm ua kom pom tseeb.Kev them nyiaj tsis raug ntawm cov roj teeb lithium-ion tuaj yeem ua rau muaj ntau yam teeb meem kev nyab xeeb.Yog li ntawd, nws yog ib qho tseem ceeb heev los txheeb xyuas txoj kev them nyiaj ntawm lithium roj teeb, thiab nws tseem yog qhov tsim nyog lav rau kev nyab xeeb.Tau kawg, lub lithium roj teeb them yuav tsum siv cov ntawv pov thawj kev nyab xeeb tau teev tseg lithium roj teeb charger.

    1. Meth

    (1) Ua ntej lub roj teeb lithium-ion tawm ntawm lub Hoobkas, cov chaw tsim khoom tau ua haujlwm ua haujlwm thiab them ua ntej, yog li cov roj teeb lithium-ion muaj lub zog seem, thiab cov roj teeb lithium-ion raug them raws li lub sijhawm hloov.Lub sijhawm hloov kho no yuav tsum tau them tag nrho 3 mus rau 5 zaug.tso tawm.

     

    (2) Ua ntej them, lub roj teeb lithium-ion tsis tas yuav tsum tau tso tawm tshwj xeeb.Kev tso tawm tsis raug yuav ua rau lub roj teeb puas.Thaum them nyiaj, sim siv qeeb them thiab txo kom them ceev;lub sijhawm yuav tsum tsis pub tshaj 24 teev.Cov tshuaj lom neeg hauv lub roj teeb yuav ua tiav "ua haujlwm" tom qab peb mus rau tsib lub voj voog them tag nrho kom ua tiav cov txiaj ntsig zoo tshaj plaws.

     

    (3) Thov siv daim ntawv pov thawj charger los yog lub npe nrov charger.Rau cov roj teeb lithium, siv lub charger tshwj xeeb rau cov roj teeb lithium thiab ua raws li cov lus qhia, txwv tsis pub lub roj teeb yuav raug puas los yog txaus ntshai.

     

    (4) Lub roj teeb uas nyuam qhuav yuav yog lithium ion, yog li thawj 3 mus rau 5 zaug ntawm kev them nyiaj feem ntau hu ua lub sijhawm hloov kho, thiab nws yuav tsum tau them rau ntau tshaj 14 teev kom ntseeg tau tias cov haujlwm ntawm lithium ion tau ua tiav.Cov roj teeb lithium-ion tsis muaj kev nco, tab sis muaj zog inertness.Lawv yuav tsum tau ua kom tiav kom ntseeg tau tias qhov ua tau zoo tshaj plaws hauv kev siv yav tom ntej.

     

    (5) Lub roj teeb lithium-ion yuav tsum siv lub charger tshwj xeeb, txwv tsis pub nws yuav tsis ncav cuag lub xeev saturation thiab cuam tshuam rau nws cov kev ua tau zoo.Tom qab them nyiaj, tsis txhob muab tso rau ntawm lub charger rau ntau tshaj 12 teev, thiab cais lub roj teeb ntawm cov khoom siv hluav taws xob hauv lub xov tooj ntawm tes thaum nws tsis siv sijhawm ntev.

    Txoj kev them nqi thiab kev them nqi ntawm lithium roj teeb yog dab tsi?

    2. Txheej txheem

    Cov txheej txheem them nyiaj ntawm lithium-ion roj teeb tuaj yeem muab faib ua peb theem: kev them nyiaj tam sim no tsis tu ncua, qhov them nyiaj tsis tu ncua, thiab kev them nyiaj tsis tu ncua.

     

    Theem 1:Tam sim no rau kev them nyiaj tas li yog nyob nruab nrab ntawm 0.2C thiab 1.0C.Lub lithium-ion roj teeb voltage maj mam nce nrog cov txheej txheem them tam sim no.Feem ntau, qhov voltage teem los ntawm ib leeg-cell li-ion roj teeb yog 4.2V.

     

    Theem 2:kev them nyiaj tam sim no xaus thiab qhov tsis tu ncua voltage them theem pib.Raws li qhov saturation degree ntawm lub xov tooj ntawm tes, cov nqi them tam sim no maj mam txo los ntawm tus nqi siab tshaj plaws raws li cov txheej txheem them nqi txuas ntxiv.Thaum nws txo qis rau 0.01C, qhov kev them nyiaj raug txiav txim siab raug txiav.

     

    Kauj Ruam 3:trickle charging, Thaum lub roj teeb yuav luag tag nrho, Lub them tam sim no tseem txo qis, Thaum nws tsawg dua 10% ntawm cov nqi them tam sim no, LED tig liab mus rau ntsuab, Lub roj teeb pom tau tias yog them tag nrho.
