1. Taw qhia txog lithium-ion roj teeb
1.1 Lub Xeev Tus Nqi (SOC)
Lub xeev ntawm tus nqi tuaj yeem txhais tau tias yog lub xeev ntawm cov hluav taws xob muaj hluav taws xob hauv lub roj teeb, feem ntau qhia raws li feem pua.Vim hais tias cov hluav taws xob muaj hluav taws xob sib txawv nrog rau kev them nqi thiab kev tso tawm tam sim no, qhov kub thiab txias tshwm sim, lub ntsiab lus ntawm lub xeev tus nqi kuj tau muab faib ua ob hom: Absolute State-Of-Charge (ASOC) thiab txheeb ze State-Of-Charge (RSOC) .
Feem ntau, qhov sib txawv ntawm lub xeev tus nqi yog 0% - 100%, thaum nws yog 100% thaum lub roj teeb tau them tag nrho thiab 0% thaum nws tawm tag nrho.Qhov tseeb ntawm tus nqi yog tus nqi siv tau suav raws li tus nqi tsim khoom ruaj khov thaum lub roj teeb tsim.Lub xeev tag nrho ntawm tus nqi ntawm lub roj teeb tshiab yog 100%;Txawm hais tias lub roj teeb laus tau them tag nrho, nws tsis tuaj yeem ncav cuag 100% raws li kev them nqi sib txawv thiab kev tso tawm.
Daim duab hauv qab no qhia txog kev sib raug zoo ntawm qhov hluav taws xob thiab lub roj teeb muaj peev xwm ntawm qhov sib txawv ntawm qhov paug tawm.Qhov siab dua tus nqi tso tawm, lub roj teeb muaj peev xwm qis dua.Thaum qhov kub thiab txias qis, lub roj teeb muaj peev xwm kuj yuav txo.

1.2 Max Charging Voltage
Qhov siab tshaj plaws them voltage muaj feem xyuam rau cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv ntawm lub roj teeb.Kev them nqi hluav taws xob ntawm lithium roj teeb feem ntau yog 4.2V thiab 4.35V, thiab cov nqi hluav taws xob ntawm cathode thiab anode cov ntaub ntawv yuav txawv.
1.3 Them tag nrho
Thaum qhov sib txawv ntawm lub roj teeb hluav taws xob thiab qhov siab tshaj plaws them hluav taws xob tsawg dua 100mV thiab qhov them tam sim no raug txo rau C / 10, lub roj teeb tuaj yeem suav tias yog them tag nrho.Cov xwm txheej them tag nrho txawv nrog cov yam ntxwv ntawm lub roj teeb.
Daim duab hauv qab no qhia tau hais tias ib txwm lithium roj teeb them tus yam ntxwv nkhaus.Thaum lub roj teeb hluav taws xob sib npaug rau qhov siab tshaj plaws them hluav taws xob thiab qhov them tam sim no raug txo mus rau C / 10, lub roj teeb tau suav tias yuav tsum tau them tag nrho.

1.4 Yam tsawg kawg nkaus tawm voltage
Qhov tsawg kawg nkaus tawm voltage tuaj yeem txhais tau los ntawm kev txiav tawm qhov hluav taws xob, uas feem ntau yog qhov hluav taws xob thaum lub xeev them nqi yog 0%.Tus nqi hluav taws xob no tsis yog tus nqi ruaj khov, tab sis hloov nrog kev thauj khoom, qhov kub thiab txias, qib kev laus lossis lwm yam.
1.5 Tso tawm tag nrho
Thaum lub roj teeb voltage tsawg dua los yog sib npaug rau qhov tsawg kawg nkaus tawm voltage, nws tuaj yeem hu ua tiav qhov paug tawm.
1.6 Tus nqi them thiab tso tawm (C-Rate)
Tus nqi them-tso tawm yog tus sawv cev ntawm tus nqi-tso tawm tam sim no txheeb ze rau lub peev xwm roj teeb.Piv txwv li, yog tias koj siv 1C tso tawm rau ib teev, qhov zoo tshaj plaws, lub roj teeb yuav tawm tag nrho.Cov nqi sib txawv ntawm cov nqi them tawm yuav ua rau muaj peev xwm siv tau sib txawv.Feem ntau, qhov siab dua tus nqi-tso tawm, qhov tsawg dua qhov muaj peev xwm.
1.7 Lub neej voj voog
Tus naj npawb ntawm cov voj voog yog hais txog tus naj npawb ntawm kev ua tiav thiab tso tawm ntawm lub roj teeb, uas tuaj yeem kwv yees los ntawm qhov tseeb tso tawm thiab lub peev xwm tsim.Thaum lub peev xwm tso tawm sib npaug sib npaug ntawm qhov tsim muaj peev xwm, tus naj npawb ntawm cov voj voog yuav tsum yog ib qho.Feem ntau, tom qab 500 lub sij hawm them-tso tawm, lub peev xwm ntawm lub roj teeb tag nrho yuav txo qis los ntawm 10% ~ 20%.

1.8 Tus kheej tso tawm
Kev tso tawm tus kheej ntawm tag nrho cov roj teeb yuav nce nrog qhov kub thiab txias.Kev tso tawm tus kheej yog qhov pib tsis yog kev tsim khoom, tab sis cov yam ntxwv ntawm lub roj teeb nws tus kheej.Txawm li cas los xij, kev kho tsis raug hauv cov txheej txheem tsim khoom kuj tseem yuav ua rau muaj kev tawm ntawm tus kheej.Feem ntau, tus kheej tawm tus nqi yuav raug muab ob npaug rau thaum lub roj teeb kub nce 10 ° C. Lub peev xwm tawm ntawm tus kheej ntawm lithium-ion roj teeb yog li 1-2% ib hlis, thaum lub roj teeb ntawm ntau yam nickel-based roj teeb yog 10- 15% ib hlis.
