Yuav ua li cas txiav txim siab seb lub lithium ion roj teeb tsis zoo?
Aug 11, 2020
Ua ntej tshaj, xyuas seb hom roj teeb lithium yog dab tsi thiab sim nrhiav kom paub cov chaw tsim tshuaj paus' s kev qhia tshwj xeeb. Qhov no yog qhov zoo tshaj plaws kom pom qhov ua tau zoo ntawm ib lub roj teeb tshwj xeeb hais txog qhov txwv voltage, tam sim no, sab hauv, thiab lwm yam.
Tom qab ntawd-sim ntsuas (yog tias koj muaj cov cuab yeej lossis paub yuav ua li cas nws) qhov ntsuas hluav taws xob, kev tiv taus thiab kev ua tau zoo. Sib piv cov txiaj ntsig no nrog lub khw tsim khoom' s tshwj xeeb. Match? Tseem tshuav deb? Nws' s uas yooj yim.
Yog tias koj ntsuas ntau dua lossis tsawg dua raws li cov chaw tsim khoom' s thov, nws yuav tsum ua kom zoo.
Yog tias tsis yog qhov no, nws yuav muaj kev nyab xeeb dua kom muab cov roj teeb no pov tseg. Nws tsis tsim nyog qhov kev pheej hmoo ntawm hluav taws lossis zoo sib xws.
Yog tias cov chaw tsim khoom' s cov ntaub ntawv tsis muaj, sim sim seb hom lithium roj teeb (roj teeb) yog dab tsi, thiab tom qab ntawd ntsuas raws nws. Muaj ntau ntau yam sib txawv (peb lub roj teeb roj teeb uas siv tau ntau tshaj yog>> nominal voltage 3.6V lithium ion roj teeb, 3.2V LiPO4 roj teeb, roj teeb 2.4V LTO, thiab lwm yam)
Txhawm rau txiav txim siab seb lub roj teeb lithium tsis zoo, qhov yooj yim tshaj plaws yog kom nws kom them tag nrho lub xeev (ze rau 100%), thiab tom qab ntawd ntsuas qhov ntsuas hluav taws xob poob thaum tawm mus.
Piv txwv: 18650 roj teeb, muaj peev xwm ntsuas tau 2600mAh, hluav taws xob nominal 3.6V, them tag nrho 4.2V, txiav tawm txiav tawm tsis pub tshaj 2.75V. Them kom txog 4.1-4.2V, tom qab ntawd pib tawm nrog 1A tam sim no. Lub sijhawm no, qhov ntsuas qhov ntsuas hluav taws xob yog ntsuas. Nws yuav tsum tsis poob qis dua 4 វ៉ុល. Yog tias nws qis dua 3.9, 3.8 lossis qis dua, lub roj teeb ua haujlwm qub thiab tuaj yeem ntim txhua lub sijhawm.
Ntxiv rau, yog tias lub roj teeb no (raws li tau piav qhia saum toj no) overheated thaum them nyiaj / tso tawm 1A, nws tsis zoo siv nws dua, nws yog qhov zoo tshaj rau kev muab pov tseg.
Thiab qhov ceev ntawm nws tus kheej tso tawm tuaj yeem qhia koj tias lub roj teeb ua tau zoo lossis tsis zoo. Tau them tag nrho thiab muab tso rau qhov chaw zoo. Nyeem cov voltage tom qab ob peb teev. sau ntawv. Tom qab ib hlis (lossis txawm ob hlis), ntsuas lub ntsuas hluav taws xob dua. Qhov sib txawv los ntawm thawj ntsuas tus nqi yuav tsum tsis txhob ntau tshaj 10% ntawm tag nrho tus nqi. Yog nws tsis zoo.
