Xaiv txoj cai lithium roj teeb yog qhov tseem ceeb rau kev ua tau zoo, kev nyab xeeb, thiab kev muaj peev xwm ntawm koj cov khoom. Txawm hais tias koj yog tus kws ua choj lossis kev nkag siab txog tus kws tshaj lij, nkag siab yuav ua li cas paub qhov sib txawv ntawm cov xov tooj ntawm ib qho yog qhov tseem ceeb.
Thaum kev soj ntsuam siab tshaj plaws yog qhov zoo tshaj plaws rau cov kws tshaj lij, koj tuaj yeem xaiv tus kws ntsuam xyuas thawj zaug uas yog kev tsom mus rau cov chaw tseem ceeb no:
1. Cov Chaw Tsim Tshuaj & Lub Neej
Qhov taw qhia ib qho loj tshaj plaws ntawm kev ua tau zoo yog lub hom. Txhua zaus yuav tsum tau lub hlwb los ntawm lub koob npe nrov, zoo -}}}} noob manufacturers.
Top Tier (Tier 1): Companies like CATL, LG Energy Solution, Panasonic/Sanyo, Samsung SDI, and SK Innovation. Cov hom no tau nqis peev ntau hauv R & D, tswj hwm kev zoo, thiab xwm yeem.
Ceev faj: Yuav tsum tau ceev faj heev ntawm cov hlwb uas tsis muaj lub cim muaj peev xwm tshaj tawm (piv txwv li 18650 cell muaj peev xwm ua tau), lossis tus nqi uas zoo li muaj tseeb. Cov no feem ntau siv tau, cuav, lossis b- bads nrog cov kev pheej hmoo loj.
2. Cov Ntsiab Lus Tseem Ceeb & Ntaub Ntawv
Tus neeg xa khoom tau muab cov npe nrov yuav muab cov ntaub ntawv ntxaws ntxaws datasheets. Scrutinize cov ntaub ntawv no:
Kev muaj peev xwm ntsuas (Ah lossis Mah): Puas yog tus lav muaj peev xwm ua kom haum nrog lub cev ntawm lub cev? (xws li, tus qauv 21700 ntawm tes yog feem ntau ntawm 4000-5000mah).
Nominal voltage: feem ntau 3.6v lossis 3.7v rau feem ntau li one {2} ion chemistries (zoo li NMC).
Lub neej voj voog: Tus naj npawb ntawm cov nqi / kev tawm mus los ua ntej lub cell tuaj yeem yauv ua haujlwm rau cov feem pua tshwj xeeb (feem ntau 80% ntawm thawj). Siab - zoo} zoo hlwb muaj {}} cmles, nrog cov hwm tshaj 1000.
Sab hauv kev tiv thaiv (IR): Kev tiv thaiv sab hauv txhais tau txhais tau tias lub xov tooj ntawm tes tuaj yeem xa cov dej siab dua nrog cov cua kub tsawg dua. Qhov no yog ib qho tseem ceeb metric rau cov cuab yeej siv hluav taws xob thiab EVS. Qhov no yuav tsum muaj kev ntsuas kev tshwj xeeb los ntsuas.
3. Kev Ntsuam Xyuas Kev Pom Zoo
Kev tshuaj ntsuam lub cev tuaj yeem qhia ntau qhov flaws:
Labelling & luam ntawv: Saib kom huv si, laser -} ovched, lossis cov ntawv luam tawm khov kho thiab cov kev qhia tshwj xeeb. Smudged, nkhaus, lossis cov ntawv luam tsis zoo yog tus chij liab.
Qhov loj me & qhov hnyav: hnyav ntawm cell. Lub cev tsis xwm yeem feem ntau qhia tias cov khoom siv sab hauv lossis lub tsho tam sim no, teeb tsa qhov muaj peev xwm qis dua lossis ua haujlwm tsis zoo. Ntsuas cov qhov ntev los xyuas kom meej tias lawv tau ua raws cov qauv.
Terminals (ncej): Qhov kev sim zoo thiab tsis zoo thiab tsis zoo, thiab ua los ntawm cov khoom raug (piv txwv, tooj kuj tsis zoo). Zam kev cell nrog cov cim ntawm khawb, cov cim cam, lossis xeb, uas qhia txog kev siv yav dhau los lossis chaw khaws khoom tsis zoo.
Casing: tus hlau casing yuav tsum tau txig txig cylindrical nrog tsis muaj pob, dents, lossis khawb. Tej yam deformity yog kev phom sij muaj kev nyab xeeb loj.
4. Kev sim tshuaj ntsuam (yog tias ua tau)
Yog tias koj muaj cov cuab yeej yooj yim, koj tuaj yeem ua cov kev ntsuam xyuas yooj yim:
Kev Kuaj Peev: Siv lub peev xwm muaj roj teeb muaj peev xwm them thiab tawm ntawm tes ntawm tus qauv. Nov yog tib txoj kev tseeb los txheeb xyuas yog tias nws ua tau raws li nws cov paj nruag Mah thov. Cov hlwb cuav feem ntau ntsuas ntawm 50% lossis tsawg dua ntawm lawv lub peev xwm teev.
Voltage xyuas: Ib lub xov tooj ntawm tes tshiab yuav tsum tuaj txog ntawm qhov chaw cia khoom ntawm 3.6V. Ib qho hluav taws xob tseem ceeb dua (piv txwv li, 4.2V 满电) lossis qis dua (<3.0V) qhia tias tsis zoo siv rau hauv lub txee rau xyoo. Ib qho hluav taws xob hauv qab no 2.5v feem ntau txhais tau tias yog lub cell sib tsoo thiab puas tas mus li.
5. Kev ruaj ntseg ntawv pov thawj
Nrhiav cov pov thawj ntawm cov qauv kev nyab xeeb kev nyab xeeb ua raws cai. Cov ntawv pov thawj tseem ceeb muaj xws li:
UL 1642 (Txheem rau cov roj teeb lithium)
IEC 62133 (Kev Ruaj Ntseg Kev Nyab Xeeb Kev Nyab Xeeb rau Cov Khoom Siv Portable)
UN / DOT 38.3 (Kev Ntsuas Kev Nyab Xeeb Kev Nyab Xeeb)
