Hauv kev lag luam ntawm cov roj teeb, qhov kev faib tawm ntawm cov roj teeb zoo yog qhov tseem ceeb rau cov khoom lag luam thiab kev ntseeg tau. Feem ntau, cov roj teeb roj tau muab faib ua Class A, Class B, thiab Class C.
1, A-qib roj teeb cell
A-chav kawm roj teeb hlwb yog hom roj teeb zoo tshaj plaws, nrog cov qauv zoo hauv kev lag luam rau cov khoom siv roj teeb, thev naus laus zis, lub zog cia, ruaj khov them thiab tso tawm, cov lus qhia tshwj xeeb, thiab cov qauv ntsuas kub tsis tu ncua. A-chav kawm roj teeb hlwb feem ntau raug txiav txim ncaj qha los ntawm cov chaw tsim khoom roj teeb los ntawm lub Hoobkas siv cov roj teeb hlwb. Cell manufacturers npaj ntau lawm raws li lub Hoobkas tsim thiab kev muaj peev xwm. Tom qab cov txheej txheem ntawm cov roj teeb ntawm tes ntau lawm, cov roj teeb hlwb thaum kawg tau tsim thiab xa mus rau cov neeg siv khoom. Nws muaj cov yam ntxwv hauv qab no:
1.Muaj peev xwm tuav tau tus nqi:Tom qab ntau lub sij hawm them nqi thiab tawm mus, cov cuab yeej tseem tuaj yeem tuav lub peev xwm siab, ua kom lub roj teeb ntev dua.
2. Tsawg sab hauv tsis kam:Ib qho kev tiv thaiv me me txhais tau hais tias tsawg zog poob thaum lub sij hawm tso tawm, tso cai rau cov khoom siv hluav taws xob ntau dua.
3. Zoo sib xws:A-chav kawm roj teeb hlwb los ntawm tib batch muaj ib tug high degree ntawm sib xws nyob rau hauv tsis xws li muaj peev xwm thiab voltage, uas yog ib qho tseem ceeb rau kev ruaj ntseg thiab kev ruaj ntseg ntawm lub roj teeb pob.
4. Kev nyab xeeb siab:Tom qab kev ntsuas kev nyab xeeb nruj, suav nrog overcharge, overdischarge, luv Circuit Court, compression thiab lwm yam kev sim, nws ua kom ntseeg tau tias kev nyab xeeb yuav tsis tshwm sim nyob rau hauv ntau yam kev siv.
2, B-chav kawm roj teeb cell
Qhov zoo ntawm B-chav roj teeb yog me ntsis qis dua rau A-chav kawm roj teeb. Ntawm cov tuam txhab roj teeb ntawm tes, qhov tsis xws luag ntawm thawj theem tuam txhab tuaj yeem ncav cuag li 2%, thaum thib ob - thiab thib peb cov tuam txhab lag luam yuav ncav cuag 5% -10%. Nws yog precisely vim hais tias ntawm no defect tus nqi uas B-chav kawm roj teeb yog tsim. B-chav kawm roj teeb hlwb tsuas muaj qhov sib txawv me ntsis, lossis lawv qhov ntev, qhov dav, thiab tuab tsis ua raws li qhov yuav tsum tau ua, tab sis lawv qhov kev ua tau zoo tsis txo qis thiab lawv cov nqi pheej yig dua li A-chav kawm roj teeb hlwb. Tsis tas li ntawd, cov roj teeb A-chav feem ntau yog khaws cia hauv cov tsev khaws khoom, thiab yog tias lawv tsis raug xa mus rau 3-6 lub hlis, lawv tseem hu ua B-chav roj teeb. B-chav kawm roj teeb hlwb feem ntau nthuav tawm:
1. Tsawg muaj peev xwm tuav tau tus nqi:Tom qab ntau lub sijhawm them thiab tawm mus, lub peev xwm yuav txo qis rau qee qhov, tab sis nws tseem tuaj yeem ua tau raws li qee qhov kev thov uas tsis xav tau lub roj teeb siab.
2. Me ntsis siab dua internal kuj:Lub zog poob yog qhov siab dua piv rau A-chav kawm roj teeb hlwb, tab sis nws tseem tuaj yeem siv tau rau hauv cov xwm txheej uas yuav tsum tau ua haujlwm tsis dhau.
3. General sib xws:Qhov sib xws ntawm parameters ntawm B-class hlwb nyob rau hauv tib batch tsis zoo li cov A-chav kawm hlwb, tab sis nws tseem nyob rau hauv ib tug ntau npaum li cas.
4. Hais txog kev ruaj ntseg:Tom qab tau txais qee qhov kev ntsuam xyuas kev nyab xeeb, tej zaum yuav muaj qee yam kev pheej hmoo nyob rau hauv qee yam mob hnyav.
3, C-qib roj teeb cell
C-qib roj teeb hlwb yog cov qeb qis tshaj plaws. Cov roj teeb C-qib txawv ntawm A-qib roj teeb nyob rau hauv cov nqe lus ntawm lub zog cia, ruaj khov them thiab tso tawm efficiency, roj teeb cov ntaub ntawv, thev naus laus zis, thiab rov them dua thiab tawm. Yog hais tias B-chav kawm roj teeb cell khaws cia rau hauv lub warehouse rau ntau tshaj 8 lub hlis yam tsis tau xa, nws tuaj yeem hu ua C-class roj teeb cell. Vim lub sij hawm cia ntev ntawm cov roj teeb C-qib, lawv qhov kev ua tau zoo pib poob qis thaum lawv muaj hnub nyoog vim nws tus kheej tawm, plua plav, thiab dej vapor. Nws cov yam ntxwv yog raws li nram no:
1. Tsawg peev tuav tus nqi:Tom qab siv sijhawm luv luv, lub peev xwm yuav txo qis thiab lub roj teeb lub neej yuav luv. C-qib roj teeb hlwb feem ntau tsuas muaj li 50% -60% ntawm kev ua haujlwm ntawm A-chav roj teeb ntawm tib hom, thiab qhov zoo tshaj plaws tuaj yeem ncav cuag 70%.
2. High Internal Resistance:Loj zog poob thiab tsis tshua muaj paug efficiency.
3. Tsis zoo sib xws:Qhov sib txawv ntawm qhov sib txawv yog qhov tseem ceeb thiab tsis haum rau kev tsim cov pob roj teeb.
4. Kev nyab xeeb qis:Tej zaum yuav muaj teeb meem kev nyab xeeb tseem ceeb, xws li kev pheej hmoo ntawm overheating, hluav taws kub, thiab lwm yam xwm txheej.
4, Yuav ua li cas paub qhov txawv A-qib, B-qib, thiab C-qib roj teeb hlwb
1. Kev kuaj muaj peev xwm:Ua cov nqi them thiab tso tawm cov kev sim ntawm cov roj teeb uas siv cov cuab yeej siv roj teeb muaj peev xwm los sib piv lawv cov peev xwm tuav tau. A-chav kawm roj teeb hlwb muaj peev xwm tuav tau siab, thaum C-chav kawm roj teeb hlwb muaj peev xwm tuav tau qis.
2. Internal resistance ntsuas:Siv lub ntsuas ntsuas sab hauv los ntsuas qhov tsis kam sab hauv ntawm lub roj teeb ntawm tes. A-chav kawm roj teeb hlwb muaj qhov tsis zoo sab hauv, thaum C-chav kawm roj teeb hlwb muaj kev tiv thaiv sab hauv.
3. Kev ntsuas qhov sib xws:Sib piv qhov tsis sib xws ntawm cov hlwb los ntawm tib lub batch, suav nrog lub peev xwm, qhov hluav taws xob, thiab lwm yam. A-chav roj teeb hlwb muaj qhov sib xws zoo, thaum C-chav roj teeb hlwb muaj qhov tsis zoo.
4. Kev ntsuam xyuas kev nyab xeeb:Ua ntau yam kev ntsuam xyuas kev nyab xeeb, xws li overcharge, overdischarging, short circuits, thiab lwm yam. A-class roj teeb ua tau zoo nyob rau hauv kev ntsuam xyuas kev nyab xeeb, thaum C-class roj teeb yuav tsis dhau ib co kev ntsuam xyuas kev nyab xeeb.
5.Original manufacturers daim ntawv xeem:Daim ntawv tshaj tawm cov ntaub ntawv yuav tsum suav nrog cov kev tiv thaiv sab hauv, qhov hluav taws xob, lub peev xwm, thiab cov khoom lag luam (feem ntau tib yam li cov ntaub ntawv ntawm QR code) ntawm txhua lub roj teeb ntawm tes. Yog tias tsis muaj cov ntaub ntawv zoo li no, nws muaj feem ntau tias nws yog B-chav kawm roj teeb ntawm tes.
Muaj qhov sib txawv tseem ceeb hauv kev tuav lub peev xwm, kev tiv thaiv sab hauv, sib xws, thiab kev nyab xeeb ntawm qib A, B-qib, thiab C-qib roj teeb. Thaum xaiv cov roj teeb, cov qib tsim nyog yuav tsum tau xaiv raws li cov xwm txheej tshwj xeeb ntawm daim ntawv thov thiab cov kev xav tau los xyuas kom meej qhov ua tau zoo thiab kev nyab xeeb ntawm cov khoom siv.
