Qhov teeb meem ntawm UL 1642 tshiab hloov tshiab - Kev hloov pauv hnyav rau lub hnabcell,
cell,

▍ KC yog dab tsi?

Txij thaum 25^thLub Yim Hli, 2008, Kaus Lim Kauslim Ministry of Knowledge Economy (MKE) tshaj tawm tias National Standard Committee yuav ua ib lub teb chaws tshiab daim ntawv pov thawj - lub npe KC cim hloov Korean Certification thaum lub sij hawm lub Xya hli ntuj 2009 thiab Kaum Ob Hlis 2010. Cov khoom siv hluav taws xob muaj ntawv pov thawj kev nyab xeeb scheme (KC Certification) yog qhov yuav tsum tau ua thiab kev tswj hwm tus kheej kev nyab xeeb kev pom zoo raws li Kev Tswj Xyuas Hluav Taws Xob Hluav Taws Xob Kev Nyab Xeeb Txoj Cai, ib lub tswv yim uas tau lees paub kev nyab xeeb ntawm kev tsim khoom thiab muag.

Qhov txawv ntawm qhov yuav tsum tau ntawv pov thawj thiab kev tswj tus kheej( yeem)kev ruaj ntseg:

Rau kev tswj xyuas kev nyab xeeb ntawm cov khoom siv hluav taws xob, KC ntawv pov thawj tau muab faib ua kev tswj hwm tus kheej thiab kev tswj hwm tus kheej (daim ntawv pov thawj) kev nyab xeeb raws li kev faib tawm ntawm kev phom sij ntawm cov khoom.Cov ntsiab lus ntawm Kev Tswj Xyuas Cov Ntawv Pov Thawj yog siv rau cov khoom siv hluav taws xob uas nws cov qauv thiab cov txheej txheem ntawm daim ntawv thov yuav ua rau Qhov tshwm sim txaus ntshai lossis teeb meem xws li hluav taws kub, hluav taws xob poob siab. Thaum cov ntsiab lus ntawm kev tswj hwm tus kheej (daim ntawv pov thawj) kev nyab xeeb yog siv rau cov khoom siv hluav taws xob uas nws cov qauv thiab cov txheej txheem ntawm daim ntawv thov tsis tuaj yeem ua rau muaj kev phom sij loj lossis cuam tshuam xws li hluav taws xob, hluav taws xob poob siab. Thiab qhov txaus ntshai thiab teeb meem tuaj yeem tiv thaiv los ntawm kev sim cov khoom siv hluav taws xob.

▍ Leej twg tuaj yeem thov rau KC ntawv pov thawj:

Txhua tus neeg raug cai lossis cov neeg nyob hauv tsev thiab txawv teb chaws uas koom nrog hauv kev tsim khoom, sib dhos, ua cov khoom siv hluav taws xob.

▍ Cov txheej txheem thiab txheej txheem ntawm kev pov thawj kev nyab xeeb:

Thov rau KC ntawv pov thawj nrog cov khoom lag luam tus qauv uas tuaj yeem muab faib ua cov qauv yooj yim thiab cov qauv series.

Txhawm rau kom paub meej hom qauv thiab tsim cov khoom siv hluav taws xob, ib lub npe khoom tshwj xeeb yuav raug muab raws li nws txoj haujlwm sib txawv.

▍ KC ntawv pov thawj rau Lithium roj teeb

1. KC daim ntawv pov thawj tus qauv rau lithium roj teeb:KC62133:2019
2. Khoom Scope ntawm KC ntawv pov thawj rau lithium roj teeb

A. Secondary lithium roj teeb rau siv nyob rau hauv daim ntawv thov portable los yog tshem tau cov khoom

B. Cell tsis raug KC daim ntawv pov thawj txawm tias muag lossis sib sau ua ke hauv cov roj teeb.

C. Rau cov roj teeb uas siv rau hauv cov khoom siv hluav taws xob los yog UPS (tsis cuam tshuam lub zog hluav taws xob), thiab lawv lub zog uas ntau dua 500Wh yog dhau qhov kev txwv.

D. Lub roj teeb uas nws lub zog ntim qis dua 400Wh / L los rau hauv cov ntawv pov thawj txij li 1^st, Lub Plaub Hlis 2016.

▍ Vim li cas MCM?

● MCM khaws kev koom tes nrog Kaus Lim Kauslim cov chaw sim, xws li KTR (Korea Testing & Research Institute) thiab muaj peev xwm muab cov kev daws teeb meem zoo tshaj plaws nrog kev ua haujlwm siab thiab muaj txiaj ntsig ntxiv rau cov neeg siv khoom los ntawm lub sijhawm ua cov txheej txheem kuaj, ntawv pov thawj nqi.

● KC ntawv pov thawj rau rechargeable lithium roj teeb tuaj yeem tau txais los ntawm kev xa daim ntawv pov thawj CB thiab hloov mus rau hauv daim ntawv pov thawj KC. Raws li CBTL raws li TÜV Rheinland, MCM tuaj yeem muab cov ntawv ceeb toom thiab daim ntawv pov thawj uas tuaj yeem thov rau kev hloov pauv ntawm KC daim ntawv pov thawj ncaj qha. Thiab lub sij hawm txhuas tuaj yeem ua kom luv yog tias thov CB thiab KC tib lub sijhawm. Dab tsi ntxiv, tus nqi cuam tshuam yuav zoo dua.

Ib qho tshiab ntawm UL 1642 tau tso tawm. Ib qho ntxiv rau qhov kev ntsuam xyuas hnyav yog ntxiv rau lub hnab ntim. Cov kev cai tshwj xeeb yog: Rau lub hnab ntawm tes nrog lub peev xwm ntau dua 300 mAh, yog tias dhau qhov kev ntsuas hnyav tsis dhau, lawv tuaj yeem raug rau Tshooj 14A round pas nrig extrusion test.Pouch cell tsis muaj rooj plaub nyuaj, uas feem ntau ua rau cell rupture, kais tawg, khib nyiab ya tawm thiab lwm yam kev puas tsuaj loj tshwm sim los ntawm tsis ua hauj lwm nyob rau hauv hnyav kev ntsuam xyuas, thiab ua rau nws tsis yooj yim sua kom paub lub internal luv luv Circuit Court tshwm sim los ntawm tus tsim tsis xws luag los yog txheej txheem defect. Nrog rau kev sib tw qws sib tsoo, qhov ua tau tsis zoo hauv lub xov tooj tuaj yeem kuaj pom yam tsis muaj kev puas tsuaj rau cov qauv ntawm tes. Kev hloov kho tau ua nrog qhov teeb meem no hauv kev txiav txim siab.Cov qauv no raug them tag nrho raws li kev pom zoo los ntawm cov chaw tsim khoomPhoj tus qauv rau ntawm qhov chaw tiaj tus. Muab ib puag ncig steel pas nrig nrog txoj kab uas hla ntawm 25 ± 1mm ​​rau saum cov qauv. Lub ntug ntawm tus pas nrig yuav tsum tau ua raws li sab saum toj ntawm lub xovtooj ntawm tes, nrog rau txoj kab ntsug ntsug perpendicular mus rau lub tab (Daim duab 1). Qhov ntev ntawm tus pas nrig yuav tsum yog tsawg kawg yog 5 hli dav dua txhua ntug ntawm cov qauv kuaj. Rau cov hlwb uas muaj qhov zoo thiab qhov tsis zoo ntawm sab nraud, txhua sab ntawm tab yuav tsum tau sim. Txhua sab ntawm tab yuav tsum raug kuaj ntawm cov qauv sib txawv.Kev ntsuas qhov tuab (kev ua siab ntev ± 0.1mm) rau cov hlwb yuav tsum tau ua ua ntej kev sim ua raws li Daim Ntawv Ntxiv A ntawm IEC 61960-3 (Cov hlwb thib ob thiab cov roj teeb uas muaj alkaline lossis lwm yam tsis yog- Acidic electrolytes - Portable Secondary lithium Cell thiab roj teeb - Ntu 3: Prismatic thiab cylindrical lithium Secondary Cell thiab roj teeb)
