▍ 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.

Txheej txheem cej luam:
Electric scooter thiab skateboard muaj nyob rau hauv UL 2271 thiab UL 2272 thaum muaj ntawv pov thawj nyob rau hauv North America. Ntawm no yog cov lus qhia, ntawm qhov ntau yam uas lawv npog thiab cov kev cai, ntawm qhov sib txawv ntawm UL 2271 thiab UL 2272: UL 2271 yog hais txog cov roj teeb ntawm ntau yam khoom siv; thaum UL 2272 yog hais txog tus kheej cov khoom siv mobile. Nov yog cov npe ntawm cov teeb meem uas tau them los ntawm ob tus qauv:
L 2271 npog lub teeb tsheb roj teeb, suav nrog:
Fais tsheb kauj vab
Electric scooter thiab maus taus;
Lub rooj zaum fais fab
Lub laub golf
ATV;
Unmanned industrial carrier (xws li hluav taws xob forklift) ;
Siv lub tsheb thiab tshuab txiav;
Personal Mobile Devices (Electric Balance scooters)
UL 2272 yog muaj rau cov khoom siv ntawm tus kheej, xws li: hluav taws xob scooter thiab tsheb sib npaug.
Los ntawm tus txheej txheem, UL 2271 yog tus qauv roj teeb, thiab UL 2272 yog tus qauv ntaus ntawv. Thaum ua cov ntaub ntawv pov thawj ntawm UL 2272, lub roj teeb puas yuav tsum tau lees paub rau UL 2271 ua ntej?
Ua ntej, cia peb paub txog cov kev cai ntawm UL 2272 rau cov roj teeb (tsuas yog lithium-ion roj teeb / cell raug txiav txim siab hauv qab no):
Cell: lithium-ion hlwb yuav tsum ua raws li cov cai ntawm UL 2580 lossis UL 2271;
Roj teeb: Yog tias lub roj teeb ua tau raws li qhov yuav tsum tau ua ntawm UL 2271, nws tuaj yeem raug zam los ntawm cov kev ntsuam xyuas rau overcharge, luv-circuit, over-discharge thiab unbalanced charging.
Nws tuaj yeem pom tau tias yog tias lub roj teeb lithium siv rau hauv cov khoom siv uas siv tau rau UL 2272, nws tsis tas yuav tsum ua daim ntawv pov thawj UL 2271, tab sis lub xov tooj ntawm tes yuav tsum ua kom tau raws li cov cai ntawm UL 2580 lossis UL 2271.
Tsis tas li ntawd, cov kev cai ntawm lub tsheb roj teeb siv rau UL 2271 rau ntawm tes yog: lithium-ion hlwb yuav tsum tau ua raws li cov cai ntawm UL 2580.
Raws li cov ntsiab lus: ntev npaum li lub roj teeb ua tau raws li qhov yuav tsum tau ua ntawm UL 2580, qhov kev sim ntawm UL 2272 tuaj yeem tsis quav ntsej cov cai ntawm UL 2271, uas yog, yog tias lub roj teeb tsuas yog siv rau cov khoom siv uas haum rau UL 2272, nws yog Tsis tas yuav ua UL 2271 Certification.
