▍ KC yog dab tsi?
Txij thaum 25thLub 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 lees paub kev nyab xeeb:
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
- KC daim ntawv pov thawj tus qauv rau lithium roj teeb:KC62133:2019
- 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 1st, 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 sijhawm ua haujlwm tuaj yeem ua kom luv yog tias thov CB thiab KC tib lub sijhawm. Dab tsi ntxiv, tus nqi cuam tshuam yuav zoo dua.
Kev nyab xeeb ntawm lub zog cia system yog ib qho kev txhawj xeeb. Raws li ib qho ntawm cov khoom tseem ceeb ntawm lub zog cia, kev nyab xeeb ntawm lithium-ion roj teeb yog qhov tseem ceeb tshwj xeeb. Raws li kev ntsuas thermal runaway tuaj yeem ntsuas ncaj qha qhov kev pheej hmoo ntawm hluav taws kub tshwm sim hauv lub zog cia, ntau lub teb chaws tau tsim cov kev sim sib xws hauv lawv cov qauv los ntsuas qhov kev pheej hmoo ntawm thermal runaway. Piv txwv li, IEC 62619 tawm los ntawm International Electrotechnical Commission (IEC) qhia txog txoj kev nthuav tawm los ntsuas qhov cuam tshuam ntawm thermal runaway ntawm tes; Suav teb chaws tus qauv GB / T 36276 yuav tsum tau thermal runaway ntsuam xyuas ntawm tes thiab thermal runaway xeem ntawm lub roj teeb module; Lub US Underwriters Laboratories (UL) luam tawm ob tus qauv, UL 1973 thiab UL 9540A, ob qho tib si ntsuas cov teebmeem thermal runaway. UL 9540A yog tsim tshwj xeeb los ntsuas los ntawm plaub theem: cell, module, txee, thiab cua sov propagation ntawm theem installation. Cov txiaj ntsig ntawm thermal runaway test tsis tuaj yeem ntsuas qhov kev nyab xeeb tag nrho ntawm lub roj teeb, tab sis tseem tso cai rau peb kom nkag siab sai sai ntawm thermal runaway ntawm cov hlwb, thiab muab cov kev sib piv rau kev nyab xeeb tsim ntawm cov hlwb nrog cov tshuaj zoo sib xws. Cov pab pawg hauv qab no ntawm kev sim cov ntaub ntawv rau thermal runaway yog rau koj kom nkag siab txog cov yam ntxwv ntawm thermal runaway ntawm txhua theem thiab cov ntaub ntawv hauv cell.
Raws li qhov sib txawv ntawm thermal runaway kub, cov txheej txheem tau muab faib ua tsib theem (Daim duab 1 qhia qhov ntsuas kub hloov pauv ntawm ib pawg ntawm kev ntsuas thermal khiav):
