▍ 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 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 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 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.

Raws li cov ntaub ntawv tsis ntev los no tau tshaj tawm los ntawm Tuam Tshoj Ministry of Emergency Management, 640 qhov xwm txheej hluav taws kub ntawm lub zog tshiab tau tshaj tawm nyob rau thawj peb lub hlis twg xyoo 2022, nce 32% nyob rau tib lub sijhawm xyoo tas los, nrog qhov nruab nrab ntawm 7 hluav taws kub ib hnub. Tus sau tau ua qhov kev txheeb xyuas los ntawm lub xeev ntawm qee qhov hluav taws kub EV, thiab pom tias tus nqi hluav taws xob hauv lub xeev tsis siv, lub xeev tsav tsheb thiab lub xeev them nqi ntawm EV tsis txawv ntawm ib leeg, raws li qhia hauv daim duab hauv qab no. Tus sau yuav ua ib qho kev soj ntsuam yooj yim ntawm qhov ua rau hluav taws kub hauv peb lub xeev no thiab muab cov tswv yim tsim kev nyab xeeb.Txawm hais tias qhov xwm txheej twg ua rau lub roj teeb hluav taws kub lossis tawg, lub hauv paus ua rau yog luv luv hauv lossis sab nraud ntawm tes, uas ua rau thermal khiav ntawm lub cell. Tom qab lub thermal runaway ntawm ib lub xov tooj ntawm tes, nws thaum kawg yuav ua rau tag nrho cov pob ntes hluav taws yog tias thermal nthuav tawm tsis tuaj yeem zam vim yog cov qauv tsim ntawm module lossis pob. Ua rau sab hauv lossis sab nraud luv luv ntawm lub xov tooj ntawm tes yog (tab sis tsis txwv rau): overheating, overcharge, tshaj tawm, mechanical quab yuam (tshem, poob siab), Circuit Court aging, hlau hais mus rau hauv lub cell nyob rau hauv cov txheej txheem ntau lawm, thiab lwm yam.Thaum lub cell tau txais cov cua sov sab nraud los yog nws tus kheej-tsim cua sov thiab tsis tuaj yeem dissipate nyob rau hauv lub sij hawm, thiab qhov kub ntawm lub xov tooj ntawm tes tshaj qhov kub ntawm cov khoom siv sab hauv (separator), tus separator yuav cog lus, uas ua rau luv luv Circuit Court ntawm qhov zoo thiab tsis zoo electrodes.Ntau zaus overcharging. yuav ua rau lithium nag lossis daus nyob rau hauv lub cell, thiab lithium hlau yuav loj hlob zoo li dendrites thiab thaum kawg puncture lub separator, uas ua rau lub sab hauv luv luv Circuit Court ntawm qhov zoo thiab tsis zoo electrodes.
