▍ 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 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.

Xov xwm keeb kwm yav dhau:
1. Nyob rau lub Plaub Hlis 2021, Cov Lus Qhia Txog Kev Txhim Kho Kev Txhim Kho Lub Zog Tshiab (Draft for Comment) tau koom ua ke los ntawm National Development thiab Reform Commission thiab National Energy Administration tau taw qhia tias kev sib txawv ntawm cov cuab yeej siv hluav taws xob yuav tsum tau khaws cia thiab nrawm. txoj kev loj hlob ntawm cov kev sim loj thiab ua qauv qhia ntawm cov thev naus laus zis xws li flywheel zog cia thiab sodium roj teeb
2. Thaum tham txog qhov teeb meem ntawm kev nce nqi ntawm cov khoom siv raw khoom ntawm lub tuam txhab 2020 lub rooj sib tham txhua xyoo ntawm cov tswv lag luam, tus thawj coj ntawm CATL, Zeng Yuqun, tau tshaj tawm lwm cov lus tseem ceeb uas lub tshuab hluav taws xob sodium yog cov paub tab thiab cov khoom muaj feem xyuam yuav raug tso tawm hauv Lub Xya hli ntuj.Lo lus lub ntsiab lus tsom xam: Sodium-ion roj teeb, uas feem ntau yog nyob ntawm kev txav ntawm sodium ions ntawm qhov zoo thiab tsis zoo electrodes, zoo ib yam li lithium-ion roj teeb.Sodium roj teebQhov zoo ntawm cov roj teeb sodium:
Cov khoom siv raw khoom ntawm sodium ntsev yog ntau thiab tus nqi qis; Lub peev xwm ib nrab ntawm cov roj teeb sodium ion yog 0.3 ~ 0.4V siab dua li ntawm lithium ion, uas yog, electrolyte hnyav thiab electrolyte ntsev nrog qis decomposition poten tial tuaj yeem siv, thiab kev xaiv ntawm electrolyte yog dav dua; Sodium ion roj teeb muaj qhov ruaj khov electrochemical kev ua tau zoo thiab muaj kev nyab xeeb dua rau kev siv; Txij li cov roj teeb sodium ion tsis muaj cov yam ntxwv tshaj tawm, sodium ion roj teeb tau tso cai tawm mus rau xoom volts.
