KC,

▍ Dab tsi yogKC?

Txij thaum 25^thLub Yim Hli, 2008, Kaus Lim Kauslim Ministry of Knowledge Economy (MKE) tau tshaj tawm tias National Standard Committee yuav ua cov ntawv pov thawj tshiab hauv tebchaws - npeKCkos npe hloov daim ntawv pov thawj Korean thaum lub sij hawm lub Xya hli ntuj 2009 thiab Kaum Ob Hlis Ntuj 2010. Hluav taws xob cov khoom siv kev ruaj ntseg daim ntawv pov thawj scheme (KC Certification) yog ib tug yuav tsum tau thiab tus kheej-tswj kev ruaj ntseg daim ntawv pov thawj scheme raws li Hluav taws xob cov cuab yeej Safety Control Act, ib tug scheme uas certified kev ruaj ntseg 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

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.

Taiwan BSMI Group III tau hais nyob rau hauv ib daim ntawv xa mus rau lub chaw soj ntsuam BSMI dav dav rau lub Xya hli ntuj 21, 2022, tias lub chaw soj nstuam tswj qhov system yuav raug coj los ua kom muaj zog rau kev tswj hwm lub chaw soj nstuam thiab ua raws li cov kev sim thiab qhov xwm txheej. Cov kev siv cuam tshuam yog raws li hauv qab no.Los ntawm Lub Cuaj Hli 1, 2022, lub chaw soj nstuam ntawm cov khoom siv hluav taws xob kuaj xyuas nrog rau kev yeem tshuaj xyuas cov khoom thiab lwm yam yuav tsum tau: Hom ntawv xeem yuav tsum siv BSMI daim ntawv qhia tus naj npawb, lub chaw kuaj xyuas tus lej tuaj yeem xaiv khaws cia, tab sis ob daim ntawv tshaj tawm xov xwm yuav tsum muaj cov ntawv xov xwm tshwj xeeb.Lub chaw kuaj mob yuav tsum tau xa cov ntaub ntawv lees paub mus rau BSMI Kev Tshawb Fawb Kev Tshawb Fawb Daim Ntawv Thov Kev Siv Hauv 1 hnub tom qab tau txais cov qauv.Los ntawm cov txheej txheem kev tswj xyuas los ntawm pab pawg thib peb, BSMI muaj ntau thiab ntau cov kev cai nruj rau txhua qhov kev sim ntsuas qhov muaj peev xwm, lub voj voog ntsuas, thiab cov ntaub ntawv xeem. Kev txhim kho tom qab ntawm txoj kev tswj hwm yuav tsis muaj kev cuam tshuam rau cov qauv tuaj txog thiab kev tswj xyuas lub sijhawm, thiab MCM yuav khaws kev soj ntsuam thiab hloov kho raws sijhawm.
Crush yog qhov kev sim zoo heev los xyuas qhov kev nyab xeeb ntawm cov hlwb, simulating kev sib tsoo ntawm cov hlwb lossis cov khoom siv kawg hauv kev siv txhua hnub. Feem ntau muaj ob hom kev xeem crush: tiaj tus crush thiab ib nrab crush. Piv nrog rau lub tiaj tus crush, ib feem ntawm qhov indentation tshwm sim los ntawm ib tug kheej kheej los yog cylindrical indenter feem ntau yuav ua rau lub cell tsis zoo. Lub sharper lub indenter, qhov ntau concentrated qhov kev ntxhov siab nyob rau hauv lub core qauv ntawm lub lithium roj teeb, qhov loj dua lub rupture ntawm lub puab core, uas yuav ua rau deformation thiab txav ntawm lub hauv paus, thiab txawm ua rau loj txim xws li electrolyte to los yog. txawm hluav taws. Yog li yuav ua li cas crush coj mus rau lub deactivation ntawm tes? Ntawm no qhia koj txog kev hloov pauv hauv cov qauv ntawm cov tub ntxhais hauv kev xeem hauv zos extrusion.
