▍ 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.

Tam sim no, feem ntau cov roj teeb hauv lub xeev yog ua raws li cov roj teeb lithium-sulfur. Lithium-sulfur roj teeb muaj peev xwm tshwj xeeb (1672mAh / g) thiab lub zog ceev (2600Wh / kg), uas yog 5 npaug ntawm cov roj teeb lithium-ion ib txwm muaj. Yog li ntawd, cov roj teeb lub xeev yog ib qho ntawm cov kub-qhov chaw ntawm lithium roj teeb. Txawm li cas los xij, qhov kev hloov pauv tseem ceeb hauv cov ntim ntawm sulfur cathode thaum lub sij hawm tus txheej txheem ntawm delithium / lithium, qhov teeb meem dendrite ntawm lithium anode thiab tsis muaj conductivity ntawm cov khoom electrolyte tau cuam tshuam kev lag luam ntawm sulfur cathode. Yog li ntawd tau ntau xyoo, cov kws tshawb fawb tau ua haujlwm los txhim kho cov electrolyte thiab cuam tshuam ntawm cov roj teeb hauv lub xeev.
UL 1642 ntxiv cov lus pom zoo no nrog lub hom phiaj ntawm kev daws cov teeb meem zoo los ntawm cov roj teeb (thiab cov xov tooj ntawm tes) cov yam ntxwv thiab muaj peev xwm txaus ntshai thaum siv. Tom qab tag nrho, cov hlwb uas muaj sulfide electrolytes tuaj yeem tso cov pa phem xws li hydrogen sulphide nyob rau hauv qee qhov xwm txheej hnyav. Yog li ntawd, ntxiv rau qee qhov kev ntsuam xyuas niaj hnub, peb kuj yuav tsum ntsuas cov pa roj carbon monoxide tom qab kev sim. Cov khoom kuaj tshwj xeeb muaj xws li: ntsuas qhov muaj peev xwm, luv luv Circuit Court, tsis raug nqi, yuam kev tawm, poob siab, tsoo, cuam tshuam, kev co, cua sov, lub voj voog kub, tsis tshua muaj siab, dav hlau combustion, thiab ntsuas cov tshuaj lom emissions.The standard GB/T 35590, uas npog portable fais fab mov, tsis suav nrog 3C ntawv pov thawj. Qhov laj thawj tseem ceeb yog vim li cas GB / T 35590 tau them nyiaj ntau dua rau kev ua haujlwm ntawm cov khoom siv hluav taws xob portable es tsis yog kev nyab xeeb, thiab cov kev xav tau kev nyab xeeb feem ntau raug xa mus rau GB 4943.1. Thaum 3C ntawv pov thawj yog ntau ntxiv txog kev ua kom cov khoom muaj kev ruaj ntseg, yog li GB 4943.1 raug xaiv raws li tus qauv ntawv pov thawj rau lub zog portable.
