▍ Daim ntawv pov thawj CB yog dab tsi?

IECEE CB yog thawj txoj hauv kev thoob ntiaj teb rau kev sib koom ua ke ntawm cov khoom siv hluav taws xob kev nyab xeeb kev xeem ntawv ceeb toom. NCB (National Certification Body) ncav cuag ntau qhov kev pom zoo, uas ua rau cov tuam txhab tau txais daim ntawv pov thawj hauv tebchaws los ntawm lwm lub teb chaws cov tswv cuab raws li CB cov tswv yim raws li kev hloov pauv ib qho ntawm NCB daim ntawv pov thawj.

CB daim ntawv pov thawj yog ib daim ntawv pov thawj CB raws li daim ntawv tso cai NCB, uas yog qhia rau lwm tus NCB tias cov khoom kuaj kuaj ua raws li cov qauv yuav tsum tau ua.

Raws li hom ntawv tshaj tawm, CB daim ntawv tshaj tawm teev cov kev xav tau los ntawm IEC tus qauv khoom los ntawm cov khoom. CB daim ntawv tshaj tawm tsis yog tsuas yog muab cov txiaj ntsig ntawm txhua qhov kev ntsuas uas xav tau, ntsuas, tshawb xyuas, tshuaj xyuas thiab kev ntsuas nrog qhov tseeb thiab tsis meej, tab sis kuj suav nrog cov duab, daim duab kos duab, duab thiab cov lus piav qhia ntawm cov khoom. Raws li txoj cai ntawm CB scheme, CB daim ntawv tshaj tawm yuav tsis siv mus txog thaum nws nthuav tawm nrog CB daim ntawv pov thawj ua ke.

▍ Vim li cas peb thiaj xav tau CB Certification?

1. Ncaj nraimlylees paubzej or pom zooedlos ntawmtus tswv cuablub teb chaws

Nrog CB daim ntawv pov thawj thiab CB xeem daim ntawv tshaj tawm, koj cov khoom tuaj yeem raug xa tawm mus rau qee lub tebchaws ncaj qha.

1. Hloov mus rau lwm lub tebchaws daim ntawv pov thawj

Daim ntawv pov thawj CB tuaj yeem hloov pauv ncaj qha mus rau daim ntawv pov thawj ntawm nws cov tswvcuab hauv tebchaws, los ntawm kev muab CB daim ntawv pov thawj, daim ntawv pov thawj kev xeem thiab cov ntawv xeem sib txawv (thaum muaj feem xyuam) yam tsis tau rov ua dua qhov kev xeem, uas tuaj yeem txo lub sijhawm ua haujlwm ntawm kev lees paub.

1. Xyuas kom muaj kev nyab xeeb ntawm cov khoom

CB daim ntawv pov thawj kuaj xyuas cov khoom siv tsim nyog thiab pom tau tias muaj kev nyab xeeb thaum siv tsis raug. Cov khoom muaj ntawv pov thawj ua pov thawj qhov txaus siab ntawm qhov yuav tsum tau muaj kev nyab xeeb.

▍ Vim li cas MCM?

● Kev Tsim Nyog:MCM yog thawj daim ntawv tso cai CBTL ntawm IEC 62133 tus qauv tsim nyog los ntawm TUV RH hauv Suav teb av loj.

● Daim ntawv pov thawj thiab kev xeem muaj peev xwm:MCM yog thawj thaj chaw ntawm kev sim thiab ntawv pov thawj thib peb rau IEC62133 tus qauv, thiab tau ua tiav ntau tshaj 7000 roj teeb IEC62133 kev sim thiab CB cov ntaub ntawv rau cov neeg siv khoom thoob ntiaj teb.

● Kev pab txhawb nqa:MCM muaj ntau dua 15 tus kws tshaj lij kws tshaj lij tshwj xeeb hauv kev sim raws li IEC 62133 tus qauv. MCM muab cov neeg siv khoom nrog cov lus qhia dav dav, raug, kaw-voj hom kev txhawb nqa thiab cov kev pabcuam cov ntaub ntawv ua ntej.

Tom qab lub hli tas los qhov ntxiv ntawm qhov hnyav hnyav rau lub hnab ntawm tes, lub hli no UL 1642 tau thov kom ntxiv ib qho kev sim rau lub xeev lithium cell.Tam sim no, cov roj teeb hauv lub xeev feem ntau yog 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 qhov 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 khoom siv 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.
