▍ Chii chinonzi CB Certification?

IECEE CB ndiyo yekutanga yechokwadi yepasirese sisitimu yekuzivikanwa pamwe chete kwemagetsi emagetsi ekuchengetedza bvunzo mishumo.NCB (National Certification Body) inosvika pachibvumirano chenyika dzakawanda, icho chinoita kuti vagadziri vawane chitupa chenyika kubva kune dzimwe nyika nhengo pasi pechirongwa cheCB nechikonzero chekuendesa chimwe chezvitupa zveNCB.

Chitupa cheCB igwaro repamutemo reCB scheme rakapihwa neNCB ine mvumo, inova yekuzivisa imwe NCB kuti masampula echigadzirwa akaedzwa anowirirana nezvinodiwa zvakajairwa.

Serudzi rwemushumo wakamisikidzwa, mushumo weCB unonyora zvakakodzera zvinodiwa kubva kuIEC yakajairika chinhu nechinhu.Chirevo cheCB hachingopi mhedzisiro yezvese zvinodiwa kuyedzwa, kuyerwa, kuonesa, kuongorora uye kuongorora nekujeka uye kusanzwisisika, asi zvakare kusanganisira mafoto, dhizaini redunhu, mapikicha uye tsananguro yechigadzirwa.Zvinoenderana nemutemo weCB scheme, chirevo cheCB hachizoshanda kudzamara chaunza chitupa cheCB pamwechete.

▍ Nei tichida CB Certification?

1. Directlyrecognized or approvedbynhengonyika

Iine CB chitupa uye CB test report, zvigadzirwa zvako zvinogona kutumirwa kune dzimwe nyika zvakananga.

1. Shandura kune dzimwe nyika zvitupa

Chitupa cheCB chinogona kushandurwa zvakananga kuchitupa chenyika dzenhengo dzayo, nekupa chitupa cheCB, mushumo webvunzo uye mutsauko webvunzo mushumo (kana uchishanda) pasina kudzokorora bvunzo, izvo zvinogona kupfupisa nguva yekutungamira yechitupa.

1. Ita shuwa Kuchengetedzeka kweChigadzirwa

Iyo CB certification bvunzo inotarisa kushandiswa zvine musoro kwechigadzirwa uye chengetedzo inofanoona kana ikashandiswa zvisizvo.Chigadzirwa chakasimbiswa chinoratidza kugutsikana kwezvinodiwa zvekuchengetedza.

▍ Neiko MCM?

● Zvikwaniriso:MCM ndiyo yekutanga kupihwa mvumo CBTL yeIEC 62133 yakajairwa kufanirwa neTUV RH mudunhu reChina.

● Certification uye kuyedza kugona:MCM iri pakati pekutanga kuyedza uye certification yechitatu bato yeIEC62133 yakajairwa, uye yapedza zvinopfuura zviuru zvinomwe zvebhatiri IEC62133 kuyedza uye CB mishumo yevatengi vepasirese.

● Rutsigiro rwehunyanzvi:MCM ine anopfuura gumi nemashanu mainjiniya ane hunyanzvi mukuyedza sepaIEC 62133 standard.MCM inopa vatengi ruzivo rwakakwana, rwakakwana, rwakavharwa-loop yerutsigiro rwehunyanzvi uye inotungamira-kumucheto ruzivo masevhisi.

Zvichitevera mwedzi wapera kuwedzera kwehuremu hwekuita kwepouch cell, mwedzi uno UL 1642 yakaronga kuwedzera chiyero chekuedza kune yakasimba state lithium masero.Parizvino, mabhatiri ehurumende akasimba akawanda anobva pamabhatiri e-lithium-sarufa.Lithium-sarufa bhatiri ine yakakwirira chaiyo kugona (1672mAh/g) uye simba density (2600Wh/kg), inova ka5 kashanu pane yechinyakare lithium-ion bhatiri.Naizvozvo, yakasimba state bhatiri ndeimwe yeinopisa-nzvimbo yelithium bhatiri.Zvisinei, kuchinja kukuru kwehuwandu hwesarufa cathode panguva ye delithium / lithium, dambudziko re dendrite re lithium anode uye kushayikwa kwekugadzirisa kwe electrolyte yakasimba kwakadzivisa kutengeswa kwe sulfur cathode.Saka kwemakore, vatsvakurudzi vanga vachishanda pakuvandudza electrolyte uye interface yebhatiri yehurumende yakasimba.UL 1642 inowedzera kurudziro iyi nechinangwa chekugadzirisa zvinobudirira matambudziko anokonzerwa nebhatiri yakasimba (uye sero) maitiro uye njodzi dzinogona kuitika kana dzichishandiswa.Mushure mezvose, masero ane sulphide electrolytes anogona kuburitsa gasi rine muchetura senge hydrogen sulphide pasi pemamwe mamiriro akanyanya.Naizvozvo, mukuwedzera kune mamwe maedzo enguva dzose, isu tinoda zvakare kuyera ine muchetura gasi rekuisa mushure mebvunzo.Chaiyo bvunzo zvinhu zvinosanganisira: kuyerwa kwesimba, kupfupika, kubhadharisa, kumanikidza kuburitsa, kuvhunduka, kupwanya, kukanganisa, kuzununguka, kudziyisa, tembiricha kutenderera, kuderera, kupiswa kwejeti uye kuyerwa kwehupfu. Iyo yakajairwa GB/T 35590, iyo inovhara inotakurika magetsi sosi, haina kuisirwa mu3C certification.Chikonzero chikuru chinogona kunge chiri chekuti GB/T 35590 inobhadhara zvakanyanya pakuita kweinotakurika simba sosi pane kuchengetedza, uye zvinodiwa zvekuchengetedza zvinonyanya kutaurwa kuGB 4943.1.Nepo 3C certification iri pamusoro pekuve nechokwadi chekuchengetedzwa kwechigadzirwa, saka GB 4943.1 inosarudzwa seyakajairwa chitupa chemagetsi anotakurika sosi.
