▍ 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 neshanu mainjiniya ane hunyanzvi mukuyedza sepaIEC 62133 standard. MCM inopa vatengi ruzivo rwakakwana, rwakakwana, rwakavharika-loop yerutsigiro rwehunyanzvi uye inotungamira-kumucheto ruzivo masevhisi.

Kuchengetedzwa kwesimba rekuchengetedza system chinhu chinowanzoitika. Sechimwe chezvinhu zvakakosha zvesimba rekuchengetedza sisitimu, kuchengetedzwa kwe lithium-ion bhatiri kunonyanya kukosha. Sezvo kupisa kwekupisa bvunzo kunogona kuongorora zvakananga njodzi yemoto inoitika musimba rekuchengetedza sisitimu, nyika zhinji dzakagadzira dzinoenderana nzira dzekuyedza mumiyero yadzo yekuongorora njodzi yekutiza kwekupisa. Semuyenzaniso, IEC 62619 yakapihwa neInternational Electrotechnical Commission (IEC) inotaura nzira yekuparadzira yekuongorora pesvedzero yekutiza kwekupisa kwesero; Chinese national standard GB/T 36276 inoda kupisa kunotiza kuongororwa kwesero uye kupisa kunotiza bvunzo yebhatiri module; Iyo US Underwriters Laboratories (UL) inoburitsa zviyero zviviri, UL 1973 uye UL 9540A, ese ari maviri anoongorora kupisa kwekupisa mhedzisiro. UL 9540A yakanyatsogadzirirwa kuongorora kubva kumatanho mana: sero, module, kabati, uye kuparadzira kupisa padanho rekuisa. Mhedzisiro yekudziya kwekupisa bvunzo haigone kungoongorora kuchengetedzwa kwese kwebhatiri, asi zvakare inotitendera kuti tikurumidze kunzwisisa kupisa kunotiza kwemasero, uye kupa maparamendi akafanana ekuchengetedza dhizaini yemasero ane makemikari akafanana. Iri rinotevera boka rekuyedza data rekutiza kwekupisa nderekuti iwe unzwisise maitiro ekupisa kwekupisa padanho rega rega uye zvinhu zviri muchitokisi. Nhanho yekutanga: Tembiricha inokwira zvishoma nezvishoma nekunze kwekudziya sosi. Panguva ino, chiyero chekugadzira kupisa kwesero ndeye 0 ℃ / min (0 ~ T1), sero pachayo haina kupisa, uye hapana chemikemikari inoshandiswa mukati. Nekuwedzera kwekushisa, SEI firimu rinotanga kunyungudika kana rasvika panosvika 90 ℃ (T1). Panguva ino, sero richava zvishoma kuzvipisa kusunungurwa, uye inogona kuonekwa kubva Figure 1 (B) kuti tembiricha kukwira mwero fluctuates.Stage 3 ndiyo electrolyte decomposition danho (T1~ T2). Kana tembiricha yasvika 110 ℃, iyo electrolyte uye iyo yakaipa electrode, pamwe neiyo electrolyte pachayo ichaitika nhevedzano yekuora maitiro, ichiburitsa huwandu hukuru hwegasi. Iyo inoramba ichigadzira gasi inoita kuti kudzvanywa kwemukati mesero kuwedzere zvakanyanya, ichisvika pakudzvinyirira kukosha, uye gasi rinopedza simba rinovhura (T2). Panguva ino, gasi rakawanda, electrolytes uye zvimwe zvinhu zvinoburitswa, zvichibvisa chikamu chekupisa, uye tembiricha inowedzera inova yakaipa.
