▍Siyini Isitifiketi Se-CB?

I-IECEE CB iwuhlelo lokuqala lwangempela lwamazwe ngamazwe lokuqashelwa ngokufanayo kwemibiko yokuhlolwa kokuphepha kwezinto zikagesi. I-NCB (National Certification Body) ifinyelela isivumelwano sezizwe eziningi, esivumela abakhiqizi ukuthi bathole isitifiketi sikazwelonke kwamanye amazwe angamalungu ngaphansi kohlelo lwe-CB ngesisekelo sokudlulisa esinye sezitifiketi ze-NCB.

Isitifiketi se-CB siwumbhalo osemthethweni wohlelo lwe-CB okhishwe i-NCB egunyaziwe, okokwazisa enye i-NCB ukuthi amasampula omkhiqizo ohloliwe ahambisana nezidingo ezijwayelekile.

Njengohlobo lombiko omisiwe, umbiko we-CB ubala izidingo ezifanele ezivela entweni ejwayelekile ye-IEC ngento ngayinye. Umbiko we-CB awuhlinzeki nje kuphela ngemiphumela yakho konke ukuhlolwa okudingekile, ukukalwa, ukuqinisekiswa, ukuhlolwa nokuhlola ngokucacile nokungacacisi, kodwa futhi kufaka phakathi izithombe, umdwebo wesifunda, izithombe nencazelo yomkhiqizo. Ngokomthetho wohlelo lwe-CB, umbiko we-CB ngeke usebenze kuze kube yilapho wethula isitifiketi se-CB ndawonye.

▍Kungani sidinga Isitifiketi se-CB?

1. Ngqolyqaphelazed or vumaedngeilunguamazwe

Ngesitifiketi se-CB kanye nombiko wokuhlola we-CB, imikhiqizo yakho ingathunyelwa kwamanye amazwe ngokuqondile.

1. Guqulela kwamanye amazwe izitifiketi

Isitifiketi se-CB singaguqulelwa ngokuqondile kusitifiketi samazwe angamalungu ayo, ngokunikeza isitifiketi se-CB, umbiko wokuhlola kanye nombiko wokuhlola umehluko (uma kusebenza) ngaphandle kokuphinda ukuhlolwa, okunganciphisa isikhathi sokuhola sokuthola isitifiketi.

1. Qinisekisa Ukuphepha Komkhiqizo

Ukuhlolwa kwesitifiketi se-CB kubheka ukusetshenziswa okuphusile komkhiqizo kanye nokuphepha okubonakalayo uma usetshenziswa kabi. Umkhiqizo oqinisekisiwe ufakazela ukugculisa kwezidingo zokuphepha.

▍Kungani i-MCM?

● Ukufaneleka:I-MCM iyi-CBTL yokuqala egunyaziwe ye-IEC 62133 ejwayelekile yi-TUV RH ezweni laseChina.

● Isitifiketi namandla okuhlola:I-MCM iphakathi kwesiqephu sokuqala sokuhlola nesitifiketi senkampani yangaphandle ye-IEC62133 ejwayelekile, futhi isiqede ukuhlola amabhethri e-IEC62133 angaphezu kuka-7000 kanye nemibiko ye-CB kumakhasimende omhlaba.

● Usekelo lobuchwepheshe:I-MCM inonjiniyela bezobuchwepheshe abangaphezu kwe-15 abakhethekile ekuhlolweni njengokujwayelekile kwe-IEC 62133. I-MCM ihlinzeka amakhasimende ngohlobo oluphelele, olunembile, oluvaliwe losekelo lobuchwepheshe kanye nezinsizakalo zolwazi ezihola phambili.

Ngemva kokwengezwa kwenyanga edlule komthelela osindayo wesikhwama sesikhwama, kule nyanga i-UL 1642 ihlongoze ukungeza imfuneko yokuhlola yamaseli e-lithium wesimo esiqinile.Okwamanje, amabhethri amaningi esimo esiqinile asekelwe kumabhethri e-lithium-sulphur. Ibhethri le-lithium-sulphur linomthamo othize ophezulu (1672mAh/g) kanye nokuminyana kwamandla (2600Wh/kg), okuyizikhathi ezingu-5 kunebhethri le-lithium-ion lendabuko. Ngakho-ke, ibhethri yesimo esiqinile ingenye yezindawo ezishisayo zebhethri ye-lithium. Kodwa-ke, izinguquko eziphawulekayo kumthamo we-sulphur cathode phakathi nenqubo ye-delithium/lithium, inkinga ye-dendrite ye-lithium anode kanye nokuntuleka kokuhamba kwe-electrolyte eqinile kuye kwavimbela ukuthengiswa kwe-sulfur cathode. Ngakho-ke iminyaka eminingi, abacwaningi bebesebenzela ukuthuthukisa i-electrolyte kanye nokuxhumana kwebhethri yesimo esiqinile.UL 1642 yengeza lesi sincomo ngenhloso yokuxazulula ngempumelelo izinkinga ezibangelwa izici zebhethri eliqinile (kanye neseli) kanye nezingozi ezingaba khona lapho zisetshenziswa. Phela, amaseli aqukethe i-sulphide electrolyte angase akhulule igesi enobuthi njenge-hydrogen sulphide ngaphansi kwezimo ezithile ezimbi kakhulu. Ngakho-ke, ngaphezu kwezinye izivivinyo ezijwayelekile, sidinga futhi ukukala ukugcwala kwegesi enobuthi ngemva kokuhlolwa. Izinto zokuhlola eziqondile zihlanganisa: ukukalwa kwamandla, isifunda esifushane, ukushaja okungavamile, ukukhipha okuphoqelekile, ukushaqeka, ukuchoboza, umthelela, ukudlidliza, ukufudumeza, umjikelezo wezinga lokushisa, umfutho ophansi, indiza evuthayo, nesilinganiso sokukhishwa okunobuthi. I-GB/T 35590 evamile, okuyinto imboza umthombo wamandla ophathekayo, ayifakiwe kusitifiketi se-3C. Isizathu esiyinhloko kungaba ukuthi i-GB/T 35590 inaka kakhulu ukusebenza komthombo wamandla aphathwayo kunokuphepha, futhi izidingo zokuphepha zibhekiselwa kakhulu ku-GB 4943.1. Nakuba isitifiketi se-3C simayelana nokuqinisekisa ukuphepha komkhiqizo, ngakho-ke i-GB 4943.1 ikhethwa njengezinga lokuqinisekisa lomthombo wamandla ophathwayo.
