I-UL 1642wengeze isidingo sokuhlola samaseli esimo esiqinile,
I-UL 1642,

▍Iyini i-KC?

Kusukela 25^thAug., 2008，Korea Ministry of Knowledge Economy (MKE) yamemezela ukuthi I-National Standard Committee izophatha uphawu olusha lwesitifiketi oluhlanganisiwe lukazwelonke - oluqanjwe uphawu lwe-KC oluthatha indawo yesitifiketi sase-Korea phakathi nesikhathi esiphakathi kuka-Jul. 2009 no-Dec. 2010. Isitifiketi sokuphepha se-Electrical Appliances isikimu (Isitifiketi se-KC) siwuhlelo lokuqinisekisa ukuphepha oluyisibopho futhi oluzilawulayo ngokwe-Electrical I-Appliances Safety Control Act, uhlelo oluqinisekisa ukuphepha kokukhiqizwa nokudayiswa.

Umehluko phakathi kwesitifiketi esiyisibopho nokuzilawula(ngokuzithandela)isiqinisekiso sokuphepha:

Ukuze kuphathwe ngokuphephile izinto zikagesi, isitifiketi se-KC sihlukaniswe izitifiketi zokuphepha eziphoqelekile nezizilawulayo (ngokuzithandela) njengokuhlukaniswa kwengozi yomkhiqizo. imiphumela eyingozi engathi sína noma isithiyo esinjengomlilo, ukushaqeka kukagesi. Ngenkathi izifundo zesitifiketi sokuphepha esizilawulayo (sokuzithandela) sisetshenziswa ezintweni zikagesi lapho izakhiwo nezindlela zokuzisebenzisa zingeke zibangele imiphumela eyingozi enkulu noma isithiyo esinjengomlilo, ukushaqeka kukagesi. Futhi ingozi nesithiyo kungavinjelwa ngokuhlola izinto zikagesi.

▍Ubani ongafaka isicelo sesitifiketi se-KC:

Bonke abantu abasemthethweni noma abantu ngabanye ekhaya naphesheya abenza umsebenzi wokukhiqiza, ukuhlanganisa, ukucubungula izinto zikagesi.

▍Isu kanye nendlela yesitifiketi sokuphepha:

Faka isicelo sesitifiketi se-KC esinemodeli yomkhiqizo engahlukaniswa ngemodeli eyisisekelo kanye nemodeli yochungechunge.

Ukuze kucaciswe uhlobo lwemodeli kanye nomklamo wezinto zikagesi, igama lomkhiqizo eliyingqayizivele lizonikezwa ngokomsebenzi wawo ohlukile.

▍ Isitifiketi se-KC sebhethri ye-Lithium

1. Izinga lesitifiketi se-KC sebhethri ye-lithium:I-KC62133:2019
2. Ububanzi bomkhiqizo wesitifiketi se-KC sebhethri ye-lithium

A. Amabhethri e-lithium yesibili azosetshenziswa kuhlelo lokusebenza oluphathekayo noma kumadivayisi akhiphekayo

B. Iseli alikho ngaphansi kwesitifiketi se-KC ukuthi liyathengiswa noma lihlanganiswe ngamabhethri.

C. Kumabhethri asetshenziswa kudivayisi yokugcina amandla noma i-UPS (ugesi ongaphazamiseki), namandla awo angaphezu kuka-500Wh angaphezu komthamo.

D. Ibhethri ubukhulu bawo amandla evolumu bungaphansi kuka-400Wh/L iza esikhaleni sesitifiketi kusukela ngo-1.^st, Ephreli 2016.

▍Kungani i-MCM?

● I-MCM igcina ukubambisana okuseduze namalebhu ase-Korea, njenge-KTR (Korea Testing & Research Institute) futhi iyakwazi ukunikeza izixazululo ezingcono kakhulu ngokusebenza kwezindleko eziphakeme kanye nesevisi Yokwengeza Inani kumakhasimende kusukela endaweni yesikhathi sokuhola, inqubo yokuhlola, ukunikezwa isitifiketi. izindleko.

● Isitifiketi se-KC sebhethri ye-lithium eshajwayo singatholwa ngokuthumela isitifiketi se-CB futhi sisiguqulele kusitifiketi se-KC. Njenge-CBTL ngaphansi kwe-TÜV Rheinland, i-MCM inganikeza imibiko nezitifiketi ezingase zisetshenziswe ekuguqulelweni kwesitifiketi se-KC ngokuqondile. Futhi isikhathi sokuhola singafinyezwa uma usebenzisa i-CB ne-KC ngesikhathi esifanayo. Ngaphezu kwalokho, intengo ehlobene izoba yinhle kakhulu.

Njengamanje, amabhethri amaningi ombuso aqinile asekelwe kumabhethri e-lithium-sulfur. 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, abacwaningi bebesebenza ekuthuthukiseni i-electrolyte kanye nokuxhumana kwebhethri yesimo esiqinile.
I-UL 1642yengeza lesi sincomo ngomgomo wokuxazulula 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.
