▍Yintoni i-KC?
Ukususela kwi-25thAug., 2008，Korea Ministry of Knowledge Economy (MKE) wabhengeza ukuba National Standard Committee uya kuqhuba uphawu olutsha lwesizwe esidityanisiweyo isatifikethi - ebizwa KC uphawu endaweni Certification Korean ngexesha phakathi Jul. 2009 kunye Dec. 2010. Isiqinisekiso sokhuseleko Izixhobo zoMbane. iskimu (iSitifiketi se-KC) siskim esisisinyanzelo kunye nesizilawulayo sokuqinisekisa ukhuseleko ngokoMbane UMthetho woLawulo loKhuseleko lweZixhobo, isikim esiqinisekisa ukhuseleko kwimveliso nokuthengiswa.
Umahluko phakathi kokuqinisekiswa okunyanzelekileyo kunye nokuzilawula(ngokuzithandela)isiqinisekiso sokhuseleko:
Kulawulo olukhuselekileyo lwezixhobo zombane, isatifikethi se-KC sahlulwe ngokweziqinisekiso zokhuseleko ezinyanzelekileyo kunye nezizilawulayo (ngokuzithandela) njengohlelo lwengozi yemveliso.Izifundo zeSiqinisekiso esisiSinyanzeliso sisetyenziswa kwizixhobo zombane apho izakhiwo kunye neendlela zosetyenziso ezinokuthi zibangele. iziphumo ezinobungozi ezinzulu okanye umqobo onjengomlilo, ukutshatyalaliswa kombane. Ngelixa izifundo zokuzilawula (ngokuzithandela) zesatifikethi sokhuseleko zisetyenziswa kwizixhobo zombane apho izakhiwo kunye neendlela zokusetyenziswa zingenako ukubangela iziphumo ezinobungozi ezinzulu okanye umqobo onjengomlilo, ukutshitshiswa kombane. Kwaye ingozi kunye nomqobo unokuthintelwa ngokuvavanya izixhobo zombane.
▍ Ngubani onokufaka isicelo sesiqinisekiso se-KC:
Bonke abantu abasemthethweni okanye abantu abasekhaya nakwamanye amazwe ababandakanyeka kwimveliso, ukudibanisa, ukusetyenzwa kwesixhobo sombane.
▍ Inkqubo kunye nendlela yokuqinisekisa ukhuseleko:
Faka isicelo sesatifikethi se-KC ngemodeli yemveliso enokwahlulwa ibe yimodeli esisiseko kunye nemodeli yothotho.
Ukuze ucacise uhlobo lwemodeli kunye noyilo lwezixhobo zombane, igama elilodwa lemveliso liya kunikwa ngokwemisebenzi yalo eyahlukileyo.
▍ Isatifikethi se-KC sebhetri yeLithium
- KC isiqinisekiso umgangatho ibhetri lithium:KC62133:2019
- Umda wemveliso yesiqinisekiso se-KC sebhetri ye-lithium
A. Iibhetri ze-lithium yesibini zokusetyenziswa kwisicelo esiphathwayo okanye izixhobo ezisuswayo
B. Iseli ayixhomekekanga kwisatifikethi se-KC nokuba siyathengiswa okanye sidityaniswe kwiibhetri.
C. Kuba iibhetri ezisetyenziswa kwisixhobo sogcino lwamandla okanye i-UPS (unikezelo lwamandla olungaphazamisekiyo), kunye namandla abo angaphezu kwama-500Wh angaphaya komda.
D. Ibhetri enomthamo wamandla omthamo ungaphantsi kwe 400Wh/L ingena kumda wesatifikethi ukusukela ngo-1.st, Epreli 2016.
▍Kutheni i-MCM?
● I-MCM igcina intsebenziswano esondeleyo kunye neelebhu zaseKorea, ezifana ne-KTR (iKorea Testing & Research Institute) kwaye iyakwazi ukunika izisombululo ezingcono kakhulu kunye nokusebenza kweendleko eziphezulu kunye nenkonzo yeXabiso elongezelelweyo kubaxhasi ukusuka kwinqanaba lokukhokela, inkqubo yokuvavanya, isiqinisekiso. iindleko.
● Isiqinisekiso se-KC sebhetri ye-lithium egcwalisekayo sinokufunyanwa ngokungenisa isatifikethi se-CB kwaye sisiguqulele kwisatifikethi se-KC. Njenge-CBTL phantsi kwe-TÜV Rheinland, i-MCM inokunikezela ngeengxelo kunye nezatifikethi ezinokuthi zifake isicelo sokuguqulwa kwesatifikethi se-KC ngokuthe ngqo. Kwaye ixesha elikhokelayo linokufinyezwa ukuba usebenzisa i-CB kunye ne-KC ngaxeshanye. Ngaphezu koko, ixabiso elinxulumeneyo liya kuba lihle ngakumbi.
Ukhuseleko lwenkqubo yokugcina amandla yinkxalabo eqhelekileyo. Njengenye yezinto ezibalulekileyo zenkqubo yokugcina amandla, ukhuseleko lwebhetri ye-lithium-ion lubaluleke kakhulu. Njengoko uvavanyo lokubaleka kwe-thermal lunokuvavanya ngokuthe ngqo umngcipheko womlilo owenzeka kwinkqubo yokugcina amandla, amazwe amaninzi aphuhlise iindlela zovavanyo ezihambelanayo kwimigangatho yazo yokuvavanya umngcipheko wokubaleka kwe-thermal. Ngokomzekelo, i-IEC 62619 ekhutshwe yi-International Electrotechnical Commission (IEC) ichaza indlela yokusabalalisa ukuvavanya impembelelo ye-thermal runaway yeseli; Umgangatho wesizwe saseTshayina i-GB/T 36276 ifuna ukuvavanywa kobushushu bokufudumala kweseli kunye novavanyo lokubaleka kwe-thermal kwimodyuli yebhetri; I-US Underwriters Laboratories (UL) ipapasha imigangatho emibini, i-UL 1973 kunye ne-UL 9540A, zombini ezo zivavanya iziphumo zokubaleka kwe-thermal. I-UL 9540A yenzelwe ngokukodwa ukuvavanya kumanqanaba amane: iseli, imodyuli, ikhabhinethi, kunye nokusasazwa kobushushu kwinqanaba lofakelo. Iziphumo zovavanyo lokubaleka kwe-thermal azikwazi nje ukuvavanya ukhuseleko olupheleleyo lwebhetri, kodwa zikwavumela ukuba siqonde ngokukhawuleza ukubaleka kwe-thermal yeeseli, kunye nokubonelela ngeeparitha ezifanayo zoyilo lokhuseleko lweeseli ezinekhemistri efanayo. Eli qela lilandelayo lovavanyo lwedatha ye-thermal runaway kukuba uqonde iimpawu ze-thermal runaway kwinqanaba ngalinye kunye nezinto ezikwiseli.
Ngokokwahluka kweqondo lobushushu elibalekayo, inkqubo yahlulwe yangamanqanaba amahlanu (Umfanekiso 1 ubonisa ijiko lokutshintsha kobushushu beqela leemvavanyo zokubaleka kwe-thermal):
