Uvavanyo lweDatha yeCell Thermal Runaway kunye noHlahlelo lweIrhasiImveliso,
Irhasi,

▍Isiqinisekiso se-MIC saseVietnam

ISetyhula 42/2016/TT-BTTTT ichaze ukuba iibhetri ezifakwe kwiifowuni eziphathwayo, iitafile kunye neencwadana zokubhalela azivumelekanga ukuba zithunyelwe eVietnam ngaphandle kokuba ziphantsi kwe-DoC certifctaion ukususela ngo-Oct.1,2016. I-DoC iya kuphinda ifuneke ukuba ibonelele xa ifaka isicelo sokuVunywa koHlobo lweemveliso zokuphela konyaka (iimfonomfono eziphathwayo, iitafile kunye neencwadana).

I-MIC ikhuphe iSetyhula entsha ye-04/2018/TT-BTTT ngoMeyi, i-2018 echaza ukuba akukho ngxelo ye-IEC 62133:2012 ekhutshwe yilabhoratri evunyiweyo yaphesheya yamkelwa ngoJulayi 1, 2018. Uvavanyo lwendawo luyimfuneko ngelixa ufaka isicelo sesatifikethi se-ADoC.

▍Umgangatho woVavanyo

QCVN101:2016/BTTT(bhekisa kwi-IEC 62133:2012)

▍PQIR

Urhulumente waseVietnam ukhuphe umyalelo omtsha onguNombolo 74/2018 / ND-CP ngoMeyi 15, 2018 ukuba uchaze ukuba iintlobo ezimbini zeemveliso ezingeniswe eVietnam zixhomekeke kwi-PQIR (Ukubhaliswa kokuHlolwa koMgangatho weMveliso) xa zithunyelwa eVietnam.

Ngokusekelwe kulo mthetho, i-Ofisi yoLwazi kunye noNxibelelwano (MIC) yaseVietnam ikhuphe uxwebhu olusemthethweni lwe-2305/BTTTT-CVT ngoJulayi 1, 2018, oluchaza ukuba iimveliso eziphantsi kolawulo lwayo (kubandakanywa neebhetri) kufuneka zifakwe kwi-PQIR xa zithunyelwa ngaphandle. ukuya eVietnam. I-SDoC iya kungeniswa ukuze igqibezele inkqubo yokukhutshwa kwempahla ekhoyo. Umhla osemthethweni wokungena ekusebenzeni kwalo mmiselo ngo-Agasti 10, 2018. I-PQIR isetyenziswa ekungeniseni enye eVietnam, oko kukuthi, rhoqo xa umthengisi engenisa iimpahla, uya kufaka isicelo se-PQIR (ukuhlolwa kwebhetshi) + SDoC.

Nangona kunjalo, kubarhwebi abangxamisekileyo ukuba bangenise iimpahla ngaphandle kwe-SDOC, i-VNTA iya kuqinisekisa okwethutyana i-PQIR kwaye iququzelele ukukhutshwa kwempahla. Kodwa abathumeli bangaphandle kufuneka bangenise i-SDoC kwi-VNTA ukuze igqibezele inkqubo yokukhutshwa kwempahla ngaphandle kwempahla ngaphakathi kwe-15 leentsuku zokusebenza emva kokukhutshwa kwempahla ephumayo. (I-VNTA ayisayi kuphinda ikhuphe i-ADOC yangaphambili esebenza kuphela kwi-Vietnam Local Manufacturers)

▍Kutheni i-MCM?

● Umxhasi woLwazi lwamva nje

● Umseki wegumbi lovavanyo lwebhetri yeQuacert

I-MCM ngoko iba yeyona arhente ikuphela kwayo yale lebhu e-Mainland China, eHong Kong, eMacau naseTaiwan.

● Inkonzo ye-Arhente yokuma enye

I-MCM, i-arhente efanelekileyo yokumisa enye, ibonelela ngovavanyo, isatifikethi kunye nenkonzo ye-arhente kubathengi.

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.
Inqanaba 1: Iqondo lobushushu liyenyuka ngokuthe ngcembe kunye nomthombo wokufudumeza wangaphandle. Ngeli xesha, izinga lokuvelisa ukushisa kweseli yi-0 ℃ / min (0 ~ T1), iseli ngokwayo ayishushu, kwaye akukho ukuphendula kweekhemikhali ngaphakathi.
