▍Yintoni i-cTUVus & ne-ETL CERTIFICATION?
I-OSHA (i-Occupational Safety and Health Administration), enxulumene ne-US DOL (iSebe lezeMisebenzi), inyanzelisa ukuba zonke iimveliso eziza kusetyenziswa kwindawo yokusebenza kufuneka zivavanywe kwaye ziqinisekiswe yi-NRTL ngaphambi kokuba zithengiswe emarikeni. Imigangatho yovavanyo esebenzayo ibandakanya imigangatho ye-American National Standards Institute (ANSI); Imigangatho ye-American Society for Testing Material (ASTM), imigangatho yeLabhoratri ye-Underwriter (UL), kunye nemigangatho yombutho wokuqaphela okufanayo.

▍Kutheni i-MCM?
● Inkxaso ethambileyo evela kwisiqinisekiso neteknoloji:Njengelebhu yovavanyo lwamangqina ye-TUVRH kunye ne-ITS kwiSiqinisekiso soMntla waseMelika, i-MCM iyakwazi ukwenza zonke iintlobo zovavanyo kunye nokubonelela ngenkonzo engcono ngokutshintshiselana ngetekhnoloji ubuso ngobuso.
● Inkxaso enzima evela kubuchwepheshe:I-MCM ixhotyiswe ngazo zonke izixhobo zovavanyo lweebhetri ezinkulu, ezinobungakanani obuncinci kunye neeprojekthi ezichanekileyo (oko kukuthi imoto yombane ephathwayo, amandla okugcina, kunye neemveliso zedijithali), ekwazi ukubonelela ngovavanyo lwebhetri ngokubanzi kunye neenkonzo zesatifikethi kuMntla Melika, ukugubungela imigangatho. UL2580, UL1973, UL2271, UL1642, UL2054 njalo njalo.
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 zokubaleka kwe-thermal kwinqanaba ngalinye kunye nezinto ezisesiseleni.Inqanaba lesi-3 linqanaba lokubola kwe-electrolyte (T1 ~ T2). Xa ubushushu bufikelela kwi-110℃, i-electrolyte kunye ne-electrode engalunganga, kunye ne-electrolyte ngokwayo iya kwenzeka uthotho lokusabela kokubola, ukuvelisa isixa esikhulu segesi. Igesi eqhubekayo yenza uxinzelelo ngaphakathi kwiseli lunyuke ngokukhawuleza, lufikelele kwixabiso lokunciphisa uxinzelelo, kwaye i-gas exhausting mechanism ivula (T2). Ngeli xesha, igesi eninzi, i-electrolytes kunye nezinye izinto zikhupha, zithatha indawo yobushushu, kwaye izinga lobushushu elikhulayo liba libi.
