▍BSMI Intshayelelo yesiqinisekiso seBSMI
I-BSMI imfutshane kwiBureau yeMigangatho, iMetrology kunye noHlolo, eyasekwa ngo-1930 kwaye yabizwa ngokuba yiNational Metrology Bureau ngelo xesha. Ingumbutho wokuhlola ophezulu kwiRiphabhlikhi yaseChina ophethe umsebenzi kwimigangatho yesizwe, i-metrology kunye nokuhlolwa kwemveliso njl.njl. Imigangatho yokuhlola izixhobo zombane eTaiwan yenziwe yi-BSMI. Iimveliso zigunyaziswe ukuba zisebenzise uphawu lwe-BSMI phantsi kweemeko ezihambelana neemfuno zokhuseleko, uvavanyo lwe-EMC kunye nezinye iimvavanyo ezinxulumene nazo.
Izixhobo zombane kunye neemveliso zombane zivavanywa ngokwezi zicwangciso zintathu zilandelayo: uhlobo oluvunyiweyo (T), ukubhaliswa kwesiqinisekiso semveliso (R) kunye nokubhengezwa kokuthotyelwa (D).
▍Uthini umgangatho weBSMI?
Nge-20 kaNovemba ka-2013, ibhengezwe yi-BSMI ukuba ukusuka kwi-1st, NgoMeyi 2014, i-3C yesibini ye-lithium cell / ibhetri, ibhanki yamandla e-lithium yesibini kunye ne-3C ishaja yebhetri ayivumelekanga ukufikelela kwimarike yaseTaiwan de ihlolwe kwaye ifaneleke ngokwemigangatho efanelekileyo (njengoko kuboniswe kwitheyibhile engezantsi).
| Udidi lweMveliso yoVavanyo | Ibhetri ye-3C yeSekondari yeLithium eneseli enye okanye ipakethe (imilo yeqhosha ayibandakanywanga) | IBhanki yaMandla yeLithium yesibini ye-3C | Itshaja yebhetri ye-3C |
Amagqabantshintshi: Inguqulelo ye-CNS 15364 1999 iyasebenza ukuya kuma-30 kuTshazimpuzi 2014. Iseli, ibhetri kunye Iselfowuni yenza uvavanyo lwamandla kuphela nge-CNS14857-2 (uguqulelo luka-2002).

▍Kutheni i-MCM?
● Kwi-2014, ibhetri ye-lithium ehlaziywayo yaba yimfuneko eTaiwan, kwaye i-MCM yaqala ukubonelela ngolwazi lwamva nje malunga nesatifikethi se-BSMI kunye nenkonzo yokuvavanya kubaxhasi behlabathi, ngakumbi abo bavela kwilizwe laseChina.
● Umgangatho wokuPasa oPhezulu:I-MCM sele incede abathengi ukuba bafumane ngaphezu kwe-1,000 lezatifikethi ze-BSMI kude kube ngoku ngexesha elinye.
● Iinkonzo ezihlanganisiweyo:I-MCM inceda abathengi ukuba bangene ngempumelelo kwiimarike ezininzi kwihlabathi liphela ngenkonzo edityanisiweyo yenkqubo elula.
Ukusasazwa kwe-thermal yemodyuli namava alandelayo: Ukuqokelelwa kobushushu emva kokusetyenziswa kakubi kwe-thermal yeseli, ukubaleka kwe-thermal yeseli kunye nokubaleka kwemodyuli ye-thermal. Ukubaleka kwe-thermal kwiseli enye akunampembelelo; nangona kunjalo, xa ubushushu busasazeka kwezinye iiseli, ukusabalalisa kuya kubangela i-domino effect, ekhokelela ekubalekeni kwe-thermal yemodyuli yonke, ukukhulula amandla amakhulu. Umzobo 1 ubonisa umphumo wovavanyo lokubaleka kwe-thermal. Imodyuli ivutha umlilo ngenxa yokusabalalisa okungenakunqandwa.I-conductivity yokushisa ngaphakathi kwiseli iya kuhluka ngokweendlela ezahlukeneyo. I-coefficient ye-conductivity yokushisa iya kuba phezulu kwi-directional parallel kunye ne-roll core yeseli; ngelixa isalathiso esithe nkqo kwi-roll core ine-conductivity ephantsi. Ke ngoko ukusasazeka kwe-thermal ukusuka kwelinye icala ukuya kwelinye phakathi kweeseli kuyakhawuleza kunokuba kwenzayo ngeethebhu ukuya kwiiseli. Ngoko ke, ukusasaza kunokubonwa njengokusasazwa komlinganiselo omnye. Njengoko iimodyuli zebhetri ziyilelwe ukuxinana kwamandla aphezulu, indawo phakathi kweeseli iya isiba ncinci, nto leyo eya kwenza ukwanda kobushushu. Ngoko ke, ukucinezela okanye ukuthintela ukusasazeka kobushushu kwimodyuli kuya kuthathwa njengendlela esebenzayo yokunciphisa iingozi.Sinokuthintela i-runaway ye-thermal ngenkuthalo okanye i-passively.1) Setha imibhobho yokupholisa phantsi okanye emacaleni angaphakathi emodyuli, kwaye ugcwalise. ngolwelo lokupholisa. Ukuhamba kolwelo olupholisayo kunokunciphisa ngokufanelekileyo ukwanda.
