▍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.
Ukuvavanya amaqondo obushushu ahlukile. I-IEC 62620: 2014 kunye ne-JIS C 8715-1: 2018ilawula i-5℃ ephezulu yobushushu be-ambient kune-IEC 61960-3:2017. Ukushisa okuphantsi kuya kuyenza ibe yi-viscosity ephezulu ye-electrolyte, eya kubangela ukunyakaza okuphantsi kweeyoni. Ngaloo ndlela ukusabela kweekhemikhali kuya kucotha, kwaye ukuxhathisa kwe-Ohm kunye nokuchasana kwe-polarization kuya kuba kukhulu, okuya kubangela umkhwa wokunyuka kwe-DCIR.I-SoC iyahluka. I-SoC efunekayo kwi-IEC 62620: 2014 kunye ne-JIS C 8715-1: 2018 yi-50％±10％, ngelixa i-IEC 61960-3: 2017 yi-100%. Ubume bentlawulo bunefuthe elikhulu kwi-DCIR. Ngokwesiqhelo iziphumo zovavanyo lwe-DCIR ziyakwehla ngokunyuka kwe-SoC. Oku kuhambelana nenkqubo yokusabela. Kwi-SoC ephantsi, ukuchasana kokudluliselwa kwentlawulo ye-Rct kuya kuba phezulu; kwaye i-Rct iya kuncipha ngokunyuka kwe-SoC, ngoko ke i-DCIR.Ixesha lokukhutshwa lihlukile. I-IEC 62620: 2014 kunye ne-JIS C 8715-1: 2018 idinga ixesha elide lokukhupha kune-IEC 61960-3: 2017. Ixesha elide lokubetha kwe-pulse liya kubangela ukunyuka okusezantsi kwe-DCIR, kwaye kubonise ukutenxa kumgca. Isizathu kukuba ukunyuka kwexesha le-pulse kuya kubangela i-Rct ephezulu kwaye ibe yinto elawulayo.Imijelo yokukhupha iyahluka. Nangona kunjalo ukukhutshwa kombane akuhambelani ngokuthe ngqo ne-DCIR. Ubudlelwane bunqunywe yi-design.Nangona i-JIS C 8715-1: i-2018 ibhekisela kwi-IEC 62620: 2014, ineenkcazo ezahlukeneyo kwiibhetri eziphezulu. I-IEC 62620: 2014 ichaza ukuba iibhetri eziphezulu ezilinganisiweyo zinokukhupha ngaphantsi kwe-7.0C yangoku. Ngelixa i-JIS C 8715-1: i-2018 ichaza iibhetri ezilinganisiweyo eziphezulu zezo zinokukhupha nge-3.5C.
