▍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.
UL 1973:2022 yapapashwa nge-25 kaFebruwari. Olu guqulelo lusekwe kwidrafti yeengcebiso ezimbini ezikhutshwe ngoMeyi nango-Okthobha ka-2021. Umgangatho olungisiweyo wandisa uluhlu lwayo, kubandakanywa inkqubo yamandla yomncedisi wesithuthi (umzekelo, ukukhanya kunye nonxibelelwano).
Isihlomelo 7.7 Isiguquli: isiguquli senkqubo yebhetri siya kuqinisekiswa phantsi kwe-UL 1562 kunye ne-UL 1310 okanye imigangatho efanelekileyo. Amandla ombane aphantsi anokuqinisekiswa phantsi kwe-26.6.
Uhlaziyo lwe-7.9: IiSekethe eziKhuselekileyo kunye noLawulo: inkqubo yebhetri iya kubonelela ngokutshintsha okanye i-breaker, ubuncinane obufunekayo ukuba ibe yi-60V endaweni ye-50V. Imfuneko eyongezelelweyo yomyalelo we-overcurrent fuse Hlaziya 7.12 Iiseli (iibhetri kunye ne-electrochemical capacitor): Kwiiseli ze-Li-ion ezitshajekayo, uvavanyo phantsi kwesihlomelo E lufunekayo, ngaphandle kokuqwalasela i-UL 1642. njengezinto eziphathekayo kunye nesikhundla se-insulator, ukugubungela i-anode kunye ne-cathode, njl.
Fakela iRhafu yeRhafu ePhakamileyo ye-16: Vavanya ukhuseleko lokutshaja lwesixokelelwano sebhetri enobuninzi bokutshaja bangoku. Kufuneka kuvavanywe nge-120% yezinga eliphezulu lokutshaja.
Fakela i-18 yokuNxibelela phantsi koKhuphiswayo: Vavanya amandla enkqubo yebhetri ngomthwalo ogqithisileyo phantsi kokukhutshelwa. Kukho iimeko ezimbini zovavanyo: okokuqala kumthwalo ogqithisiweyo phantsi kokukhutshwa apho ikhoyo iphezulu kunomlinganiselo ophezulu wokukhupha okwangoku kodwa ungaphantsi kwe-BMS yokukhusela ngokugqithisileyo; okwesibini kuphezulu kune-BMS ngaphezu kokukhuselwa kwangoku kodwa ngaphantsi kwinqanaba le-1 lokukhusela okwangoku.
