▍BSMI Isingeniso Isingeniso se-BSMI
I-BSMI imfushane nge-Bureau of Standards, Metrology and Inspection, eyasungulwa ngo-1930 futhi yabizwa ngeNational Metrology Bureau ngaleso sikhathi. Kuyinhlangano ephakeme yokuhlola eRiphabhulikhi yaseShayina ephethe umsebenzi kumazinga kazwelonke, i-metrology nokuhlolwa komkhiqizo njll. Amazinga okuhlolwa kwezinto zikagesi e-Taiwan agunyazwa yi-BSMI. Imikhiqizo igunyaziwe ukusebenzisa ukumaka kwe-BSMI ezimeni lapho ithobelana nezidingo zokuphepha, ukuhlolwa kwe-EMC nokunye ukuhlola okuhlobene.
Izinto zikagesi kanye nemikhiqizo ye-elekthronikhi ihlolwa ngokwalezi zinhlelo ezintathu ezilandelayo: uhlobo olugunyazwe (T), ukubhaliswa kwesitifiketi somkhiqizo (R) kanye nesimemezelo sokuvumelana (D).
▍Liyini izinga le-BSMI?
Ngomhla zingama-20 kuNovemba 2013, kumenyezelwe yi-BSMI ukuthi kusuka ku-1st, Meyi 2014, iseli/ibhethri le-3C lesibili le-lithium, ibhange lamandla e-lithium yesibili kanye neshaja yebhethri engu-3C azivunyelwe ukufinyelela emakethe yase-Taiwan zize zihlolwe futhi zifaneleke ngokuya ngamazinga afanele (njengoba kuboniswe kuthebula elingezansi).

Amazwana: Inguqulo ye-CNS 15364 1999 isebenza kuze kube umhla zingama-30 kuMbasa 2014. Iseli, ibhethri kanye Iselula yenza ukuhlolwa komthamo kuphela nge-CNS14857-2 (inguqulo ka-2002).

▍Kungani i-MCM?
● Ngo-2014, ibhethri ye-lithium ekwazi ukushajwa kabusha yaba isibopho e-Taiwan, futhi i-MCM yaqala ukunikeza ulwazi lwakamuva mayelana nesitifiketi se-BSMI kanye nesevisi yokuhlola kumakhasimende omhlaba, ikakhulukazi lawo avela ezweni lase-China.
● Izinga eliphezulu lokudlula:I-MCM isivele isisize amakhasimende ukuthi athole izitifiketi ze-BSMI ezingaphezu kuka-1,000 kuze kube manje ngesikhathi esisodwa.
● Amasevisi ahlanganisiwe:I-MCM isiza amaklayenti ukuthi angene ngempumelelo ezimakethe eziningi emhlabeni wonke ngokusebenzisa isevisi ehlanganisiwe yokuma eyodwa yenqubo elula.
Ubuchwepheshe bokushabalalisa ukushisa kwebhethri, obubizwa nangokuthi ubuchwepheshe bokupholisa, empeleni kuyinqubo yokushintshanisa ukushisa eyehlisa izinga lokushisa langaphakathi lebhethri ngokudlulisela ukushisa kusuka kubhethri kuya endaweni yangaphandle ngokusebenzisa indawo yokupholisa. okwamanje isetshenziswa ngezinga elikhulu kumabhethri okudonsa. , kanye namabhethri okugcina amandla, ikakhulukazi lawo esitsha se-ESS. Amabhethri e-Li-ion azwela kakhulu kuzinga lokushisa njengama-catalysts amakhemikhali ekusetshenzisweni kwangempela. Ngakho-ke inhloso yokukhipha ukushisa ukuhlinzeka ngezinga lokushisa elifanele lebhethri. Uma izinga lokushisa lebhethri le-Li-ion liphezulu kakhulu, uchungechunge lokusabela oseceleni njengokubola kwefilimu eqinile ye-electrolyte interface (ifilimu ye-SEI) kuzokwenzeka ngaphakathi kwebhethri, okuthinta kakhulu umjikelezo wempilo yebhethri. Kodwa-ke, uma izinga lokushisa liphansi kakhulu, ukusebenza kwebhethri kuzoguga ngokushesha futhi kube khona ingozi yemvula ye-lithium, eholela ekunciphiseni ngokushesha umthamo wokukhipha kanye nokusebenza okulinganiselwe ezindaweni ezibandayo. Ngaphezu kwalokho, umehluko wezinga lokushisa phakathi kweseli elilodwa kumojuli nakho kuyisici okungafanele sizitshwe. Umehluko wezinga lokushisa ongaphezu kwebanga elithile uzoholela ekushajelweni kwangaphakathi okungalingani kanye nokukhipha, okuholela ekuchezukeni komthamo. Ukwengeza, umehluko wokushisa uzophinde uholele ekwenyukeni kwezinga lokukhiqiza ukushisa kwamaseli eduze kwendawo yokulayisha, okuholela ekuhlulekeni kwebhethri.Kweminye imikhiqizo yezinga eliphakathi nendawo eliphezulu, ngenxa yokushaja okuphezulu nokukhipha amandla, ukushisa ngaphakathi. imojula ayikwazi ukuchithwa ngokushesha nangempumelelo ngokupholisa kwemvelo kuphela, njengoba kuzodala kalula ukuqoqwa kokushisa ngaphakathi futhi kuthinte impilo yomjikelezo wamaseli. Ngakho-ke, indlela yokupholisa umoya ephoqelelwe ifaneleka kakhulu esimweni sokusetshenziswa kwemikhiqizo yokugcina amandla esezingeni eliphakathi neliphezulu.
