▍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).
| Isigaba somkhiqizo sokuhlola | Ibhethri le-3C Lesibili Lithium elineseli eyodwa noma iphakethe (umumo wenkinobho awufakiwe) | I-3C Secondary Lithium Power Bank | Ishaja yebhethri ye-3C |
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 amakhasimende ukuthi angene ngempumelelo ezimakethe eziningi emhlabeni jikelele ngokusebenzisa isevisi yenqwaba yesitophu esisodwa yenqubo elula.
Amazinga okushisa okuhlola ahlukile. I-IEC 62620:2014 kanye ne-JIS C 8715-1:2018ilawula izinga lokushisa elingu-5℃ eliphezulu kune-IEC 61960-3:2017. Ukushisa okuphansi kuzokwenza kube ne-viscosity ephakeme ye-electrolyte, okuzobangela ukunyakaza okuphansi kwama-ion. Ngakho-ke ukusabela kwamakhemikhali kuzohamba kancane, futhi ukumelana ne-Ohm kanye nokumelana ne-polarization kuzoba kukhudlwana, okuzobangela ukuthambekela kokunyuka kwe-DCIR.I-SoC ihlukile. I-SoC edingekayo ku-IEC 62620:2014 kanye ne-JIS C 8715-1:2018 ingu-50±10％, kuyilapho i-IEC 61960-3:2017 ingu-100%. Isimo sokukhokhiswa sinomthelela omkhulu ku-DCIR. Ngokuvamile umphumela wokuhlola we-DCIR uzokwehla ngokunyuka kwe-SoC. Lokhu kuhlobene nenqubo yokusabela. Ku-SoC ephansi, ukumelana nokudluliswa kwe-Rct kuzoba phezulu; futhi i-Rct izokwehla ngokunyuka kwe-SoC, ngakho-ke njengoba i-DCIR.Isikhathi sokukhipha sihlukile. I-IEC 62620:2014 kanye ne-JIS C 8715-1:2018 idinga isikhathi eside sokukhipha kune-IEC 61960-3:2017. Isikhathi eside sokushaya kwenhliziyo sizodala ukuthambekela okwandayo okuphansi kwe-DCIR, futhi siveze ukuchezuka emugqeni womugqa. Isizathu siwukuthi ukwanda kwesikhathi se-pulse kuzodala i-Rct ephakeme futhi ibe yinkosi.Imisinga yokukhishwa ihlukile. Kodwa-ke amandla okukhipha awahlobene ngokuqondile ne-DCIR. Ukuhlobana kunqunywa umklamo.Nakuba i-JIS C 8715-1:2018 ibhekisela ku-IEC 62620:2014, inezincazelo ezihlukile kumabhethri anesilinganiso esiphezulu. I-IEC 62620:2014 ichaza ukuthi amabhethri anesilinganiso esiphezulu angakhipha okungaphansi kuka-7.0C wamanje. Ngenkathi i-JIS C 8715-1:2018 ichaza amabhethri anesilinganiso esiphezulu yilawo angaphuma ngo-3.5C.
