▍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.
Ukuphepha kwesistimu yokugcina amandla kuyinto evamile. Njengenye yezingxenye ezibalulekile zesistimu yokugcina amandla, ukuphepha kwebhethri ye-lithium-ion kubaluleke kakhulu. Njengoba ukuhlolwa kokubaleka okushisayo kungahlola ngokuqondile ingozi yomlilo oyenzeka kusistimu yokugcina amandla, amazwe amaningi asungule izindlela zokuhlola ezihambisanayo kumazinga awo ukuze kuhlolwe ingozi yokubaleka okushisayo. Isibonelo, i-IEC 62619 ekhishwe yi-International Electrotechnical Commission (IEC) ibeka indlela yokusabalalisa yokuhlola umthelela wokubaleka okushisayo kweseli; Izinga lezwe laseShayina le-GB/T 36276 lidinga ukuhlolwa kokushisa okushisayo kweseli nokuhlolwa kokushisa okushisayo kwemojuli yebhethri; I-US Underwriters Laboratories (UL) ishicilela amazinga amabili, i-UL 1973 kanye ne-UL 9540A, womabili ahlola imiphumela yokushisa okushisayo. I-UL 9540A yakhelwe ngokukhethekile ukuhlola kusuka kumazinga amane: iseli, imojula, ikhabethe, nokusabalalisa ukushisa ezingeni lokufaka. Imiphumela yokuhlolwa kwe-thermal runnaway ayikwazi nje ukuhlola ukuphepha kukonke kwebhethri, kodwa futhi isivumela ukuthi siqonde ngokushesha ukugijima kwamaseli, futhi inikeze imingcele eqhathanisekayo yomklamo wokuphepha wamaseli anamakhemikhali afanayo. Iqembu elilandelayo lokuhlola idatha yokubaleka okushisayo elokuthi uqonde izici zokubaleka okushisayo esigabeni ngasinye nezinto ezikuseli.
Isigaba 1: Izinga lokushisa liyenyuka kancane kancane ngomthombo wangaphandle wokushisisa. Ngalesi sikhathi, izinga lokukhiqiza ukushisa kweseli ngu-0℃/min (0~ T1), iseli ngokwalo alishisi, futhi akukho ukusabela kwamakhemikhali ngaphakathi.
