▍BSMI Mau oyamba a BSMI certification
BSMI ndiyofupika ku Bureau of Standards, Metrology and Inspection, yomwe idakhazikitsidwa mu 1930 ndipo idatchedwa National Metrology Bureau panthawiyo. Ndilo bungwe lapamwamba kwambiri loyang'anira zinthu ku Republic of China lomwe limayang'anira ntchito zoyendera dziko lonse, metrology ndi kuyang'anira zinthu ndi zina. Miyezo yoyendera zida zamagetsi ku Taiwan imakhazikitsidwa ndi BSMI. Zogulitsa ndizololedwa kugwiritsa ntchito chizindikiro cha BSMI pamikhalidwe yomwe ikutsatira zofunikira zachitetezo, kuyesa kwa EMC ndi mayeso ena okhudzana nawo.
Zida zamagetsi ndi zamagetsi zimayesedwa molingana ndi njira zitatu izi: zovomerezeka zamtundu (T), kulembetsa certification yazinthu (R) ndi Declaration of Conformity (D).
▍Kodi muyezo wa BSMI ndi wotani?
Pa 20 November 2013, adalengezedwa ndi BSMI kuti kuchokera ku 1st, May 2014, 3C yachiwiri lifiyamu selo / batire, sekondale lithiamu mphamvu banki ndi 3C batire naupereka saloledwa kupeza msika Taiwan mpaka iwo anayendera ndi oyenerera malinga ndi mfundo zoyenera (monga taonera m'munsimu).

Ndemanga: Mtundu wa CNS 15364 1999 umagwira ntchito mpaka pa 30 Epulo 2014. Selo, batire ndi Mafoni amangoyesa mayeso a CNS14857-2 (2002 version).

▍Chifukwa chiyani MCM?
● Mu 2014, batire ya lithiamu yowonjezereka inakhala yovomerezeka ku Taiwan, ndipo MCM inayamba kupereka zidziwitso zaposachedwa za certification ya BSMI ndi ntchito yoyesera kwa makasitomala apadziko lonse, makamaka ochokera ku China.
● Kukwera Kwambiri:MCM yathandiza kale makasitomala kupeza ziphaso zopitilira 1,000 za BSMI mpaka pano nthawi imodzi.
● Ntchito zophatikizika:MCM imathandiza makasitomala kulowa bwino m'misika ingapo padziko lonse lapansi kudzera munjira imodzi yosavuta.
UL 1973:2022 idasindikizidwa pa 25 February. Mtunduwu umachokera pamalingaliro awiri omwe adaperekedwa mu Meyi ndi Okutobala 2021. Mulingo wosinthidwa umakulitsa kuchuluka kwake, kuphatikiza makina othandizira mphamvu zamagalimoto (mwachitsanzo, kuwunikira ndi kulumikizana).
Zowonjezera 7.7 Transformer: thiransifoma ya makina a batri iyenera kukhala ndi satifiketi pansi pa UL 1562 ndi UL 1310 kapena milingo yoyenera. Mphamvu yotsika imatha kutsimikiziridwa pansi pa 26.6.
Kusintha 7.9: Mayendedwe Oteteza ndi Kuwongolera: makina a batri adzapereka chosinthira kapena chosweka, chocheperako chomwe chimafunikira kukhala 60V m'malo mwa 50V. Zofunikira zowonjezera pakuwongolera ma fuse opitilira muyeso Kusintha Ma cell 7.12 (mabatire ndi electrochemical capacitor): Pama cell a Li-ion omwe amatha kuchargeable, kuyesa pansi pa Annex E ndikofunikira, osaganizira za UL 1642. monga zakuthupi ndi malo a insulator, kuphimba anode ndi cathode, etc.
Onjezani 16 Mtengo Wokwera Kwambiri: Unikani chitetezo chacharge ya makina a batri omwe ali ndi kuchuluka kopitilira apo. Muyenera kuyesa mu 120% ya kuchuluka kwa ndalama zolipiritsa.
Onjezani 18 Pakuchulukira Pansi Pakutha: Yang'anani mphamvu yamakina a batri ndikuchulukira pansi. Pali zikhalidwe ziwiri zoyezetsa: choyamba ndi chodzaza kwambiri pansi pa kutayidwa kumene panopa ndipamwamba kuposa momwe amachitira pakalipano koma otsika kuposa panopa a chitetezo cha BMS overcurrent; yachiwiri ndi yapamwamba kuposa BMS pachitetezo chapano koma chotsika kuposa 1 chitetezo chapano.
