▍BSMI Chiyambi cha Chiphaso cha BSMI
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 ndi wovomerezeka mpaka pa 30 Epulo 2014. Cell, 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 yambiri padziko lonse lapansi kudzera munjira imodzi yosavuta.
Chitetezo cha njira yosungiramo mphamvu ndizovuta kwambiri.Monga chimodzi mwazinthu zofunika kwambiri zosungira mphamvu zamagetsi, chitetezo cha batri la lithiamu-ion ndikofunikira kwambiri.Monga kuyesa kwamphamvu kwa kutentha kumatha kuwunika mwachindunji kuopsa kwa moto wopezeka m'makina osungiramo mphamvu, mayiko ambiri apanga njira zoyeserera zofananira pamiyezo yawo kuti awone chiwopsezo cha kuthawa kwamafuta.Mwachitsanzo, IEC 62619 yoperekedwa ndi International Electrotechnical Commission (IEC) imafotokoza njira yofalitsira kuti iwunikire chikoka cha kuthawa kwa cell;Chinese national standard GB/T 36276 amafuna matenthedwe akuthawa kuwunika kwa selo ndi matenthedwe kuthawa mayeso a batire gawo;US Underwriters Laboratories (UL) imasindikiza miyezo iwiri, UL 1973 ndi UL 9540A, zonse zomwe zimayesa kuthawa kwa kutentha.UL 9540A idapangidwa mwapadera kuti iwunike kuchokera pamiyezo inayi: cell, module, cabinet, ndi kufalitsa kutentha pamlingo woika.Zotsatira za mayeso othamangitsidwa ndi kutentha sizingangoyang'ana chitetezo chonse cha batri, komanso kutilola kuti timvetsetse msanga kuthawa kwa maselo, ndikupereka magawo ofanana ndi mapangidwe a chitetezo cha maselo omwe ali ndi chemistry yofanana.Gulu lotsatira la kuyesa kwazomwe mukuthawa kutentha ndikuti mumvetsetse mawonekedwe a kuthawa kwamafuta pagawo lililonse ndi zida zomwe zili muselo.
Gawo 1: Kutentha kumakwera pang'onopang'ono ndi gwero lotenthetsera lakunja.Panthawiyi, kutentha kwa selo ndi 0 ℃ / min (0 ~ T1), selo lokha silimatenthetsa, ndipo palibe mankhwala mkati mwake.
