▍ Vietnam MIC Certification

Circular 42/2016/TT-BTTTT inanena kuti mabatire omwe amaikidwa m'mafoni a m'manja, mapiritsi ndi zolembera saloledwa kutumizidwa ku Vietnam pokhapokha ngati ali pansi pa certifctaion ya DoC kuyambira Oct.1,2016. DoC idzafunikanso kupereka mukamagwiritsa ntchito Chivomerezo cha Mtundu pazinthu zomaliza (mafoni a m'manja, mapiritsi ndi zolemba).

MIC inatulutsa Circular 04/2018/TT-BTTTT yatsopano mu May,2018 yomwe imati palibenso lipoti la IEC 62133:2012 loperekedwa ndi labotale yovomerezeka ya kutsidya kwa nyanja lomwe likuvomerezedwa mu July 1, 2018. Mayeso am'deralo ndi ofunikira pamene mukufunsira satifiketi ya ADoC.

▍ Mulingo Woyesera

QCVN101: 2016/BTTTT(nenani ku IEC 62133:2012)

▍PQIR

Boma la Vietnam linapereka lamulo latsopano No. 74/2018 / ND-CP pa Meyi 15, 2018 lonena kuti mitundu iwiri ya zinthu zomwe zimatumizidwa ku Vietnam zimayenera kutumizidwa ku PQIR (Product Quality Inspection Registration) potumizidwa ku Vietnam.

Kutengera lamuloli, Unduna wa Zachidziwitso ndi Kulumikizana (MIC) waku Vietnam udapereka chikalata chovomerezeka cha 2305/BTTTT-CVT pa Julayi 1, 2018, chonena kuti zinthu zomwe zili pansi pa ulamuliro wake (kuphatikiza mabatire) ziyenera kutumizidwa ku PQIR zikamatumizidwa kunja. ku Vietnam. SDoC idzaperekedwa kuti amalize ndondomeko yololeza kasitomu. Tsiku lovomerezeka la lamuloli ndi August 10, 2018. PQIR ikugwiritsidwa ntchito potumiza ku Vietnam kamodzi kokha, ndiko kuti, nthawi iliyonse woitanitsa katundu wochokera kunja, adzapempha PQIR (batch inspection) + SDoC.

Komabe, kwa ogulitsa kunja omwe akufulumira kuitanitsa katundu popanda SDOC, VNTA idzatsimikizira PQIR kwakanthawi ndikuwongolera chilolezo cha kasitomu. Koma obwera kunja akuyenera kutumiza SDoC ku VNTA kuti amalize ntchito yonse yololeza katundu mkati mwa masiku 15 ogwira ntchito pambuyo pa chilolezo cha kasitomu. (VNTA siperekanso ADOC yapitayi yomwe imagwira ntchito kwa Vietnam Local Manufacturers okha)

▍Chifukwa chiyani MCM?

● Wogawana Zambiri Zaposachedwa

● Co-founder of Quacert battery test laboratory

MCM motero imakhala wothandizira yekha labu iyi ku Mainland China, Hong Kong, Macau ndi Taiwan.

● Utumiki wa One-stop Agency Service

MCM, bungwe loyenera kuyimitsa kamodzi, limapereka kuyesa, ziphaso ndi ntchito za ma agent kwa makasitomala.

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.
