Nkhani yaMtengo wa UL1642mtundu watsopano wosinthidwa - Mayeso owonjezera owonjezera a cell cell,
Mtengo wa UL1642,

▍ 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-BTTT 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. Kuyesa kwanuko n'kofunika 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 olowa kunja akuyenera kutumiza SDoC ku VNTA kuti amalize ntchito yonse yololeza katundu mkati mwa masiku 15 ogwira ntchito pambuyo pa chilolezo cha kasitomu. (VNTA sidzatulutsanso 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.

Mtundu watsopano wa UL 1642 unatulutsidwa. Njira ina yoyesera zolemetsa imawonjezedwa pama cell athumba. Zofunikira zenizeni ndi izi: Kwa cell cell yokhala ndi mphamvu yopitilira 300 mAh, ngati mayeso olemera sanadutse, atha kuyesedwa ndi Gawo 14A mozungulira ndodo yoyeserera.
Selo la thumba lilibe vuto lolimba, lomwe nthawi zambiri limabweretsa kuphulika kwa ma cell, kuthyoka kwa ma tap, zinyalala zomwe zimawulukira kunja ndi kuwonongeka kwina kwakukulu komwe kumachitika chifukwa cholephera kuyeserera kwakukulu, ndipo zimapangitsa kuti zikhale zosatheka kuzindikira dera lalifupi lamkati lomwe limayambitsidwa ndi vuto la kapangidwe kake kapena kuwonongeka kwa dongosolo. . Ndi kuyesa kozungulira ndodo, zolakwika zomwe zingatheke mu cell zitha kudziwika popanda kuwononga ma cell. Kuwunikiridwaku kudapangidwa poganizira izi. Ikani chitsanzo pamalo athyathyathya. Ikani ndodo yozungulira yachitsulo yokhala ndi mainchesi 25 ± 1mm ​​pamwamba pa chitsanzo. Mphepete mwa ndodo iyenera kugwirizanitsidwa ndi pamwamba pa nsonga ya selo, ndi chigawo choyima cha perpendicular to tabu (FIG. 1). Utali wa ndodo uyenera kukhala wosachepera 5mm m'lifupi kuposa m'mphepete mwachitsanzo choyesera. Kwa ma cell okhala ndi ma tabo abwino ndi oyipa mbali zotsutsana, mbali iliyonse ya tabu iyenera kuyesedwa. Mbali iliyonse ya tabu iyenera kuyesedwa pazitsanzo zosiyanasiyana.  Kuyeza makulidwe (kulolera ± 0.1mm) kwa maselo kumayenera kuchitidwa asanayesedwe molingana ndi Zowonjezera A za IEC 61960-3 (Maselo achiwiri ndi mabatire omwe ali ndi alkaline kapena ena omwe si- ma electrolyte acidic - Ma cell achiwiri a lithiamu ndi mabatire - Gawo 3: Ma cell a prismatic ndi cylindrical lithiamu sekondale ndi mabatire
