▍ 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.

Mu 1800, katswiri wa sayansi ya zakuthambo wa ku Italy A. Volta anamanga mulu wa voltaic, womwe unatsegula chiyambi cha mabatire othandiza ndikufotokozera kwa nthawi yoyamba kufunika kwa electrolyte mu zipangizo zosungiramo mphamvu zamagetsi. Electrolyte imatha kuwonedwa ngati yosanjikiza pakompyuta ndi ion-conducting mu mawonekedwe amadzimadzi kapena olimba, oyikidwa pakati pa ma elekitirodi oyipa ndi abwino. Panopa, electrolyte kwambiri patsogolo amapangidwa Kusungunuka olimba lifiyamu mchere (mwachitsanzo LiPF6) mu sanali amadzimadzi organic carbonate zosungunulira (mwachitsanzo EC ndi DMC). Malinga ndi mawonekedwe a cell ndi kapangidwe kake, ma electrolyte nthawi zambiri amakhala 8% mpaka 15% ya kulemera kwa selo. Kuonjezera apo, kuyaka kwake ndi kutentha kwapakati pa -10 ° C mpaka 60 ° C kumalepheretsa kwambiri kusintha kwa mphamvu ya batri ndi chitetezo. Choncho, njira zatsopano za electrolyte zimaonedwa kuti ndizofunikira kwambiri pa chitukuko cha m'badwo wotsatira wa mabatire atsopano.Ofufuza akugwiranso ntchito kuti apange machitidwe osiyanasiyana a electrolyte. Mwachitsanzo, kugwiritsa ntchito zosungunulira fluorinated kuti angathe kukwaniritsa imayenera lifiyamu zitsulo njinga, organic kapena zosawerengeka olimba electrolytes kuti phindu makampani galimoto ndi "olimba boma mabatire" (SSB). Chifukwa chachikulu ndi chakuti ngati electrolyte olimba m'malo choyambirira madzi electrolyte ndi diaphragm, chitetezo, limodzi mphamvu kachulukidwe ndi moyo wa batire akhoza kwambiri bwino. Kenako, timafotokozera mwachidule kafukufuku wa ma electrolyte olimba omwe ali ndi zinthu zosiyanasiyana. Ma electrolyte olimba a inorganic akhala akugwiritsidwa ntchito m'zida zosungiramo mphamvu zamagetsi zamagetsi, monga mabatire ena omwe amatha kuwiritsanso kutentha kwambiri Na-S, Na-NiCl2 mabatire ndi mabatire oyamba a Li-I2. . Kale mu 2019, Hitachi Zosen (Japan) adawonetsa batire la thumba lolimba kwambiri la 140 mAh kuti ligwiritsidwe ntchito mumlengalenga ndikuyesedwa pa International Space Station (ISS). Batire iyi imapangidwa ndi sulfide electrolyte ndi zigawo zina za batri zosadziwika, zomwe zimatha kugwira ntchito pakati pa -40°C ndi 100°C. Mu 2021 kampaniyo ikubweretsa batire yolimba kwambiri ya 1,000 mAh. Hitachi Zosen akuwona kufunikira kwa mabatire olimba m'malo ovuta monga malo ndi zida zamafakitale zomwe zimagwira ntchito m'malo wamba. Kampaniyo ikukonzekera kuwirikiza kawiri mphamvu ya batri pofika chaka cha 2025. Koma mpaka pano, palibe mankhwala a batri olimba omwe angagwiritsidwe ntchito pamagalimoto amagetsi.
