▍Vietnam MIC palapala hōʻoia

Ua ʻōlelo ʻo Circular 42/2016/TT-BTTTT ʻaʻole ʻae ʻia nā pihi i hoʻokomo ʻia i loko o nā kelepona paʻalima, nā papa a me nā puke puke e hoʻokuʻu ʻia i Vietnam ke ʻole lākou e kau ʻia i ka palapala hōʻoia DoC mai ʻOkakopa 1,2016. Pono ʻia ʻo DoC e hāʻawi i ka wā e noi ana i ka Type Approval no nā huahana hope (kelepona paʻa, papa a me nā puke puke).

Ua hoʻokuʻu ʻo MIC i ka Circular 04/2018/TT-BTTTT hou i Mei, 2018 e ʻōlelo nei ʻaʻole i ʻae ʻia ka hōʻike IEC 62133: 2012 i hoʻopuka ʻia e nā ʻoihana i ʻae ʻia i waho ma Iulai 1, 2018.

▍Maʻamau hoʻāʻo

QCVN101:2016/BTTTT (e nānā iā IEC 62133:2012)

▍PQIR

Ua hoʻopuka ke aupuni Vietnamese i kahi kauoha hou No. 74/2018 / ND-CP ma Mei 15, 2018 e ʻōlelo ai he ʻelua ʻano huahana i lawe ʻia mai i Vietnam ma lalo o ka noi PQIR (Product Quality Inspection Registration) i ka wā e lawe ʻia mai ai i Vietnam.

Ma muli o kēia kānāwai, ua hoʻopuka ka Ministry of Information and Communication (MIC) o Vietnam i ka palapala mana 2305/BTTTT-CVT ma Iulai 1, 2018, e kuhikuhi ana i nā huahana ma lalo o kāna mana (me nā ʻāpana) pono e noi no PQIR i ka wā e lawe ʻia mai ai. i loko o Vietnam. E waiho ʻia ʻo SDoC no ka hoʻopau ʻana i ke kaʻina hana hoʻomaʻemaʻe dute. ʻO ka lā kūhelu o ke komo ʻana i ka mana o kēia hoʻoponopono ʻo ʻAukake 10, 2018. Pili ʻia ka PQIR i hoʻokahi lawe ʻia mai i Vietnam, ʻo ia hoʻi, i kēlā me kēia manawa e hoʻokomo ai ka mea lawe mai i nā waiwai, e noi ʻo ia no PQIR (batch inspection) + SDoC.

Eia nō naʻe, no ka poʻe lawe mai e koi wikiwiki nei e hoʻokomo i nā waiwai me ka ʻole o SDOC, e hōʻoia ʻo VNTA i ka PQIR no ka manawa pōkole a hoʻomaʻamaʻa i ka ʻae ʻana i nā dute. Akā, pono nā mea lawe mai e hoʻouna i ka SDoC iā VNTA e hoʻopau i ke kaʻina hana hoʻomaʻemaʻe kūʻai holoʻokoʻa i loko o 15 mau lā hana ma hope o ka ʻae ʻana i ka dute. (ʻAʻole e hoʻopuka hou ʻo VNTA i ka ADOC mua i pili wale i nā mea hana kūloko o Vietnam)

▍No ke aha MCM?

● Kaʻana like o ka ʻike hou loa

● Hoʻokumu pū i ka hale hoʻokolohua ʻo Quacert

No laila, lilo ʻo MCM i ʻelele hoʻokahi o kēia lab ma Mainland China, Hong Kong, Macau a me Taiwan.

● ʻO ka lawelawe ʻoihana hoʻokahi

ʻO MCM, kahi hui kū hoʻokahi kūpono, hāʻawi i ka hoʻāʻo, hōʻoia a me ka lawelawe ʻelele no nā mea kūʻai.

I ka makahiki 1800, ua kūkulu ka physicist Italia ʻo A. Volta i ka puʻu voltaic, nāna i wehe i ka hoʻomaka ʻana o nā pākaukau kūpono a wehewehe ʻia no ka manawa mua i ke koʻikoʻi o ka electrolyte i nā mea mālama uila electrochemical. Hiki ke ʻike ʻia ka electrolyte ma ke ʻano he uila uila a me ka ion-conducting layer ma ke ʻano o ka wai a paʻa paha, i hoʻokomo ʻia ma waena o nā electrodes maikaʻi ʻole. I kēia manawa, hana ʻia ka electrolyte kiʻekiʻe loa ma ka hoʻoheheʻe ʻana i ka paʻakai lithium paʻa (e laʻa me LiPF6) i loko o ka mea hoʻoheheʻe carbonate organik ʻole wai (e laʻa me EC a me DMC). E like me ke ʻano o ka cell cell form a me ka hoʻolālā ʻana, ʻo ka electrolyte ka mea maʻamau no ka 8% a 15% o ke kaumaha o ke kelepona. ʻO ka mea ʻē aʻe, ʻo kona flammability a me ka ʻoi aku ka maikaʻi o ka pae wela hana o -10°C a 60°C ke keʻakeʻa nei i ka hoʻomaikaʻi hou ʻana o ka ikehu a me ka palekana. No laila, ua manaʻo ʻia nā hoʻokumu ʻana o nā electrolyte hou i mea e hoʻomohala ai i ka hanauna hou o nā pākahi hou. Ke hana pū nei nā mea noiʻi e hoʻomohala i nā ʻōnaehana electrolyte like ʻole. No ka laʻana, ka hoʻohana ʻana i nā mea hoʻoheheʻe fluorinated e hiki ai ke hoʻokō i ka paikikala metala lithium maikaʻi, nā electrolytes paʻa organik a inorganic paha e pōmaikaʻi ai i ka ʻoihana kaʻa a me nā "bateri aupuni paʻa" (SSB). ʻO ke kumu nui inā hoʻololi ka electrolyte paʻa i ka electrolyte wai mua a me ka diaphragm, hiki ke hoʻomaikaʻi nui ʻia ka palekana, ka ikehu hoʻokahi a me ke ola o ka pākaukau. A laila, hōʻuluʻulu nui mākou i ka holomua noiʻi o nā electrolytes paʻa me nā mea like ʻole. Ua hoʻohana ʻia nā electrolytes paʻa paʻa ʻole i nā ʻenehana mālama uila electrochemical, e like me kekahi mau kiʻekiʻe-mehana rechargeable ʻo Na-S, Na-NiCl2 mau ʻāpana a me nā ʻona Li-I2 mua. . Ma hope i ka makahiki 2019, ua hōʻike ʻo Hitachi Zosen (Iapana) i kahi pahu pahu paʻa paʻa āpau o 140 mAh e hoʻohana ʻia ma ka lewa a hoʻāʻo ʻia ma ka International Space Station (ISS). Hoʻokumu ʻia kēia pākaukau me ka sulfide electrolyte a me nā mea ʻē aʻe i hōʻike ʻole ʻia, hiki ke hana ma waena o -40°C a me 100°C. I ka makahiki 2021 ke hoʻolauna nei ka hui i kahi pākaukau paʻa kiʻekiʻe o 1,000 mAh. ʻIke ʻia ʻo Hitachi Zosen i ka pono o nā ʻenekini paʻa no nā wahi paʻakikī e like me ke ākea a me nā mea hana ʻoihana e hana ana i kahi ʻano maʻamau. Hoʻolālā ka hui e pāpālua i ka nui o ka pākaukau ma 2025. Akā i kēia manawa, ʻaʻohe mea hoʻohana i nā kaʻa uila ma waho o ka papa.
