Icyemezo cya Vietnam MIC

Kuzenguruka 42/2016 / TT-BTTTT yavugaga ko bateri zashyizwe muri terefone zigendanwa, tableti n'amakaye bitemewe koherezwa muri Vietnam keretse iyo zihawe icyemezo cya DoC kuva Ukwakira.2016. DoC izasabwa kandi gutanga mugihe usaba Ubwoko bwo Kwemeza ibicuruzwa byanyuma (terefone igendanwa, tableti n'amakaye).

MIC yasohoye uruziga rushya 04/2018 / TT-BTTTT muri Gicurasi, 2018 iteganya ko nta raporo ya IEC 62133: 2012 yatanzwe na laboratoire yemewe mu mahanga itemewe muri Nyakanga, 2018. Ikizamini cyaho ni ngombwa mu gihe usaba icyemezo cya ADoC.

Ikizamini gisanzwe

QCVN101 ： 2016 / BTTTT （reba IEC 62133 ： 2012)

▍PQIR

Ku ya 15 Gicurasi 2018, guverinoma ya Viyetinamu yasohoye iteka rishya No 74/2018 / ND-CP kugira ngo rivuga ko ubwoko bubiri bw’ibicuruzwa byatumijwe muri Vietnam bisabwa na PQIR (Kwiyandikisha ku bicuruzwa byujuje ubuziranenge) iyo byinjijwe muri Vietnam.

Hashingiwe kuri iri tegeko, Minisiteri y’itangazamakuru n’itumanaho (MIC) yo muri Vietnam yasohoye inyandiko yemewe 2305 / BTTTT-CVT ku ya 1 Nyakanga 2018, ivuga ko ibicuruzwa bigenzurwa (harimo na bateri) bigomba gukoreshwa kuri PQIR igihe byatumijwe mu mahanga. muri Vietnam. SDoC igomba gutangwa kugirango irangize inzira yo gukuraho gasutamo. Itariki yemewe yo gukurikizwa muri aya mabwiriza ni ku ya 10 Kanama 2018. PQIR ikoreshwa ku bicuruzwa bimwe bitumizwa muri Vietnam, ni ukuvuga ko igihe cyose uwatumije mu mahanga ibicuruzwa bitumiza mu mahanga, azasaba PQIR (ubugenzuzi bw'icyiciro) + SDoC.

Ariko, kubatumiza ibicuruzwa byihutirwa gutumiza ibicuruzwa bidafite SDOC, VNTA izagenzura by'agateganyo PQIR kandi byorohereze gasutamo. Ariko abatumiza mu mahanga bakeneye kohereza SDoC kuri VNTA kugirango barangize inzira zose zo gukuraho gasutamo mugihe cyiminsi 15 yakazi nyuma yo gutangirwa gasutamo. (VNTA ntizongera gutanga ADOC ibanza ikoreshwa gusa muri Vietnam ikora inganda)

Kuki MCM?

Gusangira amakuru agezweho

● Twashinze laboratoire yo gupima batiri ya Quacert

MCM rero iba umukozi wenyine wiyi laboratoire mu Bushinwa, Hong Kong, Macau na Tayiwani.

Service Serivisi imwe yo guhagarika serivisi

MCM, ikigo cyiza cyo guhagarika icyarimwe, gitanga ibizamini, ibyemezo na serivisi kubakiriya.

Mu 1800, umuhanga mu bya fiziki w’umutaliyani A. Volta yubatse ikirundo cya voltaque, cyafunguye intangiriro ya bateri zifatika anasobanura ku nshuro ya mbere akamaro ka electrolyte mu bikoresho bibika ingufu z’amashanyarazi. Electrolyte irashobora kubonwa nkigikoresho cya elegitoroniki kandi ikora ion mu buryo bwamazi cyangwa ikomeye, byinjijwe hagati ya electrode mbi kandi nziza. Kugeza ubu, electrolyte yateye imbere ikorwa no gushonga umunyu wa lithium ukomeye (urugero LiPF6) mumashanyarazi ya karubone idafite amazi (urugero EC na DMC). Nkurikije imiterere rusange yimiterere nigishushanyo, electrolyte mubusanzwe ifite 8% kugeza 15% byuburemere bwakagari. Ikirenzeho, umuriro wacyo hamwe nubushyuhe bwo gukora bwa dogere -10 ° C kugeza kuri 60 ° C bibangamira cyane kurushaho kunoza ingufu za batiri n’umutekano. Kubwibyo, guhanga udushya twa electrolyte bifatwa nkibyingenzi byingenzi mugutezimbere igisekuru kizaza cya bateri nshya. Abashakashatsi nabo barimo gukora kugirango bateze imbere sisitemu zitandukanye za electrolyte. Kurugero, ikoreshwa ryumuti wa fluor ushobora kugera kumagare meza ya lithium yicyuma cyamagare, organic cyangwa organic organique ikomeye ya electrolytite ifasha inganda zimodoka na "bateri zikomeye za leta" (SSB). Impamvu nyamukuru nuko niba electrolyte ikomeye isimbuye electrolyte yumwimerere na diaphragm, umutekano, ubwinshi bwingufu nubuzima bwa bateri birashobora kunozwa kuburyo bugaragara. Ibikurikira, turagaragaza cyane cyane muri make iterambere ryubushakashatsi bwa electrolytite ikomeye hamwe nibikoresho bitandukanye.Ibikoresho bya elegitoroniki ikomeye ya elegitoronike yakoreshejwe mubikoresho byo kubika ingufu za electrochemicique yubucuruzi, nka bateri zimwe na zimwe zishyushya ubushyuhe bwo hejuru zishobora kwishyurwa Na-S, Na-NiCl2 na batiri yambere Li-I2. . Muri 2019, Hitachi Zosen (Ubuyapani) yerekanye bateri yuzuye ya paki ya paki ya mAh 140 kugirango ikoreshwe mu kirere kandi igeragezwa kuri sitasiyo mpuzamahanga (ISS). Iyi bateri igizwe na sulfide electrolyte nibindi bikoresho bya batiri bitamenyekanye, ibasha gukora hagati ya -40 ° C na 100 ° C. Muri 2021 isosiyete izana bateri ifite ubushobozi bukomeye bwa mAh 1.000. Hitachi Zosen abona ko hakenewe bateri zikomeye kubidukikije bikaze nkumwanya nibikoresho byinganda bikorera mubidukikije bisanzwe. Isosiyete irateganya gukuba kabiri ingufu za batiri mu 2025. Ariko kugeza ubu, nta bicuruzwa bikomoka kuri batiri-byose bishobora gukoreshwa mu binyabiziga by’amashanyarazi.
