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.

Mugihe cyo kwishyuza no gusohora bateri, ubushobozi buzaterwa numuvuduko ukabije uterwa no kurwanya imbere. Nibintu byingenzi bya bateri, kurwanya imbere birakwiye ubushakashatsi bwo gusesengura iyangirika rya batiri. Kurwanya imbere kwa bateri birimo: Ohm imbere imbere (RΩ) - Kurwanya kuva kuri tabs, electrolyte, gutandukanya nibindi bice. Ibi byerekana ingorane za tabs reaction. Mubisanzwe dushobora kongera ubushobozi bwo kugabanya iyi myigaragambyo. Kurwanya polarisiyasi (Rmt) ni ukurwanya imbere guterwa n'ubucucike butaringaniye bwa ioni ya lithium hagati ya cathode na anode. Polarisation Kurwanya bizaba byinshi mubihe nko kwishyuza mubushyuhe buke cyangwa kwishyurwa hejuru.Ubusanzwe dupima ACIR cyangwa DCIR. ACIR ni ukurwanya imbere gupimwa muri 1k Hz AC. Uku kurwanya imbere bizwi kandi nka Ohm resistance. Ibura ryamakuru nuko ridashobora kwerekana neza imikorere ya bateri. DCIR ipimwa ningufu zihoraho mugihe gito, aho voltage ikomeza guhinduka. Niba akanya ako kanya ari I, kandi ihinduka rya voltage muri kiriya gihe gito ni ΔＵ, ukurikije amategeko ya Ohm Ｒ ＝ ΔＵ ／ Ｉ Turashobora kubona DCIR. DCIR ntabwo ireba Ohm gusa imbere, ariko kandi irwanya kwimurwa no kurwanya polarisiyasi.
Burigihe biragoye kubushakashatsi bwa DCIR ya batiri ya lithium-ion. Biterwa ahanini nuko imbere yimbere ya bateri ya lithium-ion ari nto cyane, mubisanzwe mΩ. Hagati aho, nkibigize ibikorwa, biragoye gupima imbere imbere. Byongeye kandi, kurwanya imbere byatewe nuburyo ibidukikije, nkubushyuhe hamwe nuburyo bwo kwishyuza. Hano haribipimo byavuzwe kubyerekeranye no gupima DCIR.
Ibipimo mpuzamahanga:
