▍Shahaadada MIC ee Vietnam

Wareegtada 42/2016/TT-BTTTT ayaa qeexaysa in baytariyada ku rakiban talefannada gacanta, tablets-ka iyo buugaagta wax lagu qoro aan loo dhoofin Vietnam haddii aan la marin shahaadada DoC tan iyo Oct.1,2016. DoC sidoo kale waxaa looga baahan doonaa inay bixiso marka la codsanayo Nooca Oggolaanshaha ee alaabta dhamaadka ah (telefoonada gacanta, tablet-yada iyo buugaagta xusuus qorka).

MIC waxay soo saartay Wareegto cusub 04/2018/TT-BTTTT bishii Maajo,2018 taas oo qeexaysa in aan mar dambe IEC 62133:2012 warbixin ay soo saartay shaybaadhka la aqoonsan yahay ee dibadda la aqbalay July 1, 2018. Imtixaanka maxalliga ahi waa lama huraan marka la codsanayo shahaadada ADoC.

▍PQIR

Dowladda Vietnam ayaa soo saartay amar cusub oo lambarkiisu yahay 74/2018 / ND-CP May 15, 2018 si ay u qeexdo in laba nooc oo badeecooyin ah oo la keeno Vietnam ay ku xiran yihiin codsiga PQIR (Diiwaangelinta Tayada Alaabta) marka loo soo dhoofiyo Vietnam.

Iyada oo ku saleysan sharcigan, Wasaaradda Warfaafinta iyo Isgaarsiinta (MIC) ee Vietnam waxay soo saartay dukumeenti rasmi ah 2305/BTTTT-CVT Julaay 1, 2018, taasoo qeexaysa in alaabada ay maamusho (oo ay ku jiraan baytariyada) waa in lagu codsadaa PQIR marka la soo dejinayo galay Vietnam. SdoC waa in la soo gudbiyaa si loo dhamaystiro nidaamka fasaxida kastamka. Taariikhda rasmiga ah ee uu dhaqan gelayo xeerkani waa Agoosto 10, 2018. PQIR waxay khusaysaa hal mar oo loo soo dhoofiyo Vietnam, taas oo ah, mar kasta oo soodejiye alaab soo dejiyo, waa inuu dalbadaa PQIR (baaritaan dufcad) + SdoC.

Si kastaba ha ahaatee, kuwa soo dajiyaasha ah ee degdega u ah inay alaab la'aan SDOC soo dejiyaan, VNTA waxay si ku meel gaar ah u xaqiijin doontaa PQIR waxayna fududayn doontaa fasaxa kastamka. Laakin soo dejiyeyaashu waxay u baahan yihiin inay u soo gudbiyaan SdoC VNTA si ay u dhamaystiraan dhammaan nidaamka banaynta kastamka 15 maalmood oo shaqo gudahooda kadib fasaxa kastamka. (VNTA mar dambe ma soo saari doonto ADOC-gii hore kaas oo kaliya lagu dabaqi karo Warshadaha Maxalliga ah ee Vietnam)

▍Waa maxay sababta MCM?

● Wadaaga xogtii ugu dambaysay

● Aasaasaha shaybaadhka tijaabada batteriga Quacert

MCM sidaas darteed wuxuu noqonayaa wakiilka kaliya ee shaybaadhkan ee Mainland China, Hong Kong, Macau iyo Taiwan.

● Adeegga Wakaalada Hal-Stop

MCM, oo ah wakaalad hal-joojin ah oo ku habboon, waxay siisa imtixaan, shahaado iyo adeeg wakiil macaamiisha.

Inta lagu jiro dallacaadda iyo bixinta baytariyada, awoodda waxaa saameyn ku yeelan doona kororka kororka ee ay keento iska caabbinta gudaha. Sida halbeegga muhiimka ah ee batteriga, iska caabbinta guduhu waxay u qalantaa cilmi-baadhis lagu falanqeeyo xaalufka batteriga. Iska caabbinta gudaha ee batteriga waxaa ku jira: Ohm iska caabbinta gudaha (RΩ) - Caabbinta ka timaadda tabs, electrolyte, separator iyo qaybaha kale. Tani waxay ka dhigan tahay dhibka falcelinta tabs. Caadi ahaan waxaan kordhin karnaa korantada si loo yareeyo iska caabintan. Iska caabinta Polarization (Rmt) waa iska caabbinta gudaha ee ay keento cufnaanta aan sinnayn ee ion lithium inta u dhaxaysa cathode iyo anode. Iska caabbinta dabaysha waxay noqon doontaa mid sareeysa xaaladaha sida ku dallaca heerkulka hoose ama lacag la qiimeeyay sare. Sida caadiga ah waxaan cabbirnaa ACIR ama DCIR. ACIR waa iska caabbinta gudaha ee lagu qiyaasay 1k Hz AC hadda. Iska caabintan gudaha waxaa sidoo kale loo yaqaan caabbinta Ohm. Yaraanta xogta ayaa ah in aysan si toos ah u muujin karin waxqabadka batteriga. DCIR waxaa lagu qiyaasaa xoog joogto ah oo joogto ah muddo gaaban gudaheed, kaas oo korontadu si joogto ah isu beddesho. Haddii wakhtiga degdega ahi uu yahay I, iyo isbeddelka tamarta wakhtigaas gaaban waa ΔＵ, sida uu qabo sharciga Ohm Ｒ＝Δ／Ｉ Waxaan heli karnaa DCIR. DCIR ma aha oo kaliya iska caabinta gudaha Ohm, laakiin sidoo kale waxay dallacaa iska caabinta wareejinta iyo iska caabinta polarization.
Had iyo jeer way ku adag tahay cilmi-baarista DCIR ee baytariga lithium-ion. Inta badan waa sababta oo ah iska caabbinta gudaha ee baytariga lithium-ion waa mid aad u yar, badiyaa xoogaa mΩ ah. Dhanka kale sida qayb firfircoon, way adagtahay in la cabbiro iska caabbinta gudaha si toos ah. Ka sokow, iska caabinta gudaha waxaa saameeya heerka deegaanka, sida heerkulka iyo heerka kharashka. Hoos waxaa ah jaangooyooyin sheegay sida loo tijaabiyo DCIR.
