Ngqo ngoku,

▍Isiqinisekiso se-MIC saseVietnam

ISetyhula 42/2016/TT-BTTTT ichaze ukuba iibhetri ezifakwe kwiifowuni eziphathwayo, iitafile kunye neencwadana zokubhalela azivumelekanga ukuba zithunyelwe eVietnam ngaphandle kokuba ziphantsi kwe-DoC certifctaion ukususela ngo-Oct.1,2016. I-DoC iya kuphinda ifuneke ukuba ibonelele xa ifaka isicelo sokuVunywa koHlobo lweemveliso zokuphela konyaka (iimfonomfono eziphathwayo, iitafile kunye neencwadana).

I-MIC ikhuphe iSetyhula entsha ye-04/2018/TT-BTTT ngoMeyi, i-2018 echaza ukuba akukho ngxelo ye-IEC 62133:2012 ekhutshwe yilabhoratri evunyiweyo yaphesheya yamkelwa ngoJulayi 1, 2018. Uvavanyo lwendawo luyimfuneko ngelixa ufaka isicelo sesatifikethi se-ADoC.

▍PQIR

Urhulumente waseVietnam ukhuphe umyalelo omtsha onguNombolo 74/2018 / ND-CP ngoMeyi 15, 2018 ukuba uchaze ukuba iintlobo ezimbini zeemveliso ezingeniswe eVietnam zixhomekeke kwi-PQIR (Ukubhaliswa kokuHlolwa koMgangatho weMveliso) xa zithunyelwa eVietnam.

Ngokusekelwe kulo mthetho, i-Ofisi yoLwazi kunye noNxibelelwano (MIC) yaseVietnam ikhuphe uxwebhu olusemthethweni lwe-2305/BTTTT-CVT ngoJulayi 1, 2018, oluchaza ukuba iimveliso eziphantsi kolawulo lwayo (kubandakanywa neebhetri) kufuneka zifakwe kwi-PQIR xa zithunyelwa ngaphandle. ukuya eVietnam. I-SDoC iya kungeniswa ukuze igqibezele inkqubo yokukhutshwa kwempahla ekhoyo. Umhla osemthethweni wokungena ekusebenzeni kwalo mmiselo ngo-Agasti 10, 2018. I-PQIR isetyenziswa ekungeniseni enye eVietnam, oko kukuthi, rhoqo xa umthengisi engenisa iimpahla, uya kufaka isicelo se-PQIR (ukuhlolwa kwebhetshi) + SDoC.

Nangona kunjalo, kubarhwebi abangxamisekileyo ukuba bangenise iimpahla ngaphandle kwe-SDOC, i-VNTA iya kuqinisekisa okwethutyana i-PQIR kwaye iququzelele ukukhutshwa kwempahla. Kodwa abathumeli bangaphandle kufuneka bangenise i-SDoC kwi-VNTA ukuze igqibezele inkqubo yokukhutshwa kwempahla ngaphandle kwempahla ngaphakathi kwe-15 leentsuku zokusebenza emva kokukhutshwa kwempahla ephumayo. (I-VNTA ayisayi kuphinda ikhuphe i-ADOC yangaphambili esebenza kuphela kwi-Vietnam Local Manufacturers)

▍Kutheni i-MCM?

● Umxhasi woLwazi lwamva nje

● Umseki wegumbi lovavanyo lwebhetri yeQuacert

I-MCM ngoko iba yeyona arhente ikuphela kwayo yale lebhu e-Mainland China, eHong Kong, eMacau naseTaiwan.

● Inkonzo ye-Arhente yokuma enye

I-MCM, i-arhente efanelekileyo yokumisa enye, ibonelela ngovavanyo, isatifikethi kunye nenkonzo ye-arhente kubathengi.

Ngexesha lokutshaja kunye nokukhutshwa kweebhetri, umthamo uya kuthotyelwa ngokugqithiswa kwe-overvoltage okubangelwa ukuchasana kwangaphakathi. Njengeparameter ebalulekileyo yebhetri, ukuchasana kwangaphakathi kulufanele uphando lokuhlalutya ukuhla kwebhetri. Ukuchasana kwangaphakathi kwebhetri kuqulethe: I-Ohm ukuchasana kwangaphakathi (RΩ) -Ukuxhathisa kwiithebhu, i-electrolyte, i-separator kunye namanye amacandelo.Intlawulo yokuhanjiswa kwe-internal resistance (Rct) - Ukuxhatshazwa kwee-ion ezidlulayo iithebhu kunye ne-electrolyte. Oku kubonisa ubunzima bokusabela kweethebhu. Ngokuqhelekileyo sinokunyusa i-conductivity ukunciphisa oku kuxhathisa.I-Polarization Resistance (Rmt) ukuchasana kwangaphakathi okubangelwa ubuninzi bokungalingani kwe-lithium ion phakathi kwe-cathode kunye ne-anode. I-Polarization Resistance iya kuba phezulu kwiimeko ezifana nokutshaja kwiqondo lokushisa eliphantsi okanye intlawulo ephezulu. Ngokuqhelekileyo silinganisa i-ACIR okanye i-DCIR. I-ACIR yinkcaso yangaphakathi elinganiswa kwi-1k Hz AC yangoku. Oku kuxhathisa kwangaphakathi kwaziwa ngokuba yi-Ohm resistance. Ukunqongophala kwedatha kukuba ayikwazi ukubonisa ngokuthe ngqo ukusebenza kwebhetri. I-DCIR ilinganiswa ngokunyanzeliswa kwangoku ngokuqhubekayo ngexesha elifutshane, apho i-voltage iguquka ngokuqhubekayo. Ukuba i-current current i-I, kwaye utshintsho lwe-voltage ngelo xesha elifutshane ngu-ΔＵ, ngokomthetho we-Ohm Ｒ＝ΔＵ／Ｉ Singayifumana i-DCIR. I-DCIR ayisiyiyo kuphela i-Ohm yokuchasana kwangaphakathi, kodwa iphinda ihlawule ukuchasana nokugqithiswa kunye nokuxhathisa i-polarization.
Kuhlala kunzima kuphando lwe-DCIR yebhetri ye-lithium-ion. Ikakhulu kungenxa yokuba ukuxhathisa kwangaphakathi kwebhetri ye-lithium-ion kuncinci kakhulu, kuqhelekile ukuba yimΩ. Okwangoku njengecandelo elisebenzayo, kunzima ukulinganisa ukuchasana kwangaphakathi ngokuthe ngqo. Ngaphandle koko, ukuxhathisa kwangaphakathi kuphenjelelwa yimeko yemo engqongileyo, njengobushushu kunye nobume beentlawulo. Apha ngezantsi kukho imigangatho ekhankanyiweyo malunga nendlela yokuvavanya i-DCIR.
