▍Vietnam MIC Certification

Circular 42/2016/TT-BTTTT yakataura kuti mabhatiri akaiswa munharembozha, mahwendefa nemabhuku ekunyorera haabvumidzwe kuendeswa kunze kwenyika kuVietnam kunze kwekunge aiswa pasi peDoC certifctaion kubvira Oct.1,2016. DoC inozodikanwawo kupa kana uchinyorera Type Mvumo yezvigadzirwa zvekupedzisira (nharembozha, mahwendefa nemabhuku ekunyorera).

MIC yakaburitsa Circular 04/2018/TT-BTTT itsva muna Chivabvu, 2018 iyo inoti hapasisina IEC 62133:2012 mushumo wakabudiswa nerabhoritari yemhiri kwemakungwa yakatenderwa inogamuchirwa muna Chikunguru 1, 2018. Kuongororwa kwenzvimbo kunodiwa paunenge uchinyorera chitupa cheADoC.

▍ Testing Standard

QCVN101: 2016/BTTT(inongedza kuIEC 62133:2012)

▍PQIR

Hurumende yeVietnam yakapa chirevo chitsva No. 74/2018 / ND-CP musi wa15 Chivabvu, 2018 kuti vataure kuti marudzi maviri ezvigadzirwa zvinotengeswa kunze kwenyika kuVietnam zviri pasi pePQIR (Product Quality Inspection Registration) application painounzwa kuVietnam.

Zvichienderana nemutemo uyu, Ministry of Information and Communication (MIC) yekuVietnam yakapa gwaro repamutemo 2305/BTTTT-CVT musi waChikunguru 1, 2018, richitaura kuti zvigadzirwa zviri pasi payo (kusanganisira mabhatiri) zvinofanirwa kuiswa kuPQIR kana zvichitengeswa kunze kwenyika. kuVietnam. SDoC ichaendeswa kuti ipedze hurongwa hwekubvisa tsika. Zuva repamutemo rekupinda musimba remutemo uyu ndiAugust 10, 2018. PQIR inoshandiswa kune imwe chete inotengeswa kuVietnam, ndiko kuti, nguva dzose apo mutengesi anopinza zvinhu kunze kwenyika, achanyorera PQIR (batch inspection) + SDoC.

Nekudaro, kune vanotenga kunze kwenyika vari kukurumidza kupinza zvinhu kunze kweSDOC, VNTA ichaongorora PQIR kwenguva pfupi uye kufambisa kubvumidzwa kwetsika. Asi vanotenga kunze kwenyika vanofanirwa kuendesa SDoC kuVNTA kuti vapedze hurongwa hwese hwekubvisa tsika mukati memazuva gumi nemashanu ekushanda mushure mekubvumidzwa kwetsika. (VNTA haichabudisi yekare ADOC inongoshanda kuVietnam Local Manufacturers)

▍ Neiko MCM?

MCM, yakanakira imwe-stop agency, inopa kuyedzwa, chitupa uye sevhisi sevhisi kune vatengi.

Muna 1800, nyanzvi yefizikisi yeItaly A. Volta yakavaka murwi wevoltaic, iyo yakazarura kutanga kwemabhatiri anoshanda uye yakatsanangura kwekutanga kukosha kwe electrolyte mumagetsi emagetsi ekuchengetedza magetsi. Iyo electrolyte inogona kuonekwa seyemagetsi insulating uye ion-conducting layer muchimiro chemvura kana yakasimba, inoiswa pakati pemagetsi asina kunaka uye akanaka. Parizvino, electrolyte yepamusorosoro inogadzirwa nekunyungudutsa yakasimba lithium munyu (eg LiPF6) mune isiri-aqueous organic carbonate solvent (eg EC uye DMC). Sekureva kwesero rese fomu uye dhizaini, iyo electrolyte inowanzoita 8% kusvika 15% yehuremu hwesero. Pamusoro pezvo, kupisa kwayo uye tembiricha yakakwana yekushanda kubva -10 ° C kusvika 60 ° C inotadzisa zvakanyanya kuvandudzwa kwesimba rebhatiri uye kuchengeteka. Naizvozvo, magadzirirwo matsva emagetsi emagetsi anoonekwa seanogonesa kugadzirwa kwechizvarwa chinotevera chemabhatiri matsva.Vaongorori vari kushandawo kugadzira masisitimu e electrolyte akasiyana. Semuyenzaniso, kushandiswa kwe fluorinated solvents iyo inogona kuita inobudirira lithium metal cycling, organic or inorganic solid electrolytes iyo inobatsira kumotokari yemotokari uye "solid state batteries" (SSB). Chikonzero chikuru ndechekuti kana iyo yakasimba electrolyte ikatsiva yekutanga mvura electrolyte uye diaphragm, chengetedzo, simba rimwechete uye hupenyu hwebhatiri hunogona kuvandudzwa zvakanyanya. Tevere, isu tinonyanya kupfupisa kufambira mberi kwekutsvagisa kweakasimba maelectrolyte ane akasiyana zvinhu.Inorganic solid solid electrolytes yakashandiswa mukutengesa magetsi emagetsi ekuchengetedza magetsi, senge mamwe mabhatiri akakwira-tembiricha anogona kugadzirwazve Na-S, Na-NiCl2 mabhatiri uye ekutanga Li-I2 mabhatiri. . Kudzoka muna 2019, Hitachi Zosen (Japan) yakaratidza bhatiri rehomwe-yakasimba ye140 mAh kuti ishandiswe muchadenga uye kuedzwa paInternational Space Station (ISS). Bhatiri iri rinoumbwa ne sulfide electrolyte nezvimwe zvinhu zvebhatiri zvisina kutaurwa, zvinokwanisa kushanda pakati -40°C ne100°C. Muna 2021 kambani iri kuunza bhatiri repamusoro rakasimba re1,000 mAh. Hitachi Zosen anoona kudiwa kwemabhatiri akasimba enzvimbo dzakaomarara senge nzvimbo uye zvigadzirwa zvemaindasitiri zvinoshanda munzvimbo dzakajairwa. Iyo kambani inoronga kuwedzera kaviri bhatiri simba ne 2025. Asi kusvika ikozvino, hapana kunze-kwe-sherufu yose-yakasimba-state bhatiri chigadzirwa chinogona kushandiswa mumagetsi emagetsi.
