▍ Isitifiketi se-MIC saseVietnam

I-Circular 42/2016/TT-BTTTT ibalule ukuthi amabhethri afakwe kumaselula, amathebulethi kanye nezincwadi zokubhalela awavunyelwe ukuthunyelwa e-Vietnam ngaphandle uma engaphansi kwesitifiketi se-DoC kusukela ngo-Oct.1,2016. I-DoC kuyodingeka futhi ukuthi ihlinzeke lapho kufakwa Ukugunyazwa Kohlobo lwemikhiqizo yokugcina (omakhalekhukhwini, amaphilisi namathebulethi).

I-MIC ikhiphe i-Circular 04/2018/TT-BTTTT entsha ngoMeyi, 2018 ebeka ukuthi awusekho umbiko we-IEC 62133:2012 okhishwe ilabhorethri egunyazwe phesheya owamukelwa ngoJulayi 1, 2018. Ukuhlolwa kwendawo kuyadingeka ngenkathi ufaka isicelo sesitifiketi se-ADoC.

▍ Izinga Lokuhlola

I-QCVN101:2016/BTTT(bheka i-IEC 62133:2012)

▍PQIR

Uhulumeni wase-Vietnamese ukhiphe isimemezelo esisha No. 74/2018 / ND-CP ngoMeyi 15, 2018 ukuze sicacise ukuthi izinhlobo ezimbili zemikhiqizo engeniswe e-Vietnam zingaphansi kwesicelo se-PQIR (Product Quality Inspection Registration) lapho ilethwa e-Vietnam.

Ngokusekelwe kulo mthetho, i-Ministry of Information and Communication (MIC) yase-Vietnam ikhiphe idokhumenti esemthethweni ethi 2305/BTTTT-CVT ngoJulayi 1, 2018, ecacisa ukuthi imikhiqizo engaphansi kolawulo lwayo (okuhlanganisa namabhethri) kufanele ifakwe isicelo se-PQIR lapho ilethwa ngaphandle. eVietnam. I-SDoC izolethwa ukuze kuphothulwe inqubo yokugunyazwa kwentela engenayo. Idethi esemthethweni yokuqala ukusebenza kwalo mthethonqubo umhla ziyi-10 kuNcwaba, 2018. I-PQIR isetshenziswa ekungeniseni okukodwa e-Vietnam, okungukuthi, ngaso sonke isikhathi uma ongenisa impahla evela kwamanye amazwe engenisa impahla, uzofaka isicelo se-PQIR (ukuhlolwa kweqoqo) + SDoC.

Nokho, kubangenisi abaphuthuma ukuletha izimpahla ngaphandle kwe-SDOC, i-VNTA izoqinisekisa okwesikhashana i-PQIR futhi yenze kube lula ukuvunyelwa kwentela. Kodwa abathenga kwamanye amazwe kudingeka bathumele i-SDoC kwa-VNTA ukuze baqedele lonke uhlelo lokugunyazwa kwentela phakathi kwezinsuku eziyi-15 zokusebenza ngemva kokuvunyelwa kwentela. (I-VNTA ngeke isakhipha i-ADOC yangaphambilini esebenza kuphela kubakhi bendawo base-Vietnam)

▍Kungani i-MCM?

● Ukwabelana ngolwazi lwakamuva

● Umsunguli-munye welabhorethri yokuhlola ibhethri ye-Quacert

I-MCM ngaleyo ndlela iba ukuphela komenzeli wale lebhu e-Mainland China, Hong Kong, Macau naseTaiwan.

● Isevisi ye-Ejensi yokuma eyodwa

I-MCM, i-ejensi ekahle yokuma okukodwa, ihlinzeka ngokuhlolwa, izitifiketi kanye nesevisi ye-ejenti kumakhasimende.

Ukuphepha kohlelo lokugcina amandla kuyinto evamile. Njengenye yezingxenye ezibalulekile zesistimu yokugcina amandla, ukuphepha kwebhethri ye-lithium-ion kubaluleke kakhulu. Njengoba ukuhlolwa kokubaleka okushisayo kungahlola ngokuqondile ingozi yomlilo oyenzeka kusistimu yokugcina amandla, amazwe amaningi asungule izindlela zokuhlola ezihambisanayo kumazinga awo ukuze kuhlolwe ingozi yokubaleka okushisayo. Isibonelo, i-IEC 62619 ekhishwe yi-International Electrotechnical Commission (IEC) ibeka indlela yokusabalalisa yokuhlola umthelela wokubaleka okushisayo kweseli; Izinga lezwe laseShayina le-GB/T 36276 lidinga ukuhlolwa kokushisa okushisayo kweseli nokuhlolwa kokushisa okushisayo kwemojuli yebhethri; I-US Underwriters Laboratories (UL) ishicilela amazinga amabili, i-UL 1973 kanye ne-UL 9540A, womabili ahlola imiphumela yokushisa okushisayo. I-UL 9540A yakhelwe ngokukhethekile ukuhlola kusuka kumazinga amane: iseli, imojula, ikhabethe, nokusabalalisa ukushisa ezingeni lokufaka. Imiphumela yokuhlolwa kwe-thermal runnaway ayikwazi nje ukuhlola ukuphepha kukonke kwebhethri, kodwa futhi isivumela ukuthi siqonde ngokushesha ukugijima kwamaseli, futhi inikeze imingcele eqhathanisekayo yomklamo wokuphepha wamaseli anamakhemikhali afanayo. Iqembu elilandelayo lokuhlola idatha yokubaleka okushisayo elokuthi uqonde izici zokubaleka okushisayo esigabeni ngasinye nezinto ezikuseli.
Isigaba 1: Izinga lokushisa liyenyuka kancane kancane ngomthombo wangaphandle wokushisisa. Ngalesi sikhathi, izinga lokukhiqiza ukushisa kweseli ngu-0℃/min (0~ T1), iseli ngokwalo alishisi, futhi akukho ukusabela kwamakhemikhali ngaphakathi.
