▍ Isitifiketi se-SIRIM
Ukuze kuvikeleke umuntu nempahla, uhulumeni wase-Malaysia usungula uhlelo lokunikeza isitifiketi somkhiqizo futhi uqapha izinto zikagesi zikagesi, ulwazi & multimedia nezinto zokwakha. Imikhiqizo elawulwayo ingathunyelwa e-Malaysia kuphela ngemva kokuthola isitifiketi sokuqinisekiswa komkhiqizo nokulebula.
▍SIRIM QAS
I-SIRIM QAS, inkampani ephethwe ngokugcwele ye-Malaysian Institute of Industry Standards, iyona kuphela iyunithi yesitifiketi eqokiwe yama-ejensi kazwelonke alawulayo e-Malaysian (KDPNHEP, SKMM, njll.).
Isitifiketi sebhethri sesibili sikhethwe i-KDPNHEP (uMnyango Wezohwebo Zasekhaya kanye Nezindaba Zabathengi) waseMalaysia njengowukuphela kwesiphathimandla sokunikeza izitifiketi. Okwamanje, abakhiqizi, abangenisi nabahwebi bangafaka isicelo sokuthola isitifiketi ku-SIRIM QAS futhi bafake isicelo sokuhlolwa nokuqinisekiswa kwamabhethri esibili ngaphansi kwemodi yesitifiketi enelayisensi.
▍ Isitifiketi se-SIRIM- Ibhethri Lesibili
Ibhethri lesibili okwamanje lingaphansi kwesitifiketi sokuzithandela kodwa lizoba kububanzi besitifiketi esiyisibopho maduze. Usuku oluqondile oluyisibopho lungaphansi kwesikhathi esisemthethweni sesimemezelo sase-Malaysian. I-SIRIM QAS isivele isiqalile ukwamukela izicelo zesitifiketi.
Izinga lesitifiketi sebhethri lesibili : MS IEC 62133:2017 noma IEC 62133:2012
▍Kungani i-MCM?
● Isungule isiteshi esihle sokushintshisana sobuchwepheshe nolwazi lokushintshisana ne-SIRIM QAS eyabela uchwepheshe ukuthi aphathe amaphrojekthi we-MCM nemibuzo kuphela kanye nokwabelana ngolwazi lwakamuva olunembile lwale ndawo.
● I-SIRIM QAS ibona idatha yokuhlola ye-MCM ukuze amasampuli akwazi ukuhlolwa nge-MCM esikhundleni sokulethwa e-Malaysia.
● Ukuhlinzeka ngesevisi yokuma okukodwa kokugunyazwa kwe-Malaysian kwamabhethri, ama-adaptha namaselula.
Ngesikhathi sokushaja nokukhipha amabhethri, amandla azothonywa ukugcwala ngokweqile okubangelwa ukumelana kwangaphakathi. Njengepharamitha ebalulekile yebhethri, ukumelana kwangaphakathi kuwufanele ucwaningo ukuze kuhlaziywe ukuwohloka kwebhethri. Ukumelana kwangaphakathi kwebhethri kuqukethe:I-Ohm ukumelana kwangaphakathi (RΩ) -Ukumelana namathebhu, i-electrolyte, isihlukanisi nezinye izakhi.Izindleko zokudlulisa ukumelana kwangaphakathi (Rct) - Ukumelana kwamathebhu adlula ama-ion kanye ne-electrolyte. Lokhu kumelela ubunzima bokusabela kwamathebhu. Ngokujwayelekile singakwazi ukukhulisa i-conductivity ukunciphisa lokhu kumelana.
I-Polarization Resistance (Rmt) ukumelana kwangaphakathi okubangelwa ukuminyana kokungalingani kwe-lithium ion phakathi kwe-cathode ne-anode. I-Polarization Resistance izoba phezulu ezimeni ezifana nokushajwa kwezinga lokushisa eliphansi noma inkokhiso enesilinganiso esiphezulu.Ngokujwayelekile sikala i-ACIR noma i-DCIR. I-ACIR ukumelana kwangaphakathi kukalwa ngo-1k Hz AC wamanje. Lokhu kumelana kwangaphakathi kwaziwa nangokuthi ukumelana kwe-Ohm. Ukushoda kwedatha ukuthi ayikwazi ukukhombisa ngqo ukusebenza kwebhethri. I-DCIR ikalwa ngokuphoqwa okungaguquki kwamandla ngesikhathi esifushane, lapho i-voltage ishintsha njalo. Uma i-current esheshayo ithi I, futhi ukushintsha kwamandla kagesi kuleso sikhathi esifushane kungu-ΔＵ, ngokomthetho we-OhmＲ＝ΔＵ／Ｉ Singathola i-DCIR. I-DCIR ayikona nje ukumelana ne-Ohm yangaphakathi, kodwa futhi ukumelana nokushaja kokudlulisa kanye nokumelana ne-polarization.
