▍Isiqinisekiso se-SIRIM
Ngokhuseleko lomntu kunye nepropathi, urhulumente waseMalaysia useka iskim soqinisekiso lwemveliso kwaye ubeka iliso kwizixhobo zombane, ulwazi & nemultimedia kunye nemathiriyeli yokwakha. Iimveliso ezilawulwayo zinokuthunyelwa eMalaysia kuphela emva kokufumana isatifikethi semveliso kunye nokuleyibhile.
▍SIRIM QAS
I-SIRIM QAS, icandelo eliphantsi kweMalaysian Institute of Industry Standards, kuphela kweyunithi echongiweyo yesatifikethi yee-arhente zolawulo zelizwe laseMalaysia (KDPNHEP, SKMM, njl.).
Isatifikethi sebhetri yesibini sichongwe yi-KDPNHEP (uMphathiswa waseMalaysia woRhwebo lwaseKhaya kunye neMicimbi yabaThengi) njengoyena gunyaziwe woqinisekiso. Okwangoku, abavelisi, abarhwebi kunye nabarhwebi banokufaka isicelo sesiqinisekiso kwi-SIRIM QAS kwaye bafake isicelo sokuvavanywa kunye nokuqinisekiswa kweebhetri zesibini phantsi kwemo yesiqinisekiso selayisensi.
▍Isatifikethi SIRIM- Ibhetri yesibini
Ibhetri yesibini okwangoku iphantsi kwesiqinisekiso sokuzithandela kodwa izakuba kuluhlu lwesiqinisekiso esisinyanzelo kungekudala. Olona suku lunyanzelekileyo luxhomekeke kwixesha elisemthethweni le-Malaysian isaziso. I-SIRIM QAS sele iqalisile ukwamkela izicelo zesiqinisekiso.
Umgangatho wesiqinisekiso sebhetri yesibini : MS IEC 62133:2017 okanye IEC 62133:2012
▍Kutheni i-MCM?
● Kusekwe utshintshiselwano olululo lobugcisa kunye nejelo lokutshintshiselana ngolwazi kunye ne-SIRIM QAS eyabela ingcali ukuba ijongane neeprojekthi ze-MCM kunye nemibuzo kuphela kunye nokwabelana ngolwazi lwamva nje oluchanekileyo lwale ndawo.
● I-SIRIM QAS ibona idatha yovavanyo lwe-MCM ukuze iisampuli zivavanywe kwi-MCM endaweni yokuba zisiwe eMalaysia.
● Ukubonelela ngenkonzo yokuma enye kwisiqinisekiso saseMalaysia seebhetri, iiadaptha kunye neeselfowuni.
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 le nkcaso.
I-Polarization Resistance (Rmt) kukuchasana 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.
