▍Sitifiketi ya SIRIM

Pofuna chitetezo cha anthu ndi katundu, boma la Malaysia limakhazikitsa dongosolo la certification lazinthu ndikuyika zowunikira pazida zamagetsi, zambiri & ma multimedia ndi zida zomangira. Zogulitsa zoyendetsedwa zitha kutumizidwa ku Malaysia pokhapokha mutalandira satifiketi yotsimikizira zazinthu ndikuzilemba.

▍SIRIM QAS

SIRIM QAS, kampani yothandizirana ndi Malaysian Institute of Industry Standards, ndi gawo lokhalo losankhidwa la mabungwe olamulira dziko la Malaysia (KDPNHEP, SKMM, etc.).

Satifiketi yachiwiri ya batire imasankhidwa ndi KDPNHEP (Ministry of Domestic Trade and Consumer Affairs ya ku Malaysia) kuti ndiyo yokhayo yopereka ziphaso. Pakadali pano, opanga, ogulitsa kunja ndi amalonda atha kulembetsa ziphaso ku SIRIM QAS ndikufunsira kuyesa ndi kutsimikizira mabatire achiwiri pansi pa chiphaso chovomerezeka.

▍Sitifiketi ya SIRIM- Battery Yachiwiri

Batire lachiwiri pano liyenera kupatsidwa satifiketi mwakufuna kwake koma likhala likuvomerezedwa posachedwa. Tsiku lenileni lovomerezeka limadalira nthawi yolengezetsa yaku Malaysian. SIRIM QAS yayamba kale kuvomereza zopempha za certification.

Chitsimikizo cha batri yachiwiri: MS IEC 62133:2017 kapena IEC 62133:2012

▍Chifukwa chiyani MCM?

● Anakhazikitsa njira yabwino yosinthira luso ndi njira yosinthira zidziwitso ndi SIRIM QAS yomwe idapatsa katswiri kuti azigwira ntchito ndi mapulojekiti a MCM ndi mafunso okha ndikugawana zambiri zaposachedwa kwambiri za derali.

● SIRIM QAS imazindikira data yoyeserera ya MCM kuti zitsanzo ziyesedwe mu MCM m'malo motumiza ku Malaysia.

● Kupereka chithandizo chamtundu umodzi wotsimikizira za mabatire, ma adapter ndi mafoni aku Malaysia.

Pa kulipiritsa ndi kutulutsidwa kwa mabatire, mphamvuyo idzakhudzidwa ndi kuwonjezereka kwa mphamvu chifukwa cha kukana kwa mkati. Monga gawo lofunikira la batri, kukana kwamkati ndikofunikira kufufuza pakuwunika kuwonongeka kwa batri. Kukaniza mkati mwa batri kumakhala ndi: Ohm internal resistance (RΩ) -Kukaniza kuchokera ku ma tabo, electrolyte, separator ndi zigawo zina.Malipiro opatsirana opatsirana mkati (Rct) - Kukana kwa ma ion kudutsa ma tabo ndi electrolyte. Izi zikuyimira zovuta zamachitidwe a ma tabo. Kawirikawiri tikhoza kuonjezera conductivity kuti tichepetse kukana uku.
Polarization Resistance (Rmt) ndi kukana kwamkati komwe kumachitika chifukwa cha kusamvana kwa ma lithiamu ayoni pakati pa cathode ndi anode. Polarization Resistance idzakhala yapamwamba kwambiri ngati kulipiritsa kutentha kochepa kapena mtengo wapamwamba kwambiri. Nthawi zambiri timayesa ACIR kapena DCIR. ACIR ndiye kukana kwamkati komwe kuyezedwa mu 1k Hz AC pano. Kukana kwamkati kumeneku kumadziwikanso kuti Ohm resistance. Kuperewera kwa deta ndikuti sikungathe kuwonetsa mwachindunji ntchito ya batri. DCIR imayesedwa ndi kukakamizidwa kosalekeza mu nthawi yochepa, momwe magetsi amasinthira mosalekeza. Ngati nthawi yomweyo ndi ine, ndipo kusintha kwa magetsi mu nthawi yochepayi ndi ΔＵ, malinga ndi lamulo la OhmＲ＝ΔＵ／Ｉ Titha kupeza DCIR. DCIR sikuti imangokhala kukana kwa Ohm mkati, komanso kukana kusamutsa komanso kukana polarization.
