▍ Vim li cas MCM?
● Kev txhawb nqa muag los ntawm kev tsim nyog thiab thev naus laus zis:Raws li lub chaw kuaj neeg ua pov thawj ntawm TUVRH thiab ITS hauv North American Certification, MCM muaj peev xwm ua tau txhua yam kev sim thiab muab kev pabcuam zoo dua los ntawm kev sib pauv tshuab ntsej muag.
● Kev txhawb nqa nyuaj los ntawm kev siv tshuab:MCM tau nruab nrog tag nrho cov khoom siv ntsuas rau cov roj teeb ntawm qhov loj-loj, me me thiab cov haujlwm ua tau zoo (xws li lub tsheb fais fab, lub zog cia, thiab cov khoom siv hluav taws xob digital), muaj peev xwm muab tag nrho cov roj teeb kuaj thiab ntawv pov thawj cov kev pabcuam hauv North America, npog cov qauv. UL2580, UL1973, UL2271, UL1642, UL2054 thiab lwm yam.
CTIA sawv cev rau Cellular Telecommunications thiab Internet Association, lub koom haum ntiag tug tsis muaj txiaj ntsig hauv Tebchaws Meskas. CTIA muab kev tsis ncaj ncees, ywj siab thiab nruab nrab ntawm cov khoom lag luam ntsuas thiab ntawv pov thawj rau kev lag luam wireless. Raws li daim ntawv pov thawj no, tag nrho cov neeg siv khoom siv wireless yuav tsum dhau qhov kev sib tw ua raws thiab ua tau raws li qhov yuav tsum tau muaj ntawm cov qauv tsim ua ntej lawv tuaj yeem muag hauv North American kev sib txuas lus lag luam.Cov ntawv pov thawj yuav tsum tau ua raws li IEEE1725 yog siv tau rau ib leeg-cell thiab Multi-cell roj teeb nyob rau hauv parallel.Certification Requirement for Battery system Compliance to IEEE1625 is available to multi-cell batteries with core connection in series or parallel.Notice: ob lub xov tooj ntawm tes roj teeb thiab lub computer roj teeb yuav tsum xaiv cov ntawv pov thawj raws li cov saum toj no, hloov ntawm IEEE1725 rau xov tooj ntawm tes thiab IEEE1625 rau computer.MCM yog CTIA-accredited laboratory.MCM muaj peev xwm muab tag nrho cov kev pab cuam xws li xa daim ntawv thov, kuaj, soj ntsuam thiab uploading cov ntaub ntawv, thiab lwm yam.
