▍ ANATEL Homologation yog dab tsi?

ANATEL yog luv luv rau Agencia Nacional de Telecomunicacoes uas yog Brazil tsoomfwv txoj cai tswjfwm kev sib txuas lus cov khoom lag luam rau ob qho tib si yuav tsum tau lees paub thiab yeem daim ntawv pov thawj. Nws cov kev pom zoo thiab kev ua raws cai yog tib yam rau Brazil cov khoom siv hauv tsev thiab txawv teb chaws. Yog tias cov khoom muaj feem xyuam rau cov ntawv pov thawj uas yuav tsum tau ua, cov ntawv xeem thiab daim ntawv tshaj tawm yuav tsum ua raws li cov cai thiab cov cai uas tau thov los ntawm ANATEL. Daim ntawv pov thawj khoom yuav tsum tau tso cai los ntawm ANATEL ua ntej cov khoom lag luam nthuav tawm hauv kev lag luam thiab muab tso rau hauv daim ntawv thov.

▍ Leej twg yog tus lav rau ANATEL Homologation?

Lub koom haum Brazilian tsoomfwv tus qauv, lwm lub koom haum lees paub thiab cov chaw kuaj sim yog ANATEL daim ntawv pov thawj txoj cai rau kev tshuaj xyuas cov txheej txheem tsim khoom, xws li cov txheej txheem tsim khoom, kev yuav khoom, txheej txheem tsim khoom, tom qab kev pabcuam thiab lwm yam txhawm rau txheeb xyuas cov khoom siv lub cev kom ua raws. nrog Brazil tus qauv. Tus neeg tsim khoom yuav tsum muab cov ntaub ntawv thiab cov qauv rau kev sim thiab ntsuas.

▍ Vim li cas MCM?

● MCM muaj 10 xyoo kev paub dhau los thiab cov peev txheej hauv kev sim thiab ntawv pov thawj kev lag luam: cov kev pabcuam zoo, pab pawg ua haujlwm tau zoo, ceev thiab yooj yim daim ntawv pov thawj thiab cov kev daws teeb meem.

● MCM koom tes nrog ntau lub koom haum zoo hauv zos uas tau lees paub los muab ntau yam kev daws teeb meem, kev pabcuam raug thiab yooj yim rau cov neeg siv khoom.

Nyob rau hauv xyoo tas los no, cov lus ceeb toom ntawm hluav taws kub thiab txawm tias tawg los ntawm lithium-ion roj teeb muaj ntau.
Cov roj teeb lithium-ion feem ntau yog tsim los ntawm cov khoom siv tsis zoo electrode, electrolyte thiab cov khoom zoo electrode. Cov tshuaj lom neeg ua haujlwm ntawm cov khoom siv tsis zoo electrode graphite hauv lub xeev them yog me ntsis zoo li hlau lithium. SEI zaj duab xis nyob rau saum npoo yuav decompose ntawm qhov kub thiab txias, thiab lithium ions embedded nyob rau hauv lub graphite yuav hnov ​​​​mob nrog cov electrolyte thiab cov binder polyvinylidene fluoride thiab thaum kawg yuav tso tawm ntau cua sov.
Alkyl carbonate organic tov yog feem ntau siv los ua electrolytes, uas yog flammable. Qhov zoo
Cov khoom siv electrode feem ntau yog hloov pauv hlau oxide, uas muaj zog oxidizing zog hauv lub xeev them, thiab yooj yim decomposes tso pa tawm ntawm qhov kub thiab txias. Cov pa oxygen tso tawm reacts nrog cov electrolyte kom oxidize, thiab tom qab ntawd los tawm ntau heev.
Apperately, lub roj teeb lithium ion yuav tsis ruaj khov thaum cua sov nrog kub siab. Txawm li cas los xij, dab tsi
Qhov tseeb yuav tshwm sim yog tias peb khaws cov roj teeb cua sov? Ntawm no peb tau ua qhov kev sim tiag tiag rau qhov them tag nrho NCM cell nrog voltage ntawm 3.7 V thiab muaj peev xwm ntawm 106 Ah.
Txoj Kev Xeem:
1. Nyob rau hauv chav tsev kub (25 ± 2 ℃), tib lub xovtooj ntawm tes yog thawj zaug tawm mus rau qhov qis qis voltage nrog tam sim no
ntawm 1C thiab sab laug rau 15 feeb. Tom qab ntawd siv 1C tsis tu ncua tam sim no los them rau lub zog txwv sab sauv thiab hloov
kom tsis tu ncua voltage them, nres them thaum lub them tam sim no poob rau 0.05C, thiab muab tso tseg rau
15 feeb tom qab them nyiaj;
