▍Yintoni i-CTIA CERTIFICATION?

I-CTIA, isishunqulelo se-Cellular Telecommunications and Internet Association, ngumbutho woluntu ongenzi nzuzo owasekwa ngo-1984 ngenjongo yokuqinisekisa inzuzo yabasebenzi, abavelisi kunye nabasebenzisi.I-CTIA ibandakanya bonke abasebenzi base-US kunye nabavelisi abavela kwiinkonzo zikanomathotholo eziphathwayo, kunye nakwiinkonzo zedatha ezingenazingcingo kunye neemveliso.Ixhaswa yiFCC (iKomishoni yoNxibelelwano lwe-Federal) kunye neCongress, i-CTIA yenza inxalenye enkulu yemisebenzi kunye nemisebenzi eyayisetyenziselwa ukuqhutywa ngurhulumente.Ngo-1991, i-CTIA yenze inkqubo yovavanyo lwemveliso engakhethi cala, ezimeleyo nebekwe kwindawo esembindini kunye nenkqubo yoqinisekiso yoshishino olungenazingcingo.Ngaphantsi kwenkqubo, zonke iimveliso ezingenazingcingo ezikwibakala labathengi ziya kuthatha iimvavanyo zokuthobela kwaye abo bathobela imigangatho efanelekileyo baya kunikwa ukuba basebenzise uphawu lwe-CTIA kunye nokubetha iishelufa zevenkile yentengiso yonxibelelwano yaseMntla Melika.

I-CATL (i-CTIA eGunyaziweyo yoVavanyo lweLebhu) imele iilebhu ezivunyiweyo yi-CTIA ukuze zivavanywe kwaye zihlolwe.Iingxelo zovavanyo ezikhutshwe kwi-CATL ziya kuvunywa zonke yi-CTIA.Ngelixa ezinye iingxelo zovavanyo kunye neziphumo ezisuka kwi-non-CATL zingayi kuqatshelwa okanye zingabi nafikelelo kwi-CTIA.I-CATL evunyiweyo yi-CTIA iyahluka kumashishini kunye neziqinisekiso.I-CATL kuphela efanelekile kuvavanyo lokuthotyelwa kwebhetri kunye nokuhlolwa inokufikelela kwisatifikethi sebhetri sokuthotyelwa kwe-IEEE1725.

▍CTIA iMigangatho yoVavanyo lwebhetri

a) IMfuneko yeSiqinisekiso seSistim yeBattery Ukuthotyelwa kwe-IEEE1725-Isebenza kwiiNkqubo zeBhetri ezineseli enye okanye iiseli ezininzi ezidityaniswe ngokufanayo;

b) IMfuneko yeSiqinisekiso seSistim yeBattery Ukuthotyelwa kwe-IEEE1625- Isebenza kwiiSystems zeBattery ezineeseli ezininzi ezidityaniswe ngokufana okanye kuzo zombini ezihambelanayo kunye nochungechunge;

Iingcebiso ezifudumeleyo: Khetha ngaphezulu kwemigangatho yoqinisekiso ngokufanelekileyo kwiibhetri ezisetyenziswa kwiifowuni eziphathwayo kunye neekhompyuter.Musa ukusebenzisa kakubi i-IEE1725 kwiibhetri ezikwiiselfowuni okanye i-IEEE1625 kwiibhetri ezikwiikhompyutha.

▍Kutheni i-MCM?

●Itekhnoloji enzima:Ukusukela ngo-2014, i-MCM ibizimasa inkomfa yokupakisha ibhetri ebanjwa yi-CTIA e-US minyaka le, kwaye iyakwazi ukufumana uhlaziyo lwamva nje nokuqonda iindlela ezintsha zomgaqo-nkqubo malunga ne-CTIA ngendlela ekhawulezayo, echanekileyo nesebenzayo.

●Isiqinisekiso:I-MCM yiCATL evunyiweyo yi-CTIA kwaye ifanelekile ukwenza zonke iinkqubo ezinxulumene nesatifikethi kubandakanya uvavanyo, uphicotho lwefektri kunye nokufakwa kwengxelo.

Iibhetri ze-Lithium-ion zokuGcinwa kwamandla (i-GB / T 36276-2023) yakhululwa ekupheleni kukaDisemba 2023 kwaye iya kuphunyezwa ngoJulayi 1, 2024. Ngophuhliso olukhawulezayo lwemarike yokugcina amandla ebhetri ye-lithium-ion kwiminyaka yamuva nje, iingozi nazo bezisenzeka rhoqo.Ngokusekelwe kule nto, xa kuthelekiswa nenguqu ye-2018, isakhiwo esipheleleyo senguqu entsha sihlala singatshintshi, kodwa iimfuno zobugcisa zingqongqo, kwaye iimfuno zokuvavanya zibanzi.
Isakhiwo se-hierarchical yenkqubo yokugcina amandla ngolu hlobo lulandelayo: iiseli zixhunyiwe kwi-series kunye ne-parallel ukuze zenze imodyuli yeseli, iimodyuli zeeseli zixhunyiwe kwi-series kunye ne-parallel ukwenza i-cell cluster, i-cell cluster ixhunyiwe ngokufana ukwenza amandla ebhetri. inkqubo yokugcina, kunye neenkqubo zokugcina amandla ebhetri ziqhagamshelwe ngokunxuseneyo ukwenza isikhululo sokugcina amandla ebhetri.Ukusebenza kunye nokhuseleko lwenkqubo yebhetri ngundoqo wesiseko sokusebenza kwesikhululo sokugcina amandla.I-GB / T 36276-2023 ihlanganisa iiparitha eziphambili zokusebenza kunye nokhuseleko lokusebenza ukusuka kwinqanaba leeseli, iimodyuli ukuya kumaqela, kwaye ichaza ngokucacileyo iimfuno kwinqanaba ngalinye leebhetri.
Kwangaxeshanye, i-CPSC iphinde yakhupha umthetho wokugqibela owahlukileyo (88 FR 65296) ukuseka iimfuno zokuleyibheli ezilumkiso zokupakishwa kweiseli yeqhoshas okanye iibhetri ezinkozo (kubandakanya iibhetri ezipakishwe ngokwahlukeneyo kwiimveliso zabathengi) (iphunyezwe nge-21 kaSeptemba 2024)
