Ukuqinisekisa njani ukhuseleko lwangaphakathi lweebhetri ze-lithium-ion,
Iibhetri zeLithium Ion,

▍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— iFaneka kwiiNkqubo zeBattery 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 kwiifowuni eziphathwayo 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.

Okwangoku, uninzi lweengozi zokhuseleko lweebhetri ze-lithium-ion zenzeke ngenxa yokungaphumeleli kwesiphaluka sokukhusela, okubangela ukuba i-thermal runway yebhetri kwaye ibangele umlilo kunye nokuqhuma. Ke ngoko, ukuze uqaphele ukusetyenziswa okukhuselekileyo kwebhetri ye-lithium, uyilo lwesekethe yokhuseleko lubaluleke kakhulu, kwaye zonke iintlobo zezinto ezibangela ukusilela kwebhetri ye-lithium kufuneka zithathelwe ingqalelo. Ukongeza kwinkqubo yokuvelisa, ukungaphumeleli ngokusisiseko kubangelwa utshintsho kwiimeko ezigqithisileyo zangaphandle, ezifana nokugqithisa, ukukhutshwa ngokugqithisileyo kunye nokushisa okuphezulu. Ukuba ezi parameters zibekwe esweni ngexesha langempela kwaye amanyathelo okukhusela ahambelanayo aya kuthathwa xa atshintsha, ukuvela kwe-thermal runaway kunokugwenywa. Uyilo lokhuseleko lwebhetri ye-lithium lubandakanya iinkalo ezininzi: ukukhethwa kweeseli, ukuyila kwesakhiwo kunye nokuyila ukhuseleko olusebenzayo lwe-BMS.Kukho izinto ezininzi ezichaphazela ukhuseleko lweseli apho ukhetho lwezixhobo zeseli lusisiseko. Ngenxa yeempawu zeekhemikhali ezahlukeneyo, ukhuseleko luyahluka kwizinto ezahlukeneyo ze-cathode zebhetri ye-lithium. Ngokomzekelo, i-lithium iron phosphate imile okwe-olivine, ezinzileyo kwaye akukho lula ukudilika. I-Lithium cobaltate kunye ne-lithium ternary, nangona kunjalo, ziyisakhiwo esinemaleko ekulula ukuwa. Ukukhetha ukwahlula kubaluleke kakhulu, njengoko ukusebenza kwayo kuhambelana ngokuthe ngqo nokhuseleko lweseli. Ke ngoko ekukhetheni iiseli, ayizizo kuphela iingxelo zokubhaqwa kodwa nenkqubo yemveliso yomenzi, imathiriyeli kunye nemilinganiselo yazo iya kuqwalaselwa. I-Insulation phakathi kweseli kunye ne-enclosure; Ukufakwa kwe-insulation phakathi kweepali kunye ne-enclosure; Isithuba sombane se-PCB kunye nomgama we-creepage, uyilo lwangaphakathi lwe-wiring, uyilo lokumisa, njl.
