Ungakuqinisekisa kanjani ukuphepha kwangaphakathi kwamabhethri e-lithium-ion,
Amabhethri e-Lithium Ion,

▍Iyini I-CTIA CERTIFICATION?

I-CTIA, isifinyezo se-Cellular Telecommunications and Internet Association, yinhlangano yomphakathi engenzi nzuzo eyasungulwa ngo-1984 ngenjongo yokuqinisekisa ukuhlomula kwabaqhubi, abakhiqizi nabasebenzisi. I-CTIA iqukethe bonke opharetha base-US nabakhiqizi abavela kumasevisi omsakazo weselula, kanye namasevisi edatha angenantambo nemikhiqizo. Isekelwe yi-FCC (Federal Communications Commission) kanye neCongress, i-CTIA yenza ingxenye enkulu yemisebenzi nemisebenzi eyayisetshenziselwa ukwenziwa uhulumeni. Ngo-1991, i-CTIA yakha uhlelo lokuhlola lomkhiqizo olungachemile, oluzimele nolwendawo eyodwa kanye nesitifiketi somkhakha ongenazintambo. Ngaphansi kwesistimu, yonke imikhiqizo engenantambo esebangeni labathengi izothatha izivivinyo zokuthobela imithetho futhi leyo ethobelana namazinga afanele izovunyelwa ukusebenzisa ukumaka kwe-CTIA nokushayisana kwamashalofu ezitolo emakethe yezokuxhumana yaseNyakatho Melika.

I-CATL (CTIA Authorized Testing Laboratory) imele amalebhu agunyazwe yi-CTIA ukuze ahlolwe futhi abuyekezwe. Imibiko yokuhlola ekhishwe ku-CATL izogunyazwa yonke yi-CTIA. Nakuba eminye imibiko yokuhlola kanye nemiphumela evela ku-non-CATL ngeke ibonwe noma ingakwazi ukufinyelela ku-CTIA. I-CATL egunyazwe yi-CTIA iyahlukahluka ezimbonini nasekutholeni izitifiketi. I-CATL kuphela efanelekela ukuhlolwa nokuhlolwa kokuthobela ibhethri ekwazi ukufinyelela esitifiketini sebhethri ukuze ihambisane ne-IEEE1725.

▍CTIA Amazinga Wokuhlola Ibhethri

a) Isidingo Sokuthola Isitifiketi Sohlelo Lwebhethri Ukuthobela IEEE1725— Kusebenza Ezinhlelweni Zebhethri ezineseli elilodwa noma amaseli amaningi axhunywe ngokuhambisana;

b) Isidingo Sokuthola Isitifiketi Sohlelo Lwebhethri Ukuthobelana ne-IEEE1625— Kusebenza Ezinhlelweni Zebhethri ezinamaseli amaningi axhunywe ngokuhambisana noma kokubili ngokuhambisana nochungechunge;

Amathiphu afudumele: Khetha ngenhla kwamazinga wesitifiketi ngokufanelekile kumabhethri asetshenziswa omakhalekhukhwini namakhompyutha. Ungasebenzisi kabi i-IEE1725 kumabhethri kumakhalekhukhwini noma i-IEEE1625 kumabhethri akukhompyutha.

▍Kungani i-MCM?

●Ubuchwepheshe obuqinile:Kusukela ngo-2014, i-MCM ibihambela inkomfa yamaphakethe webhethri ebanjwa yi-CTIA e-US minyaka yonke, futhi iyakwazi ukuthola isibuyekezo sakamuva futhi iqonde amathrendi enqubomgomo emisha mayelana ne-CTIA ngendlela esheshayo, enembayo nesebenzayo.

●Ukufaneleka:I-MCM iyi-CATL egunyazwe yi-CTIA futhi ifaneleka ukwenza zonke izinqubo ezihlobene nesitifiketi okuhlanganisa ukuhlola, ukuhlola kwasefekthri nokulayisha umbiko.

Njengamanje, izingozi eziningi zokuphepha zamabhethri e-lithium-ion zenzeka ngenxa yokwehluleka kwesifunda sokuvikela, okubangela ukubaleka kwebhethri okushisayo futhi kubangele umlilo nokuqhuma. Ngakho-ke, ukuze ubone ukusetshenziswa okuphephile kwebhethri ye-lithium, ukwakheka kwesekethe yokuvikela kubaluleke kakhulu, futhi zonke izinhlobo zezinto ezibangela ukwehluleka kwebhethri le-lithium kufanele zicatshangelwe. Ngaphezu kwenqubo yokukhiqiza, ukwehluleka ngokuyisisekelo kubangelwa izinguquko ezimweni ezimbi kakhulu zangaphandle, njengokukhokhiswa ngokweqile, ukukhipha ngokweqile kanye nezinga lokushisa eliphezulu. Uma le mingcele ibhekwa ngesikhathi sangempela futhi izinyathelo zokuzivikela ezihambisanayo zizothathwa lapho zishintsha, ukuvela kokugijima okushisayo kungagwenywa. Idizayini yokuphepha yebhethri ye-lithium ihlanganisa izici eziningana: ukukhethwa kweseli, ukuklama kwesakhiwo kanye nomklamo wokuphepha osebenzayo we-BMS.Kunezici eziningi ezithinta ukuphepha kweseli lapho ukukhethwa kwezinto zeseli kuyisisekelo. Ngenxa yezakhiwo ezahlukene zamakhemikhali, ukuphepha kuyahlukahluka ezintweni ezihlukahlukene ze-cathode zebhethri ye-lithium. Isibonelo, i-lithium iron phosphate imise okwe-olivine, eqinile futhi akulula ukudilika. I-Lithium cobaltate ne-lithium ternary, nokho, ziyisakhiwo esinezingqimba okulula ukuwa. Ukukhethwa kwesihlukanisi nakho kubaluleke kakhulu, njengoba ukusebenza kwayo kuhlobene ngokuqondile nokuphepha kweseli. Ngakho-ke ekukhethweni kweseli, hhayi imibiko yokutholwa kuphela kodwa nenqubo yokukhiqiza yomkhiqizi, izinto zokwakha kanye nemingcele yazo kufanele kucatshangelwe. Ukufakwa ngaphakathi kweseli nendawo ebiyelwe; Ukufakwa kwe-insulation phakathi kwezigxobo zesigxobo kanye nendawo ebiyelwe; Isikhala sikagesi se-PCB nebanga le-creepage, idizayini yezintambo zangaphakathi, ukwakheka komhlaba, njll.
