Ukushaja iphakethe lebhethri elisekelwe ku-nickel elinamaseli amathathu ngeshaja ye-Li-Ion [pdf]

Isingeniso: Ingozi Yokuxuba Amakhemistri Webhethri

Ezweni elisheshayo lama-electronics aphathwayo nempahla yebhizinisi, ukuqinisekisa ukuthi idivayisi yakho inikwe amandla ngendlela efanele akuxoxiswana ngayo. Kumabhizinisi athembele kumathuluzi asuka kuzikena eziphathwa ngesandla ukuya kumadivayisi akhethekile okuxhumana, ibhethri liwukuphila okuqhubekayo kokusebenza. Umbuzo ovamile, kodwa ongase ube yingozi, ophakamayo owokuthi ishaja elula kodwa engafanele ingasetshenziswa ekuncinyaneni—ikakhulukazi, ungakwazi yini ukushaja iphakethe lebhethri le-nickel-metal hydride (NiMH) elinamaseli amathathu ngeshaja evamile ye-lithium-ion (Li-Ion)? Impendulo emfushane ingucha onamandla, futhi ukuqonda ukuthi "kungani" kubalulekile ekuphepheni, ubuqotho bedivayisi, kanye nokugcina ukusebenza kahle ancike kukho amabhizinisi esimanje, njengalawo asebenzisa inkundla ye-Mewayz ukuze enze lula ukusebenza kwawo.

Umehluko Oyisisekelo Phakathi Kwe-NiMH nokushaja kwe-Li-Ion

Isizathu esiyinhloko sokuthi lawa makhemistri amabhethri amabili angahambisani sisezindleleni zawo zokushaja eziyisisekelo. Ishaja ye-Li-Ion isebenza kusetshenziswa i-algorithm ye-consultant-current, constant-voltage (CCCV). Iqala isebenzisa amandla angashintshi ebhethri ize ifike ku-voltage ephezulu enembile (isb., 4.2V ngeseli), bese ishintshela kumodi ye-voltage engaguquki, okuvumela i-current ukuthi inciphe njengoba ibhethri lishajwa ngokugcwele. Ngokuphambene, amabhethri asekelwe ku-nickel njenge-NiMH ngokuvamile ashajwa ngokuqhubekayo. Ukushaja kwabo okugcwele akubonwa ngokuphakama kwe-voltage, kodwa ngokwehla kancane kwe-voltage noma ukunyuka kwezinga lokushisa. Ukusebenzisa ishaja ye-Li-Ion kuphakethe le-NiMH kusho ukusebenzisa uhlobo lokushaja oluklanyelwe inqubo yamakhemikhali ehluke ngokuphelele, okuholela emiphumeleni eyingozi.

Izingozi: Kusuka Ekwehliseni Ukuphila Kwesikhathi Kuya Ekuhlulekeni Okubalulekile

Ukuzama ukushaja iphekhi ye-NiMH enamaseli amathathu (ene-voltage yegama engu-3.6V) ngeshaja ye-Li-ion (engalindela amandla kagesi acishe abe ngu-11.1V ngephakethe le-Li-ion lamaseli amathathu) igcwele ingozi. Ukungafani kwamandla kagesi kukodwa kuyinkinga enkulu, kodwa izingozi zijula kakhulu.

• Ukushaja Kakhulu kanye Nokushisa Kakhulu: Ishaja ye-Li-Ion ngeke isithole kahle isimo sokushajwa esigcwele sebhethri le-NiMH. Izoqhubeka nokuphusha i-current, okuholela ekushajweni okukhulu kakhulu. Lokhu kubangela ukunqwabelana kokushisa okukhulu, okungalimaza isakhiwo sangaphakathi sebhethri, kukhiphe amagesi ayingozi, futhi ezimeni ezimbi kakhulu, kuholele ekugqabukeni noma ekushiseni.
• Ukulahleka Kwekhono Ngaphambi Kwesikhathi: Ngisho nangaphandle kokwehluleka okuyinhlekelele, ukushaja okungafanele okungaguquki kwehlisa isithunzi ngokushesha amaseli e-NiMH. Ingcindezi yokushajwa ngokweqile ifinyeza kakhulu impilo yebhethri iyonke, kunciphisa inani lemijikelezo yokushajwa engakwazi ukuyibekezelela futhi kunciphise amandla ayo okubamba ishaji.
• Ukwehluleka Kwendlela Yokuphepha: Amabhethri e-NiMH awanawo amasekhethi ayinkimbinkimbi okuvikela akhelwe ngaphakathi ajwayelekile kumaphakethe e-Li-ion. Bathembele ngokuphelele kushaja ukuthi inqamule ukushaja ngendlela efanele. Ishaja ye-Li-Ion ngeke inikeze lo msebenzi wokuphepha obalulekile.

Imikhuba Engcono Kakhulu Yokushaja Amaphekhi Ebhethri Asekelwe ku-Nickel

Ukuze uqinisekise ukuphepha kanye nokwandisa ukutshalwa kwezimali kumpahla yebhizinisi lakho, ukuthobela izinkombandlela zomkhiqizi kubalulekile. Njengoba nje i-OS yebhizinisi efana ne-Mewayz ikulethela ukuhleleka nokusebenza kahle ekusebenzeni kwakho, ukusebenzisa ishaja efanele kuletha ukwethembeka ekulawuleni kwakho amandla.

"Ukusebenzisa ishaja edizayinelwe ikhemistri yebhethri ehlukile kufana nokusebenzisa ukhiye ongalungile ekhikhini; okuhle kakhulu, ngeke kusebenze, futhi okubi kakhulu, kuzodala umonakalo omkhulu. Hlala uqondanisa ishaja nezimfuneko ezithile zebhethri."

Ukuphela kwendlela ephephile yokushaja iphakethe lebhethri elisuselwa ku-nickel ukusebenzisa ishaja eklanyelwe yona ngokukhethekile. Lawa mashaja ahlelwa ngendlela efanele—ngokuvamile athola ukwehla kwamandla kagesi acashile (-ΔV) abonisa ukushajwa okuphelele—futhi alinganiselwe amandla kagesi afanele kanye namazinga amanje. Ebhizinisini eliphethe amadivaysi amaningi, ukusebenzisa isistimu yokulebula ecacile yamashaja namabhethri kungavimbela ukuhlangana okumba eqolo nokuyingozi, kuqinisekise ukuthi isikhathi sokungasebenzi siyancipha futhi ukuphepha kwezisebenzi kubekwe kuqala.

Isiphetho: Ukubeka Eqhulwini Ukuphepha Nokuhambisana

Ebhizinisini, ukusebenza kahle kubalulekile, kodwa akufanele neze kufike ngezindleko zokuphepha. Umzamo wokushaja ibhethri le-NiMH elinamaseli amathathu ngeshaja ye-Li-Ion uyisinqamuleli esiyingozi esifaka engozini kokubili. Umehluko obalulekile wamakhemikhali phakathi kwalawa mabhethri udinga amaphrothokholi athile wokushaja. Ngokuqonda izingozi—kusuka ekusebenzeni okuncishisiwe kuye ezingozini zomlilo ezingaba khona—kanye nokuzibophezela ekusebenziseni amashaja agunyazwe umkhiqizi kuphela, amabhizinisi angavikela impahla yawo kanye nabantu bawo. Le ndlela eneziyalo yokuphathwa kwezisetshenziswa, kungakhathaliseki ukuthi inika amandla amadivayisi noma ukuqondisa imisebenzi nge-Mewayz, iyona eyakha umsebenzi oqinile nophumelelayo.

Imibuzo Evame Ukubuzwa
