Ibhethri le-nickel-metal hydride elishajekayo (NiMH noma i-Ni–MH) liwuhlobo lwebhethri.Ukusabela kwekhemikhali ye-electrode ephozithivu kuyafana naleyo ye-nickel-cadmium cell (NiCd), njengoba bobabili zisebenzisa i-nickel oxide hydroxide (NiOOH).Esikhundleni se-cadmium, ama-electrode angalungile enziwa nge-alloy emunca i-hydrogen.Amabhethri e-NiMH angaba namandla aphindwe kabili kuya kathathu kumthamo wamabhethri e-NiCd anosayizi ofanayo, kanye nokuminyana kwamandla okungaphezulu kakhuluamabhethri e-lithium-ion, nakuba ngezindleko eziphansi.
Amabhethri e-nickel metal hydride awukuthuthukiswa ngaphezu kwamabhethri e-nickel-cadmium, ikakhulukazi ngoba asebenzisa insimbi ekwazi ukumunca i-hydrogen esikhundleni se-cadmium (Cd).Amabhethri e-NiMH anomthamo omkhulu kunamabhethri e-NiCd, anomphumela wenkumbulo ophawuleka kancane, futhi anobuthi obuncane ngoba awanayo i-cadmium.
I-Nimh Memory Effect yebhethri
Uma ibhethri lishajwa ngokuphindaphindiwe ngaphambi kokuba wonke amandla alo agciniwe aphele, umphumela wenkumbulo, owaziwa nangokuthi umphumela webhethri ovilaphayo noma inkumbulo yebhethri, kungenzeka.Njengomphumela, ibhethri izokhumbula umjikelezo wempilo owehlile.Ungase uqaphele ukuncipha okukhulu kwesikhathi sokusebenza ngesikhathi esilandelayo lapho usisebenzisa.Ezimweni eziningi, ukusebenza akuthinteki.
Amabhethri e-NiMH awanawo "umphumela wenkumbulo" ngomqondo oqinile, kodwa kanjalo namabhethri e-NiCd awanawo.Kodwa-ke, amabhethri e-NiMH, njengamabhethri e-NiCd, angathola ukuncipha kwamandla kagesi, okubuye kwaziwe ngokuthi ukucindezeleka kwamandla kagesi, kodwa umphumela ngokuvamile awubonakali kangako.Abakhiqizi batusa ukukhishwa ngezikhathi ezithile, okuphelele kwamabhethri e-NiMH okulandelwa ukushajwa kabusha okugcwele ukuze kuqedwe ngokuphelele ukuba nokwenzeka kwanoma yimuphi umphumela wokuphela kwamandla kagesi.
Ukushaja ngokweqile nokugcinwa okungafanele nakho kungalimaza amabhethri e-NiMH.Iningi labasebenzisi bebhethri le-NiMH alithintwa yilo mphumela wokuncipha kwamandla kagesi.Nokho, uma usebenzisa idivayisi isikhathi esifushane kuphela nsuku zonke, njengethoshi, umsakazo, noma ikhamera yedijithali, bese ushaja amabhethri, uzokonga imali.
Nokho, uma usebenzisa idivayisi efana nethoshi, umsakazo, noma ikhamera yedijithali isikhathi esifushane usuku nosuku bese ushaja amabhethri njalo ebusuku, uzodinga ukuvumela amabhethri e-NiMH ukuthi ahlehle njalo ngemva kwalokho.
Kumabhethri e-nickel-cadmium angatshajwa kabusha kanye ne-nickel-metal hybrid, umphumela wenkumbulo uyabonwa.Umphumela wenkumbulo weqiniso, ngakolunye uhlangothi, uvela ezikhathini ezingavamile kuphela.Ibhethri maningi amathuba okuthi likhiqize imithelela efana nje nomthelela wenkumbulo 'weqiniso'.Uyini umehluko phakathi kwakho kokubili?Lezo ngokuvamile zingezesikhashana kuphela futhi zingahlehliswa ngokunakekelwa okufanele kwebhethri, okubonisa ukuthi ibhethri lisasebenza.
Inkinga Yenkumbulo Yebhethri ye-Nimh
Amabhethri e-NIMH "awanankumbulo," okusho ukuthi awanayo le nkinga.Kube yinkinga ngamabhethri e-NiCd ngoba ukuchithwa kwengxenye okuphindaphindiwe kubangele "umphumela wenkumbulo" futhi amabhethri alahlekelwa amandla.Eminyakeni edlule, kuningi okuye kwabhalwa ngale ndaba.Awukho umthelela wenkumbulo kumabhethri esimanje we-NimH oyoke uwaqaphele.
Uma uzikhipha ngokucophelela endaweni efanayo izikhathi eziningi, ungase ubone ukuthi umthamo otholakalayo wehle ngenani elincane kakhulu.Uma uwakhipha uye kwelinye iphuzu bese uwashaja kabusha, nokho, lo mphumela uyasuswa.Ngenxa yalokho, awusoze wadinga ukukhipha amaseli akho e-NimH, futhi kufanele uzame ukuwagwema ngazo zonke izindleko.
Ezinye izinkinga zihunyushwa njengomphumela wenkumbulo:
Ukushaja ngokweqile isikhathi eside kubangela ukucindezeleka kwe-voltage-
Ukucindezeleka kwe-voltage kuyinqubo evamile ehlotshaniswa nomphumela wenkumbulo.Kulokhu, amandla okukhipha amandla ebhethri ehla ngokushesha kunokuvamile njengoba esetshenziswa, naphezu kweqiniso lokuthi umthamo ophelele uhlala ucishe ufane.Ibhethri libonakala liphelelwa ngokushesha kakhulu ezintweni zesimanje zikagesi eziqapha amandla kagesi ukuze zibonise ukushajwa kwebhethri.Ibhethri ibonakala ingabambeli ukushajwa kwayo okugcwele kumsebenzisi, okufana nomthelela wememori.Amadivayisi alayisha kakhulu, njengamakhamera edijithali nomakhalekhukhwini, athambekele kulolu daba.
Ukushajwa ngokweqile kwebhethri kubangela ukwakheka kwamakristalu amancane e-electrolyte kumapuleti, okuholela ekucindezelekeni kwamandla kagesi.Lawa angavala amapuleti, kubangele ukumelana okuphezulu kanye ne-voltage ephansi kwamanye amaseli ebhethri ngamanye.Ngenxa yalokho, ibhethri lilonke libonakala liphuma ngokushesha njengoba lawo maseli angawodwana ephuma ngokushesha futhi amandla ebhethri ehla ngokuzumayo.Ngenxa yokuthi amashaja amaningi akhohlisayo akhokhisa ngokweqile, lo mphumela uvame kakhulu.
I-Nimh Amathiphu Wokushaja Ibhethri
Kuma-electronics omthengi, amabhethri e-NiMH aphakathi kwamabhethri ajwayeleke ukushajwa.Ngenxa yokuthi izixazululo zamandla aphathekayo, adonsa kakhulu zidingeka kakhulu kwezinhlelo zebhethri, sikuhlanganisele lolu hlu lwamathiphu ebhethri le-NiMH!
Amabhethri e-NiMH ashajwa kanjani kabusha?
Uzodinga ishaja ethile ukuze ushaje ibhethri le-NiMH, njengoba ukusebenzisa indlela engalungile yokushaja ibhethri lakho kungalenza lingasebenzi.Ishaja yebhethri ye-iMax B6 iyindlela yethu ephezulu yokukhetha ukushaja amabhethri e-NiMH.Inezinhlobonhlobo zezilungiselelo nokucushwa kwezinhlobo ezahlukene zamabhethri futhi ingashaja amabhethri afika ku-15 cell NiMH amabhethri.Shaja amabhethri akho e-NiMH isikhathi esingekho ngaphezu kwamahora angu-20 ngesikhathi, njengoba ukushaja isikhathi eside kungalimaza ibhethri lakho!
Inombolo yezikhathi lapho amabhethri e-NiMH angashajwa khona kabusha:
Ibhethri elijwayelekile le-NiMH kufanele lihlale cishe kumjikelezo wokushaja/wokukhipha ongu-2000, kodwa ibanga lakho lingase lihluke.Lokhu kungenxa yokuthi awekho amabhethri amabili afanayo.Inani lemijikelezo ibhethri elizohlala kuyo linganqunywa ukuthi lisetshenziswa kanjani.Sekukonke, impilo yomjikelezo webhethri engu-2000 iyamangalisa ngeseli elishajwa kabusha!
Izinto Ongazicabangela Ngokushaja Ibhethri le-NiMH
●Indlela ephephe kunazo zonke yokushaja ibhethri lakho ukushaja kancane kancane.Ukuze wenze njalo, qiniseka ukuthi ushaja ngenani eliphansi kakhulu ukuze isikhathi sakho sokushaja sibe ngaphansi kwamahora angu-20, bese ukhipha ibhethri lakho.Le ndlela ihlanganisa ukushaja ibhethri lakho ngenani elingalishajeli ngokweqile kuyilapho usaligcina lishajiwe.
● Amabhethri e-NiMH akufanele ashajwe ngokweqile.Kalula nje, uma ibhethri selishajwe ngokugcwele, kufanele uyeke ukulishaja.Kunezindlela ezimbalwa zokunquma ukuthi ibhethri lakho selishajwe nini, kodwa kungcono ukulishiya eshajani yebhethri lakho.Amashaja amabhethri amasha "ahlakaniphile," athola izinguquko ezincane ku-Voltage/Temperature yebhethri ukukhombisa iseli egcwele ngokugcwele.
