Ibhetri egcwalisekayo yenickel-metal hydride (NiMH okanye iNi–MH) luhlobo lwebhetri.Ukusabela kweekhemikhali ze-electrode ezilungileyo kufana naleyo yeseli ye-nickel-cadmium (NiCd), njengoko bobabini basebenzisa i-nickel oxide hydroxide (NiOOH).Esikhundleni se-cadmium, i-electrodes engalunganga yenziwe nge-alloy efunxa i-hydrogen.Iibhetri ze-NiMH zinokuba nokuphinda-phindwe kabini ukuya kwesithathu umthamo weebhetri zeNiCd ezinobungakanani obufanayo, kunye noxinano lwamandla oluphezulu kakhulu kunoko.iibhetri ze-lithium-ion, nangona ngexabiso eliphantsi.
Iibhetri ze-nickel metal hydride ziphuculo ngaphezu kweebhetri ze-nickel-cadmium, ngakumbi kuba zisebenzisa isinyithi esinokufunxa i-hydrogen endaweni ye-cadmium (Cd).Iibhetri ze-NiMH zinomthamo ophezulu kuneebhetri ze-NiCd, zineempembelelo zememori ezingaphawuleki kangako, kwaye azinatyhefu encinane kuba azinayo i-cadmium.
Isiphumo seMemori yebhetri yeNimh
Ukuba ibhetri ihlawulwe ngokuphindaphindiweyo ngaphambi kokuba onke amandla ayo agciniweyo aphelelwe, umphumo wememori, owaziwa ngokuba yimpembelelo yebhetri eyonqenayo okanye imemori yebhetri, ingenzeka.Ngenxa yoko, ibhetri iya kukhumbula umjikelo wobomi obunciphile.Unokuqaphela ukuncipha okukhulu kwexesha lokusebenza kwixesha elizayo xa ulisebenzisa.Kwiimeko ezininzi, ukusebenza akuchaphazeleki.
Ibhetri ye-NiMH ayinayo "impembelelo yenkumbulo" ngeyona ndlela ingqongqo, kodwa ngokunjalo neebhetri zeNiCd azinayo.Nangona kunjalo, iibhetri ze-NiMH, njengeebhetri ze-NiCd, zinokufumana ukuncipha kwamandla ombane, okwabizwa ngokuba kukudandatheka kombane, kodwa umphumo uhlala ungabonakali kangako.Abavelisi bancomela ngamaxesha athile, ukukhutshwa okupheleleyo kweebhetri ze-NiMH ezilandelwa kukutshaja ngokupheleleyo ukuphelisa ngokupheleleyo ukuba nokwenzeka kwaso nasiphi na isiphumo sokuphela kwamandla ombane.
Ukutshaja kakhulu kunye nogcino olungafanelekanga lunokwenzakalisa iibhetri ze-NiMH.Uninzi lwabasebenzisi bebhetri ye-NiMH abachatshazelwa yile mpembelelo yokuncipha kombane.Nangona kunjalo, ukuba usebenzisa isixhobo ixesha elifutshane yonke imihla, esifana nesibane, unomathotholo, okanye ikhamera yedijithali, uze uhlawule iibhetri, uya konga imali.
Nangona kunjalo, ukuba usebenzisa isixhobo esinje ngetotshi, unomathotholo, okanye ikhamera yedijithali ixesha elifutshane suku ngalunye kwaye emva koko uhlawule iibhetri rhoqo ebusuku, kuya kufuneka uvumele iibhetri ze-NiMH zihle rhoqo ngoku kwaye emva koko.
Kwiibhetri ze-nickel-cadmium ezihlawulekayo kunye ne-nickel-metal, umphumo wememori uyabonwa.Isiphumo sokwenyani senkumbulo, kwelinye icala, senzeka kuphela ngezihlandlo ezinqabileyo.Ibhetri kunokwenzeka ukuba ivelise iziphumo ezithi zifane nje nesiphumo senkumbulo 'yenyani'.Yintoni umahluko phakathi kwezi zimbini?Ezo zihlala zezokwexeshana kuphela kwaye zinokutshintshwa ngokhathalelo olululo lwebhetri, nto leyo ebonisa ukuba ibhetri isasebenza.
Ingxaki yeMemori yebhetri yeNimh
Iibhetri ze-NIMH "ziinkumbulo mahala," okuthetha ukuba abanayo le ngxaki.Ibiyingxaki ngeebhetri ze-NiCd kuba ukukhutshwa okuphindaphindiweyo kubangele "impembelelo yememori" kwaye iibhetri zilahlekelwe ngumthamo.Ukutyhubela iminyaka, zininzi izinto eziye zabhalwa ngalo mbandela.Akukho siphumo sokukhumbula kwiibhetri zanamhlanje zeNimH oya kuze uziphawule.
Ukuba uzikhupha ngononophelo kwindawo enye amaxesha amaninzi, unokuqaphela ukuba umthamo okhoyo unciphe ngexabiso elincinci kakhulu.Xa uzikhuphela kwenye indawo uze uphinde uzitshaje, nangona kunjalo, esi siphumo siyasuswa.Ngenxa yoko, awusoze ufune ukukhupha iiseli zakho ze-NimH, kwaye kuya kufuneka uzame ukuyinqanda ngazo zonke iindleko.
Eminye imiba itolikwe njengesiphumo senkumbulo:
Ukutshaja ixesha elide kubangela ukudakumba kwamandla ombane-
Ukuxinezeleka kwe-voltage yinkqubo eqhelekileyo ehambelana nefuthe lememori.Kule meko, i-voltage ye-output yebhetri yehla ngokukhawuleza kunesiqhelo njengoko isetyenziswa, nangona umthamo uphela uhlala ufana.Ibhetri ibonakala ikhupha ngokukhawuleza kwizixhobo zombane zanamhlanje ezibeka esweni amandla ombane ukubonisa intlawulo yebhetri.Ibhetri ibonakala ngathi ayibambanga intlawulo yayo epheleleyo kumsebenzisi, efana nefuthe lememori.Izixhobo ezinomthwalo omkhulu, ezinjengeekhamera zedijithali kunye neeselfowuni, ziqhelekile kulo mbandela.
Ukutshaja ngokuphindaphindiweyo kwebhetri kubangela ukubunjwa kweekristale ezincinci ze-electrolyte kwiipleyiti, okukhokelela ekudakaleni kombane.Ezi zinokuvala iipleyiti, zibangele ukuxhathisa okuphezulu kunye nombane ophantsi kwezinye iiseli zebhetri nganye.Ngenxa yoko, ibhetri xa iyonke ibonakala ikhupha ngokukhawuleza njengoko ezo seli zodwa ziphuma ngokukhawuleza kwaye amandla ombane ebhetri ehla ngokukhawuleza.Ngenxa yokuba uninzi lwabathengi lusebenzisa itshaja ngokugqithisileyo, esi siphumo sixhaphake kakhulu.
Iingcebiso zokuTjaja ibhetri yeNimh
Kwi-electronics yabathengi, iibhetri ze-NiMH ziphakathi kwezona bhetri ziqhelekileyo ezinokutshajwa.Ngenxa yokuba izisombululo zamandla eziphathwayo, zokukhupha amanzi aphezulu zifunwa kakhulu kwizicelo zebhetri, sikuhlanganisele olu luhlu lweengcebiso zebhetri yeNiMH!
Zihlaziywa njani iibhetri ze-NiMH?
Uya kudinga itshaja ethile ukutshaja ibhetri ye-NiMH, njengoko ukusebenzisa indlela engalunganga yokutshaja ibhetri yakho kunokuyenza ingabi namsebenzi.Itshaja yebhetri ye-iMax B6 yeyona nto iphambili yokukhetha ukutshaja iibhetri zeNiMH.Ineendlela ezahlukeneyo zokuseta kunye nokucwangciswa kweentlobo ezahlukeneyo zebhetri kwaye inokuhlawula iibhetri ukuya kuthi ga kwi-15 yeebhetri ze-NiMH.Tshaja iibhetri zakho ze-NiMH ngaphandle kweeyure ezingama-20 ngexesha, njengoko ukutshaja ixesha elide kunokwenzakalisa ibhetri yakho!
Inani lamaxesha iibhetri ze-NiMH ezinokutshajwa kwakhona:
Ibhetri ye-NiMH esemgangathweni kufuneka ihlale malunga ne-2000 imijikelezo yentlawulo / yokukhupha, kodwa imayile yakho inokwahluka.Oku kungenxa yokuba akukho bhetri zimbini zifana.Inani lemijikelo eya kuhlala ihleli ibhetri inokumiselwa ngendlela esetyenziswa ngayo.Lilonke, ubomi bomjikelo webhetri wama-2000 buyamangalisa kwiseli ephinda igcwaliseke!
Izinto ekufuneka uziqwalasele malunga nokuTshaja kwebhetri ye-NiMH
●Eyona ndlela ikhuselekileyo yokutshaja ibhetri yakho kukutshaja kancinci.Ukwenza njalo, qiniseka ukuba uhlawulisa ngelona zinga lisezantsi ukuze ixesha lakho lokutshaja libe ngaphantsi kweeyure ezingama-20, kwaye emva koko uyisuse ibhetri yakho.Le ndlela ibandakanya ukutshaja ibhetri yakho ngesantya esingahlawulisi kakhulu ngeli lixa uyigcinayo.
● Iibhetri zeNiMH akufunekanga zigcwaliswe ngokugqithisileyo.Ukubeka nje ngokulula, xa ibhetri igcwaliswe ngokupheleleyo, kufuneka uyeke ukuyitshaja.Kukho iindlela ezimbalwa zokumisela ukuba ibhetri yakho igcwaliswe nini ngokupheleleyo, kodwa kungcono ukuyishiya kwitshaja yebhetri yakho.Iitshaja ezintsha zebhetri "zihlakaniphile," zijonga utshintsho oluncinci kwiVoltage/Temperature yebhetri ukubonisa iseli egcwele ngokupheleleyo.
