Batire yowonjezeredwa ya nickel-metal hydride (NiMH kapena Ni-MH) ndi mtundu wa batire.Ma elekitirodi abwino a ma elekitirodi amafanana ndi a nickel-cadmium cell (NiCd), popeza onse amagwiritsa ntchito nickel oxide hydroxide (NiOOH).M'malo mwa cadmium, ma elekitirodi olakwika amapangidwa ndi alloy-absorbing alloy.Mabatire a NiMH amatha kuwirikiza kawiri kapena katatu kuchuluka kwa mabatire a NiCd ofanana kukula kwake, komanso kuchulukira kwamphamvu kwambiri kuposamabatire a lithiamu-ion, ngakhale pamtengo wotsika.
Mabatire a nickel metal hydride amawongolera kuposa mabatire a nickel-cadmium, makamaka chifukwa amagwiritsa ntchito chitsulo chomwe chimatha kuyamwa haidrojeni m'malo mwa cadmium (Cd).Mabatire a NiMH ali ndi mphamvu zambiri kuposa mabatire a NiCd, amakhala ndi kukumbukira kosaoneka bwino, ndipo alibe poizoni chifukwa alibe cadmium.
Nimh Battery Memory Effect
Ngati batire imayimbidwa mobwerezabwereza mphamvu zake zonse zosungidwa zisanathe, zotsatira za kukumbukira, zomwe zimadziwikanso kuti ulesi wa batri kapena kukumbukira kwa batri, zikhoza kuchitika.Zotsatira zake, batire imakumbukira kuchepa kwa moyo.Mutha kuwona kuchepa kwakukulu kwa nthawi yogwiritsira ntchito mukadzagwiritsanso ntchito.Nthawi zambiri, magwiridwe antchito sakhudzidwa.
Mabatire a NiMH alibe "memory effect" mwatsatanetsatane, komanso mabatire a NiCd.Komabe, mabatire a NiMH, monga mabatire a NiCd, amatha kukumana ndi kuchepa kwamagetsi, komwe kumadziwikanso kuti voltage depression, koma zotsatira zake nthawi zambiri siziwoneka.Opanga amalimbikitsa kutulutsa kwanthawi zina, kutulutsa kwathunthu kwa mabatire a NiMH ndikutsatiridwa ndi recharge yonse kuti athetse kuthekera kwa kutha kwa mphamvu iliyonse yamagetsi.
Kuchulukitsitsa ndi kusungirako kosayenera kungawonongenso mabatire a NiMH.Ambiri mwa ogwiritsa ntchito mabatire a NiMH sakhudzidwa ndi izi.Komabe, ngati mungogwiritsa ntchito chipangizochi kwakanthawi kochepa tsiku lililonse, monga tochi, wailesi, kapena kamera ya digito, ndiyeno mumalipira mabatire, mumasunga ndalama.
Komabe, ngati mugwiritsa ntchito chipangizo ngati tochi, wailesi, kapena kamera ya digito kwakanthawi kochepa tsiku lililonse ndikulipiritsa mabatire usiku uliwonse, muyenera kusiya mabatire a NiMH kutsika nthawi ndi nthawi.
M'mabatire osakanizidwa a nickel-cadmium ndi nickel-metal, kukumbukira kumawonedwa.Chowonadi chokumbukira kukumbukira, kumbali ina, chimapezeka mwa apo ndi apo.Batire imatha kutulutsa zotuluka zomwe zimangofanana ndi "zowona" zokumbukira.Kodi pali kusiyana kotani pakati pa ziwirizi?Izi nthawi zambiri zimakhala zosakhalitsa ndipo zimatha kusinthidwa ndi chisamaliro choyenera cha batri, kusonyeza kuti batire ikugwirabe ntchito.
Vuto la Memory Battery ya Nimh
Mabatire a NIMH ndi "opanda kukumbukira," kutanthauza kuti alibe vutoli.Linali vuto ndi mabatire a NiCd chifukwa kutulutsa pang'ono mobwerezabwereza kumapangitsa "kukumbukira" ndipo mabatire adataya mphamvu.Kwa zaka zambiri, zambiri zalembedwa pankhaniyi.Palibe kukumbukira mabatire amakono a NimH omwe mungazindikire.
Ngati muwatulutsa mosamala kumalo omwewo kangapo, mungazindikire kuti mphamvu yomwe ilipo yatsika ndi yochepa kwambiri.Mukawatulutsa kumalo ena ndikubwezeretsanso, komabe, izi zimachotsedwa.Zotsatira zake, simudzasowa kutulutsa ma cell anu a NimH, ndipo muyenera kuyesetsa kupewa chilichonse.
Nkhani zina zimatanthauzidwa ngati kukumbukira kukumbukira:
Kuchulukitsa kwa nthawi yayitali kumayambitsa kupsinjika kwa ma voltage-
Kukhumudwa kwa Voltage ndi njira yodziwika bwino yokhudzana ndi kukumbukira kukumbukira.Pamenepa, mphamvu yotulutsa batire imatsika mofulumira kuposa momwe imagwiritsidwira ntchito, ngakhale kuti mphamvu yonseyi imakhalabe yofanana.Batire ikuwoneka kuti ikutha mofulumira kwambiri mu zipangizo zamakono zamakono zomwe zimayang'anitsitsa mphamvu yamagetsi kuti iwonetse mtengo wa batri.Batire likuwoneka kuti silikugwira ntchito yake yonse kwa wogwiritsa ntchito, zomwe zimafanana ndi kukumbukira kukumbukira.Zipangizo zodzaza kwambiri, monga makamera a digito ndi mafoni am'manja, ndizosavuta kuthana ndi nkhaniyi.
Kuchulukirachulukira kwa batire kumapangitsa kupanga makristalo ang'onoang'ono a electrolyte pama mbale, zomwe zimapangitsa kutsika kwamagetsi.Izi zimatha kutseka ma mbale, zomwe zimapangitsa kuti pakhale kukana kwambiri komanso kutsika kwamagetsi m'maselo ena a batri.Zotsatira zake, batire yonseyo ikuwoneka kuti ikutuluka mwachangu pomwe ma cell amatuluka mwachangu ndipo mphamvu ya batire imatsika mwadzidzidzi.Chifukwa chakuti ma charger ambiri amachulukirachulukira, izi ndizofala kwambiri.
Maupangiri Opangira Battery a Nimh
Pamagetsi ogula, mabatire a NiMH ndi ena mwa mabatire omwe amatha kuchangidwanso.Chifukwa mayankho amagetsi osunthika, otayira kwambiri akufunika kwambiri pamabatire, taphatikiza mndandanda waupangiri wa batri wa NiMH!
Kodi mabatire a NiMH amachajitsidwa bwanji?
Mufunika chojambulira chapadera kuti muwononge batire ya NiMH, chifukwa kugwiritsa ntchito njira yolakwika yolipirira batire yanu kungapangitse kuti ikhale yopanda ntchito.IMax B6 Battery Charger ndiye kusankha kwathu kopambana pakulipiritsa mabatire a NiMH.Ili ndi makonda osiyanasiyana ndi masinthidwe amitundu yosiyanasiyana ya batri ndipo imatha kulipiritsa mabatire mpaka 15 ma cell a NiMH.Limbani mabatire anu a NiMH osapitilira maola 20 nthawi imodzi, chifukwa kulipiritsa kwanthawi yayitali kumatha kuwononga batire lanu!
Nambala yanthawi zomwe mabatire a NiMH amatha kuyitanitsa:
Batire yokhazikika ya NiMH iyenera kupitilira kuzungulira kwa 2000 / kutulutsa, koma mtunda wanu ukhoza kusiyana.Izi zili choncho chifukwa palibe mabatire awiri ofanana.Kuchuluka kwa nthawi yomwe batire idzakhalire imatha kutsimikiziridwa ndi momwe imagwiritsidwira ntchito.Ponseponse, moyo wa batire wa 2000 ndi wosangalatsa kwambiri pama cell omwe amatha kuchangidwanso!
Zinthu Zoyenera Kuziganizira Zokhudza Kuyimitsa Battery ya NiMH
●Njira yotetezeka kwambiri yolipirira batire yanu ndikungothamangitsa pang'onopang'ono.Kuti muchite izi, onetsetsani kuti mukulipiritsa pamtengo wotsika kwambiri kuti nthawi yonse yolipiritsa ikhale yosachepera maola 20, kenako chotsani batire lanu.Njira iyi ikuphatikizapo kulipiritsa batri yanu pamlingo woti simukulipiritsa mukadali ndi chaji.
●Mabatire a NiMH sayenera kuchulukitsidwa.Mwachidule, batire ikangodzaza, muyenera kusiya kulitcha.Pali njira zingapo zodziwira nthawi yomwe batire yanu yadzaza kwathunthu, koma ndibwino kuti muyisiye ku charger yanu.Ma charger atsopano ndi "anzeru," amazindikira kusintha kwakung'ono kwa Voltage/Kutentha kwa batire kusonyeza cell yodzaza kwathunthu.
