Nkhani - Momwe Mungalimbitsire Mabatire a NiMH Moyenera

Monga wogula wa B2B kapena wogula mabatire a NiMH (Nickel-Metal Hydride), ndikofunikira kumvetsetsa njira zabwino zolipirira mabatirewa.Kulipira koyenera kumatsimikizira kuti mabatire a NiMH adzakhala ndi moyo wautali, ntchito yabwino, ndi kusunga mphamvu zawo pakapita nthawi.M'nkhaniyi, tikambirana mbali zazikulu za kulipiritsa mabatire a NiMH, kuphatikiza njira zoyenera zolipirira, zolakwa zomwe wamba, komanso momwe mungasungire thanzi la batri pakapita nthawi.

Kumvetsetsa Mabatire a NiMH

Mabatire a NiMH ndi chisankho chodziwika bwino pamagwiritsidwe osiyanasiyana, kuphatikiza zamagetsi ogula, zida zamagetsi, ndi magalimoto amagetsi, chifukwa cha kuchuluka kwawo kwamagetsi, kutsika mtengo, komanso kusamala zachilengedwe.Monga awopanga mabatire a NiMH, timapereka ntchito za batri za NiMH kuti tikwaniritse zosowa za makasitomala athu.Gulu lathu la akatswiri limagwira ntchito limodzi ndi kasitomala aliyense kuti apange yankho la batri logwirizana ndi zosowa zawo zapadera.Zathumakonda a NiMH batirentchito zimathandizidwa ndi kudzipereka kwathu pakuchita bwino komanso kudalirika.Komabe, ndikofunikira kuwalipiritsa moyenera kuti apindule kwambiri ndi mabatire a NiMH.

Chiyambi Chachiyambi cha NiMH Battery Charging

Positive ma elekitirodi mukamalipiraBattery ya NiMH: Ni(OH)2+OH-→NiOOH+H2O+e- Negative electrode reaction: M+H20+e-→MH+OH- Overall reaction: M+Ni(OH)2→MH+ NiOOH
Batire ya NiMH ikatulutsidwa, zomwe positive electrode: NiOOH+H2O+e-→Ni(OH)2+OH- Negative electrode: MH+OH-→M+H2O+e- Overall reaction: MH+NiOOH→M+Ni(OH)2
M'njira yomwe ili pamwambayi, M ndi aloyi yosungiramo haidrojeni, ndipo MH ndi alloy yosungirako haidrojeni momwe maatomu a haidrojeni amagulitsidwa.Chomwe chimagwiritsidwa ntchito kwambiri ndi hydrogen storage alloy ndi LaNi5.

Batire ya nickel-metal hydride yatha: nickel hydroxide electrode (positive electrode)2H2O+2e-H2+2OH- hydrogen absorption electrode (negative electrode) H2+20H-2e→2H20 Ikatulutsidwa mopitirira muyeso, zotsatira za batire yonse ndi ziro.The haidrojeni kuwonekera pa anode adzakhala latsopano pamodzi pa elekitirodi zoipa, amenenso amasunga bata dongosolo batire.
Mtengo wamtengo wapatali wa NiMH
Njira yolipirira batire yosindikizidwa ya NiMH ndikuyilipiritsa ndi mphamvu yanthawi zonse (0.1 CA) kwakanthawi kochepa.Kuti mupewe kuchulukitsidwa kwa nthawi yayitali, chowerengera chiyenera kusinthidwa kuti chiyimitse kulipiritsa pa 150-160% mphamvu yakulowetsa (maola 15-16).Kutentha koyenera kwa njira yolipirirayi ndi 0 mpaka +45 digiri Celsius.Pakali pano ndi 0.1 CA.Nthawi yowonjezereka ya batri sayenera kupitirira maola 1000 kutentha kwa chipinda.

NiMH imathandizira kuyitanitsa
Njira ina yolipirira batire ya NiMH mwachangu ndikulipiritsa ndi 0.3 CA nthawi yocheperako.Chowerengeracho chiyenera kukhazikitsidwa kuti chizimitsa kuyitanitsa pakatha maola anayi, omwe ndi ofanana ndi 120% mphamvu ya batire.Kutentha koyenera kwa njira yolipirirayi ndi +10 mpaka +45°C.

Kuthamanga kwa NiMH
Njirayi imayitanitsa mabatire a V 450 - V 600 HR NiMH m'nthawi yochepa yokhala ndi 0.5 - 1 CA.Kugwiritsa ntchito chowongolera chowongolera nthawi kuti muthe kuyitanitsa mwachangu sikokwanira.Kuti muchulukitse moyo wa batri, timalimbikitsa kugwiritsa ntchito dT/dt kuwongolera kutha kwa charger.Kuwongolera kwa dT/dt kuyenera kugwiritsidwa ntchito pa kutentha kwa 0.7°C/mphindi.Monga momwe tawonetsera mkuyu. 24, kutsika kwa magetsi kumatha kuthetsa kulipira pamene kutentha kumakwera.-△V1) Chida choyimitsa ndalama chingagwiritsidwenso ntchito.Mtengo wazomwe -△Chida choyimitsa V chizikhala 5-10 mV/chidutswa.Ngati palibe chimodzi mwazida izi cholumikizira chimagwira ntchito, chipangizo chowonjezera cha TCO2) chikufunika.Chida chothimitsa chacharge mwachangu chikadula charging, mphamvu ya 0.01-0.03CA iyenera kuyatsidwa nthawi yomweyo.

Kuthamangitsa kwa NiMH
Kugwiritsa ntchito kwambiri kumafuna kuti batire ikhalebe yokwanira.Kuti mulipire kutaya mphamvu chifukwa chodziyimitsa nokha, tikulimbikitsidwa kugwiritsa ntchito yapano ya 0.01-0.03 CA pakulipiritsa pang'onopang'ono.Kutentha koyenera kwa kuthamangitsa kutsika ndi +10°C mpaka +35°C.Kulipiritsa kwa Trickle kumatha kugwiritsidwa ntchito pakulipiritsa kotsatira mutagwiritsa ntchito njira yomwe ili pamwambapa.Kusiyana kwa kachulukidwe kachaji kameneka komanso kufunikira kodziwikiratu zachaji champhamvu kwambiri kunapangitsa kuti charger yoyambirira ya NiCd ikhale yosakwanira mabatire a NiMH.Ma charger a NiMH mu NiCd azitentha kwambiri, koma NiCd mu NiMH charger imagwira ntchito bwino.Ma charger amakono amagwira ntchito ndi ma batire onse.

Njira yopangira batire ya NiMH
Kulipira: Mukamagwiritsa ntchito Quick Charge Stop, batire silimangidwa mokwanira pambuyo poyimitsidwa.Kuti mutsimikizire kuti mukulipira 100%, chowonjezera cha njira yolipirira chiyeneranso kuwonjezeredwa.Mtengo wolipiritsa nthawi zambiri sudutsa 0.3c trickle charger: yomwe imadziwikanso kuti kuyitanitsa kukonza.Kutengera mawonekedwe a batire yodziyimitsa yokha, kutsika kwamphamvu kumakhala kotsika kwambiri.Malingana ngati batire ili yolumikizidwa ku charger ndipo chojambulira chayatsidwa, chojambuliracho chimatcha batri pamlingo wapanthawi yokonza kuti batire ikhale yokwanira.

Ogwiritsa ntchito mabatire ambiri adandaula kuti moyo wawo ndi waufupi kuposa momwe amayembekezera, ndipo cholakwika chingakhale ndi chojambulira.Ma charger otsika mtengo amakonda kuyitanitsa molakwika.Ngati mukufuna ma charger otsika mtengo, mutha kukhazikitsa nthawi yolipirira ndikutulutsa batriyo ikangotha.

Ngati kutentha kwa charger kuli kofunda, batire ikhoza kukhala yodzaza.Kuchotsa ndi kulitcha mabatire mwamsanga musanagwiritse ntchito kuli bwino kusiyana ndi kuwasiya mu charger kuti muwagwiritse ntchito.

Zolakwa Zodziwika Zoyenera Kuzipewa

Mukamalipira mabatire a NiMH, pali zolakwika zingapo zomwe ziyenera kupewedwa kuti mukhale ndi thanzi labwino komanso magwiridwe antchito:

Kuchulukitsa: Monga tanena kale, kuchulukitsitsa kumatha kuwononga batire.Nthawi zonse gwiritsani ntchito charger yanzeru yokhala ndi kuzindikira kwa Delta-V kuti mupewe kuchulutsa.
Kugwiritsa ntchito charger yolakwika: Si ma charger onse omwe ali oyenera mabatire a NiMH.Chaja yopangira ma makemitolo ena a batire, monga NiCd (Nickel-Cadmium) kapena Li-ion (Lithium-ion), imatha kuwononga mabatire a NiMH.Nthawi zonse onetsetsani kuti mumagwiritsa ntchito charger yopangidwira mabatire a NiMH.
Kulipira pa kutentha kwambiri: Mabatire a NiMH pa kutentha kwambiri kapena kutsika kwambiri amatha kuwononga ndikuchepetsa moyo.Mabatire a NiMH ayenera kuchajitsidwa kutentha kwa chipinda (pafupifupi 20°C kapena 68°F).
Kugwiritsa ntchito mabatire owonongeka: Ngati batire lawonongeka, latupa, kapena likutha, musayese kulitchaja.Tayani moyenerera ndi kulowetsamo chatsopano.

Kusunga Thanzi la Battery la NiMH mu Nthawi Yaitali

Kuphatikiza pa kulipiritsa koyenera, kutsatira malangizowa kungakuthandizeni kukhalabe ndi thanzi labwino komanso magwiridwe antchito a mabatire anu a NiMH:

Sungani mabatire moyenera: Sungani mabatire anu a NiMH pamalo ozizira, owuma, kutali ndi kuwala kwa dzuwa ndi kutentha.Pewani kuzisunga m'malo otentha kwambiri kapena kutentha kwambiri.
Pewani kutulutsa kwambiri: Kutulutsa mabatire a NiMH kwathunthu kumatha kuwononga ndikuchepetsa moyo wawo.Yesetsani kuziwonjezera zisanathe.
Kukonza nthawi ndi nthawi: Ndibwino kuti mutulutse mabatire anu a NiMH mpaka pafupifupi 1.0V pa selo iliyonse miyezi ingapo ndikuwalipiritsanso pogwiritsa ntchito charger ya Delta-V.Izi zimathandiza kusunga mphamvu ndi ntchito zawo.
Sinthani mabatire akale: Mukawona kutsika kwakukulu kwa magwiridwe antchito kapena kuchuluka kwa batri, itha kukhala nthawi yosintha mabatire ndi ena atsopano.

Mapeto

Kuyitanitsa moyenera ndi kusamalira mabatire anu a NiMH kumatsimikizira moyo wautali, magwiridwe antchito, ndi mtengo wonse.Monga wogula wa B2B kapena wogula mabatire a NiMH, kumvetsetsa bwino izi kudzakuthandizani kupanga zisankho mwanzeru pofufuza mabatire a NiMH pabizinesi yanu.Pogwiritsa ntchito njira zolondola zolipirira ndikupewa zolakwika zomwe wamba, mutha kukhathamiritsa moyo ndi magwiridwe antchito a mabatire omwe mumagula, kupindulitsa bizinesi yanu ndi makasitomala anu.

Wopereka Battery Wanu Wodalirika wa NiMH

Fakitale yathu ili ndi makina apamwamba kwambiri ndipo imagwiritsa ntchito katswiri waluso wodzipereka kuti apange mabatire apamwamba a NiMH omwe amakwaniritsa zosowa za makasitomala athu.Timatsatira njira zowongolera zowongolera pamlingo uliwonse wopanga kuti tiwonetsetse kuti mabatire athu ndi otetezeka, odalirika komanso okhalitsa.Kudzipereka kwathu pakuchita bwino kwatipatsa mbiri monga ogulitsa odalirika a mabatire a NiMH pamakampani.Tikuyembekezera kukutumikirani ndikukupatsani mabatire abwino kwambiri a NiMH.Timapereka ma batire amtundu wa NiMH pamabatire angapo a NiMH.Phunzirani zambiri kuchokera m'munsimu tchati.
