Ukuqonda iibhetri zeNiMH

Ibhetri ye-NiMH lukhetho oludumileyo kwizicelo ezahlukeneyo, kubandakanya i-elektroniki yabathengi, izixhobo zombane, kunye nezithuthi zombane, ngenxa yoxinzelelo lwamandla aphezulu, ixabiso eliphantsi, kunye nobuhlobo bendalo.Njengeumenzi ophambili weebhetri ze-NiMH, sinikezela ngeenkonzo zebhetri ze-NiMH ezilungiselelwe ukuhlangabezana neemfuno ezithile zabathengi bethu.Iqela lethu leengcali lisebenza ngokusondeleyo kunye nomthengi ngamnye ukwenza isisombululo sebhetri esilungiselelwe iimfuno zabo ezizodwa.Yethuibhetri ye-NiMH eyenziwe ngokwezifisoiinkonzo zixhaswa kukuzinikela kwethu kumgangatho nokuthembeka.Nangona kunjalo, kubalulekile ukubahlawulisa ngokuchanekileyo ukuze ufumane okuninzi kwiibhetri ze-NiMH.

Intshayelelo esisiseko malunga nokuTshaja kwebhetri ye-NiMH

Ukusabela kakuhle kwe-electrode xa utshajaIbhetri yeNiMH: Ni(OH)2+OH-→NiOOH+H2O+e- Ukusabela okungalunganga kwe-electrode: M+H20+e-→MH+OH- Ukusabela kukonke: M+Ni(OH)2→MH+ NiOOH
Xa ibhetri ye-NiMH ikhutshwa, ukusabela kwe pi-electrode ene-ositiveNONE
Kule fomyula ingentla, i-M yi-alloy yokugcina i-hydrogen, kwaye i-MH yi-alloy yokugcina i-hydrogen apho ii-athomu ze-hydrogen zibhengezwa.Eyona nto isetyenziswa ngokuqhelekileyo yokugcina i-hydrogen alloy yiLaNi5.

Ibhetri ye-nickel-metal hydride ikhutshwe kakhulu: i-nickel hydroxide electrode (i-electrode ephilileyo)2H2O+2e-H2+2OH- i-electrode yokufunxa i-hydrogen (i-electrode enegative) H2+20H-2e→2H20 Xa ikhutshwe kakhulu, isiphumo se-net ye-reaction yebhetri iyonke ngu-zero.I-hydrogen ebonakala kwi-anode iya kuhlanganiswa ngokutsha kwi-electrode engalunganga, ekwagcina uzinzo lwenkqubo yebhetri.
Ukutshaja okusemgangathweni kwe-NiMH
Indlela yokutshaja ngokupheleleyo ibhetri ye-NiMH etywiniweyo ukuyihlawula nge-nominal constant current (0.1 CA) ixesha eliqingqiweyo.Ukuthintela ukugqithiswa kwexesha elide, i-timer kufuneka ilungiswe ukuyeka ukutshaja kwi-150-160% igalelo lomthamo (iiyure eziyi-15-16).Uluhlu lobushushu obusebenzayo kule ndlela yokutshaja ngu-0 ukuya +45 degrees Celsius.Ubuninzi bangoku yi-0.1 CA.Ixesha lokutshaja kakhulu kwebhetri akufuneki lidlule iiyure ezili-1000 kwiqondo lobushushu begumbi.

I-NiMH ikhawuleza ukutshaja
Enye indlela yokuhlawula ngokupheleleyo ibhetri ye-NiMH ngokukhawuleza ukuyihlawula ngokuqhubekayo ngokuqhubekayo kwe-0.3 CA ixesha elilinganiselwe.Isibali-xesha kufuneka simiselwe ukuphelisa ukutshaja emva kweeyure ezi-4, ezilingana ne-120% umthamo webhetri.Uluhlu lobushushu obusebenzayo kule ndlela yokutshaja yi +10 ukuya +45°C.

I-NiMH iyatshaja ngokukhawuleza
Le ndlela ihlawulisa i-V 450 - V 600 HR NiMH iibhetri ngexesha elincinci kunye nentlawulo eqhubekayo ye-0.5 - 1 CA.Ukusebenzisa i-timer control circuit ukuphelisa ukutshaja ngokukhawuleza akwanele.Ukwandisa ubomi bebhetri, sincoma ukusebenzisa i-dT/dt ukulawula ukuphela kwentlawulo.Ulawulo lwe-dT / dt kufuneka lusetyenziswe kwinqanaba lokunyuka kweqondo lokushisa kwe-0.7 ° C / min.Njengoko kuboniswe kwi-Fig. 24, ukuhla kwamandla ombane kunokuphelisa ukutshaja xa izinga lokushisa liphakama.–△V1) Isixhobo sokuphelisa intlawulo sinokusetyenziswa naso.Ixabiso lereferensi ye-△V isixhobo sokuphelisa siya kuba yi-5-10 mV/piece.Ukuba akukho nanye kwezi zixhobo zokuqhawula ezisebenzayo, isixhobo esongezelelweyo se-TCO2 siyafuneka.Xa isixhobo sokuphelisa ukutshaja ngokukhawuleza sisika umsinga wokutshaja, i-trickle charge ye-0.01-0.03CA kufuneka ivulwe ngoko nangoko.

I-NiMH iyatshaja
Ukusetyenziswa kakhulu kufuna ukuba ibhetri ihlale igcwaliswe ngokupheleleyo.Ukuhlawulela ukulahlekelwa kwamandla ngenxa yokuzikhupha, kucetyiswa ukuba usebenzise i-current ye-0.01-0.03 CA yokutshaja i-trickle.Uluhlu olufanelekileyo lobushushu bokutshaja amathontsi yi +10°C ukuya +35°C.Ukutshaja i-Trickle kungasetyenziselwa ukutshaja okulandelayo emva kokusebenzisa le ndlela ingentla.Umahluko kwintlawuliso yangoku kunye nesidingo sokubhaqwa kwentlawulo egcweleyo ebuthathaka kwenze itshaja ye-NiCd yoqobo ingafanelekanga kwiibhetri ze-NiMH.I-NiMH kwiitshaja ze-NiCd ziya kutshisa kakhulu, kodwa i-NiCd kwiitshaja ze-NiMH isebenza kakuhle.Iitshaja zale mihla zisebenza ngazo zombini iinkqubo zebhetri.

Inkqubo yokutshaja ibhetri ye-NiMH
Ukutshaja: Xa usebenzisa Ukuyeka ukuTshaja ngokuKhawuleza, ibhetri ayitshaji ngokupheleleyo emva kokuyekiswa kokuTshaja ngokukhawuleza.Ukuqinisekisa ukuhlawuliswa kwe-100%, isongezelelo senkqubo yokutshaja kufuneka yongezwe.Izinga lokutshaja ngokubanzi aligqithi kwi-0.3c trickle charger: ikwabizwa ngokuba kukutshaja ulondolozo.Ngokuxhomekeke kwiimpawu zokuzikhupha zebhetri, izinga lentlawulo ye-trickle liphantsi kakhulu.Ukuba ibhetri iqhagamshelwe kwitshaja kwaye itshaja ivuliwe, itshaja iya kutshaja ibhetri ngexabiso elithile ngexesha lokutshaja ukuze ibhetri ihlale igcwele ngokupheleleyo.

Abasebenzisi abaninzi bebhetri baye bakhalazela ukuba ubomi bufutshane kunoko bekulindelekile, kwaye ingxaki isenokuba kwitshaja.Iitshaja zabathengi ezinexabiso eliphantsi zithande ukutshaja ngendlela engeyiyo.Ukuba ufuna iitshaja zexabiso eliphantsi, ungaseta ixesha lesimo sokutshaja kwaye ukhuphe ibhetri ngoko nangoko emva kokuba igcwaliswe ngokupheleleyo.

Ukuba ubushushu betshaja budikidiki, ibhetri ingagcwala.Ukususa nokutshaja iibhetri kwangethuba phambi kokusetyenziswa ngakunye kungcono kunokuzishiya kwitshaja ukuze zisetyenziswe ekugqibeleni.

Iimpazamo zokuTshaja eziqhelekileyo emaziphetshwe

Xa utshaja iibhetri ze-NiMH, kukho iimpazamo ezimbalwa eziqhelekileyo ekufuneka zithintelwe ukugcina impilo yebhetri kunye nokusebenza:

Ukuhlawula ngaphezulu: Njengoko kukhankanyiwe ngaphambili, ukutshaja kakhulu kunokuba yingozi kwibhetri.Ngalo lonke ixesha sebenzisa itshaja ekrelekrele enophawu lweDelta-V ukunqanda ukutshaja.
Ukusebenzisa itshaja engalunganga: Ayizizo zonke iitshaja ezifanelekileyo kwiibhetri zeNiMH.Itshaja eyenzelwe ezinye iikhemistri zebhetri, ezifana neNiCd (Nickel-Cadmium) okanye iLi-ion (iLithium-ion), inokonakalisa iibhetri zeNiMH.Ngalo lonke ixesha qinisekisa ukuba usebenzisa itshaja eyenzelwe ngokukodwa iibhetri ze-NiMH.
Ukutshaja kumaqondo obushushu aphezulu: Iibhetri ze-NiMH kumaqondo obushushu aphezulu kakhulu okanye aphantsi anokubangela umonakalo kwaye anciphise ixesha lokuphila.Iibhetri ze-NiMH kufuneka zitshajwe kwiqondo lobushushu begumbi (malunga ne-20°C okanye i-68°F).
Ukusebenzisa iibhetri ezonakalisiweyo: Ukuba ibhetri ibonakala yonakele, idumbile, okanye iyavuza, musa ukuzama ukuyitshaja.Yilahle ngokufanelekileyo kwaye ubeke entsha endaweni yayo.

Ukugcina impilo yebhetri ye-NiMH kwixesha elide

Ukongeza kwintlawulo efanelekileyo, ukulandela ezi ngcebiso kunokukunceda ugcine impilo kunye nokusebenza kweebhetri zakho ze-NiMH:

Gcina iibhetri ngokufanelekileyo: Gcina iibhetri zakho ze-NiMH kwindawo epholileyo, eyomileyo, kude nelanga elithe ngqo kunye nemithombo yobushushu.Kuphephe ukuzigcina kwindawo yokufuma okanye kwindawo yobushushu obugqithisileyo.
Kuphephe ukukhupha okunzulu: Ukukhupha ngokupheleleyo iibhetri ze-NiMH kunokubangela umonakalo kwaye kunciphise ubomi babo.Zama ukuzitshaja kwakhona phambi kokuba ziphele ngokupheleleyo.
Yenza ulondolozo lwamaxesha ngamaxesha: Licebo elilungileyo ukukhupha iibhetri zakho ze-NiMH ukuya malunga ne-1.0V ngeseli nganye qho kwiinyanga ezimbalwa kwaye emva koko uzihlawulele usebenzisa itshaja ye-Delta-V.Oku kunceda ukugcina amandla kunye nokusebenza kwabo.
Tshintsha iibhetri ezindala: Ukuba ubona ukwehla okubonakalayo ekusebenzeni kwebhetri okanye umthamo, kusenokuba lixesha lokutshintshela iibhetri ezintsha.

Ukuqukumbela

Ukutshaja ngokufanelekileyo kunye nokugcina iibhetri zakho ze-NiMH ziqinisekisa ubomi obude, ukusebenza, kunye nexabiso elipheleleyo.Njengomthengi we-B2B okanye umthengi weebhetri ze-NiMH, ukuqonda ezi ndlela zibalaseleyo ziya kukunceda wenze izigqibo ezizizo xa ukhangela iibhetri ze-NiMH zeshishini lakho.Ukusebenzisa iindlela ezichanekileyo zokutshaja kunye nokuphepha iimpazamo eziqhelekileyo, unokwandisa ubomi kunye nokusebenza kweebhetri ozithengayo, uzuze ishishini lakho kunye nabathengi bakho.
