Yintoni iFloat Voltage?

Amandla ombane eFloat yinqanaba lamandla ombane elisetyenziswa kwibhetri egcweleyo ukugcina ukutshajiswa kwayo ngokuzikhulula{0}}ukuzikhupha. Lo mbane wolondolozo uthintela ukutshajwa ngaphantsi kunye nokutshaja, igcina ibhetri ikulungele ukusetyenziswa ngokukhawuleza kwiinkqubo zamandla ezigciniweyo, izixhobo zikaxakeka, kunye nofakelo lwamandla ahlaziyekayo.

Iibhetri azihlali zihlawulwe ngonaphakade. Naxa zicinyiwe kuwo nawuphi na umthwalo, zonke iibhetri zizifumana{1}}zizikhupha{2}}ilahleko kancinane yentlawulo ngenxa yentshukumo yangaphakathi yemichiza. I-Lead-ibhetri zeasidi ziphulukana ne-3-5% yomthamo wazo ngenyanga kwiqondo lobushushu begumbi, ngelixa ezinye iikhemistri ze-lithium ziphulukana ne-1-3%.

Ukutshaja okudadayo kusombulula oku ngokusebenzisa amandla ombane angatshintshiyo, asezantsi azalisa kanye oko ibhetri iphulukene nayo ngokuzikhupha ngokwakho{0}}. Itshaja kunye nebhetri zisebenza ngokunxuseneyo, kunye netshaja ebonelela ngoku nje okwaneleyo ngoku ukugcina ibhetri kwindawo epheleleyo ngaphandle kokunyanzelisa umsinga ogqithisileyo ongonakalisa iiseli.

Ingqikelelo iba ngundoqo kwizicelo ezilindileyo. Ukunikezelwa kwamandla angenakuphazamiseka kumaziko edatha afuna iibhetri kwi-100% umthamo xa igridi ingaphumeleli. Iinkqubo zokukhanyisa ezingxamisekileyo kufuneka zisebenze ngoko nangoko ngexesha lokuphela kombane. Ezi meko zifuna iibhetri ezihlala zingasebenzi iinyanga kodwa zihlale zitshajiwe{4} ngokuchanekileyo ukuba ukuhambisa amandla ombane edadayo.

Float Voltage

Iindidi zebhetri ezahlukeneyo zifuna amandla ombane okudada okwahlukileyo okwahlukileyo, kwaye ukusebenzisa amandla ombane angalunganga kunokunciphisa kakhulu ubomi bebhetri okanye kudala iingozi zokhuseleko.

Ilead{{0}ibhetri zeasidi, kuquka izandyondyo, iAGM, kunye nokwahluka kwejeli,{1}}zisekwe kakuhle uluhlu lwamandla ombane adadayo. Kwi-25℃(77℃F), umgangatho umalunga ne-2.25 ukuya kwi-2.30 volts kwiseli nganye. Kwibhetri ye-12V eqhelekileyo kunye neeseli ezintandathu, oku kuguqulela kwi-13.5-13.8V.

Ilothe ekhukulayo{0}ibhetri zeasidi zikholisa ukudada kwi-13.4V (2.23V ngeseli), ngaphantsi kancinane kunoguquko olutywiniweyo ukunciphisa ilahleko yamanzi kwigesi ye-electrolyte. Iibhetri zeAGM zisebenza ngokukhululekileyo kwi-13.5-13.6V, ngelixa iibhetri zejeli zikhetha i-13.1-13.3V ngenxa yobuntununtunu kwi-voltage engaphezulu.

Ezi xabiso azinasizathu. Kumandla ombane edadayo, ibhetri yamkele ubuncinci bangoku{1}}kancinci ngaphantsi kwe-1% yomthamo wayo weyure amp{3}}. Ibhetri eyi-100Ah inokuzoba kuphela i-0.5-1 amp ngexesha lokutshaja okudadayo, okwaneleyo ukumelana nokuzikhupha ngaphandle koxinzelelo lwekhemistry yebhetri.

Iqondo lobushushu lichaphazela kakhulu amandla ombane wokudada okudadayo. Iintshukumo ze electrochemical kwilothe{1}}iibhetri zeasidi zikhawuleza ngobushushu kwaye zicotha ngokubanda. Imbuyekezo yobushushu bomgangatho woshishino imalunga ne -3.9mV ngedigri nganye ngeseli. Kwibhetri ye-12V, loo nto imalunga -23mV ngesidanga kwipakethi yonke.

Qwalasela umzekelo osebenzayo: Ibhetri ye-12V ekhukulisekileyo ene-13.4V yombane edadayo kwi-25 degree. Ukuba ubushushu be-ambient bunyuka ukuya kuma-35℃(ukunyuka kwe-10 degree), umbane we-float ohlawulelwayo uba yi-13.17V. Ngaphandle kolu hlengahlengiso, amandla ombane aphezulu kumaqondo obushushu aphakamileyo anokubangela irhasi egqithisileyo kunye nokulahleka kwamanzi. Ngakolunye uhlangothi, kwi-15 degree, i-voltage ye-float kufuneka inyuke ukuya kwi-13.63V ukuthintela ukutshaja ngaphantsi kweemeko ezipholileyo.

Iibhetri zeLithium zibonisa umfanekiso onzima ngakumbi. Ngelixa iibhetri {{1} zeasidi ziyilwe ngokutshaja okudadayo engqondweni, iikhemistri ze-lithium{2}}ingakumbi i-lithium-i-ion-ifuna uqwalaselo olucokisekileyo phambi kokuba ifake amandla ombane ahlala edadayo.

I-LiFePO4 (i-Lithium Iron Phosphate) iibhetri ziyakwazi ukunyamezela ukutshaja kwe-float xa zilungiswe kakuhle. I-voltage ye-float ekhuthazwayo isuka kwi-3.35 ukuya kwi-3.45V ngeseli nganye (13.4-13.8V kwipakethi ye-12V). Nangona kunjalo, kunye neeseli ze-LiFePO4 zifumana ukuguga okukhawulezileyo xa zigcinwe kumbane ophezulu ixesha elide.

Iiseli ze-lithium - ezisemgangathweni (i-NMC, iikhemistri zeNCA) zijongene nemingcipheko enkulu. Ezi seli zidla ngokuhlawulisa ukuya kuthi ga kwi-4.2V ngeseli nganye, kodwa ukuzibamba kulo mbane ngokuqhubekayo kubangela uxinzelelo kwizinto ze-electrode. I-cathode idlula utshintsho lwesakhiwo, i-lithium plating ingenzeka kwi-anode, kunye neempendulo zecala zikhawuleza ukubola kwe-electrolyte.

Nantsi aphoitshaja yebhetri ye-lithium ionuyilo lubaluleka. Iitshaja zebhetri ye-lithium ion ezisemgangathweni azisebenzisi ngokusemthethweni ukutshaja okudadayo. Endaweni yoko, basebenzisa iqhinga "lombane wogcino"{2}}ukutshaja ukuya mhlawumbi kwi-3.9-4.0V ngeseli nganye baze baqhawule, baqhagamshele kuphela xa amandla ombane ehla ngaphantsi komqobo. Oku kuthintela uxinzelelo lombane olungagungqiyo lokutshaja kwefloat eqhelekileyo.

Iinkqubo zolawulo lwebhetri (BMS) kwiibhetri ze-lithium zibeka iliso kwiivolthi zeeseli ngokuqhubekayo. Xa kuzanywa ukutshaja okudadayo, i-BMS kufuneka iqinisekise iiseli ezilungelelene ngokugqibeleleyo kunye nolawulo lwamandla ombane oluchanekileyo. Nokuba i-50-100mV ngaphezulu kwamandla ombane acetyiswayo inokubangela ukuthotywa okukhawulezileyo.

Intsingiselo esebenzayo: uninzi lwabavelisi bebhetri ye-lithium ion bacebisa ngokukodwa ngokuchasene nokutshaja okuqhubekekayo kwebhetri ye-lithium{0}}iion. Endaweni yoko, bacebisa "phezulu{2}}phezulu" ukutshaja okanye ugcino nge80-90% yemo yentlawulo yezicelo zexesha elide zokulinda.

Float Voltage

Umbane odadayo akakho wodwa-linqanaba lokugqibela lenkqubo yokutshaja yesigaba sesithathu-esetyenziswa uninzi lweetshaja zebhetri zanamhlanje kwilothe{2}}iasidi kunye nezinye iikhemistri zelithium.

Inqanaba lobuninzi lihambisa ubuninzi bangoku ukubuyisela ngokukhawuleza umthamo webhetri. Xa ibhetri ichithwa kakhulu{1}}yithi, ngaphantsi kwe-80% umthamo{3}}inokwamkela amazinga aphezulu angoku. Itshaja enobungakanani obufanelekileyo iya kuzisa i-15-25% yomthamo webhetri kwii-amps. Ibhetri ye-100Ah inokufumana i-15-25 amps ngexesha lokutshaja isambuku.

Umbane uyenyuka ngokuthe chu ngexesha lokutshaja isambuku njengoko imeko yebhetri isanda. Kwibhetri ye-asidi eyi-12V ekhokelayo, amandla ombane anokunyuka ukusuka kwi-11.5V xa ekhutshiwe ngokunzulu ukuya malunga ne-14.4V ekupheleni kwesigaba esikhulu. Itshaja igcina amandla akhoyo ngelixa amandla ombane alandela ukwamkelwa kwebhetri.

Malunga ne-80% yomthamo webhetri ubuyiselwa ngexesha lokutshaja isambuku. Eli nqanaba likhawuleza kakhulu{2}}ibhetri ekhutshwe ngokunzulu eyi-100Ah inokugqiba ukutshaja isambuku kwiiyure ezi-3-5 ngetshaja eyi-20-amp.

Njengoko ibhetri isondela kwi-80-}90% umthamo, ukukwazi kwayo ukwamkela okwangoku kuyancipha. Itshaja itshintshela kwimowudi yokufunxa, ibambe amandla ombane ngokungaguquguqukiyo (ngokuqhelekileyo i-14.4-14.8V ye-12V ye-lead-asidi) ngelixa langoku licima ngokwendalo.

Ngexesha lokufunxa, ukutshaja kwangoku kunokwehla ukusuka kwii-amps ezili-15 ukuya kwii-amps ezi-5, emva koko iye kwii-amps ezi-2 njengoko ibhetri isondela kumthamo opheleleyo. Ukuchaphazeleka kweekhemikhali kwiipleyiti zebhetri kuthoba isantya{4}}indawo ezisebenzayo ziyaxhaphaka, kwaye ukuxhathisa kwangaphakathi konyuka kancinane.

Eli nqanaba lithatha ixesha elide kunobuninzi ngaphandle kokubuyisela kuphela i-10-20% yomthamo. Ibhetri ye-100Ah efanayo inokuchitha 3-iiyure ezi-4 kwimowudi yokufunxa. Itshaja ngokuqhelekileyo ibeka iliso yangoku, ilindele ukuba yehle ngaphantsi komgubasi-mhlawumbi i-C/50 (ii-amps ezi-2 zebhetri eyi-100Ah) -phambi kokutshintsha ukuze idada.

Nje ukuba ukufunxa kugqitywe, itshaja inciphisa amandla ombane ukuya kwinqanaba lokudada. Kumzekelo wethu we-12V ekhokelayo{2}}yeasidi, amandla ombane ehla ukusuka kwi-14.4V ukuya kwi-13.5V. Eyangoku ngokukhawuleza iwela kumanqanaba amancinci{6}kaninzi ngaphantsi kwe-1 amp.

Ibhetri ngoku "iphumle" ihlawulwe ngokupheleleyo. Amandla ombane edadayo asezantsi anqanda ukutshaja okuphezulu{{1} kwangoku okunokubangela igesi kwiibhetri ezizaliswe ngamanzi okanye uxinzelelo kwiibhetri ezitywiniweyo. Ubuncinci obukhoyo buthatha indawo yebhetri ekulahlekayo kuyo{3}}ukuzikhupha.

Itshaja zangoku-zezigaba ezithathu zingahlala kwimowudi yokudada ngokungenasiphelo. Ibhetri eqhagamshelwe kwitshaja edadayo efanelekileyo inokuhlala iinyanga okanye iminyaka, isoloko ikulungele ukuzisa umthamo opheleleyo xa kuyimfuneko. Oku kwenza ukuba ukutshaja okudadayo kube ngokufanelekileyo kwiibhetri ezilindileyo kwiinkqubo ze-UPS, izibane zikaxakeka, kunye neenkqubo ze-alam.

Amaziko eenkcukacha axhomekeke kakhulu kulawulo olululo lwamandla ombane adadayo. Ufakelo oluqhelekileyo lwe-UPS lunokubandakanya amashumi eebhetri ze-12V kuthotho ukwenza i-480V okanye ngaphezulu kwamandla ombane ebhasi ye-DC. Ezi bhetri zidada ngokuqhubekayo, ngamanye amaxesha iminyaka phakathi kweziganeko zokukhutshwa.

Iibhetri ze-UPS zihlala zigcina iibhetri kumenzi{0}}ivolthi edadayo echaziweyo{1}}kaninzi yi-2.27V ngeseli yeVRLA (ivalve{3}}ilothe elawulwayo{4}}iasidi) iibhetri. Izinzwa zobushushu zilungisa lo mbane ngokuqhubekayo. I-480V UPS eneebhetri ezilishumi elinambini{9}}zevolti kuthotho ifuna ulawulo lombane oluchanekileyo kuzo zonke iiseli ezingama-240.

Umceli mngeni uqina ngokuguga kwebhetri. Njengoko iibhetri zikhula,{1}}amazinga azo azikhuphayo anokonyuka, efuna amandla ombane adadayo ahlukileyo. Iisistim ze-UPS ezikwinqanaba eliphezulu zisebenzisa-umtya wokujongwa kwamandla ombane ukuze zibone iibhetri ezonakeleyo ezizoba ngokugqithisileyo kwi-float yangoku{4}}uphawu lokuphuhlisa iibhulukhwe ezimfutshane okanye zomisiwe{5}iiseli.

Ngaphandle-kufakelo lwelanga kwigrid luzisa imiceli mngeni yokutshaja okudadayo. Iibhetri zichitha iintsuku okanye iiveki zigcwaliswe ngokupheleleyo ngexesha lelanga, emva koko ziphume ngexesha elongezelelekileyo lemozulu yamafu.

Izilawuli zentlawulo yelanga zisebenzisa ii-algorithms ezintsonkothileyo zokudada. Emini, nje ukuba iibhetri zifikelele kwintlawulo epheleleyo, umlawuli wehlisa amandla ombane wephaneli ukuya kwinqanaba lokudada. Oku kuthintela ukutshaja ngokugqithisileyo ngelixa uvumela iiphaneli ukuba zifake amandla kwimithwalo yasekhaya ngokuthe ngqo. Ebusuku, xa iiphaneli zingavelisi mandla, ukutshaja kwefloat ngokucacileyo kuyeka, kwaye iibhetri ziqalisa ukutshajwa.

Umahluko ophambili kwizicelo ze-UPS kukukhwela ibhayisekile. Iibhetri zelanga zinokudada iiyure ezisi-8 ukuya kwezili-12 mihla le, zikhuphe ubusuku bonke, emva koko zitshaje ngosuku olulandelayo. Le pateni ifuna imbuyekezo yobushushu eyomelele ngakumbi, njengoko ubushushu bebhetri bunokujinga kakhulu phakathi kwemini nobusuku.

Iibhetri zemoto zibonelela ngemeko eyahlukileyo yokutshaja okudadayo. Xa injini isebenza, i-alternator ihlawulisa kumbane omninzi (14.2-14.4V). Iialternatha zale mihla, nangona kunjalo, zibandakanya izilawuli ezikrelekrele ezehlisa amandla ombane nje ukuba ibhetri isondele ekutshajisweni, ngokusisiseko zibonelela ngokutshaja okudadayo ngelixa uqhuba.

Iinkqubo zebhetri zaselwandle zihlala zahlula iibhetri zendlu (zezibane kunye ne-electronics) kwiibhetri zokuqala. Iibhetri zendlu zisenokuhlala kwintlawulo edadayo ukusuka kumandla aselunxwemeni okanye iipaneli zelanga ngelixa isikhephe sihleli simile. Iitshaja ezisemgangathweni zaselwandle zibonelela ngokutshaja okuninzi-ebhankini, kunye nesethingi yamandla ombane edadayo ezimeleyo kwiibhanki ezohlukeneyo.

Ukufumana i-voltage edadayo ekunene kufuna ingqalelo kwizinto ezininzi ezingaphaya komgangatho wombane osisiseko.

Ngaphandle kwembuyekezo yeqondo lokushisa, iibhetri zihlupheka. Ibhetri ekwigumbi lezixhobo zedigri ezingama-40 ifumana i-13.8V ifumana uxinzelelo olufanayo njengebhetri kwiqondo lama-25 ifumana i-14.2V{5}}zombini ngaphezulu kombane okhuselekileyo wokudada kweyona qondo lobushushu.

Iitshaja zebhetri ezisemgangathweni zibandakanya izinzwa zobushushu. Isivamvo soluvo sinokuba sangaphakathi (ukuba itshaja yabelana ngendawo evalekileyo kunye neebhetri) okanye ukude (iprobe ebekwe okanye kufutshane neebhetri). Isilawuli esincinci setshaja sihlengahlengisa amandla ombane wokuphuma ngokuzenzekelayo ngokusekelwe kufundo lobushushu.

Ubalo lwembuyekezo luqondile: Kwi-12V ekhokelayo -ibhetri ye-asidi eneeseli ezi-6 kunye nesiseko se-float ye-13.5V kwi-25 degree, sebenzisa -3.9mV/℃× 6 cells=-23.4mV/degree. Ukuba ubushushu bebhetri yi-30℃, lungisa i-voltage nge (30-25) × -0.0234V=-0.117 V, inika i-13.38V.

I-float yangoku ibonisa impilo yebhetri. Ibhetri esempilweni kwimowudi yokudada kufuneka izobe ngaphantsi kwe-1% yomlinganiselo we-Ah kwii-amps. Ukuphakama okuphezulu kwangoku kubonisa iingxaki: iibhulukhwe ezimfutshane zangaphakathi,{3}}iiseli ezomisiweyo kwiibhetri ezizaliswe ngamanzi, okanye i-sulfate esuka kwi-underchargeing yangaphambili.

Iisistim ezikwizinga eliphezulu zokujonga ibhetri zilandelela iintsingiselo zangoku ngokuhamba kwexesha. Ukonyuka kancinci kudla kwandulela ukusilela kwebhetri ngeenyanga, kunika isilumkiso sokucwangcisa ukutshintshwa ngexesha lolungiso lweefestile kunokuhlangabezana nokusilela okumangalisayo.

Imigibe emininzi ihlala ibetha iinkqubo zokutshaja ezidadayo. Ukusebenzisa itshaja eyenzelwe ikhemistri yebhetri enye nenye mhlawumbi yeyona ixhaphakileyo. Ibhetri yejeli kwitshaja yebhetri ephuphumayo efumana i-13.8V endaweni ye-13.2V efunekayo iya kutshisa ngokugqithisileyo kwaye ingaphumeleli kwangaphambi kwexesha.

Enye impazamo eyenzeka rhoqo kukutyeshela imbuyekezo yobushushu kwiindawo ezinotshintsho olukhulu lobushushu. Ibhanki yebhetri kwikhabhathi yefowuni yangaphandle inokufumana amaqondo obushushu ukusuka kwi-10℃ukuya kwi-50℃ngonyaka. Ngaphandle kwembuyekezo, iibhetri zihlawulwa ngokugqithisileyo ehlotyeni kwaye zitshajwa ngaphantsi ebusika, oko kunciphisa kakhulu ixesha lokuphila.

Ukuphoswa yinguqu ukusuka ekufunxeni ukuya edadayo nako kubangela iingxaki. Ezinye -iitshaja ezikumgangatho ophantsi azize zinciphise ngokwenene amandla ombane ukuya kumanqanaba afanelekileyo okudada, endaweni yoko zibambe iibhetri kumbane wokufunxa ngokungenasiphelo. Oku kusebenza iiyure okanye iintsuku kodwa kubangela ukonyuka komonakalo kwiiveki kunye neenyanga zoqhagamshelwano oluqhubekayo.
