Ukuthathwa okungundoqo:
- I-Voltage ibalulekile kuyilo lwebhetri yesiqhelo, ichaphazela ukuphuma kwamandla kunye nokuhambelana kwesixhobo. Qonda i-voltages yegama, ehlawuliswayo, kunye neyokukhutshwayo, kwaye uqwalasele ikhemistri yebhetri, iimfuno zesicelo, kunye nemimiselo yokuthumela.
Ukuyila a ipakethi yebhetri yesiko kufana nokudibanisa iphazili entsonkothileyo. Kufuneka ucinge malunga neenkcukacha zamandla, okwangoku, umthamo, iimfuno zobungakanani, ulungelelwaniso lweseli, kunye nenani leeseli. Kodwa kukho enye into ebalulekileyo ehlala ingahoywa: i-voltage. Ke masingene kwihlabathi lombane lombane webhetri kwaye siqonde ukubaluleka kwayo.
Yintoni iVoltage kwaye kutheni ibalulekile?
Umbane ufana noxinzelelo lwamanzi kumbhobho wegadi yakho. Ityhala umbane kwizixhobo zakho. Ukuphakama kwamandla ombane, kokukhona amandla angakumbi anokusebenzisa izixhobo zakho.
I-Voltge ephantsi vs iMveliso yoMbane oPhezulu
Izixhobo zineemfuno zamandla ezahlukeneyo. Imveliso ye-low-voltage ayifuni amandla amaninzi okuqhuba, ngoko ke ipakethe yebhetri idinga kuphela ukukhupha inani elincinci langoku. Umva, iimveliso ezinamandla kakhulu zifuna amandla amaninzi okuqhuba, ngoko zidinga ipakethe yebhetri enokuthi ikhuphe uninzi lwangoku.
Ukucacisa iVoltage yeBattery
Ukuqonda amandla ombane wepakethi yebhetri, kufuneka sijonge izinto ezintathu:
1. Umbane oqhelekileyo
2. Umbane xa ugcwaliswe ngokupheleleyo
3. I-voltage xa ikhutshwe ngokupheleleyo
Makhe sihlolisise le migaqo.
Umbane woMbane
Esi sisiphumo sombane esikhutshwa yiseli xa sihlawulwe. Kufana nomndilili wesantya semoto kuhambo olude.
IVoltage eCharge ngokupheleleyo
Le yeyona ndlela yombane iphezulu enokufikelela kuyo ibhetri xa igcwaliswe ngokupheleleyo. Kufana nesantya esiphezulu imoto yakho enokufikelela kuyo kwindlela ethe tye.
I-Voltage ekhutshwe ngokupheleleyo
Eli lelona nqanaba lombane lisezantsi ibhetri enokufikelela kulo ngaphambi kokuba liqwalaselwe “engenanto”. Kufana nesona santya sicothayo imoto yakho inokuhamba ngaphambi kokuba iyeke ukuhamba.
I-Voltage yi-Battery Chemistry
Kanye njengokuba iimoto ezahlukeneyo zinezantya ezahlukeneyo, iibhetri ezahlukeneyo zineevolthi ezahlukeneyo. Nantsi imilinganiselo yombane yezinye iikhemistri zebhetri eziqhelekileyo:
1. I-NiCad: 1.2 volts
2. I-NiMH: 1.4 volts
3. I-Lithium-ion: 3.6 volts
4. I-lead-acid: 2 volts
Khumbula, ezi zizinto kuphela “isantya esiphakathi” – imveliso yokwenyani inokwahluka.
Iibhetri ze-NiMH zine-voltage ye-1.2V, kodwa zinokubonelela ukuya kuthi ga kwi-1.4V xa zihlawulwe ngokupheleleyo. Iibhetri ze-NiCad kunye ne-NiMH zombini zine-voltage egcwele ngokupheleleyo ye-1.4V. Iibhetri ze-lead-acid zine-voltage egcweleyo ye-2.1V, ngelixa iibhetri ze-lithium-ion zine-voltage egcweleyo ye-4.2V.
Iibhetri ze-NiCad kunye ne-NiMH zinokukhupha ngokupheleleyo kwi-1.0V, ngelixa iibhetri ze-lead-acid zikhupha kwi-1.75V. Iibhetri ze-lithium-ion akufanele zikhutshwe ngokupheleleyo, njengoko oku kungonakalisa. Isici esisikiweyo sokhuseleko siqinisekisa ukuba iibhetri ze-lithium-ion azize zihambe ngaphantsi kwe-2.8V ukuya kwi-3.0V.
Ukumisela iVoltage yeSicelo
Ukumisela amandla ombane osetyenziswayo kufana nokulinganisa i-seesaw. Ukuchasana kwesicelo kufana nobunzima kwelinye icala le-seesaw, kwaye okwangoku kufana nobunzima kwelinye icala. Inxaki ilula:
Umbane (V) = Okwangoku (I) x Ukuchasa (R)
Ukusebenzisa imitha yangoku kunye nomthombo wamandla oguquguqukayo kunokunceda ekumiseleni umzobo okhoyo wenkqubo. Olu lungelelwaniso lunokusetyenziselwa ukuqinisekiswa kokubini obona mbane uphezulu kunye nobuncinci bombane obufunekayo kwinkqubo yakho. Kubalulekile ukurekhoda ufundo lwangoku. Injongo yakho kufuneka ibe kukufumana ixabiso eliwela phakathi kwale milinganiso mibini, eliya kumela indawo yokusetyenziswa kwamandla amancinci.
Ukuqonda i-voltage spectrum ngale ndlela kubalulekile kwiimveliso kunye nezicelo ezinokuxhomekeka kumbane oguquguqukayo. Ngokuchaseneyo, ezinye iimveliso kunye nezicelo ziya kubonisa ukusetyenziswa kwamandla okuzinzileyo.
IiRange zombane
Yonke imveliso inoluhlu oluthile lwamandla ombane olunokusingatha phambi kokuba iqalise ukungasebenzi kakuhle. Kufana nesantya esamkelekileyo semoto. Ukuba uhamba ngokucotha kakhulu, injini inokuma. Ukuba uhamba ngokukhawuleza kakhulu, inokutshisa kakhulu.
Umthamo weSeli kunye neVoltage
Enye into ebalulekileyo kumthamo weeseli. Oku kumisela ukuba imveliso yakho inokusebenza ixesha elingakanani phambi kokutshaja ibhetri. Yithathe njengobungakanani betanki yegesi yemoto yakho. Umthamo omkhulu weseli uthetha ukuba imveliso yakho inokusebenza ixesha elide ngentlawulo enye. Umthamo weseli encinci uthetha ukuba kuya kufuneka uyitshaje imveliso yakho rhoqo.
Unyino lokuthumela ngokuSekwe kwiVoltage
Ukuthumela izixhobo eziphezulu ze-voltage, ngakumbi ezo zineebhetri ezisekelwe kwi-lithium, zifuna ukunakekelwa okukhethekileyo ngenxa yokungazinzi kwabo. Kufana nokuthutha iikhemikhali eziguquguqukayo – kufuneka ulandele imithetho engqongqo yokhuseleko efana KUNYE 38.3.
Ngokwezikhokelo ezibekwe yi IATA, iibhetri ezisekelwe kwi-lithium zinokuthuthwa ngokuzimeleyo okanye ngaphakathi kwezixhobo. Ukuba zithuthwa ngokuzimeleyo, imeko yabo yentlawulo (SoC) mayingagqithi kwi-30%.
Ngaphezu koko, ubuninzi beeseli okanye iibhetri ezinokuthuthwa ngaxeshanye zichongwa ngumlinganiselo wensimbi ye-lithium equlethwe ngaphakathi kwebhetri, nokuba ngaba zithuthwa ngaphakathi kwesixhobo, ngokuzimeleyo, okanye kunye nezixhobo. Ezinye iipakethi zinokufuna uphawu oluthile ukubonisa ubukho bebhetri ye-lithium ngaphakathi kwesikhongozeli.
IBettery Pack Voltage yoYilo lweMveliso
Ukwenza ipakethi yebhetri yemveliso yakho, kuya kufuneka uqwalasele izinto ezahlukeneyo, kubandakanya amandla ombane, ikhemistri, ulungiselelo lweeseli, kunye nobungakanani bebhetri. Injongo kukudala ibhetri enika amandla afanelekileyo ngelixa ifanelekile ngaphakathi kwemiqobo yoyilo lwemveliso.
Ngokomzekelo, ipakethe ye-10 yeeseli zebhetri ye-NiMH inokubonelela nge-volts ye-14 yamandla ngelixa igcina iindleko eziphantsi. Nangona kunjalo, njengoko iiseli ezininzi zongezwa, ipakethe iya kuba nzima kwaye ibe nzima. Isisombululo esikhaphukhaphu ngakumbi kukusebenzisa iibhetri ezisekwe kwi-lithium ezineseli ezimbalwa. Ngendlela, ezi bhetri kufuneka zibe neenkqubo ezongezelelweyo zesatifikethi sothutho kunye nezithintelo, ezinokunyusa iindleko.
Ukuqukumbela
Ukusebenzisana no umenzi wepakethi yebhetri eqeqeshiweyo kwangethuba kwinkqubo yoyilo inokuba luncedo olukhulu xa ufumanisa amandla ombane afunekayo. Kwibhetri yeHolo, sinokukunceda uqikelele uyilo lwendawo evalelweyo yebhetri ukuqinisekisa ukuba kukho indawo eyaneleyo yepakethe. Ngolu yilo, unokuvavanya ukusebenza kwemveliso yakho kwaye wenze naluphi na uhlengahlengiso oluyimfuneko.
