Iibhetri zeLithium zitshaja ngokukhawuleza kakhulu kuneebhetri zelead ezitywiniweyo (SLA). Unokuzibuza ukuba kukhawuleza kangakanani kwaye kuthetha ntoni kuwe njengomsebenzisi wokugqibela. Ngaba itshaja ye-SLA eqhelekileyo ingasetyenziselwa ukuhlawula ibhetri ye-lithium?
Ukutshaja ukuFaka umahluko phakathi kwe-SLA kunye neLithium
Ukutshaja ibhetri ye-SLA kunokutya ixesha. Ngokomzekelo, i-12-volt, i-20-amp-hour deep cycle ye-SLA ibhetri ithatha malunga neeyure ze-6.5 ukufikelela kwintlawulo epheleleyo, ngelixa i-12.8-volt i-20-amp iyure ye-lithium iron phosphate ibhetri iphumelele intlawulo epheleleyo kwiiyure nje ze-2.5.
Umjikelo wokutshaja iibhetri ze-SLA unezigaba ezithathu: umbane oqhubekayo, umbane ongaguqukiyo, kunye nokutshaja okudadayo.
Kwinqanaba eliqhubekayo langoku, i-20Ah i-deep cycle ye-SLA ibhetri ifikelela kwi-80% ye-State of Charge (SOC). Inqanaba le-voltage rhoqo ligqiba i-20% eseleyo, ithatha malunga ne-50% yexesha elipheleleyo lokutshaja.
Okokugqibela, intlawulo ye-float iyagcinwa ukuthintela ukukhupha ngaphezulu kokuzikhupha.
Umjikelo wokutshaja we-lithium unezigaba ezibini: i-voltage eqhubekayo yangoku kunye neyokuhlala.
Kwinqanaba eliqhubekayo langoku, ibhetri ifikelela kwi-99% umthamo (i-SOC ye-99%) kwi-96% yexesha lokuhlawula. Ibhetri ye-lithium eyi-12.8V 20AH iphantse yatshaja ngokupheleleyo ngaphantsi kweyure ezimbini. Inqanaba le-voltage eqhubekayo yongeza nje i-1%, ithatha kuphela i-4% yexesha lokuhlawula.
Ukongeza, iibhetri ze-lithium azidingi ntlawulo yokudada ngenxa yezinga eliphantsi lokuzikhupha.
Ukufunxwa kweLithium kwiProfayili yokuTshaja ye-SLA
Xa uqwalasela ibhetri ye-lithium njengento yokulahla ibhetri ye-SLA kunye neshaja ye-SLA, kubalulekile ukuqonda imiphumo enokubakho.
Ukuhlawula ibhetri ye-lithium kwishaja ye-SLA kwi-13.8V ivumela ukuba ifikelele kwi-95% umthamo malunga ne-90% yexesha lokutshaja, ngelixa i-14.6V, ifikelela kwi-99% kwi-95% yexesha.
Ukuhlawula ibhetri ye-lithium kwiprofayili ye-SLA kwandisa ixesha malunga neeyure ze-2.5 (usebenzisa iprofayili ye-lithium) kwiiyure ze-5. Nangona kunjalo, njengoko kuboniswe kwitshathi engezantsi, ibhetri ye-lithium isahlawula ngokukhawuleza kunebhetri ye-SLA elinganayo kwiprofayili ye-SLA.
Ungasebenzisa iibhetri ze-lithium kwitshaja ye-SLA ukuba ayinayo imo ye-de-sulfation okanye iimpawu zokubona ibhetri efileyo. I-De-sulfation pulses inokonakalisa okanye ivale i-BMS yebhetri ye-lithium, kwaye ii-detectors zebhetri ezifileyo zinokuthi zitolike kakubi ibhetri ye-lithium ekhuselweyo njengefile.
Iitshaja ze-SLA ngokuqhelekileyo zisebenza kumbane phakathi kwe-13.8V kunye ne-14.7V, ivumela iibhetri ze-lithium ukuba zihlawule ngokukhawuleza kune-SLAs. Iibhetri zeLithium zifikelela kwintlawulo epheleleyo ngokukhawuleza kwaye zifikelele kumazinga aphezulu entlawulo phakathi kolu luhlu lwamandla ombane.
Ngaba iTshaja ye-SLA eqhelekileyo iLonakala ibhetri yeLithium?
Ukusebenzisa itshaja ye-SLA kwibhetri ye-lithium inokwamkeleka, ngakumbi ukuba ayinayo i-de-sulfate mode.
Kwizicelo zebhayisikili zemihla ngemihla, ukuthotywa akunakwenzeka, nangona ibhetri ye-lithium ingenakufikelela kumthamo opheleleyo (umzekelo, ibhetri ye-lithium ye-20AH ayinakufezekisa i-20 amps ngeshaja ye-SLA). Ukuba ayisetyenziswa rhoqo kwaye ishiywe kwi-float ixesha elide, kungcono ukukhupha ibhetri phambi kokugcinwa.
Iibhetri ze-lithium zisebenza ngokugqibeleleyo kwi-50% ye-state of charge (SOC). Ibhetri yeHolo incoma ukusebenzisa iitshaja ezifanelekileyo kwikhemistri yebhetri nganye kunye nokujonga iibhetri ze-lithium zombane ophantsi rhoqo kwiinyanga ezi-3-4.
