Ukuba uyakha i inkqubo yamandla engaphandle kwegridi, mhlawumbi uya kusebenzisa iibhetri zeLiFePO4. Ezi bhetri zikhuselekile kwaye zihlala ixesha elide kuneebhetri ze-asidi ezindala.
Nangona kunjalo, basebenza ngokwahlukileyo. Awukwazi ukuqikelela ukuba ibhetri izele kangakanani ngokujonga nje amandla ombane. Kufuneka kwakhona ucwangcise izixhobo zakho ngamanani achanekileyo. Ukuba usebenzisa useto olungalunganga, ungonakalisa ibhetri.
Esi sikhokelo sibonelela ngeetshathi ezilula kunye namanani owadingayo ukuseta inkqubo yakho.
Izinto ezisisiseko malunga ne-LiFePO4 yeBattery Voltage
Ukuqonda ibhetri yakho, yazi ukuba a “iseli” yiyunithi yayo esisiseko. Ibhetri ineeseli ezininzi eziqhagamshelweyo.
Iseli nganye ye-LiFePO4 ine-voltage ebizwa ngokuba yi-3.2V, eyi-voltage ephakathi ngexesha lokusetyenziswa. Uluhlu lwayo olukhuselekileyo luyi-2.5V ukuya kwi-3.65V.
Iibhetri ze-LiFePO4 zine-flat discharge curve, ngoko ke amandla ombane ahlala eqinile ngexesha lokusetyenziswa, ngokungafaniyo neebhetri zemoto apho umbane wehla ngokuthe ngcembe. Oku kusebenza kakuhle kwenza kube nzima ukulinganisa amandla aseleyo.
Itshathi yeVoltage yeLiFePO4: 12V, 24V, kunye ne48V
Ezi tshathi zilandelayo zibonisa i-Resting Voltage, elinganiswa xa ibhetri ingatshaji kwaye ingenazixhobo zamandla. Linda imizuzu engama-30 ubuncinane emva kokusetyenziswa phambi kokuba ujonge eli nani.

Iibhetri ze-LiFePO4 eziManinzi, ziNtaphe, kwaye ziLinganise iiVoltages
Uya kuyibona le migaqo kwiisetingi zesixhobo sakho. Nantsi into abayithethayo kwaye ngawaphi amanani okusetyenziswa.
I-Bulk Voltage (Absorption): Lo ngumbane osetyenziselwa ukutshaja ibhetri ukusuka engenanto ukuya kwizele. Ngowona mbane uphezulu itshaja iya kufika kuwo.
- Inkqubo ye-12V: 14.2V ukuya ku-14.6V
- Inkqubo ye-24V: 28.4V ukuba 29.2V
- Inkqubo ye-48V: 56.8V ukuba 58.4V
I-Float Voltage: Yakube igcwele ibhetri, itshaja iyawawisa amandla ombane. Oku kugcina intlawulo ngaphandle koxinzelelo lweeseli.
- Inkqubo ye-12V: 13.5V ukuya kwi-13.6V
- Inkqubo ye-24V: 27.0V ukuya kwi-27.2V
- Inkqubo ye-48V: 54.0V ukuya kwi-54.4V
Linganisa i-Voltage: Ukulinganisa yi-overcharge elawulwayo esetyenziselwa iibhetri ze-lead-acid ukucoca iipleyiti.
- Ukuseta: KUVALIWE okanye kuvaliwe.
- Isilumkiso: Musa ukusebenzisa ukulingana kwiibhetri zeLiFePO4. Ibangela amandla ombane aphezulu anokonakalisa ngokusisigxina iiseli ze-lithium.
Iibhetri zeLiFePO4: Iinkqubo zokuTshaja kunye nokuZikhupha
Ukuziphatha kwebhetri kuyatshintsha kuxhomekeke ekubeni amandla ayangena okanye ayaphuma.
Inkqubo yokuTjaja
Xa uhlawula ibhetri, i-voltage iyanyuka.
Itshaja ibeka ngokuqhubekayo yangoku de i-voltage ibethe i-Bulk setting (efana ne-14.4V). Emva koko, yangoku iyehla njengoko ibhetri ifunxa isuntswana lamandla lokugqibela.
Inkqubo yokukhupha
Xa usebenzisa ibhetri, amandla ombane ayancipha.
- Igcwele: Iqala phezulu (malunga ne-13.6V okanye ngaphezulu).
- Ephakathi: Yehla ngokukhawuleza ukuya malunga ne-13.3V kwaye ihlala khona imini yonke. Le yindawo ethe tyaba yegophe.
- Akunanto: Nje ukuba ibethe malunga ne-12.9V, iya isiba phantsi. Ngaphantsi kwe-12.8V, i-voltage iya kuhla ngokukhawuleza. Oku kubizwa ngokuba yi “iliwa.”
Ngaba iVoltage ichaphazela ukusebenza kwebhetri yeLiFePO4?
Ewe, amandla ombane achaphazela indlela esebenza ngayo inkqubo yakho.
- Umthamo: I-voltage kunye nomthamo zinxulumene ngokuthe ngqo – amandla ombane aphezulu anyusa umthamo, okuvumela ibhetri ukuba igcine amandla amaninzi kunye nezixhobo zamandla ixesha elide.
- Ubomi: Iibhetri ze-LiFePO4 eziphezulu zihlala ixesha elide kwaye ziyakwazi ukusingatha imijikelezo emininzi. Ukugcina amandla ombane afanelekileyo kuthintela ukubaleka kwe-thermal, ukuphendula kweekhemikhali okungaphelelanga, kunye nokwehla.
- Ukutshaja: Umbane webhetri uchaphazela ukhuseleko lokutshaja kunye nokusebenza kakuhle. Umbane ongafanelekanga ubangela ukushisa okugqithisileyo okanye ukutshajiswa ngaphantsi, ukonakalisa ukusebenza, impilo, kunye nobomi.
- Ukukhupha: Ukukhupha amandla ombane angaphantsi kwesicetyiswayo kuyonakalisa ngokusisigxina ibhetri kwaye kunciphisa ubomi bayo.
- Ukusebenza kakuhle: Amandla ombane aphezulu aphucula ukusebenza kakuhle kokunikezelwa kwamandla.
Ujongwa njani ubungakanani bebhetri yeLiFePO4
Ukusebenzisa i-voltmeter ukujonga ukuba ibhetri igcwele kangakanani na akusebenzi kakuhle.
Ngenxa yokuba i-voltage curve is flat, umahluko phakathi kwebhetri kwi-40% epheleleyo kunye ne-70% egcweleyo incinci kakhulu. Inokuba yi-0.1 volts kuphela. Ii-voltmeters ezishibhile azichanekanga ngokwaneleyo ukuba zifunde lo mahluko.
Isisombululo kufuneka usisebenzise a I-Smart Shunt.
- I-Smart Shunt sisixhobo esifakwe kwintambo yebhetri engalunganga.
- Ibala yonke i-amp yamandla engena ebhetri.
- Ibala yonke i-amp eshiya ibhetri.
- Ibala ipesenti echanekileyo (iState of Charge) kwaye ibonise kwiscreen okanye kwifowuni yakho.
Ukuqukumbela
Iibhetri zeLiFePO4 zigqwesile kubomi obungaphandle kwegridi, kodwa zifuna ingqalelo kwiinkcukacha.
- Khumbula amandla ombane aqhelekileyo: 3.2V ngeseli nganye.
- Cwangcisa itshaja yakho: Sebenzisa iBulk kunye neenombolo zeFloat ezidweliswe ngasentla.
- Khubaza ukulingana: Oku kukhusela ibhetri yakho kumonakalo.
- Ungayihoyi i-voltage yokuhlolwa kwemihla ngemihla: Sebenzisa i-Smart Shunt ukwazi ngokuthe ngqo ukuba angakanani amandla aseleyo.
FAQ
Kutheni ibhetri yam ifunda i-13.3V emva kokuba ndiyihlawulise kwi-14.6V?
Oku kuqhelekile. 14. I-6V yi-voltage yokutshaja, kwaye ibhetri ibuyela kumbane wayo wokuphumla emva kokutshaja. I-voltage yokuphumla ye-13. I-6V ithetha ukuba ihlawuliswe ngokupheleleyo, kodwa yehla ukuya kwi-13. 3V ngokusetyenziswa okuncinci.
Ndingayisebenzisa Itshaja eneasidi yeLead?
Yisebenzise kuphela ukuba unokukhubaza ifayile “desulfation” okanye “ukulinganisa” indlela. Ukuba itshaja idlula i-14. 6V, iya konakalisa ibhetri yakho ye-lithium eyi-12V. Ukusebenzisa itshaja eyenzelwe i-lithium kukhuselekile.
Ngawaphi amandla ombane ekumele ndiwuqhawule kuMthwalo wam?
Kwinkqubo ye-12V, yeka ukusebenzisa ibhetri kwi-12. 0V ukugcina amandla athile. Ukuyikhupha ukuya kwi-10. I-0V ibangela ukucinywa kwe-BMS, mhlawumbi ifuna itshaja ekhethekileyo ukuqalisa kwakhona ibhetri.
