Ukugcinwa kwamandla kuye kwaba yinto eshushu kakhulu kunye neshishini, kwaye iibhetri ze-LiFePO4 ziye zaba yi-chemistry engundoqo yeenkqubo zokugcina amandla ngenxa yebhayisikili ephezulu, ubomi obude, ukuzinza okukhulu kunye neziqinisekiso eziluhlaza. Phakathi kweentlobo ezahlukeneyo zeiibhetri zeLiFePO4, iibhetri ze-48V kunye ne-51.2V zihlala zithelekiswa, ngokukodwa kwizicelo zokuhlala kunye nezorhwebo. Kweli nqaku, siza kuphonononga umahluko ophambili phakathi kwezi zimbini zokhetho lombane kwaye sikuhambe ngendlela yokukhetha ibhetri elungileyo kwiimfuno zakho ezithile.
Ukucacisa iVoltage yeBattery
Ngaphambi kokuba sixoxe ngomahluko phakathi kwe-48V kunye ne-51.2V ibhetri yeLiFePO4, masiqonde ukuba yintoni amandla ombane ebhetri. I-Voltage ngubungakanani obubonakalayo bomahluko onokwenzeka, obonisa ubungakanani bamandla anokubakho. Kwibhetri, i-voltage inquma ubungakanani bamandla ohamba ngawo ngoku. Umbane oqhelekileyo webhetri udla ngokuba yi-3.2V (umzekelo, iibhetri zeLiFePO4), kodwa ezinye iinkcukacha zombane ziyafumaneka.
Amandla ombane ebhetri yimetric ebaluleke kakhulu kwiinkqubo zokugcina amandla kwaye imisela ukuba angakanani amandla ibhetri yogcino enokubonelela kwisistim. Ukongezelela, ichaphazela ukuhambelana kwebhetri ye-LiFePO4 kunye namanye amacandelo kwinkqubo yokugcina amandla, njenge-inverter kunye nomlawuli wentlawulo.
Kwizicelo zokugcina amandla, uyilo lombane webhetri luchazwa rhoqo njenge-48V kunye ne-51.2V.
Uthini umahluko phakathi kwebhetri ye-48V kunye ne-51.2V yeLiFePO4?

Iimpawu zokukhutshwa zibhekisela ekusebenzeni kwebhetri xa ukhulula amandla agciniweyo kumthwalo, ochaphazela ngokuthe ngqo ukuzinza kunye nokusebenza kakuhle kwenkqubo yokusebenza. Iimpawu zokukhupha zichongwa yi-curve yokukhupha ibhetri, ubungakanani bokukhutshwa kwangoku kunye nokuqina kwebhetri:
Iiseli ze-51.2V ze-LiFePO4 zihlala zikwazi ukukhupha ngokuzinzileyo kwimisinga ephezulu ngenxa yombane ophezulu. I-voltage ephezulu ithetha ukuba iseli nganye inomthwalo omncinci wangoku, onciphisa umngcipheko wokutshisa kunye nokukhutshwa ngokugqithiseleyo. Olu phawu lwenza ukuba iibhetri ze-51.2V zilunge ngakumbi kwiinkqubo ezifuna ukuphuma kwamandla aphezulu kunye nokusebenza okuzinzile ixesha elide, njengokugcinwa kwamandla orhwebo, izixhobo zoshishino, okanye izixhobo zombane ezilambele umbane.
3. Imveliso yamandla
Ukukhutshwa kwamandla ngumlinganiselo wexabiso lilonke lamandla ibhetri enokubonelela ngayo kumthwalo okanye inkqubo yombane ngexesha elithile, elichaphazela ngokuthe ngqo amandla akhoyo kunye noluhlu lwenkqubo. Ubuninzi bombane kunye nokuxinana kwamandla ebhetri zizinto ezimbini eziphambili ezichaphazela ukuphuma kwamandla.
Iibhetri ze-51.2V LiFePO4 zibonelela ngemveliso yamandla ephezulu kuneebhetri ze-48V LiFePO4, ngokukodwa ekubunjweni kwemodyuli yebhetri, iibhetri ze-51.2V zineseli eyongezelelweyo, oku kuthetha ukuba unokugcina umthamo omncinci, umzekelo:
48V 100Ah lithium iron phosphate ibhetri, umthamo wokugcina = 48V * 100AH = 4.8kWh
51.2V 100Ah lithium iron phosphate ibhetri, umthamo wokugcina = 51.2V * 100Ah = 5.12kWh
Nangona imveliso yamandla yebhetri enye ye-51.2V i-0.32kWh kuphela ngaphezu kwebhetri ye-48V, kodwa ukuguqulwa komgangatho kuya kubangela utshintsho lobungakanani, iibhetri ze-10 51.2V ziya kuba yi-3.2kWh ngaphezu kwebhetri ye-48V; 100 51.2V iibhetri ziya kuba ngama-32kWh ngaphezu kwebhetri ye-48V.
Ngoko ke kumbane ofanayo, ukuphakama kwamandla ombane, amandla amaninzi aphuma kwinkqubo. Oku kuthetha ukuba iibhetri ze-51.2V ziyakwazi ukubonelela ngenkxaso yamandla amaninzi ngexesha elifutshane, elilungele ixesha elide, kwaye linokwanelisa imfuno enkulu yamandla. Iibhetri ze-48V, nangona amandla abo aphuma kancinci, kodwa anele ukujamelana nokusetyenziswa kwemithwalo yemihla ngemihla endlwini.
Ukuhambelana kweNkqubo
Ingaba ibhetri ye-48V Li-FePO4 okanye ibhetri ye-51.2V Li-FePO4, ukuhambelana ne-inverter kufuneka kuthathelwe ingqalelo xa ukhetha inkqubo epheleleyo yelanga.
Ngokuqhelekileyo, iinkcukacha zee-inverters kunye nabalawuli bentlawulo bahlala bedwelisa uluhlu oluthile lombane webhetri. Ukuba inkqubo yakho yenzelwe i-48V, ngoko zombini i-48V kunye ne-51.2V iibhetri ziya kusebenza ngokubanzi, kodwa ukusebenza kunokwahluka ngokuxhomekeke kwindlela amandla ombane ebhetri ahambelana ngayo nenkqubo.
Uninzi lweeseli zelanga ze-BSLBATT ziyi-51.2V, kodwa ziyahambelana nazo zonke ii-48V off-grid okanye i-hybrid inverters kwimarike.
Ixabiso kunye nokusebenza kakuhle kweendleko
Ngokweendleko, iibhetri ze-51.2V ngokuqinisekileyo zibiza kakhulu kuneebhetri ze-48V, kodwa kwiminyaka yakutshanje, umehluko wexabiso phakathi kwezi zibini zincinci kakhulu ngenxa yokunciphisa iindleko ze-lithium iron phosphate materials.
Nangona kunjalo, ngenxa yokuba i-51.2V inemveliso engaphezulu kunye nomthamo wokugcina, iibhetri ze-51.2V ziya kuba nexesha elifutshane lokubuyisela ixesha elide.
Iindlela ezizayo kwitekhnoloji yebhetri
Ngenxa yeenzuzo ezizodwa ze-Li-FePO4, i-48V kunye ne-51.2V iya kuqhubeka idlala indima ebalulekileyo kwixesha elizayo lokugcinwa kwamandla, ngakumbi njengoko imfuno yokuhlanganiswa kwamandla ahlaziyekayo kunye nezisombululo zamandla angaphandle kwegridi zikhula.
Kodwa iibhetri zamandla ombane aphezulu ngokusebenza okuphuculweyo, ukhuseleko kunye noxinaniso lwamandla kusenokwenzeka ukuba ziqheleke ngakumbi, ziqhutywa yimfuno yezisombululo ezinamandla ngakumbi kunye nezinokwehla kwamandla ombane. Kwi-BSLBATT, umzekelo, siqalise uluhlu olupheleleyo lweiibhetri eziphezulu(umbane wenkqubo ongaphezulu kwe-100V) kwindawo yokuhlala kunye neyorhwebo/usetyenziso logcino lwamandla oshishino.
