Njengamanje emakethe, izinhlobo eziningi zisebenzisa amabhethri e-lithium esiteshini samandla esiphathwayo.Futhi kukhona amakhemikhali amabili amakhulu ebhethri, i-Nickel Manganese Cobalt (NMC) kanye ne-lithium iron phosphate (LFP).
Isibonelo, singathola ukuthi i-LFP ye-EcoFlow river 2 pro, i-Anker power house 555 ne-Bluetti AC200P, i-NMC ye-Goalzero YETI1500X kanye ne-EcoFlow DELTA mini.Ngendlela, angikwazi ukusho ukuthi iyiphi i-chemistry yemikhiqizo kaJackery ngoba ivele ithi Lithium-ion.
Ngakho nawu umbuzo, Iyiphi ikhemikhali yebhethri ongayikhetha lapho uthenga isiteshi samandla esiphathwayo?
Ngaphambi kokuba siphendule lo mbuzo, sidinga kuqala ukuthola izici zamakhemikhali zalezi zinhlobo ezimbili zamabhethri futhi senze ukukhetha kokuthenga ngokusekelwe ezidingweni zethu zangempela.Sizoqhathanisa lezi zici ezimbili ezicini ezintathu: ukuminyana kwamandla, ukuphepha, nempilo yomjikelezo.
Ngakho umehluko wokuqala ukuminyana kwamandla, ngizosebenzisa i-Grwatt njengesibonelo ukuze ngibonise.Le mininingwane ithathwe kuwebhusayithi yakwaGrwatt.Ngobukhulu obufanayo, i-NMC esekelwe ku-1500 inomthamo we-1512wh, futhi inesisindo esingamaphawundi angama-33, kanti umthamo we-LFP osuselwe ku-1300 ngu-1382wh kodwa unesisindo esingamaphawundi angama-42.Ngakho-ke, ngokuvamile amabhethri e-NMC anomthamo omkhulu wamandla uma kuqhathaniswa namabhethri e-LFP.Lokhu kusho ukuthi bangagcina amandla engeziwe ngeyunithi ngayinye yesisindo noma ivolumu, okuholela empilweni ende yebhethri nokuphuma kwamandla aphezulu.
Amamodeli we-GROWATT
Umehluko wesibili ukuphepha.Amabhethri e-NMC ngokuvamile anezici ezinhle zokuphepha, kodwa athambekele kakhulu ekubalekeni okushisayo kanye nezingozi zomlilo ezingaba khona, ikakhulukazi uma evezwe kumazinga okushisa aphezulu noma ukulimala ngokomzimba.Abakhiqizi bahlanganisa izindlela zokuphepha ezehlukene ukuze banciphise lezi zingozi, njengezinhlelo zokuphatha ibhethri ezithuthukisiwe(BMS).
Amabhethri e-LFP athathwa njengephephile kunamabhethri e-ternary lithium.Zinokuqina okushisayo okuphezulu futhi mancane amathuba okuthi zishise kakhulu noma zibambe umlilo.I-iron phosphate inokuthambekela okuphansi kokubola emazingeni okushisa aphezulu, okunomthelela kuphrofayili yokuphepha iyonke yebhethri.
Ngakho esiteshini samandla esiphathwayo, amabhethri e-NMC ne-LFP awawona umehluko omkhulu ekuphepheni ngenxa ye-BMS ethuthukisiwe.
Umehluko wokugcina omkhulu impilo yomjikelezo.Bheka leli fomu, ngibhale amamodeli amaningana adumile kanye nemingcele yeGenki, uzothola ukuthi amamodeli e-LFP afana neGenki akalwe imijikelezo engu-3000 phansi aze afike kumthamo we-80%, futhi amamodeli e-NMC ayimijikelezo engama-500.Umjikelezo usho ukuthi uqala ku-100 uye ku-0, uhlehle ufike ku-100%, lowo umjikelezo owodwa.Ngakho-ke uma wenze lokho nsuku zonke, ungasebenzisa imikhiqizo esekwe ku-LFP ngaphezu kweminyaka eyi-9.Uzothola cishe izikhathi eziyisi-6 ubude kuneziteshi zikagesi ezisekelwe ku-NMC.
Ukuqhathaniswa kwepharamitha
Ngakho-ke ngokufingqiwe, amabhethri e-NMC anokuminyana kwamandla aphezulu kune-LFP, futhi amabhethri e-LFP anobude bokuphila okude kune-NMC, futhi womabili anokusebenza kokuphepha okuhle kakhulu ngenxa yesistimu yokuphatha ibhethri yentuthuko.
Emuva embuzweni othi, Iyiphi ikhemikhali yebhethri ongayikhetha lapho uthenga isiteshi samandla esiphathwayo?I-NMC noma i-LFP?Khetha imikhiqizo ekufanele ngokusekelwe ezidingweni zakho zangempela kanye nesabelomali senani.
