Okwangoku kwiimarike, ezininzi iimveliso zisebenzisa iibhetri ze-lithium kwisikhululo samandla esiphathwayo.Kwaye kukho iikhemistri eziphambili zebhetri, i-Nickel Manganese Cobalt (NMC) kunye ne-lithium iron phosphate (LFP).
Ngokomzekelo, sinokufumanisa ukuba i-LFP ye-EcoFlow river 2 pro, indlu yamandla ye-Anker 555 kunye ne-Bluetti AC200P, i-NMC ye-Goalzero YETI1500X kunye ne-EcoFlow DELTA mini.Ngendlela, andikwazi ukuxelela ukuba yeyiphi i-chemistry yeemveliso zeJackery kuba ithi nje Lithium-ion.
Ngoko ke nanku umbuzo, Yeyiphi ikhemistri yebhetri onokuyikhetha xa uthenga isikhululo samandla esiphathwayo?
Phambi kokuba siphendule lo mbuzo, kufuneka kuqala sifumane iimpawu zekhemikhali zezi ntlobo zimbini zeebhetri kwaye senze ukhetho lokuthenga olusekelwe kwiimfuno zethu zokwenyani.Siza kuthelekisa ezi zimbini kwimiba emithathu: ukuxinana kwamandla, ukhuseleko, kunye nobomi bomjikelezo.
Ngoko ke umahluko wokuqala kukuxinana kwamandla, ndiya kusebenzisa iGrwatt njengomzekelo wokubonisa.Ezi nkcukacha zithathwe kwiwebhusayithi yakwaGrwatt.Ngomlinganiselo ofanayo, i-NMC esekelwe kwi-1500 inomthamo we-1512wh, kwaye inobunzima be-33 pounds, kunye ne-LFP esekelwe kwi-1300 umthamo we-1382wh kodwa inobunzima be-42 pounds.Ke, ngokwesiqhelo iibhetri ze-NMC zinoxinzelelo olukhulu lwamandla xa kuthelekiswa neebhetri ze-LFP.Oku kuthetha ukuba banokugcina amandla amaninzi ngeyunithi nganye ubunzima okanye umthamo, okukhokelela kubomi obude bebhetri kunye nemveliso yamandla ephezulu.
Iimodeli zeGROWATT
Umahluko wesibini lukhuseleko.Iibhetri ze-NMC ngokubanzi zineempawu zokhuseleko ezilungileyo, kodwa ziqhelene kakhulu nokubaleka kwe-thermal kunye neengozi zomlilo ezinokubakho, ngakumbi xa zisesichengeni sobushushu obuphezulu okanye umonakalo womzimba.Abavelisi babandakanya iindlela ezahlukeneyo zokhuseleko ukunciphisa le mingcipheko, efana neenkqubo zolawulo lweebhetri ezikumgangatho ophezulu (BMS).
Iibhetri ze-LFP zithathwa njengekhuselekile kuneebhetri ze-ternary lithium.Banozinzo oluphezulu lwe-thermal kwaye abanako ukutshisa kakhulu okanye ukubamba umlilo.I-iron phosphate inotyekelo olusezantsi lokubola kumaqondo obushushu aphezulu, inegalelo kwinkangeleko yokhuseleko iyonke yebhetri.
Ke kwisikhululo samandla esiphathwayo, iibhetri ze-NMC kunye ne-LFP azikho mahluko mkhulu kukhuseleko ngenxa ye-BMS ephezulu.
Umahluko wokugqibela ophambili bubomi bomjikelo.Jonga le fomu, ndidwelise iimodeli ezininzi ezidumileyo kunye neeparamitha zeGenki, uya kufumanisa ukuba iimodeli ze-LFP ezifana neGenki zilinganiswe kwimijikelo ye-3000 ukuya kuthi ga kwi-80% umthamo, kunye neemodeli ze-NMC ziyi-500 imijikelo.Umjikelo uthetha ukuba iqala kwi-100 ukuya ku-0, umva ukuya kwi-100%, ngumjikelo omnye.Ke ukuba uyenzile loo nto yonke imihla, ungasebenzisa iimveliso ezisekelwe kwi-LFP ngaphezulu kweminyaka eyi-9.Uza kufumana phantse amaxesha ama-6 ubude kunezikhululo zamandla ezise-NMC.
Uthelekiso lweParameter
Ngoko ke, isishwankathelo, iibhetri ze-NMC zinoxinano lwamandla oluphezulu kune-LFP, kwaye iibhetri ze-LFP zinobomi obude kune-NMC, kwaye zombini zinokusebenza okugqwesileyo kokhuseleko ngenxa yenkqubo yolawulo lwebhetri.
Emva kombuzo, Yeyiphi ikhemistri yebhetri onokuyikhetha xa uthenga isikhululo samandla esiphathwayo?NMC okanye LFP?Khetha iimveliso ezifanelekileyo kuwe ngokusekelwe kwiimfuno zakho zangempela kunye nohlahlo lwabiwo-mali.
