Ukwenyuka kwamanani entengo yamandla e-Europe akuholelanga nje ekukhuleni kwemakethe ye-PV ephezu kophahla, kodwa futhi kuqhubekisele phambili ukukhula okukhulu kwezinhlelo zokugcina amandla ebhethri lasekhaya.Umbiko weI-European Market Outlook yeSitoreji Sebhethri Sendawo yokuhlala2022-2026enyatheliswa yi-SolarPower Europe (SPE) ithola ukuthi ngo-2021, cishe amasistimu okugcina amandla amabhethri angu-250,000 afakwe ukuze asekele amasistimu wamandla elanga ahlala e-Europe.Imakethe yaseYurophu yokugcina amandla ebhethri yasekhaya ngo-2021 yafinyelela ku-2.3GWh.Phakathi kwalokho, iJalimane inesabelo semakethe esikhulu kunazo zonke, esibalelwa ku-59%, futhi umthamo omusha wokugcina amandla ngu-1.3GWh ngezinga lokukhula lonyaka lama-81%.
Kulindeleke ukuthi ekupheleni kuka-2026, umthamo ofakiwe wezinhlelo zokugcina amandla ekhaya uzokhuphuka ngaphezu kuka-300% ukuze ufinyelele ku-32.2GWh, futhi inani lemindeni enezinhlelo zokugcina amandla e-PV lizofinyelela ezigidini ezingu-3.9.
Kusistimu yokugcina amandla ekhaya, ibhethri yokulondoloza amandla ingenye yezingxenye ezibalulekile.Njengamanje, amabhethri e-lithium-ion athatha isikhundla semakethe esibaluleke kakhulu emkhakheni wamabhethri okugcina amandla asekhaya ngenxa yezici zawo ezibalulekile njengosayizi omncane, isisindo esilula kanye nempilo ende yenkonzo.
Ohlelweni lwamanje lwebhethri ye-lithium-ion ethuthukisiwe, ihlukaniswe ngebhethri ye-lithium ye-ternary, ibhethri ye-lithium manganate nebhethri ye-lithium iron phosphate ngokusho kwe-electrode material eqondile.Uma kucatshangelwa ukusebenza kokuphepha, impilo yomjikelezo kanye neminye imingcele yokusebenza, amabhethri e-lithium iron phosphate njengamanje ahamba phambili kumabhethri okugcina amandla asekhaya.Emabhethri e-lithium iron phosphate yasendlini, izici eziyinhloko zifaka okulandelayo:
- gukusebenza kahle kokuphepha.Esimeni sokusetshenziswa kwebhethri yesitoreji samandla sasekhaya, ukusebenza kokuphepha kubaluleke kakhulu.Uma kuqhathaniswa nebhethri ye-lithium ye-ternary, i-lithium iron phosphate yebhethri elinganiselwe iphansi, ingu-3.2V kuphela, kuyilapho izinga lokushisa elishisayo lokubola kwempahla liphezulu kakhulu kuno-200℃ webhethri le-ternary lithium, ngakho-ke kukhombisa ukusebenza okuhle kokuphepha.Ngaso leso sikhathi, ngokuthuthukiswa okuqhubekayo kobuchwepheshe bokuklama iphakethe lebhethri nobuchwepheshe bokuphatha ibhethri, kunolwazi oluningi kanye nobuchwepheshe bokusebenza obusebenzayo bokuphatha ngokugcwele amabhethri e-lithium iron phosphate, okukhuthaze ukusetshenziswa okubanzi kwamabhethri e-lithium iron phosphate insimu yokugcina amandla ekhaya.
- aokunye okuhle kumabhethri e-lead-acid.Esikhathini eside esidlule, amabhethri emkhakheni wokugcinwa kwamandla kanye nokunikezwa kwamandla okusekelayo kwakungamabhethri ane-asidi yomthofu, futhi amasistimu okulawula ahambisanayo aklanywa ngokubhekiselwa kububanzi bamandla kagesi wamabhethri e-lead-acid futhi asebenza emazweni ngamazwe nasekhaya. amazinga,.Kuwo wonke amasistimu ebhethri le-lithium-ion, amabhethri e-lithium iron phosphate ochungechungeni afanelana kahle kakhulu ne-voltage ephumayo yebhethri lelead-acid.Isibonelo, i-voltage yokusebenza yebhethri ye-lithium iron phosphate icishe ibe ngu-10V kuya ku-14.6V, kuyilapho amandla ogesi okusebenza asebenzayo webhethri le-lead-acid engu-12V ngokuyisisekelo aphakathi kuka-10.8V no-14.4V.
- Impilo ende yesevisi.Njengamanje, phakathi kwawo wonke amabhethri e-accumulator amile embonini, amabhethri e-lithium iron phosphate anokuphila komjikelezo omude kakhulu.Kusukela esicini semijikelezo yempilo yeseli ngayinye, ibhethri le-lead-acid licishe libe izikhathi ezingama-300, ibhethri ye-lithium ye-ternary ingafinyelela izikhathi eziyi-1000, kanti ibhethri ye-lithium iron phosphate ingadlula izikhathi ezingama-2000.Ngokuthuthukiswa kwenqubo yokukhiqiza, ukuvuthwa kobuchwepheshe bokugcwalisa i-lithium, njll., imibuthano yempilo yebhethri ye-lithium iron phosphate ingafinyelela izikhathi ezingaphezu kwezi-5,000 noma izikhathi ezingu-10,000.Ngemikhiqizo yebhethri yesitoreji samandla sasekhaya, nakuba inani lemijikelezo lizonikelwa ngokwezinga elithile (futhi likhona kwamanye amasistimu ebhethri) ngokwandisa inani lamaseli ngamanye ngokuxhumeka ochungechungeni (ngesinye isikhathi ngokuhambisana), ukushiyeka kochungechunge oluningi. kanye namabhethri ahambisanayo amaningi azolungiswa ngokulungiswa kobuchwepheshe bokubhanqa, ukuklama komkhiqizo, ubuchwepheshe bokukhipha ukushisa kanye nobuchwepheshe bokulawula ibhalansi yebhethri ngezinga elikhulu ukuze kuthuthukiswe impilo yesevisi.
