Amaseli elanga ayingxenye ebalulekile yanoma isiphi isimiso samandla elanga ngoba agcina amandla akhiqizwa ama-solar panel ukuze asetshenziswe lapho ukukhanya kwelanga kuphansi noma ebusuku.Njengoba amandla elanga ethandwa kakhulu, isidingo samaseli elanga anokwethenjelwa futhi ahlala isikhathi eside siyaqhubeka sikhula.Ngakho-ke, abathengi abaningi bafuna ulwazi lapho amaseli elanga ahlala isikhathi eside kakhulu.Kulesi sihloko, sizohlola izinhlobo ezahlukene zamaseli elanga atholakalayo futhi sixoxe ngokuthi yimaphi aziwa ngokuhlala kwawo nokuphila isikhathi eside.
Kunezici eziningana okufanele uzicabangele lapho ukhetha iseli elifanele lelanga.Lokhu kufaka phakathi uhlobo lwebhethri, umthamo, impilo yomjikelezo kanye nokusebenza kukonke.Izinhlobo ezahlukene zamaseli elanga zinezici ezihlukile futhi zenzelwe ukuhlangabezana nezidingo ezithile zokugcina amandla.Ezinye zezinhlobo zebhethri zelanga ezivame kakhulu zihlanganisa amabhethri e-lead-acid, amabhethri e-lithium-ion, namabhethri okugeleza.
Amabhethri e-lead-acid asetshenziswe amashumi eminyaka futhi aziwa ngokuthembeka kwawo kanye nezindleko eziphansi.Kodwa-ke, anempilo yomjikelezo elinganiselwe futhi angadinga ukunakekelwa ngezikhathi ezithile.Ngakolunye uhlangothi, amabhethri e-lithium-ion aya ngokuya aduma ngenxa yokuminyana kwawo okuphezulu kwamandla, impilo yomjikelezo omude, kanye nezidingo eziphansi zokugcinwa kwazo.Nakuba engavamile kangako, amabhethri agelezayo aziwa ngokuqina kwawo kanye nempilo yomjikelezo omude, okuwenza afanelekele izinhlelo zokusebenza zokugcina amandla ezinkulu.
Amabhethri e-lithium-ion ngokuvamile abhekwa njengenketho engcono kakhulu mayelana nokuphila isikhathi eside.Lawa mabhethri aziwa ngamandla awo aphezulu, okubavumela ukuthi bagcine amandla amakhulu endaweni ehlangene.Ukwengeza, amabhethri e-lithium-ion anempilo yomjikelezo omude, okusho ukuthi angashajwa futhi ashajwe izikhathi eziyizinkulungwane ngaphandle kokuwohloka okukhulu.Lokhu kubenza balungele izinhlelo zamandla elanga njengoba zinganikeza iminyaka yokugcina amandla okuthembekile.
Esinye sezici eziyinhloko ezithinta ukuphila kwengqamuzana lelanga yimpilo yalo yomjikelezo.Impilo yomjikelezo isho inani lokushajwa nemijikelezo yokukhipha ibhethri elingadlula ngaphambi kokuthi umthamo walo wehle kakhulu.Kumaseli elanga, ukuphila komjikelezo omude kuyadingeka njengoba kuqinisekisa ukuthi ibhethri lingaqhubeka nokugcina nokuletha amandla ngendlela ephumelelayo esikhathini eside.Amabhethri e-lithium-ion aziwa ngokuphila kwawo okumangalisayo komjikelezo, kanti amanye amamodeli akwazi ukuhlala izikhathi eziyi-10,000 noma ngaphezulu.
Okunye okucatshangelwayo okubalulekile lapho kuhlolwa impilo ye-solar cell ukuthi amandla ayo agcinwa kahle kangakanani ngokuhamba kwesikhathi.Njengoba ibhethri likhula, amandla ayo okugcina ukushajwa angase anciphe.Kodwa-ke, amabhethri e-lithium-ion aziwa ngokugcina umthamo wawo omuhle kakhulu, namamodeli amaningi agcina u-80% noma ngaphezulu womthamo wawo wangempela ngemva kwezinkulungwane zemijikelezo.Lokhu kusho ukuthi ngisho nangemva kweminyaka yokusetshenziswa, amabhethri e-lithium-ion asengakwazi ukunikeza isitoreji samandla esibalulekile sezinhlelo zamandla elanga.
Ngaphezu kokuphila komjikelezo nokugcinwa kwamandla, ukusebenza okuphelele kweseli yelanga nakho kudlala indima ebalulekile ekunqumeni ubude bayo besikhathi eside.Amaseli elanga asezingeni eliphezulu aklanyelwe ukusebenza kahle nangokwethembeka ngisho nangaphansi kwezimo eziyinselele.Lokhu kufaka phakathi izici ezifana nokubekezelela izinga lokushisa, ukujula kokukhishwa, kanye nekhono lokumelana nokushaja okuvamisile nemijikelezo yokukhipha.Amabhethri e-lithium-ion aziwa ngokusebenza kwawo okuhle kakhulu kulezi zindawo, okuwenza abe yisinqumo sokuqala sokugcina amandla elanga ahlala isikhathi eside.
Lapho ukhetha iseli lelanga elizohlala isikhathi eside kakhulu, kufanele ucabangele izidingo ezithile zesistimu yakho yamandla elanga.Izinto ezinjengosayizi wesistimu, izidingo zokugcina amandla kanye nesabelomali konke kuthonya ukukhethwa kwamaseli elanga.Ukufakwa kwendawo yokuhlala yelanga, amabhethri e-lithium-ion avame ukuthandwa ngenxa yobuningi bawo bamandla, impilo yomjikelezo omude kanye nezidingo zokugcinwa okuphansi.Lawa mabhethri anganikeza ukugcinwa kwamandla okuthembekile ezindlini futhi angahlanganiswa kalula nezinhlelo ezikhona zamandla elanga.
Kuzinhlelo zokusebenza zesitoreji selanga esikhulu, njengamaphrojekthi esikali sokuthengisa, amabhethri agelezayo angaba inketho efanelekile.Amabhethri agelezayo aziwa ngempilo yawo yomjikelezo omude kanye nokuqina, okuwenza alungele ukugcina amanani amakhulu wamandla.Nakuba zingaba nezindleko eziphezulu ezingaphambili uma kuqhathaniswa nezinye izinhlobo zebhethri, ukuphila kwazo isikhathi eside nokusebenza kwazo kuzenza zibe yisixazululo esingabizi kakhulu sezidingo zesikhathi eside zokugcina amandla.
Ekuphetheni, kumaseli elanga, ukuphila isikhathi eside kuyisici esibalulekile okufanele sicatshangelwe.Amabhethri e-lithium-ion aziwa kabanzi ngokuqina kwawo kanye nempilo yomjikelezo omude, okuwenza abe ukukhetha okuhle kakhulu kwezinhlelo zamandla elanga.Ngobuningi bawo bamandla aphezulu, ukugcinwa kwamandla kanye nokusebenza okuphelele, amabhethri e-lithium-ion anganikeza isitoreji samandla esithembekile sokufakwa kwelanga okuhlala kanye nokuhweba.Njengoba isidingo samandla elanga siqhubeka sikhula, ukutshala imali kumaseli elanga asezingeni eliphezulu anesikhathi eside sokuphila kubalulekile ekwandiseni izinzuzo zamandla elanga nokuqinisekisa ikusasa lamandla esimeme.
