Ukuthuthukiswa kwamabhethri okugcina amandla kuqhutshwa yisidingo semakethe futhi kuguquke ngokuhlukene emikhakheni ehlukene efana nesitoreji esikhulu, indawo yokugcina amandla yasendlini, kanye nokugcinwa kwamandla ezimbonini nezohwebo. Lawa mabhethri athuthuke kakhulu ngokuya ngokusebenza, okuhlanganisa umthamo omkhulu, amandla athile aphezulu, umjikelezo omude kakhulu, kanye nebanga lokushisa elibanzi. Njengoba iziteshi zamandla okugcina amandla ziba zinkulu, isidingo somthamo webhethri, ukuphepha, nempilo yomjikelezo siyakhula. Kodwa-ke, okwamanje ayikho indlela ecacile yokukhethwa kwebhethri emkhakheni wokugcinwa kwamandla ezimbonini ezishisayo nezohwebo, njengoba kugxilwe ezinzuzweni zezomnotho kanye nokusebenza kahle kwezindleko. Noma kunjalo, sekukhona umfutho emakethe wamabhethri amakhulu ukuze asekele imikhiqizo yokugcina amandla ezimbonini nezohwebo.

Emkhakheni wokugcina amandla wasendlini, ukukhethwa kwamabhethri nakho kugxile emakethe. Ukuthambekela kokugcinwa kwamandla kagesi wasendlini kanye nemishini yasendlini kubangele ukusetshenziswa kwemiklamo efana namathebhu agcwele izigxobo namasilinda amakhulu. Amandla ebhethri angaphansi kuka-50Ah kanye no-50Ah-100Ah ayatholakala kusitoreji samandla sasendlini. Kulo nyaka uwodwa, izinkampani zamabhethri ezingaphezu kuka-20 zethule amamodeli angaphezu kuka-30 angu-300Ah+ noma ngaphezulu kwamabhethri okugcina amandla, anamandla afana ne-314Ah, 320Ah, ne-325Ah. Ukwenyusa umthamo wamabhethri okugcina amandla akuthuthukisi nje kuphela ukuminyana kwamandla nempilo yomjikelezo kodwa futhi kuveza izinselele ezifana nokunqanyulwa kokushisa nokusabalalisa ukushisa okungalingani, okudinga idizayini yokuphepha yezinga eliphezulu nokuthuthukiswa kwenqubo.

Ukwenyuka kwamandla amabhethri okugcina amandla nakho kuholela ekuthuthukisweni kwamandla ezinhlelweni zokugcina amandla. Isibonelo, amasistimu okugcina amandla esiqukathi esijwayelekile samamitha angu-20 anamabhethri angu-300Ah+ ngokuvamile akhuphule umthamo wawo ukusuka ku-3MWh+ ukuya ku-5MWh+, ehlisa izindleko zokuqala zomhlaba nengqalasizinda yamaphrojekthi okugcina amandla. Lokhu kuthuthukiswa kokusebenza kumabhethri okugcina amandla angu-300Ah+ kuwumphumela wokuhlola okuqhubekayo kwezinkampani zamabhethri ezintweni zokwakha, ukukhiqiza, nobuchwepheshe. Ukusetshenziswa kwabaqoqi bamanje abayinhlanganisela, ngokwesibonelo, kuphephile futhi kungokonga futhi kulindeleke ukuthi kube isizukulwane esilandelayo sezinto eziqoqiwe zamanje. Bangakwazi ukuvimbela ukukhula kwe-lithium dendrites, ukuvimba okwamanje ngesikhathi sokubhoboza, futhi kuvimbele ukugijima okushisayo, kuthuthukise ukuphepha kwamabhethri okugcina amandla amakhulu.

Mayelana nenqubo nokukhiqiza, izindlela ezimbili okwamanje ziyahlolwa. Esokuqala sigxile ekwandiseni ukwakheka kwendawo kwangaphakathi kwebhethri, kuyilapho okwesibili kwephula umumo ongokwemvelo futhi sithuthukele kumadizayini amade, amancanyana, nanjenge-blade. Ubuchwepheshe obuphezulu, isibonelo, bunciphisa indawo ephezulu yamabhethri okugcina amandla, ukwandisa ukusetshenziswa kwendawo nokuthuthukisa amamethrikhi okusebenza njengomthamo wangempela, impilo yomjikelezo, nokusebenza kahle kwamandla. Emikhiqizweni yokugcina amandla ezimbonini nezentengiso, ikhambi lamanje elijwayelekile ukusebenzisa amabhethri angu-280Ah, kodwa ukugxila kulindeleke ukuthi kushintshele kumabhethri angu-300Ah+ ngokuzayo. Amabhethri amakhulu anikeza izinzuzo eziphezulu kulawa makhasimende, ehlisa inani lemikhiqizo esetshenzisiwe futhi axazulule izingqinamba zesikhala. Ukwengeza, amabhethri amakhulu anganciphisa izindleko ngokunciphisa izingxenye ezihlanganisiwe nokugcina impilo yomjikelezo omude, ngaleyo ndlela ehlise izindleko zikagesi esikhathini sokuphila somkhiqizo.

Emakethe yokugcina amandla yasendlini, izimo eziyinhloko zohlelo lokusebenza ziyi-backup yamandla eziphuthumayo zasendlini kanye nokusetshenziswa kwezinhlelo "ze-photovoltaic + yokugcina amandla". Lezi zimo zidinga amabhethri anesilinganiso esihle sokusebenza, ngokuvamile phakathi kuka-0.5-1C. Omunye umkhuba wokugcina amandla wasendlini ukusetshenziswa kwamandla kagesi aphezulu, okufinyelelwa ngokuxhuma amabhethri amaningi ochungechungeni. Lokhu kubangela ama-currents esistimu amancane, ukuphazamiseka okuncane, nokusebenza kahle kokuguqulwa okuphezulu. Kodwa-ke, ukuthambekela kokugcinwa kwamandla kagesi wasendlini ane-voltage ephezulu kudinga ukuhambisana kwebhethri okuphezulu, okwenza amabhethri angama-cylindrical abe yisinqumo esihle njengoba enikeza ukungaguquguquki okungcono ngenxa yezinqubo zokulungiselela ezivuthiwe. Kulindeleke ukuthi amabhethri amakhulu angama-cylindrical azoqhubeka nokwandisa izinga lawo lokungena endaweni yokugcina amandla yasendlini.

Sekukonke, ukuvela kokusebenza kwamabhethri okugcina amandla kuhambisana eduze nesidingo semakethe. Intuthuko yenziwe emikhakheni ehlukahlukene, futhi ubuchwepheshe bebhethri obuhlukene buthuthukisiwe ukuze buhlangabezane nezidingo ezithile. Umthamo okhulayo wamabhethri okugcina amandla uletha kokubili izinselele namathuba mayelana nokusebenza, ukuphepha, kanye nokusebenza kahle kwezindleko. Ukuhlola okuqhubekayo nokuthuthukiswa kwezinto zokwakha, ukukhiqiza, kanye nobuchwepheshe kuzothuthukisa ukusebenza nokwamukelwa kwamabhethri okugcina amandla ezinhlelweni ezihlukahlukene.
