Inkqubo yokugcina amandla (ESS), njengoko igama lisitsho, yinkqubo esetyenziselwa ukugcina amandla, enokubhekisa ekuguqulweni kwamandla ombane kwinkqubo yamandla abe luhlobo oluthile lwesixhobo esinokugcina amandla ukuze aguqulwe abe ngamandla ombane xa kufuneka. Umbane ongenakuqhekeka (UPS) ngumthombo wamandla okufaka obonelela ngamandla angxamisekileyo kumthwalo xa umbane ophambili wesixhobo sombane usilela, osetyenziselwa ukukhusela isixhobo esineemfuno eziphezulu zokuzinza kombane. Kwimeko yokusilela, ibonelela ngamandla e-AC angasemva kwisixhobo somthwalo wombane ngaphandle kokuphazamiseka ukugcina ukusebenza okuqhelekileyo kwesixhobo sombane. Ezi ntsilelo ziquka ukucima kombane, ukungasebenzi kakuhle kwamandla ombane, ukuphazamiseka okanye ukunyuka kwamandla.

I-ESS iyonke yahlukile kwinkqubo ye-UPS.

Okokuqala, ukusetyenziswa kwenkqubo ye-UPS sisicwangciso sengxakeko esenzeka xa umbane ophambili ungaphumeleli. Ukongeza kwingxakeko, umbane kwi-ESS usetyenziselwa umthwalo ophezulu kwiimeko ezininzi, kwaye usetyenziselwa "ukusika okuphezulu kunye nokuzalisa intlambo" ngezinye iintlobo zamandla, njengamandla enyukliya, amandla omoya, amandla elanga, njl. Amandla anokudluliselwa ukunciphisa iindleko, okanye ukunceda loo mithombo yamandla engaqhubekiyo ukuba ithunyelwe ngaphandle ngokuthe chu. okwesibini, i-UPS, njengenkqubo yongxamiseko, idla ngokugcina uzinzo lwezixhobo ezibalulekileyo, ukuze zibe nexesha lokucima ngokuqhelekileyo okanye de umbane ongxamisekileyo uvuleke, ngoko ke ixesha alide kakhulu, linokuba yimizuzu elishumi okanye imizuzu embalwa, uze uvule umbane ongxamisekileyo, umbane ongxamisekileyo unokuvela kwinkqubo ye-ESS okanye kwezinye iijenereyitha ezilindileyo. Okokugqibela, inkqubo ye-UPS ikwanazo nezixhobo zokugcina umbane, ezinye iinkqubo ze-UPS zisebenzisa inkqubo ye-flywheel ukugcina umbane, ezinye iinkqubo ze-UPS zisebenzisa iinkqubo zebhetri ukugcina umbane, kodwa nakwixesha loxolo ukutshaja inkqubo yokugcina umbane, xa inkqubo yombane ephambili idibana nokusilela, i-UPS iqala ukubonelela ngombane ongaphazanyiswayo.
