Obusobozi bwennyini obw’okufulumya bbaatule ezibadde zikola mu mbeera ya float-charge okumala ebbanga eddene butera obutategeerekeka bulungi. Okwesigamira ku nkola eza bulijjo zokka ez’okugezesa obusobozi kiwa obutuufu obutono. Wadde ng’enkyukakyuka mu vvulovumenti ya bbaatule n’obuziyiza obw’omunda zisobola okulaga ekitundu ku kukendeera kw’obusobozi, ebipimo bino si bipimo bikakafu okupima obusobozi bwa bbaatule.
Ekigonjoola kyokka ekyesigika kwe kukola okugezesa obusobozi buli luvannyuma lwa kiseera nga tuyita mu nsengekera za chajingi-okufulumya ezifugibwa. Kino kikakasa nti bbaatule zikola ku bitundu ebitakka wansi wa 80% ku busobozi bwazo, okutuukiriza ebyetaago by’emigugu gya DC mu biseera by’amasannyalaze ga AC n’okuzuula ensonga za bbaatule eziyinza okubaawo. Kino kintu kikulu nnyo mu kwesigika kw’enkola y’amasannyalaze ga DC.
DFUN Battery Bank Capacity Testing Solution egatta emirimu mingi, omuli okulondoola okuva ewala ku yintaneeti, okugezesa okufulumya obusobozi, okucaajinga mu ngeri ey’amagezi mu bitundutundu, okukola n’okuddaabiriza bbaatule mu ngeri ey’amagezi, okutebenkeza bbaatule n’okugikola. Esaanira enkola z’amasannyalaze ga DC nga amasannyalaze g’amasimu (48V) n’amasannyalaze agakola (110 & 220V).
Nga bazimba ku myaka egy’obukugu mu by’ekikugu n’okukozesebwa mu nkola z’amasannyalaze ga DC, DFUN ekoze enkola z’okugezesa obusobozi bwa bbanka ya bbaatule ku yintaneeti mu kiseera ekituufu. Obuyiiya obukulu kwe kuleeta ekitongole ekikuuma amazzi agafuluma, ekisobozesa okugezesa obusobozi okukolebwa mu mbeera ezikuumibwa.
Ekitundu ekikuuma okufulumya kirimu dayode ey’oludda olumu ne contactor eggaddwa mu ngeri eya bulijjo eyungiddwa mu parallel n’oluvannyuma n’eyingizibwa mu circuit y’okugabira bbaatule. Mu kiseera ky’okugezesa obusobozi, dayode ekakasa nti okucaajinga kuyimirira nga okufuluma kugenda mu maaso. Kino kiremesa ekyuma ekicaajinga okuwa kasasiro mu bbanka ya bbaatule, ne kiteeka bbanka ya bbaatule mu mbeera ey’ebbugumu (real-time online). Ka kibeere nti enkola y’okugezesa obusobozi bw’ekola, bbanka ya bbaatule esigala ku mutimbagano. Singa wabaawo okulemererwa mu kyuma ekicaajinga oba enkola ya AC, bbanka ya bbaatule egaba amangu amasannyalaze eri omugugu gwa DC.
Enkola y’okugezesa obusobozi ku yintaneeti okuva ewala ku masannyalaze g’amasimu (48V)
Enkola y’okugezesa obusobozi ku yintaneeti okuva ewala ku masannyalaze agakola (110V & 220V)
K1 esigala nga nzigale, ng’eyunga bbanka ya bbaatule ne bbaasi ya DC/ekyuma ekicaajinga.
Bbanka ya bbaatule esobola okucaajinga n’okufulumya. Singa enkola ya AC/ekyuma ekicaajinga kiremererwa, bbanka ya bbaatule egaba amaanyi mu kiseera ekituufu eri omugugu gwa DC.
Amasannyalaze g'amasimu (48V)
K1 Open, KM Closed: Battery efuluma ng’eyita mu DC/DC step-up discharge unit n’eyungibwa ku DC bus. Mu mbeera eno, vvulovumenti efuluma mu nkola y’okugezesa obusobozi eba waggulu okusinga vvulovumenti y’amasannyalaze ga DC, okukakasa nti omugugu guweebwa amaanyi okuva mu nkola y’okugezesa obusobozi (bbanka ya bbaatule). Circuit ya diode (D1) eyimiriza okucaajinga, ekisobozesa okufulumya.
Amasannyalaze agakola (110V & 220V)
K1 Open, K11 Closed: Bbanka ya bbaatule efuluma ng’eyita mu inverter ya PCS, n’eyingiza amaanyi okudda mu AC grid. Circuit ya diode (D1) eyimiriza okucaajinga, ekisobozesa okufulumya.
Mu bika byombi eby’enkola, ekitundu ekikuuma okufulumya (K/D) kikakasa nti ne bwe wabaawo ensobi mu nkola ya AC, ekyuma ekicaajinga, oba enkola y’okugezesa obusobozi, bbanka ya bbaatule esigala ng’esobola okuwa amaanyi mu kiseera ekituufu eri omugugu gwa DC. Okuddamu kuno okw’amangu kumatiza obwetaavu bw’amasannyalaze obw’amangu mu mbeera ezisukkiridde.
Nga egatta ekitundu ekikuuma okufulumya (K/D) mu nkulungo y’okugabira bbaatule, enkola eno ekakasa nti amasannyalaze gava mu bbanka ya bbaatule agataliiko kutaataaganyizibwa mu kiseera ky’okugezesa okufulumya obusobozi buli luvannyuma lwa kiseera. Kino kyongera obukuumi n’obwesigwa bw’enkola z’amasannyalaze ga DC, ne kiwa obukuumi obw’amaanyi eri emirimu emikulu.
