Ezindaweni eziphezulu zemboni kawoyela negesi, lapho imisebenzi isebenza khona ubusuku nemini, ukwethembeka kwezinhlelo zokuphakelwa kwamandla akuyona nje imfuneko kodwa kuyisidingo esibalulekile. Izisombululo zebhethri eziyisipele zidlala indima ebalulekile ekuqinisekiseni ukusebenza okungaphazamiseki kulo mkhakha.
Umkhakha kawoyela negesi uyinkimbinkimbi ngokwemvelo. Lokhu kufakwa kuncike kakhulu ekunikezweni kwamandla okungaguquki ukuze kugcinwe ubuqotho bokusebenza, ukuphatha ukuqoqwa kwedatha, izinqubo zokulawula, nokuqinisekisa ukuphepha kwezisebenzi. Ukuphazamiseka kokuphakelwa kukagesi kungaholela ekuphazamisekeni okukhulu kokusebenza noma ngisho nokwehluleka okuyinhlekelele, okwenza amasistimu okulondoloza aqinile abe semqoka kakhulu. Amabhethri ekhophi yasenqolobaneni asebenza njengehluleka ukuphepha ngokumelene neziphazamiso ezinjalo, enikeza amandla abalulekile ngesikhathi sokucima kuze kube yilapho amasistimu ayinhloko ebuyiselwa noma kuze kube enye imithombo iza ku-inthanethi.
Kulesi simo esinzima, kusetshenziswa izinhlobo ezimbalwa zamabhethri ayisipele. Okuvame kakhulu kufaka phakathi:
I-Valve Regulated Lead–Acid (VRLA) Amabhethri: Ngokwesiko athandwa ngenxa yokusebenza kahle kwezindleko nokuthembeka kwawo. Azinakekelo futhi zinebhethri ende, futhi zingasetshenziswa embonini kawoyela negesi ukuze zisebenze kwezinye zezindawo eziyinselelo enkulu emhlabeni, njengesimo sezulu esibi kakhulu, izimo ezinzima kanye namazinga okushisa aphezulu.
Amabhethri e-Nickel-Cadmium (Ni-Cd): Amabhethri e-Ni-Cd awadingi ukungezwa kwamanzi kuyo yonke impilo yawo yesevisi. Ukunakekelwa okuphansi noma okungekho, ngisho nalapho kusebenza ezindaweni ezinzima njengemboni kawoyela negesi, kanye nasezindaweni ezikude lapho ingqalasizinda ishoda khona.
Ukuze kubhekwane ngqo nalezi zidingo ngaphakathi kwezinhlelo zokusebenza zikawoyela negesi lapho ukuqapha kubalulekile kodwa kube yinselele ngenxa yesimo semvelo, i-DFUN yethule isisombululo sayo esisha, i-PBAT81 Battery Monitoring Solution.
I-DFUN PBAT81 igqama ngenxa yezici zayo ezithuthukile eziklanyelwe ukuthuthukisa ukusebenza kahle.
I-PBAT81 yakhelwe ngokukhethekile ukusetshenziswa ezindaweni ezinomfutho ophezulu, ezinomthelela omkhulu nasezindaweni lapho ukuphelelwa amandla kungaba nomthelela omkhulu ekuphepheni ngokomzimba kwabantu noma kubangele ukulimala okukhulu ezakhiweni nezakhiwo, kuzenze zingaphephile. Inika amandla ukulandelela ngesikhathi sangempela kwamandla kagesi ebhethri ngalinye, ukumelana kwangaphakathi, nezinga lokushisa elibi letheminali. Iphinde ibale i-SOC (State of Charge) kanye ne-SOH (Isimo Sezempilo).
Kumaphrojekthi asebenza embonini kawoyela negesi abheke ekuthuthukiseni imigomo yawo yokuphepha kuyilapho ethuthukisa ukusebenza kahle—ukufaka i-DFUN PBAT81 kunikeza indlela ethembisayo. Akuqinisekisi nje kuphela ukuthi amabhethri ekhophi yasenqolobaneni agcinwa ngaphansi kwezimo ezikahle zokusebenza kodwa futhi andisa isikhathi sawo sokuphila ngokuqapha okucophelela ngaleyo ndlela kuvikelwe ngempumelelo ekuphazamisekeni kwamandla okungalindelekile.
Ukufingqa, izixazululo zebhethri eziyisipele zinikeza inethi yokuphepha eqinile embonini kawoyela negesi. Njengoba ubuchwepheshe buqhubeka nokuvela futhi kuthuthukiswa izixazululo ezintsha, lezi zinhlelo zebhethri eziyisipele zizodlala indima ebalulekile ekuvikeleni amandla omhlaba wonke ekuphazamisekeni kwamandla kungazelelwe, ukuvikela ingqalasizinda ebalulekile ekuhlulekeni okungalindelekile.
