Isisombululo seSikhululo soMbane esiTsha esiThuthwayo sase-Odipie: Ukuqina okuNgcono kunye neendleko eziNciphisiweyo

U-Odipie utyhila isisombululo sesikhululo samandla esiphathwayo esiphucukileyo esibonelela ngokuqina okuphezulu ngexabiso eliphantsi kakhulu. Ngokuyila ngoyilo lweseli enye, soyisa imida yeebhetri zemveli, ezifana nokuwohloka kokusebenza ngenxa yokungalingani kweeseli. Ubuchwepheshe bethu obudibeneyo budibanisa imisebenzi emininzi kwibhodi enye, kunciphisa ubunzima kunye neendleko zezinto. Isiphumo sisisikhululo samandla se-1000Wh esithembekileyo kakhulu nesikhuphisana ngeendleko, esifanelekileyo kwiindidi ezahlukeneyo zezicelo.

Izitishi zoMbane eziThuthwayo bezithengiswa iminyaka eliqela. Zidibanisa iindlela zokunxibelelana nezixhobo ezahlukeneyo zombane, ezifana neeports ze-5.1V USB, iziphumo ze-12V DC, kunye neeplagi ze-110V/220V AC, ngelixa ziphatheka lula, nto leyo ezenza zithandwe ngabantu abathanda izinto zangaphandle. Ngaphandle kokujonga iimeko zazo zokusetyenziswa, eli nqaku lizisa isisombululo soyilo esitsha esinciphisa iindleko, siphucule ukusebenza, kwaye siphucule ukuqina.

Izikhululo zoMbane ezininzi eziphathwayo ezikhoyo kwimarike zisebenzisa kakhulu iipakethi zebhetri ze-12.8V okanye ze-25.6V lithium iron phosphate (LFP), oko kuthetha ukuba ezi pakethi ziqulathe ubuncinane iiseli ezine ezidityanisiweyo kuthotho. Njengoko sisazi, iiseli ezininzi ezidityanisiweyo kuthotho, kokukhona imfuneko yokuba iseli ihlale injalo iphezulu. Ngexesha lokusetyenziswa, ukuba iseli enye ihlangabezana nokuwohloka kokusebenza, oku kunokuchaphazela kakhulu ukusebenza kwepakethi yebhetri iyonke. (Ngokoqikelelo lwam, ukuba ukusebenza kweseli enye kwehla nge-5%, ukusebenza kwepakethi yebhetri iyonke kunokwehla nge-5% × 4 = 20%.)

Izisombululo ezikhoyo zifuna ukuhambelana okuphezulu kweeseli, nto leyo enyusa iindleko. Ukuba kusetyenziswa iiseli ezinokuhambelana okuncinci, ubomi bebhetri bufutshane kakhulu, nto leyo ekhokelela ekubeni umsebenzisi angabi namava amahle—isiphumo esijolise ekusiphepheni.

Isisombululo sethu esitsha sijongana ngempumelelo nezi ngxaki:

Iseli enye ithatha indawo yeeseli ezininzi ezidityanisiweyo ngothotho. Umzekelo, ukwenza iSitishi soMbane esiThuthwayo se-1000Wh, isisombululo sethu sisebenzisa iseli yebhetri enye ye-3.2V 314Ah LiFePO4 edityaniswe nebhodi yokukhusela i-BMS ye-300W ejikelezayo. Le ndlela isusa isidingo seemfuno zokungaguquguquki kweseli, ithintela imiba yokungalingani kwevolthi, kwaye isusa isidingo senkqubo yokuhlanganisa ipakethi, ngaloo ndlela inciphisa iindleko. Ukongeza, ibhodi yethu ye-inverter ye-300W ejikelezayo idibanisa imisebenzi emine: ukhuseleko lwe-BMS yebhetri, isilawuli setshaja yelanga i-MPPT, i-inverter, kunye nolawulo oluphambili, okonga kakhulu iindleko zezinto.

Nangona kunjalo, esi sisombululo sinomda omnye ophawulekayo: ngenxa yemida yamandla okukhupha iseli enye, amandla okukhupha awanakuba phezulu kakhulu. Ngokwethiyori, amandla aphezulu anokufikelela kwi-1000W, kodwa oku kuya kufuna ibhodi yesekethe ekwaziyo ukusingatha imisinga ephezulu, nto leyo eya kunyusa kakhulu iindleko. Xa kujongwa zonke izinto, ulungiselelo lweseli enye yeSikhululo soMbane esiThuthwayo se-1000Wh (1004Wh) se-300W sisisombululo esifanelekileyo.
