Yini amandla aphezulu?
Amandla aphezulu
I-SOP (Isimo Samandla) ibhekisela esimweni samandla esiphezulu sephakethe lebhethri, okungamandla amakhulu ibhethri elingawadedela noma liwamunce phakathi nesikhathi esinqunyiwe ngaphambili. Amandla aphezulu angasetshenziselwa ukuhlola imikhawulo yokushaja nokukhipha ibhethri lamandla ngaphansi kwezimo ezihlukene zokushajwa, okudlala indima ebalulekile ekuthuthukiseni ukufanisa phakathi kwephakethe lebhethri lamandla nokusebenza kwamandla emoto, kanye nokuthuthukisa umsebenzi wokubhuleka ovuselelayo wemoto kagesi. Futhi inenani elibalulekile lethiyori nengokoqobo lokusetshenziswa okunengqondo kwamabhethri, ukugwema ukushajwa kakhulu{2}}noma ngaphezulu{2}}ukuchithwa, ukuthuthukisa ukuphepha kwebhethri, nokwelula impilo yebhethri. Nokho, amandla aphezulu ebhethri angaphansi kwemikhawulo eminingi yokuphepha; amandla aphezulu kuphela ngaphakathi kwale mikhawulo yokuphepha anokubaluleka okungokoqobo. Lesi sigaba sidingida amapharamitha ebhethri akhawulela amandla aphezulu futhi sihlola ubudlelwano phakathi kokuphepha kwebhethri namandla aphezulu.
Izingqinamba ezisuselwe kuzinga lokushisa{0}
I-conductivity ye-electrolyte kanye nomsebenzi wezinto ze-anode ne-cathode kushintsha ngezinga lokushisa, ngaleyo ndlela kuthinte umkhawulo ongaphezulu wokushaja kwebhethri namandla okukhipha. Izinga lokusabela kwama-electrode liyancipha njengoba izinga lokushisa lincipha. Izinga lokushisa liphinde lithinte amazinga okuthutha ama-ion nama-electron ku-electrolyte. Lawa mazinga akhuphuka ngokukhuphuka kwezinga lokushisa futhi ngokuphambene nalokho. Ngaphezu kwalokho, uma izinga lokushisa liphezulu kakhulu, lidlula umkhawulo wokushisa oshiwo, ibhalansi yamakhemikhali ngaphakathi kwebhethri izophazamiseka, okubangele izinkinga zokuphepha kwebhethri.
Njengoba kuboniswe kuMfanekiso 8-31, amandla aphezulu ebhethri ashintsha nezinga lokushisa, abonise ngokusobala ijika elingelona umugqa. Amandla aphezulu ayancipha njengoba izinga lokushisa lincipha, lishintsha kancane emazingeni okushisa aphansi. Ngenkathi amandla aphezulu enyuka ngezinga lokushisa elikhuphukayo, amazinga okushisa aphezulu kakhulu enza ukuchithwa kokushisa kube nzima, kube nomthelela omubi ukuphepha kwebhethri nempilo yokuphila.
Imikhawulo{0}esuselwe ku-SOC
I-State of Charge (SOC) Umkhawulo Wesimo Sokusebenza (i-SOP) uklanyelwe ukuvimbela ukushajwa ngokweqile kanye{0}}nokukhipha ngaphezulu{0}}kwebhethri phakathi nokusebenza, ukuqinisekisa ukuphepha kwebhethri. Lapho utadisha ubudlelwano phakathi kwamandla aphezulu kanye ne-SOC, umthelela wezinto ezifana nezinga lokushisa kanye nenani lokushaja/lokukhipha ku-SOC kumele nalo licatshangelwe ukuze kuthuthukiswe ukunemba kokulinganisa kwe-SOC. Njengoba kuboniswe ku-Figure 8-32, njengoba i-SOC ikhula, amandla okukhipha ayanda ngenkathi amandla okushaja ehla. Isibonelo, ngaphakathi kwebanga elifanayo le-SOC, lapho i-SOC ikhuphuka isuka ku-10% iye ku-90%, amandla okukhipha okuphezulu akhuphuka ukusuka ku-222W kuya ku-693W, kuyilapho amandla okushaja aphezulu ehla ukusuka ku-675W kuya ku-300W. Ukufunda amandla aphezulu ngaphansi kwezimo ezihlukene ze-SOC kungalinganisela ukushajwa/umthamo wokuphuma webhethri, kunikeze idatha nosekelo lobuchwepheshe ukuze lusetshenziswe ezimotweni zikagesi.
Imikhawulo esekelwe ekuphikiseni i-ohmic
Njengoba kuboniswe kuMfanekiso 8-33, amandla aphezulu ebhethri acishe alingane ngokuphambene nokumelana kwawo ne-ohmic yangaphakathi. Okuncane ukumelana kwangaphakathi kwe-ohmic, amandla amakhulu futhi asheshayo; okukhudlwana ukumelana kwangaphakathi kwe-ohmic, amandla amancane futhi ahamba kancane.
Izinga lokushisa lebhethri, isimo sokushaja (i-SOC), nokumelana kwangaphakathi konke kuhlobene eduze nesimo salo sokuphepha. Ngakho-ke, isimo sokusebenza kwebhethri (i-SOP) kufanele sihlangabezane nemikhawulo ebekwe yilezi zinto ezintathu ukuze kuqinisekiswe ukusebenza okuphephile nokwelula impilo yayo.
