Zisetshenziswa kuphi izixhumi nezixhumi ezipholisiwe ngoketshezi zokupholisa uketshezi kuma-EV?

Izixhumi ezipholishwe ngoketshezi zisetshenziselwa ukuthwala amazinga aphezulu amandla njengalezo ezitholakala kumashaja e-EV okushaja okusheshayo kakhulu (i-XFC). Izixhumi zokupholisa ngoketshezi zivame kakhulu futhi zisetshenziselwa ukupholisa amabhethri e-EV, ukupholisa iziteshi zokushaja ze-XFC EV, kanye nezinye izinhlelo zokusebenza ezidinga ukushisa.

Le FAQ ibukeza ukusebenza kanye namacala okusetshenziswa kwezixhumi ezipholishwe ngoketshezi kanye nezixhumi zokupholisa uketshezi kuma-EV futhi ibheke imizamo yokuhlanganisa ukupholisa uketshezi kanye nomhwamuko ukuze kutholakale amazinga aphezulu kakhulu okusatshalaliswa kokushisa.

Uma ingasetshenziswa, ukupholisa umoya yisisombululo esithandwayo. Ihlanganisa ubulula nezindleko eziphansi. Kodwa ilinganiselwe ekhonweni layo lokususa ukushisa okukhulu. Izinhlelo zokupholisa uketshezi ezisekelwe emanzini zingasebenza kahle izikhathi eziphindwe kayishumi ekususeni ukushisa. Ukusebenzisa ezinye izinto eziwuketshezi kungandisa ukusebenza kahle kokushisa. Izinhlelo zokupholisa uketshezi zingase zenziwe kusengaphambili, zivalwe ngemiklamo enoketshezi ngaphakathi, futhi zilungele ukufakwa. Lokho kungenza kube lula ukwenziwa kwesistimu yokuqala, ukulungiswa, kanye nokuthuthukiswa.

Ukushaja okusheshayo kusho ukushisa okwengeziwe
Izikhathi zokushaja ezisheshayo zibalulekile ekwamukelweni kabanzi kwama-EV. Ukudlulisela amandla engeziwe kumabhethri e-EV kuhilela ukusebenzisa ama-voltage aphezulu kanye nemisinga ephezulu. Ukwandisa i-voltage kubalulekile kodwa futhi kunqunyelwe. Iningi lama-EV asemgwaqweni namuhla linama-voltage ephakethe lamabhethri angaba ngu-400 V, kanye nama-battery packs angu-800 kuya ku-900 V amele umkhawulo ophambili. Umgomo we-XFC ukuletha amandla okushaja afinyelela ku-500 kW. Ngisho noma kune-battery pack engu-900 V, lokho kudinga amandla amaningi futhi kuqeda ukushisa okuningi.

E-US, imboni ye-EV ijwayele kakhulu isixhumi sesistimu yokushaja ehlanganisiwe (CCS), esibizwa nangokuthi isixhumi se-SAE J1772 combo, esingasekela ukushaja kwe-AC noma imishini yokushaja okusheshayo ye-DC. Ngaphandle kokupholisa uketshezi, izixhumi ze-CCS zingasekela amandla okushaja afinyelela ku-200 kW; ngokwengeza ukupholisa uketshezi kwabathintana nabo, isilinganiso samandla singakhushulwa sifike ku-500 kW (500 A ku-1 kV).
Ukupholisa ngoketshezi kuvumela nokusetshenziswa kwezintambo ezincane, ezilula ukuphatha amazinga aphezulu wamandla. Ngaphandle kokupholisa okusebenzayo, izintambo zingaba nzima kakhulu futhi zingaphatheki kalula ngabasebenzisi.

Ukupholisa uketshezi kuyisimo esidingekayo kodwa esinganele ukusekela ukushaja kwe-EV okungu-500 kW ngendlela ephumelelayo. Ukuphathwa kokushisa okusebenzayo, okuhlanganisa nokuqapha izinga lokushisa, kuyadingeka kumashaja e-EV anamandla aphezulu. Ukuqapha kwesikhathi sangempela kuyadingeka ukuqinisekisa ukuthi izinga lokushisa alidluli umkhawulo wencazelo ye-+50°C (Isithombe 2). Isibonelo, uma kwenzeka ukugcwala ngokweqile noma izinga lokushisa elizungezile likhuphuka ngokungalindelekile (ilanga liphuma ngemuva kwefu), uhlelo ludinga ukukwazi ukuphendula ukuqinisekisa ukusebenza okuphephile ngokushesha. Kuye ngezimo kanye nomklamo wesistimu, impendulo ingaba ukwandisa izinga lokupholisa noma ukunciphisa izinga lokushaja ukuze kugcinwe izinga lokushisa lokuxhumana kwesixhumi likhuphuka ngaphansi komkhawulo we-+50°C.

Asebenza Kanjani Amashaja Asheshayo Okupholisa Okumanzi?

Amashaja asheshayo okupholisa uketshezi asebenzisa izintambo ezipholiswe uketshezi ukusiza ukulwa namazinga aphezulu okushisa ahlobene nesivinini esikhulu sokushaja. Ukupholisa kwenzeka kusixhumi ngokwaso, kuthumela isifudumezi sigeleze ngekhebula futhi singene ekuthinteni phakathi kwemoto nesixhumi. Ngenxa yokuthi ukupholisa kwenzeka ngaphakathi kwesixhumi, ukushisa kuyanyamalala cishe ngokushesha njengoba isifudumezi sihamba phakathi kweyunithi yokupholisa nesixhumi. Izinhlelo zokupholisa uketshezi ezisekelwe emanzini zingasusa ukushisa ngokusebenza kahle izikhathi eziyishumi, kanti ezinye iziphuzo zingathuthukisa ukusebenza kahle kokupholisa. Ngakho-ke, ukupholisa uketshezi kuthola ukunakwa okwengeziwe njengesixazululo esisebenza kahle kakhulu esitholakalayo.

Ukupholisa ngoketshezi kuvumela izintambo zokushaja ukuthi zibe zincane futhi zibe lula, kunciphisa isisindo sezintambo cishe ngo-40%. Lokhu kwenza kube lula kumthengi ojwayelekile ukuzisebenzisa lapho eshaja imoto yakhe.

Izixhumi zoketshezi olupholisa uketshezi zenzelwe ukuqina nokumelana nezimo zangaphandle ezifana namazinga aphezulu okushisa, ukubanda, umswakama kanye nothuli. Zenzelwe futhi ukumelana nengcindezi enkulu ukugwema ukuvuza nokuzigcina ziphila phakathi nesikhathi eside sokushaja.

Inqubo yokupholisa uketshezi kumashaja ezimoto zikagesi ivame ukuhilela uhlelo oluvaliwe. Ishaja ifakwe i-heat exchanger exhunywe ohlelweni lokupholisa, olungapholiswa umoya noma olupholiswe uketshezi. Ukushisa okukhiqizwa ngesikhathi sokushaja kudluliselwa ku-heat exchanger, bese kuyidlulisela ku-coolant. I-coolant ivame ukuba yingxube yamanzi kanye ne-coolant additive, njenge-glycol noma i-ethylene glycol. I-coolant ijikeleza ohlelweni lokupholisa lweshaja, imunce ukushisa bese ikudlulisela ku-radiator noma ku-heat exchanger. Ukushisa bese kuhlakazeka emoyeni noma kudluliselwe ohlelweni lokupholisa uketshezi, kuye ngomklamo weshaja.

Uhlelo lokushaja lwe-CCS2 olupholishwe ngamandla aphezulu lwe-500A 600A luyisiteshi sokujikeleza esizinikele esibekwe phakathi kwekhebula nesixhumi sokushaja se-CCS2. I-cooling medium ingezwa esiteshini, bese uketshezi lujikeleziswa ngephampu yamandla ukuze kuphole futhi kushabalaliswe ukushisa.
Iziteshi zokushaja okusheshayo kudingeka zisebenze kahle. Lokhu kubaluleke kakhulu. Kusemongweni wokukhula okusheshayo kwezimoto zikagesi. Empeleni, lokhu kusebenza kahle kudinga ukuphathwa okuhle kokushisa. Futhi, kuvela esidingweni esikhulayo sokushaja okusheshayo.
