Inzuzo enkulu yeshaja esemotweni ukuthi isebenzisa amandla e-AC angekho eshalofini, angaxhunywa kunoma iyiphi yezigidigidi zezitolo ezifakwe kuso sonke isakhiwo ngocingo olulodwa.
Ukushaja kweleveli 1 AC kusebenzisa amandla esigaba esisodwa, ukunikezwa kwamandla ka-120V cishe ku-1.9KW, ukunikezwa kwamandla okungu-220V-240V cishe ku-3.7KW.Lena indlela evame kakhulu yokushaja ezindlini zangasese.
Kodwa-ke, izinkampani ngokuvamile zisebenzisa umthombo wamandla wezigaba ezintathu ukushaja, ongakhuphula amandla atholakalayo amashaja angaphakathi ebhodini abe cishe ku-20kW, ngokushesha kakhulu kunesigaba sokuqala sokushaja.
Ukushaja kwe-AC kuyindlela evumelana nezimo kakhulu yokushaja, njengoba isiteshi sokushaja singanikeza uhla olugcwele lwezidingo zokushaja ngokusekelwe endleleni yokuphila yomsebenzisi nokusetshenziswa kwemoto.Uma imoto isetshenziselwa ukuhamba emini kuphela, ukushaja ebusuku kulula kakhulu.Ukushaja kwe-AC akulungile ukushaja okunwetshiwe ngoba isikhathi sokushaja side kakhulu futhi nebanga elidingekayo lingaphezu kwebanga lemoto.
Izingxenye ze-passive zamashaja emoto
Amadivayisi angenzi lutho afana nezakhi kazibuthe nama-capacitor adlala indima ebalulekile kuzo zonke izici zamashaja asebhodini.Isiguquli se-boost esakha isiphetho esingaphambili sesiteji se-PFC sizoba nesihlungi semodi evamile ye-EMC, ama-capacitor okuhlunga, amakhoyili e-PFC, kanye ne-DC link capacitor enikeza isitoreji sokushaja phakathi kwesiteji sokuthuthukisa kanye neshaja esebhodini.
Iziguquli ze-LLC zisetshenziswa kakhulu ezinhlelweni zezimboni nezabathengi.Nakuba kusetshenziswa i-click ethize ekhishwayo, izakhi kazibuthe zisetshenziselwa ukuhlukanisa izihlungi ze-EMC nezikhiphayo, kanye nama-capacitor ahlukahlukene.
Amandla okusebenzisa ukushaja okungenantambo aholele esidingweni esibanzi sezingxenye ze-passive, okuhlanganisa amakhoyili okudlulisa amandla (ukuthumela nokwamukela), njengoba kukhonjisiwe ngakwesokudla, kanye nezithonjana ze-proximity ukuqinisekisa ukuthi imoto ihambisana kahle neshaja.
Nakuba intuthuko yakamuva eminingi igxile kumadivayisi e-semiconductor yama-electronics amandla afana ne-MOSFET ne-IGBT nezilawuli ezihambisana nazo, ambalwa kulawa madivayisi akwazile ukubona amandla awo ezingxenyeni zokungenzi lutho ngaphandle kokuthuthukiswa okuhambisanayo ekusebenzeni kwawo okuncikile kanye nezixhumi nezintambo.
Ezinhlelweni eziningi, ama-resistors amaningi asetshenziswa ngokufana ukuphatha ukulahleka kwamandla okudingekayo.Nakuba lokhu kunikeza isisombululo ezingeni lesifunda, kwandisa inani lezingxenye, izindleko, kanye nesikhala sebhodi esidingekayo - akukho okufanelekile endaweni yezimoto.Ukuqamba okusha kwakamuva kube ukuphikiswa kokuqala kwamandla aphezulu okuhlinzekwa ngeziqu ze-AEC-Q200 (kwesokunxele).Lawa madivayisi okubekezelela okungu-1% ahlinzekwa ngedizayini yephakeji evalekile ukuze afakwe ngqo kurediyetha, lapho elinganiselwe kufika ku-800W.Lokhu kuchithwa kwamandla aphezulu kuvumela amadivayisi amaningi anamandla aphansi ukuthi athathelwe indawo yi-resistor eyodwa, noma (ngenxa yomthamo wayo we-pulse) i-resistor enkulu yenxeba yezintambo ingashintshwa, konga isikhala sebhodi.
I-inductor iyisakhi okuthi, uma ingakhethwanga kahle, yonakaliswe ukuchayeka isikhathi eside ekushiseni nasekudlidlizeni.Kodwa-ke, imodeli emagebhugebhu ihlangabezana namazinga e-AEC-Q200, afana nensimbi eyinhlanganisela yamandla okuqinisa nokugijima kwebhaka nesihlungi.Izinguqulo zakamuva zinikeza ukumelana nokudlidliza okuphezulu futhi ziyakwazi ukusebenza emazingeni okushisa afika ku-150°C (okuhlanganisa nokuzifudumeza), kuyilapho zigcina ukuzinza okuhle kakhulu kwe-inductance phezu kwalolu banga lokushisa olwandisiwe.Isakhiwo esivikelayo sicishe siqede ukuvuza kazibuthe, ngaleyo ndlela sinciphise noma yiziphi izinkinga zokuphazanyiswa kozibuthe.
EVumphakeli weshaja osebhodini
I-DCNEishaja esebhodiniisetshenziswa kakhulu izimoto eziyingxubevange, izimoto zikagesi ezimsulwa, amabhasi kagesi, izimoto ezisebenza ngogesi nezinye izimoto zamandla amasha, futhi ifanele ukushaja i-lithium iron phosphate, i-lithium manganese acid, i-lead acid namanye amabhethri amandla emoto.Qala ibhizinisi lakho lesiteshi sokushaja i-EV ngeI-DCNE.
Ukuze uthole ikhwowutheshini yokungabopheli intengo yakamuva yeshaja engaphakathi ebhodini noma ukwesekwa kobuchwepheshe, sicelaXhumana nathifuthi ugcwalise imininingwane yakho, futhi sizobuyela kuwe phakathi kwamahora angu-24.
