Ukushaja kwe-AC vs DC: Yimiphi Umehluko?

Ugesi uwumgogodla wazo zonke izimoto zikagesi. Kodwa-ke, akuwona wonke ugesi onekhwalithi efanayo. Kunezinhlobo ezimbili eziyinhloko zamandla kagesi: i-AC (alternating current) kanye ne-DC (direct current). Kulesi sihloko sebhulogi, sizohlola umehluko phakathi kokushaja kwe-AC ne-DC nokuthi kuthinta kanjani inqubo yokushaja yezimoto zikagesi. Kodwa ngaphambi kokuba singene emininingwaneni, ake sicacise okuthile kuqala. Ukushintshana kwamandla yilokho okuvela kugridi yamandla (okungukuthi, indawo yakho yokukhipha amanzi endlini). Ugesi oqondile amandla agcinwe ebhethri lakho lemoto kagesi.

Ukushaja kwe-EV: umehluko phakathi kwe-AC ne-DC

 Amandla e-DC

 Amandla kagesi e-DC (amandla kagesi aqondile) uhlobo lwamandla kagesi ageleza ohlangothini olulodwa. Ngokungafani namandla e-AC, ashintsha indlela ngezikhathi ezithile, amandla e-DC ageleza ohlangothini olungaguquki. Avame ukusetshenziswa kumadivayisi adinga umthombo wamandla ohlala njalo, ozinzile, njengamakhompyutha, amathelevishini, nama-smartphone. Amandla e-DC akhiqizwa ngamadivayisi afana namabhethri e-EV namaphaneli elanga, akhiqiza ukugeleza okungaguquki kwamandla kagesi. Ngokungafani namandla e-AC, angaguqulwa kalula abe ama-voltage ahlukene kusetshenziswa ama-transformer, amandla e-DC adinga inqubo yokuguqula eyinkimbinkimbi kakhulu ukushintsha i-voltage yawo.

Amandla e-AC

Amandla e-AC (alternating current) uhlobo lwamandla kagesi ashintsha indlela ngezikhathi ezithile. Indlela i-AC voltage kanye ne-current eziqondisa ngayo ishintsha ngezikhathi ezithile, ngokuvamile ngemvamisa engu-50 noma 60 Hz. Indlela i-electric current kanye ne-voltage eziqondisa ngayo ishintsha ngezikhathi ezithile, yingakho ibizwa ngokuthi i-alternating current. Ugesi we-AC ugeleza ngezintambo zikagesi uye ekhaya lakho, lapho ungafinyeleleka khona ngezindawo zikagesi.

Izinzuzo kanye nokubi kokushaja kwe-AC kanye ne-DC

 Izinzuzo zokushaja i-AC:

1. Ukufinyeleleka. Ukushaja i-AC kufinyeleleka kubantu abaningi ngoba kungenziwa kusetshenziswa i-socket kagesi ejwayelekile. Lokhu kusho ukuthi abashayeli be-EV bangashaja ekhaya, emsebenzini, noma ezindaweni zomphakathi ngaphandle kwemishini ekhethekile noma ingqalasizinda.
2. Ukuphepha. Ukushaja i-AC ngokuvamile kubhekwa njengokuphephile kunezinye izindlela zokushaja ngoba kunikeza amandla ngesimo se-sine wave, okungenzeka ukuthi kungabangela ukushaqeka kukagesi kunezinye izinhlobo zamagagasi.

1. Ukungabizi. Ukushaja i-AC kushibhile kunezinye izindlela zokushaja ngoba akudingi imishini ekhethekile noma ingqalasizinda. Lokhu kwenza kube inketho engabizi kakhulu kubantu abaningi.

Izinkinga zokushaja i-AC:

1. Izikhathi zokushaja ezisheshayo.Amashaja e-AC anamandla okushaja alinganiselwe futhi ahamba kancane kuneziteshi ze-DC, okungaba yiphutha kuma-EV adinga ukushaja okusheshayo emgwaqweni, njengalawo asetshenziselwa ukuhamba ibanga elide. Izikhathi zokushaja zokushaja i-AC zingasukela emahoreni ambalwa kuya ezinsukwini, kuye ngokuthi ibhethri linamandla kangakanani.

1. Ukusetshenziswa kahle kwamandla.Amashaja e-AC awasebenzisi amandla amaningi njengeziteshi zokushaja ezishesha kakhulu ngoba adinga i-transformer ukuze aguqule i-voltage. Le nqubo yokuguqula iholela ekulahlekelweni kwamandla athile, okungaba yiphutha kulabo abakhathazekile ngokusebenza kahle kwamandla.

Ingabe i-AC noma i-DC ingcono ekushajeni?

Lokhu kuzoncika ezidingweni zakho zokushaja. Uma ushayela amabanga amafushane nsuku zonke, khona-ke ukwengeza njalo usebenzisa ishaja ye-AC kufanele kwanele. Kodwa uma uhlala usendleleni futhi ushayela amabanga amade, ukushaja kwe-DC kuyindlela engcono, njengoba ungashaja i-EV yakho ngokugcwele ngaphansi kwehora. Qaphela ukuthi ukushaja okusheshayo njalo kungabangela ukuwohloka kwebhethri njengoba amandla aphezulu ekhiqiza ukushisa okuningi.

Ingabe ama-EV asebenza ku-AC noma ku-DC?

Izimoto zikagesi zisebenza ngogesi oqondile. Ibhethri eliku-EV ligcina amandla kagesi ngefomethi ye-DC, kanye nenjini kagesi enika amandla imoto ukuthi isebenze ngamandla e-DC. Ukuze uthole izidingo zakho zokushaja i-EV, hlola iqoqo likaLectron lamashaja e-EV, ama-adapter, nokuningi kwe-Tesla kanye ne-J1772 EV.
