Ukushaja kwe-AC vs DC: Uyini Umehluko?

Ugesi uwumgogodla wazo zonke izimoto ezisebenza ngogesi. Nokho, akuwona wonke ugesi osezingeni elifanayo. Kunezinhlobo ezimbili eziyinhloko zamanje kagesi: i-AC (i-alternating current) ne-DC (i-direct current). Kulokhu okuthunyelwe kwebhulogi, sizohlola umehluko phakathi kokushaja kwe-AC ne-DC nokuthi iba nomthelela kanjani enqubweni yokushajwa kwezimoto zikagesi. Kodwa ngaphambi kokuba singene emininingwaneni, ake sicacise okuthile kuqala. Ukushintshana kwamandla yilokho okuvela kugridi yamandla (okungukuthi, indawo yakho yasendlini). I-Direct current amandla agcinwe ebhethrini lemoto yakho kagesi

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

 Amandla e-DC

 Amandla e-DC (amanje aqondile) awuhlobo lwamandla kagesi ageleza aqonde ohlangothini olulodwa. Ngokungafani namandla e-AC, ashintsha indlela ngezikhathi ezithile, amandla e-DC ageleza aye ngakuso njalo. Ivamise ukusetshenziswa kumadivayisi adinga umthombo wamandla ongashintshi, ongashintshi, njengamakhompuyutha, omabonakude, nama-smartphone. Amandla e-DC akhiqizwa amadivayisi afana namabhethri e-EV namaphaneli elanga, akhiqiza ukugeleza okuqhubekayo kwamandla kagesi. Ngokungafani namandla e-AC, angaguqulwa kalula abe ama-voltage ahlukene kusetshenziswa ama-transformer, amandla e-DC adinga inqubo yokuguqula eyinkimbinkimbi kakhulu ukuze kuguqulwe i-voltage yawo.

Amandla e-AC

Amandla e-AC (alternating current) wuhlobo lwamandla kagesi ashintsha indlela ngaso sonke isikhathi. Isiqondiso se-voltage ye-AC kanye nezinguquko zamanje ngezikhathi ezithile, ngokuvamile kuyimvamisa engu-50 noma engu-60 Hz. Isiqondiso samandla kagesi kanye ne-voltage ihlehla ngezikhathi ezithile, yingakho ibizwa ngokuthi i-alternating current. Ugesi we-AC ugeleza ezintanjeni zamandla futhi ungene ekhaya lakho, lapho ufinyeleleka khona ngezindawo zikagesi.

I-AC ne-DC yokushaja okuhle nokubi

 Ochwepheshe bokushaja i-AC:

1. Ukufinyeleleka. Ukushaja kwe-AC kufinyeleleka kubantu abaningi ngoba kungenziwa kusetshenziswa indawo kagesi evamile. Lokhu kusho ukuthi abashayeli be-EV bangakhokhisa ekhaya, emsebenzini, noma ezindaweni zomphakathi ngaphandle kwezisetshenziswa ezikhethekile noma ingqalasizinda.
2. Ukuphepha. Ukushaja kwe-AC ngokuvamile kuthathwa njengokuphephile kunezinye izindlela zokushaja ngoba iletha amandla nge-sine waveform, okungenzeka ukuthi ibangele ukushaqeka kukagesi kunamanye amagagasi.

1. Ukufinyeleleka. Ukushaja i-AC kubiza kancane kunezinye izindlela zokushaja ngoba akudingi okokusebenza okukhethekile noma ingqalasizinda. Lokhu kwenza kube inketho engabizi kakhulu kubantu abaningi.

Ububi bokushaja kwe-AC:

1. Izikhathi zokushaja ezihamba kancane.Amashaja e-AC anamandla okushaja alinganiselwe futhi anensa kuneziteshi ze-DC, okungaba ukonakala kuma-EV adinga ukushajwa okusheshayo emgwaqeni, njengalawo asetshenziselwa uhambo olude. Izikhathi zokushaja zokushajwa kwe-AC zingasukela emahoreni ambalwa kuya ezinsukwini, kuye ngomthamo webhethri.

1. Ukusebenza kahle kwamandla.Amashaja e-AC awawongi amandla njengeziteshi zokushaja ezishesha kakhulu ngoba adinga i-transformer ukuze iguqule i-voltage. Le nqubo yokuguqula iphumela ekulahlekeni kwamandla athile, okungaba yisiphukuphuku kulabo abakhathazekile ngokusebenza kahle kwamandla.

Ingabe i-AC noma i-DC ingcono ukushaja?

Lokhu kuzoncika ezidingweni zakho zokushaja. Uma ushayela amabanga amafushane nsuku zonke, khona-ke ukugcwalisa okuvamile usebenzisa ishaja ye-AC kufanele kube ngokwanele. Kodwa uma uhlezi usendleleni futhi ushayela amabanga amade, ukushaja kwe-DC iyona ndlela engcono kakhulu, njengoba ungakwazi ukushaja i-EV yakho ngokugcwele ngaphansi kwehora. Qaphela ukuthi ukushaja okusheshayo okuvamile kungabangela ukuwohloka kwebhethri njengoba amandla aphezulu akhiqiza ukushisa okukhulu kakhulu.

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

Izimoto zikagesi zisebenza ngamandla aqondile. Ibhethri ku-EV igcina amandla kagesi ngefomethi ye-DC, kanye nenjini kagesi enika imoto amandla isebenzisa namandla e-DC. Ngezidingo zakho zokushaja i-EV, hlola iqoqo le-Lectron lamashaja e-EV, ama-adaptha, nokunye okwengeziwe kwama-Tesla nama-J1772 EV.
