Ukutshaja kwe-AC vs DC: Zithini umahluko?

Umbane ngumqolo wazo zonke izithuthi zombane. Nangona kunjalo, ayizizo zonke umbane ezinomgangatho ofanayo. Kukho iintlobo ezimbini eziphambili zombane: i-AC (i-alternating current) kunye ne-DC (i-direct current). Kule posi yebhlog, siza kuhlola umahluko phakathi kokutshaja kwe-AC kunye ne-DC kunye nendlela ezichaphazela ngayo inkqubo yokutshaja kwezithuthi zombane. Kodwa ngaphambi kokuba singene kwiinkcukacha, masicacise into kuqala. Umbane otshintshanayo yinto evela kwigridi yamandla (oko kukuthi, iplagi yakho yasekhaya). Umbane othe ngqo ngamandla agcinwe kwibhetri yemoto yakho yombane.

Ukutshaja kwe-EV: umahluko phakathi kwe-AC kunye ne-DC

 Amandla eDC

 Amandla e-DC (amandla angoku ngqo) luhlobo lwamandla ombane ahamba kwicala elinye. Ngokungafaniyo namandla e-AC, atshintsha icala ngamanye amaxesha, amandla e-DC ahamba kwicala elingaguqukiyo. Ahlala esetyenziswa kwizixhobo ezifuna umthombo wamandla ongaguqukiyo nozinzileyo, njengeekhompyutha, iithelevishini, kunye neefowuni eziphathwayo. Amandla e-DC aveliswa zizixhobo ezifana neebhetri ze-EV kunye neephaneli zelanga, ezivelisa ukuhamba okungaguqukiyo kombane. Ngokungafaniyo namandla e-AC, anokuguqulwa ngokulula abe zii-voltage ezahlukeneyo kusetyenziswa ii-transformers, amandla e-DC afuna inkqubo yokuguqula enzima ngakumbi ukutshintsha i-voltage yawo.

Amandla e-AC

Amandla e-AC (alternating current) luhlobo lwamandla ombane atshintsha icala ngamanye amaxesha. Icala le-AC voltage kunye ne-current litshintsha rhoqo, ngesiqhelo kwi-frequency ye-50 okanye i-60 Hz. Icala le-electrical current kunye ne-voltage lijika rhoqo, yiyo loo nto libizwa ngokuba yi-alternating current. Umbane we-AC uhamba ngemigca yombane uye ekhayeni lakho, apho ufikeleleka khona ngeendawo zombane.

Iingenelo kunye neengxaki zokutshaja i-AC kunye ne-DC

 Iingenelo zokutshaja i-AC:

1. Ukufikeleleka. Ukutshaja kwe-AC kuyafikeleleka kubantu abaninzi kuba kungenziwa kusetyenziswa iplagi yombane eqhelekileyo. Oku kuthetha ukuba abaqhubi be-EV banokutshaja ekhaya, emsebenzini, okanye kwiindawo zikawonke-wonke ngaphandle kwezixhobo ezikhethekileyo okanye iziseko zophuhliso.
2. Ukhuseleko. Ukutshaja kwe-AC kudla ngokuthathwa njengokukhuselekileyo kunezinye iindlela zokutshaja kuba kunika amandla kwi-sine waveform, enokubangela ukukhwankqiswa kombane kancinci kunezinye iindlela zokutshaja.

1. Ukufikeleleka. Ukutshaja nge-AC kubiza kancinci kunezinye iindlela zokutshaja kuba akudingi zixhobo okanye iziseko ezikhethekileyo. Oku kwenza kube lukhetho olungabizi kakhulu kubantu abaninzi.

Iingxaki zokutshaja i-AC:

1. Amaxesha okutshaja acothayo.Iitshaja ze-AC zinamandla okutshaja alinganiselweyo kwaye zihamba kancinci kunezikhululo ze-DC, nto leyo enokuba yingxaki kwii-EV ezifuna ukutshaja ngokukhawuleza endleleni, njengalezo zisetyenziselwa ukuhamba umgama omde. Amaxesha okutshaja okutshaja kwe-AC anokuqala kwiiyure ezimbalwa ukuya kwiintsuku, kuxhomekeke kumthamo webhetri.

1. Ukusebenza kakuhle kwamandla.Iitshaja ze-AC azisebenzisi umbane kakuhle njengezikhululo zokutshaja ezikhawulezayo kuba zifuna i-transformer ukuze iguqule i-voltage. Le nkqubo yokuguqula ibangela ukulahleka kwamandla, nto leyo enokuba yingxaki kwabo baxhalabileyo malunga nokusebenza kakuhle kwamandla.

Ngaba i-AC okanye i-DC ingcono xa itshajwa?

Oku kuya kuxhomekeka kwiimfuno zakho zokutshaja. Ukuba uqhuba umgama omfutshane yonke imihla, ukongeza rhoqo usebenzisa itshaja ye-AC kufanele kwanele. Kodwa ukuba uhlala useluhambeni kwaye uqhuba umgama omde, ukutshaja kwe-DC yeyona ndlela ilungileyo, njengoko ungayitshaja ngokupheleleyo i-EV yakho ngaphantsi kweyure. Qaphela ukuba ukutshaja ngokukhawuleza rhoqo kunokubangela ukonakala kwebhetri njengoko amandla aphezulu evelisa ubushushu obuninzi.

Ngaba ii-EVs zisebenza kwi-AC okanye kwi-DC?

Iimoto zombane zisebenzisa umbane othe ngqo. Ibhetri ekwi-EV igcina amandla ombane kwifomathi ye-DC, kwaye injini yombane enika amandla imoto isebenza ngamandla e-DC. Ukuze ufumane iimfuno zakho zokutshaja nge-EV, jonga ingqokelela kaLectron yeetshaja ze-EV, iiadaptha, kunye nokunye okuninzi kweTesla kunye ne-J1772 EVs.
