Ukuqonda iMigaqo yokuTshaja kunye noBude bexesha leeTshaja ze-AC EV

Njengoko izithuthi zombane (EVs) zixhaphake kakhulu, ukubaluleka kokuqonda imigaqo yokutshaja kunye nobude be-AC (i-alternating current) iishaja ze-EV azikwazi ukugqithiswa.Makhe sijonge ngakumbi ukuba itshaja zeAC EV zisebenza njani kunye nezinto ezinefuthe kwixesha lokutshaja.

Imigaqo yokutshaja:

Iitshaja ze-AC zixhomekeke kumgaqo wokuguqula umsinga otshintshanayo ukusuka kwigridi ukuya kumandla akhoyo ngokuthe ngqo (DC) afanele ukutshaja ibhetri ye-EV.Nalu ulwahlulo lwenkqubo yokutshaja:

1. Ukuguqulwa kwamandla: Itshaja ye-AC ifumana umbane kwigridi kwi-voltage ethile kunye nokuphindaphinda.Iguqula amandla e-AC abe ngamandla eDC afunwa yibhetri ye-EV.

2. Itshaja ekwibhodi: Itshaja ye-AC idlulisela umbane we-DC oguqulweyo kwisithuthi ngetshaja engaphakathi.Le tshaja ihlengahlengisa amandla ombane kunye neyangoku ukuze ihambelane neemfuno zebhetri zokutshaja okukhuselekileyo nokufanelekileyo.

Ubude bexesha lokutshaja:

Ubude bexesha lokutshaja kweetshaja ze-AC EV kuxhomekeke kwizinto ezininzi ezinokuphembelela isantya sokutshaja kunye nexesha.Nantsi imiba ephambili ekufuneka iqwalaselwe:

1. INqanaba loMbane: Iitshaja ze-AC ziza kumanqanaba ahlukeneyo ombane, ukusuka kwi-3.7kW ukuya kwi-22kW.Amanqanaba aphezulu ombane avumela ukutshaja ngokukhawuleza, ukunciphisa ixesha lokutshaja ngokubanzi.

2. Umthamo webhetri: Ubungakanani kunye nomthamo wepakethi yebhetri ye-EV idlala indima ebalulekileyo ekumiseleni ixesha lokutshaja.Ibhetri enkulu iya kufuna ixesha elininzi lokutshaja ngokupheleleyo xa kuthelekiswa nencinci.

3. I-State of Charge (SoC): Isantya sokutshaja sihlala sihla njengoko ibhetri isondela kumthamo wayo opheleleyo.Uninzi lweetshaja ze-AC ziyilelwe ukuba zitshaje ngokukhawuleza kumanqanaba okuqala kodwa zicothe njengoko ibhetri ifikelela kwi-80% yesakhono sokukhusela ubomi bayo obude.

4. Itshaja ye-Onboard yeSithuthi: Ukusebenza kakuhle kunye nokukwazi ukuphuma kwamandla etshaja ekwibhodi yesithuthi kunokuchaphazela ubude bexesha lokutshaja.Ii-EVs zixhotyiswe ngeetshaja ezikwibhodi ephucukileyo zinokuphatha amandla aphezulu, okukhokelela kumaxesha okutshaja okukhawulezayo.

5. I-Voltage yeGrid kunye neyangoku: I-voltage kunye ne-current ebonelelwa yigridi inokuchaphazela isantya sokutshaja.I-voltage ephezulu kunye namanqanaba angoku avumela ukutshaja ngokukhawuleza, ngaphandle kokuba i-EV kunye netshaja inokuhlangabezana nazo.

Isiphelo:

Iitshaja ze-AC EV ziququzelela ukutshajiswa kwezithuthi zombane ngokuguqula umsinga otshintshanayo ube ngumsinga othe ngqo wokutshaja ibhetri.Ubude bexesha lokutshaja kweetshaja ze-AC liphenjelelwa zizinto ezinje ngenqanaba lamandla, umthamo webhetri, imeko yentlawulo, ukusebenza kakuhle kwetshaja ekwibhodi, kunye nombane wegridi kunye nangoku.Ukuqonda le migaqo kunye nezinto zenza ukuba abanini be-EV basebenzise iqhinga labo lokutshaja kwaye bacwangcise iihambo zabo ngokufanelekileyo.
