Isantya sokutshaja kunye nexesha lee-EVs zinokwahluka ngokuxhomekeke kwizinto ezininzi, kubandakanywa neziseko zokutshaja, ubungakanani bebhetri ye-EV kunye nomthamo, ubushushu, kunye nenqanaba lokutshaja.
Kukho amanqanaba amathathu okutshaja aphambili kwii-EVs
Ukutshaja iNqanaba loku-1: Le yeyona ndlela icothayo nengenamandla yokutshaja i-EV. Ukutshaja kweNqanaba loku-1 kusebenzisa i-120-volt yendlu eqhelekileyo kwaye ingathatha ukuya kwiiyure ezingama-24 ukutshaja ngokupheleleyo i-EV.
Ukutshaja kweNqanaba lesi-2: Le ndlela yokutshaja i-EV ikhawuleza kuneNqanaba 1 kwaye isebenzisa i-240-volt yokuphuma okanye isikhululo sokutshaja esizinikezele. Ukutshaja kweNqanaba le-2 kunokuthatha phakathi kweeyure ze-4-8 ukuhlawula ngokupheleleyo i-EV, kuxhomekeke kubungakanani bebhetri kunye nesantya sokutshaja.
Ukutshaja ngokukhawuleza kwe-DC: Le yeyona ndlela ikhawulezayo yokutshaja i-EV kwaye ifumaneka kwizikhululo zokutshaja zikawonke-wonke. Ukutshaja ngokukhawuleza kweDC kunokuthatha nje imizuzu engama-30 ukutshaja i-EV ukuya kwi-80% umthamo, kodwa isantya sokutshaja sinokwahluka ngokuxhomekeke kwimodeli ye-EV kunye nemveliso yamandla yesikhululo sokutshaja.
Ukubala ixesha lokuhlawula i-EV, ungasebenzisa ifomula
Ixesha lokuTshaja = (Ubungakanani bebhetri x (I-SOC ekujoliswe kuyo – i-SOC yokuQala)) Isantya sokuTshaja
Umzekelo, ukuba une-EV enebhetri engama-75 kWh kwaye ufuna ukuyitshaja ukusuka kwi-20% ukuya kwi-80% usebenzisa iNqanaba lesi-2 letshaja enesantya sokutshaja esiyi-7.2 kW, ukubala kuya kuba
Ixesha lokutshaja = (75 x (0.8 – 0.2)) / 7.2 = 6.25 iiyure
Oku kuthetha ukuba kuyakuthatha malunga neeyure ezi-6.25 ukutshaja i-EV yakho ukusuka kwi-20% ukuya kwi-80% usebenzisa i-Level 2 tshaja enesantya sokutshaja esiyi-7.2 kW. Nangona kunjalo, kubalulekile ukuqaphela ukuba amaxesha okutshaja anokwahluka ngokuxhomekeke kwiziseko zokutshaja, imodeli ye-EV, kunye nobushushu.
