Inqubo yokushaja i-EV iletha amandla asuka kugridi yamandla kuya kubhethri le-EV, kungakhathaliseki ukuthi usebenzisa ukushaja kwe-AC ekhaya noma ukushaja okusheshayo kwe-DC enxanxatheleni yezitolo nakuthelawayeka. Iletha amandla asuka kunethi yamandla aye kubhethri ukuze agcinwe. Ngenxa yokuthi amandla e-DC kuphela angagcinwa ebhethrini, amandla e-AC awakwazi ukulethwa ebhethri ngokuqondile, adinga ukuguqulwa abe amandla e-DC ngeshaja engaphakathi.
Abantu abaningi bakhathazekile ngokuthi Ukushaja okusheshayo kwamandla Aphakeme kuzoba inselele enkulu kugridi yamandla noma izinga eliphansi lokusetshenziswa kweshaja esheshayo ye-DC. Kodwa kanye nobuchwepheshe obusathuthuka kanye nama-EV amaningi ngokwengeziwe emgwaqeni, ukushaja okusheshayo kungaba yisidingo esiqinile.
Izinga lokushaja lingahlukaniswa libe yizindinganiso ezi-5, okuyi-CHAdeMO (Japan), GB/T(China), CCS1 (US) ，CCS2 (EU) kanye ne-Tesla. Kulokhu, iphrothokholi yokuxhumana phakathi kwe-BMS neshaja ayifani, i-CHAdeMO kanye ne-GB/T kwamukelwa umthetho olandelwayo wokushintsha we-CAN; i-CCS1 kanye ne-CCS2 ziyizinqubo zokuxhumana ze-PLC ezamukelwayo. Ngakho-ke kubuhlungu kumsebenzisi, izwe lakhe elinazo zonke izinhlobo zezindinganiso zokushaja ama-EV, okungenzeka angatholi iziteshi zokushaja ezijwayelekile ze-DC. Emakethe, i-ABB yaklama amashaja e-DC ahlanganisa izindinganiso ezimbili zokushaja, ezixazulule izingxenye zenkinga.
Ngokuvamile, ukushaja okusheshayo kwe-DC akukhona ukushaja ibhethri ukuthi ligcwale phakathi nemizuzu embalwa, kodwa ukushaja imoto ngebanga lokushayela elinomqondo ngesikhathi esifushane, okusondela kumkhuba wokushayela imoto kaphethiloli. Ngesikhathi esifanayo, inesidingo esiphezulu sokuphepha kwebhethri.
