Usoro ịkwụ ụgwọ EV na-ebuga ike site na grid ọkụ gaa na batrị EV, n'agbanyeghị na ị na-eji chaja AC n'ụlọ ma ọ bụ DC ngwa ngwa n'ụlọ ahịa na okporo ụzọ. Ọ na-ebuga ike site na ụgbụ ọkụ na batrị maka nchekwa. N'ihi na ọ bụ naanị ike DC ka enwere ike ịchekwa na batrị ahụ, enweghị ike ibunye ike AC na batrị ozugbo, ọ kwesịrị ka chaja onboard gbanwee ya ka ọ bụrụ ike DC.
Ọtụtụ ndị mmadụ na-echegbu onwe ha na chaja ngwa ngwa dị elu ga-abụ nnukwu ihe ịma aka maka grid ọkụ ma ọ bụ obere ojiji nke chaja ngwa ngwa DC. Mana yana teknụzụ na-emepe emepe yana ọtụtụ EVs n'okporo ụzọ, ịchaji ngwa ngwa ga-abụ ihe siri ike.
Enwere ike kewaa ọkọlọtọ nchaji na ụkpụrụ 5, nke bụ CHAdeMO (Japan), GB/T (China), CCS1 (US), CCS2 (EU) na Tesla.
