THE IONIQ 5 AND EV6 DON'T CHARGE FAST AT TESLA SUPERCHARGERS: TESLA VS. ELECTRIFY AMERICA

EV Channels Review

This video thoroughly investigates the charging performance of the 2024 Kia EV6 GT and the 2025 Hyundai Ioniq 5 N when using Tesla Superchargers versus Electrify America's 350 kW CCS chargers. The primary finding is that while both vehicles achieve their claimed 10-80% charge in approximately 18-21 minutes on a 350 kW charger, their performance on Tesla Superchargers is significantly slower. The Ioniq 5 N, despite having a larger battery, charges about 30 kW faster than the EV6 GT on Tesla chargers, resulting in a 19-mile range advantage after 25 minutes. A notable issue identified is the "Korean Siesta" on the EV6 GT at Tesla chargers, a behavior absent in the Ioniq 5 N. The reviewer highlights that the 800-volt architecture of these Hyundai/Kia vehicles is incompatible with Tesla's 400-volt charging infrastructure, forcing them to use a workaround involving running motors in reverse, which limits charging speeds. The video concludes that while the Ioniq 5 N offers minor improvements like a battery preconditioning button and slightly better charging, the overall benefits may not justify the price increase over used models, especially considering the significant speed advantage of 350 kW CCS chargers.
