This Early Hyundai Ioniq 9 Charge Test Looks Really Good
Briefly

The Hyundai Ioniq 9 exhibits strong charging performance, achieving a 10-80% charge in under 24 minutes, with a peak rate of 243 kilowatts. This rapid charging is attributed to Hyundai's 800-volt architecture, which enables higher power handling with less current and heat. However, the introduction of a Tesla-style North American Charging System port allows the Ioniq 9 to access Tesla Superchargers, but charging speeds will be significantly lower than when using compatible chargers due to the voltage discrepancy.
The Hyundai Ioniq 5 can knock out a 10-80% fast-charging session in about 20 minutes, quicker than most high-end luxury cars can manage.
The Ioniq 9 charged from 10-80% in under 24 minutes, including a peak charging rate of 243 kilowatts, aligning with Hyundai's claimed charging speed.
The Ioniq 9 is the first all-new Hyundai product to come from the factory with a Tesla-style North American Charging System (NACS) port, giving it access to Tesla Superchargers.
Charging an 800-volt system like the Ioniq 9 with a 400-volt charger involves using internal DC-to-DC converters, which can lead to inefficiencies and longer charging times.
