Using a DC fast-charge outlet, an all-electric Hyundai can charge most of its battery in up to 54 minutes. An all-electric Hyundai will fully recharge at home with a 220V or 240V outlet in approximately 6 hours for IONIQ EV models and 9.5 hours for KONA EV models. However, keep in mind that various factors can affect charging times, such as outside temperatures and State of Charge. In regard to the latter, if the State of Charge is below 20% or above 80%, the battery will charge at a slower rate.
