Drivetrain and chassis

The Ioniq Electric is bundled with the portable "In-Cable Control Box" (ICCB), an electric vehicle supply equipment that allows drivers to charge their Ioniq using a conventional household outlet, but this is recommended only for use in emergencies in countries with 120V AC outlets. In most countries with 220240V AC household outlets, 100% range can be added with an overnight charge. The charging plug of the car is located in a position where fuel fillers are normally located; the vehicle is equipped with a CCS Combo 1 inlet, accepting charging rates at up to 100 kW at a DC fast charging station.
