What a Hyundai Ioniq 9 costs to charge
The 2027 Hyundai Ioniq 9 uses 38 kWh per 100 miles on the EPA combined cycle and is rated for 320 miles, so a full charge pulls 121.6 kWh from the wall. That EPA figure is measured at the socket, which means it already includes charging losses — the cost below is what your meter records, not an idealised battery number.
What that costs depends entirely on where you plug in. Nevada has the cheapest residential electricity in the country at 13.11¢ per kWh, making a full charge $15.94. Hawaii charges 52.72¢, and the same charge costs $64.11 — 4.0× more for exactly the same miles.
Pick your state below for the local figure, or use the calculator to enter your own tariff — most people on a time-of-use plan pay well under the state average if they charge overnight.
Worth knowing: in Hawaii the flat residential electricity rate is high enough that this car costs more to run than a 30 mpg petrol equivalent. An off-peak tariff usually reverses that, but the headline rate does not.
