Home vs. public fast charging
Costs below are for a 10%–80% charge — the usable fast-charge window, about 77 kWh of the Hyundai Ioniq 9’s 110 kWh battery. That’s the range most owners actually use, since charging past 80% slows down sharply.

Charging the Hyundai Ioniq 9 on public DC fast chargers costs roughly 2.9× more than at home — about $25.02 extra per 10→80% charge. Most owners charge at home and only use fast charging on road trips, so your real average lands much closer to the home number.
Level 1 vs. Level 2: can your outlet keep up?
The cost per kWh is the same either way. What changes is how fast the Hyundai Ioniq 9 recovers range while parked at home.
Level 1 · standard outlet
~4 mi/hour
120V · no installation needed
~11 hours to recover 40 miles of driving. A 10-hour overnight plug-in adds about 36 miles.
Level 2 · 240V circuit
~29 mi/hour
240V · uses the Hyundai Ioniq 9’s 9.6 kW onboard charger
~1 hour to recover 40 miles. A 10-hour overnight plug-in adds up to 288 miles.
If your daily driving stays under ~36 miles, a regular outlet may be all the Hyundai Ioniq 9 needs. Drive more than that, and Level 2 — or a workplace charger — becomes the difference between an EV that fits your life and one that doesn’t.
Does a Level 2 install pay for itself?
A home Level 2 setup — 240V circuit plus charger — typically runs $800–$1,800 installed. If the alternative is relying on public fast chargers, home charging the Hyundai Ioniq 9 in New Jersey saves about $108.33/month at 12,000 miles a year.
At a mid-range install cost of $1,300, that’s a payback of roughly 12 months — and every month after that is pure savings.
Winter in New Jersey
New Jersey averages about 4 months a year cold enough to cut EV efficiency — typically 15–25% in deep winter. Here’s what that does to the Hyundai Ioniq 9’s numbers at a 20% efficiency loss:
Cost per mile
~7.3¢vs. 5.8¢ in mild weather
Full-charge range
~264 mivs. ~330 mi
The cost bump is minor — a few dollars a month. The range cut matters more: if your daily driving is close to the Hyundai Ioniq 9’s limits, winter is when a marginal charging setup stops working.
