2026 Hyundai Ioniq 5 Robo taxi, HI Charging Cost

Hawaii home charging cost for the 2026 Hyundai Ioniq 5 Robo taxi

In Hawaii, home electricity runs 45.95¢/kWh, put a 2026 Hyundai Ioniq 5 Robo taxi's EPA-rated 47.5 kWh/100mi against that and 100 miles costs $21.84, versus $16.02 for a gas car averaging 25.5 mpg. This model costs more to charge at home than gas would here: 36.3% more than gas per mile here, not less, the arithmetic isn't clamped to always favor charging.

Annual cost, at 15 thousands miles a year

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Hyundai Ioniq 5 Robo taxi costs roughly $3,276 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's about $873 MORE a year than the gas comparison, not less.

Filling up the 2026 Hyundai Ioniq 5 Robo taxi, in dollars

Covering the 2026 Hyundai Ioniq 5 Robo taxi's EPA-rated 168-mile range takes about 79.8 kWh, which costs about $36.69 at Hawaii's residential rate, figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

How this compares nationally

This combination ranks 20,368 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Hyundai Ioniq 5 Robo taxi alone ranks 375 of 400 models for efficiency; Hawaii alone ranks 51 of 51 states for electricity price.

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place, the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

Ask a licensed Hawaii electrician to quote the install before this math becomes a real decision.

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset, see the methodology guide. This is one of the combinations where charging costs more than gas, the guide to when that happens explains why the arithmetic can go either way.
