Hawaii home charging cost for the 2026 Kia EV9 Long Range AWD GT-Line

At Hawaii's residential electricity rate of 45.95¢/kWh, a 2026 Kia EV9 Long Range AWD GT-Line (rated 41 kWh per 100 miles by the EPA) costs $18.84 to drive 100 miles on home charging, against $16.02 for the same distance in a car averaging 25.5 mpg on gasoline at $4.085/gallon. This model costs more to charge at home than gas would here: 17.6% 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 Kia EV9 Long Range AWD GT-Line costs roughly $2,826 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's about $423 MORE a year than the gas comparison, not less.

Cost of a full charge

Covering the 2026 Kia EV9 Long Range AWD GT-Line's EPA-rated 280-mile range takes about 114.8 kWh, which costs about $52.75 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 20,272 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Kia EV9 Long Range AWD GT-Line alone ranks 286 of 400 models for efficiency; Hawaii alone ranks 51 of 51 states for electricity price.

Before you install a home charger in Hawaii

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.

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.
