2026 Toyota bZ (energy capacity 191 Ah), HI Charging Cost

2026 Toyota bZ (energy capacity 191 Ah): home charging cost in Hawaii

A 2026 Toyota bZ (energy capacity 191 Ah) draws 25.5 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $11.72 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home is cheaper than gas here: 26.8% less than gas per mile, here specifically.

2026 Toyota bZ (energy capacity 191 Ah): yearly cost in Hawaii

Driving 15,000 miles a year, fueleconomy.gov's own default assumption, a 2026 Toyota bZ (energy capacity 191 Ah) charged at home in Hawaii costs about $1,758/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $645 a year.

Filling up the 2026 Toyota bZ (energy capacity 191 Ah), in dollars

Where this ranks

This combination ranks 18,851 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Toyota bZ (energy capacity 191 Ah) alone ranks 7 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.

Where these figures come from

Every figure on this page traces to a named EIA or EPA dataset, see the methodology guide. Hawaii has some of the highest residential electricity rates in the country, see the guide to why the cost varies so much by state for the full picture.
