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

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.
