Hawaii home charging cost for the 2026 Volvo EC40
A 2026 Volvo EC40 draws 31.7 kWh per 100 miles per the EPA; at Hawaii's 45.95¢/kWh residential rate that's $14.56 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home costs a little less than gas here: 9.1% less than gas per mile, here specifically.
2026 Volvo EC40: yearly cost in Hawaii
At fueleconomy.gov's default of 15,000 annual miles, the 2026 Volvo EC40 costs roughly $2,184 a year to charge at home in Hawaii, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $219 a year.
Cost of a full charge
Covering the 2026 Volvo EC40's EPA-rated 298-mile range takes about 94.4 kWh, which costs about $43.38 at Hawaii's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.
Where this ranks
This combination ranks 19,927 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Volvo EC40 alone ranks 82 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.
