2026 Volvo EC40 Twin: home charging cost in Rhode Island

A 2026 Volvo EC40 Twin draws 34.8 kWh per 100 miles per the EPA; at Rhode Island's 29.45¢/kWh residential rate that's $10.26 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: 36% less than gas per mile, here specifically.

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 Rhode Island electrician to quote the install before this math becomes a real decision.
