How Much Does It Cost to Charge a Honda Prologue in Rhode Island?

Quick Answer

Charging a 2026 Honda Prologue at home in Rhode Island costs approximately $90/month — that's $0.090/mile and saves $506/year compared to a 28 MPG gas car at Rhode Island's gas price of $3.70/gallon.

SUVs balance cargo space with reasonable efficiency, making them the most popular EV body style in the U.S. — and this one handles that balance well. Cold weather reduces EV range by 20–40% as the battery heats itself and the cabin. Use scheduled departure to pre-heat on shore power before driving.

About the 2026 Honda Prologue

The Honda Prologue is Honda's first volume-market EV in North America — built on GM's Ultium platform while Honda develops its own e:Architecture. It offers 296 miles of range at $47,400, giving Honda buyers an accessible path to electrification.

Advantages

✓296 miles of range covers most daily and weekend driving

✓Built on GM's proven Ultium platform — mature technology

✓Honda brand reputation for reliability expected to carry over

✓Qualifies for $7,500 federal tax credit

Considerations

✗Built on GM platform means Honda had limited input on key EV architecture decisions

✗150 kW DCFC is average — below 800V competitors at similar prices

✗Interior is GM-sourced rather than Honda-developed

✗Honda's own EV platform (e:Architecture) coming 2027 may make Prologue feel transitional

Ideal Buyer

Honda CR-V and Pilot owners who want to go electric with familiar Honda brand trust. Buyers who want the federal tax credit on a mainstream brand EV.

vs. Gas Equivalent

Direct EV replacement of the Honda CR-V or Pilot. Gas equivalent is a Honda CR-V at approximately 31 MPG.

EV Ownership in Rhode Island

Rhode Island has growing EV adoption, largely in the Providence metro. As the smallest state, range anxiety is essentially nonexistent — a single charge covers the entire state multiple times over.

Incentives & Programs

Rhode Island offers the Drive Electric RI rebate (up to $1,500 for new EVs). National Grid RI and Providence Energy offer off-peak EV charging rates. The state participates in the TCI (Transportation Climate Initiative) framework.

Charging Infrastructure

I-95 through Providence is well-served. Newport and coastal areas are growing. Given the state's tiny size (48 miles long), there's no long-distance concern — any DCFC on I-95 can serve most of the state.

Grid & Energy Source

Rhode Island's grid is a mix of natural gas (~90%) and small renewables — the state lacks space for large-scale generation. However, offshore wind projects planned for RI Sound will significantly change this picture.

Rhode IslandElectricity Rates & EV Savings

The average residential electricity rate in Rhode Island is $0.27/kWh, which is above the national average of $0.17/kWh. With a gas price of $3.70/gallon, Rhode Island ranks as a moderate state for EV ownership.

Tips for Charging Your Honda Prologue in Rhode Island

Rhode Island's cold climate and charging infrastructure have specific implications for Honda Prologue owners. Here are practical tips to maximize range and minimize charging costs in this state:

Rhode Island's tiny size means a single overnight Level 2 charge easily covers a week of commuting.

National Grid RI's off-peak EV rate is ~$0.10/kWh — low enough to make EV economics compelling despite the high base rate.

Providence's compact geography makes Level 2 public charging more practical here than in most states.

Offshore wind development offshore RI will make the grid substantially cleaner by 2027–2028.
