Detailed Network Comparisons
What It Costs to Own and Charge a Honda Prologue
The 2025 Honda Prologue uses 27.6 kWh per 100 miles on the EPA cycle — equivalent to about 122 MPGe. That efficiency drives every cost figure on this page. At the national average home rate of 16.5¢/kWh, driving 100 miles costs $4.55. At a 48¢/kWh fast charger, the same 100 miles costs $13.25 — 1304 dollars more over the course of 15,000 miles a year.
Real-world efficiency typically lands 5–15% worse than EPA figures because of highway speeds, cold-weather battery heating, and climate control load. In winter at 20°F, expect the Prologue's consumption to climb to roughly 34.5 kWh per 100 miles — about 25% worse than the EPA rating. This matters most for road-trip planning: budget your stops for 60–70% of the rated 308-mile range between charges if you want margin for detours and cold weather.
The Prologue's DC fast-charging peak of 155 kW is only held briefly — typically between 10% and 40% state of charge. From 40% to 80%, charging speed tapers as the battery management system throttles to protect longevity. The 10→80% charging window takes roughly 18 min on a capable charger. For home Level 2 on a 11.5 kW charger, a full empty-to-full charge takes about 5h 55m — easily overnight.
The CCS port on the Prologue determines which networks you can use natively. CCS (Combined Charging System) is supported by Electrify America, EVgo, ChargePoint, and most non-Tesla networks. Many Tesla Superchargers now offer CCS-compatible "Magic Dock" plugs, and several automakers are shipping NACS adapters in 2025–2026. Plan road trips around compatible stations using apps like A Better Routeplanner (ABRP) or PlugShare — Google Maps is improving but still misses many newer chargers.
Five-year total cost of charging for the Prologue at 12,000 miles/year: at home national average, roughly $2,732.14. At a mix of 80% home + 20% public fast charging (typical for commuters who take occasional road trips), roughly $3,510.39. Compare that to a gas equivalent at 28 mpg and $3.50/gallon: roughly $7,500 over the same 60,000 miles. The fuel savings are the single biggest operating-cost advantage of EV ownership.
Frequently Asked Questions
How much does it cost to charge a Honda Prologue?
At the national average electricity rate of 16.5¢/kWh, a full charge for a Honda Prologue (85 kWh battery) costs approximately $11.22 at home. At public DC fast chargers, costs typically range from $17.68 to $30.60.
What connector does the Honda Prologue use?
The 2025 Honda Prologue uses a CCS connector. This means it is compatible with charging networks that support CCS standard connectors.
How long does it take to charge a Honda Prologue?
At a DC fast charger (up to 155 kW), charging from 20% to 80% takes approximately 16 min. On a Level 2 home charger (11.5 kW), a full charge from empty takes about 5h 55m.
What is the cheapest way to charge a Honda Prologue?
Home charging is almost always the cheapest option for the Honda Prologue. In low-rate states like Idaho or Washington (10.5¢/kWh), a full charge costs $7.14. Among public networks, IONNA and Francis Energy currently offer the lowest rates at 24–30¢/kWh.
How efficient is the Honda Prologue in kWh per mile?
The Honda Prologue uses approximately 27.6 kWh per 100 miles (EPA rated). This is equivalent to about 122 MPGe.
