Prologue EX
Honda reliability meets electric. Here's what its onboard charger actually needs from your home's electrical panel.
Home (Level 2) charging facts
Pulled straight from the Prologue EX's onboard charger rating - not a generic EV number.
- Onboard charger draw
- 11.5 kW
- ~48A at 240V (kW × 1000 ÷ 240)
- Empty-to-full at max Level 2
- 7.4 hrs
- 85 kWh battery ÷ 11.5 kW
- Range added per hour
- ~33 mi/hr
- 11.5 kW × 2.9 mi/kWh efficiency
- DC fast charging
- 150 kW max
- Public chargers only - tapers as the battery fills
Typical full-speed install
48A charger on a 60A circuit
Reaches this car's 11.5 kW ceiling. Whether your panel has room for that circuit depends on everything else already on it - that's the actual assessment.
Connector
CCS
CCS (Combined Charging System) is the most common connector on non-Tesla EVs for both home Level 2 charging and public DC fast charging.
On the Prologue EX specifically, that connector carries up to 11.5 kW at home on Level 2 and up to 150 kW on public DC fast hardware.
Charging speed by circuit size
The Honda Prologue's onboard charger can't use more than 11.5 kW AC no matter how big the circuit - past 48A, a bigger charger buys you nothing on this car.
| Charger setting | This car actually draws | Range added / hour | 8-hr overnight |
|---|---|---|---|
| 16A | 3.8 kW | ~11 mi | ~88 mi |
| 24A | 5.8 kW | ~17 mi | ~136 mi |
| 32A | 7.7 kW | ~22 mi | ~176 mi |
| 40A | 9.6 kW | ~28 mi | ~224 mi |
| 48A | 11.5 kWcapped by car | ~33 mi | ~264 mi |
Overnight, at full onboard speed
264 mi / 8 hrs
330 mi across a 10-hour window, at 11.5 kW.
Approximate cost to fill from empty
$11.05
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 85 kWh - about $0.045/mile.
Honda Prologue charging questions
How long does it take to charge a 2024–2026 Honda Prologue EX on a Level 2 charger?
About 7.4 hours from empty to full at its 11.5 kW onboard-charger ceiling (85 kWh battery ÷ 11.5 kW).
Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Honda Prologue draw on Level 2?
At its full 11.5 kW rate, the Honda Prologue draws about 48A at 240V (kW × 1000 ÷ 240 = amps).
Can a Honda Prologue use a 48-amp charger?
Not to any real benefit. The Honda Prologue's onboard charger tops out at 11.5 kW (~48A) - a 48A charger doesn't charge it any faster than one already sized to 48A.
How much range does a Honda Prologue add per hour on a Level 2 charger?
About 33 miles of range per hour at its 11.5 kW ceiling (11.5 kW × 2.9 mi/kWh efficiency).
How much range does an 8-hour overnight charge add to a Honda Prologue?
Roughly 264 miles from an 8-hour overnight charge (33 mi/hr × 8 hours), or about 330 miles across a 10-hour window.
What's the DC fast charging ceiling for a Honda Prologue?
Up to 150 kW on a public DC fast charger - well above its 11.5 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
