VF 9 Plus
3-row VinFast SUV with 123kWh battery. 10-year/125,000-mile warranty. 11kW onboard charger, 48A Level 2. Here's what its onboard charger actually needs from your home's electrical panel.
Home (Level 2) charging facts
Pulled straight from the VF 9 Plus's onboard charger rating - not a generic EV number.

- Empty-to-full at max Level 2
- 11.2 hrs
- 123 kWh battery ÷ 11 kW
- Range added per hour
- ~24 mi/hr

Typical full-speed install
48A charger on a 60A circuit
Reaches this car's 11 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 VF 9 Plus specifically, that connector carries up to 11 kW at home on Level 2 and up to 170 kW on public DC fast hardware.
Charging speed by circuit size
The VinFast VF 9's onboard charger can't use more than 11 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 | ~8 mi | ~64 mi |
| 24A | 5.8 kW | ~12 mi | ~96 mi |
| 32A | 7.7 kW | ~17 mi | ~136 mi |
| 40A | 9.6 kW | ~21 mi | ~168 mi |
| 48A | 11.0 kWcapped by car | ~24 mi | ~192 mi |
Overnight, at full onboard speed
192 mi / 8 hrs
240 mi across a 10-hour window, at 11 kW.
Approximate cost to fill from empty
$15.99
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 123 kWh - about $0.060/mile.
VinFast VF 9 charging questions
How long does it take to charge a 2025–2026 VinFast VF 9 Plus on a Level 2 charger?
About 11.2 hours from empty to full at its 11 kW onboard-charger ceiling (123 kWh battery ÷ 11 kW).
Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a VinFast VF 9 draw on Level 2?
At its full 11 kW rate, the VinFast VF 9 draws about 46A at 240V (kW × 1000 ÷ 240 = amps).
Can a VinFast VF 9 use a 48-amp charger?
Not to any real benefit. The VinFast VF 9's onboard charger tops out at 11 kW (~46A) - a 48A charger doesn't charge it any faster than one already sized to 46A.
How much range does a VinFast VF 9 add per hour on a Level 2 charger?
About 24 miles of range per hour at its 11 kW ceiling (11 kW × 2.15 mi/kWh efficiency).
How much range does an 8-hour overnight charge add to a VinFast VF 9?
Roughly 192 miles from an 8-hour overnight charge (24 mi/hr × 8 hours), or about 240 miles across a 10-hour window.
What's the DC fast charging ceiling for a VinFast VF 9?
Up to 170 kW on a public DC fast charger - well above its 11 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
