EQS SUV 450+
Three-row electric luxury. Here's what its onboard charger actually needs from your home's electrical panel.
Home (Level 2) charging facts
Pulled straight from the EQS SUV 450+'s onboard charger rating - not a generic EV number.

- 9.6 kW
- ~40A at 240V (kW × 1000 ÷ 240)
- Empty-to-full at max Level 2
- 11.3 hrs
- 108.4 kWh battery ÷ 9.6 kW
- Range added per hour
- ~27 mi/hr
- 9.6 kW × 2.8 mi/kWh efficiency
- DC fast charging
- 200 kW max
- Public chargers only - tapers as the battery fills
Typical full-speed install
40A charger on a 50A circuit
Reaches this car's 9.6 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 EQS SUV 450+ specifically, that connector carries up to 9.6 kW at home on Level 2 and up to 200 kW on public DC fast hardware.
Charging speed by circuit size
The Mercedes-Benz EQS SUV's onboard charger can't use more than 9.6 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 | ~16 mi | ~128 mi |
| 32A | 7.7 kW | ~22 mi | ~176 mi |
| 40A | 9.6 kW | ~27 mi | ~216 mi |
| 48A | 9.6 kWcapped by car | ~27 mi | ~216 mi |
Overnight, at full onboard speed
216 mi / 8 hrs
270 mi across a 10-hour window, at 9.6 kW.
Approximate cost to fill from empty
$14.09
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 108.4 kWh - about $0.046/mile.
Mercedes-Benz EQS SUV charging questions
How long does it take to charge a 2022–2026 Mercedes-Benz EQS SUV 450+ on a Level 2 charger?
About 11.3 hours from empty to full at its 9.6 kW onboard-charger ceiling (108.4 kWh battery ÷ 9.6 kW).
Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Mercedes-Benz EQS SUV draw on Level 2?
At its full 9.6 kW rate, the Mercedes-Benz EQS SUV draws about 40A at 240V (kW × 1000 ÷ 240 = amps).
Can a Mercedes-Benz EQS SUV use a 48-amp charger?
Not to any real benefit. The Mercedes-Benz EQS SUV's onboard charger tops out at 9.6 kW (~40A) - a 48A charger doesn't charge it any faster than one already sized to 40A.
How much range does a Mercedes-Benz EQS SUV add per hour on a Level 2 charger?
About 27 miles of range per hour at its 9.6 kW ceiling (9.6 kW × 2.8 mi/kWh efficiency).
How much range does an 8-hour overnight charge add to a Mercedes-Benz EQS SUV?
Roughly 216 miles from an 8-hour overnight charge (27 mi/hr × 8 hours), or about 270 miles across a 10-hour window.
What's the DC fast charging ceiling for a Mercedes-Benz EQS SUV?
Up to 200 kW on a public DC fast charger - well above its 9.6 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
